    This paper reports the study results on manufacturing of low-cost Si substrates by continuous casting method in fiscal 1994. (1) On manufacturing of ingots of 16 piece size, the ingot of nearly 170kg was manufactured by batch process using the Si melt injection unit prepared in last year. (2) On oxygen and carbon contents in wafers, the contents were measured by FT-IR after slicing of the ingot. As a result, the oxygen and carbon contents could be successfully reduced to the targets of 10ppma and 5ppma or less, respectively. (3) The resistivity distribution of the ingot ranged over the target of 1-2ohm-cm. (4) Cells of 100 {times} 100mm{sup 2} wide and 350{mu}m thick were verified by in-house evaluation process. Although lower cell conversion efficiency was found at the center top of the ingot, a vertical efficiency stability was nearly sufficient as a whole. (5) On the crystal growth unit prepared in fiscal 1994, any problems were not found on automatic driving and vibration during moving. 8 figs.

    2004-01-01

    The crystal structure of porcine pancreatic elastase (PPE) complexed with a new benzoxazinone inhibitor, TEI-8362, of human neutrophil elastase (HNE) was determined at 1.8 A resolution. The hydroxyl oxygen of Ser195 opened the benzoxazinone by nucleophilic attack and formed a covalent bond with the carbonyl carbon. Hydrophobic interaction between the terminal benzene of TEI-8362 and the S4 pocket is reinforced by the side chain of Arg217 and has an impact on the ligand binding conformation. Two additional interactions with the oxyanion hole and His57 are introduced to the benzoxazinone structure of TEI-8362. These combinatorial interactions will also exist in HNE and cause high preference of TEI-8362 for HNE.

    Tetralogy of Fallot is a congenital heart disease characterized by underdevelopment of the right ventricular infundibulum. Present study aimed to explore the clinic value of Tei index in assessing right ventricular function of pediatric patients with repaired Tetralogy of Fallot. A total of 45 pediatric patients with repaired Tetralogy of Fallot were recruited and classified into: group A (Tei index 0.7; n=13, aging 4-14 years). The right ventricular Tei index value was related to the clinical characteristics of Tetralogy of Fallot repair patients. Right ventricular Tei index was positively correlated with ventilation time, drainage volumes, and negatively with drug assistance and Intensive Care Unit (ICU) stay, although time for drug assistance and ICU stay were not statically different between group B and group C. There was no significant difference in left ventricular ejection fraction. Tei index is a sensitive indicator of right ventricular dysfunction, and has important clinical value to better our understanding of right ventricular function after tetralogy of Fallot repair.

    This paper reports the study results on the fabrication technology of over-layered TCO on tempered glass in fiscal 1994. (1) On the fabrication technology of heat-resistant over-layered TCO, thermal deformation of TCO substrates was studied by both experiment and numerical computation. The thermal deformation increased with carrier concentration. As the observation result on change in lattice strain of heated TCO films by high-temperature X-ray diffraction, lattice strain was largely affected by thermal expansion. (2) On development of the low-temperature heat treatment method of TCO films, a technological prospect was obtained for fabrication of low-resistance TCO films by heat treatment without strength deterioration of tempered TCO substrates. (3) On development of cost reduction technology, the large-area CVD equipment was devised on the basis of the inline tempering method which tempers substrate glass by air cooling after formation of SnO2 film as fabrication method of tempered TCO. The TCO substrate tempered by air cooling could endure the drop test of 227g and 1.5m. 5 figs., 1 tab.

    Full Text Available Echocardiographic assessment of systolic left ventricular (LV function in patients with severe mitral regurgitation (MR undergoing mitral valve (MV repair can be challenging because the measurement of ejection fraction (EF or fractional area change (FAC in pathological states is of questionable value. The aim of our study was to evaluate the usefulness of the pre-operative Tei Index in predicting left ventricular EF or FAC immediately after MV repair. One hundred and thirty patients undergoing MV repair with sinus rhythm pre- and post-operatively were enrolled in this prospective study. Twenty-six patients were excluded due to absence of sinus rhythm post-operatively. Standard transesophageal examination(IE 33,Philips,Netherlands was performed before and after cardiopulmonary bypass according to the guidelines of the ASE/SCA. FAC was determined in the transgastric midpapillary short-axis view. LV EF was measured in the midesophageal four- and two-chamber view. For calculation of the Tei Index, the deep transgastric and the midesophageal four-chamber view were used. Statistical analysis was performed with SPSS 17.0. values are expressed as mean with standard deviation. LV FAC and EF decreased significantly after MV repair (FAC: 56±12% vs. 50±14%, P<0.001; EF: 58±11 vs. 50±12Έ P<0.001. The Tei Index decreased from 0.66±0.23 before MV repair to 0.41±0.19 afterwards (P<0.001. No relationship between pre-operative Tei Index and post-operative FAC or post-operative EF were found (FAC: r=−0.061, P=0.554; EF: r=−0.29, P=0.771. Conclusion: Pre-operative Tei Index is not a good predictor for post-operative FAC and EF in patients undergoing MV repair.

    The establishment of mature operational procedures and the effort of standardizing and certifying these procedures is a particularly arduous and demanding task which requires strong commitment from management to the existing objectives, administrative stability and continuity, availability of resources, an adequate implementation team with support from all stakeholders and of course great tolerance until tangible results of the investment are shown. Ensuring these conditions, particularly in times of economic crisis, is an extremely difficult task for large organizations such as TEI of Athens where there is heterogeneity in personnel and changes in the administrative hierarchy arise plethora of additional difficulties and require an effective change management. In this work we depict the path of standardization and certification of administrative functions of TEI of Athens, with emphasis on difficulties encountered and how to address them and in particular issues of change management and the culture related to this effort. The requirement for infrastructure needed to be maintained in processes and tools process & strategic management is embodied, in order to evolve mechanisms for continuous improvement processes and storage / recovery of the resulting knowledge. The work concludes with a general design of a road map of internal audit and continuous improvement processes for a large institution of higher education.

    Full Text Available Uma breve análise histórica do conceito geral de alucinação é apresentada e sugere-se que ela surgiu como a generalização injustificada de um modelo perceptual que estava destinado a ser aplicado apenas para a visão e os "sentidos de distância". Neste contexto, considera-se a evolução das alucinações táteis e explora-se sua interação com a teoria psicológica vigente no século XIX. Conclui-se que as alucinações táteis são fenômenos sui generis que não se encaixam no modelo convencional e que a identificação de seu quadro clínico baseia-se, até o momento, em critérios pouco claros. Apresenta-se uma breve revisão da sua taxonomia e utilidade diagnóstica. Algumas implicações mais amplas são delineadas, as quais podem ser relevantes para a concepção geral da alucinação.

    The research and development project is implemented for production of low-cost, large-area modules of CdTe solar cells by the high-quality film-making process and high-function patterning, and the FY 1999 results are reported. The research program for the large-area TCO film-making technologies involves investigations on improvement of SnO{sub 2} film quality by the mist method and continuous film-making, which lead to continuous, stable production of 34 substrates of low resistance of 9.7{omega} on the average. The program for production of the large-area, thin-film CdS/CdTe solar cells involves production of TCO and CdS by the mist method, and patterning of the laminated TCO/CdS film by laser scribing. The CdTe film is formed by the atmospheric pressure CSS method, and treated with CdCl{sub 2} to improve its crystallinity. The CdTe film is patterned by sand blasting, and provided with the carbon and silver electrodes by screen printing, to complete the cell. The process is totally effected at the atmospheric pressure, needing no vacuum device. The CdTe solar cell assembly (130 cells connected in series, opening area: 5,413cm{sup 2}), fabricated on a trial basis, achieves a conversion efficiency of 10%. (NEDO)

    Development will be made on high-performance a-solar cells as part of developing practical application technology for a-solar cells for electric power use. Development will be also made on a low-cost process technology. This paper describes the achievements attained during fiscal 1997. Quality improvement has been realized by using a high RF power hydrogen dilution process on a-Si films for front cells of lamination type cells. Four times faster film forming speed was obtained even by using the VHF plasma CVD process, with film quality equivalent to those made by using the conventional RF process maintained. By optimizing the light enclosing construction, the short circuit current was enhanced by over 20%. Discussions were given on forming homogenous a-Si films by optimizing the conditions for forming films on large-area substrates, which resulted in forming film of 30 cm times 40 cm size with good homogeneity at a film forming speed three times faster than the conventional speed. A surface electrode was formed successfully with good uniformity on a substrate with a size of 60 cm times 90 cm. Productivity greater by over three times the conventional productivity was achieved in patterning of transparent electrodes by using high-output laser. Simultaneous and collective patterning and very small and long size collective patterning were realized in a-Si film selection patterning by using the plasma CVD process. (NEDO)

    The target is a low-cost CdS/CdTe solar cell of a large area (60cm times 90cm), the establishment of mass-production technologies for the cell, and the enhancement of production efficiency. A thin film formation technology of subjecting CdS film organic metal to pyrolysis is established, which reduces photoabsorption loss in the shortwave domain of wavelength of not longer than 500nm, reduces reflection loss in the film, and improves on short-circuit current density. Improvement is also achieved on CdTe film quality and junction quality by use of a proximity sublimation method in a vacuum, when a conversion rate of 16.0% (1cm{sup 2}) is attained which is the highest in the world. Based on the results of the above-said efforts, a 3.3mm-thick glass substrate is employed for CdTe film to develop into a 30cm times 60cm-large size, with the film thereon uniformly thick over a large area thanks to a normal pressure proximity sublimation method. Studies are made toward a process nearer to the ultimate product and, using the patterning technique, a 30cm times 60cm-large CdTe solar cell is tentatively built realizing a conversion rate of 9.8%.

    Full Text Available Abstract: Hyperviscosity syndromes are disorders of infrequent prevalence in which changes of rheological characteristics cause increased resistance to blood flow, endothelial dysfunction, tissue ischemia and bleeding. Signs of hyperviscosity syndrome become clinically overt at the point of 4 centipoise units. We present a case of patient with hyperviscosity syndrome due to Waldenstrom’s macroglobulinemia with negative records on earlier cardiovascular illnesses. Laboratory diagnostic and standard echocardiography did not show any deviation towards increased cardiovascular risk, heart failure or ischemic heart disease. However, unique clinically significant change that could be indirectly related to hyperviscosity syndrome was found with the myocardium performance index (MPI. Tei-index showed median value of 0.75 corresponding to severe grades of myocardial dysfunction earlier described in the literature for other entities. Comprehensive roles of rheological changes in relation to echocardiography, pathophysiology of myocardial performance and cardiovascular continuum might be interesting point for further investigations.

    The Gly-rich loop of cyclin-dependent kinase 2 (CDK2) bound to TEI-I01800 as an MK2 specific inhibitor forms a β-sheet which is a common structure in CDK2–ligand complexes. Here, the reason why TEI-I01800 does not become a strong inhibitor against CDK2 based on the conformation of TEI-I01800 is presented. Mitogen-activated protein kinase-activated protein kinase 2 (MK2 or MAPKAP-K2) is a Ser/Thr kinase from the p38 mitogen-activated protein kinase signalling pathway and plays an important role in inflammatory diseases. The crystal structure of the MK2–TEI-I01800 complex has been reported; its Gly-rich loop was found to form an α-helix, not a β-sheet as has been observed for other Ser/Thr kinases. TEI-I01800 is 177-fold selective against MK2 compared with CDK2; in order to understand the inhibitory mechanism of TEI-I01800, the cyclin-dependent kinase 2 (CDK2) complex structure with TEI-I01800 was determined at 2.0 Å resolution. Interestingly, the Gly-rich loop of CDK2 formed a β-sheet that was different from that of MK2. In MK2, TEI-I01800 changed the secondary structure of the Gly-rich loop from a β-sheet to an α-helix by collision between Leu70 and a p-ethoxyphenyl group at the 7-position and bound to MK2. However, for CDK2, TEI-I01800 bound to CDK2 without this structural change and lost the interaction with the substituent at the 7-position. In summary, the results of this study suggest that the reason for the selectivity of TEI-I01800 is the favourable conformation of TEI-I01800 itself, making it suitable for binding to the α-form MK2.

    2009-09-01

    Full Text Available The Wong Tei Tung archaeological site was discovered in 2003. Two periods have been proposed: an earlier period dating to around 40,000 years bp, and a later period dating to around 7000 years bp, but these dates should be treated cautiously. Initially, reported research found a few traits of the Wong Tei Tung assemblage to be similar to South-east Asia lithics, especially the short axe and Sumatralith cores. It has been reported that the Wong Tei Tung assemblage is a lithic cluster of certain 'techno-complex' implements rather than an archaeological culture; it offers a glimpse of lithic manufacturing in adaptation to its particular coastal environment. The published evidence points to a production of stone tools that considerably exceeded anticipated immediate local need. It is likely, therefore, that products from the site were distributed widely across the Zhujiang Estuary (Pearl River area and beyond (Fig. 1: map. This article presents the results of initial investigations into the geological setting of the site; provides new petrographic descriptions using data obtained from thin sections and geochemical analyses; and makes tentative comparisons with similar archaeological stone tool manufacturing sites in Britain.

    Prognosis of patients with light-chain cardiac amyloidosis (AL-CA) is poor. Speckle tracking imaging (STI) derived longitudinal deformation parameters and Doppler-derived left ventricular (LV) Tei index are valuable predictors of outcome in patients with AL-CA. We estimated the prognostic utility of Tei index and deformation parameters in 58 comprehensively phenotyped patients with AL-CA after a median follow-up of 365 days (quartiles 121, 365 days). The primary end point was all-cause mortality. 19 (33%) patients died during follow-up. Tei index (0.89 ± 0.29 vs. 0.61 ± 0.16, p < 0.001) and E to global early diastolic strain rate ratio (E/GLSR dias ) were higher while global longitudinal systolic strain (GLS sys ) was lower in non-survivors than in survivors (all p < 0.05). Tei index, NYHA functional class, GLS sys and E/GLSR dias were independent predictors of all-cause mortality risk, and Tei index ≥0.9 (HR 7.01, 95% CI 2.43-20.21, p < 0.001) was the best predictor of poor outcome. Combining Tei index and GLS sys yielded the best results on predicting death within 1 year (100% with Tei index ≥0.9 and GLS sys ≤13%) or survival (95% with Tei index ≤0.9 and GLS sys ≥13%). We conclude that 1-year mortality risk in AL-CA patients can be reliably predicted using Tei index or deformation parameters, with combined analysis offering best performance.

    Full Text Available Esta pesquisa investiga a relação entre a utilização de pisos táteis e a conquista de mais liberdade, mais autonomia das pessoas com deficiência visual. Pretende-se compreender se a apropriação desse recurso para o deslocamento “mais livre e mais autônomo” implica o desenvolvimento do senso de pertencimento das pessoas cegas à sociedade, como cidadãos e como sujeitos de direito e de encontros. A pesquisa toma especificamente os modelos de pisos táteis empregados nos calçamentos de duas vias públicas, localizadas no centro da cidade: Rua XV de Novembro e Avenida Marechal Deodoro, sendo a primeira uma via exclusiva para pedestres, no trecho investigado, e a segunda destinada ao tráfego de veículos. Essas vias representam diferentes funções sociais e econômicas na cidade de Curitiba, as quais serão discutidas em relação aos modelos de pisos táteis aí construídos. A rua XV de Novembro representa o espaço do encontro das pessoas, a circulação para fins de lazer, a via de passagem e de ligação entre as Praças Santos Andrade e Osório, o espaço de visualização panorâmica dos principais acontecimentos, a circulação de pessoas de diferentes idades e classes sociais. Já a Avenida Marechal Deodoro é destinada ao trânsito de pessoas com o interesse de aquisição de produtos e serviços. Conceber espaços que contemplem o homem vitruviano consiste no desafio da inclusão urbana. Espaços acessíveis às diferentes formas de manifestação humana constituem um direito inalienável da pessoa para o exercício de sua liberdade fundamental de ir e vir, sua autonomia e sua independência como um sujeito. As entrevistas realizadas com pessoas com deficiência visual revelam a precarização e a insuficiência das estruturas arquitetônicas já conquistadas. Denunciam os limites à plena usabilidade e os obstáculos ao pertencimento à cidade, as barreiras para a subjetivação e apropriação do espaço urbano como

    Objective: To evaluate the clinical value of quantitative tissue velocity imaging (QTVI) and Tei index in detecting left ventricle longitudinal myocardial systolic function in patients with rheumatic mitral stenosis. Methods: 34 patients with rheumatic mitral stenosis (MS) and 36 healthy volunteers were examined by QTVI. The systole peak motion velocity (Vs) of mitral annulus on septum, lateral wall, anterior wall, inferior wall, anterior septum and posterior wall was measured respectively. The interval period of mitral annulus motion was obtained and the Tei index was calculated. Results: The left ventricular ejection fractions (LVEF) was 64.9 ±7.01%, 68.0 ± 6.81% for MS group and the control group. There was no significant difference between the two groups (P>0.05). The systole peak motion velocity (Vs) of mitral annulus on septum, lateral wall, anterior wall, inferior wall, anterior septum and posterior wall was 4.07 ± 1.44 cm/s, 5.33 ±1.72 cm/s, 4.89 ±1.71 cm/s, 4.28 ±1.21 cm/s, 3.94 ± 1.46 cm/s, 5.19 ±1.81 cm/s respectively and average velocity (AV) of mitral valve annulus was 4.61 ± 1.62 cm/s in MS group. The systole peak motion velocity (Vs) of mitral annulus on septum, lateral wall, anterior wall, inferior wall, anterior septum and posterior wall was 6.11 ± 0.96 cm/s, 8.74 ±1.40 cm/s, 8.45 ±1.33 cm/s, 6.59 ± 0.94 cm/s, 6.01 ± 1.25 cm/s, 7.70 ±1.46 cm/s respectively and average velocity (AV) of mitral valve annulus was 7.27 ±1.63 cm/s in the control group. Compared with the control group, Vs and AV of mitral valve annulus is MS group decreased dramatically and had significant difference (P<0.01). Moreover, compared with Tei index of the control group (0.21 ±3.47), Tei index of the MS group (0.50 ±0.12) had greatly increased and had significant difference (P<0.01). Conclusion: Sub-clinical damage of systolic function of the left ventricle in patients with rheumatic mitral stenosis could not be detected by LVEF. Combined use QTVI and Tei

    Gail Falkingham

    2005-04-01

    Full Text Available This article has arisen through the author's interest in two contemporary issues within archaeology: the production and dissemination of grey literature and the potential of XML. Grey literature is examined, with specific reference to unpublished reports literature produced in the present climate of developer-funded archaeology in England. There are concerns about the accessibility of this literature, both from within and beyond the archaeological profession. The vast majority of reports are word-processed and then printed in hard-copy format for limited distribution. The original, digital document however, has largely been seen as a by-product. Awareness of the importance of these digital reports, and their preservation must be raised. Electronic means of delivery and dissemination via the World Wide Web offer huge potential and present opportunities for new ways of working. Archaeology is not alone in seeking to promote the accessibility of grey literature; indeed there are many disciplines that have created online initiatives aiming to do just this, utilising a variety of means and a range of electronic file formats. The use of XML technology appears to offer many advantages over traditional formats, such as word-processed, PDF and even (XHTML files, particularly with regard to the manipulation and presentation of encoded electronic text. Increasingly, XML technology is being used for electronic delivery and dissemination and the pros and cons of so doing are discussed in this article. This theme has been developed by the author through a 'proof of concept' practical case study of three unpublished grey literature archaeology reports from the North Yorkshire Historic Environment Record. XML documents have been created from the original word-processed electronic reports by the manual application of XML markup, the methodology for which was devised following the XML version of the Text Encoding Initiative's TEI P4 Guidelines.

    2010-03-01

    Full Text Available In this new millennium the relatively young field of ecocriticism has had to face important transdisciplinary, transnational, and transnatural challenges. This article attempts to demonstrate how two of the major changes that environmental criticism is currently undergoing, the transnational turn and the transnatural challenge, have both been encoded in Through the Arc of the Rain Forest (1990, the first novel published by Karen Tei Yamashita. I particularly focus on a significant episode in Through the Arc of the Rain Forest, when a peculiar anthropogenic ecosystem is discovered, and interpret it according to Leo Marx’s classic paradigm of “the machine in the garden.” I intend to prove that Yamashita’s novel not only revisits the old master theory but also revamps it by destabilizing the classic human-nature divide inherent in first-wave ecocriticism and by adding the transnational ingredient. Thus, the machine-in-the-garden paradigm is updated in order to incorporate the broadening of current environmental criticism, both literally (globalization and conceptually (transnatural nature. While at times Marx’s paradigm may metamorphose in intriguing ways, the old trope also corroborates its continuing validity. Though filtered by the sieve of globalization and shaken by the emergence of cyborg ecosystems, “the machine in the garden” has survived as a compelling ecocritical framework, even if it occasionally mutates into a junkyard in the jungle.

    Vacancy-ordered double perovskites of the general formula, A2BX6, are a family of perovskite derivatives composed of a face-centered lattice of nearly isolated [BX6] units with A-site cations occupying the cuboctahedral voids. Despite the presence of isolated octahedral units, the close-packed iodide lattice provides significant electronic dispersion, such that Cs2SnI6 has recently been explored for applications in photovoltaic devices. To elucidate the structure-property relationships of these materials, we have synthesized the solid solution Cs2Sn1-xTexI6. However, even though tellurium substitution increases electronic dispersion via closer I-I contact distances, the substitution experimentally yields insulating behavior from a significant decrease in carrier concentration and mobility. Density functional calculations of native defects in Cs2SnI6 reveal that iodine vacancies exhibit a low enthalpy of formation and the defect energy level is a shallow donor to the conduction band, rendering the material tolerant to these defect states. The increased covalency of Te-I bonding renders the formation of iodine vacancy states unfavorable, and is responsible for the reduction in conductivity upon Te substitution. Additionally, Cs2TeI6 is intolerant to the formation of these defects, as the defect level occurs deep within the band gap and thus localizes potential mobile charge carriers. In these vacancy-ordered double perovskites, the close-packed lattice of iodine provides significant electronic dispersion, while the interaction of the B- and X-site ions dictates the properties as they pertain to electronic structure and defect tolerance. This simplified perspective -- based on extensive experimental and theoretical analysis -- provides a platform from which to understand structure-property relationships in functional perovskite halides.

    The objective of this dissertation is to investigate determinants and consequences of asymmetric cost behavior. Asymmetric cost behavior arises if the change in costs is different for increases in activity compared to equivalent decreases in activity. In this case, costs are termed “sticky......” if the change is less when activity falls than when activity rises, whereas costs are termed “anti-sticky” if the change is more when activity falls than when activity rises. Understanding such cost behavior is especially relevant for decision-makers and financial analysts that rely on accurate cost information...

Com base nestas características, este trabalho objetivou avaliar a atratividade aos adultos do predador Chrysoperla externa. Foram utilizados folhas e caules de coentro, endro e erva-doce, coletados aos 30 e 60 dias após a semeadura. As plantas foram dispostas em olfatômetro de quatro vias (formato de "X" disponibilizando-se os odores para machos e fêmeas, virgens e acasalados, em testes de livre escolha. Ao serem liberados individualmente no interior do olfatômetro, foram cronometrados cinco minutos e contabilizado o tempo total de permanência do inseto em cada braço do aparelho. Os dados foram analisados pelo teste c², com frequência esperada de 25%. Estudou-se o rendimento de óleo essencial das três espécies de plantas, 30 e 60 dias após a semeadura, utilizando-se do método de hidrodestilação. A composição química dos óleos foi determinada por cromatografia gasosa acoplada a espectrômetro de massas. Verificou-se que adultos virgens têm preferência por plantas de coentro, enquanto os acasalados preferem plantas de erva-doce, ambas coletadas aos 30 dias. Plantas com 60 dias não proporcionaram resposta atrativa aos adultos de C. externa. O rendimento de óleo tendeu a aumentar com o desenvolvimento fenológico da planta. A composição química do óleo de coentro revelou, como componentes majoritários, o (2E-decenal e decanal e, para erva-doce, a maior concentração foi de (E-anetol.

    Full Text Available O manejo de resíduos orgânicos sob condições anaeróbias pode, durante a fase inicial do processo metabólico, levar à formação de ácidos orgânicos voláteis (C1-C4, cuja atividade fitotóxica determina perdas substanciais à produção vegetal. A caracterização da fitoxidez desses ácidos foi o objetivo da presente revisão. O tipo e quantidade dos ácidos produzidos durante o processo dependem, basicamente, da quantidade e qualidade do resíduo adicionado, sendo a fitotoxidez diretamente relacionada ao comprimento da cadeia de carbonos e concentração dos ácidos e ao pH do meio em que se encontram. Os principais efeitos estão associados à inibição da germinação e da expansão radicular, como resultado de lesões causadas ao tecido meristemático da radícula ou de limitações à respiração, conduzindo à inibição da divisão celular.Volatile organic acids (C1-C4 can be build up during the first stages of metabolic process under anaerobic conditions of organic residues management. The phytotoxicity can leads to significant losses of crop production. The phytotoxicity of this acids was the aim of this revision. The type and amount of acids produced during the process are basically dependent on the amount and quality of the residue and the phytoxicity is directly related to the length of C compounds, to the acid concentration, and to the soil solution pH. The main effects, as germination inhibition and root expansion, are related to damaged root meristematic tissue or respiration inhibition and consequently leading to inhibition of cell division.

Foram utilizadas 4 vacas holandesas providas de cânula ruminal, 5 períodos e 5 dietas experimentais em um delineamento estatístico em Quadrado Latino Incompleto. Amostras de fluido ruminal foram coletadas 0, 2, 4, 6, 8 e 24 horas após a alimentação para determinação de ácidos graxos voláteis. A produção de ácido acético foi maior (p0,05. Nestas condições experimentais os resultados sugerem que a polpa de citros pode ser utilizada em substituição ao volumoso causando alterações desejáveis nas condições ruminais. Os efeitos do milho sobre o padrão de fermentação ruminal são característicos de um alimento concentrado. A associação do milho com a polpa de citros é uma alternativa para minimizar estes efeitos.The present work was conducted to evaluate the effects of citrus pulp and corn in when partially replacing corn silage in lactating dairy cattle rations. Four Holstein volatile fatty acids production, cows with ruminal cannula were used for five periods and five experimental rations in an Incomplete Latin Square experimental design. Ruminal fluid samples were collected at 0, 2, 4, 6, 8 and 24 hours after feeding, to determine volatile fatty acids. The production of acetic acid was higher (p0,05. Under these experimental conditions, the results suggested that citrus pulp could replace the roughage resulting in desirable changes in the ruminal conditions. The effects of corn in ruminal fermentation pattern were typical of a concentrated feed. The association of corn with citrus pulp is an alternative option to minimize effects.

  6. Troubleshooting Costs

    Science.gov (United States)

    Kornacki, Jeffrey L.

    Seventy-six million cases of foodborne disease occur each year in the United States alone. Medical and lost productivity costs of the most common pathogens are estimated to be 5.6-9.4 billion. Product recalls, whether from foodborne illness or spoilage, result in added costs to manufacturers in a variety of ways. These may include expenses associated with lawsuits from real or allegedly stricken individuals and lawsuits from shorted customers. Other costs include those associated with efforts involved in finding the source of the contamination and eliminating it and include time when lines are shut down and therefore non-productive, additional non-routine testing, consultant fees, time and personnel required to overhaul the entire food safety system, lost market share to competitors, and the cost associated with redesign of the factory and redesign or acquisition of more hygienic equipment. The cost associated with an effective quality assurance plan is well worth the effort to prevent the situations described.

  8. Minimizing Costs Can Be Costly

    Rasmus Rasmussen

    2010-01-01

    Full Text Available A quite common practice, even in academic literature, is to simplify a decision problem and model it as a cost-minimizing problem. In fact, some type of models has been standardized to minimization problems, like Quadratic Assignment Problems (QAPs, where a maximization formulation would be treated as a “generalized” QAP and not solvable by many of the specially designed softwares for QAP. Ignoring revenues when modeling a decision problem works only if costs can be separated from the decisions influencing revenues. More often than we think this is not the case, and minimizing costs will not lead to maximized profit. This will be demonstrated using spreadsheets to solve a small example. The example is also used to demonstrate other pitfalls in network models: the inability to generally balance the problem or allocate costs in advance, and the tendency to anticipate a specific type of solution and thereby make constraints too limiting when formulating the problem.

    phage types, predominantly only penicillin resistant. We investigated whether isolates of this epidemic were associated with a fitness cost, and we employed a mathematical model to ask whether these fitness costs could have led to the observed reduction in frequency. Bacteraemia isolates of S. aureus...... from Denmark have been stored since 1957. We chose 40 S. aureus isolates belonging to phage complex 83A, clonal complex 8 based on spa type, ranging in time of isolation from 1957 to 1980 and with varyous antibiograms, including both methicillin-resistant and -susceptible isolates. The relative fitness...... of each isolate was determined in a growth competition assay with a reference isolate. Significant fitness costs of 215 were determined for the MRSA isolates studied. There was a significant negative correlation between number of antibiotic resistances and relative fitness. Multiple regression analysis...

    2015-04-01

    There is increasing demand on cost effective Structural Health Monitoring systems for buildings as well as important and/or critical constructions. The front end for all these systems is the accelerometer. We present a comparative study of two low cost MEMS accelaration sensors against a very sensitive, high dynamic range strong motion accelerometer of force balance type but much more expensive. A real experiment was realized by deploying the three sesnors in a reinforced concrete building of the premises of TEI of Crete at Chania Crete, an earthquake prone region. The analysis of the collected accelararion data from many seismic events indicates that all sensors are able to efficiently reveal the seismic response of the construction in terms of PSD. Furthermore, it is shown that coherence diagrams between excitation and response of the building under study, depict structural characteristics but also the seismic energy distribution. This work is supported by the Archimedes III Program of the Ministry of Education of Greece, through the Operational Program "Educational and Lifelong Learning", in the framework of the project entitled "Interdisciplinary Multi-Scale Research of Earthquake Physics and Seismotectonics at the front of the Hellenic Arc (IMPACT-ARC)" and is co-financed by the European Union (European Social Fund) and Greek national funds.

  17. Cost restructuring

    Schmidt, J.A.

    1991-01-01

    This paper reports on the cost restructuring of the petroleum industry. This current decade is likely to be one of the most challenging for the petroleum industry. Though petroleum remains among the world's biggest businesses, news of consolidations, restructuring, and layoffs permeates the oil patch from the Gulf of Mexico to the Arctic Isles. The recessionary economy has accelerated these changes, particularly in the upstream sector. Today, even the best-managed companies are transforming their cost structures, and companies that fail to do likewise probably won't survive as independent companies. Indeed, significant consolidation took place during the 1980s. More consolidations can be expected in this decade for companies that do not adapt to the economic realities of the mature business

    Full Text Available Volatile fatty acids (VFA absorption and metabolic capacity of rumen and omasum were compared, in vitro. Fragments of rumen wall and omasum laminae were taken from eight adult crossbred bovines. An isolated fragment of the mucosa was fitted in a tissue diffusion chamber. Valeric acid and CrEDTA were added to ruminal fluid and placed on the mucosal side and buffer solution was placed on the serosal side. Fractional absorption rates were measured by exponential VFA:Cr ratio decay over time. Metabolism rate was determined as the difference between VFA absorbed and VFA which appeared on the serosal side over time. Mitotic index was higher in omasum (0.52% than in rumen epithelium (0.28%. VFA fractional absorption rate was higher in omasum (4.6%/h.cm² than in rumen (0.4%/h.cm². Acetate, propionate, butyrate, and valerate showed similar fractional absorption rates in both fragments. Percentage of metabolized acetate and propionate was lower than butyrate and valerate in both stomach compartments. In the rumen, individual VFA metabolism rates were similar (mean of 7.7 , but in the omasum, valerate (90.0 was more metabolized than butyrate (59.6 propionate (69.8 and acetate (51.7 . Correlation between VFA metabolism and mitotic index was positive in the rumen and in the omasum. In conclusion, VFA metabolism and absorption potential per surface of the omasum is higher than that of the rumen. Variations on rumen and omasum absorption capacities occur in the same way, and there are indications that factors capable of stimulating rumen wall proliferation are similarly capable of stimulating omasum walls.A capacidade de absorção e metabolismo de ácidos graxos voláteis (AGV pelo rúmen e omaso foi comparada, in vitro.

    Full Text Available The conversion of p-coumaric acid, ferulic acid, and caffeic acid into 4-ethylphenol, 4-ethylguaiacol and 4-ethylcatechol was studied in Dekkera bruxellensis ISA 1791 under defined conditions in a synthetic medium and in a red wine. Liquid chromatography (HPLC-DAD was used to quantify the phenolic acids, and gas chromatography (GC coupled to a FID detector was used to quantify volatile phenols using a novel analytical methodology that does not require sample derivatization. Identification was achieved by gas chromatography-mass detection (GC-MS. The results show that phenolic acids concentration decreases while volatile phenols concentration increases. The proportion of caffeic acid taken up by Dekkera bruxellensis is lower than that for p-coumaric or ferulic acid; therefore less 4-ethylcatechol is formed. More important, 4-ethylcathecol synthesis by Dekkera bruxellensis in wine has never been demonstrated so far. These results contribute decisively to a better understanding of the origin of the volatile phenols in wines. The accumulation of these compounds in wine is nowadays regarded as one of the key factors of quality control.A transformação do ácido p-cumárico, ácido ferúlico e ácido cafeico em 4-etilfenol, 4-etilguaiacol e 4-etilcatecol foi estudada na presença de Dekkera bruxelensis ISA 1791, sob condições controladas, em meio sintético e em vinho tinto.

Os VOC foram coletados por meio de um condensador de gases, conectado na zona de desgaseificação da extrusora, e analisados por espectrometria no infravermelho (FTIR-ATR. A degradação do polímero foi acompanhada através da cromatografia de exclusão por tamanho e FTIR. À temperatura de 180 °C a degradação do polipropileno não gerou quantidades coletáveis de compostos orgânicos voláteis. Por outro lado, a partir de 200 °C houve geração de compostos olefínicos, não voláteis à temperatura ambiente, que aumentaram em quantidade com o aumento da temperatura de extrusão. A Função de Distribuição de Cisão de Cadeia (CSDF mostrou que a baixas temperaturas, 180 e 200 °C, o mecanismo de degradação do polipropileno é preferencialmente por cisão de cadeia com alguma ramificação e/ou reticulação. Entretanto, nas temperaturas de extrusão mais altas, 220 e 240 °C, o mecanismo de degradação envolve exclusivamente cisão de cadeia e do tipo preferencial, ou seja, o número de cisões aumenta com o aumento da massa molar inicial da cadeia polimérica original.The thermo-mechanical degradation of an unstabilized polypropylene copolymer during extrusion at different temperatures (from 180 to 240 °C and the production of volatile organic compounds (VOC were studied.

The polymer degradation was followed via size exclusion chromatography and FTIR. At low extrusion temperatures (180 °C the PP degradation produces undetectable quantities of VOC's. On the other hand, starting from 200 °C, there is the formation of olefinic compounds of molecular weight not volatile at room temperature

    Full Text Available Firms are coping with a competitive scenario characterized by quick changes produced by internationalization, concentration, restructuring, technological innovation processes and financial market crisis. On the one hand market enlargement have increased the number and the segmentation of customers and have raised the number of competitors, on the other hand technological innovation has reduced product life cycle. So firms have to adjust their management models to this scenario, pursuing customer satisfaction and respecting cost constraints. In a context where price is a variable fixed by the market, firms have to switch from the cost measurement logic to the cost management one, adopting target costing methodology. The target costing process is a price driven, customer oriented profit planning and cost management system. It works, in a cross functional way, from the design stage throughout all the product life cycle and it involves the entire value chain. The process implementation needs a costing methodology consistent with the cost management logic. The aim of the paper is to focus on Activity Based Costing (ABC application to target costing process. So: -it analyzes target costing logic and phases, basing on a literary review, in order to highlight the costing needs related to this process; -it shows, through a numerical example, how to structure a flexible ABC model – characterized by the separation between variable, fixed in the short and fixed costs - that effectively supports target costing process in the cost measurement phase (drifting cost determination and in the target cost alignment; -it points out the effectiveness of the Activity Based Costing as a model of cost measurement applicable to the supplier choice and as a support for supply cost management which have an important role in target costing process. The activity based information allows a firm to optimize the supplier choice by following the method of minimizing the

    Full Text Available Quality has a cost and this fact cannot be denied. In the same time, it is true that non-quality is more expensive. Quality is considered asbeing expensive because no one tries to calculate non-quality costs. Out of the final cost of a product, non-quality stands for 20% up to 35%.According to this idea all the economic sectors contain error costs caused by the mistakes made during the production process. To have a realconsummation situation, it is necessary to know the cost quantum. The final quality cost is the result of the following costs: prevention costs,necessary to preclude errors; evaluation costs, as results of a final product evaluation, and failure costs, generated by the non – attainment ofproduct’s purpose. The gross of these costs stand for the total quality costs. Nowadays, the problem inheres in how much this quality cost representsout of the final cost.

    Full Text Available Cost information system plays an important role in every organization in the decision making process. An important task of management is ensuring control of the operations, processes, sectors, and not ultimately on costs. Although in achieving the objectives of an organization compete more control systems (production control, quality control, etc., the cost information system is important because monitors results of the other. Detailed analysis of costs, production cost calculation, quantification of losses, estimate the work efficiency provides a solid basis for financial control. Knowledge of the costs is a decisive factor in taking decisions and planning future activities. Managers are concerned about the costs that will appear in the future, their level underpinning the supply and production decisions as well as price policy. An important factor is the efficiency of cost information system in such a way that the information provided by it may be useful for decisions and planning of the work.

    Full Text Available Usando um amostrador automático, os "headspaces" de três marcas comerciais de café torrado e moído foram analisados qualitativa e quantitativamente quanto a composição dos voláteis responsáveis pelo aroma através da técnica de cromatografia gasosa/espectrometria de massas. Uma vez que a metodologia não envolveu isolamento ou concentração dos aromas, suas proporções naturais foram mantidas, além de simplificar o preparo das amostras. O emprego do amostrador automático permitiu também boa resolução dos picos cromatográficos sem o emprego de criogenia, contribuindo para redução no tempo de análise. Noventa e um componentes puderam ser identificados, sendo que alguns compostos conhecidos como presentes em café como o dimetilsulfeto, metional e furfuril mercaptana não foram detectados. Os voláteis presentes em maior concentração puderam ser quantificados com o auxílio de dois padrões internos. A técnica se provou viável, tanto para caracterização como para quantificação de voláteis de café.Employing an automatic headspace sampler, the headspaces of three commercial brands of ground roasted coffee were qualitatively and quantitatively analyzed by gas chromatography / mass spectrometry. Since the methodology did not involve aroma isolation or concentration, their natural proportions were maintained, providing a more accurate composition of the flavors, and simplifying sample preparation. The automatic sampler allowed good resolution of the chromatographic peaks without cryofocusing the samples at the head of the column during injection, reducing analysis time. Ninety one compounds were identified and some known coffee volatiles, such as dimethyl sulphide, methional and furfuryl mercaptan were not detected. The more concentrated volatiles could be identified using two internal standards. The technique proved viable, for both characterization and for quantification of coffee volatiles.

    This paper resolves several controversies in CEA. Generalizing [Garber, A.M., Phelps, C.E., 1997. Economic foundations of cost-effectiveness analysis. Journal of Health Economics 16 (1), 1-31], the paper shows accounting for unrelated future costs distorts decision making. After replicating [Meltzer, D., 1997. Accounting for future costs in medical cost-effectiveness analysis. Journal of Health Economics 16 (1), 33-64] quite different conclusion that unrelated future costs should be included in CEA, the paper shows that Meltzer's findings result from modeling the budget constraint as an annuity, which is problematic. The paper also shows that related costs should be included in CEA. This holds for a variety of models, including a health maximization model. CEA should treat costs in the manner recommended by Garber and Phelps.

    Full Text Available The adulteration of the product Ilex paraguariensis with other Ilex species is a mAjor problem for maté tea producers. In this work, three species of Ilex were evaluated for their volatile composition by headspace solid phase microextraction coupled to gas chromatography and mass spectrum detector (HS-SPME/GC-MS. The adulterating species I. dumnosa and I. theizans Mart. ex Reissek presented a different profile of volatile organic compounds when compared to I. paraguariensis. Aldehydes methyl-butanal, pentanal, hexanal, heptanal and nonanal were detected only in the adulterating species. This result suggests that such compounds are potential chemical markers for identification of adulteration and quality analysis of products based on Ilex paraguariensis.A adulteração do produto Ilex paraguariensis com outras espécies de Ilex é um dos principais problemas dos produtores de erva-mate.

    The GKSS has a cost accounting system comprising cost type, cost centre and cost unit accounting which permits of a comprehensive and detailed supervision of the accural of costs and use of funds, makes price setting for outside orders possible and provides the necessary data for decision-making and planning. It fulfills the requirement for an ordered accounting system; it is therefore guaranteed that there exists between financial accounts department and cost accounting a proper demarcation and transition, that costs are accounted fully only on the basis of vouchers and only once, evaluation and distribution are unified and the principle of causation is observed. Two employees are engaged in costs and services accounting. Although we strive to effect adaptations as swiftly as possible, and constantly to adapt refinements and supplementary processes for the improvement of the system, this can only occur within the scope of, and with the exactitude necessary for the required information.

    A five year planning is made in which the available money is distributed to the expected programmes. This five year plan is used as basis for working plan and budget for the next year. In the working plan all financial means are divided into kinds of costs, cost centres and cost units. Based on this working plan and the relevant budgets the tariffs are calculated per working centre (cost centre). The tariffs are fixed for a whole year. Up till now these tariffs are also basis for the cost unit accounting at the end of the year together with the results of the time registration. The estimated work shop services for the working centres are included in the tariffs. For the allocation of overhead costs ECN uses dynamic keys. Depreciation costs with respect to instruments, investments etc. are determined per working centre according to a computer programme. The cost unit related costs are charged directly to cost unit. This implies that project related in instruments are looked upon as running costs. In the future we will try to refine the present cost accounting system still further in this way that we will look upon a cost centre as a profit centre. Furthermore we will try to analyse the tariff and calculation deviations and under/over occupation deviations afterwards (post calculation). The information provided to the management knows a hierachic construction: project information to projectleader, programme (compound projects) information to programme coordinator, cost centre summary to department heads, attention area (compound programme) information to programme coordinator and managing director, ECN research (compound attention areas) information to general management, information re kind of costs to relevant persons, f.e. surveys of expenditure for part time personnel to personnel bureau.

    Most of the power transmission system in the province of Ontario is owned and operated as a regulated monopoly by Ontario Hydro Services Company (OHSC). Local distribution systems deliver to end-users from bulk supply points within a service territory. OHSC distributes to approximately one million, mostly rural customers, while the approximately 250 municipal utilities together serve about two million, mostly urban customers. Under the Energy Competition Act of 1998 local distribution companies will face some new challenges, including unbundled billing systems, a broader range of distribution costs, increased costs, made up of corporate taxes or payments in lieu of taxes and added costs for regulatory affairs. The consultants provide a detailed discussion of the components of distribution costs, the three components of the typical budget process (capital expenditures, (CAPEX), operating and maintenance (O and M) and administration and corporate (GA and C), a summary of some typical distribution costs in Ontario, and the estimated impacts of the Energy Competition Act (ECA) compliance on charges and rates. Various mitigation strategies are also reviewed. Among these are joint ventures by local distribution companies to reduce ECA compliance costs, re-examination of controllable costs, temporary reduction of the allowable return on equity (ROE) by 50 per cent, and/or reducing the competitive transition charge (CTC). It is estimated that either one of these two reductions could eliminate the full amount of the five to seven per cent uplift in delivered energy service costs. The conclusion of the consultants is that local distribution delivery charges will make up a greater proportion of end-user cost in the future than it has in the past. An increase to customers of about five per cent is expected when the competitive electricity market opens and unbundled billing begins. The cost increase could be mitigated by a combination of actions that would be needed for about

    If doctors take the costs of treatment into account when prescribing medication, their objectives differ from their patients' objectives because the patients are insured. This misalignment of interests hampers communication between patient and doctor. Giving cost incentives to doctors increases...... welfare if (i) the doctor's examination technology is sufficiently good or (ii) (marginal) costs of treatment are high enough.

    War is costly. But peace cost is even higher. The destruction of weapons (mines, nuclear weapons, chemical weapons) is much more expensive than their manufacturing. The soldiers demobilization cost is enormous, for instance in Angola, Mozambique, Nicaragua, Zimbabwe the demobilization of 270000 soldiers cost 2.5 10 9 francs. The measures intended to reduce the war risk are also expensive. That is why the arsenal of ex USSR is still intact. Today no international agency is entirely dedicated to peace building. The question is how would cost such an agency? (O.L.). 5 refs., 2 figs

    Full Text Available Este artigo apresenta uma visão integrada das principais causas de acúmulo de ácidos graxos voláteis (AGVs em reatores anaeróbios. O acúmulo de acetato observado durante as condições de choque de carga e/ou estresse ocorre provavelmente devido às limitações cinéticas dos microrganismos metanogênicos, que é acentuada com a redução do pH. O acúmulo de acetato e hidrogênio na fase líquida pode, por sua vez, desencadear limitações termodinâmicas e conseqüente acúmulo de propionato e butirato. A manutenção de condições ideais de crescimento dos microrganismos metanogênicos é uma estratégia de controle para reduzir o acúmulo de acetato, embora não seja efetiva em reduzir a concentração de hidrogênio dissolvida ao ponto em que não haja limitação sintrófica. As estratégias para mitigação das limitações termodinâmicas poderiam envolver a regulação da concentração de acetato através do uso de resinas ou membranas, e a separação espacial de microrganismos através da granulação ou tratamento em duas fases.This paper presents an integrated approach of the main reasons for the accumulation of volatile fatty acids (VFAs in anaerobic reactors. The build up of acetate during shock loads and/or stress conditions is likely to occur due to kinetic limitations of methanogenic microrganisms, which is enhanced by pH reduction. Acumulation of acetate and hydrogen in the liquid phase will set the stage for the accumulation of other VFAs, such as propionate and butyrate, due to thermodynamic inhibition. By mantaining the ideal growth conditions for the methanogens it may be possible to reduce the acetate build up, although it may not be effective in reducing the concentration of dissolved hydrogen so that thermodynamic inhibition is avoided. The strategies to mitigate themodynamic inhibition could involve regulation of acetate by means of membrane or resins, and spacial separation of microrganisms by granulation or

    The first phase of the Depleted Uranium Hexafluoride Management Program (Program)--management strategy selection--consists of several program elements: Technology Assessment, Engineering Analysis, Cost Analysis, and preparation of an Environmental Impact Statement (EIS). Cost Analysis will estimate the life-cycle costs associated with each of the long-term management strategy alternatives for depleted uranium hexafluoride (UF6). The scope of Cost Analysis will include all major expenditures, from the planning and design stages through decontamination and decommissioning. The costs will be estimated at a scoping or preconceptual design level and are intended to assist decision makers in comparing alternatives for further consideration. They will not be absolute costs or bid-document costs. The purpose of the Cost Analysis Guidelines is to establish a consistent approach to analyzing of cost alternatives for managing Department of Energy's (DOE's) stocks of depleted uranium hexafluoride (DUF6). The component modules that make up the DUF6 management program differ substantially in operational maintenance, process-options, requirements for R and D, equipment, facilities, regulatory compliance, (O and M), and operations risk. To facilitate a consistent and equitable comparison of costs, the guidelines offer common definitions, assumptions or basis, and limitations integrated with a standard approach to the analysis. Further, the goal is to evaluate total net life-cycle costs and display them in a way that gives DOE the capability to evaluate a variety of overall DUF6 management strategies, including commercial potential. The cost estimates reflect the preconceptual level of the designs. They will be appropriate for distinguishing among management strategies

    As typically practiced in the petroleum/ natural gas industry, most economic calculations leave out sunk costs. Integrated businesses can be hurt by the omission of sunk costs because profits and costs are not allocated properly among the various business segments. Not only can the traditional sunk-cost practice lead to predictably bad decisions, but a company that operates under such a policy will have no idea how to allocate resources among its operating components; almost none of its calculated returns will be correct. This paper reports that the solution is to include asset value as part of the investment in the calculation

    This report describes the activity based costing method used to acquire variable (volume dependent or avoidable) waste management cost data for routine operations at Department of Energy (DOE) facilities. Waste volumes from environmental restoration, facility stabilization activities, and legacy waste were specifically excluded from this effort. A core team consisting of Idaho National Engineering Laboratory, Los Alamos National Laboratory, Rocky Flats Environmental Technology Site, and Oak Ridge Reservation developed and piloted the methodology, which can be used to determine avoidable waste management costs. The method developed to gather information was based on activity based costing, which is a common industrial engineering technique. Sites submitted separate flow diagrams that showed the progression of work from activity to activity for each waste type or treatability group. Each activity on a flow diagram was described in a narrative, which detailed the scope of the activity. Labor and material costs based on a unit quantity of waste being processed were then summed to generate a total cost for that flow diagram. Cross-complex values were calculated by determining a weighted average for each waste type or treatability group based on the volume generated. This study will provide DOE and contractors with a better understanding of waste management processes and their associated costs. Other potential benefits include providing cost data for sites to perform consistent cost/benefit analysis of waste minimization and pollution prevention (WMIN/PP) options identified during pollution prevention opportunity assessments and providing a means for prioritizing and allocating limited resources for WMIN/PP.

    Gonzalez-Sanchez, M Beatriz; Lopez-Valeiras, Ernesto; Morente, Manuel M; Fernández Lago, Orlando

    2013-10-01

    Current economic conditions and budget constraints in publicly funded biomedical research have brought about a renewed interest in analyzing the cost and economic viability of research infrastructures. However, there are no proposals for specific cost accounting models for these types of organizations in the international scientific literature. The aim of this paper is to present the basis of a cost analysis model useful for any biobank regardless of the human biological samples that it stores for biomedical research. The development of a unique cost model for biobanks can be a complicated task due to the diversity of the biological samples they store. Different types of samples (DNA, tumor tissues, blood, serum, etc.) require different production processes. Nonetheless, the common basic steps of the production process can be identified. Thus, the costs incurred in each step can be analyzed in detail to provide cost information. Six stages and four cost objects were obtained by taking the production processes of biobanks belonging to the Spanish National Biobank Network as a starting point. Templates and examples are provided to help managers to identify and classify the costs involved in their own biobanks to implement the model. The application of this methodology will provide accurate information on cost objects, along with useful information to give an economic value to the stored samples, to analyze the efficiency of the production process and to evaluate the viability of some sample collections.

  15. External costs of electricity

    Rabl, A.; Spadaro, J.V.

    2005-01-01

    This article presents a synthesis of the ExternE project (External costs of Energy) of the European community about the external costs of power generation. Pollution impacts are calculated using an 'impact pathways' analysis, i.e. an analysis of the emission - dispersion - dose-response function - cost evaluation chain. Results are presented for different fuel cycles (with several technological variants) with their confidence intervals. The environmental impact costs are particularly high for coal: for instance, in France, for coal-fired power plants it is of the same order as the electricity retail price. For natural gas, this cost is about a third of the one for coal. On the contrary, the environmental impact costs for nuclear and renewable energies are low, typically of few per cent of the electricity price. The main part of these costs corresponds to the sanitary impacts, in particular the untimely mortality. In order to avoid any controversy about the cost evaluation of mortality, the reduction of the expectation of life due to the different fuel cycles is also indicated and the risks linked with nuclear energy are presented using several comparisons.

  8. [The cost of sepsis].

    Moerer, O; Burchardi, H

    2006-06-01

    In recent years great efforts in clinical sepsis research have led to a better understanding of the underlying pathophysiology and new therapeutic approaches including drugs and supportive care. Despite this success, severe sepsis remains a serious health care problem. Each year approximately 75,000 patients in Germany and approximately 750,000 patients in the USA suffer from severe sepsis. The length of stay and the cost of laborious therapies lead to high intensive care unit (ICU) costs. Sepsis causes a significant national socioeconomic burden if indirect costs due to productivity loss are included and in Germany severe sepsis has been estimated to generate costs between 3.6 and 7.7 billion Euro annually. Thus, this complex and life-threatening disease has been identified as a high cost driver not only for the ICU, but also from the perspectives of hospitals and society. To improve the outcome of severe sepsis, innovative drugs and treatment strategies are urgently needed. Some drugs and strategies already offer promising results and will probably play a major role in the future. Even though their cost-effectiveness is likely, intensive care medicine has to carry a substantial economic burden. This article summarizes studies focusing on the evaluation of direct or indirect costs of sepsis and the cost-effectiveness of new therapies.

    The calculation of electric power production reference costs is used in France, even in the present case of over-capacity, for comparing the relative interest of the various means of power generation (nuclear plants, coal plants, hydroelectricity, gas combined cycles, etc.) and as an aid for future investment decisions. Reference costs show a sharp decrease between 1993 and 1997 due to advancements in nuclear plant operating ability and fossil fuel price decrease. Actuarial rates, plant service life, fuel costs and exchange rates are important parameters. The various costs from the research stage to the waste processing stages are discussed and the reference costs of the various power generation systems are presented and compared together with their competitiveness; the future of wind energy and cogeneration and the prospective of the renewal of nuclear plants at the 2010 horizon are also addressed

    Indian experience pertaining to investment and generation costs of nuclear power stations is reviewed. The causes of investment cost increases are analysed and the increases are apportioned to escalation, design improvements and safety related adders. The paper brings out the fact that PHWR investment costs in India compare favourably with those experienced in developed countries in spite of the fact that the programme and the unit size are relatively much smaller in India. It brings out that in India at current prices a nuclear power station located over 800 km from coal reserves and operating at 75% capacity factor is competitive with thermal power at 60% capacity factor.

    Full Text Available Great concern has been demonstrated by different aeronautic operators about the effects of electromagnetic interference in avionics and electronic equipments of airplanes, due to the use of portable electronic devices (PEDs, which can be easily carried by the passengers. Among the suspect devices, there are laptops and palmtops, audio recorders and reproducers, electronic games and toys, laser pointers, cell phones, communication radios and pagers. Uncouplings or automatic pilot deviations, mistaken indications in displays and, even, the unadverted disconnection of the avionics or variations not commanded in the control surfaces are flaws attributed to these devices. In spite of suffering critics, several regulation agencies in aeronautics, all over the world, have prohibited the use of these portable devices, specially in the critical phases of the flight – landing and take off. Nevertheless, it’s getting bigger the passengers desire of using, uninterruptely, laptops and cell phones, what makes necessary the adoption of safety procedures to satisfy this demand. Besides the concern over these dangerous effects, there are yet, doubts over the topic, and, therefore, it’s indicated the need of more investigations over these phenomenons. In this work, we relate the main accomplished experiments with the intent to clarify how the PEDs, more specifically the cell phones, cause an undesirable electromagnetic interference.

  18. Ventilation cost and air cleaning

    Science.gov (United States)

    Goodfellow, H. D.

    The components associated with the costs of the purchase of pollution control equipment are discussed. These include the capital cost to purchase the equipment and installation, and the costs incurred to operate the control device on an annual basis. Although the capital costs can represent a significant outlay of money, typically these costs are spread out over the life of the equipment. In general, this amortized cost is combined with the operating cost and is referred to as an 'annualized cost'. The annualized cost is a commonly used indicator to demonstrate the actual year to year cost that the equipment and operation will represent. Values and methods used to estimate costs, typical cost indicators, and sources of computerized costing models are presented. A comparison of the capital cost expenditure required for a model case (a cement kiln operation), using three control device alternatives is made.

The group did not consider that its purpose was to make technical judgements on proposed systems, but to develop methods for making reasonable cost estimates of these systems. Such estimates will, it is hoped, provide material for systems studies, will help in guiding research and development efforts by identifying ''high-leverage'' subsystems (areas that account for a significant part of total system cost and that might be reduced in cost by further technical development) and to begin to provide data to aid in an eventual decision on the optimum type of accelerator for heavy-ion fusion

The COST 516 Tribology Symposium took place in Espoo, Finland from 14th to 15th May 1998. This was the first Symposium of the COST 516 Tribology action. The large number of research contributions at the Symposium, altogether almost SO, and their scientific and technical level, is an indication of the importance and significance of tribology research. The symposium proceedings contain papers in a wide variety of subjects, covering the three categories of the COST 516 Tribology action, namely Grease lubrication (GRIT), Tribology of renewable environmentally adapted lubricants (REAL) and Coatings and surface treatments (CAST).

    AbstractWe forge linkages between the economics of property rights (Coase, Demsetz,Cheung, Barzel) and strategic management. Property rights to resources consistof the rights to consume, obtain income from, and alienate these resources.Transaction costs are the costs of exchanging, protecting...... and capturing propertyrights. We clarify the key role of transaction costs with respect to understandingvalue creation and the limitations and opportunities of strategizing relative tocompetitive forces. The economics of property rights identifies new sources ofvalue creation (i.e., reducing the dissipation...... caused by transaction costs), andnew types of resources (i.e., capture and protection capabilities), clarifies the roleof contracting in the exercise of market power, and suggests that `strategizing'and `economizing' perspectives are related to a larger extent than is normallyrecognized.

In a model of industry location with endogenous transaction costs that seeks to replicate features from the machinery industry, we show how and under which conditions a decline in transport costs can lead to an increase in the total cost of trade. The subtle relationship between (endogenous) transport costs and the sensitivity of trade to distance is also explored.

    Different methods of calculating the real power cost in the USA taking account of damage brought to the environment, public health expenses etc., are considered. Application of complex methods allowing one to directly determine the costs linked with ecology has shown that the most expensive power is generated at the new NPPs and thermal plants using coal. Activities on power saving and increasing the capacity of the existing hydroelectrotechnical equipment are considered to be the most effective from the viewpoint of expenses

    COST is an intergovernmental framework for European Cooperation in Science and Technology, allowing the coordination of nationally-funded research on a European level. COST contributes to reducing the fragmentation in European research investments and opening the European Research Area to cooperation worldwide. COST is specifically designed to network researchers mainly within the European Union that work on a specific topic. This COST BM0607 Action on cancer therapy using innovative targeting nanomedicines is highly multidisciplinary: nuclear medicine physicians, clinical oncologists, surgeons, physicists, radiobiologists, (in)organic chemists, radiochemists, radiopharmacists, pathologists and scientists from biomics participate in it. They define innovative new targets for cancer therapy, develop lead compounds and new radiolabelled ligands as vectors, perform molecular imaging and biologic testing, develop improved software and protocols for dosimetric calculations and select new vectors for early human use. Within the COST BM0607 more than 100 scientists from 21 countries are participating to work within 5 different working groups. Working group 1 works on the establishment of Database on Molecular Targets for Targeted Radionuclide Therapy, working group 2 deals with the development and improvement of chemistry related to new molecules for targeted radionuclide therapy. Working group 3 is dedicated to dosimetry aspects, whereas working group 4 tries to optimize the use of new radionuclides for therapy from cyclotron, reactor and generator production. Finally, working group 5 has the aim to bring together research related to pharmacology and small animal imaging with new tracers for targeted radionuclide therapy. COST thereby organizes annual meetings of the whole group and in between dedicated meetings of the working groups. Besides organizing meetings one aim of COST is additionally to promote young researchers where short term scientific missions (STSM) are

    The cost of picowave processing of food, i.e., exposing food to x-rays, gamma-rays and fast electrons from electron accelerators, is calculated as a function of the type of source, the dose absorbed, the rate of throughput, as well as the annual throughput. When the annual throughput is in excess of 10,000 tons per year the costs are usually between 1 and 10 cent per kg. (author). 33 refs, 12 figs, 22 tabs

As análises dos compostos voláteis foram feitas através de cromatografia gasosa e a avaliação sensorial dos destilados foi efetuada pelo grupo de degustação da Embrapa Uva e Vinho. Os resultados mostraram que o SO2 favoreceu a formação de etanal nas cultivares estudadas. Observou-se também um aumento na soma dos álcoois superiores em função do SO2, exceto para o destilado da cv. Isabel. Constatou-se que o destilado de Isabel se caracterizou por apresentar teor mais elevado de metanol e mais baixo de 1-propanol, possivelmente devido ao sistema de vinificação. O destilado de Isabel, juntamente com o de Couderc 13, apresentou teores mais baixos de 2-metil-1-propanol, 3-metil-1-butanol e da soma dos álcoois superiores.

    2012-03-01

    The future costs for dismantling, decommissioning and handling of associated radioactive waste of nuclear installations represents substantial liabilities. It is the generations that benefits from the use of nuclear installations that shall carry the financial burden. Nuclear waste programmes have occasionally encountered set-backs related to the trust from society. This has resulted in delayed, redirected or halted activities, which has the common denominator of costs increases. In modern democratic countries, information sharing, knowledge transfer and open communication about costs for the management of radioactive waste are prerequisites for the task to develop modern methods for public participation and thus to develop well-founded and justified confidence for further development of nuclear energy. Nuclear and radiation safety Authorities have a clear role to provide unbiased information on any health, safety, financial and environmental related issues. This task requires a good understanding of the values and opinion of the public, and especially those of the younger generation

  1. Underestimation of Project Costs

    Science.gov (United States)

    Jones, Harry W.

    2015-01-01

    Large projects almost always exceed their budgets. Estimating cost is difficult and estimated costs are usually too low. Three different reasons are suggested: bad luck, overoptimism, and deliberate underestimation. Project management can usually point to project difficulty and complexity, technical uncertainty, stakeholder conflicts, scope changes, unforeseen events, and other not really unpredictable bad luck. Project planning is usually over-optimistic, so the likelihood and impact of bad luck is systematically underestimated. Project plans reflect optimism and hope for success in a supposedly unique new effort rather than rational expectations based on historical data. Past project problems are claimed to be irrelevant because "This time it's different." Some bad luck is inevitable and reasonable optimism is understandable, but deliberate deception must be condemned. In a competitive environment, project planners and advocates often deliberately underestimate costs to help gain project approval and funding. Project benefits, cost savings, and probability of success are exaggerated and key risks ignored. Project advocates have incentives to distort information and conceal difficulties from project approvers. One naively suggested cure is more openness, honesty, and group adherence to shared overall goals. A more realistic alternative is threatening overrun projects with cancellation. Neither approach seems to solve the problem. A better method to avoid the delusions of over-optimism and the deceptions of biased advocacy is to base the project cost estimate on the actual costs of a large group of similar projects. Over optimism and deception can continue beyond the planning phase and into project execution. Hard milestones based on verified tests and demonstrations can provide a reality check.

    International Nuclear Information System (INIS)

    1975-01-01

    A critical review of the cost benefit analysis is given for the LMFBR-type reactor development program given in an environmental impact statement of AEC. Several methodological shortcomings are signalled. As compared with a HTGR-type/LWR-type mix of reactors the LMFBR-type reactor will not be competitive until the U 3 O 8 prices reach a level of $ 50/lb which is not likely to happen before the year 2020. It is recommended to review the draft of the ZEC document and include timing as one of the issues. Deferal of the LMFBR-type reactor development program if necessary will not be intolerably costly

    The structure of capital costs during NPP construction in Canada is considered. Capital costs comprise direct costs (cost of the ground and ground rights, infrastructure, reactor equipment, turbogenerators, electrotechnical equipment, auxiliary equipment), indirect costs (construction equipment and services, engineering works and management services, insurance payments, freight, training, operating expenditures), capital per cents for the period of construction and cost of heavy water storages. It proceeds from the analysis of the construction cost structure for a NPP with the CANDU reactor of unit power of 515, 740 and 880 MW, that direct costs make up on the average 62%

    PRICE H was introduced into the JPL cost estimation tool set circa 2003. It became more available at JPL when IPAO funded the NASA-wide site license for all NASA centers. PRICE H was mainly used as one of the cost tools to validate proposal grassroots cost estimates. Program offices at JPL view PRICE H as an additional crosscheck to Team X (JPL Concurrent Engineering Design Center) estimates. PRICE H became widely accepted ca, 2007 at JPL when the program offices moved away from grassroots cost estimation for Step 1 proposals. PRICE H is now one of the key cost tools used for cost validation, cost trades, and independent cost estimates.

  7. Honest signalling with costly gambles.

    Science.gov (United States)

    Meacham, Frazer; Perlmutter, Aaron; Bergstrom, Carl T

    2013-10-06

    Costly signalling theory is commonly invoked as an explanation for how honest communication can be stable when interests conflict. However, the signal costs predicted by costly signalling models often turn out to be unrealistically high. These models generally assume that signal cost is determinate. Here, we consider the case where signal cost is instead stochastic. We examine both discrete and continuous signalling games and show that, under reasonable assumptions, stochasticity in signal costs can decrease the average cost at equilibrium for all individuals. This effect of stochasticity for decreasing signal costs is a fundamental mechanism that probably acts in a wide variety of circumstances.

    2009-01-01

    This study quantified the lifetime costs of cerebral palsy (CP) in a register-based setting. It was the first study outside the US to assess the lifetime costs of CP. The lifetime costs attributable to CP were divided into three categories: health care costs, productivity costs, and social costs...... in 2000. The prevalence of CP in eastern Denmark was approximately 1.7 per 1000. Information on productivity and the use of health care was retrieved from registers. The lifetime cost of CP was about euro860 000 for men and about euro800 000 for women. The largest component was social care costs......, particularly during childhood. A sensitivity analysis found that alterations in social care costs had a small effect, whereas lowering the discount rate from 5 to 3 per cent markedly increased total lifetime costs. Discounting decreases the value of costs in the future compared with the present. The high...

    Power towers are capable of producing solar-generated electricity and hydrogen on a large scale. Heliostats are the most important cost element of a solar power tower plant. Since they constitute {approx} 50% of the capital cost of the plant it is important to reduce heliostat cost as much as possible to improve the economic performance of power towers. In this study we evaluate current heliostat technology and estimate a price of $126/m{sup 2} given year-2006 materials and labor costs for a deployment of {approx}600 MW of power towers per year. This 2006 price yields electricity at $0.067/kWh and hydrogen at $3.20/kg. We propose research and development that should ultimately lead to a price as low as $90/m{sup 2}, which equates to $0.056/kWh and $2.75/kg H{sup 2}. Approximately 30 heliostat and manufacturing experts from the United States, Europe, and Australia contributed to the content of this report during two separate workshops conducted at the National Solar Thermal Test Facility.

    A polycrystalline Si thin film formation technology is developed, which uses the flux process in which a reaction occurs between the target crystal and a flux component which is eutectic. Using this process, a crystal grain relatively large in diameter is obtained at a relatively low temperature. This method is now attracting attention as one of the technologies for producing crystalline Si film for use in thin-film polycrystalline Si solar cells. Especially when Al is used for flux, since Al is automatically doped into the target crystalline Si film, it is expected that the resulting film will serve as the ground for a photoactive layer provided with the BSF (back surface field) function which is important for the improvement of solar cell efficiency. A polycrystalline Si thin film is formed on a 2cm times 2cm-large glass substrate at a temperature not higher than 600 degrees C. It is recognized that films selectively oriented towards the (111) or (100) plane are acquired when other processes are employed. It is expected that the said Al-doped film provides a ground on which a BSF function-provided photoactive layer will be formed. (NEDO)

    Cost stickiness occurs when costs decrease less when sales fall than they increase when sales rise. Prior literature provides both economic and agency explanations of sticky costs. Our study tackles this cost behaviour from a managerial behavioural perspective. We predict and find that cost stickiness is greater when firms are managed by overconfident CEOs. The results are consistent with the notion that overconfident CEOs are more likely to exhibit an optimistic bias and tend to be overly po...

  7. Nuclear power production costs

    International Nuclear Information System (INIS)

    Erramuspe, H.J.

    1988-01-01

    The economic competitiveness of nuclear power in different highly developed countries is shown, by reviewing various international studies made on the subject. Generation costs (historical values) of Atucha I and Embalse Nuclear Power Plants, which are of the type used in those countries, are also included. The results of an international study on the economic aspects of the back end of the nuclear fuel cycle are also reviewed. This study shows its relatively low incidence in the generation costs. The conclusion is that if in Argentina the same principles of economic racionality were followed, nuclear energy would be economically competitive in the future, as it is today. This is of great importance in view of its almost unavoidable character of alternative source of energy, and specially since we have to expect an important growth in the consumption of electricity, due to its low share in the total consumption of energy, and the low energy consumption per capita in Argentina.

  9. Phenotypic plasticity, costs of phenotypes, and costs of plasticity

    DEFF Research Database (Denmark)

    Callahan, Hilary S; Maughan, Heather; Steiner, Uli

    2008-01-01

    Why are some traits constitutive and others inducible? The term costs often appears in work addressing this issue but may be ambiguously defined. This review distinguishes two conceptually distinct types of costs: phenotypic costs and plasticity costs. Phenotypic costs are assessed from patterns...... of covariation, typically between a focal trait and a separate trait relevant to fitness. Plasticity costs, separable from phenotypic costs, are gauged by comparing the fitness of genotypes with equivalent phenotypes within two environments but differing in plasticity and fitness. Subtleties associated with both...... types of costs are illustrated by a body of work addressing predator-induced plasticity. Such subtleties, and potential interplay between the two types of costs, have also been addressed, often in studies involving genetic model organisms. In some instances, investigators have pinpointed the mechanistic...

    A tool is presented to quantify the risks of geothermal projects, the Geothermal Probabilistic Cost Model (GPCM). The GPCM model is used to evaluate a geothermal reservoir for a binary-cycle electric plant at Heber, California. Three institutional aspects of the geothermal risk which can shift the risk among different agents are analyzed. The leasing of geothermal land, contracting between the producer and the user of the geothermal heat, and insurance against faulty performance are examined. (MHR)

    2012-10-01

    The current study examined costs experienced by victims of completed rape (n=49) and attempted sexual assault (n=91) using quantitative analyses of 13 domains: health, self-esteem, self-perceived attractiveness, self-perceived mate value, family relationships,work life, social life, social reputation, sexual reputation, desire to have sex, frequency of sex, enjoyment of sex, and long-term, committed relationships. Women also provided descriptive accounts of their experiences, and we used these to illustrate the costs in the victims' own words.Compared to victims of an attempted sexual assault, victims of a completed rape reported significantly more negative outcomes in 11 of the 13 domains. The most negatively affected domains were self-esteem, sexual reputation, frequency of sex, desire to have sex, and self-perceived mate value. Although victims of rape experienced more negative effects than victims of attempted sexual assault,both groups of victims reported negative effects in every domain.Discussion focuses on the implications of the differing degrees and patterns of the costs of attempted and completed sexual victimization.

  15. Radiation: cost or benefit?

    International Nuclear Information System (INIS)

    Crouch, D.

    1988-01-01

    In a previous issue of SCRAM it was argued that the apparent increased incidence of child leukaemia around nuclear power stations could have been caused by radioactive discharges into the environment. The National Radiological Protection Board (NRPB) claim that the known levels of contamination could not be responsible for the observed cancer rates. NRPB estimates of radiation risk are, however, considered to be underestimates. The NRPB is criticised for its study of the Sellafield workforce which excluded ex-employees and which revealed, when a statistical mistake was put right, a significant excess of myeloma amongst the Windscale workforce. The radiation protection philosophy of the NRPB is based on a cost benefit analysis which balances the cost of protection against the benefits of power generation. Criticism is made of NRPB, not only for ignoring long-term risks and costs but also for suggesting that some levels of radiation exposure are acceptable. The Board is also accused of not being independent of the nuclear industry. (UK)

Cost of anaesthesiology represent defined measures to determine a precise profile of expenditure estimation of surgical treatment, which is important regarding planning of healthcare activities, prices and budget. Objective. In order to determine the actual value of anaestesiological services, we started with the analysis of activity based costing (ABC analysis. Methods. Retrospectively, in 2005 and 2006, we estimated the direct costs of anestesiological services (salaries, drugs, supplying materials and other: analyses and equipment. of the Institute of Anaesthesia and Resuscitation of the Clinical Centre of Serbia. The group included all anesthetized patients of both sexes and all ages. We compared direct costs with direct expenditure, “each cost object (service or unit” of the Republican Health-care Insurance. The Summary data of the Departments of Anaesthesia documented in the database of the Clinical Centre of Serbia. Numerical data were utilized and the numerical data were estimated and analyzed by computer programs Microsoft Office Excel 2003 and SPSS for Windows. We compared using the linear model of direct costs and unit costs of anaesthesiological services from the Costs List of the Republican Health-care Insurance. Results. Direct costs showed 40% of costs were spent on salaries, (32% on drugs and supplies, and 28% on other costs, such as analyses and equipment. The correlation of the direct costs of anaestesiological services showed a linear correlation with the unit costs of the Republican Healthcare Insurance. Conclusion. During surgery, costs of anaesthesia would increase by 10% the surgical treatment cost of patients. Regarding the actual costs of drugs and supplies, we do not see any possibility of costs reduction. Fixed elements of direct costs provide the possibility of rationalization of resources in anaesthesia.

  17. Systematization of Cost Factors for Cost Management at Industrial Enterprises

    Directory of Open Access Journals (Sweden)

    N. Y.

    2017-12-01

    Full Text Available Identification and structuring of factors determining the cost level has significant importance in cost analysis and control. Cost factors need to be systematized for more effective cost management. The objective of the study is to identify and structure the factors with impact on the enterprise costs. The external and internal factors with impact on the enterprise costs in industry are highlighted. For cost management purposes, it is proposed to group the cost factors into the two categories: structural and functional. The essence of structural and functional factors is shown; a classification of functional factors is given. The effect of a structural factor such as products range (complexity is illustrated. As the factor of complexity, combined with cost analysis systems and innovative tools of analysis (ABC and XYZ methods, has been increasingly in focus of analysts, three problems are described which, once dealt with, will enable ABC method to fit into the cost management system. The importance of another structural factor of costs, technology selection, in cost management is shown. The analysis allows for the following conclusions: for purposes of current cost management, including one based on operational analysis, the output needs to be addressed as the central factor determining the cost level; in the strategic perspective, an enterprise needs to concentrate on calculating the costs for the structural alternatives that are supposed to determine its competitive position; for cost management purposes, the cost factors should be broken into two categories, structural and functional; a specific management system exists for each cost factor, which is greatly important for the positioning of an enterprise.

  19. THE COST OF PRODUCTION UNDER DIRECT COSTING AND ABSORPTION COSTING – A COMPARATIVE APPROACH

    Directory of Open Access Journals (Sweden)

    Bunea-Bontaş Cristina Aurora

    2013-04-01

    Full Text Available Managerial accounting has an important role in strategic management of a company, being designed especially for managers, in order to optimise their decision regarding operating activities. One of the objectives of managerial accounting is the cost calculation, for measuring inventory costs, and the costs and profitability of products and services. Cost calculation systems can vary in terms of which costs are assigned to cost objects, two significant calculation systems being adopted by the costing theory: full cost accounting, which includes all costs of production as product costs, and partial cost accounting, which includes only those costs that vary with output. This article provides a comparative approach regarding the differences between the calculation of the cost of production under direct costing and absorption costing. It also examines the implication of using each of these calculation systems on the financial position and financial performance of the companies reported on the statement of financial position and the income statement. Finally, the advantages of using direct costing for internal reporting are discussed, considering that this method is not acceptable for external reporting to stockholders and other external users.

    Twenty-two hundred women in Orange County, California, took part in a low-cost mammography screening project sponsored by the American Cancer Society and the KCBS-TV. Patients were followed up by telephone and questioned about actual costs incurred as a result of screening mammography, including costs of repeated and follow-up mammograms, US examinations and surgical consultations. The total number of biopsies, cancers found, and the costs involved were investigated. The authors' results suggest that particularly in centers with a high positive call rate, the cost of screening mammograms accounts for only a small proportion of the medical costs

    A study has been made by Scandpower A/S of the costs of nuclear power in Sweden. It is based on the known costs of existing Swedish nuclear power plants and forecasts of the expected costs of the Swedish nuclear power programme. special emphasis has been put on the fuel cycle costs and future costs of spent fuel processing, waste disposal and decommissioning. Costs are calculated in 1978 Swedish crowns, using the retail price index. An actual interest rate of 4% is used, with depreciation period of 25 years and a plant lifetime of 30 years. Power production costs are estimated to be about 7.7 oere/kWh in 1978, rising to 10.5 oere/kWh in 2000. The cost is distributed with one third each to capital costs, operating costs and fuel costs, the last rising to 40% of the total at the end of the century. The main single factor in future costs is the price of uranium. If desired, Sweden can probably be self-sufficient in uranium in 2000 at a lower cost than assumed here. National research costs which, in Scandpower's opinion, can be debited to the commercial nuclear power programme are about 0.3 oere/kWh. (JIW)

    Successful commercialization of fusion energy requires economic viability as well as technical and scientific feasibility. To assess economic viability, we have conducted a pre-conceptual level evaluation of LIFE economics. Unit costs are estimated from a combination of bottom-up costs estimates, working with representative vendors, and scaled results from previous studies of fission and fusion plants. An integrated process model of a LIFE power plant was developed to integrate and optimize unit costs and calculate top level metrics such as cost of electricity and power plant capital cost. The scope of this activity was the entire power plant site. Separately, a development program to deliver the required specialized equipment has been assembled. Results show that LIFE power plant cost of electricity and plant capital cost compare favorably to estimates for new-build LWR's, coal and gas - particularly if indicative costs of carbon capture and sequestration are accounted for.

    The reasons why residential customers of public power utilities paid less for power than private sector customers is discussed. Residential customers of investor-owned utilities (IOU's) paid average rates that were 28% above those paid by customers by possibly owned systems during 1990. The reasons for this disparity are that management costs faced by public power systems are below those of private power companies, indicating a greater efficiency of management among public power systems, and customer accounts expenses averaged $33.00 per customer for publicly owned electric utilities compared to $39.00 per customer for private utilities

    2017-03-28

    To date, there has been no standard method or tool to analyze the installed and operational costs for distributed wind turbine systems. This report describes the development of a classification system, or taxonomy, for distributed wind turbine project costs. The taxonomy establishes a framework to help collect, sort, and compare distributed wind cost data that mirrors how the industry categorizes information. The taxonomy organizes costs so they can be aggregated from installers, developers, vendors, and other sources without losing cost details. Developing a peer-reviewed taxonomy is valuable to industry stakeholders because a common understanding the details of distributed wind turbine costs and balance of station costs is a first step to identifying potential high-value cost reduction opportunities. Addressing cost reduction potential can help increase distributed wind's competitiveness and propel the U.S. distributed wind industry forward. The taxonomy can also be used to perform cost comparisons between technologies and track trends for distributed wind industry costs in the future. As an initial application and piloting of the taxonomy, preliminary cost data were collected for projects of different sizes and from different regions across the contiguous United States. Following the methods described in this report, these data are placed into the established cost categories.

  15. Reducing maintenance costs

    2002-01-01

    The increasingly more expensive maintenance measures, cuts in the cost budget, and the loss of know-how on the part of vendors all require a change of policy with respect to maintenance concepts of the part of operators. This also applies to the existing valve concepts, the drives included. Under these aspects, the current drive, which is self-actuated and actuated by outside media, for a parallel-plate valve of a nomial width of 700 was reconsidered. The effort served to reduce maintenance costs and, at the same time, simplify the drive concept as well as cut back on the number of in-service inspections. Moreover, the number of active components were to be minimized and installation conditions in the plant were to be improved. When the boundary conditions to be observed with respect to process technology had been laid down, the competent technical department developed a concept of modification of the drive. A major constituent part was the demonstration of the functioning capability of the new drive under accident conditions. It was achieved mainly by an analytical approach. In the resultant drive concept, the same control valves are employed to actuate a driving cylinder by means of self-actuation or by an outside medium as a function of pressure. (orig.) [de

    2012-03-01

    Explaining the evolution of sex is challenging for biologists. A 'twofold cost' compared with asexual reproduction is often quoted. If a cost of this magnitude exists, the benefits of sex must be large for it to have evolved and be maintained. Focusing on benefits can be misleading, as this sidelines important questions about the cost of sex: what is the source of the twofold cost: males, genome dilution or both? Does the cost deviate from twofold? What other factors make sex costly? How should the costs of sex be empirically measured? The total cost of sex and how it varies in different contexts must be known to determine the benefits needed to account for the origin and maintenance of sex. Copyright © 2011 Elsevier Ltd.

    The question of wind integration cost has received much attention in the past several years. The methodological challenges to calculating integration costs are discussed in this paper. There are other sources of integration cost unrelated to wind energy. A performance-based approach would be technology neutral, and would provide price signals for all technology types. However, it is difficult to correctly formulate such an approach. Determining what is and is not an integration cost is challenging. Another problem is the allocation of system costs to one source. Because of significant nonlinearities, this can prove to be impossible to determine in an accurate and objective way.

    Conventional cost accounting assumes that the relation between cost and volume is symmetric for volume increases and decreases. We test an alternative model where costs increase more when activity rises than they decrease when activity falls by an equivalent amount. We find, for a sample of Brazilian firms that selling, general, and administrative costs increase 0.59% per 1% increase in sales but decrease only 0.32% per 1% decrease in sales. We test several hypotheses about the properties of ...

    Taking Epsteins testing theory as a basis, premisses are formulated for the selection of cost-optimized reliability inspection plans. Using an example, the expected testing costs and inspection time periods of various inspection plan types, standardized on the basis of the exponential distribution, are compared. It can be shown that sequential reliability tests usually involve lower costs than failure or time-fixed tests. The most 'costly' test is to be expected with the inspection plan type NOt. (orig.)

    Full Text Available Switching cost is defined as possible costs that customers may encounter when they want to change the firm they buy service, and an important subject in terms of accounting services. Particularly, small business entrepreneurs’ not having knowledge about accounting procedures, and sharing private information with accounting firms make switching costs more important for accounting services. Thus, the aim of this study is to investigate the concept of switching costs (relational cost, procedural cost and financial cost, its determinants (perceived service quality, service importance, and service failures, and consequences (re-purchasing, and recommen ding to others. Theresearch was conducted on small business entrepreneurs in down-town of Balıkesir in Turkey. Total 405 small business entrepreneur owners were interviewed. According to results of the study, perceived service quality positively affects all dimensions of switching costs, significance of service positively affects procedural and relational costs, and service failures negatively affect procedural and relational costs. The results showed that while procedural and relational costs positively affect re-purchasing and recommending to others variables, financial cost did not have any effect on these variables.

    Full Text Available The Danish Ministry of Culture has funded a project to set up a model for costing preservation of digital materials held by national cultural heritage institutions. The overall objective of the project was to increase cost effectiveness of digital preservation activities and to provide a basis for comparing and estimating future cost requirements for digital preservation. In this study we describe an activity-based costing methodology for digital preservation based on the Open Archice Information System (OAIS Reference Model. Within this framework, which we denote the Cost Model for Digital Preservation (CMDP, the focus is on costing the functional entity Preservation Planning from the OAIS and digital migration activities. In order to estimate these costs we have identified cost-critical activities by analysing the functions in the OAIS model and the flows between them. The analysis has been supplemented with findings from the literature, and our own knowledge and experience. The identified cost-critical activities have subsequently been deconstructed into measurable components, cost dependencies have been examined, and the resulting equations expressed in a spreadsheet. Currently the model can calculate the cost of different migration scenarios for a series of preservation formats for text, images, sound, video, geodata, and spreadsheets. In order to verify the model it has been tested on cost data from two different migration projects at the Danish National Archives (DNA. The study found that the OAIS model provides a sound overall framework for the cost breakdown, but that some functions need additional detailing in order to cost activities accurately. Running the two sets of empirical data showed among other things that the model underestimates the cost of manpower-intensive migration projects, while it reinstates an often underestimated cost, which is the cost of developing migration software. The model has proven useful for estimating the

    The categorization and accounting methods described in this paper provide a common format that can be used to assess the economic character of magnetically confined fusion reactor design concepts. The format was developed with assistance from the fusion economics community, thus ensuring that the methods meet with the approval of potential users. The format will aid designers in the preparation of design concept cost estimates and also provide policy makers with a tool to assist in appraising which design concepts may be economically promising. Adherence to the format when evaluating prospective fusion reactor design concepts will result in the identification of the more promising concepts, thus enabling the fusion power alternatives with better economic potential to be quickly and efficiently developed

    Recent resource assessments conducted by the United States Department of Energy have identified significant opportunities for expanding hydropower generation through the addition of power to non-powered dams and on undeveloped stream-reaches. Additional interest exists in the powering of existing water resource infrastructure such as conduits and canals, upgrading and expanding existing hydropower facilities, and the construction new pumped storage hydropower. Understanding the potential future role of these hydropower resources in the nation’s energy system requires an assessment of the environmental and techno-economic issues associated with expanding hydropower generation. To facilitate these assessments, this report seeks to fill the current gaps in publically available hydropower cost-estimating tools that can support the national-scale evaluation of hydropower resources.

  20. The Cost of Conscience.

    2017-01-01

    The spread of demands by physicians and allied health professionals for accommodation of their private ethical, usually religiously based, objections to providing care of a particular type, or to a particular class of persons, suggests the need for a re-evaluation of conscientious objection in healthcare and how it should be regulated. I argue on Kantian grounds that respect for conscience and protection of freedom of conscience is consistent with fairly stringent limitations and regulations governing refusal of service in healthcare settings. Respect for conscience does not entail that refusal of service should be cost free to the objector. I suggest that conscientious objection in medicine should be conceptualized and treated analogously to civil disobedience.

  1. Stranded costs and exit fees

    International Nuclear Information System (INIS)

    2002-01-01

    The New Brunswick Market Design Committee has been directed to examine the issue of stranded costs since it is a major component of restructuring within the electricity sector. When regulated monopolies are faced with competition, they could find that some of their embedded costs cannot be recovered. These costs are referred to as stranded costs. Common sources include large capital investments in uneconomic plants or expensive power purchase contracts or fuel supply contracts. In general, stranded costs do not include gains or losses associated with normal business risks experienced by regulated utilities. This report presents recommendations for mitigation of stranded costs, valuation methodologies and cost-recovery mechanisms. It also presents a summary of experience with stranded costs in other jurisdictions such as California, Rhode Island, Pennsylvania and Ontario. Stranded costs are often recovered through an obligatory charge on all customers, particularly in jurisdictions where retail competition exists. In the New Brunswick market, however, the only customers who can create stranded costs are those eligible to choose their own suppliers. It is argued that since most customers will not have a choice of electricity suppliers, they cannot generate stranded costs and therefore, should not have to pay costs stranded by others. A method to quantify stranded costs is presented, along with a review of transmission-related stranded costs in New Brunswick. Expansion of self-generation in New Brunswick could strand transmission assets. Currently, self-generators only contribute a small amount to fixed charges of the transmission system. However, under new recommended tariffs, the amount could increase. It is likely that the net amount of stranded transmission costs will not be large. 2 refs., 1 fig

    1. Our study consists on analysing annual technical operating costs (excluding professional fees) of computed tomography and extracorporeal lithotripsy in order to define a pricing system able to provide proper reimbursements of technical costs for costly equipment. 2. Economic and utilization data have been collected from physicians responsible for facilities and from equipment current manufacturers. Annual charges are assessed in function of annual volume of procedures. 3. Definition of mean costs (total mean cost, mean cost of one more procedure) and mean cost distribution analysis according to annual volume of procedures lead to propose a method for financing costly technical medical activities based on a two-price rate: until a defined number of procedures is reached, a full-rate reimbursement is applied and then, it is replaced by a reduced-rate reimbursement. 4. Such a pricing system is easy to manage and allows to fit annual technical receipts to annual technical expenditure on a wide range of patient procedure volume.

  3. Managing clinical grant costs.

    Glass, Harold E; Hollander, Karen

    2009-05-01

    The rapidly increasing cost of pharmaceutical R&D presents a major challenge for the industry. This paper examines one aspect of that spending, clinical grants, and presents ways that pharmaceutical companies can best manage those expenditures. The first part of the paper examines the role of clinical grant payments as a motivation for clinical trial participation. The second part outlines a number of current management practices for controlling clinical grant costs. Financial compensation is an important matter for many physicians conducting clinical trials, especially those in office-based practices and those conducting phase 4 clinical trials. Since financial considerations are important to most types of investigators, and there is no compelling evidence that paying at high rates insures timely performance or quality data, companies engaging clinical investigators must manage their clinical grant funds as effectively as possible. Sound financial management requires that clinical development professionals appreciate the complex relationship between the pharmaceutical company and the physicians who serve as clinical investigators on that company's clinical trials. Sensible financial management of clinical grants also demands that sponsor companies get the most value for their clinical grant spending. Ultimately, good clinical grant management requires an attitude that combines good business sense with an understanding that pharmaceutical R&D strives to bring to market new drugs that can help patient populations around the world. Investigators are medical contractors in clinical trials, and while they are engaged in their vital research, they are a part of the research process that must be carefully budgeted and managed. Society, pharmaceutical companies, clinical investigators, and patients will reap the benefits of adequately budgeted, and well managed clinical grants.

    Full Text Available In this paper, an integrated approach based on Monte Carlo simulation and Six Sigma methodology is used to analyze the risk associated with a project's total cost. Monte Carlo simulation is applied to understand the variability in total cost caused by the probabilistic cost items. By Six Sigma methodology the range of variation of the project cost can be reduced by operating on the input factors with the greatest impact on total cost to cover the variation of 6 between the limits that were established in the design phase of Six Sigma.

  6. Maintenance cost models in deregulated power systems under opportunity costs

    In a centralized power system, the operator is responsible for scheduling maintenance. There are different types of maintenance, including corrective maintenance; predictive maintenance; preventive maintenance; and reliability-centred maintenance. The main cause of power failures is poor maintenance. As such, maintenance costs play a significant role in deregulated power systems. They include direct costs associated with material and labor costs as well as indirect costs associated with spare parts inventory, shipment, test equipment, indirect labor, opportunity costs and cost of failure. In maintenance scheduling and planning, the cost function is the only component of the objective function. This paper presented the results of a study in which different components of maintenance costs were modeled. The maintenance models were formulated as an optimization problem with single and multiple objectives and a set of constraints. The maintenance costs models could be used to schedule the maintenance activities of power generators more accurately and to identify the best maintenance strategies over a period of time as they consider failure and opportunity costs in a deregulated environment. 32 refs., 4 tabs., 4 figs

    There is a growing interest in carbon capture and storage (CCS) as a means of reducing carbon dioxide (CO2) emissions. However there are substantial uncertainties about the costs of CCS. Costs for pre-combustion capture with compression (i.e. excluding costs of transport and storage and any revenue from EOR associated with storage) are examined in this discussion paper for First-of-a-Kind (FOAK) plant and for more mature technologies, or Nth-of-a-Kind plant (NOAK). For FOAK plant using solid fuels the levelised cost of electricity on a 2008 basis is approximately 10 cents/kWh higher with capture than for conventional plants (with a range of 8-12 cents/kWh). Costs of abatement are found typically to be approximately US$150/tCO2 avoided (with a range of US$120-180/tCO2 avoided). For NOAK plants the additional cost of electricity with capture is approximately 2-5 cents/kWh, with costs of the range of US$35-70/tCO2 avoided. Costs of abatement with carbon capture for other fuels and technologies are also estimated for NOAK plants. The costs of abatement are calculated with reference to conventional SCPC plant for both emissions and costs of electricity. Estimates for both FOAK and NOAK are mainly based on cost data from 2008, which was at the end of a period of sustained escalation in the costs of power generation plant and other large capital projects. There are now indications of costs falling from these levels. This may reduce the costs of abatement and costs presented here may be 'peak of the market' estimates. If general cost levels return, for example, to those prevailing in 2005 to 2006 (by which time significant cost escalation had already occurred from previous levels), then costs of capture and compression for FOAK plants are expected to be US$110/tCO2 avoided (with a range of US$90-135/tCO2 avoided). For NOAK plants costs are expected to be US$25-50/tCO2. Based on these considerations a likely representative range of costs of abatement from CCS

    In order to identify whether it is better to build a gas plant, a nuclear plant or a wind farm, to identify the technology leading to the lowest KWh cost, to identify under which conditions nuclear production is profitable for a private investor, and to identify whether taking the dismantling cost and the waste storage cost into account modifies the nuclear competitiveness with respect to general interest, the author first discusses the different costs of the nuclear sector, their sensitivity to different factors. In a second part, he proposes a retrospective discussion of cost dynamics. Then, as nuclear technology seems characterized by always increasing costs, and as this trend may last, notably because of safety concerns, the author proposes an analysis of the poor competitiveness of nuclear with respect to its cost

    It is difficult to define the true cost of a burns injury, however there has always been a consensus that the costs associated with burns care are high. This study aims to achieve an accurate calculation of the cost of acute burns care in an Australian context. A retrospective review of 20 adult burn patients treated at our Centre was performed. An itemized price list was prepared based on items, services and equipment actually utilized in the care of burns patients. Case records were reviewed for a count of quantities to calculate costs for each item. Regression analysis was performed to produce a cost vs %TBSA curve for cost prediction. A cost breakdown was also performed for analysis of the most significant areas of expenditure and their trends with %TBSA. The cost calculated for an average adult burns patient was AU$71,056 (US$73,532). The total cost of all 20 patients was AU$2,449,112 (US$2,534,464). %TBSA injured was confirmed as the primary determinant of cost. Hospital length of stay, operative costs, dressings and staffing were found to be the most significant components of cost and increased most prominently with %TBSA. Compared to our findings, expenditure for prevention and education programs is minimal. There is limited conclusive evidence that changes in management protocols have had successful impact on the cost of burns treatment. Future progress in burns management may effect factors such as hospital length of stay, however until such changes, resource allocation should recognize the importance of prevention and its success at reduction of injury severity for real reductions in cost of burns care.

    Despite the wide-ranging financial and social burdens associated with schizophrenia, there have been few cost-of-illness studies of this illness in the UK. To provide up-to-date, prevalence based estimate of all costs associated with schizophrenia for England. A bottom-up approach was adopted. Separate cost estimates were made for people living in private households, institutions, prisons and for those who are homeless. The costs included related to: health and social care, informal care, private expenditures, lost productivity, premature mortality, criminal justice services and other public expenditures such as those by the social security system. Data came from many sources, including the UK-SCAP (Schizophrenia Care and Assessment Program) survey, Psychiatric Morbidity Surveys, Department of Health and government publications. The estimated total societal cost of schizophrenia was 6.7 billion pounds in 2004/05. The direct cost of treatment and care that falls on the public purse was about 2 billion pounds; the burden of indirect costs to the society was huge, amounting to nearly 4.7 billion pounds. Cost of informal care and private expenditures borne by families was 615 million pounds. The cost of lost productivity due to unemployment, absence from work and premature mortality of patients was 3.4 billion pounds. The cost of lost productivity of carers was 32 million pounds. Estimated cost to the criminal justice system was about 1 million pounds. It is estimated that about 570 million pounds will be paid out in benefit payments and the cost of administration associated with this is about 14 million pounds. It is difficult to compare estimates from previous cost-of-illness studies due to differences in the methods, scope of analyses and the range of costs covered. Costs estimated in this study are detailed, cover a comprehensive list of relevant items and allow for different levels of disaggregation. The main limitation of the study is that data came from a

    To evaluate costs, cost-efficiency and cost-effectiveness of integration of family planning into HIV services. Integration of family planning services into HIV care and treatment clinics. A cluster-randomized trial. Twelve health facilities in Nyanza, Kenya were randomized to integrate family planning into HIV care and treatment; six health facilities were randomized to (nonintegrated) standard-of-care with separately delivered family planning and HIV services. We assessed costs, cost-efficiency (cost per additional use of more effective family planning), and cost-effectiveness (cost per pregnancy averted) associated with the first year of integration of family planning into HIV care. More effective family planning methods included oral and injectable contraceptives, subdermal implants, intrauterine device, and female and male sterilization. We collected cost data through interviews with study staff and review of financial records to determine costs of service integration. Integration of services was associated with an average marginal cost of $841 per site and $48 per female patient. Average overall and marginal costs of integration were associated with personnel costs [initial ($1003 vs. $872) and refresher ($498 vs. $330) training, mentoring ($1175 vs. $902) and supervision ($1694 vs. $1636)], with fewer resources required for other fixed ($18 vs. $0) and recurring expenses ($471 vs. $287). Integration was associated with a marginal cost of $65 for each additional use of more effective family planning and $1368 for each pregnancy averted. Integration of family planning and HIV services is feasible, inexpensive to implement, and cost-efficient in the Kenyan setting, and thus supports current Kenyan integration policy.

  18. Social costs of transition

    Directory of Open Access Journals (Sweden)

    Pavlović Dušan

    2006-01-01

    Full Text Available The risk of political and economic transformation in Central and East Europe after 1990 was based on the presumption that the reforms will collapse when the citizens realize that the cost they have to pay for them is too high. The classical claim was that democracy will be destroyed by democratic means-namely, that the losers in the transition will vote the way back to the authoritarian regime. The article offers an explanation as to the regress to the authoritarian regime will not be a consequence of the economic reforms. The article is divided in six section. Section 1 considers the general context of the start of the economic transformation in the light of the debate about the choice between the expert government and the significance of democratic procedures for economic reforms. Section 2 defines the context of Serbia within which economic transformation started out after 2000. Sections 4-5 consider economic policy of the two post-Milosevic government. The major finding is that it was the economic policy that was highly socially sensible that prevented social uprising and undermining democracy by democratic means. Section 6 concludes by applying the concept of equilibrium of partial reforms.

    Full Text Available Globalization has both costs and benefits. In this paper we would focus upon one of the damages of globalization to China. It is said that inward FDI replaces local domestic capabilities in import-substitution countries. In the case of China the Chinese domesticindustries are lacking technological innovations because of heavy reliance upon FDI. Most of the Chinese exports of electronics are carried under FDI whereas in Korea and Japan they are indigenously-driven. In 1960s, Korea received foreign capital in the formof loans but it denied the entrance to foreign firms. Korea followed the Japanese model by quickly mastering the foreign technology rather than letting foreign firms to establish local subsidiaries and to decide the speed and scope of technology diffusion. Korea andJapan adopted the techno-nationalist policies for attaining autonomous domestic innovated industries. By restricting FDI, Korea and Japan were able to maintain their management independent of Multi-National Companies. In this paper we would try to analyze that whether China’s policy of reliance upon FDI is a success or a debacle by comparing it with Korea and Japan.

    This paper aims to address two questions: First, what is the real cost of meat to society if taking into account the environmental costs arising throughout the product life cycle; and second, whether and how the environmental costs related to meat production can be reduced. In addressing the issues......, we use pig meat production in the EU as a case study. The environmental costs of meat are displayed first as characterized results at different midpoint categories e.g. global warming, nature occupation, acidification, eutrophication, ecotoxicity, etc., and then aggregated into a single score using...... conversion factors available from the Stepwise2006 method. Overall, the environmental costs of producing conventional pig meat are estimated to be 1.9 EUR per kg, which are of even larger size than the private costs of 1.4 EUR. In decreasing order of importance, nature occupation has been found...

    This chapter investigates the concept of the ‘hidden costs’ of offshoring, i.e. unexpected offshoring costs exceeding the initially expected costs. Due to the highly undefined nature of these costs, we position our analysis towards the strategic responses of firms’ realisation of hidden costs. In......-by-doing process, where hidden costs motivate firms and their employees to search for new and better knowledge on how to successfully manage the organisation. We illustrate this thesis based on the case of the LEGO Group........ In this regard, we argue that a major response to the hidden costs of offshoring is the identification and utilisation of strategic mechanisms in the organisational design to eventually achieving system integration in a globally dispersed and disaggregated organisation. This is heavily moderated by a learning...

    2007-05-15

    In a way to reduce the external energy dependence, increasing also the investments in renewable energy sources and aiming for the concretization of the European renewable objectives, the Portuguese government defined a goal of 5100 MW of installed wind power, up to 2012. If the drawn objectives are accomplished, by 2010 the wind power share may reach values comparable to leading countries like Denmark, Germany or Spain. The Portuguese forecasts also indicate a reinforcement of the natural gas fired generation in particular through the use of the combined cycle technology, following the European tendency. This analysis sets out to evaluate the total generating cost of wind power and CCGT in Portugal. A life cycle cost analysis was conducted, including investment costs, O and M costs, fuel costs and external costs of emissions, for each type of technology. For the evaluation of the externalities ExternE values were used. The results show that presently the wind power production cost is higher than the CCGT one, at least from the strictly financial point of view. CCGT costs increase significantly when charges for externalities are included. However, they only reach levels higher than the equivalents for wind power for high externality costs estimations. This partially results from the low load factor of the wind farms in Portugal and also from the low emission levels of the gas fired technology used in the comparison. A sensitive analysis of the technical and economical parameters was also conducted. Particular attention was given to the natural gas prices due to the possible increase over time. The fuel escalation rate is the parameter that has larger effects on the final costs. It was verified that the total cost of wind plant is more influenced by the load factor than the total cost of CCGT. (au)

  11. An Insight Into the Two Costing Technique: Absorption Costing and Marginal Costing

    Directory of Open Access Journals (Sweden)

    Mariam Nawaz

    2013-02-01

    Full Text Available This paper will investigate the controversy that is innate between the two costing techniques; Absorption Costing and Marginal Costing and would throw light on which costing technique better serves its purpose in helping management for decision making process and if Marginal Costing technique is concluded as better technique then why it should not be used for external reporting purpose. This paper will only crystallize and highlight the issues descriptively and will not resolve the issues that are inherent between the two costing techniques. The unique thing about this paper is that it is in favor of treating fixed cost as product cost that is it is supporting the advocates of Absorption Costing Technique but it is against to consider profit as a function of production rather it believes that profit should only be considered as function of sales for stock valuation and to help management in decision making process that is, regarding this point it is supporting advocates of Marginal Costing.

  12. Electricity costs in liberalized market

    International Nuclear Information System (INIS)

    Barkans, J.; Junghans, G.

    2006-01-01

    In the liberalized electricity market the flexible demand determines the operation of power plants. Under market conditions the producers are forced to compete, and their power plants are normally loaded in order of increasing prices. The electricity costs consist of fixed and variable components, and the competition among producers simulates minimization of both the components. Considering the fixed costs (including maintenance, depreciation, capital costs and other permanent costs not depending on production) to be known, the total electricity costs in different operating conditions are based on the economic characteristics and the equipment load of a power plant. The paper describes the method for determination of electricity costs for condensing thermal power plants with permanent steam take-off for regeneration purposes and adjustable steam take-off for the needs of local heat energy consumers. The marginal costs for CHP plants are determined considering a number of different steam take-off from a turbine. At the electricity cost determination, auxiliary services also are taken into account. These can be reduced by adjusting the rotational speed of electric motors. The paper also shows how to determine the electricity costs for gas turbines, combined cycle gas turbines, and nuclear power plants. The position of hydro power plants among other PPs in the free market is also analysed. (authors)

  13. Cost reduction through system integration

    1994-01-01

    In resent years cost reduction has been a key issue in the petroleum industry. Several findings are not economically attractive at the current cost level, and for this and other reasons some of the major oil companies require the suppliers to have implemented a cost reduction programme to prequalify for projects. The present paper addresses cost reduction through system design and integration in both product development and working methods. This is to be obtained by the combination of contracts by reducing unnecessary coordination and allow re-use of proven interface designs, improve subsystem integration by ''top down'' system design, and improve communication and exchange of experience. 3 figs

  14. Approaches to estimating decommissioning costs

    Smith, R.I.

    1990-07-01

    The chronological development of methodology for estimating the cost of nuclear reactor power station decommissioning is traced from the mid-1970s through 1990. Three techniques for developing decommissioning cost estimates are described. The two viable techniques are compared by examining estimates developed for the same nuclear power station using both methods. The comparison shows that the differences between the estimates are due largely to differing assumptions regarding the size of the utility and operating contractor overhead staffs. It is concluded that the two methods provide bounding estimates on a range of manageable costs, and provide reasonable bases for the utility rate adjustments necessary to pay for future decommissioning costs. 6 refs

    Gurnea, Taylor P; Frye, Wesley P; Althausen, Peter L

    2016-12-01

    In the current health care environment, cost containment is more important than ever. Most physicians currently are unaware of the cost of operating room supplies. A large amount of waste occurs secondary to lack of knowledge and absence of physician incentives for cost saving. Many of the decisions for supply use can be based on good scientific evidence, which supports specific cost saving measures. Careful attention to blood utilization and use of tranexamic acid has the potential to save millions in the hip fracture treatment and arthroplasty treatments. Standardization of surgical preparation and draping can decrease costs and prevent costly surgical site infections. Following protocols and guidelines for bone graft and orthobiologics is critical. The clinical and legal repercussions of retained instruments and costs associated with dropped implants is a huge source of wasted health care dollars. Reprocessing programs for external fixators and tourniquets have been extremely successful. A myriad of opportunities for intraoperative cost savings exist that could be applied to nearly every orthopaedic surgery performed in the United States. It is incumbent on all surgeons to put aside the choices made out of habit and take part in reducing operating room waste for the benefit of hospitals, patients, and the health care system. When applied to the 5.3 million orthopaedic surgeries performed annually in the United States, billions of dollars could easily be saved with no adverse effect on patient care.

    2012-05-01

    Despite its prevalence and deleterious impact on patients and families, fecal incontinence remains an understudied condition. Few data are available on its economic burden in the United States. The aim of this study was to quantify per patient annual economic costs associated with fecal incontinence. A mail survey of patients with fecal incontinence was conducted in 2010 to collect information on their sociodemographic characteristics, fecal incontinence symptoms, and utilization of medical and nonmedical resources for fecal incontinence. The analysis was conducted from a societal perspective and included both direct and indirect (ie, productivity loss) costs. Unit costs were determined based on standard Medicare reimbursement rates, national average wholesale prices of medications, and estimates from other relevant sources. All cost estimates were reported in 2010 US dollars. This study was conducted at a single tertiary care institution. The analysis included 332 adult patients who had fecal incontinence for more than a year with at least monthly leakage of solid, liquid, or mucous stool. The primary outcome measured was the per patient annual economic costs associated with fecal incontinence. The average annual total cost for fecal incontinence was $4110 per person (median = $1594; interquartile range, $517-$5164). Of these costs, direct medical and nonmedical costs averaged $2353 (median, $1176; interquartile range, $294-$2438) and $209 (median, $75; interquartile range, $17-$262), whereas the indirect cost associated with productivity loss averaged $1549 per patient annually (median, $0; interquartile range, $0-$813). Multivariate regression analyses suggested that greater fecal incontinence symptom severity was significantly associated with higher annual direct costs. This study was based on patient self-reported data, and the sample was derived from a single institution. Fecal incontinence is associated with substantial economic cost, calling for more

  2. Uncovering your hidden occupancy costs.

    Apgar, M

    1993-01-01

    Senior managers at large companies may not believe that they can have much impact on the "bricks and mortar" of their cost structure. They may even think that occupancy costs are too insignificant to worry about, too technical to analyze, and too fixed to control. But as real estate consultant Mahlon Apgar argues, occupancy costs can hurt a company's earnings, share value, and overall performance. On the other hand, every dollar saved drops straight to the bottom line. Shearson Lehman Brothers, for example, has found that it can save as much as $20 million annually by reducing occupancy costs in its branch offices and headquarters. Managing occupancy costs isn't easy. But it is timely. As companies strive to improve productivity by consolidating functions and downsizing staff, they are saddled with excess office space. Expansions abroad present completely different market conditions that put a premium on reducing occupancy costs. At the same time, the changing nature of work is challenging deeply held beliefs about the workplace, and, consequently, traditional expectations of office space are giving way to innovations that are less costly and more productive. To manage occupancy costs, managers must be able to identify their components, measure their impact, understand what drives them, and develop options to change them. Four basic tools help diagnose problems: a cost history, a loss analysis, a component analysis, and a lease aging profile. Understanding cost drivers like leasing, location, and layout can give executives the insights they need to reduce occupancy costs while improving the effectiveness of facilities to support day-to-day operations.

  6. The Opportunity Cost of Capital

    Directory of Open Access Journals (Sweden)

    Ayman Chit PhD

    2015-04-01

    Full Text Available The opportunity cost of the capital invested in pharmaceutical research and development (R&D to bring a new drug to market makes up as much as half the total cost. However, the literature on the cost of pharmaceutical R&D is mixed on how, exactly, one should calculate this “hidden” cost. Some authors attempt to adopt models from the field of finance, whereas other prominent authors dismiss this practice as biased, arguing that it artificially inflates the R&D cost to justify higher prices for pharmaceuticals. In this article, we examine the arguments made by both sides of the debate and then explain the cost of capital concept and describe in detail how this value is calculated. Given the significant contribution of the cost of capital to the overall cost of new drug R&D, a clear understanding of the concept is critical for policy makers, investors, and those involved directly in the R&D.

    This study investigates the cost of chronic constipation care. A consecutive sample of 31 chronically constipated elderly patients. A not-for-profit long-term care facility in New Hyde Park, New York. Patient demographics and functional status, including activity of daily living scores, diagnosis, and medications were recorded. All constipation medication costs were obtained using the average wholesale price obtained from the Redbook (November 1999). All subjects were closely monitored for constipation care during two shifts a day (from 7:00 AM to 11:00 PM), over a 6-week period resulting in the collection of 1,860 shift reports. Each component of constipation treatment cost, namely drugs and staff time for drug administration, was identified and analyzed. The average number of nursing interactions for constipation treatment was 23.3 per month. The average cost per day for care specifically for the treatment of constipation was 2.11 US dollars. Fleet Enema trade mark and milk of magnesia accounted for 49% of all treatments. Administration (staffing) costs accounted for 70% of total drug costs. Although laxatives are the most frequently prescribed drugs used in long-term care settings, drug utilization patterns and associated costs in the treatment of chronic constipation have not been systematically reported. Our study identified staffing as the major cost factor in constipation care.

    The costs of care in the Netherlands have risen sharply since 2000 and will become increasingly difficult to finance in the future. How are those increasing costs to be paid, and who is to pay them? The Dutch care system is based on the principle of solidarity, which begs the question of who is

    The available literature on the cost of radiotherapy yields a large variation in data related to the specifics of the methodology used (the viewpoint of the analysis, time frame, health care system, etc.) and to the cost components and radiotherapy activities included. To overcome this difficulty, the reimbursement paid by medical insurance is commonly used as a proxy for the actual radiotherapy costs. Costs, however, generally bear little or no resemblance to charges, as the latter also include allowances for non-capacity use and profit margins. Accurate resource cost data are therefore more valid and should ideally be used in the context of economic evaluations and public health provisions. In addition to the theoretical problems related to obtaining accurate costs, it is difficult to interpret cost data across country borders because of differences in economics. If this is already the case for high income countries, using these cost data for low and middle income countries (LMICs) is even more problematic. Thus, there clearly is a need for calculations performed from the viewpoint of LMICs to prevent misapprehensions based on conclusions derived from data from their high income counterparts. The IAEA endeavours to assist Member States in accumulating appropriate and sufficient cost data for the initiation or expansion of radiation oncology services. Although relatively simple and easy to understand, the IAEA has found that in many countries where it has been involved in the establishment of new radiotherapy departments, the basic principles of cost calculation for radiotherapy facilities were not followed by the local planners. Radiotherapy needs careful planning, organization and a strong quality assurance (QA) programme in order to deliver safe treatments, due to the complexity of the planning and treatment process and the possibility of systematic errors. Administrators should be aware that the cost of building a radiotherapy facility and buying machines

  14. Cost estimating for CERCLA remedial alternatives a unit cost methodology

    1995-06-01

    The United States Environmental Protection Agency (EPA) Guidance for Conducting Remedial Investigations and Feasibility Studies Under CERCLA, Interim Final, dated October 1988 (EPA 1988) requires a detailed analysis be conducted of the most promising remedial alternatives against several evaluation criteria, including cost. To complete the detailed analysis, order-of-magnitude cost estimates (having an accuracy of +50 percent to -30 percent) must be developed for each remedial alternative. This paper presents a methodology for developing cost estimates of remedial alternatives comprised of various technology and process options with a wide range of estimated contaminated media quantities. In addition, the cost estimating methodology provides flexibility for incorporating revisions to remedial alternatives and achieves the desired range of accuracy. It is important to note that the cost estimating methodology presented here was developed as a concurrent path to the development of contaminated media quantity estimates. This methodology can be initiated before contaminated media quantities are estimated. As a result, this methodology is useful in developing cost estimates for use in screening and evaluating remedial technologies and process options. However, remedial alternative cost estimates cannot be prepared without the contaminated media quantity estimates. In the conduct of the feasibility study for Operable Unit 5 at the Fernald Environmental Management Project (FEMP), fourteen remedial alternatives were retained for detailed analysis. Each remedial alternative was composed of combinations of remedial technologies and processes which were earlier determined to be best suited for addressing the media-specific contaminants found at the FEMP site, and achieving desired remedial action objectives

  15. Sequential Construction of Costly Networks

    Energy Technology Data Exchange (ETDEWEB)

    Gutfraind, Alexander [Los Alamos National Laboratory

    2011-01-01

    Natural disasters or attacks often disrupt infrastructure networks requiring a costly recovery. This motivates an optimization problem where the objecitve is to construct the nodes of a graph G(V;E), and the cost of each node is dependent on the number of its neighbors previously constructed, or more generally, any properties of the previously-completed subgraph. In this optimization problem the objective is to find a permutation of the nodes which results in the least construction cost. We prove that in the case where the cost of nodes is a convex function in the number of neighbors, the optimal construction sequence is to start at a single node and move outwards. We also introduce algorithms and heuristics for solving various instances of the problem. Those methods can be applied to help reduce the cost of recovering from disasters as well as to plan the deployment of new network infrastructure.

    Though the context may vary, the topic of the day in the oil and gas industry is ''finding costs per barrel.'' First, there have been numerous articles in both the popular media and the industry press that have argued it is cheaper for companies to buy reserves that find them with the drill bit. Financial analysts have emphasized the importance of comparing relative finding costs when evaluating different companies. The success of failure of a company's management has been judged on the basis of finding costs. In discussing oil and gas prices, economists commonly refer to the relationship between the market prices of oil and gas and their finding costs, and no discussion of the U.S. petroleum industry and the development of a national energy policy is complete without reference to finding costs.

  17. Calculating utility prudency issue costs

    1985-01-01

    The nuclear industry, particularly utilities and their construction, engineering and vendor agents, is faced with a surging increase in prudency management audits. What started as primarily a nuclear project-oriented requirement has spread to encompass most significant utility capital construction projects. Such audits are often a precedent condition to commencement of rate hearings. The cost engineer, a primary major capital construction project participant, is required to develop or critique ''prudency issue'' costs as part of such audits. Although utility costs in the broadest sense are potentially at issue, this paper concentrates on the typical project/construction management costs. The costs of design, procurement and construction are all subject to the calculation process

    1992-01-01

    Costing of transmission services of electrical utilities is required for transactions involving the transport of energy over a power network. The calculation of these costs based on Short Run Marginal Costing (SRMC) is preferred over other methods proposed in the literature due to its economic efficiency. In the research work discussed here, the concept of probabilistic costing of use-of-system based on SRMC which emerges as a consequence of the uncertainties in a power system is introduced using two different approaches. The first approach, based on the Monte Carlo method, generates a large number of possible system states by simulating random variables in the system using pseudo random number generators. A second approach to probabilistic use-of-system costing is proposed based on numerical convolution and multi-area representation of the transmission network. (UK)

  19. Agency costs and income taxation

    Full Text Available This paper analyzes agency costs and the moral hazard problem in the presence of income taxation. As basic framework, income taxes are integrated in the hidden action model of agency theory. In the case of symmetric information no agency costs occur, i.e. optimal risk-sharing can be achieved, if and only if the tax is proportional. It is well-known that asymmetric information causes a welfare loss, termed agency costs, even if no taxes are imposed. Introducing a proportional income tax now increases (decreases these agency costs if the agent exhibits decreasing (increasing absolute risk aversion. Additionally, we show that non-proportional taxes cause higher (lower agency costs than a proportional tax if the agent’s marginal tax rate exceeds (is smaller than the marginal tax rate of the principal.

  20. The Psychology of Cost Estimating

    Cost estimation for large (and even not so large) government programs is a challenge. The number and magnitude of cost overruns associated with large Department of Defense (DoD) and National Aeronautics and Space Administration (NASA) programs highlight the difficulties in developing and promulgating accurate cost estimates. These overruns can be the result of inadequate technology readiness or requirements definition, the whims of politicians or government bureaucrats, or even as failures of the cost estimating profession itself. However, there may be another reason for cost overruns that is right in front of us, but only recently have we begun to grasp it: the fact that cost estimators and their customers are human. The last 70+ years of research into human psychology and behavioral economics have yielded amazing findings into how we humans process and use information to make judgments and decisions. What these scientists have uncovered is surprising: humans are often irrational and illogical beings, making decisions based on factors such as emotion and perception, rather than facts and data. These built-in biases to our thinking directly affect how we develop our cost estimates and how those cost estimates are used. We cost estimators can use this knowledge of biases to improve our cost estimates and also to improve how we communicate and work with our customers. By understanding how our customers think, and more importantly, why they think the way they do, we can have more productive relationships and greater influence. By using psychology to our advantage, we can more effectively help the decision maker and our organizations make fact-based decisions.

    This report is concerned with the escalation of capital costs of nuclear central station power plants between the early 1960s and the present. The report presents an historical overview of the development of the nuclear power industry and cost escalation in the industry, using existing data on orders and capital costs. New data are presented on regulatory delays in the licensing process, derived from a concurrent study being carried on in the Social Science group at Caltech. The conclusions of the study are that nuclear capital costs have escalated more rapidly than the GNP deflator or the construction industry price index. Prior to 1970, cost increases are related to bottleneck problems in the nuclear construction and supplying industries and the regulatory process; intervenors play only a minor role in cost escalation. After 1970, generic changes introduced into the licensing process by intervenors (including environmental impact reviews, antitrust reviews, more stringent safety standards) dominate the cost escalation picture, with bottlenecks of secondary importance. Recent increases in the time from application for a construction permit to commercial operation are related not only to intervenor actions, but also to suspensions, cancellations or postponements of construction by utilities due to unfavorable demand or financing conditions

    Cost is a key issue in the spreading of any technology. In this work, the cost of hydrogen is analyzed and determined, for hydrogen obtained by electrolysis. Different contributing partial costs are taken into account to calculate the hydrogen final cost, such as energy and electrolyzers taxes. Energy cost data is taken from official URLs, while electrolyzer costs are obtained from commercial companies. The analysis is accomplished under different hypothesis, and for different countries: Germany, France, Austria, Switzerland, Spain and the Canadian region of Ontario. Finally, the obtained costs are compared to those of the most used fossil fuels, both in the automotive industry (gasoline and diesel) and in the residential sector (butane, coal, town gas and wood), and the possibilities of hydrogen competing against fuels are discussed. According to this work, in the automotive industry, even neglecting subsidies, hydrogen can compete with fossil fuels. Hydrogen can also compete with gaseous domestic fuels. Electrolyzer prices were found to have the highest influence on hydrogen prices. (orig.)

    This thesis concerns cost allocation problems in distribution planning. The cost allocation problems we study are illustrated using the distribution planning situation at the Logistics department of Norsk Hydro Olje AB. The planning situation is modeled as a Traveling Salesman Problem and a Vehicle Routing Problem with an inhomogeneous fleet. The cost allocation problems are the problems of how to divide the transportation costs among the customers served in each problem. The cost allocation problems are formulated as cooperative games, in characteristic function form, where the customers are defined to be the players. The games contain five and 21 players respectively. Game theoretical solution concepts such as the core, the nucleolus, the Shapley value and the {tau}-value are discussed. From the empirical results we can, among other things, conclude that the core of the Traveling Salesman Game is large, and that the core of the Vehicle Routing Game is empty. In the accounting of Norsk Hydro the cost per m{sup 3} can be found for each tour. We conclude that for a certain definition of the characteristic function, a cost allocation according to this principle will not be included in the core of the Traveling Salesman Game. The models and methods presented in this thesis can be applied to transportation problems similar to that of Norsk Hydro, independent of the type of products that are delivered. 96 refs, 11 figs, 26 tabs

    A cost of illness study was undertaken on behalf of the French Ministry of Health to estimate the annual cost of stroke in France with the goal of better understanding the current economic burden so that improved strategies for care may be developed. Using primary data from exhaustive national databases and both top-down and bottom-up approaches, the stroke-related costs for healthcare, nursing care and lost productivity were estimated. The total healthcare cost of stroke patients in France in 2007 was €5.3 billion, 92% of which was borne by statutory health insurance. The average cost of incident cases was €16 686 per patient in the first year, while the annual cost of prevalent cases was a little less than half that amount (€8099). Nursing care costs were estimated at €2.4 billion. Lost productivity reached €255.9 million and that income loss for stroke patients was partially compensated by €63.3 million in social benefit payments. With healthcare costs representing 3% of total health expenditure in France, stroke constitutes an ongoing burden for the health system and overall economy. Nursing care added nearly half again the amount spent on healthcare, while productivity losses were more limited because nearly 80% of acute incident strokes were in patients over age 65. The high cost of illness underscores the need for improved prevention and interventions to limit the disabling effects of stroke. © 2013 The Author(s) European Journal of Neurology © 2013 EFNS.

    Despite the fact that completion of construction projects has a direct positive impact on the growth of national and local economies as well as humans' wellbeing, construction projects, especially in the urban areas, generate serious environmental nuisances for the adjacent residents and have unintentional adverse impacts on their surrounding environment. Construction causative adverse impacts on the neighbouring communities are known as the social costs. This study aims to present a state-of-the-art overview of social costs in construction industry in terms of definition, consideration, classification and quantification. Furthermore, it is aimed to bring the construction social cost phenomenon for the agenda of Environmental Impact Assessors.

    Gas prices only seem high. When you say fillerup, you pay but a fraction of the actual cost. Not included are the tens of billions (close to $50 for each barrel of oil) the military spends annually to protect oil fields in the Persian Gulf. Then tack on the hidden costs of environmental degradation, health effects, lost employment, government subsidies and more. Sooner or later, the public pays the entire price. Bringing market prices in line with energy's hidden burdens will be one of the great challenges of the coming decades. The author describes these hidden costs and makes estimates of them

    At a recent symposium, the economic costs of nuclear power were examined in four lectures which considered; (1) The performance of different types, size and ages of nuclear power plants. (2) The comparison between coal and nuclear power costs based on the principle of net effective cash. (3) The capital requirements of a nuclear programme. (4) The comparative costs, now and in the future, of coal-fired and nuclear plants. It is concluded that uncertainties seem to get greater rather than smaller with time probably due to the high and fluctuating world inflation rates and the great uncertainty about world economic performance introduced by the politicising of world oil supplies.

    Cook, A.; Lockett, L.E.

    1978-01-01

    In order to optimise capital expenditure on measures to protect workers against radiation it would be useful to have a means to measure radiation dose in money terms. Because labour has to be employed to perform radiation work there must be some relationship between the wages paid and the doses received. Where the next increment of radiation dose requires additional labour to be recruited the cost will at least equal the cost of the extra labour employed. This paper examines some of the factors which affect the variability of the labour cost of radiation dose and notes that for 'in-plant' exposures the current cost per rem appears to be significantly higher than values quoted in ICRP Publication 22. An example is given showing how this concept may be used to determine the capital it is worth spending on installed plant to prevent regular increments of radiation dose to workers. (author)

    This report addresses the question of estimating the capital and operating costs for LIS (Laser Isotope Separation) lasers, which have performance requirements well beyond the state of mature art. This question is seen with different perspectives by political leaders, ERDA administrators, scientists, and engineers concerned with reducing LIS to economically successful commercial practice, on a timely basis. Accordingly, this report attempts to provide ''ballpark'' estimators for capital and operating costs and useful design and operating information for lasers based on mature technology, and their LIS analogs. It is written very basically and is intended to respond about equally to the perspectives of administrators, scientists, and engineers. Its major contributions are establishing the current, mature, industrialized laser track record (including capital and operating cost estimators, reliability, types of application, etc.) and, especially, evolution of generalized estimating procedures for capital and operating cost estimators for new laser design

    This study systematically compares the external costs and benefits of different electricity generating technologies. It covers environmental and employment effects, the depletion of natural resources, and public subsidies. Electricity production based on fossil fuels and nuclear energy compared with electricity production based on wind energy and photovoltaic systems. The study shows that wind and photovoltaic solar energy induce far less social costs than conventionally generated electricity. The impact of excluding social costs on the competitive position of the different energy technologies is analyzed. It is shown that the allocation process is seriously distorted resulting in sub-optimal investment decisions concerning competing energy technologies. This exclusion of social costs can delay the introduction of renewable energy sources by more than ten years and results in considerable losses to society. (orig./HSCH) With 17 figs., 24 tabs

    Full Text Available Aurel O Iuga,1,2 Maura J McGuire3,4 1Johns Hopkins Bloomberg School of Public Health, 2Johns Hopkins University, 3Johns Hopkins Community Physicians, 4Johns Hopkins University School of Medicine, Baltimore, MD, USA Abstract: Medication nonadherence is an important public health consideration, affecting health outcomes and overall health care costs. This review considers the most recent developments in adherence research with a focus on the impact of medication adherence on health care costs in the US health system. We describe the magnitude of the nonadherence problem and related costs, with an extensive discussion of the mechanisms underlying the impact of nonadherence on costs. Specifically, we summarize the impact of nonadherence on health care costs in several chronic diseases, such as diabetes and asthma. A brief analysis of existing research study designs, along with suggestions for future research focus, is provided. Finally, given the ongoing changes in the US health care system, we also address some of the most relevant and current trends in health care, including pharmacist-led medication therapy management and electronic (e-prescribing.

  8. Chapter 17. Engineering cost analysis

    Energy Technology Data Exchange (ETDEWEB)

    Higbee, Charles V.

    1998-01-01

    In the early 1970s, life cycle costing (LCC) was adopted by the federal government. LCC is a method of evaluating all the costs associated with acquisition, construction and operation of a project. LCC was designed to minimize costs of major projects, not only in consideration of acquisition and construction, but especially to emphasize the reduction of operation and maintenance costs during the project life. Authors of engineering economics texts have been very reluctant and painfully slow to explain and deal with LCC. Many authors devote less than one page to the subject. The reason for this is that LCC has several major drawbacks. The first of these is that costs over the life of the project must be estimated based on some forecast, and forecasts have proven to be highly variable and frequently inaccurate. The second problem with LCC is that some life span must be selected over which to evaluate the project, and many projects, especially renewable energy projects, are expected to have an unlimited life (they are expected to live for ever). The longer the life cycle, the more inaccurate annual costs become because of the inability to forecast accurately.

    In March 1988, The Office of Governmental and Public Affairs (GPA) completed a report (NUREG-1311) entitled, ''Funding the NRC Training Program for States.'' This report responded to a Commission's request for study of NRC's long-standing practice of paying the travel and per diem of state personnel who attend NRC sponsored training. In May 1988, the Chairman endorsed the report in most respects but asked for further study of a cost sharing of travel and per diem costs. As a result, the Director of GPA's State, Local and Indian Tribe Programs (SLITP) established a Task Force comprised of representatives from the Conference of Radiation Control Program Directors, Inc., the Agreement States and the NRC to look at ways that the states can share the costs of NRC training, particularly travel and per diem. At the request of the Director, GPA, the Task Force also looked at related cost and quantity issues associated with the NRC training program for state personnel. This report includes a discussion of NRC and state perspectives on the issue of sharing travel and per diem costs, a discussion of options, and recommendations for likely cost savings and quality of training improvement. 1 ref., 3 figs., 2 tabs

  10. Cost analysis of flexible ureterorenoscopy.

    Science.gov (United States)

    Collins, J W; Keeley, F X; Timoney, A

    2004-05-01

    To assess the costs of flexible ureterorenoscopy. Data were collected prospectively for 100 cases using a new flexible ureteroscope (DUR8, Circon ACMI, Stamford, USA), including the indications for flexible ureterorenoscopy, use of laser probes, disposable instrumentation, and the cost and timing of ureteroscope repair. Of the 100 procedures 68 were for stone disease, 21 for known or suspected transitional cell carcinoma (TCC), six were diagnostic only and five were for pelvi-ureteric junction obstruction. The ureteroscope was repaired after the 29th and 88th cases. The ability of the ureteroscope to deflect was maintained throughout. At the time of purchase the ureteroscope was listed at pound 15 000 and each repair/exchange currently costs pound 4200, thus the total expenditure on the ureteroscope was pound 23 400. Total expenditure on ancillary equipment was pound 28 727, of which pound 22 927 was on disposables and pound 5800 on 10 laser probes. In this series the costs of the ancillary equipment exceeded the purchase and maintenance of the ureteroscope, and we expect this trend to continue in the long term. The advent of more durable ureteroscopes may ultimately reduce the frequency of costly repairs. The cost of disposables should be considered in planning the budget.

  11. Nuclear plant life cycle costs

    International Nuclear Information System (INIS)

    Durante, R.W.

    1994-01-01

    Life cycle costs of nuclear power plants in the United States are discussed. The author argues that these costs have been mishandled or neglected. Decommissioning costs have escalated, e.g. from $328 per unit in 1991 to $370 in 1993 for the Sacramento Municipal Utility District, though they still only amount to less than 0.1 cent per kWh. Waste management has been complicated in the U.S. by the decision to abandon civilian reprocessing; by the year 2000, roughly 30 U.S. nuclear power units will have filled their storage pools; dry storage has been delayed, and will be an expense not originally envisaged. Some examples of costs of major component replacement are provided. No single component has caused as much operational disruption and financial penalties as the steam generator. Operation and maintenance costs have increased steadily, and now amount to more than 70% of production costs. A strategic plan by the Nuclear Power Oversight Committee (of U.S. utilities) will ensure that the ability to correctly operate and maintain a nuclear power plant is built into the original design. 6 figs

    Full Text Available Management decision must be based on relevant costs (costs that allow for the best measures for business management, recognized by their forecasting characteristics which records hidden or opportunity costs, social costs and outsourced costs. Correctly predicted a profit is to build costs for possible revenue. The cost is a sacrifice, resource consumption. Because decisions aimed at future activities, the management calls in this respect, detailed information on future costs, some of which are not included in accounting data collection system. The power of decision maker on costs is therefore limited.d

    Bosker, E.M.; Garretsen, J.H.

    Trade costs are a crucial element of New Economic Geography (NEG) models. Without trade costs there is no role for geography. In empirical NEG studies the unavailability of direct trade cost data calls for the need to approximate these trade costs by introducing a trade cost function. In doing so,

  15. Low cost solar air heater

    International Nuclear Information System (INIS)

    Gill, R.S.; Singh, Sukhmeet; Singh, Parm Pal

    2012-01-01

    Highlights: ► Single glazed low cost solar air heater is more efficient during summer while double glazed is better in winter. ► For the same initial investment, low cost solar air heaters collect more energy than packed bed solar air heater. ► During off season low cost solar air heater can be stored inside as it is light in weight. - Abstract: Two low cost solar air heaters viz. single glazed and double glazed were designed, fabricated and tested. Thermocole, ultraviolet stabilised plastic sheet, etc. were used for fabrication to reduce the fabrication cost. These were tested simultaneously at no load and with load both in summer and winter seasons along with packed bed solar air heater using iron chips for absorption of radiation. The initial costs of single glazed and double glazed are 22.8% and 26.8% of the initial cost of packed bed solar air heater of the same aperture area. It was found that on a given day at no load, the maximum stagnation temperatures of single glazed and double glazed solar air heater were 43.5 °C and 62.5 °C respectively. The efficiencies of single glazed, double glazed and packed bed solar air heaters corresponding to flow rate of 0.02 m 3 /s-m 2 were 30.29%, 45.05% and 71.68% respectively in winter season. The collector efficiency factor, heat removal factor based on air outlet temperature and air inlet temperature for three solar air heaters were also determined.

  16. Costing methods for nuclear desalination

    International Nuclear Information System (INIS)

    1966-01-01

    The question of the methods used for costing desalination plants has been recognized as very important in the economic choice of a plant and its optimization. The fifth meeting of the Panel on the Use of Nuclear Energy in Saline Water Conversion, convened by the International Atomic Energy Agency in April 1965, noted this fact and recommended the preparation of a report on suitable methods for costing and evaluating nuclear desalination schemes. The Agency has therefore prepared this document, which was reviewed by an international panel of experts that met in Vienna from 18 to 22 April, 1966. The report contains a review of the underlying principles for costing desalination plants and of the various methods that have been proposed for allocating costs in dual-purpose plants. The effect of the different allocation methods on the water and power costs is shown at the end of the report. No attempt is made to recommend any particular method, but the possible limitations of each are indicated. It is hoped that this report will help those involved in the various phases of desalination projects

  17. Costs of electronuclear fuel production

    International Nuclear Information System (INIS)

    Flaim, T.; Loose, V.

    1978-07-01

    The Los Alamos Scientific Laboratory (LASL) proposes to study the electronuclear fuel producer (EFP) as a means of producing fissile fuel to generate electricity. The main advantage of the EFP is that it may reduce the risks of nuclear proliferation by breeding 233 U from thorium, thereby avoiding plutonium separation. A report on the costs of electronuclear fuel production based upon two designs considered by LASL is presented. The findings indicate that the EFP design variations considered are not likely to result in electricity generation costs as low as the uranium fuel cycle used in the US today. At current estimates of annual fuel output (500 kg 233 U per EFP), the costs of electricity generation using fuel produced by the EFP are more than three times higher than generating costs using the traditional fuel cycle. Sensitivity analysis indicates that electronuclear fuel production would become cost competitive with the traditional uranium fuel cycle when U 3 O 8 (yellowcake) prices approach $1000 per pound

  18. Minimizing activated carbons production cost

    International Nuclear Information System (INIS)

    Stavropoulos, G.G.; Zabaniotou, A.A.

    2009-01-01

    A detailed economic evaluation of activated carbons production process from various raw materials is undertaken using the conventional economic indices (ROI, POT, and NPV). The fundamental factors that affect production cost were taken into account. It is concluded that for an attractive investment in activated carbons production one should select the raw material with the highest product yield, adopt a chemical activation production scheme and should base product price on product-surface area (or more generally on product adsorption capacity for the adsorbate in consideration). A raw material that well meets the above-mentioned criteria is petroleum coke but others are also promising (charcoals, and carbon black). Production cost then can be optimized by determining its minimum value of cost that results from the intercept between the curves of plant capacity and raw material cost - if any. Taking into account the complexity of such a techno-economic analysis, a useful suggestion could be to start the evaluations from a plant capacity corresponding to the break-even point, i. e. the capacity at which income equals production cost.

    2001-06-01

    Full Text Available Activity based costing is a method of identifying and tracking the operating costs directly associated with processing items. It is the practice of focusing on some unit of output, such as a purchase order or an assembled automobile and attempting to determine its total as precisely as poccible based on the fixed and variable costs of the inputs.You use ABC to identify, quantify and analyze the various cost drivers (such as labor, materials, administrative overhead, rework. and to determine which ones are candidates for reduction.A processes any activity that accepts inputs, adds value to these inputs for customers and produces outputs for these customers. The customer may be either internal or external to the organization. Every activity within an organization comprimes one or more processes. Inputs, controls and resources are all supplied to the process.A process owner is the person responsible for performing and or controlling the activity.The direction of cost through their contact to partial activity and processes is a new modern theme today. Beginning of this method is connected with very important changes in the firm processes.ABC method is a instrument , that bring a competitive advantages for the firm.

  8. Modifications to Replacement Costs System

    International Nuclear Information System (INIS)

    Godec, M.

    1989-01-01

    The purpose of this memorandum is to document the improvements and modifications made to the Replacement Costs of Crude Oil (REPCO) Supply Analysis System. While some of this work was performed under our previous support contract to DOE/ASFE, we are presenting all modifications and improvements are presented here for completeness. The memo primarily documents revisions made to the Lower-48 Onshore Model. Revisions and modifications made to other components and models in the REPCO system which are documented elsewhere are only highlighted in this memo. Generally, the modifications made to the Lower-48 Onshore Model reflect changes that have occurred in domestic drilling, oil field costs, and reserves since 1982, the date of the most recent available data used for the original Replacement Costs report, published in 1985

  9. Developing macroeconomic energy cost indicators

    International Nuclear Information System (INIS)

    Oberndorfer, Ulrich

    2012-01-01

    Indicators are more and more drawn on for policy making and assessment. This is also true for energy policy. However, while numerous different energy price figures are available, subordinate energy cost indicators are lacking. This paper lays out a general concept for such indicator sets and presents a flexible framework for representative and consistent energy cost indicators with an underlying weighting principle based on consumption shares. Their application would provide interesting new insights into the relationship between energy cost burdens of different sectors and countries. It would allow for more rigorous analysis in the field of energy economics and policy, particularly with regard to market monitoring and impact assessment as well as ex-post-policy analysis.

  10. The cost of nuclear power

    International Nuclear Information System (INIS)

    Guinness, J.R.S.; Myerscough, C.J.; Curran, D.; Wilcock, C.C.

    1990-01-01

    This paper starts with a memorandum sent in February 1990 from the Department of Energy to the government's select committee of energy about the cost of nuclear power in the United Kingdom (UK) and the reasons behind the government's decision to withdraw the UK's nuclear generating capacity from the electricity privatization scheme. The remainder of the paper refers to evidence from officials at the Department of Energy, to the select committee. They differ from Lord Marshall, latterly of the Central Electricity Generating Board, on the ''obligation to supply'' issue and the question of risks versus rewards. Officials were closely questioned as to why they had failed to monitor rising costs within the nuclear industry when it was still in the private sector and make that information available to Ministers, and as to how huge changes in the published costs of nuclear power had come about.

  11. Reduction of LNG FOB cost

    International Nuclear Information System (INIS)

    Aoki, Ichizo; Kikkawa, Yoshitsugi

    1997-01-01

    To achieve a competitive LNG price for the consumers against other energy sources, reduction of LNG FOB (Free on Board) cost i.e. LNG cost at LNG ship flange, will be the key item. It is necessary to perform a many optimization studies (or value engineering) for each stage of the LNG project. These stages are: Feasibility study; Conceptual design - FEED (Front End Engineering and Design); EPC (Engineering, Procurement and Construction); Operation and maintenance. Since the LNG plant forms one part of the LNG chain, starting from gas production to LNG receiving, and requires several billion US dollar of investment, the consequences of a plant shut down on the LNG chain are clear, it is, therefore, important to get high availability which will also contribute the reduction of LNG FOB cost.

  12. The Costs of Climate Change

    Guo, Jason

    2018-03-01

    This research paper talks about the economic costs of climate change, as well as the costs involved in responding to climate change with alternative fuels. This paper seeks to show that climate change, although seemingly costly in the short run, will both save future generations trillions of dollars and serve as a good economic opportunity. Scientists have long argued that the fate of humanity depends on a shift towards renewable energy. However, this paper will make clear that there is also an economic struggle. By embracing alternative fuels, we will not only lessen the danger and the frequency of these natural disasters but also strengthen the world’s financial state. Although a common argument against responding to climate change is that it is too expensive to make the switch, this research shows that in the future, it will save millions of lives and trillions of dollars. The only question left for policymakers is whether they will grasp this energy source shift.

    Healthcare leaders should address three important questions as they prepare to implement new costing systems: Do all providers in their organizations' systems, networks, or partnerships share the same definitions of unit of care and of fixed, variable, incremental, direct, and indirect costs? What are the maintenance processes and protocols for cost center and period matching of revenues and costs? If some providers within a network or partnership are not using costing systems, can an enterprise derive surrogate cost per unit of care?

  18. EPR project construction cost control

    International Nuclear Information System (INIS)

    Duflo, D.; Pouget-Abadie, X.; Dufour, A.; Kauffmann, G.

    2001-01-01

    The EPR project is now managed by EDF in cooperation with the German Utilities. The main engineering activities for this period are related to the preparation of construction project management, deepening of some safety issues, definition of the project technical reference. The EPR project concerns the so-called reference unit, that is an isolated first-off unit, with unit electrical power of about 1500 MW. The construction costs evaluated are those of the nuclear island, the conventional island, site facilities, installation work and the administrative buildings. The EPR project construction cost evaluation method applies to all the equipment installed and commissioned. It requires the availability of a preliminary project detailed enough to identify the bill of quantities. To these quantities are then assigned updated unit prices that are based either on cost bases for similar and recent facilities or taken from request for quotation for similar equipment or result from gains due to contractual conditions benefiting from simplifications in the functional and technical specifications. The input and output data are managed in a model that respects the breakdown on which the evaluation method is based. The structural organization of this method reflects a functional breakdown on the one hand (nuclear island, conventional island, common site elements) and on the other hand a breakdown according to equipment or activity (civil engineering, mechanics, electricity, instrumentation and control). This paper discusses the principle and the method of construction cost evaluation carried out, the cost data base and input and output parameters as well as results and oncoming cost analysis tasks.

    A reflection of the place cost analysis holds in membrane process technology research and development is provided. The review encompassed two membrane processes and applications: (a) reverse osmosis (RO) for seawater desalination, and (b) membrane bioreactor (MBR) technology for wastewater treatment. The cost analysis undertaken extended to (i) the determination of operating expenditure (OPEX) trends using simple analytical expressions, (ii) the subsequent estimation of the sensitivity of OPEX to individual system parameters, and (iii) published data on CAPEX for individual full-scale installations or from cost analyses. An appraisal of the peer-reviewed literature through a survey of a leading scientific database was also carried out. This bibliometric analysis was based on authors' keywords; it aimed to establish the profile of process cost for each of the two applications when compared with other popular research topics. The OPEX analysis, ostensibly through a consideration of specific energy demand in kWh per m 3 permeate, revealed it to relate primarily to hydrodynamics in the case of RO, and to both membrane fouling and air scouring for MBRs. The bibliometric analysis of research trends revealed a marked difference in emphasis on cost aspects between the two research areas, with the focus on cost specifically being 16 times greater for RO desalination of seawater than MBR treatment of wastewater. MBR research appears to be dominated by fouling and foulant characterisation, making up almost a quarter of all studies, notwithstanding evidence from practitioners that other process parameters are as important in determining MBR process OPEX and operability.

  20. The cost of nuclear accidents

    International Nuclear Information System (INIS)

    2015-01-01

    Proposed by a technical section of the SFEN, and based on a meeting with representatives of different organisations (OECD-NEA, IRSN, EDF, and European Nuclear Energy Forum), this publication addresses the economic consequences of a severe accident (level 6 or 7) within an electricity producing nuclear power plant. Such an assessment essentially relies on three pillars: release of radio-elements outside the reactor, the scenario of induced consequences, and the method of economic quantification. After a recall and a comment of safety arrangements, and of the generally admitted probability of such an accident, this document notices that several actors are concerned by nuclear energy and are trying to assess accident costs. The issue of how to assess a cost (or costs) of a nuclear accident is discussed: there are in fact several types of costs and consequences. Thus, some costs can be rather precisely quantified when some others can be difficult to assess or with uncertainty. The relevance of some cost categories appears to be a matter of discussion and one must not forget that consequences can occur on a long term. The need for methodological advances is outlined and three categories of technical objectives are identified for the assessment (efficiency of safety measures to be put forward to mitigate the risk via a better accident management, compensation of victims and nuclear civil responsibility, and comparison of electricity production sectors and assessment of externalisation to guide public choices). It is outlined that the impact of accidents depend on several factors, that the most efficient mean to limit consequences of accidents is of course to limit radioactive emissions

    Full Text Available In order to determine the variability of pequi tree (Caryocar brasiliense Camb. populations, volatile compounds from fruits of eighteen trees representing five populations were extracted by headspace solid-phase microextraction and analyzed by gas chromatography-mass spectrometry. Seventy-seven compounds were identified, including esters, hydrocarbons, terpenoids, ketones, lactones, and alcohols. Several compounds had not been previously reported in the pequi fruit. The amount of total volatile compounds and the individual compound contents varied between plants. The volatile profile enabled the differentiation of all of the eighteen plants, indicating that there is a characteristic profile in terms of their origin. The use of Principal Component Analysis and Cluster Analysis enabled the establishment of markers (dendrolasin, ethyl octanoate, ethyl 2-octenoate and β-cis-ocimene that discriminated among the pequi trees. According to the Cluster Analysis, the plants were classified into three main clusters, and four other plants showed a tendency to isolation. The results from multivariate analysis did not always group plants from the same population together, indicating that there is greater variability within the populations than between pequi tree populations.A fim de determinar a variabilidade de populações de pequizeiro (Caryocar brasiliense Camb., compostos voláteis de frutos de dezoito árvores representando cinco populações foram extraídos por microextração em fase sólida no modo headspace e analisados por cromatografia a gás acoplada à espectrometria de massas.

    The cost effectiveness of the Magnox reactors is challenged. Tabulated data show that both Magnox and AGR reactors are nearly 10% more expensive to run than coal-fired stations. The costs are considered in some detail. The situation for AGRs in general is considered first, then for the Torness reactor in Scotland. The economic arguments presented on behalf of PWR type reactors are also questioned as well as the more fundamental questions of whether the electricity demand justifies more nuclear power plants being built. The economics of nuclear power in the USA and France is also considered. (UK)

    Pathological gambling creates enormous problems for the afflicted individuals, their families, employers, and society, and has numerous disastrous financial consequences. The present study evaluates the financial burdens of pathological gambling by questioning pathological gamblers in treatment in Gamblers Anonymous (n=60; 56 males, 4 females; mean age = 40 years old) about personal debts, loss of productivity at work, illegal activities, medical costs and the presence of other dependencies. Results show that important debts, loss of productivity at work and legal problems are associated with pathological gambling. Discussion is formulated in terms of the social cost of adopting a liberal attitude toward the legalization of various gambling activities.

    A comparative study of costs per bed per day in teaching hospitals affiliated with Monash University compared with large non-teaching metropolitan hospitals (1964 to 1974) shows they are much higher in teaching hospitals. There is no evidence that this is due to the additional costs arising from the clinical schools. Research in the teaching hospitals and the accompanying high professional standards and demands on services are major factors accounting for the difference. Over the decade studied, the resident staff have increased by 77% and other salaried staff by 24%. The index of expenditure for the three teaching hospitals in the decade has increased by 386%.

    1 - Description of program or function: The Cost Estimating Computer Program CECP, designed for use on an IBM personal computer or equivalent, was developed for estimating the cost of decommissioning boiling water reactor (BWR) and light-water reactor (PWR) power stations to the point of license termination. 2 - Method of solution: Cost estimates include component, piping, and equipment removal costs; packaging costs; decontamination costs; transportation costs; burial volume and costs; and manpower staffing costs. Using equipment and consumables costs and inventory data supplied by the user, CECP calculates unit cost factors and then combines these factors with transportation and burial cost algorithms to produce a complete report of decommissioning costs. In addition to costs, CECP also calculates person-hours, crew-hours, and exposure person-hours associated with decommissioning. 3 - Restrictions on the complexity of the problem: The program is designed for a specific waste charge structure. The waste cost data structure cannot handle intermediate waste handlers or changes in the charge rate structures. The decommissioning of a reactor can be divided into 5 periods. 200 different items for special equipment costs are possible. The maximum amount for each special equipment item is 99,999,999$. You can support data for 10 buildings, 100 components each; ESTS1071/01: There are 65 components for 28 systems available to specify the contaminated systems costs (BWR). ESTS1071/02: There are 75 components for 25 systems available to specify the contaminated systems costs (PWR)

    Volicer, B J; Romagnoli, D M

    1988-12-01

    The purpose of the project was to develop a model for predicting costs for potential new HMO subscribers, using available cost data from fiscal year 1985 for current enrollees of a large HMO. Regression analysis of aggregated clinic, referral, and hospital cost data using a log transformation of cost indicated that 20 percent of the variation in cost could be explained by sex and coverage type of the subscriber, compared with 7 percent explainable by a simple comparison of costs for single versus family subscribers. Subscriber age, while by itself a significant and nonlinear predictor of cost, was not significant when controlled for coverage type. Application of the model to 28 large companies yielded predicted costs well correlated with observed costs (r = .75, p less than .01). Prediction was significantly better for companies with low observed mean costs than for companies with high observed mean costs.

    1994-08-01

    For many years, the evolution of Argentina's healthcare system has been influenced by political and economic instability. Inflation and hyperinflation have led to anarchic development of both health administration systems and hospitals. Critical care grew in a similar manner, resulting in a mix of > 500 critical care units with very different levels of technology and trained personnel. Cost-containment policies have been implemented mainly by health administration systems. Public institutions (university and large provincial and county hospitals) have suffered hard budget cuts that have resulted in a decrease in the quality of care and the loss of trained human resources. Union organizations, which cover the healthcare costs of > 60% of the population, implemented a low reimbursement policy that resulted in low standards of care for critically ill patients. The country's private hospital system is extremely heterogenous, ranging from little, simple institutions with a 20- to 30-bed capacity to great private institutions with international standards of care. Cost-containment efforts have been sporadic and isolated, and statistical data to analyze the results are lacking. In order to formulate a strategy of cost-containment in the near future, accreditation and categorization of critical care units and human resources training are being implemented by health authorities and the Argentine Society of Critical Care Medicine.

This solution allows decentralized mode of operation and the aim of this work is implementation of controlling and diagnostic mechanism into an electric scooter project realized at Technical university of Ostrava. In todays world which now fully enjoys the prime of electromobility, off-grid battery systems and other, it is important to seek the optimal balance between functionality and the economy side of BMS that being electronics which deals with secondary cells of batery packs. There were numerous sophisticated, but not too practical BMS models in the past, such as centralized system or standalone balance modules of individual cells. This article aims at development of standalone balance modules which are able to communicate with the coordinator, adjust their parameters and ensure their cells safety in case of a communication failure. With the current worldwide cutting cost trend in mind, the emphasis was put on the lowest price possible for individual component. The article is divided into two major categories, the first one being desing of power electronics with emphasis on quality, safety (cooling) and also cost. The second part describes development of a communication interface with reliability and cost in mind. The article contains numerous graphs from practical measurements. The outcome of the work and its possible future is defined in the conclusion.

    Various studies show that raising the temperature as well as storms, cold snap, raining and drought caused by climate change. And variety disasters have had a damage to mankind. The world risk report(2012, The Nature Conservancy) and UNU-EHS (the United Nations University Institute for Environment and Human Security) reported that more and more people are exposed to abnormal weather such as floods, drought, earthquakes, typhoons and hurricanes over the world. In particular, the case of Korea, we influenced by various pollutants which are occurred in Northeast Asian countries, China and Japan, due to geographical meteorological characteristics. These contaminants have had a significant impact on air quality with the pollutants generated in Korea. Recently, around the world continued their effort to reduce greenhouse gas and to improve air quality in conjunction with the national or regional development goals priority. China is also working on various efforts in accordance with the international flows to cope with climate change and air pollution. In the future, effect of climate change and air quality in Korea and Northeast Asia will be change greatly according to China's growth and mitigation policies. The purpose of this study is to minimize the damage caused by climate change on the Korean peninsula through an integrated approach taking into account the mitigation and adaptation plan. This study will suggest a climate change strategy at the national level by means of a comprehensive economic analysis of the impacts and mitigation of climate change. In order to quantify the impact and damage cost caused by climate change scenarios in a regional scale, it should be priority variables selected in accordance with impact assessment of climate change. The sectoral impact assessment was carried out on the basis of selected variables and through this, to derive the methodology how to estimate damage cost and adaptation cost. And then, the methodology was applied in Korea

  13. Environmental taxes and transaction costs

    International Nuclear Information System (INIS)

    Vollebergh, Herman R.J.

    1994-06-01

    A well-known tax policy principle in the case of environmental bads holds that optimality would apply to a special class of environmental taxes, the so called Pigovian or effluent taxes (or fees or charges). However, an interesting paradox arises here for effluent taxes are seldom chosen in practical policies by governments. An explanation for this discrepancy is that effluent taxes are generally supposed to bring about the highest amount of transaction costs in order to enforce this kind of tax. This would be caused by the fact that usually large numbers of agents are involved if effluents are taken as the principal tax base. Unfortunately this explanation seems to boomerang for it brings about an impossibility result: effluent taxes can never be first best taxes if transaction costs are allowed. Up till now theoretical economics has not paid much attention to this problem. In contrast this essay offers an explanation for the discrepancy and it shows why the impossibility theorem is a paradox. As soon as one allows for transaction costs in welfare analysis, one not only has to acknowledge that such costs are attached to the internalization device but also to the initial status quo. Moreover, the amount of transaction costs is not independent of the tax contracts themselves, neither are the benefits of regulation through taxation. Accordingly a more general welfare assessment of questions where it is optimal to levy environmental taxes shows that first best Pigovian taxes need not be effluent taxes (even if abatement is possible), although in some cases effluent taxes might still be the best policy option from an economic perspective. 31 refs

  14. The ITER reduced cost design

    International Nuclear Information System (INIS)

    Aymar, R.

    2000-01-01

    Six years of joint work under the international thermonuclear experimental reactor (ITER) EDA agreement yielded a mature design for ITER which met the objectives set for it (ITER final design report (FDR)), together with a corpus of scientific and technological data, large/full scale models or prototypes of key components/systems and progress in understanding which both validated the specific design and are generally applicable to a next step, reactor-oriented tokamak on the road to the development of fusion as an energy source. In response to requests from the parties to explore the scope for addressing ITER's programmatic objective at reduced cost, the study of options for cost reduction has been the main feature of ITER work since summer 1998, using the advances in physics and technology databases, understandings, and tools arising out of the ITER collaboration to date. A joint concept improvement task force drawn from the joint central team and home teams has overseen and co-ordinated studies of the key issues in physics and technology which control the possibility of reducing the overall investment and simultaneously achieving the required objectives. The aim of this task force is to achieve common understandings of these issues and their consequences so as to inform and to influence the best cost-benefit choice, which will attract consensus between the ITER partners. A report to be submitted to the parties by the end of 1999 will present key elements of a specific design of minimum capital investment, with a target cost saving of about 50% the cost of the ITER FDR design, and a restricted number of design variants. Outline conclusions from the work of the task force are presented in terms of physics, operations, and design of the main tokamak systems. Possible implications for the way forward are discussed

    1979-12-01

    This report estimates current and future costs associated with the light water reactor nuclear fuel cycle for both once-through and thermal recycle cases. Using a range of future nuclear power generating scenarios, process flows are developed for each segment of the nuclear fuel cycle. Capital and operating costs are estimated and are combined with the process flows to generate unit cost projections for each fuel cycle segment. The unit costs and process flows are combined in the NUCOST program to estimate fuel cycle power costs through the year 2020. The unit costs are also used to estimate the fuel costs of an individual model PWR and BWR.

  15. Food irradiation : estimates of cost of processing

    International Nuclear Information System (INIS)

    Krishnamurthy, K.; Bongirwar, D.R.

    1987-01-01

    For estimating the cost of food irradiation, three factors have to be taken into consideration. These are : (1) capital cost incurred on irradiation device and its installation, (2) recurring or running cost which includes maintenance cost and operational expenditure, and (3) product specific cost dependent on the factors specific to the food item to be processed, its storage, handling and distribution. A simple method is proposed to provide estimates of capital costs and running costs and it is applied to prepare a detailed estimate of costs for irradiation processing of onions and fish in India. The cost of processing onions worked out to be between Rs. 40 to 120 per 1000 Kg and for fish Rs 354 per 1000 Kg. These estimates do not take into account transparation costs and fluctuations in marketing procedures. (M.G.B.). 7 tables

    A basic assumption of the gravity equation of international trade is that increasing trade costs lower exports. Butintuition and theory imply that a high export volume lowers bilateral trade costs as well, because a fixed cost intensivetrade sector probably bears lower average costs with more trade. In this case, standard gravity estimation might bebiased due to simultaneity. This paper finds an empirical interdependency between exports and trade costs.

    With the end of the cold war, funding for the Environmental Management program increased rapidly as nuclear weapons production facilities were shut down, cleanup responsibilities increased, and facilities were transferred to the cleanup program. As funding for the Environmental Management (EM) program began to level off in response to Administration and Congressional efforts to balance the Federal budget, the program redoubled its efforts to increase efficiency and get more productivity out of every dollar. Cost savings and enhanced performance are an integral pair of Hanford Site operations. FY1997 was the third year of a cost savings program that was initially defined in FY 1995. The definitions and process remained virtually the same as those used in FY 1996.

    The first part of the 2003 study of reference costs for power generation has been completed. It was carried out by the General Directorate for Energy and Raw Materials (DGEMP) of the French Ministry of the Economy, Finance and Industry, with the collaboration of power-plant operators, construction firms and many other experts. A Review Committee of experts including economists (Forecasting Department, French Planning Office), qualified public figures, representatives of power-plant construction firms and operators, and non-governmental organization (NGO) experts, was consulted in the final phase. The study examines the costs of power generated by different methods (i.e. nuclear and fossil-fuel [gas-, coal-, and oil-fired] power plants) in the context of an industrial operation beginning in the year 2015. - The second part of the study relating to decentralized production methods (wind, photovoltaic, combined heat and power) is still in progress and will be presented at the beginning of next year. - 1. Study approach: The study is undertaken mainly from an investor's perspective and uses an 8% discount rate to evaluate the expenses and receipts from different years. In addition, the investment costs are considered explicitly in terms of interest during construction. - 2. Plant operating on a full-time basis (year-round): The following graph illustrates the main conclusions of the study for an effective operating period of 8000 hours. It can be seen that nuclear is more competitive than the other production methods for a year-round operation with an 8% discount rate applied to expenses. This competitiveness is even better if the costs related to greenhouse-gas (CO 2 ) emission are taken into account in estimating the MWh cost price. Integrating the costs resulting from CO 2 emissions by non-nuclear fuels (gas, coal), which will be compulsory as of 2004 with the transposition of European directives, increases the total cost per MWh of these power generation methods

    The Office of Management and Budget (OMB) and the U.S. Army Corps of Engineers have completed an analysis of the Department of Energy's (DOE) Fiscal Year (FY) 1993 budget request for its Environmental Restoration and Waste Management (ERWM) program. The results were presented to an interagency review group (IAG) of senior-Administration officials for their consideration in the budget process. This analysis included evaluations of the underlying legal requirements and cost estimates on which the ERWM budget request was based. The major conclusions are contained in a separate report entitled, ''Interagency Review of the Department of Energy Environmental Restoration and Waste Management Program.''

    This paper discusses the cost implications of the air pollution abatement recommendations contained in a recently published IPSEP (International Project for Sustainable Energy Paths) study on the feasibility of the abatement of carbon dioxide emissions deemed significantly responsible for the greenhouse effect and its associated negative impacts on this planet's climatic equilibrium. The air pollution abatement strategies are to be enforced in five highly industrialized European countries - Germany, France, Great Britain, Italy and Holland. The study's overall results indicate the feasibility of 50% reductions in carbon dioxide emissions within the next 30 years even with a more than doubling of GNP's and a contemporaneous phase-out of nuclear power production, and all this taking place in a cost effective way and with increased employment. In addition, IPSEP's report states that the implementation of effective program management strategies would bolster Western Europe's competitiveness on a global scale

    The present paper discusses briefly the many factors, including capital cost, which have to be taken into account in determining whether a series of power stations based on a small nuclear plant can be competitive with a series based on traditional large unit sizes giving the guaranteed level of supply. The 320 MWe UK/US Safe Integral Reactor is described as a good example of how the factors discussed can be beneficially incorporated into a design using proven technology. Finally it goes on to illustrate how the overall costs of a generating system can indeed by reduced by use of the 320 MWe Safe Integral Reactor rather than conventional units of around 1200 MWe.

    When evaluating new investment projects, oil companies traditionally use the discounted cashflow method. This method requires expected cashflows in the numerator and a risk adjusted required rate of return in the denominator in order to calculate net present value. The capital expenditure (CAPEX) of a project is one of the major cashflows used to calculate net present value. Usually the CAPEX is given by a single cost figure, with some indication of its probability distribution. In the oil industry and many other industries, it is common practice to report a CAPEX that is the estimated 50/50 (median) CAPEX instead of the estimated expected (expected value) CAPEX. In this article we demonstrate how the practice of using a 50/50 (median) CAPEX, when the cost distributions are asymmetric, causes project valuation errors and therefore may lead to wrong investment decisions with acceptance of projects that have negative net present values.

    Countries with considerable PhotoVoltaic (PV) installations are facing a challenge of overloading their power grid during peak-power production hours if the power infrastructure remains the same. To address this, regulations have been imposed on PV systems, where more active power control should...... be flexibly performed. As an advanced control strategy, the Absolute Active Power Control (AAPC) can effectively solve the overloading issues by limiting the maximum possible PV power to a certain level (i.e., the power limitation), and also benefit the inverter reliability due to the reduction in the thermal...... loading of the power devices. However, its feasibility is challenged by the associated energy losses. An increase of the inverter lifetime and a reduction of the energy yield can alter the cost of energy, demanding an optimization of the power limitation. Therefore, aiming at minimizing the Levelized Cost...

    Litigation imposes large costs on society; this justifies settlement considerations. In any case, access to justice is critical to socioeconomic development; as such, it needs to be balanced with litigation minimization. This study examines the tradeoff between litigation and access to justice and explicitly elucidates their relationship. In considering access issues, this study finds that the outcomes of policies that affect parties’ litigation decisions partially depart from those in the st...

    We construct a model where money and credit are alternative payment instruments, use it to analyze sluggish nominal prices, and confront the data. Equilibria entail price dispersion, where sellers set nominal terms that they may keep fixed when aggregate conditions change. Buyers use cash and credit, with the former (latter) subject to inflation (transaction costs). We provide strong analytic results and exact solutions for money demand. Calibrated versions match price-change data well, with ...

    I study the choice of economic transparency in a heterogeneous-information model where agents must pay a cost to observe the announcements of an information authority. The authority chooses transparency by selecting the number of signals regarding an aggregate state to make public, and agents respond by choosing how many of those signals to observe. I show that, when agents seek to coordinate their actions, the amount of information actually gathered by agents is non-monotonic in the transpar...

  10. Environmental costs of mercury pollution.

    2006-09-01

    Mercury (Hg) has been used for millennia in many applications, primarily in artisanal mining and as an electrode in the chlor-alkali industry. It is anthropogenically emitted as a pollutant from coal fired power plants and naturally emitted, primarily from volcanoes. Its unique chemical characteristics enable global atmospheric transport and it is deposited after various processes, ultimately ending up in one of its final sinks, such as incorporated into deep sediment or bioaccumulated, primarily in the marine environment. All forms of Hg have been established as toxic, and there have been no noted biological benefits from the metal. Throughout time, there have been notable incidents of Hg intoxication documented, and the negative health effects have been documented to those chronically or acutely exposed. Today, exposure to Hg is largely diet or occupationally dependent, however, many are exposed to Hg from their amalgam fillings. This paper puts a tentative monetary value on Hg polluted food sources in the Arctic, where local, significant pollution sources are limited, and relates this to costs for strategies avoiding Hg pollution and to remediation costs of contaminated sites in Sweden and Japan. The case studies are compiled to help policy makers and the public to evaluate whether the benefits to the global environment from banning Hg and limiting its initial emission outweigh the benefits from its continued use or lack of control of Hg emissions. The cases we studied are relevant for point pollution sources globally and their remediation costs ranged between 2,500 and 1.1 million US dollars kg(-1) Hg isolated from the biosphere. Therefore, regulations discontinuing mercury uses combined with extensive flue gas cleaning for all power plants and waste incinerators is cost effective.

    1993-05-01

    The purpose of this paper is to examine some of the systems and sub-systems involved in so-called ''conventional'' e + e - linear colliders and to study how their design affects the overall cost of these machines. There are presently a total of at least six 500 GeV c. of m. linear collider projects under study in the world. Aside from TESLA (superconducting linac at 1.3 GHz) and CLIC (two-beam accelerator with main linac at 30GHz), the other four proposed e + e - linear colliders can be considered ''conventional'' in that their main linacs use the proven technique of driving room temperature accelerator sections with pulsed klystrons and modulators. The centrally distinguishing feature between these projects is their main linac rf frequency: 3 GHz for the DESY machine, 11.424 GHz for the SLAC and JLC machines, and 14 GHz for the VLEPP machine. The other systems, namely the electron and positron sources, preaccelerators, compressors, damping rings and final foci, are fairly similar from project to project. Probably more than 80% of the cost of these linear colliders will be incurred in the two main linacs facing each other and it is therefore in their design and construction that major savings or extra costs may be found

    The optimization of radiological protection will routinely involve the balancing of public and occupational exposure, particularly within the nuclear fuel cycle. For example the reduction of public exposure from an effluent stream could lead to increases in occupational exposure from treatment, storage and disposal operations. A methodology is propased for the estimation of the cost of occupational exposure in the UK (Pound man-Sv -1 ) based on valuations of changes in risk. A variable value for the cost of the occupational man-Sv is obtained depending on per caput dose levels. The values at particular per caput dose levels are different for occupational workers and the general public, because of different demography and assumptions on risk perception and aversion. They are however approximately the same when the per caput doses are expressed as percentages of the dose limits for workers and the general public respectively. An example of the application of the derived cost of the occupational man-Sv to an optimisation problem is given. (author)

  16. Empathic concern drives costly altruism

    2015-01-01

    Why do we self-sacrifice to help others in distress? Two competing theories have emerged, one suggesting that prosocial behavior is primarily motivated by feelings of empathic other-oriented concern, the other that we help mainly because we are egoistically focused on reducing our own discomfort. Here we explore the relationship between costly altruism and these two sub-processes of empathy, specifically drawing on the caregiving model to test the theory that trait empathic concern (e.g. general tendency to have sympathy for another) and trait personal distress (e.g. predisposition to experiencing aversive arousal states) may differentially drive altruistic behavior. We find that trait empathic concern – and not trait personal distress – motivates costly altruism, and this relationship is supported by activity in the ventral tegmental area, caudate and subgenual anterior cingulate, key regions for promoting social attachment and caregiving. Together, this data helps identify the behavioral and neural mechanisms motivating costly altruism, while demonstrating that individual differences in empathic concern-related brain responses can predict real prosocial choice.

    1989-01-01

    One of the consequences of the privatization of the Central Electricity Generating Board has been a weakening of the economic case for nuclear generation over coal. Nuclear has higher capital, but lower operating costs than coal and is therefore favoured in capital budgeting by discounting at lower rates of return. In the Sizewell case (in 1987), discounting at the public sector rate of 5 per cent favoured nuclear. However, the private sector will require higher rates of return, thus rendering nuclear less attractive. Hence the imposition by the government of a diversity constraint on the privatized industry to ensure that contracts are made for a minimum fraction of non-fossil (essentially nuclear) energy. An electricity capacity planning model was developed to estimate the costs of imposing various non-fossil energy constraints on the planning decision of a privatized electricity supply industry, as a function of various discount rates. Using a large-scale linear programming technique, the model optimizes over a 50 year horizon the schedule of installation, and mix of generating capacity, both with and without a minimum non-fossil constraint. The conclusion is that the opportunity cost of diversity may be a complex joint substation of more than one type of plant (eg coal and gas) depending on the discount rate. (author)

  18. Communication cost of entanglement transformations

    Hayden, Patrick; Winter, Andreas

    2003-01-01

    We study the amount of communication needed for two parties to transform some given joint pure state into another one, either exactly or with some fidelity. Specifically, we present a method to lower bound this communication cost even when the amount of entanglement does not increase. Moreover, the bound applies even if the initial state is supplemented with unlimited entanglement in the form of EPR (Einstein-Podolsky-Rosen) pairs and the communication is allowed to be quantum mechanical. We then apply the method to the determination of the communication cost of asymptotic entanglement concentration and dilution. While concentration is known to require no communication whatsoever, the best known protocol for dilution, discovered by H.-K. Lo and S. Popescu [Phys. Rev. Lett. 83, 1459 (1999)], requires exchange of a number of bits that is of the order of the square root of the number of EPR pairs. Here we prove a matching lower bound of the same asymptotic order, demonstrating the optimality of the Lo-Popescu protocol up to a constant factor and establishing the existence of a fundamental asymmetry between the concentration and dilution tasks. We also discuss states for which the minimal communication cost is proportional to their entanglement, such as the states recently introduced in the context of 'embezzling entanglement' (W. van Dam and P. Hayden, e-print quant-ph/0201041)

  19. Hospital cost accounting and the new imperative.

    1987-05-01

    Government regulatory structures, prospective payment mechanisms, a more competitive environment, and attempts to link cost accounting principles to planning, budgeting, and fiscal control all have served as catalysts for hospitals to increase their reliance and emphasis on cost accounting. Current hospital accounting systems are relatively inexpensive to develop and maintain, and they fulfill the financial reporting requirements mandated by Medicare and other third-party payers. These systems, however, do not provide information on what specific service units cost, and managers must have this information to make optimal trade-offs between quality, availability, and cost of medical services. Most health care organizations have a predetermined charge for each type of service, but the charge may not accurately portray the cost of providing the service. Knowing true costs will enable managers to select the most cost-effective method of treating a patient; know the financial implications of adding tests or procedures; relate costs to established norms of care; establish ranges of acceptable costs in various diagnostic groups; negotiate more successfully with rate review organizations and health maintenance organizations; and vigorously market and advertise the services that most contribute to the organization's overall financial health. The goal of microcosting is to determine the full cost of providing specific service units. The microcosting process comprises three components: data collection, cost modeling, and cost analysis. Microcosting is used to determine full costs for 20 percent of the hospital's procedures that are responsible for generating 80 percent of the hospital's gross revenue. Full costs are established by adding labor costs, materials costs, equipment depreciation costs, departmental overhead costs, and corporate overhead costs.(ABSTRACT TRUNCATED AT 250 WORDS)
