    Crude glycerol is a low-value byproduct which is primarily obtained from the biodiesel production process. Its composition is significantly different from that of pure glycerol. Crude glycerol usually contains various impurities, such as water, methanol, soap, fatty acids, and fatty acid methyl esters. Considerable efforts have been devoted to finding applications for converting crude glycerol into high-value products, such as biofuels, chemicals, polymers, and animal feed, to improve the economic viability of the biodiesel industry and overcome environmental challenges associated with crude glycerol disposal. This article reviews recent advances of biological and chemical technologies for value-added processing of crude glycerol into chemicals and polymers, and provides strategies for addressing production challenges.

    With approximately 1.3 billion tonnes of food wasted per annum, food supply chain wastes (FSCWs) may be viewed as the contemporary Periodic Table of biobased feedstock chemicals (platform molecules) and functional materials. Herein, the global drivers and case for food waste valorisation within the context of global sustainability, sustainable development goals and the bioeconomy are discussed. The emerging potential of high value added chemicals from certain tropical FSCW is considered as these are grown in three major geographical areas: Brazil, India and China, and likely to increase in volume. FSCW in the context of biorefineries is discussed and two case studies are reported, namely: waste potato, and; orange peel waste. Interestingly, both waste feedstocks, like many others, produce proteins and with the global demand for vegetable proteins on the rise then proteins from FSCW may become a dominant area.

    Transforming plant biomass to biofuel is one of the few solutions that can truly sustain mankind's long-term needs for liquid transportation fuel with minimized environmental impact. However, despite decades of effort, commercial development of biomass-to-biofuel conversion processes is still not an economically viable proposition. Identifying value-added co-products along with the production of biofuel provides a key solution to overcoming this economic barrier. Lignin is the second most abundant component next to cellulose in almost all plant biomass; the emerging biomass refinery industry will inevitably generate an enormous amount of lignin. Development of selective biorefinery lignin-to-bioproducts conversion processes will play a pivotal role in significantly improving the economic feasibility and sustainability of biofuel production from renewable biomass. The urgency and importance of this endeavor has been increasingly recognized in the last few years. This paper reviews state-of-the-art oxidative lignin depolymerization chemistries employed in the papermaking process and oxidative catalysts that can be applied to biorefinery lignin to produce platform chemicals including phenolic compounds, dicarboxylic acids, and quinones in high selectivity and yield. The potential synergies of integrating new catalysts with commercial delignification chemistries are discussed. We hope the information will build on the existing body of knowledge to provide new insights towards developing practical and commercially viable lignin conversion technologies, enabling sustainable biofuel production from lignocellulosic biomass to be competitive with fossil fuel. © 2015 WILEY-VCH Verlag GmbH & Co.

    This work is part of a series of investigations on pyrolysis of lignin. After obtaining the necessary information regarding the quantity and quality of the obtained products, a first step economics evaluation for converting lignin into chemicals was essential. To accomplish this aim, a pyrolysis plant with a 50t/d capacity was designed, and the total capital investment and operating costs were estimated. Next, the minimal selling price of the obtained dry oil was calculated and the effect of crucial variables on the estimated price was examined. The key result indicates the estimated selling price would not compete with the price of the chemicals that are fossil fuel based, which is primarily due to the high cost of the feedstock. To overcome this challenge, different scenarios for reducing the selling price of the obtained oil, which consequently is helping by taking a place among the fossil fuel based chemicals, were discussed.

    This report describes results toward developing a process to sequester CO{sub 2} centered on the enzymes PEP carboxylase and pyruvate carboxylase. The process involves the use of bacteria to convert CO{sub 2} and glucose as a co-substrate and generates succinic acid as a commodity chemical product. The study reports on strain development and process development. In the area of strain development, knockouts in genes which divert carbon from the enzymatic steps involved in CO{sub 2} consumption were completed, and were shown not to affect significantly the rate of CO{sub 2} sequestration and succinic acid generation. Furthermore, the pyc gene encoding for pyruvate carboxylase proved to be unstable when integrated onto the chromosome. In the area of process development, an optimal medium, pH and base counterion were obtained, leading to a sequestration rate as great as 800 mg/Lh. Detailed studies of gas phase composition demonstrated that CO{sub 2} composition has a significant affect on CO{sub 2} sequestration, while the presence of 'toxic' compounds in the gas, including NO{sub 2}, CO and SO{sub 2} did not have a detrimental effect on sequestration. Some results on prolonging the rate of sequestration indicate that enzyme activities decrease with time, suggesting methods to prolong enzyme activity may benefit the overall process.

    Lignocellulosic biomass is an abundant renewable resource and can be efficiently converted into bio-energy by a bio-refinery. From the various techniques available for biomass thermo-chemical conversion; microwave assisted pyrolysis (MAP) seems to be the very promising. The principles of microwave technology were reviewed and the parameters for the efficient production of bio-oil using microwave technology were summarized. Microwave technology by itself cannot efficiently produce high quality bio-oil products, catalysts are used to improve the reaction conditions and selectivity for valued products during MAP. The catalysts used to optimize MAP are revised in the development of this article. The origins for bio-oils that are phenol rich or hydrocarbon rich are reviewed and their experimental results were summarized. The kinetics of MAP is discussed briefly in the development of the article. Future prospects and scientific development of MAP are also considered in the development of this article.

    In recent decades, the substitution of non-renewable fossil resources by renewable biomass as a sustainable feedstock has been extensively investigated for the manufacture of high value-added products such as biofuels, commodity chemicals, and new bio-based materials such as bioplastics. Numerous solid catalyst systems for the effective conversion of biomass feedstocks into value-added chemicals and fuels have been developed. Solid catalysts are classified into four main groups with respect to their structures and substrate activation properties: (a) micro- and mesoporous materials, (b) metal oxides, (c) supported metal catalysts, and (d) sulfonated polymers. This review article focuses on the activation of substrates and/or reagents on the basis of groups (a)-(d), and the corresponding reaction mechanisms. In addition, recent progress in chemocatalytic processes for the production of five industrially important products (5-hydroxymethylfurfural, lactic acid, glyceraldehyde, 1,3-dihydroxyacetone, and furan-2,5-dicarboxylic acid) as bio-based plastic monomers and their intermediates is comprehensively summarized.

    Diminishing fossil fuel reserves and mounting environmental concerns associated with petrochemical manufacturing practices have generated significant interests in developing whole-cell biocatalytic systems for the production of value-added chemicals and biofuels. Although acetyl-CoA is a common natural biogenic precursor for the biosynthesis of numerous metabolites, propionyl-CoA is unpopular and non-native to most organisms. Nevertheless, with its C3-acyl moiety as a discrete building block, propionyl-CoA can serve as another key biogenic precursor to several biological products of industrial importance. As a result, engineering propionyl-CoA metabolism, particularly in genetically tractable hosts with the use of inexpensive feedstocks, has paved an avenue for novel biomanufacturing. Herein, we present a systematic review on manipulation of propionyl-CoA metabolism as well as relevant genetic and metabolic engineering strategies for microbial production of value-added chemicals and biofuels, including odd-chain alcohols and organic acids, bio(co)polymers and polyketides.

    Over 8 million tonnes of sugar beet are grown annually in the UK. Sugar beet pulp (SBP) is the main by-product of sugar beet processing which is currently dried and sold as a low value animal feed. SBP is a rich source of carbohydrates, mainly in the form of cellulose and pectin, including d-glucose (Glu), l-arabinose (Ara) and d-galacturonic acid (GalAc). This work describes the technical feasibility of an integrated biorefinery concept for the fractionation of SBP and conversion of these monosaccharides into value-added products. SBP fractionation is initially carried out by steam explosion under mild conditions to yield soluble pectin and insoluble cellulose fractions. The cellulose is readily hydrolysed by cellulases to release Glu that can then be fermented by a commercial yeast strain to produce bioethanol at a high yield. The pectin fraction can be either fully hydrolysed, using physico-chemical methods, or selectively hydrolysed, using cloned arabinases and galacturonases, to yield Ara-rich and GalAc-rich streams. These monomers can be separated using either Centrifugal Partition Chromatography (CPC) or ultrafiltration into streams suitable for subsequent enzymatic upgrading. Building on our previous experience with transketolase (TK) and transaminase (TAm) enzymes, the conversion of Ara and GalAc into higher value products was explored. In particular the conversion of Ara into l-gluco-heptulose (GluHep), that has potential therapeutic applications in hypoglycaemia and cancer, using a mutant TK is described. Preliminary studies with TAm also suggest GluHep can be selectively aminated to the corresponding chiral aminopolyol. The current work is addressing the upgrading of the remaining SBP monomer, GalAc, and the modelling of the biorefinery concept to enable economic and Life Cycle Analysis (LCA).

  20. Exploring green catalysts for production of biofuels and value added chemicals for renewable and sustainable energy future

    Porous silica have attracted significant attention in the past few decades due to their unique textural properties. They were extensively investigated for applications in catalysis, separation, environmental remediation and drug delivery. We have investigated the porous metal incorporated silica in the synthetic as well as catalytic perspectives. The synthesis of metal incorporated mesoporous silica via co-condensation such as SBA-15, KIT-5 are still challenging as it involves acidic synthetic route. Synthesis in high acidity conditions affects the incorporation of metal in silica due to high dissolution of metal precursors and breaking of metal oxygen and silica bond. The research presented here demonstrates an efficient way to incorporate metals by addition of diammonium hydrogen phosphate along with metal precursor during the synthesis. The incorporation efficiency has increased 2-3 times with this approach. Catalytic studies were performed to support our hypothesis. Such synthesized molybdenum incorporated mesoporous silica were investigated as catalyst for fast pyrolysis. When molydenum incorporated in silica was used as catalyst for fast pyrolysis of pine, it selectively produced furans (furan, methylfuran and dimethylfuran). Furans are considered value-added chemicals and can be used as a blendstock for diesel/jet grade fuel. The catalyst was very stable to harsh pyrolysis conditions and had a longer life before deactivation when compared with traditional zeolites. Further, this catalyst did not produce aromatic hydrocarbons in significant yields unlike zeolites. The origin of the furans was determined to be biopolymer cellulose and the selectivity for furans are attributed to low catalyst acidity. The effect of silica to alumina ratio (SAR) of beta-zeolite was investigated ranging to elucidate the relationship between the of number of acid sites on product speciation and catalyst deactivation on catalysts supplied by Johnson Matthey. The catalyst with low

    One of the major ecological concerns associated with biodiesel production is the generation of waste/crude glycerol during the trans-esterification process. Purification of this crude glycerol is not economically viable. In this context, the development of an efficient and economically viable strategy would be biotransformation reactions converting the biodiesel derived crude glycerol into value added chemicals. Hence the process ensures the sustainability and waste management in biodiesel industry, paving a path to integrated biorefineries. This review addresses a waste to wealth approach for utilization of crude glycerol in the production of value added chemicals, current trends, challenges, future perspectives, metabolic approaches and the genetic tools developed for the improved synthesis over wild type microorganisms were described.

    Highlights: • Sample collection, isolation and identification to obtain a pure microalgal species. • Isolation of microalgal strains worldwide based on continent and habitat. • Genetic engineering tools for enhanced production of biodiesel and value added chemicals. • Cultivation systems for genetically modified strain. - Abstract: Microalgae and cyanobacteria are promising sources of biodiesel because of their high oil content (∼10 fold higher) and shorter cultivation time (∼4 fold lesser) than conventional oil producing territorial plants (e.g., soybean, corn and jatropha). These organisms also provide source of several valuable natural chemicals including pigments, food supplements like eicosapentanoic acid [EPA], decosahexaenoic acid [DHA] and vitamins. In addition, many cellular components of these organisms are associated with therapeutic properties like antioxidant, anti-inflammatory, immunostimulating, and antiviral. Isolation and identification of high-yielding strains with the faster growth rate is the key for successful implementation of algal biodiesel (or other products) at a commercial level. A number of research groups in Europe, America, and Australia are thus extensively involved in exploration of novel microalgal strain. Further, genetic engineering provides a tool to engineer the native strain resulting in transgenic strain with higher yields. Despite these efforts, no consensus has yet been reached so far in zeroing on the best microalgal strain for sustainable production of biofuel at reasonable cost. The search for novel microalgal strain and transgenesis of microalgae, are continuing side by side with the hope of commercial scale production of microalgae biofuel in near future. However, no consolidated review report exists which guides to isolate and identify a uncontaminated microalgal strain along with their transgenesis. The present review is focused on: (i) key factors for sample collection, isolation, and identification to

Organoleptic and physico-chemical evaluation of capretto baladi goats: a value-added meat alternative in an extensive rearing system. Lebanese Science Journal. 18(1: 73-80. The local Baladi breed is considered a common source of fresh meat in Lebanon. Due to the extensive rearing system and the scarcity of pasture, kids resulting from multiple births are not reared, though cultural preference for young meat may valorize these twin kids as an expensive delicacy. Few studies observed growth parameters, physical-chemical and sensory properties of meat in Baladi kids. Therefore, 24 male Baladi kids were fed milk ad libitum post-natally for 24 days, after which 9 were randomly selected and fed pasture grass ad libitum and goat milk (Control, and 15 were fed only milk (Capretto twice per day. Animals were slaughtered at 4, 6 and 8 weeks of age and body organs compared. Feed intake was measured by weighing kids pre- and post- feeding, and body weight measured twice per week. Meat chemical properties were total ether-extracted fat, kjeldhal protein, and minerals. Meat organoleptic properties were evaluated by consumers for color, taste, odor, richness, juiciness, tenderness and overall appreciation, as cooked by housewives or professionals. Data were analyzed as a CRD using SPSS 10.0 and presented as LSMeans ± SEM. Results showed that Capretto consumed increasing levels of milk from 4 to 8 weeks, with ADG decreasing (P 0.05 between Capretto and control, although capretto showed lower (p<0.05 meat fat content than control kids. Meat organoleptic characteristics were desirable at weeks 4 and 6 for both Capretto and control kids, whereas only Capretto meat stayed desirable at week 8. To conclude, Capretto kids have similar properties to their traditional counterparts, with added desirable properties for a longer growing period, in addition to the increased health benefit of lower fat content.

    The conventional premise that metrology is a "non-value-added necessary evil" is a misleading and dangerous assertion, which must be viewed as obsolete thinking. Many metrology applications are key enablers to traditionally labeled "value-added" processing steps in lithography and etch, such that they can be considered integral parts of the processes. Various key trends in modern, state-of-the-art processing such as optical proximity correction (OPC), design for manufacturability (DFM), and advanced process control (APC) are based, at their hearts, on the assumption of fine-tuned metrology, in terms of uncertainty and accuracy. These trends are vehicles where metrology thus has large opportunities to create value through the engineering of tight and targetable process distributions. Such distributions make possible predictability in speed-sorts and in other parameters, which results in high-end product. Additionally, significant reliance has also been placed on defect metrology to predict, improve, and reduce yield variability. The necessary quality metrology is strongly influenced by not only the choice of equipment, but also the quality application of these tools in a production environment. The ultimate value added by metrology is a result of quality tools run by a quality metrology team using quality practices. This paper will explore the relationships among present and future trends and challenges in metrology, including equipment, key applications, and metrology deployment in the manufacturing flow. Of key importance are metrology personnel, with their expertise, practices, and metrics in achieving and maintaining the required level of metrology performance, including where precision, matching, and accuracy fit into these considerations. The value of metrology will be demonstrated to have shifted to "key enabler of large revenues," debunking the out-of-date premise that metrology is "non-value-added." Examples used will be from critical dimension (CD

    The local Baladi breed is considered a common source of fresh meat in Lebanon.Due to the extensive rearing system and the scarcity of pasture, kids resulting from multiple births are not reared, though cultural preference for young meat may valorize these twin kids as an expensive delicacy. Few studies observed growth parameters, physical-chemical and sensory properties of meat in Baladi kids. Therefore, 24 male Baladi kids were fed milk adlibitum post-natally for 24 days, after which 9 were randomly selected and fed pasture grassad libitum and goat milk (Control), and 15 were fed only milk (Capretto) twice per day. Animals were slaughtered at 4, 6 and 8 weeks of age and body organs compared. Feed intake wasmeasured by weighing kids pre- and post- feeding, and body weight measured twice per week.Meat chemical properties were total ether-extracted fat, kjeldhal protein, and minerals. Meat organoleptic properties were evaluated by consumers for color, taste, odor, richness, juiciness,tenderness and overall appreciation, as cooked by housewives or professionals. Data were analyzed as a CRD using SPSS 10.0 and presented as LSMeans ± SEM. Results showed that Capretto consumed increasing levels of milk from 4 to 8 weeks, with ADG decreasing (P<0.05) from 4 to 8 weeks. Capretto showed 5% less (P<0.05) weight than control kids. Carcass yield was higher (P< 0.05) for Capretto (44.5 ± 3.4 %) than control (36.3 ± 3.3%), with Capretto showing smaller viscera and lower hemoglobin. Both blood and meat (protein, cholesterol) composition did not differ (P>0.05) between Capretto and control, although capretto showed lower (p<0.05) meat fat content than control kids. Meat organoleptic characteristics were desirable at weeks 4 and 6 for both Capretto and control kids, whereas only Capretto meat stayed desirable at week 8. To conclude, Capretto kids have similar properties to their traditional counterparts, with added desirable properties for a longer growing period, in addition to

    Full Text Available The financial theory developed different categories of indicators - traditional and modern - in order to evaluate the firm’s value creation. The shareholders are directly interested by the value added in the company. The value creation is a complex process that implies correct decisions, common responsibility (managers and shareholders and actions towards an efficient and profitable activity. The traditional indicators of performance are not teoritically correlated with the the value creation and in these circumstances, should be used appropriate financial indicators in order to reflect the value of the company. Therefore, the modern indicators used in the value based management framework offer a greater flexibility and efficiency and represent a good alternative for companies. Such performance indicators used to measure the financial results correlated with shareholder wealth are the Economic Value Added (EVA, as a measure of internal performance and the Market Value Added (MVA as a measure of external performance of the company. Starting from the main deficiencies of the accounting indicators, the objective of this this study is to present the relationship between EVA and MVA and their implications on firms’valuation. Thus, the presentation and analysis of these indicators – EVA and MVA - will underline the main features, their correlations, and influence factors but also the main advantage and disadvantage of each indicator, which will enable the managers to make the correct choice and subsequently the best decision regarding the performance measures.

That is, as partners, rather than just clients. The key to success of any partnership is the goal that partners share in working together to add value to each other's business, sharing risks and rewards. This is a departure from AECL's traditional customer/supplier model. Forging partnerships requires establishing long-term relationships and setting long term performance goals. This means adjusting over time AECL's business processes, information technology, quality programs, and staffing resources to meet the changing needs of its clients. In light of this changing environment, AECL recently implemented a new operational structure, effective April 1, 2003. In this restructuring, five business units have been created, each focussing on key business offerings to its client base. The Services Business (SBU) is one of the units and will focus on providing value added services to AECL's partners. This paper will describe key elements of the new SBU and the themes that have influenced the design and organization and also provide an update on AECL's achievements in the Service Area. (author)

  4. Value Added Products from Renewable Biofuels

    Cellulosic ethanol is an emerging biofuel that will make strong contributions to American domestic energy needs. In the US midwest the standard method for pretreatment of biomass uses hot acid to deconstruct lignocellulose. While other methods work, they are not in common use. Therefore it is necessary to work within this context to achieve process improvements and reductions in biofuel cost. Technology underlying this process could supplement and even replace commodity enzymes with engineered microbes to convert biomass-derived lignocellulose feedstocks into biofuels and valueadded chemicals. The approach that was used here was based on consolidated bioprocessing. Thermoacidophilic microbes belonging to the Domain Archaea were evaluated and modfied to promote deconvolution and saccharification of lignocellulose. Biomass pretreatment (hot acid) was combined with fermentation using an extremely thermoacidophilic microbial platform. The identity and fate of released sugars was controlled using metabolic blocks combined with added biochemical traits where needed. LC/MS analysis supported through the newly established Nebraska Bioenergy Facility provided general support for bioenergy researchers at the University of Nebraska. The primary project strategy was to use microbes that naturally flourish in hot acid (thermoacidophiles) with conventional biomass pretreatment that uses hot acid. The specific objectives were: to screen thermoacidophilic taxa for the ability to deconvolute lignocellulose and depolymerize associated carbohydrates; evaluate and respond to formation of “inhibitors” that arose during incubation of lignocellulose under heated acidic conditions; identify and engineer “sugar flux channeling and catabolic blocks” that redirect metabolic pathways to maximize sugar concentrations; expand the hydrolytic capacity of extremely thermoacidophilic microbes through the addition of deconvolution traits; and establish the Nebraska Bioenergy Facility (NBF

    The Cloud Type (cldtype) value-added product (VAP) provides an automated cloud type classification based on macrophysical quantities derived from vertically pointing lidar and radar. Up to 10 layers of clouds are classified into seven cloud types based on predetermined and site-specific thresholds of cloud top, base and thickness. Examples of thresholds for selected U.S. Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) Climate Research Facility sites are provided in Tables 1 and 2. Inputs for the cldtype VAP include lidar and radar cloud boundaries obtained from the Active Remotely Sensed Cloud Location (ARSCL) and Surface Meteorological Systems (MET) data. Rain rates from MET are used to determine when radar signal attenuation precludes accurate cloud detection. Temporal resolution and vertical resolution for cldtype are 1 minute and 30 m respectively and match the resolution of ARSCL. The cldtype classification is an initial step for further categorization of clouds. It was developed for use by the Shallow Cumulus VAP to identify potential periods of interest to the LASSO model and is intended to find clouds of interest for a variety of users.

    Value added is a common tool in educational research on effectiveness. It is often modeled as a (prediction of a) random effect in a specific hierarchical linear model. This paper shows that this modeling strategy is not valid when endogeneity is present. Endogeneity stems, for instance, from a correlation between the random effect in the hierarchical model and some of its covariates. This paper shows that this phenomenon is far from exceptional and can even be a generic problem when the covariates contain the prior score attainments, a typical situation in value added modeling. Starting from a general, model-free definition of value added, the paper derives an explicit expression of the value added in an endogeneous hierarchical linear Gaussian model. Inference on value added is proposed using an instrumental variable approach. The impact of endogeneity on the value added and the estimated value added is calculated accurately. This is also illustrated on a large data set of individual scores of about 200,000 students in Chile.

    The objective of BIOVIRTA project is to develop technologies and practices with which digestates, originating from anaerobic digestion of different organic wastes and by-products, can be refined to value-added and safe products for various end-uses. It is expected that the operational preconditions for biogas plants will be significantly enhanced when the end-products are proven safe and applicable. Selection of the raw materials for anaerobic codigestion is the main operational strategy that could influence the nutrient content in the digestate. This has been clearly established in the laboratory and full-scale studies with various digestates originating from different raw materials, e.g. rendering and slaughterhouse byproducts. The nutrient content in the digestate also affects the opportunities to produce refined digestate products. In this project, the possibilities for several processing technologies, e.g. mechanical separation and stripping, have been intensively evaluated for the production of different digestate products. Their mass balances have also been estimated. The feasibility for the use of the digestate products has been assessed based on their chemical and hygienic quality and for various end-uses, including as organic fertiliser and/or soil improver in crop production. The preliminary results of these field-experiments showed that the yield of barley fertilised with digestate products was comparable to inorganic fertilisers. (orig.)

    Lane, Stephan; Dong, Jia; Jin, Yong-Su

    2018-04-07

    The substantial research efforts into lignocellulosic biofuels have generated an abundance of valuable knowledge and technologies for metabolic engineering. In particular, these investments have led to a vast growth in proficiency of engineering the yeast Saccharomyces cerevisiae for consuming lignocellulosic sugars, enabling the simultaneous assimilation of multiple carbon sources, and producing a large variety of value-added products by introduction of heterologous metabolic pathways. While microbial conversion of cellulosic sugars into large-volume low-value biofuels is not currently economically feasible, there may still be opportunities to produce other value-added chemicals as regulation of cellulosic sugar metabolism is quite different from glucose metabolism. This review summarizes these recent advances with an emphasis on employing engineered yeast for the bioconversion of lignocellulosic sugars into a variety of non-ethanol value-added products.

    Full Text Available Value added tax has been applied for four decades now and as a novelty it has already worn off both in theory and practice. It has indisputable advantages and relatively minor shortcomings compared to other forms of consumption taxation. Today it is one of the most widely used form of consumption tax in the world, being levied in about 120 countries accounting for around 70 per cent of the world population, including all European countries except Serbia and Bosnia and Herzegovina (the Federation and the Republic of Srpska. The burden of value added tax is visible at each stage in the production and distribution chain, thus eliminating taxation accumulation and is borne ultimately by the final consumer of final goods and services in the consuming country. The consumption type is a dominant type of value added tax. It ensures that the fixed and current assets purchases are exempt from VAT, and as such, it encourages technological progress and investment. By applying the country of destination principle (VAT is chargeable in the country where the goods or services are consumed - exports are exempt from tax while imports are taxed, value added tax eliminates double taxation and retains tax sovereignty of the importing country. In the last ten years there have been attempts to introduce value added tax in Serbia. The introduction of value added tax is the condition for the accession to the EU and we should expect that the latest attempt to introduce this tax in the Serbia taxation system will be successful. Namely, VAT Act is expected to be passed during 2004 and enforced as of January 1, 2005.

    Full Text Available The company's performance is mostly measured by analysis based on the financial ratio for a specific period. This type of measurement is highly dependent upon the accounting methods used in preparing the financial statement. Therefore a company's performance often looks good and improving overtime, but in reality its performance is deteriorating. The unreliable accounting measure needs an improved performance measure that will recognize and encourage management actions and strategies to increase the overall value of the company and ultimately to punish any activity that reduce value. The introduction of Economic Value Added (EVA has been very relevant recently because based on its definition, EVA measures the amount of value added created by specific action or strategy taken in a company. EVA is also used in the process of goal setting, capital budgeting, performance assessment, and most importantly, incentive compensation within a company. Its implication to the overall being of a company is so important these days that it should not be overlooked when companies plan their strategies.

    Full Text Available There is no doubt that conventional accounting does not provide actual value of a firm since they only take into account the tangible assets. Intellectual capital provides a new concept for considering actual value of the assets, which helps calculate intangible values of the firm. In this paper, we use value added intellectual coefficient (VAIC to measure the performance of a firm. The study investigates the relationship between intellectual capital and return on assets and value added for three consecutive years between 2008 and 2010. The results indicate that there is no meaningful relationship between intellectual capital and return on assets for fiscal years of 2008 and 2009 but there is a meaningful relationship between these two items for the fiscal year of 2010 when . Our findings also indicate that there is no meaningful relationship between intellectual capital and value added for the years of 2008 and 2010 but there is a meaningful relationship between the items for the fiscal year of 2009. The results somewhat confirm the recently published results in the literature, which argues the use of VAIC for assessing the direct impact of IC on other financial factors.

  19. Tax expenditures and the efficiency of Croatian value added tax

    2012-09-01

    Full Text Available The main aim of this paper is to provide a systematic overview of value added taxation in Croatia along with main changes in relevant legislation and to estimate total amount of tax expenditures. Results show that the proportion of tax expenditures in GDP in Croatia in 2010 amounted to less than 4%, a proportion lower than in any of the EU new member states, as well as almost twice as low as the EU-27 average. It can be concluded that the Croatian value added taxation system is efficient in this way, as was additionally shown by an analysis according to which Croatia in 2010 had better efficiency indicators than all the observed EU member states. The Croatian VAT system is mainly harmonized with EU directives, but abolition of the zero rate is still expected; this will increase government revenue by approximately 0.4-0.8% of GDP, depending on a chosen scenario. It has been suggested that a detailed analysis of the overall value added taxation system should be initiated, with the aim of optimizing cost-benefits. The main focus should be placed on the determination of the optimal VAT registration threshold, the costs and benefits of the introduced reliefs and exemptions in the tax system and the potential effects of the repeal of the zero rate.

  20. Sustainable Value Added as We Do Not Know It

    Full Text Available Entrepreneurial activities play an important role in a mixed economy. Incorporating the nowadays call for sustainable practices, enterprises cope with the evaluation of their efforts in the economic area as well as in the environmental area on their own. The method called Sustainable Value Added might very well solve this problem. It is based on the idea that enterprises actually create value when using environmental resources. However, opposite to the original idea, we do not think that environmental resources create the same value, never mind what resource we take. In this article, we propose the improvement of the original Sustainable Value Added arguing that the best for distinguishing various value creations is to weight the environmental resources according to their impact on environment. Based on an integrated analysis of the financial as well as environmental reports of selected German enterprises, we can conclude that when weighting environmental resources, enterprises performed worse than when simple averaged. However, the weighing reduces the risk of considering all resources to have the same impact on environment and on Sustainable Value Added results, as well.

    2015-08-30

    This report describes the Atmospheric Radiation Measurement (ARM) Best Estimate (ARMBE) 2-dimensional (2D) gridded surface data (ARMBE2DGRID) value-added product. Spatial variability is critically important to many scientific studies, especially those that involve processes of great spatial variations at high temporal frequency (e.g., precipitation, clouds, radiation, etc.). High-density ARM sites deployed at the Southern Great Plains (SGP) allow us to observe the spatial patterns of variables of scientific interests. The upcoming megasite at SGP with its enhanced spatial density will facilitate the studies at even finer scales. Currently, however, data are reported only at individual site locations at different time resolutions for different datastreams. It is difficult for users to locate all the data they need and requires extra effort to synchronize the data. To address these problems, the ARMBE2DGRID value-added product merges key surface measurements at the ARM SGP sites and interpolates the data to a regular 2D grid to facilitate the data application.

    Full Text Available Objective: Identify similarities and/or differences in the distribution of Value Added characterizing family businesses as opposed to non-family held firms, and analyse productivity by linking the distribution of the wealth generated by the company to a variety of related agents or stakeholders (employees, providers of loan capital, and shareholders. Design/methodology: A data series consisting of VA distribution in a sample of 8,609 Spanish companies, of which 5,109 are family firms and another 3,500 companies which are not, for the period comprising 2008 to 2013 was employed for this study. The data from the financial statements pertaining to these companies was taken from the SABI system (a privately-funded database analysing the financials of Spanish and Portuguese firms, operated by INFORMA, SA, selecting only those companies that employ standardized financial reporting practices. Findings and results: The work shows the existence of significant differences between family and non-family businesses in the distribution of value added among the different stakeholders. Given that, although both types of company spend most of the value added to remunerate staff, the family company spends a higher proportion thereof on self-financing as compared to non-family businesses, which spend a higher percentage on the remuneration of firm ownership. On the other hand, the lower labour productivity of family businesses is apparent, a result that can be explained both by the lower staff monetary remuneration, as well as the use of production technologies that are also less capital-intensive. Limitations: The study included only medium and large companies. These are companies that report financial statements offering more disaggregated data (through use of the standard forms. This owes to the legal requirement of these companies to file a cash flow statement, a necessary source for deriving information on dividends paid by the company. Added value: This is

    2012-01-01

    Full Text Available Increase in the value for the key stakeholders, i.e. shareholders, is one of the most important goals of a modern corporation. A new concept based on the value, so-called, Economic Value Added - EVA is a derived internal measure of value creation that helps managers in their decision-making processes which incorporate two basic principles of finance: the maximization of shareholders' wealth and that the value of the company depends on investor expectations that the future profits will exceed the cost of the capital. EVA is directly related to the external performance of the company in the capital market, i.e. Market Value Added - MVA. MVA is the assessment of the capital markets, within a specified period of time and reflects the success with which the company invested capital in the past and expectations of the success of performance of investing capital in the future, which affects the value of the company, and thus a shareholder value, as well.

    Accurate height-resolved measurements of higher-order statistical moments of vertical velocity fluctuations are crucial for improved understanding of turbulent mixing and diffusion, convective initiation, and cloud life cycles. The Atmospheric Radiation Measurement (ARM) Climate Research Facility operates coherent Doppler lidar systems at several sites around the globe. These instruments provide measurements of clear-air vertical velocity profiles in the lower troposphere with a nominal temporal resolution of 1 sec and height resolution of 30 m. The purpose of the Doppler lidar vertical velocity statistics (DLWSTATS) value-added product (VAP) is to produce height- and time-resolved estimates of vertical velocity variance, skewness, and kurtosis from these raw measurements. The VAP also produces estimates of cloud properties, including cloud-base height (CBH), cloud frequency, cloud-base vertical velocity, and cloud-base updraft fraction.

    Standard Atmospheric Radiation Measurement (ARM) Climate Research Facility sounding files provide atmospheric state data in one dimension of increasing time and height per sonde launch. Many applications require a quick estimate of the atmospheric state at higher time resolution. The INTERPOLATEDSONDE (i.e., Interpolated Sounding) Value-Added Product (VAP) transforms sounding data into continuous daily files on a fixed time-height grid, at 1-minute time resolution, on 332 levels, from the surface up to a limit of approximately 40 km. The grid extends that high so the full height of soundings can be captured; however, most soundings terminate at an altitude between 25 and 30 km, above which no data is provided. Between soundings, the VAP linearly interpolates atmospheric state variables in time for each height level. In addition, INTERPOLATEDSONDE provides relative humidity scaled to microwave radiometer (MWR) observations.

It is a twin data product of the ARMBE 2-Dimensional gridded (ARMBE2DGRID) data set. Unlike the ARMBE2DGRID data set, ARMBESTNS data are reported at the original site locations and show the original information (except for the interpolation over time). Therefore, the users have the flexibility to process the data with the approach more suitable for their applications. This document provides information about the input data, quality control (QC) method, and output format of this data set. As much of the information is identical to that of the ARMBE2DGRID data, this document will emphasize more on the different aspects of these two data sets.

    2012-01-09

    The Sonde Adjust (SONDEADJUST) value-added product (VAP) creates a file that includes all fields from original Atmospheric Radiation Measurement Climate Research Facility (ARM Facility) radiosonde files and contains several value-added fields that provide adjustments related to well-known humidity issues. SONDEADJUST produces data that correct documented biases in radiosonde humidity measurements. Previous efforts towards applying some of these corrections are available via the discontinued PI product sgpsondecorr1miloC1. Unique fields contained within this datastream include smoothed original relative humidity, dry bias corrected relative humidity, and final corrected relative humidity. The smoothed RH field refines the relative humidity from integers-the resolution of the instrument-to fractions of a percent. This profile is then used to calculate the dry bias corrected field. The final correction fixes the time-lag problem and uses the dry-bias field as input into the algorithm. In addition to dry bias, solar heating is another correction that is encompassed in the final corrected RH field. Output from SONDEADJUST differs from the previous RH-corrected datastreams in important ways. First, all three types of ARM radiosondes-Vaisala RS-80, RS-90, and RS-92-are corrected using dedicated procedures and/or parameters. Second, the output variables include all of those found in the original radiosonde file: dry bulb temperature, dewpoint temperature, wind speed, wind direction, eastward wind component, northward wind component, wind status (a Vaisala-produced field used in conjunction with the Loran system), ascent rate, and original relative humidity. Additional humidity fields are smoothed relative humidity, dry biased corrected relative humidity, final ambient relative humidity, and scaled adjusted relative humidity. Third, quality control (QC) flags of the fields from the original radiosonde datastream are brought into the SONDEADJUST output file. Additional QC

    2014-01-01

    In the past few years, the number of studies regarding the application of ionic liquids (ILs) as alternative solvents to extract value-added compounds from biomass has been growing. Based on an extended compilation and analysis of the data hitherto reported, the main objective of this review is to provide an overview on the use of ILs and their mixtures with molecular solvents for the extraction of value-added compounds present in natural sources. The ILs (or IL solutions) investigated as solvents for the extraction of natural compounds, such as alkaloids, flavonoids, terpenoids, lipids, among others, are outlined. The extraction techniques employed, namely solid–liquid extraction, and microwave-assisted and ultrasound-assisted extractions, are emphasized and discussed in terms of extraction yields and purification factors. Furthermore, the evaluation of the IL chemical structure and the optimization of the process conditions (IL concentration, temperature, biomass–solvent ratio, etc.) are critically addressed. Major conclusions on the role of the ILs towards the extraction mechanisms and improved extraction yields are additionally provided. The isolation and recovery procedures of the value-added compounds are ascertained as well as some scattered strategies already reported for the IL solvent recovery and reusability. Finally, a critical analysis on the economic impact versus the extraction performance of IL-based methodologies was also carried out and is here presented and discussed. PMID:25516718

    Full Text Available The production of biofuels worldwide has been significant lately due to the shift from obtaining energy from nonrenewable energy (fossil fuels to renewable sources (biofuels. This energy shift arose as a result of the disturbing crude petroleum price fluctuations, uncertainties about fossil fuel reserves, and greenhouse gas (GHG concerns. With the production of biofuels increasing considerably and the current global biodiesel production from different feedstock, reaching about 6 billion liters per year, biodiesel production costs have been highly dependent on feedstock prices, ranging from 70 to 25; of total production costs, and in comparison with the conventional diesel fuel, the biodiesel is currently noncompetitive. An efficient production process is, therefore, crucial to lowering biodiesel production costs. The question of sustainability, however, arises, taking into account the African diverse conditions and how vital concerns need to be addressed. The major concern about biodiesel production costs can be reduced by finding value-added applications for its glycerol byproduct. This paper, thus, provides an overview of current research trends that could overcome the major hurdles towards profitable commercialization of biodiesel and also proposes areas of opportunity probable to capitalize the surplus glycerol obtained, for numerous applications.

    Standard Atmospheric Radiation Measurement (ARM) Climate Research Facility sounding files provide atmospheric state data in one dimension of increasing time and height per sonde launch. Many applications require a quick estimate of the atmospheric state at higher time resolution. The INTERPOLATEDSONDE (i.e., Interpolated Sounding) Value-Added Product (VAP) transforms sounding data into continuous daily files on a fixed time-height grid, at 1-minute time resolution, on 332 levels, from the surface up to a limit of approximately 40 km. The grid extends that high so the full height of soundings can be captured; however, most soundings terminate at an altitude between 25 and 30 km, above which no data is provided. Between soundings, the VAP linearly interpolates atmospheric state variables in time for each height level. In addition, INTERPOLATEDSONDE provides relative humidity scaled to microwave radiometer (MWR) observations.The INTERPOLATEDSONDE VAP, a continuous time-height grid of relative humidity-corrected sounding data, is intended to provide input to higher-order products, such as the Merged Soundings (MERGESONDE; Troyan 2012) VAP, which extends INTERPOLATEDSONDE by incorporating model data. The INTERPOLATEDSONDE VAP also is used to correct gaseous attenuation of radar reflectivity in products such as the KAZRCOR VAP.

    2015-12-25

    As a major primary producer in marine environments, diatoms have been considered as promising feedstocks for their applications in functional foods, bioactive pharmaceuticals, and cosmetics. This review focuses on the biotechnology potential of diatoms for value-added products like carotenoids. The impact of abiotic environmental stresses, such as intensity and quality of incident light, nutrient deficiency and silicon depletion, on diatoms has been examined to determine key factors that affect the growth performance and the accumulation of valuable compounds. Previous studies suggested that adaptive evolution could be an efficient method to improve the diatom productivity of valuable compounds. Light emitting diode (LED)-based photobioreactors were introduced and proposed as a promising new technology for producing quality products from diatoms. Currently available molecular biology tools were also summarized and discussed in relation to their application in the production of carotenoids and other valuable products. Taken together, systems biology and synthetic biology approaches have the potential to address the challenges faced while working toward the industrial application of diatoms.

    2013-09-01

    Full Text Available Biodiesel has gained a significant amount of attention over the past decade as an environmentally friendly fuel that is capable of being utilized by a conventional diesel engine. However, the biodiesel production process generates glycerol-containing waste streams which have become a disposal issue for biodiesel plants and generated a surplus of glycerol. A value-added opportunity is needed in order to compensate for disposal-associated costs. Microbial conversions from glycerol to valuable chemicals performed by various bacteria, yeast, fungi, and microalgae are discussed in this review paper, as well as the possibility of extending these conversions to microbial electrochemical technologies.

    The Iowa Corn Promotion Board is the principal contracting entity for this grant funded by the US Department of Agriculture and managed by the US Department of Energy. The Iowa Corn Promotion Board subcontracted with New Jersey Institute of Technology, KiwiChem, Pacific Northwest National Lab and Idaho National Lab to conduct research for this project. KiwiChem conducted the economic engineering assessment of a dry-mill ethanol plant. New Jersey Institute of Technology conducted work on incorporating the organic acids into polymers. Pacific Northwest National Lab conducted work in hydrolysis of hemicellulose, fermentation and chemical catalysis of sugars to value-added chemicals. Idaho National Lab engineered an organism to ferment a specific organic acid. Dyadic, an enzme company, was a collaborator which provided in-kind support for the project. The Iowa Corn Promotion Board collaborated with the Ohio Corn Marketing Board and the Minnesota Corn Merchandising Council in providing cost share for the project. The purpose of this diverse collaboration was to integrate the hydrolysis, the conversion and the polymer applications into one project and increase the likelihood of success. This project had two primary goals: (1) to hydrolyze the hemicellulose fraction of the distillers grain (DG) coproduct coming from the dry-mill ethanol plants and (2) convert the sugars derived from the hemicellulose into value-added co-products via fermentation and chemical catalysis.

  2. Multi-Angle Snowflake Camera Value-Added Product

    The Multi-Angle Snowflake Camera (MASC) addresses a need for high-resolution multi-angle imaging of hydrometeors in freefall with simultaneous measurement of fallspeed. As illustrated in Figure 1, the MASC consists of three cameras, separated by 36°, each pointing at an identical focal point approximately 10 cm away. Located immediately above each camera, a light aims directly at the center of depth of field for its corresponding camera. The focal point at which the cameras are aimed lies within a ring through which hydrometeors fall. The ring houses a system of near-infrared emitter-detector pairs, arranged in two arrays separated vertically by 32 mm. When hydrometeors pass through the lower array, they simultaneously trigger all cameras and lights. Fallspeed is calculated from the time it takes to traverse the distance between the upper and lower triggering arrays. The trigger electronics filter out ambient light fluctuations associated with varying sunlight and shadows. The microprocessor onboard the MASC controls the camera system and communicates with the personal computer (PC). The image data is sent via FireWire 800 line, and fallspeed (and camera control) is sent via a Universal Serial Bus (USB) line that relies on RS232-over-USB serial conversion. See Table 1 for specific details on the MASC located at the Oliktok Point Mobile Facility on the North Slope of Alaska. The value-added product (VAP) detailed in this documentation analyzes the raw data (Section 2.0) using Python: images rely on OpenCV image processing library and derived aggregated statistics rely on some clever averaging. See Sections 4.1 and 4.2 for more details on what variables are computed.

    Bio-electrochemical systems (BESs) are the microbial systems which are employed to produce electricity directly from organic wastes along with some valuable chemicals production such as medium chain fatty acids; acetate, butyrate and alcohols. In this review, recent updates about value-added chemicals production concomitantly with the production of gaseous fuels like hydrogen and methane which are considered as cleaner for the environment have been addressed. Additionally, the bottlenecks associated with the conversion rates, lower yields and other aspects have been mentioned. In spite of its infant stage development, this would be the future trend of energy, biochemicals and electricity production in greener and cleaner pathway with the win-win situation of organic waste remediation. Henceforth, this review intends to summarise and foster the progress made in the BESs and discusses its challenges and outlook on future research advances. Copyright © 2017 Elsevier Ltd.

    The European Bioinformatics Institute (EMBL-EBI) provides public access to patent data, including abstracts, chemical compounds and sequences. Sequences can appear multiple times due to the filing of the same invention with multiple patent offices, or the use of the same sequence by different inventors in different contexts. Information relating to the source invention may be incomplete, and biological information available in patent documents elsewhere may not be reflected in the annotation of the sequence. Search and analysis of these data have become increasingly challenging for both the scientific and intellectual-property communities. Here, we report a collection of non-redundant patent sequence databases, which cover the EMBL-Bank nucleotides patent class and the patent protein databases and contain value-added annotations from patent documents. The databases were created at two levels by the use of sequence MD5 checksums. Sequences within a level-1 cluster are 100% identical over their whole length. Level-2 clusters were defined by sub-grouping level-1 clusters based on patent family information. Value-added annotations, such as publication number corrections, earliest publication dates and feature collations, significantly enhance the quality of the data, allowing for better tracking and cross-referencing. The databases are available format: http://www.ebi.ac.uk/patentdata/nr/. PMID:19884134

  8. Engineered soy oils for new value added applications

    Science.gov (United States)

    Tran, Phuong T.

    Soybean oil is an abundant annually renewable resource. It is composed of triglycerides with long chain saturated and unsaturated fatty acids. The presence of unsaturated fatty acids allows for chemical modification to introduce new functionalities to soybean oil. A portfolio of chemically modified soy oil with suitable functional groups has been designed and engineered to serve as the starting material in applications such as polyamides, polyesters, polyurethanes, composites, and lubricants. Anhydride, hydroxyl, and silicone functionalities were introduced to soy oil. Anhydride functionality was introduced using a single-step free radical initiated process, and the chemically modified soy oils were evaluated for potential applications as a composite and lubricant. Hydroxyl functionalities were introduced in a single-step catalytic ozonolysis process recently developed in our labs, which proceeds rapidly and efficiently at room temperature without solvent. The transformed soy oil was used to successfully prepare bio-lubricants with good thermal/oxidative stability and bio-plastics such as polyamides, polyesters, and polyurethanes. A new class of organic-inorganic hybrid materials was prepared by curing vinyltrimethoxysilane functionalized soy oil. This hybrid material could have potential as biobased sealant through a moisture initiated room temperature cure. These new classes of soy-based materials are competitive both in cost and performance to petroleum based materials, but offer the advantage of being biobased.

    Full Text Available One of the major issues in the future Internet is the integration of telecom networks with the Internet. In many countries, large Internet Service Providers (ISPs are also telecom operators that have been focusing on providing Internet services through their telecom networks with telecom-grade mechanisms. In this article, we show that IP Multimedia Subsystem (IMS is a telecom-grade mechanism that addresses this important issue. In Next Generation Network (NGN, IMS supports IP-based multimedia services that can be accessed from various wireless and wired access technologies through fixed-mobile convergence. We show how to integrate Internet Protocol Television (IPTV with NGN/IMS to offer enhanced IPTV services for subscribers with set-top boxes or mobile phones. We specifically describe the implementations of three services: weather forecasts, short messages on TV screens and TV shopping/food ordering for mobile users. Although these services can be directly implemented in the Internet, our commercial operation experiences indicate that the NGN/IMS implementation has advantages in terms of telecom-grade security, Quality of Service (QoS, and flexible service creation.

  11. Targeting post-ejaculation sperm for value-added contraception.

    The spermatogenesis is a precisely-timed cellular proliferation that takes place in the seminiferous tubules of testes and is meticulously regulated by gonadotrophins, androgens and temperature. Hormonal, nonhormonal and thermal methods of male contraception have been researched with success; though a clinically viable method is yet to evolve. Testicular sperm lack motility and fertilizing ability, which they gain during their transit through the long epididymal conduit whose distal end serves as a store house of mature sperm in a quiescent state, ready for ejaculation during coitus. Epididymal maturation has been a target for male contraceptive research to avert interruptions of fundamental testicular functions like spermatogenesis and steroidogenesis. However, several experimental successes have not yet yielded a practicable method of fertility regulation. Coitus culminates in the propulsion of epididymal sperm within seconds through the vas deferens into the female vagina and marks the initiation of sperm motility, a vigorous physical activity that is crucial for fertilization. Highly motile spermatozoa have a brief stay in the vagina before starting their ascent in the female reproductive tract. Vaginal spermatozoa have been targeted for contraception since ages. Spermicides and sperm immobilizers inactivate sperm immediately on deposition in the vagina, while they are placed in a rather 'ex-vivo' condition outside the body. Their need based usage, minimal systemic involvement; easy application, self-controlled reversibility and potential capability to obliterate sexually transmitted infections add significant value to contraception. We have reviewed here our recent endeavors in this important area of chemical contraception by using designed chemical synthesis approach to inhibit spermatozoa and infection.

    Full Text Available Global supply chains have changed the way in which products are produced internationally. The inputs into a final product include both intermediate goods and services, which adds value to the final product. Gross trade data is misleading and includes some double counting. This study questions whether traditional revealed comparative advantage (RCA calculations for gross exports of services would offer different results from value-added services. RCA calculation was done for South Africa and the bric countries for both gross exports and value added services. The analysis showed that some countries performed stronger in terms of gross exports than in value added terms for some sectors, but others showed higher comparative advantage in value added terms. For South Africa, most services had a higher comparative advantage in terms of value added than for gross exports. The results indicated the importance of including value added data in international trade data analysis.

  14. Value-added products from chicken feather fiber and protein

    Science.gov (United States)

    Fan, Xiuling

    Worldwide poultry consumption has generated a huge amount of feather "waste" annually. Currently, the feather has a low value-being used for animal feed in the world. The quality of fibrous air filters depend on their main component, fibers. The main physical structure of chicken feathers is barbs which can be used directly as fibers. They have small diameter, which makes them a good choice for air filtration. The main chemical structure of chicken feathers is structural fibrous protein, keratin. Therefore, chicken feathers could potentially be used for protein fiber production. To obtain chicken feather fibers, barbs were stripped from the quills by a stripping device and separated with a blender. Some feather fibers were entangled with polyester staple fibers, and needlepunched to form a nonwoven fabric. Some feather fibers were blended with CelBond(TM) bi-component polyester as binder fibers, and pressed between two hot plates to produce thermobonded nonwovens. Whole chicken feathers were ground into powder and their keratin was reduced in water. The reduced keratin was salt precipitated, dried and dissolved in ionic liquid with/without bleach cotton. The reduced chicken feather keratin ionic liquid solutions were spun into regenerated fibers through dry-jet wet spinning. The needlepunched and thermobonded nonwovens were tested for filtration and other properties. With an increase of areal density and feather fiber composition, the air permeability of the needlepunched nonwovens decreased, and their filtration efficiency and pressure drop both increased. The case can be made that feather fibers gave fabrics better filtration at the same fabric weight, but at the expense of air permeability and pressure drop. The scrim and needlepunching process improved the filtration efficiency. Their strength depended on scrim. The hot-press process was very simple. The thermobonded nonwovens had very high air permeability. In them, there was also an inverse relation between

  15. The economic impact of reduced value added tax rates for groceries

    Slavomíra Martinková

    2016-12-01

    Full Text Available The value added tax represents one of the most important sources of state budget revenues of EU Member States. The basic value added tax rate is in the EU currently between 15% in Luxembourg to 27% applied in Hungary. The revenues from this tax represent an average of 17.5% of all tax revenues of EU countries and create an average GDP of 7.0% (year 2016, EU 28. As revenues from value added tax represent a stable income of state budget, the legislative changes in the system of value added tax, mainly its reductions as well as its imposition on groceries, can significantly influence further macroeconomic development. In the last year, the government of the Slovak Republic implemented changes in universal indirect taxing in such way that in addition to the standard value added tax rate of 20%, the Act No. 268/2015 on Value added tax adopted in 2016 a decreased value added tax rate of 10% on selected groceries, in order to support domestic producers and reduce the tax burden of low-income and middle-income groups. According to the European Commission (2007, the reduced rate of value added tax in selected cases has its justification and importance in the country's economy. The aim of this paper is to analyse the economic impact of the applied reduced value added tax on food in the Slovak Republic in the context of household expenditures and revenues of the state budget.

  1. Value-added materials from the hydrometallurgical processing of jarosite waste

    Directory of Open Access Journals (Sweden)

    Wilson Benjamin P.

    2016-01-01

    Full Text Available Jarosite is a leach residue that can be produced by industrial bulk metal treatment processes and typically has the chemical formula MxFe3(SO42(OH6, where M normally represents a metal cation. The largest source of jarosite is electrolytic zinc processing [1], which worldwide has an annual production of 11-12 Mt and an associated jarosite waste of 5-6 Mt that can cause important challenges due to its classification as a problem waste. Moreover, as zinc ore typically contains many other commercial/critical metals, the content of valuable materials in this material is significant. An analysis of jarosite from Kokkola, Finland shows that it contained as much metal as many present day commercial ores: ~15% iron, 2% zinc, 3 % lead, 150 g/t silver, 0.5 g/t gold, 100 g/t indium and 40 g/t gallium. Until now, jarosite related research has concentrated on its use in landfill and construction purposes [2], though there is increasing interest in finding methods to efficiently reprocess/recycle jarosite into valuable products [3, 4]. The hydrometallurgical process currently under development by VTT and Aalto University exploits jarosite powdery nature to undertake wet chemical processing. This low cost and energy efficient operation is targeted at the recovery of concentrates which contain the major value-added metals.

    Bilal, Muhammad; Asgher, Muhammad; Iqbal, Hafiz M N; Hu, Hongbo; Zhang, Xuehong

    2017-05-01

    In the past decade, with the key biotechnological advancements, lignocellulosic materials have gained a particular importance. In serious consideration of global economic, environmental and energy issues, research scientists have been re-directing their interests in (re)-valorizing naturally occurring lignocellulosic-based materials. In this context, lignin-modifying enzymes (LMEs) have gained considerable attention in numerous industrial and biotechnological processes. However, their lower catalytic efficiencies and operational stabilities limit their practical and multipurpose applications in various sectors. Therefore, to expand the range of natural industrial biocatalysts e.g. LMEs, significant progress related to the enzyme biotechnology has appeared. Owing to the abundant lignocellulose availability along with LMEs in combination with the scientific advances in the biotechnological era, solid-phase biocatalysts can be economically tailored on a large scale. This review article outlines first briefly on the lignocellulose materials as a potential source for biotransformation into value-added products including composites, fine chemicals, nutraceutical, delignification, and enzymes. Comprehensive information is also given on the purification and characterization of LMEs to present their potential for the industrial and biotechnological sector. Copyright © 2017 Elsevier B.V.

    Directory of Open Access Journals (Sweden)

    Nufazil Altaf

    2016-12-01

    Full Text Available The purpose of this paper is to empirically test the claim made by Stern Stewart & Company that economic value added is a better metric that traditional earning based measures in explaining market value. For better exposition, a sample of 325 Indian firms has been divided into two parts- 170 firms belonging to Indian manufacturing companies and 155 companies belonging to the Indian service sector. After performing univariate and multivariate regression analyses, the results of the study reveal that the operating income has a strong linkage with market value added in both manufacturing and service sectors. For both the sectors, the economic value added shows weaker but positive relationship with the market value added.

The analysis of the value added is made on the example of bakeries in Orenburg region. A new concept of «quality value» is presented and indicators for its evaluation are developed. Quality is understood as value-added content and structure of the value added nature of its formation, modification and distribution between the main actors in the value chain of the product under the influence of various factors. The conducted research confirmed the hypothesis that the implementation of a larger number of activities to create the final product in a controlled set of economic agents improves their performance. It is established that the structure of the value depends not only on the performance of individual enterprises, but also on the industry in general.

    Nature of the Event: Technology demonstration. The project successfully met all of its technical objectives. Albacem has signed an exclusive licensing agreement with Vitro Minerals Inc., a specialty minerals company, to commercialize the Albacem technology (website: www.vitrominerals.com). Location: The basic research for the project was conducted in Peoria, Illinois, and Atlanta, Georgia, with third-party laboratory verification carried out in Ontario, Canada. Pilot-scale trials (multi-ton) were conducted at a facility in South Carolina. Full-scale manufacturing facilities have been designed and are scheduled for construction by Vitro Minerals during 2006 at a location in the Georgia, North Carolina, and South Carolina tri-state area. The Technology: This technology consists of a process to eliminate solid wastes generated at glass fiber manufacturing facilities by converting them to value-added materials (VCAS Pozzolans) suitable for use in cement and concrete applications. This technology will help divert up to 250,000 tpy of discarded glass fiber manufacturing wastes into beneficial use applications in the concrete construction industry. This technology can also be used for processing glass fiber waste materials reclaimed from monofills at manufacturing facilities. The addition of take-back materials and reclamation from landfills can help supply over 500,000 tpy of glass fiber waste for processing into value added products. In the Albacem process, waste glass fiber is ground to a fine powder that effectively functions as a reactive pozzolanic admixture for use in portland ce¬ment-based building materials and products, such as concrete, mortars, terrazzo, tile, and grouts. Because the waste fiber from the glass manufacturing industry is vitreous, clean, and low in iron and alkalis, the resulting pozzolan is white in color and highly consistent in chemical composition. This white pozzolan, termed VCAS Pozzolan (for Vitreous Calcium-Alumino-Silicate). is

    The economic value added is formed under the influence of two major factors: the difference between the economic profitability and the weighted average cost of capital, called the rate of economic value generation and the value of the economic asset exploited by the company. To stimulate the process of creation of economic value added, the company must act in the sense of increasing the rate of economic value generation and development of the volume of the economic asset.

    2016-09-01

    Full Text Available The aim of the paper is to propose a model for measuring sustainable value which would complexly assess environmental, social, and corporate governance contribution to value creation. In the paper the concept of the Sustainable Environmental, Social and Corporate Governance Value Added is presented. The Sustainable Environmental, Social and Corporate Governance Value Added is based on the Sustainable Value Added model and combines weighted environmental, social, and corporate governance indicators with their benchmarks determined by Data Envelopment Analysis. Benchmark values of indicators were set for each company separately and determine the optimal combination of environmental, social, and corporate governance inputs to economic outcomes. The Sustainable Environmental, Social and Corporate Governance Value Added methodology is applied on real-life corporate data and presented through a case study. The value added of most of the selected companies was negative, even though economic indicators of all of them are positive. The Sustainable Environmental, Social and Corporate Governance Value Added is intended to help owners, investors, and other stakeholders in their decision-making and sustainability assessment. The use of environmental, social, and corporate governance factors helps identify the company’s strengths and weaknesses, and provides a more sophisticated insight into it than the one-dimensional methods based on economic performance alone.

  16. Impact of catalysis on the production of the top 50 US commodity chemicals

    1994-03-01

    Information on each chemical is stored in an accompanying Excel{trademark} 4.0 spreadsheet (``top5Ochem.xcl``). This analysis tool allows the user to make assumptions about process yield improvements and evaluate the corresponding impact on the process and feedstock energy. Many scenarios have been investigated and are reported in the text. If all of the catalytic processes associated with the top 50 chemicals were raised to their maximum process yields, the corresponding process and feedstock energy savings would exceed 0.47 quads per year. More realistic process yield improvements of 1%, 5%, and 10% where possible, would save 0.03, 0.14, and 0.23 quads per year. Many of the commodity chemicals face limitations from both the current catalyst and process. Catalysis is vital, but catalysis alone is not the answer to maximizing energy savings. Integration of catalysis development with process engineering research can lead to significant energy savings during the production of the top 50 chemicals.

    Cost allocation at manufacturing industry particularly in Palm Oil Mill still widely practiced based on estimation. It leads to cost distortion. Besides, processing time determined by company is not in accordance with actual processing time in work station. Hence, the purpose of this study is to eliminates non-value-added activities therefore processing time could be shortened and production cost could be reduced. Activity Based Costing Method is used in this research to calculate production cost with Value Added and Non-Value-Added Activities consideration. The result of this study is processing time decreasing for 35.75% at Weighting Bridge Station, 29.77% at Sorting Station, 5.05% at Loading Ramp Station, and 0.79% at Sterilizer Station. Cost of Manufactured for Crude Palm Oil are IDR 5.236,81/kg calculated by Traditional Method, IDR 4.583,37/kg calculated by Activity Based Costing Method before implementation of Activity Improvement and IDR 4.581,71/kg after implementation of Activity Improvement Meanwhile Cost of Manufactured for Palm Kernel are IDR 2.159,50/kg calculated by Traditional Method, IDR 4.584,63/kg calculated by Activity Based Costing Method before implementation of Activity Improvement and IDR 4.582,97/kg after implementation of Activity Improvement.

    Cheap fossil oil resources are becoming depleted and crude oil prices are rising. In this context, alternatives to fossil fuel-derived carbon are examined in an effort to improve the security of carbon resources through the development of novel technologies for the production of chemicals, fuels, and materials from renewable feedstocks such as biomass. The general concept unifying the conversion processes for raw biomass is that of the biorefinery, which integrates biofuels with a selection of pivot points towards value-added chemical end products via so-called "platform chemicals". While the concept of biorefining is not new, now more than ever there is the motivation to investigate its true potential for the production of carbon-based products. A variety of renewable chemicals have been proposed by many research groups, many of them being categorized as drop-ins, while others are novel chemicals with the potential to displace petrochemicals across several markets. To be competitive with petrochemicals, carbohydrate-derived products should have advantageous chemical properties that can be profitably exploited, and/or their production should offer cost-effective benefits. The production of drop-ins will likely proceed in short term since the markets are familiar, while the commercial introduction of novel chemicals takes longer and demands more technological and marketing effort.Rather than describing elaborate catalytic routes and giving exhaustive lists of reactions, a large part of this review is devoted to creating a guideline for the selection of the most promising (platform) chemicals derived via chemical-catalytic reaction routes from lignocellulosic biomass. The major rationale behind our recommendations is a maximum conservation of functionality, alongside a high atom economy. Nature provides us with complex molecules like cellulose and hemicellulose, and it should be possible to transform them into chemical products while maintaining aspects of their

    Full Text Available Non-value-adding activities are pure waste during the construction process. However, most of the construction practitioner does not realise that most of the activities performed during the construction process add no value to their project. A total of 375 numbers of questionnaires distributed to the Developer, Jabatan Kerja Raya, Consultants and Contractors. The study found that awareness by construction participants in Malaysia to take actions against non-value-adding activities during the construction process is relatively low. Through analysed by using the Pareto Chart, it has been found that defects and waiting time are two categories of non-value-adding activities that need to be prioritised by the industry. It is also found that non-value-adding activities most frequently occurred during structural and architectural work. This paper also reviewed on the causes of non-value-adding activities and discussed its effect towards time, cost, quality and productivity of the construction project. This paper is also important to give clearness and broader understandings on this form of waste other than material waste.

    2015-03-01

    Health care is in a state of transition, shifting from volume-based success to value-based success. Hospital executives and referring physicians often do not understand the total value a radiology group provides. A template for easy, cost-effective implementation in clinical practice for most radiology groups to demonstrate the value they provide to their clients (patients, physicians, health care executives) has not been well described. A value management program was developed to document all of the value-added activities performed by on-site radiologists, quantify them in terms of time spent on each activity (investment), and present the benefits to internal and external stakeholders (outcomes). The radiology value-added matrix is the platform from which value-added activities are categorized and synthesized into a template for defining investments and outcomes. The value management program was first implemented systemwide in 2013. Across all serviced locations, 9,931.75 hours were invested. An annual executive summary report template demonstrating outcomes is given to clients. The mean and median individual value-added hours per radiologist were 134.52 and 113.33, respectively. If this program were extrapolated to the entire field of radiology, approximately 30,000 radiologists, this would have resulted in 10,641,161 uncompensated value-added hours documented in 2013, with an estimated economic value of $2.21 billion.

    Full Text Available Value Added Tax (VAT is a tax imposed on the value added to a product at each stage of the production and distribution process. Value added is never taxed twice under VAT and thus cascading (tax on tax effects do not occur. It is a single tax on goods and services but the tax is collected multiple stages. At each of these stages, the amount of tax payable is computed by subtracting the tax previously paid on purchases from the tax charged on sales by the traders for each taxation period. In last three decades, VAT, a relatively new and better commodity taxation, has been introduced in many countries. It has replaced different types of sales taxes in such countries. This article attempts to evaluate VAT by comparing with other sales taxes.

    Full Text Available Tax policy represents one of the EU integration policies. The aim of the tax policy is to remove the national differences in taxation systems by withdrawing the obstacles to the competition and free movement of goods, services, people and capital on the internal market. Tax harmonization has the greatest development in the area of value added taxation, but differences still can be found. Those differences influence not only the farming business. The paper is aimed on five EU member states – Czech Republic, Poland, Rumania, Slovak Republic and Hungary. Based on the EU regulations in the area of value added tax and the practical experience during its application, it is possible to identify the critical areas and to contribute to its correction and to provide the value added tax neutrality and efficiency on the EU territory.

    Jan Klasinc

    2015-12-01

    Full Text Available Purpose - The hypothesis of the paper is that domestic value added created by exports in Croatia could be increased by investments in green economy. Methodology - In the developed economies only specific products, processes and functions that outperform emerging economies in Global Value Chains are able to profit from the larger share of value added. Large portion of "green economy" is knowledge intensive, and if knowledge based economy (KBC plays a significant role in determining the domestic value added created by exports, economies with a larger stock of KBC should have a larger difference in VAX between knowledge-intensive industries and less knowledge-intensive industries. Domestic value added embodied in exports can be proxied by attracted FDI. Findings - The results seem to show some support to the hypothesis. In Croatia it has already been shown that sectors of economy with larger stock of intellectual capital measured by Intellectual Capital Efficiency (ICE index attracted more FDI, which can also serve as a predictor for larger value added in exports due to higher productivity. Knowledge intensity of 18 industries in the US as the benchmark economy shows that "Electrical and optical equipment" has above average knowledge intensity of 0,53, and it can be matched with "green economy" in Croatian industries that attracted more FDI and have higher levels of KBC. Research limitations and implications - Although this study is limited just to KBC, as an extension, the potential role of financial development could be included. Also, the length of time series for VAX measured by OECD does not allow for more thorough analysis. Originality/value – Although not conclusive, this paper is an important first step giving direction to subsequent studies of effects of KBC on value added.

    Methane and methanol are potential carbon sources of industrial micro-organisms in addition to crop-derived bio-carbon sources. Methanotrophs that can utilize these simple, stable and large amounts chemicals are expected to be developed into 'cell factories' for the production of specific chemicals. In this study, a methanotroph that can synthesize lycopene, C 30 carotenoid and exopolysaccharides (EPS) with relative better performances from C1 substrates was isolated, and its performances were evaluated. The isolated strain was identified as Methylomonas sp. ZR1 based on 16S rRNA sequence analysis. Its maximum specific growth rate achieved 0·200 h -1 under flask culture conditions, and 0·386 h -1 in bubble column reactors. ZR1 was able to utilize 35 g l -1 of methanol and even exhibited slight growth in the presence of 40 g l -1 of methanol. Furthermore, ZR1 was proved to synthesize lycopene (C 40 carotenoids) besides the C 30 carotenoids through HPLC-DAD and HPLC-MS/MS analysis methods. Its carotenoid extracts exhibited excellent antioxidative activities measured by the ABTS + method. Plenty of polysaccharides were also synthesized by ZR1, the components of the polysaccharides were identified as glucose, mannose and galactose with a proportion of 1 : 2 : 1 by GC-MS, and its yield achieved 0·13 g g -1 cell dry weight. The isolated strain has great potential for the production of value-added bioproducts from C1 compounds because of its excellent C1 substrate utilizing abilities and its abilities to naturally synthesize lycopene, C 30 carotenoids and EPS. In this study, we isolated a fast-growing methanotroph, its C1 carbon substrate utilizing ability is excellent in comparison with reported methanotrophs. Furthermore, besides polysaccharides and C 30 carotenoids which were commonly synthesized by methanotrophs, our findings suggested that C 40 lycopene could also be naturally synthesized from methane by methanotrophs. © 2017 The Society for Applied

    Full Text Available Nowadays electronic taxation is being one of the important issues for revenue administrations. Tax administrations try to organize their tax system fairly and give attention on equity. Value added tax is most preferable taxes among the consumption taxes. Because it’s application is easy and taxpayers don’t show resistance to the value added tax. On electronic commerce value added taxes are using commonly. To provide equity in taxation, some taxation principles are adapted for value added taxes too. In this paper, we are trying to analyze the development of e-commerce in the world and e-taxation regulations and problems in the European Union (EU and Organization for Economic Cooperation and Development (OECD countries. The EU and OECD countries are making regulations in this issue. The last regulation is Base Erosion and Profit Shifting 15 point action plan in 2014. Taxation of the digital economy is the first action plan. In addition this, some regulations about taxation of digital economy are being done in Turkey in the case of Base Erosion and Profit Shifting action plan.

    Full Text Available his study poses to investigate the impact of entries of social nature as overlooked by traditional accounting when compiling expanded value added figures, before value added accounting. To this effect, an exploratory qualitative survey was conducted at a non-profit organization located in the State of Santa Catarina, Brazil. The study´s object was Indaial´s Women's Network Against Cancer (SC, an association of social and philanthropic purpose, deemed of both municipal and state public interest. Study results indicate that the value added statement -compiled as of financial information gathered at the researched institution– presents both employees and the government as being the prime beneficiaries of the wealth therein generated. Once both acknowledgement and measurement of volunteer service derived social entries are incorporated, compiled value added figures raise 82.92%. This disclosure approach extends the scope of beneficiaries of generated wealth beyond that of employees and government to include the organization itself - which receives social care program preparation and management services - and society as a whole, the ultimate addressee of services deployed by non-profit entities. One may come to the conclusion that social accounting concepts enable the understanding of both social and economic dynamics of this kind of organization.

    By aggregating residual gain scores (the differences between each student's current score and a predicted score based on prior performance) for a school or a teacher, value-added models (VAMs) can be used to generate estimates of school or teacher effects. It is known that random errors in the prior scores will introduce bias into predictions of…

  11. The top 50 commodity chemicals: Impact of catalytic process limitations on energy, environment, and economics

    Energy Technology Data Exchange (ETDEWEB)

    Tonkovich, A.L.Y.; Gerber, M.A.

    1995-08-01

    The production processes for the top 50 U.S. commodity chemicals waste energy, generate unwanted byproducts, and require more than a stoichiometric amount of feedstocks. Pacific Northwest Laboratory has quantified this impact on energy, environment, and economics for the catalytically produced commodity chemicals. An excess of 0.83 quads of energy per year in combined process and feedstock energy is required. The major component, approximately 54%, results from low per-pass yields and the subsequent separation and recycle of unreacted feedstocks. Furthermore, the production processes, either directly or through downstream waste treatment steps, release more than 20 billion pounds of carbon dioxide per year to the environment. The cost of the wasted feedstock exceeds 2 billion dollars per year. Process limitations resulting from unselective catalysis and unfavorable reaction thermodynamic constraints are the major contributors to this waste. Advanced process concepts that address these problems in an integrated manner are needed to improve process efficiency, which would reduce energy and raw material consumption, and the generation of unwanted byproducts. Many commodity chemicals are used to produce large volume polymer products. Of the energy and feedstock wasted during the production of the commodity chemicals, nearly one-third and one-half, respectively, represents chemicals used as polymer precursors. Approximately 38% of the carbon dioxide emissions are generated producing polymer feedstocks.

  12. PREVENTION OF FRAUD IN THE AREA OF VALUE ADDED TAX WITHIN THE EUROPEAN UNION

    Directory of Open Access Journals (Sweden)

    2016-12-01

    Full Text Available Frauds that occur in the area of value added tax damage not only financial interests of the state, but also the financial interests of the European Union. The phenomenon of fraud in the scope of the value added tax system appeared in 1993 upon the abolition of customs controls. Due to the application of the cross-border taxation system for transactions within the European Union based on the destination principle, tax frauds occur in transactions in goods, and later in connection with transactions in services, as well. The paper deals with reasons for the occurrence of these types of frauds, with markets that are subject to illegal activity and with an analysis of possible solutions for their prevention. Since certain prevention solutions are already in use, the paper analyses their effectiveness and presents the possibility of their combination.

  13. Value added medicines: what value repurposed medicines might bring to society?

    Science.gov (United States)

    Toumi, Mondher; Rémuzat, Cécile

    2017-01-01

    Background & objectives : Despite the wide interest surrounding drug repurposing, no common terminology has been yet agreed for these products and their full potential value is not always recognised and rewarded, creating a disincentive for further development. The objectives of the present study were to assess from a wide perspective which value drug repurposing might bring to society, but also to identify key obstacles for adoption of these medicines and to discuss policy recommendations. Methods : A preliminary comprehensive search was conducted to assess how the concept of drug repurposing was described in the literature. Following completion of the literature review, a primary research was conducted to get perspective of various stakeholders across EU member states on drug repurposing ( healthcare professionals, regulatory authorities and Health Technology Assessment (HTA) bodies/payers, patients, and representatives of the pharmaceutical industry developing medicines in this field). Ad hoc literature review was performed to illustrate, when appropriate, statements of the various stakeholders. Results : Various nomenclatures have been used to describe the concept of drug repurposing in the literature, with more or less broad definitions either based on outcomes, processes, or being a mix of both. In this context, Medicines for Europe (http://www.medicinesforeurope.com/value-added-medicines/) established one single terminology for these medicines, known as value added medicines, defined as 'medicines based on known molecules that address healthcare needs and deliver relevant improvements for patients, healthcare professionals and/or payers'. Stakeholder interviews highlighted three main potential benefits for value added medicines: (1) to address a number of medicine-related healthcare inefficiencies related to irrational use of medicines, non-availability of appropriate treatment options, shortage of mature products, geographical inequity in medicine access

  14. Value added tax evasion and excise duty fraud on fuel market in the Czech Republic

    Directory of Open Access Journals (Sweden)

    Pavel Semerád

    2012-01-01

    Full Text Available This paper deals with analysis of current problems in the motor fuel market. It analyzes bottlenecks in setting the legislative changes in value added tax, excise tax and the legislation concerning fuels. The biggest problem is tax evasions that favor one group of business entities at the expense of another, and also cause that the state loses revenues mainly from indirect taxes. Therefore, attention is directed to quality control of fuels as a means of consumer protection and prevention of tax evasion and ways to combat tax evasion in import, distribution and storage of mineral oils. The examples are the most common errors found in fraudulent companies. Based on the data collected the possible ultimate evasion was estimated. Therefore, I propose that value added tax law should be amended and some other measures to improve supervision by public authorities like tax authorities and customs administration offices should be taken.

    Recent advances in lipopolysaccharide (LPS) biology have led to its use in drug discovery pipelines, including vaccine and vaccine adjuvant discovery. Desirable characteristics for LPS vaccine candidates include both the ability to produce a specific antibody titer in patients and a minimal host inflammatory response directed by the innate immune system. However, in-depth chemical characterization of most LPS extracts has not been performed; hence, biological activities of these extracts are unpredictable. Additionally, the most widely adopted workflow for LPS structure elucidation includes nonspecific chemical decomposition steps before analyses, making structures inferred and not necessarily biologically relevant. In this work, several different mass spectrometry workflows that have not been previously explored were employed to show proof-of-principle for top down LPS primary structure elucidation, specifically for a rough-type mutant (J5) E. coli-derived LPS component of a vaccine candidate. First, ion mobility filtered precursor ions were subjected to collision induced dissociation (CID) to define differences in native J5 LPS v. chemically detoxified J5 LPS (dLPS). Next, ultra-high mass resolving power, accurate mass spectrometry was employed for unequivocal precursor and product ion empirical formulae generation. Finally, MS3 analyses in an ion trap instrument showed that previous knowledge about dissociation of LPS components can be used to reconstruct and sequence LPS in a top down fashion. A structural rationale is also explained for differential inflammatory dose-response curves, in vitro, when HEK-Blue hTLR4 cells were administered increasing concentrations of native J5 LPS v. dLPS, which will be useful in future drug discovery efforts.

    2011-06-01

    Full Text Available Economic value added (EVA is an indicator which is widely used as the main tool for financial analysis. There are two methods of calculating it. The original method which was made by Stern & Stewart is defined as the net operating profit after taxes minus the cost of capital. The second method which was developed and used by the “Czech Ministry of Industry and Trade” indicates that, the economic value added is the difference between return on equity and the alternate cost of equity that is composed of separate risk rewards, and this “spread” is consequently multiplied by the equity. Economic value added depends on many factors. Whereas some of them are controllable by the company, others are not. This article is focused on the relationship between economic value added and the corporate- vs. market life cycle. This is because, there is an assumption that conditions for developing EVA changes depending on the actual phase of corporate- and market life cycle. In this research, the model by Reiners (2004 is used to identify the phases of corporate- and market life cycle and the method provided by the “Czech Ministry of Industry and Trade” is used to calculate EVA. However, there is a consideration of the relativity of EVA in the form of “spread” because of the intercompany comparison. The study found that, the highest spread is achieved by companies that are in the phase of expansion and phase of market expansion. On the contrary, companies in the phase of declension during market declension achieved the lowest and negative spread.

    We have developed a simple, scalable, transfer-free, ecologically sustainable, value-added method to convert inexpensive coal tar pitch to patterned graphene films directly on device substrates. The method, which does not require an additional transfer process, enables direct growth of graphene films on device substrates in large area. To demonstrate the practical applications of the graphene films, we used the patterned graphene grown on a dielectric substrate directly as electrodes of bottom-contact pentacene field-effect transistors (max. field effect mobility ~0.36 cm2·V-1·s-1), without using any physical transfer process. This use of a chemical waste product as a solid carbon source instead of commonly used explosive hydrocarbon gas sources for graphene synthesis has the dual benefits of converting the waste to a valuable product, and reducing pollution.

    Full Text Available Background: Whole slide imaging (WSI makes it possible to capture images of an entire histological slide. WSI has established roles in surgical pathology, including support of off-site frozen section interpretation, primary diagnosis, educational activities, and laboratory quality assurance (QA activities. Analyses of the cost of WSI have traditionally been based solely on direct costs and diagnostic accuracy; however, these types of analyses largely ignore workflow and cost issues that arise as a result of redundancy, the need for additional staffing, and customized software development when WSI is integrated into routine diagnostic surgical pathology. The pre-scan, scan, and post-scan costs; quality control and QA costs; and IT process costs can be significant, and consequently, pathology groups can find it difficult to perform a realistic cost-benefit analysis of adding WSI to their practice. Materials and Methods: In this paper, we report a "value added" approach developed to guide our decisions regarding integration of WSI into surgical pathology practice. The approach focuses on specific operational measures (cost, time, and enhanced patient care and practice settings (clinical, education, and research to identify routine activities in which the addition of WSI can provide improvements. Results: When applied to our academic pathology group practice, the value added approach resulted in expanded and improved operations, as demonstrated by outcome based measures. Conclusion: A value added can be used to perform a realistic cost-benefit analysis of integrating WSI into routine surgical pathology practice.

    Since Europe is considering to establish a "market-driven" European Global Navigation Satellite System, the German Center of Aerospace initiated a market research to justify a German investment in such a European project. The market research performed included the following market segments: aviation, railway, road traffic, shipping, surveying, farming, military, space applications, leisure, and sport. In these market segments, the forementioned inputs were determined for satellite navigation hardware (receivers) as well as satellite navigation services. The forecast period was from year 2007 to 2017. For the considered period, the market amounts to a total of DM 83.0 billion (approx. US $50 billion), whereas the satellite navigation equipment market makes up DM 39.8 billion, and charges for value-added-services amount to DM 43.2 billion. On closer examination road traffic can be identified as the dominant market share, both in the receiver-market and service-market. With a share of 96% for receivers and 73% for services the significance of the road traffic segment becomes obvious. The second part of this paper investigates the effects the market potential has on the Value-Adding-Chain. Therefore, all participants in the Value-Adding-Chain are identified, using industrial cost structure models the employment effect is analyzed, and possible tax revenues for the state are examined.

    2015-12-01

    Recently, various solid wastes such as sewage sludge, coal fly ash and slag have been recycled into various products such as sintered bricks, ceramics and cement concrete. Application of these recycling approaches is much better and greener than conventional landfills since it can solve the problems of storage of industrial wastes and reduce exploration of natural resources for construction materials to protect the environment. Therefore, in this study, an attempt was made to recycle oil shale fly ash (OSFA), a by-product obtained from the extracting of shale oil in the oil shale industry, into a value-added glass-ceramic material via melting and sintering method. The influence of basicity (CaO/SiO2 ratio) by adding calcium oxide on the performance of glass-ceramics was studied in terms of phase transformation, mechanical properties, chemical resistances and heavy metals leaching tests. Crystallization kinetics results showed that the increase of basicity reduced the activation energies of crystallization but did not change the crystallization mechanism. When increasing the basicity from 0.2 to 0.5, the densification of sintering body was enhanced due to the promotion of viscous flow of glass powders, and therefore the compression strength and bending strength of glass-ceramics were increased. Heavy metals leaching results indicated that the produced OSFA-based glass-ceramics could be taken as non-hazardous materials. The maximum mechanical properties of compression strength of 186 ± 3 MPa, bending strength of 78 ± 6 MPa, good chemical resistances and low heavy metals leaching concentrations showed that it could be used as a substitute material for construction applications. The proposed approach will be one of the potential sustainable solutions in reducing the storage of oil shale fly ash as well as converting it into a value-added product.

    2002-05-01

    Carps are the mainstay of Indian aquaculture, contributing over 90% to the total fish production, which was estimated to be 1.77 million metric tonnes in 1996. Carp culture has a great potential for waste utilization and thus for pollution abatement. Many wastes such as cow, poultry, pig, duck, goat, and sheep excreta, biogas slurry, effluents from different kinds of factories/industries have been efficiently used for enhancing the productivity of natural food of carps and related species. Besides, several organic wastes/byproducts such as plant products, wastes from animal husbandry, and industrial by-products have been used as carp feed ingredients to lower the cost of supplementary feeding. However, to ensure the continued expansion of fish ponds and the pollution control, there must be a market for the fish (carps) produced in these ponds. The carps have, however, a low market value due to the presence of intra-muscular bones, which reduces their consumer acceptability. Thus, a need was felt to develop some boneless convenience products for enhancing the consumer acceptability of the carps. Efforts were made to prepare three value-added fish products, namely fish patty, fish finger and fish salad from carp flesh and were compared with a reference product ('fish pakoura'). Sensory evaluation of these products gave highly encouraging results. The methods of preparation of these products were transferred to some progressive farmers of the region who prepared and sold these products at very attractive prices. Carp processing has a great potential for the establishment of a fish ancillary industry and thus for boosting the production of these species. In Punjab alone, there is a potential of consuming 32,448 metric tonnes per annum of such value-added products (which would require 54,080 metric tonnes of raw fish). The development of value-added products has a significant role in raising the socio-economic status of the people associated with carp culture. The

    Employers clamour for more "Highly-Qualified Personnel" (HQP) to hire, and photonics is no exception. The challenge facing all new graduates lies in what actually constitutes a Highly-Qualified Person. Yesterday, an HQP was often understood to be a graduate with a Bachelor's, Master's or Ph.D. degree. Today, industry is demanding that an HQP be either a university or college graduate with strong academic standing AND a sound business and communications skill set. In this paper, we introduce the concept of "Value-Added Personnel" (VAP), which marries both scientific and "soft-skills" aspects, and we present a new program in Ontario to produce VAPs.

From the results of the analysis, we concluded that, the highest efficiency ratio (50.8 was recorded in Croatia in 2013. This indicates that Croatia’s value-added tax revenues as percentage of gross domestic product in the state budget were very high (12.7 in comparison to Turkey’s (9.0 in 2013. As such, VAT is one of the most important taxes in the EU-28 Member States and many countries worldwide, like Turkey. The current VAT system in EU-28 Member States and Turkey is quite complex for the growing number of businesses operating cross-border. To increase investment, competitiveness and growth, an action plan on VAT is proposed for the creation of a single VAT area. The VAT system needs to be more efficient and simpler for businesses to use.

  11. Value-Added Products from FGD Sulfite-Rich Scrubber Materials

    2010-01-31

    According to the American Coal Ash Association, about 29.25 million tons of flue gas desulfurization (FGD) byproducts were produced in the USA in 2003. Out of 29.25 million tons, 17.35 million tons were sulfite-rich scrubber materials. At present, unlike its cousin FGD gypsum, the prospect for effective utilization of sulfite-rich scrubber materials is not bright. In fact, almost 16.9 million tons are leftover every year. In our pursuit to mitigate the liability of sulfite-rich FGD scrubber materials' disposal, we are attempting to develop value-added products that can commercially compete. More specifically, for this Innovative Concept Phase I project, we have the following objectives: to characterize the sulfite-rich scrubber material for toxic metals; to optimize the co-blending and processing of scrubber material and natural byproducts; to formulate and develop structural composites from sulfite-rich scrubber material; and to evaluate the composites' mechanical properties and compare them with current products on the market. After successfully demonstrating the viability of our research, a more comprehensive approach will be proposed to take these value-added materials to fruition.

    In an era of competition in health care delivery, those who pay for care are interested in supporting primarily those activities that add value to the clinical enterprise. The authors report on their 1998 project to develop a conceptual model for assessing the value added to clinical care by educational activities. Through interviews, nine key stakeholders in patient care identified five ways in which education might add value to clinical care: education can foster higher-quality care, improve work satisfaction of clinicians, have trainees provide direct clinical services, improve recruitment and retention of clinicians, and contribute to the future of health care. With this as a base, an expert panel of 13 clinical educators and investigators defined six perspectives from which the value of education in clinical care might be studied: the perspectives of health-care-oriented organizations, clinician-teachers, patients, education organizations, learners, and the community. The panel adapted an existing model to create the "Education Compass" to portray education's effects on clinical care, and developed a new set of definitions and research questions for each of the four major aspects of the model (clinical, functional, satisfaction, and cost). Working groups next drafted proposals to address empirically those questions, which were critiqued at a national conference on the topic of education's value in clinical care. The next step is to use the methods developed in this project to empirically assess the value added by educational activities to clinical care.

  13. Integrating information from decentralized laboratory testing sites. The creation of a value-added network.

    The decentralization of laboratory testing provides distinct advantages for clinicians and patients, such as the reduction of test turnaround time, but also promotes the development of scattered caches of results. This problem could be ameliorated by the creation of an integrated laboratory data base. Such an approach would provide clinicians with a patient view of laboratory information in addition to the functional view of it that is offered currently. Impressive technologic advances are being made in the development of a distributed computer architecture in which processing tasks and information are shared across multiple hardware platforms attached to a network. Such architecture could be used to create a regional value-added laboratory network to integrate test information generated in decentralized testing sites. Independent reference laboratories and tertiary-care referral hospitals are the most likely candidates to create distributed value-added networks. Pathologists should view themselves as health-care professionals responsible for the processing, storage, and transmission of information, as well as for its generation. In time, the partition of information along hospital geopolitical boundaries will appear archaic and will be replaced by an emphasis on local and regional integration of medical information similar to that advocated here.

  14. Value Added Elements According to Buyer Companies in a B2B Context

    2015-07-01

    Full Text Available This paper analyses how buyer companies perceive the value added to products and services offered by their suppliers and identifies the predominant elements that affect purchasing decisions and establishment of relationships between companies in a B2B context. A multiple case study was developed in 12 buyer companies from three industrial segments in southern Brazil: metal-mechanics, furniture and foods. The findings show that for supplier companies in the metal-mechanics industry to add value, they must identify buyers’ needs, develop technology/innovation, be focused on competitive aspects, keep control of the supply chain, provide different purchasing channels, develop partnerships, and adapt to cultural aspects. Companies in the food industry consider the model for creating value to adapt to meet customer needs, the effective use of purchasing channels, functionality of products, and technical knowledge. The companies in the furniture industry value the methods that suppliers use to capture and implement required changes, effective control of the supply chain, and the representativeness of the suppliers’ brand in the market. This study captures the perception of buyer companies in relation to predominant value-adding elements and could guide decisions for the adoption of managerial actions by supplier companies focused on adding value.

    Full Text Available This study aimed at investigating the impact of value-added tax on corporate financial performance of quoted companies. To achieve this purpose, we developed some hypotheses and critically reviewed existing theoretical and empirical literatures. Agribusinesses quoted in the Nigerian Stock Exchange Factbook of 2009 were considered as the population for this study. The population elements include the General Managers, Chief Accountants, Finance Managers, Chief Internal Auditors, External Auditors, and Tax Administrators of the selected companies. A total of forty (42 respondents were considered for this study. A well structured questionnaire designed in five-point Likert Scale was administered on the respondents to elicit their responses. The data generated for this study were presented in tabular form and analyzed using frequencies and simple percentages while the stated hypotheses were statistically tested with the simple regression analysis and the t-test. Our findings indicated that Value-Added Tax (VAT impacted negatively on the financial performance of agribusinesses though the impact is of insignificant value. Based on our findings, we recommended that agribusinesses should endeavour to keep appropriate source documents of all transactions for efficient VAT operations and that the governments should ensure that proper tax incentive scheme is designed and fully implemented to promote the growth of agribusinesses, in Nigeria.

    Full Text Available This article analyzes the definitions of the main taxable events for the Value-Added Tax (VAT based on a comparative approach to thelegislation of different countries (Spain, Mexico, Chile, Colombia, Argentina and Peru. In this regard, it analyzes which legislations offer definitions according to the principles of generality, fiscal neutrality and legal certainty for VAT. Moreover, it points out that the VAT systems of those countries do not require as a condition for the configuration of the taxable events that the transactions involve a «value added» or a final consumption. In the specificcase of «supplies of goods», the VAT systems have a similar definition of the taxable event, although there are a few differences. However, in the case of«supplies of services», which is the most important taxable event for VAT, there are important differences at the time each country defines it. This is not a desirable effect for the international trade of services, since the lack of harmonization produces double taxation or double non taxation.

    Full Text Available Contemporary trade analysis indicates the necessity of calculating trade in value added (TiVA which is created through global value chains (GVCs. This paper aims to determine the characteristics and importance of GVC trade in the EU new member states (EU NMS with special emphasis placed on the industry level. The results demonstrate different levels of GVC participation of the EU NMS, where Hungary is the most integrated country and Croatia the least integrated. Regional GVCs exist because a huge part of value added (VA comes from EU member states, as in gross export as well as in final demand (Europe as a hub. The most important source countries are Germany and Italy and there is also evidence of geographical and historical relations between the countries. The domination of backward participation has been found in the analysis made on the industrial level, i.e. the EU NMS are highly dependent on the import of intermediates for the production and export of final products. Strong interconnections between imports of intermediate products and exports of final products have been found in the manufacture of computers, electronics and optical products; manufacture of wood, paper, printing and reproduction. This research has contributed to the scarce literature concerning GVC (TiVA in EU NMS and has opened up new possibilities for further research and analysis.

    Full Text Available This paper examines the changing patterns of transnational value chains in the Asia-Pacific region. The methodology is based on the analysis of data extracted from the OECD – WTO Trade in Value Added Database (2016. The study demonstrates that 1 Asia-Pacific countries show extremely high involvement in the global value chains; 2 intra-Asian value chains develop at a fast pace, reflecting the trend towards regiona-lization of economic ties in Asia-Pacific (caused by the processes of transformation within China, the growing income divergence in the region and the development of regional integration mechanisms; 3 the level of participation in global value chains differs across countries and is subject to constant changes. In particular, Chinese manufacturers are moving to the processes with higher value added, and the role of an ‘assembly shop’ in the region is shifting to the ASEAN countries. Russia’s participation in the value chains in the Asia-Pacific region is currently limited to its role as a supplier of raw materials. High tariffs make manufacturing oriented towards Asia less viable, especially considering that most of Asia-Pacific countries have free trade agreements with each other. However, favorable rules of origin in Asian RTAs as well as good political relations with leading Asian countries in conditions of tensions between them still create some opportunities for involving Russia in regional value chains at the more advanced stages

    Full Text Available The relationship IRS taxpayer runs the risk of turning into a psychological war in which, however, given the positions held, the IRS is by far on a favorable footing. Between the apparently excessively formal position held by the IRS, which seems to conceal behind the laws, and the sometimes forced interpretation of the laws, by the taxpayer, there are the courts of law, also disturbed by the legislative changes which appear to have entered a perpetual motion. The objective of the fiscal administration regarding the value added tax is to combat tax evasion and fraud. It is very important to combat evasion in the VAT field because it represents the indirect tax of the largest share in the consolidated general budget. VAT evasion represents the intention of not paying the tax, withholding or not declaring it, or requesting its refund which would not be fit, due to the exaggeration of the deductible amount of the VAT. The essential aim of the IRS inspector is to verify the correctness of the declared amount of the value added tax. It should also be observed whether the incorrectness is deliberate or whether it was due to misunderstanding, carelessness or the ignorance of the payer. In all cases judgment is necessary, as for the cases of negligence the amount to be paid must be corrected and accompanied by applying fines and / or penalties, and in the cases of intended fraud legal actions are to be applied in order to obtain a conviction. Deceitful deductions represent other methods for tax evasion and are undertaken based on fake invoices, invoices often used several times for deduction, or invoices related to purchases that have never been made. Thus there are examples of economic agents who have practiced the right to deduct the VAT due to the acquisition of goods which consisted in the property of other economic agents. In other cases noticed was the deduction of VAT on goods or services that were not included in the activities of the economic

    A strain designated as BA03, with the ability to transform ferulic acid into vanillin and 4-vinylguaiacol, was isolated from contaminated cryovials. The production of natural value-added compounds was dependent on the media employed. The morphological and physiological characteristics of this strain were compared with those of the typical vanillin-producer strain Amycolatopsis sp. ATCC 39116. According to a partial 16S rRNA sequence, we determined that BA03 belonged to Bacillus aryabhattai. In addition, analysis of the results showed that this strain exhibited interesting enzymatic activity, including cellulases, laccases, lipases and pectinases. In light of this, we propose new functions for this multitasking microorganism. We suggest that it may be used for converting lignocellulosic wastes into byproducts with industrial uses, and also for treating disposal residues such as dyes in the textile industry. Hence, the possibility for novel research with B. aryabhattai opens up in the fields of biodegradation and/or revalorization of wastes.

    2011-07-15

    This document describes the input requirements, output data products, and methodology for the Spectral Surface Albedo (SURFSPECALB) value-added product (VAP). The SURFSPECALB VAP produces a best-estimate near-continuous high spectral resolution albedo data product using measurements from multifilter radiometers (MFRs). The VAP first identifies best estimates for the MFR downwelling and upwelling shortwave irradiance values, and then calculates narrowband spectral albedo from these best-estimate irradiance values. The methodology for finding the best-estimate values is based on a simple process of screening suspect data and backfilling screened and missing data with estimated values when possible. The resulting best-estimate MFR narrowband spectral albedos are used to determine a daily surface type (snow, 100% vegetation, partial vegetation, or 0% vegetation). For non-snow surfaces, a piecewise continuous function is used to estimate a high spectral resolution albedo at 1 min temporal and 10 cm-1 spectral resolution.

  2. Improved Correction of IR Loss in Diffuse Shortwave Measurements: An ARM Value-Added Product

    2003-11-01

    Simple single black detector pyranometers, such as the Eppley Precision Spectral Pyranometer (PSP) used by the Atmospheric Radiation Measurement (ARM) Program, are known to lose energy via infrared (IR) emission to the sky. This is especially a problem when making clear-sky diffuse shortwave (SW) measurements, which are inherently of low magnitude and suffer the greatest IR loss. Dutton et al. (2001) proposed a technique using information from collocated pyrgeometers to help compensate for this IR loss. The technique uses an empirically derived relationship between the pyrgeometer detector data (and alternatively the detector data plus the difference between the pyrgeometer case and dome temperatures) and the nighttime pyranometer IR loss data. This relationship is then used to apply a correction to the diffuse SW data during daylight hours. We developed an ARM value-added product (VAP) called the SW DIFF CORR 1DUTT VAP to apply the Dutton et al. correction technique to ARM PSP diffuse SW measurements.

    The disposal of fly ash from coal-fired power stations causes significant economic and environmental problems. A relatively small percentage of the material finds application as an ingredient in cement and other construction products, but the vast majority of material generated each year is held in ash dams or similar dumps. This unproductive use of land and the associated long-term financial burden of maintenance has led to realization that alternative uses for fly ash as a value-added product beyond incorporation in construction materials are needed. Utilization of fly ash in such areas as novel materials, waste management, recovery of metals and agriculture is reviewed in this article with the aim of looking at new areas that will expand the positive reuse of fly ash, thereby helping to reduce the environmental and economic impacts of disposal

    The KAZRCOR Value -added Product (VAP) performs several corrections to the ingested KAZR moments and also creates a significant detection mask for each radar mode. The VAP computes gaseous attenuation as a function of time and radial distance from the radar antenna, based on ambient meteorological observations, and corrects observed reflectivities for that effect. KAZRCOR also dealiases mean Doppler velocities to correct velocities whose magnitudes exceed the radar’s Nyquist velocity. Input KAZR data fields are passed through into the KAZRCOR output files, in their native time and range coordinates. Complementary corrected reflectivity and velocity fields are provided, along with a mask of significant detections and a number of data quality flags. This report covers the KAZRCOR VAP as applied to the original KAZR radars and the upgraded KAZR2 radars. Currently there are two separate code bases for the different radar versions, but once KAZR and KAZR2 data formats are harmonized, only a single code base will be required.

    4-Hydroxybenzoic acid (4-HBA) has recently emerged as a promising intermediate for several value-added bioproducts with potential biotechnological applications in food, cosmetics, pharmacy, fungicides, etc. Over the past years, a variety of biosynthetic techniques have been developed for producing the 4-HBA and 4-HBA-based products. At this juncture, synthetic biology and metabolic engineering approaches enabled the biosynthesis of 4-HBA to address the increasing demand for high-value bioproducts. This review summarizes the biosynthesis of a variety of industrially pertinent compounds such as resveratrol, muconic acid, gastrodin, xiamenmycin, and vanillyl alcohol using 4-HBA as the starting feedstock. Moreover, potential research activities with a close-up look at the future perspectives to produce new compounds using 4-HBA have also been discussed.

    The aip1ogren value-added product (VAP) computes several aerosol intensive properties. It requires as input calibrated, corrected, aerosol extensive properties (scattering and absorption coefficients, primarily) from the Aerosol Observing Station (AOS). Aerosol extensive properties depend on both the nature of the aerosol and the amount of the aerosol. We compute several properties as relationships between the various extensive properties. These intensive properties are independent of aerosol amount and instead relate to intrinsic properties of the aerosol itself. Along with the original extensive properties we report aerosol single-scattering albedo, hemispheric backscatter fraction, asymmetry parameter, and Ångström exponent for scattering and absorption with one-minute averaging. An hourly averaged file is produced from the 1-minute files that includes all extensive and intensive properties as well as submicron scattering and submicron absorption fractions. Finally, in both the minutely and hourly files the aerosol radiative forcing efficiency is provided.

    Full Text Available Consideration represents one of the cumulatively prescribed conditions for the taxation of supplies of goods in value added tax system. In the absence of consideration there is in general no basis for taxation, which makes room for untaxed final consumption - the case in which a taxpayer deducts input VAT on purchased good that is subsequently used for his own or another person's final consumption free of charge. In this paper, the author analyzes the situations in which, for taxation purposes, the supplies of goods free of charge will be treated equally as supplies for consideration and, relying on the jurisprudence of the European Court of Justice, notes the deviations of the domestic practice from the communautaire one, while providing concrete recommendations for their elimination.

It is often stated that the competitive added value has the particular way in which the employees are motivated and also their skills within the organization. The authors believe that the added value in a competitive market is the result of the synergy of the two types of motivations, the entrepreneurial and managerial ones and employee's own motivation. In situations where a synergy between the interests of workers and the organization's ones, the global interests of the company's is characterized by continuous growth of value added, while lack of motivation generates unequivocally conflicting states that diminishes the aspects of the outcome activities quality.

    Controlled fermentation of Sweet potato ( Ipomoea batatas ) var. Beauregard by yeast, Saccharomyces boulardii (MAY 796) to enhance the nutritional value of sweet potato was investigated. An average 8.00 × 10 10 Colony Forming Units (CFU)/g of viable cells were obtained over 5-day high-solid fermentation. Yeast cell viability did not change significantly over time at 4°C whereas the number of viable yeast cells reduced significantly at room temperature (25°C), which was approximately 40% in 12 months. Overall, the controlled fermentation of sweet potato by MAY 796 enhanced protein, crude fiber, neutral detergent fiber, acid detergent fiber, amino acid, and fatty acid levels. Development of value-added sweet potato has a great potential in animal feed and human nutrition. S. boulardii - fermented sweet potato has great potential as probiotic-enriched animal feed and/or functional food for human nutrition.

    2017-12-01

    This review aims to present an innovative concept of high value added lipids produced by heterotrophic microorganisms, bacteria and fungi, using carbon sources, such as sugars, acids and alcohols that could come from sugarcane vinasse, which is the main byproduct from ethanol production that is released in the distillation step. Vinasse is a rich carbon source and low-cost feedstock produced in large amounts from ethanol production. In 2019, the Brazilian Ministry of Agriculture, Livestock and Food Supply estimates that growth of ethanol domestic consumption will be 58.8 billion liters, more than double the amount in 2008. This represents the annual production of more than 588 billion liters of vinasse, which is currently used as a fertilizer in the sugarcane crop, due to its high concentration of minerals, mainly potassium. However, studies indicate some disadvantages such as the generation of Greenhouse Gas emission during vinasse distribution in the crop, as well as the possibility of contaminating the groundwater and soil. Therefore, the development of programs for sustainable use of vinasse is a priority. One profitable alternative is the fermentation of vinasse, followed by an anaerobic digester, in order to obtain biomaterials such as lipids, other byproducts, and methane. Promising high value added lipids, for instance carotenoids and polyunsaturated fatty acids (PUFAS), with a predicted market of millions of US$, could be produced using vinasse as carbon source, to guide an innovative concept for sustainable production. Example of lipids obtained from the fermentation of compounds present in vinasse are vitamin D, which comes from yeast sucrose fermentation and Omega 3, which can be obtained by bacteria and fungi fermentation. Additionally, several other compounds present in vinasse can be used for this purpose, including sucrose, ethanol, lactate, pyruvate, acetate and other carbon sources. Finally, this paper illustrates the potential market and

In fact, at present, the production of wet sulfite-rich scrubber cake outstrips the production of wet sulfate-rich scrubber cake by about 6 million tons per year. However, most of the utilization focus has centered on FGD gypsum. Therefore, we have recently initiated research on developing new strategies for the economical, but environmentally-sound, utilization of sulfite-rich scrubber material. In this exploratory project (Phase I), we attempted to ascertain whether it is feasible to develop reconstituted wood replacement products from sulfite-rich scrubber material. In pursuit of this goal, we characterized two different wet sulfite-rich scrubber materials, obtained from two power plants burning Midwestern coal, for their suitability for the development of value-added products. The overall strategy adopted was to fabricate composites where the largest ingredient was scrubber material with additional crop materials as additives. Our results suggested that it may be feasible to develop composites with flexural strength as high as 40 MPa (5800 psi) without the addition of external polymers. We also attempted to develop load-bearing composites from scrubber material, natural fibers, and phenolic polymer. The polymer-to-solid ratio was limited to {le} 0.4. The formulated composites showed flexural strengths as high as 73 MPa (10,585 psi). We plan to harness the research outcomes from Phase I to develop parameters required to upscale our value-added products in Phase II.

    Full Text Available This research investigated the simultaneous impact and partial impact of financial ratios (ROA, ROE, EPS and Economic Value-Added (EVA on stock return. One of the four independent variables, that is EVA, are new concepts for measuring financial performance. Explanatory method was used in this research, and the sample was collected using purposive sampling method from Jakarta Islamic Index listed in Bursa Efek Indonesia (BEI, Indonesia Stock Exchange for the period 2005 - 2007. Multiple linear regression was used for the analysis in this research.The result of the analysis shows that all independent variables, that is Return on Assets (ROA, Return on Equity (ROE, Earnings per Share (EPS and EVA have both simultaneous and partial impact on the dependent variable, that is stock return. An interesting finding is that the regression coefficients are different among the variables. ROE and EPS were found to have positive and significant impact on dependent variable while EVA and ROA were found to have negative and significant impact on dependent variable. A positive value for ROE means that the ROE variable can be taken as a measure for a company’s effectivity in utilizing equity in the effort to gain profit. While EPS was found to have the most dominant impact on stock price. The higher the EPS, the greater management’s success in gaining profit for the shareholder or investors. ROA was found to have negative and significant. A finding of this research which is contrary to previous research is that economic value added (EVA was found to have negative and significant impact on stock price. However this finding can be explained as follows: first, the average debt in the companies in the sample is greater than the value of their equity so that EVA will increase due to the reduction in WACC. The increase in EVA is accompanied by a reduction in stock return. Second, positive EVA is not accompanied by any increase of stock performance in the market; and

    Full Text Available Reverse charge mechanism is considered to be a specific mechanism when applying the value added tax. The liability to declare and pay the output tax is transferred to the recipient of the fulfillment within the reverse charge mechanism. Since Apri1 1, 2011 there has been extended the application of the reverse charge mechanism to the domestic (home fulfillments and since this date the mechanism has been applied to the delivery of slag, waste and metal scrap, defined in the Annex 5 and to the trading with the greenhouse gas emissions allowances. Since January 1, 2012 the reverse charge mechanism has been applied also for construction and assembly works which leads to a significant extension of VAT payers which this provision may affect. The paper will evaluate the impacts of the application of the reverse charge mechanism to the provider and the recipient of the taxable fulfillments, mainly for the construction works. There will be evaluated also the impacts of the administrative burden related to the evidence of the reverse charge mechanism for the tax entity and also for the tax administrator.

  2. A Method for Proposing Valued-Adding Attributes in Customized Housing

    Full Text Available In most emerging economies, there has been many incentives and high availability of funding for low-cost housing projects. This has encouraged product standardization and the application of mass production ideas, based on the assumption that this is the most effective strategy for reducing costs. However, the delivery of highly standardized housing units to customers with different needs, without considering their lifestyle and perception of value, often results in inadequate products. Mass customization has been pointed out as an effective strategy to improve value generation in low-cost housing projects, and to avoid waste caused by renovations done in dwellings soon after occupancy. However, one of the main challenges for the implementation of mass customization is the definition of a set of relevant options based on users’ perceived value. The aim of this paper is to propose a method for defining value adding attributes in customized housing projects, which can support decision-making in product development. The means-end chain theory was used as theoretical framework to connect product attributes and costumers’ values, through the application of the laddering technique. The method was tested in two house-building projects delivered by a company from Brazil. The main contribution of this method is to indicate the customization units that are most important for users along with the explanation of why those units are the most relevant ones.

    Grapes are one of the most cultivated fruits worldwide, with one third of total production used in winemaking. Both red and white winemaking processes result in substantial quantities of solid organic waste, such as grape marc (pomace) and stalks, which requires suitable disposal. Grape marc accounts for approximately 10-30% of the mass of grapes crushed and contains unfermented sugars, alcohol, polyphenols, tannins, pigments, and other valuable products. Being a natural plant product rich in lignocellulosic compounds, grape marc is also a promising feedstock for renewable energy production. However, despite grape marc having such potential, advanced technologies to exploit this have not been widely adopted in wineries and allied industries. This review covers opportunities beyond traditional composting and animal feed, and examines value-added uses via the extraction of useful components from grape marc, as well as thermochemical and biological treatments for energy recovery, fuel or beverage alcohol production, and specialty novel products and applications such as biosurfactants and environmental remediation. New advances in relevant technology for each of these processes are discussed, and future directions proposed at both individual producer and regional facility scales, including advanced processing techniques for integrated ethanol production followed by bioenergy generation from the spent marc.

    The environmental impacts of palm oil mill effluent (POME) have been a concern due to the water pollution and greenhouse gases emissions. Thus, this study was conducted to recover the value-added products from POME source before being discharged. The samples, before (X) and after (Y) the pre-recovery system in the clarification tank were sampled and analysed and proximate analysis indicated that both samples are energy rich source of food due to high contents of fats and carbohydrates. GCMS analysis showed that the oil extracts contain predominantly palmitic, oleic, linoleic and stearic acids. Regiospecific analysis of oil extracts by quantitative 13 C-NMR spectroscopy demonstrated that both oil extracts contain similar degree of saturation of fatty acids at sn-2 and sn-1,3 positions. The samples are rich in various phytonutrients, pro-vitamin A, vitamin E, squalene and phytosterols, thus contributing to exceptionally high total flavonoid contents and moderate antioxidant activities. Overall, samples X and Y are good alternative food sources, besides reducing the environmental impact of POME.

  6. Smart value-added fiber-optic modules using spatially multiplexed processing

    Riza, Nabeel A.; Azer Reza, Syed

    2007-06-01

    Intelligent fiber-optic value-added modules (VAMs) are proposed using what we believe to be a novel spatially multiplexed processing technique implemented with both reconfigurable and nonreconfigurable predesigned pixels per impinging beam that enables desired optical power split states needed for realizing a two state reconfigurable VAM. The preferred design uses broadband micromirrors such as ones fabricated via optical microelectromechanical systems technology. The basic VAM design uses two broadband micromirror pixels, where each pixel has its specific location and area and only one of these pixels is electrically driven to adjust its small tilt angle. The areas of the pixels are chosen to obtain the desired tap power. A proof-of-concept VAM with 100% digital repeatability is demonstrated using a Texas Instruments Digital Micromirror Device (DMD) where several micromirrors per beam are used to produce the dual-pixel effect. Example tap ratios experimentally implemented at 1550 nm include 10:90, 20:80, 66.66:33.33, 50:50, 30:70, and 25:75. DMD multipixel diffraction limits output port optical losses to 3.2 and 3.6 dB. The proposed VAM can have an impact in both digital electronic and analog RF optically implemented systems.

  7. Value Added Tax and price stability in Nigeria: A partial equilibrium analysis

    2013-12-01

    Full Text Available The economic impact of Value Added Tax (VAT that was implemented in Nigeria in 1994 has generated much debate in recent times, especially with respect to its effect on the level of aggregate prices. This study empirically examines the influence of VAT on price stability in Nigeria using partial equilibrium analysis. We introduced the VAT variable in the framework of a combination of structuralist, monetarist and fiscalist approaches to inflation modelling. The analysis was carried out by applying multiple regression analysis in static form to data for the 1994-2010 period. The results reveal that VAT exerts a strong upward pressure on price levels, most likely due to the burden of VAT on intermediate outputs. The study rules out the option of VAT exemptions for intermediate outputs as a solution, due to the difficulty in distinguishing between intermediate and final outputs. Instead, it recommends a detailed post-VAT cost-benefit analysis to assess the social desirability of VAT policy in Nigeria.

    A recently initiated program of British Columbia Hydro, called 'building check-up' (BCU), which provides a package of value-added services to commercial and institutional customers, was described. The B. C. Hydro program offers a menu of services, allowing customers to select their own combinations. Type of services included in the menu range from basic billing information to energy audits, hourly energy analysis, bill calibration, energy efficiency screening and reporting. The program was instituted in response to a need to adjust demand-side management programs as the utility industry moves towards deregulation, and subsequent increased competition. The objective of the programs is not only to retain present customers but also to pursue new customers in a more competitive environment. Details of the various service components were provided. A preliminary assessment of the program found favorable customer reception. Future evaluation programs envisage formalized participant feedback, and a determination of the direct and indirect cost-effectiveness of the BCU program. 6 figs

  10. Toward an Understanding of Motivational Influences on Prospective Memory Using Value-Added Intentions

    2015-05-01

    Full Text Available This study examined value-added intentions by manipulating the cognitive frame associated with monetary contingencies for detecting prospective memory cues. We associated a loss-frame with a monetary punishment for failing to respond to cues and a gain-frame with a monetary reward for remembering to respond to cues and compared those frames to a no-frame control condition with no contingency linked to performance. Across two experiments, we find increased prospective memory performance for participants in the loss-frame (Experiments 1 and 2 and in the gain-frame (Experiment 2 conditions relative to the no-frame condition. This value-related improvement in prospective memory was not accompanied by a significant increase in cue monitoring as measured by intention induced interference to an ongoing task and recognition memory for ongoing task items. The few previous studies investigating motivational prospective memory showed mixed results regarding whether prospective memory improves due to incentives or not. Our results provide further evidence that, under some experimental conditions, prospective memory improves with rewards and that the benefit generalizes to penalizing performance. The results have both practical implications and theoretical implications for motivation models of prospective memory.

    Full Text Available Integration is currently a key factor in intelligent transportation systems (ITS, especially because of the ever increasing service demands originating from the ITS industry and ITS users. The current ITS landscape is made up of multiple technologies that are tightly coupled, and its interoperability is extremely low, which limits ITS services generation. Given this fact, novel information technologies (IT based on the service-oriented architecture (SOA paradigm have begun to introduce new ways to address this problem. The SOA paradigm allows the construction of loosely coupled distributed systems that can help to integrate the heterogeneous systems that are part of ITS. In this paper, we focus on developing an SOA-based model for integrating information technologies (IT into ITS to achieve ITS service delivery. To develop our model, the ITS technologies and services involved were identified, catalogued, and decoupled. In doing so, we applied our SOA-based model to integrate all of the ITS technologies and services, ranging from the lowest-level technical components, such as roadside unit as a service (RSUAAS, to the most abstract ITS services that will be offered to ITS users (value-added services. To validate our model, a functionality case study that included all of the components of our model was designed.

    Food waste, as a major part of the municipal solid waste has been generated increasingly worldwide. Efficient and feasible utilization of this waste material for productivity process is significant for both economical and environmental reasons. In the present study, Musca domestica larva was used as the carrier to conduct a bioconversion with food waste to get the value-added maggot protein, oil and organic fertilizers. Methods of adult flies rearing, culture medium adjuvant selection, maggot culture conditions, stocking density and the valorization of the waste have been explored. From the experimental results, every 1000g culture mediums (700g food waste and 300g adjuvant) could be disposed by 1.5g M. domestica eggs under proper culture conditions after emergence in just 4days, 42.95±0.25% of which had been consumed and the culture medium residues could be used as good organic fertilizers, accompanying with the food waste consumption, ∼53.08g dried maggots that contained 57.06±2.19% protein and 15.07±2.03% oil had been produced. The maggot protein for its outstanding pharmacological activities is regarded as a good raw material in the field of medicine and animal feeding. Meanwhile, the maggot oil represents a potential alternative feedstock for biodiesel production. In our study, the maggot biodiesel was obtained after the procedure of transesterification reaction with methanol and the productivity was 87.71%. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The NASA Goddard Earth Sciences Data and Information Services Center (GES DISC), in addition to serving the Earth Science community as one of the major Distributed Active Archive Centers (DAACs), provides much more than just data. Among the value-added services available to general users are subsetting data spatially and/or by parameter, online analysis (to avoid downloading unnecessary all the data), and assistance in obtaining data from other centers. Services available to data producers and high-volume users include consulting on building new products with standard formats and metadata and construction of data management systems. A particularly useful service is data processing at the DISC (i.e., close to the input data) with the users' algorithms. This can take a number of different forms: as a configuration-managed algorithm within the main processing stream; as a stand-alone program next to the on-line data storage; as build-it-yourself code within the Near-Archive Data Mining (NADM) system; or as an on-the-fly analysis with simple algorithms embedded into the web-based tools. Partnerships between the GES DISC and scientists, both producers and users, allow the scientists concentrate on science, while the GES DISC handles the of data management, e.g., formats, integration and data processing. The existing data management infrastructure at the GES DISC supports a wide spectrum of options: from simple data support to sophisticated on-line analysis tools, producing economies of scale and rapid time-to-deploy. At the same time, such partnerships allow the GES DISC to serve the user community more efficiently and to better prioritize on-line holdings. Several examples of successful partnerships are described in the presentation.

    2009-12-01

    A set of computational routines called MANGO, Magnetogram Analysis for the Network of Geophysical Observatories, is utilized to calculate customized versions of the auroral electrojet indices, AE, AL, and AU. MANGO is part of an effort to enhance data services available to users of the Heliophysics VxOs, specifically for the Virtual Magnetospheric Observatory (VMO). The MANGO value-added service package is composed of a set of IDL routines that decompose ground magnetic field observations to isolate secular, diurnal, and disturbance variations of magnetic field disturbance, station-by-station. Each MANGO subroutine has been written in modular fashion to allow "plug and play"-style flexibility and each has been designed to account for failure modes and noisy data so that the programs will run to completion producing as much derived data as possible. The capabilities of the MANGO service package will be demonstrated through their application to the study of auroral electrojet current flow during magnetic substorms. Traditionally, the AE indices are calculated by using data from about twelve ground stations located at northern auroral zone latitudes spread longitudinally around the world. Magnetogram data are corrected for secular variation prior to calculating the standard version of the indices but the data are not corrected for diurnal variations. A custom version of the AE indices will be created by using the MANGO routines including a step to subtract diurnal curves from the magnetic field data at each station. The custom AE indices provide more accurate measures of auroral electrojet activity due to isolation of the sunstorm electrojet magnetic field signiture. The improvements in the accuracy of the custom AE indices over the tradition indices are largest during the northern hemisphere summer when the range of diurnal variation reaches its maximum.

    Full Text Available Background: Economic value added (EVA may reflect true performance compared with other conventional accounting indices, it is still measured through financial statements. It is highly probable that EVA motivates managers to manipulate earnings. Aim: The main contribution of this study is the analysis of the association between earnings management and EVA. This study provides shareholders, lenders and creditors (or other categories of investors with a method for analysing the value of enterprises. Setting: We analyse the association between earnings management through real earnings management (REM or discretionary accrual (DA activities and the EVA by African and the Group of Twenty (G20 nations. Methods: The sample for this study was obtained from the COMPUSTAT database between 2009 and 2013. This study also adopted the ordinary least squares (OLS method. Results: The results indicate that a significantly positive relationship exists between earnings management through DA items and EVA in African nations. In addition, a significantly negative relationship exists between earnings management through DA items or REM activities and EVA in G20 nations. Conclusion: Our results provide critical implications for managers, researchers, investors and regulators of various nations; for example, managers may determine whether to increase the EVA through earnings management, researchers may analyse varying degrees of REM activities and DAs existing in the same nation groups or regulators may determine how to establish laws or rules to prevent earnings management because it is likely that differences in national development, culture or politics exist in these nations.

    "Waste is wasted if you waste it, otherwise it is a resource. Resource is wasted if you ignore it and do not conserve it with holistic best practices and reduce societal costs. Resource is for the transformation of people and society." Red mud is a worldwide problem with reserves in the hundreds of millions of tons and tens of millions of tons being added annually. Currently there is not an effective way to deal with this byproduct of the Bayer Process, the primary means of refining bauxite ore in order to provide alumina. This alumina is then treated by electrolysis using the Hall-Heroult process to produce elemental aluminum. The resulting mud is a mixture of solid and metallic oxides, and has proven to be a great disposal problem. This disposal problem is compounded by the fact that the typical bauxite processing plant produces up to three times as much red mud as alumina. Current practice of disposal is to store red mud in retention ponds until an economical fix can be discovered. The danger associated with this current method of storage is immense to the surrounding communities and environment, thus the interest from the Center for Resource Recovery and Recycling (CR3). The purpose of this document is to explain one way to remove the value added materials, primarily iron, from the Jamaican red mud using both pyrometallurgical and hydrometallurgical approaches. In the beginning, soda ash and carbon roasting were completed simultaneously at 800°C. This type of roasting produced results that were unacceptable. After the soda ash roast was completed independently of carbon roasting, a water wash produced results that separations of alumina at 90%, Iron at 99%, calcium at 99%, titanium t 100%, and sodium by 74%. Smelting produced separations of 97% for alumina, 99% for iron, 87% for sodium, 94% for calcium and 72% for titanium.

    The rapid population aging is now a global issue. The increase in the elderly population will impact the health care industry and health enterprises; various senior needs will promote the growth of the senior health industry. Most senior health studies are focused on the demand side and scarcely on supply. Our study selected quality enterprises focused on aging health and analyzed different strategies to provide excellent quality services to senior health enterprises. We selected 33 quality senior health enterprises in Taiwan and investigated their excellent quality services strategies by face-to-face semi-structured in-depth interviews with CEO and managers of each enterprise in 2013. A total of 33 senior health enterprises in Taiwan. Overall, 65 CEOs and managers of 33 enterprises were interviewed individually. None. Core values and vision, organization structure, quality services provided, strategies for quality services. This study's results indicated four type of value-added strategy models adopted by senior enterprises to offer quality services: (i) residential care and co-residence model, (ii) home care and living in place model, (iii) community e-business experience model and (iv) virtual and physical portable device model. The common part in these four strategy models is that the services provided are elderly centered. These models offer virtual and physical integrations, and also offer total solutions for the elderly and their caregivers. Through investigation of successful strategy models for providing quality services to seniors, we identified opportunities to develop innovative service models and successful characteristics, also policy implications were summarized. The observations from this study will serve as a primary evidenced base for enterprises developing their senior market and, also for promoting the value co-creation possibility through dialogue between customers and those that deliver service. © The Author 2017.

    Full Text Available Background: Value added services (VAS are an innovative dispensing system created to provide an alternative means of collecting partial drug supply from our hospital. This in turn was projected to reduce the necessity for patient to visit pharmacy counter and thus reduce the burden of prescription handling. Objective: To evaluate the impact of increased VAS uptake following promotional campaign towards patient waiting time and to explore factors that may affect patient waiting time at the Ambulatory Pharmacy, Queen Elizabeth Hospital. Methods: A quasi experimental study design was conducted from September 2014 till June 2015 at the Ambulatory Pharmacy. During pre-intervention phase, baseline parameters were collected retrospectively. Then, VAS promotional campaign was carried out for six months and whilst this was done, the primary outcome of patient waiting time was measured by percentage of prescription served less than 30 minutes. A linear regression analysis was used to determine the impact of increased VAS uptake towards patient waiting time. Results: An increased in percentage of VAS registration (20.9% vs 35.7%, p<0.001 was observed after the promotional campaign. The mean percentage of prescription served less than 30 minutes increased from 83.2% SD=15.9 to 90.3% SD=11.5, p=0.001. After controlling for covariates, it was found that patient waiting time was affected by number of pharmacy technicians (b=-0.0349, 95%CI-0.0548 : -0.0150, p=0.001, number of pharmacy counters (b=0.1125, 95%CI 0.0631 : 0.1620, p<0.001, number of prescriptions (b=0.0008, 95%CI 0.0004 : 0.0011, p<0.001, and number of refill prescriptions (b=0.0004, 95%CI 0.0002 : 0.0007, p<0.001. The increased in percentage of VAS registration was associated with reduction in number of refill prescription (b=-2.9838, 95%CI -4.2289 : -1.7388, p<0.001. Conclusions: Patient waiting time at the Ambulatory Pharmacy improved with the increased in VAS registration. The impact of

    It has been challenging to directly compare U.S. Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) Climate Research Facility ground-based cloud radar measurements with climate model output because of limitations or features of the observing processes and the spatial gap between model and the single-point measurements. To facilitate the use of ARM radar data in numerical models, an ARM cloud radar simulator was developed to converts model data into pseudo-ARM cloud radar observations that mimic the instrument view of a narrow atmospheric column (as compared to a large global climate model [GCM] grid-cell), thus allowing meaningful comparison between model output and ARM cloud observations. The ARM cloud radar simulator value-added product (VAP) was developed based on the CloudSat simulator contained in the community satellite simulator package, the Cloud Feedback Model Intercomparison Project (CFMIP) Observation Simulator Package (COSP) (Bodas-Salcedo et al., 2011), which has been widely used in climate model evaluation with satellite data (Klein et al., 2013, Zhang et al., 2010). The essential part of the CloudSat simulator is the QuickBeam radar simulator that is used to produce CloudSat-like radar reflectivity, but is capable of simulating reflectivity for other radars (Marchand et al., 2009; Haynes et al., 2007). Adapting QuickBeam to the ARM cloud radar simulator within COSP required two primary changes: one was to set the frequency to 35 GHz for the ARM Ka-band cloud radar, as opposed to 94 GHz used for the CloudSat W-band radar, and the second was to invert the view from the ground to space so as to attenuate the beam correctly. In addition, the ARM cloud radar simulator uses a finer vertical resolution (100 m compared to 500 m for CloudSat) to resolve the more detailed structure of clouds captured by the ARM radars. The ARM simulator has been developed following the COSP workflow (Figure 1) and using the capabilities available in COSP

    Sustainable dairy production requires farms that are economically viable, environmentally sound and socially acceptable. A low environmental impact of milk production is not necessarily associated with an economically viable farm. To gain insight into a possible trade-off between economic and environmental sustainability, the relation between the environmental and economic indicators of dairy farms was quantified, and farm characteristics that influence this relation were identified. Economic and environmental indicators were quantified for 119 specialized dairy farms in 2005, based on data from the Dutch Farm Accountancy Data Network (FADN). Economic indicators used were: gross value added expressed per kg fat-and-protein-corrected milk (FPCM) or expressed per unit of labour, i.e. labour productivity. Environmental indicators used were: land use per kg FPCM, energy use per kg FPCM, global warming potential per kg FPCM, eutrophication and acidification potential per kg FPCM or per ha of land. Environmental indicators were deduced from a life cycle assessment. High labour productivity on dairy farms was associated with low on-farm energy use, total and on-farm land use, total and on-farm global warming potential, and total and off-farm acidification potential per kg FPCM. High labour productivity, however, was associated also with high on-farm eutrophication and acidification potential per hectare. From partial least squares regression analysis, it was concluded that relations between economic and environmental indicators were affected mainly by milk production per ha, annual milk production per cow, farm size, and amount of concentrates per kg FPCM. An increase in annual milk production per cow, for example, not only increased labour productivity, reduced energy use and global warming potential per kg FPCM but also, in the case of an unchanged stocking density, increased eutrophication and acidification per ha. To be economically and environmentally sustainable

    This paper examines a tax jurisdiction issue of the consumption tax system with regard to Japanese service trading. The Destination principle for service trading has not been established in Japanese consumption tax, but taxation at the place of consumption is gradually being adopted for value-added taxes in the EU. Under these circumstances, it is necessary for us to revise the Japanese consumption tax system in favor of taxation at the place of consumption, using EU-type value-added tax syst...

    Previous studies found lower substance use in schools achieving better examination and truancy results than expected, given their pupil populations (high value-added schools). This study examines whether these findings are replicated in West Scotland and whether school ethos indicators focussing on pupils' perceptions of schooling (environment, involvement, engagement and teacher–pupil relations) mediate the associations. Teenagers from forty-one schools (S2, aged 13, n = 2268; S4, aged 15, n = 2096) previously surveyed in primary school (aged 11, n = 2482) were surveyed in the late 1990s. School value-added scores were derived from standardised residuals of two regression equations separately predicting from pupils' socio-demographic characteristics (1) proportions of pupils passing five Scottish Standard Grade Examinations, and (2) half-day truancy loss. Outcomes were current smoking, monthly drinking, ever illicit drug use. Random effects logistic regression models adjusted for potential pupil-level confounders were used to assess (1) associations between substance use and school-level value-added scores and (2) whether these associations were mediated by pupils' perceptions of schooling or other school-level factors (school roll, religious denomination and mean aggregated school-level ethos scores). Against expectations, value-added education was positively associated with smoking (Odds Ratios [95% confidence intervals] for one standard deviation increase in value-added scores were 1.28 [1.02–1.61] in S2 and 1.13 [1.00–1.27] in S4) and positively but weakly and non-significantly associated with drinking and drug use. Engagement and positive teacher–pupil relations were strongly and negatively associated with all substance use outcomes at both ages. Other school-level factors appeared weakly and largely non-significantly related to substance use. Value-added scores were unrelated to school ethos measures and no ethos measure mediated associations

    Full Text Available Science One is a full academic year interdisciplinary alternative to the traditional first-year experience in the Faculty of Science at the University of British Columbia (UBC. Anecdotal reports suggest that alumni/ae of the program do very well in upper-level classes and many become successful graduate and medical students. The high faculty/student ratio makes the program an expensive one, however, and thus we have sought rigorous evidence of the benefits to our students. Our approach has been a value-added one; we have compared high-school and upper-level undergraduate grades for students in all UBC's first-year science programs. We have found a clear signal that there is a large benefit to participating in Science One, and conclude that this arises from a combination of the recruitment of enthusiastic students who are up for a challenge, the Science One admissions process, and taking the program itself.Science One consiste en une année scolaire interdisciplinaire complète qui représente une variante de l’expérience traditionnelle vécue en première année à la Faculté des sciences de l’Université de la Colombie-Britannique (UBC. Des rapports isolés suggèrent que les anciens étudiants du programme obtiennent de très bons résultats dans les cours de niveau supérieur et plusieurs obtiennent leur diplôme avec succès et étudient en médecine. Cependant, le ratio élevé enseignant/étudiant fait en sorte que le programme coûte cher, c’est pourquoi les auteurs ont cherché à obtenir des données probantes sur les avantages qu’il présente pour leurs étudiants. Ils ont employé la méthode de la valeur ajoutée; ont comparé les notes obtenues au secondaire et celles des étudiants de premier cycle inscrits à des cours de niveau supérieur dans tous les programmes scientifiques offerts à l’UBC. Ils ont découvert que la participation à Science One est très bénéfique et ont conclu que cela résulte d

  6. The Effect of Macroeconomic Variables on Value-Added Agriculture: Approach of Vector Autoregresive Bayesian Model (BVAR

    Full Text Available There are different ideas and opinions about the effects of macroeconomic variables on real and nominal variables. To answer the question of whether changes in macroeconomic variables as a political tool is useful over a business cycle, understanding the effect of macroeconomic variables on economic growth is important. In the present study, the Bayesian Vector autoregresive model and seasonality data for the years between 1991 and 2013 was used to determine the impact of monetary policy on value-added agriculture. Predicts of Vector autoregresive model are usually divertaed due to a lot of parameters in the model. Bayesian vector autoregresive model estimates more reliable predictions due to reducing the number of included parametrs and considering the former models. Compared to the Vector Autoregressive model, the coefficients are estimated more accurately. Based on the results of RMSE in this study, previous function Nrmal-Vyshart was identified as a suitable previous disteribution. According to the results of the impulse response function, the sudden effects of shocks in macroeconomic variables on the value added in agriculture and domestic venture capital are stable. The effects on the exchange rates, tax revenues and monetary will bemoderated after 7, 5 and 4periods. Monetary policy shocks ,in the first half of the year, increased the value added of agriculture, while in the second half of the year had a depressing effect on the value added.

  15. Value Added Service and Service Quality from the Customer’s Perspective: An Empirical Investigation in Thai Telecommunication Industry

    Directory of Open Access Journals (Sweden)

    Saowanee Srikanjanarak

    2009-12-01

    Full Text Available Increasing global competition has led to an intensively competitive market among service providers. Several organizations have created and developed a variety of products or services; in particular the telecommunications industry has developed mobile phone services. Various value-added services linked to mobile phone services, such as communication, entertainment, information services and money transfer services have been intensively incorporated to sustain and serve the customer’s need, which in turn demands performance maximization. In service marketing literature, SERVQUAL and SERVPERF have been reported as failing to measure service quality in new industries such as the retail industry’s B2B service. Therefore, service quality models for the mobile phone service industry need to be further developed.Service quality models have placed little focus on value-added services and no research has yet operationalized the concept of value-added services in a service quality model from the customer’s perspective of the service industry. Hence, this paper aims to conceptualize a service quality model based on Gronroos’ Model, other exploratory research and the current market situation in the service context. A total of 998 structured questionnaires were distributed to pre-paid mobile phones users in nine provinces around Thailand. The results indicate four dimensions of service quality. The value-added services have shown a particularly high level of measurements of satisfaction. These findings reveal a meaningful insight into how customers perceive the value-added services offered by service providers. This will help managers to design an appropriate variety of service options that suit their customers and in turn may lead to the development of a long-term relationship with their organizations.

  16. Shell cracking strength in almond (Prunus dulcis [Mill.] D.A. Webb.) and its implication in uses as a value-added product.

    Researchers are currently developing new value-added uses for almond shells, an abundant agricultural by-product. Almond varieties are distinguished by processors as being either hard or soft shelled, but these two broad classes of almond also exhibit varietal diversity in shell morphology and physical characters. By defining more precisely the physical and chemical characteristics of almond shells from different varieties, researchers will better understand which specific shell types are best suited for specific industrial processes. Eight diverse almond accessions were evaluated in two consecutive harvest seasons for nut and kernel weight, kernel percentage and shell cracking strength. Shell bulk density was evaluated in a separate year. Harvest year by almond accession interactions were highly significant (p0.01) for each of the analyzed variables. Significant (p0.01) correlations were noted for average nut weight with kernel weight, kernel percentage and shell cracking strength. A significant (p0.01) negative correlation for shell cracking strength with kernel percentage was noted. In some cases shell cracking strength was independent of the kernel percentage which suggests that either variety compositional differences or shell morphology affect the shell cracking strength. The varietal characterization of almond shell materials will assist in determining the best value-added uses for this abundant agricultural by-product.

    2013-08-01

    This paper focuses on the characterization of the materials of a violin top plate made by Antonio Stradivari (17th century), with different diagnostic techniques and with an integrated and non-destructive analytical methodology to study surface coatings and decorations. The UV-induced visible fluorescence, optical digital microscopy, ED-XRF associated with micro-FTIR spectroscopy analysis, and dendrochronology were performed. The investigations were aimed to identify the presence of original varnish layers and to characterize the composition of the decorations, either the inlaid purflings or the composite false-inlay strip between them. Several results were achieved: (i) evidence of the absence of varnish layers on the surface as a result of extended and inappropriate restoring; (ii) identification of the dye used for the black layers of the purflings; (iii) characterization of the black matrix and the white elements of the decoration. Furthermore, a dendrochronological dating was performed. A copy of the top plate was realized with materials similar to those identified on the Stradivari original; the same analyses performed on the original model were carried out on the same areas of the copy.

    Energy fuels for transportation and electricity generation are mainly derived from finite and declining reserves of fossil hydrocarbons. Fossil hydrocarbons are also used to produce a wide range of organic carbon-based chemical products. The current global dependency on fossil hydrocarbons will not be environmentally or economically sustainable in the long term. Given the future pessimistic prospects regarding the complete dependency on fossil fuels, political and economic incentives to develop carbon neutral and sustainable alternatives to fossil fuels have been increasing throughout the world. For example, interest in biodiesel has undergone a revival in recent times. However, the disposal of crude glycerol contaminated with methanol, salts, and free fatty acids as a by-product of biodiesel production presents an environmental and economic challenge. Although pure glycerol can be utilized in the cosmetics, tobacco, pharmaceutical, and food industries (among others), the industrial purification of crude glycerol is not economically viable. However, crude glycerol could be used as an organic carbon substrate for the production of high-value chemicals such as 1,3-propanediol, organic acids, or polyols. Microorganisms have been employed to produce such high-value chemicals and the objective of this article is to provide an overview of studies on the utilization of crude glycerol by microorganisms for the production of economically valuable products. Glycerol as a by-product of biodiesel production could be used a feedstock for the manufacture of many products that are currently produced by the petroleum-based chemical industry.

    2013-03-13

    The chemical composition of dwarf French bean (Phaseolus vulgaris L.) cv. Top Crop was compared among five production systems: conventional, integrated, organic, and biodynamic production systems and the control. Determination of sugars and organic acids was performed with a HPLC system, and identification of individual phenolic compounds using HPLC-MS. The chemical composition of the beans was unaffected by the production systems; however, the content levels of individual compounds were changed. The pods from integrated production contained the lowest levels of glucose and sucrose and the highest levels of catechin, procyanidin dimers, and a vanillic acid derivative. The control treatment, as well as organic and biodynamic productions, positively affected the levels of sugar content and caused a lower content of catechin and trans-p-coumaroylaldaric acids. Beans from the conventional production system contained the lowest levels of fructose, glucose, ascorbic acid, and many phenolics from various groups.

    2015-11-01

    The global forestry industry after experiencing a market downturn during the past decade has now aimed its vision towards the integrated biorefinery. New business models and strategies are constantly being explored to re-invent the global wood and pulp/paper industry through sustainable resource exploitation. The goal is to produce diversified, innovative and revenue generating product lines using on-site bioresources (wood and tree residues). The most popular product lines are generally produced from wood fibers (biofuels, pulp/paper, biomaterials, and bio/chemicals). However, the bark and other tree residues like foliage that constitute forest wastes, still remain largely an underexploited resource from which extractives and phytochemicals can be harnessed as by-products (biopharmaceuticals, food additives and nutraceuticals, biopesticides, cosmetics). Commercially, Populus (poplar) tree species including hybrid varieties are cultivated as a fast growing bioenergy crop, but can also be utilized to produce bio-based chemicals. This review identifies and underlines the potential of natural products (phytochemicals) from Populus species that could lead to new business ventures in biorefineries and contribute to the bioeconomy. In brief, this review highlights the importance of by-products/co-products in forest industries, methods that can be employed to extract and purify poplar phytochemicals, the potential pharmaceutical and other uses of >160 phytochemicals identified from poplar species - their chemical structures, properties and bioactivities, the challenges and limitations of utilizing poplar phytochemicals, and potential commercial opportunities. Finally, the overall discussion and conclusion are made considering the recent biotechnological advances in phytochemical research to indicate the areas for future commercial applications from poplar tree species.

    During the past decade, there has been increasing global concern over the rise of anthropogenic CO 2 emission into the Earth's atmosphere (J Air Waste Manage Assoc 53:645-715, 2003). The utilization of CO 2 to produce any valuable product is need of the hour. The production of syngas from CO 2 and CH 4 seems to be one of the promising alternatives in terms of industrial utilization, as it offers several advantages: (a) mitigation of CO 2 , (b) transformation of natural gas and CO 2 into valuable syngas, and (c) producing syngas with H 2 /CO ratio 1 which may further be used for the production of valuable petrochemicals (J Air Waste Manage Assoc 53:645-715, 2003). A conceptual design for the production of synthesis gas by dry reforming of methane is presented here. An economic assessment of this process with an integrated methanol production section as a case was conceptualized and compared with the conventional steam methane reforming route to produce methanol. The economic study indicated that dry reforming of natural gas/methane is a competitive process with lower operating and capital costs in comparison with steam reforming assuming negligible cost of CO 2 import.

    2013-07-31

    Three methods are described to fractionate condensed distillers solubles (CDS) into several new coproducts, including a protein-mineral fraction and a glycerol fraction by a chemical method; a protein fraction, an oil fraction and a glycerol-mineral fraction by a physical method; or a protein fraction, an oil fraction, a mineral fraction, and a glycerol fraction by a physicochemical method. Processing factors (ethanol concentration and centrifuge force) were also investigated. Results show that the three methods separated CDS into different fractions, with each fraction enriched with one or more of the five components (protein, oil, ash, glycerol and other carbohydrates) and thus having different targeted end uses. Furthermore, because glycerol, a hygroscopic substance, was mostly shifted to the glycerol or glycerol-mineral fraction, the other fractions had much faster moisture reduction rates than CDS upon drying in a forced air oven at 60 °C. Thus, these methods could effectively solve the dewatering problem of CDS, allowing elimination of the current industrial practice of blending distiller wet grains with CDS for drying together and production of distiller dried grains as a standalone coproduct in addition to a few new fractions.

    Black tilapia (Oreochromis mossambicus) fish head bones were evaluated for its possibilities in extracting gelatin. Head bones were subjected to pre-treatment with 3% of hydrochloric acid (HCl) for demineralization before undergoes thermal extraction process. The raw head bones were characterized via Scanning Electron Microscopy (SEM) in order to investigate the external and internal surface morphology. SEM images also reveal the presence of collagen fiber with 1 µm diameter in the head bone. The black tilapia fish head bones yields 5.75 % of gelatin in wet weight basis, indicating the possibility of this fish species as sources of gelatin. Further characterizations were done on both raw head bones and extracted gelatin through Fourier Transform Infrared Spectroscopy (FTIR) and proximate analysis. The head bones gelatin shows high protein (10.55%) and ash (3.11 %) content with low moisture. This further proves the effectiveness of demineralization and extraction method used. The black tilapia fish head bones are found to be a prospective source of gelatin with good chemical and functional properties.

    are representative in the physical
built environment of hospitals. This is possible by comparing the results of design assessment with measures of user experiences in actual buildings, e.g. by building-in- use studies or so-called Post-Occupancy Evaluations (POE. Toolbox to support value adding management & design One of the results of this research is the design of a toolbox that can contribute to
the decision-making regarding accommodation for hospitals. This toolbox provides
a structure for the context, value, design and management of accommodation and is intended as a reference for the alignment between real estate and the organisation
of healthcare. The instruments can be used independently of each other, but can
also be combined. As such, the toolbox provides guidelines for the distribution of responsibilities and tasks between the hospital board, real estate manager, healthcare managers and architects in various phases of occupancy, initiative and design. Existing frameworks as the starting point The case studies demonstrate the usefulness of the conceptual models of CREM in matching accommodation for hospitals and the organisation of healthcare. The model for context-mapping provides a starting point for getting a grip on the position of real estate in the dynamic context of hospitals. The arrangement of different conceptual models in the meta-model and the link to the EFQM model as an abstract description of the organisation results in a roadmap in which the accommodation and organisation of healthcare can be coordinated iteratively. While the meta-model at the level of the CEO provides an overview and outline of the considerations to be made, the integrating framework is a comprehensive tool for real estate managers to further elaborate on these various steps. Generic values from the literature are discussed and translated into the sector-specific added value of hospital real estate. In addition, design assessment makes it possible to test various

    Electrical properties of (Bs,Sr)TiO3 (BST) thin films are characterized with sputtered and metal organic chemical vapor deposited (MOCVD) Pt top electrodes. BST films with MOCVD Pt top electrodes, which were deposited using Pt(CF3COCHCOCF3)2 (Pt-HFA) as a precursor, showed less leakage current without bulged curves and a higher dielectric constant than those with sputtered Pt top electrodes. The improvement of electrical properties seems to result from the reduction of interface trap sites with the incorporation of fluorine atoms from HFA ligands.

  15. Value-Added-Based Accounting of CO2 Emissions: A Multi-Regional Input-Output Approach

    2017-12-01

    Full Text Available In the era of globalization and international trade, the production-based CO2 emissions accounting system, proposed by United Nations Framework Convention on Climate Change, can easily lead to a “carbon leakage” issue. Thus, the accounting of consumption-based carbon emissions and carbon emissions embodied in international trade has received considerable research attention. Nevertheless, researchers also indicated that the consumption-based principle has some weaknesses, for example, it leads the producers inert on reducing carbon emissions while gaining economic benefits. To share carbon emissions responsibilities between producers and consumers is widely recognized. So, setting an income-based emissions accounting method as to producer is a necessary complement for accounting national carbon emissions. This study promoted a model, called the value-added-based accounting of CO2 emissions method, to account for anthropogenic CO2 emissions within the context of the economic benefit principle. Based on the global multi-regional input-output table and national carbon emissions database, we calculated the national/regional carbon emissions based on the value-added accounting approach as well as the amount of global carbon emissions embodied in value-added chains. If the results are served as a supplement for calculating the amount of CO2 emissions reduction that a country is responsible for, problems such as carbon leakage and resistance to improving the energy efficiency of exporting sector may be solved, because all the supply chains emissions associated with the economic growth of a country would be considered.

    Solid waste management is a worldwide problem and it is becoming more and more complicated day by day due to rise in population, industrialization and changes in our life style. Transformation of industrial sludges into vermicompost is of double interest: on the one hand, a waste is converted into value added product, and, on the other, it controls a pollutant that is a consequence of increasing industrialization. Garden waste, kitchen waste and cow dung were subjected to recycle through vermicomposting by using the epigeic earthworm Eisenia fetida under field conditions. The pH, moisture content, total organic carbon, humus, nitrogen, phosphorous and potassium in vermicompost was analysed. It was found that moisture content, total organic carbon, humus, nitrogen, phosphorous and potassium was high in cow dung, followed by kitchen waste and garden waste. This study clearly indicates that vermicomposting of garden waste, kitchen waste and cow dung can not only produce a value added produce (vermicomposting) but at the same time reduce the quantity of waste.

    Objectives: To eliminate non-value-adding (NVA) waste for the procurement of endovascular stents in interventional radiology services by applying value stream mapping (VSM). Materials and methods: The Lean manufacturing technique was used to analyze the process of material and information flow currently required to direct endovascular stents from external suppliers to patients. Based on a decision point analysis for the procurement of stents in the hospital, a present state VSM was drawn. After assessment of the current status VSM and progressive elimination of unnecessary NVA waste, a future state VSM was drawn. Results: The current state VSM demonstrated that out of 13 processes for the procurement of stents only 2 processes were value-adding. Out of the NVA processes 5 processes were unnecessary NVA activities, which could be eliminated. The decision point analysis demonstrated that the procurement of stents was mainly a forecast driven push system. The future state VSM applies a pull inventory control system to trigger the movement of a unit after withdrawal by using a consignment stock. Conclusion: VSM is a visualization tool for the supply chain and value stream, based on the Toyota Production System and greatly assists in successfully implementing a Lean system.

    Manure produced from confined animal farms can threaten public and environmental health if not managed properly. Herein, a full-scale commercial bioconversion operation in DeQing County, China for value-added swine manure reduction using house fly, Musca domestica L., larvae is reported. The greenhouse-assisted larvae bioreactor had a maximum daily treatment capacity of 35 m(3) fresh raw manure per day. The bioconversion process produced a fresh larvae yield of 95-120 kg m(3) fresh raw manure. This process provided an alternative animal foodstuff (having 56.9 and 23.8% protein and total fat as dry matter, respectively), as well as captured nutrients for agricultural re-utilization. Bioconversion reduced odour emission (characterized by 3-methylindole) and the Escherichia coli (E. coli) index by 94.5 and 92.0%, respectively, and reductions in total weight, moisture and total Kjeldahl nitrogen in solids were over 67.2, 80.0 and 76.0%, respectively. Yearly profit under this trial period ranged from US$33.4-46.1 per m(3). It is concluded that swine manure larvae bioconversion technology with subsequent production of value-added bio-products can be a promising avenue when considering a programme to reduce waste products in an intensive animal production system.

    Health care reform in the United States has generated a paradigm shift in the practice of radiology aimed at increasing the degree of patient-centered care. We conducted a study to quantify the amount of time breast imaging radiologists spend on value-added activities at an academic comprehensive cancer center located in Miami, Florida, and accredited by the American College of Radiology as a Breast Imaging Center of Excellence. A prospective, observational study was conducted during a period of 20 consecutive workdays. Three participating breast imaging radiologists maintained a real-time log of each activity performed. A generalized linear model was used to perform a 1-way analysis of variance. An alpha level of .05 was used to determine statistical significance. The average daily time dedicated to these activities was 92.1 minutes (range, 56.4-132.2). The amount of time significantly differed among breast imaging radiologists and correlated with their assigned daily role (P value-added activities to help improve patients' experience across the continuity of their care. We propose that similar studies be conducted at other institutions to better assess the magnitude of this finding across different breast imaging care settings.

    Full Text Available Abstract Background Health information technology (HIT applications that incorporate point-of-care use of health-related quality of life (HRQL assessments are believed to promote patient-centered interactions between seriously ill patients and physicians. However, it is unclear how willing primary care providers are to use such HRQL HIT applications. The specific aim of this study was to explore factors that providers consider when assessing the value added of an HRQL application for their geriatric patients. Methods Three case studies were developed using the following data sources: baseline surveys with providers and staff, observations of staff and patients, audio recordings of patient-provider interactions, and semi-structured interviews with providers and staff. Results The primary factors providers considered when assessing value added were whether the HRQL information from the module was (1 duplicative of information gathered via other means during the encounter; (2 specific enough to be useful and/or acted upon, and; (3 useful for enough patients to warrant time spent reviewing it for all geriatric patients. Secondary considerations included level of integration of the HRQL and EHR, impact on nursing workflow, and patient reluctance to provide HRQL information. Conclusions Health-related quality of life modules within electronic health record systems offer the potential benefit of improving patient centeredness and quality of care. However, the modules must provide benefits that are substantial and prominent in order for physicians to decide that they are worthwhile and sustainable. Implications of this study for future research include the identification of perceived "costs" as well as a foundation for operationalizing the concept of "usefulness" in the context of such modules. Finally, developers of these modules may need to make their products customizable for practices to account for variation in EHR capabilities and practice

The value added is a value that increases due to a commodity that has been processed transported or stored in a production. Lamongan and Pelabuhanratu regencies are one of fisheries centers on the north and the south coast of Java Island. The aim of this research was to know the value added and the business margin of fisheries from the processing and marketing aspects. The research was carried out in two locations Northern coast Lamongan regencies and Shouther coasts Pelabuhanratu regencies Indoneisa. The data used were primary data the people involved in the business including fishing marketing and processing product. The results showed that the process of fisheries product yielded the value added and margin that were created from the incorporation of business benefit added input contribution other input and direct reward for the labor forces. The value added and the business margin of product processing can reach 2 to 3 fold from the main input value. The value added and the business margin of fisheries product processing were very big. This was the source of economy growth there. The effort to develop the business of fisheries product processing in the small scale need to be supported with various programs especially in the market access and funding.

    This study aimed at estimating the consumer's willingness to pay (WTP) more for value-added pomegranate juice using the contingent valuation method (CVM). The WTP was estimated applying the open-ended elicitation technique with 454 consumers in two supermarkets located in Rio de Janeiro, Brazil. The average consumer's WTP more for pomegranate juice was estimated in R$2.04 (Brazilian currency) and the income elasticity coefficient at the midpoint was 0.19, i.e., a 10% increase in consumer income will increase, on average, 1.9% the WTP of pomegranate juice (ceteris paribus). Therefore, the income elasticity coefficient was considered inelastic, once an increase in income would have low effect on the WTP for these consumers. The results indicated that the consumers were interested in acquiring a non-traditional juice processed using a technology that preserves vitamins and antioxidants, maintains the flavor of "fresh juice" without colorants and preservatives, despite the pomegranate is not part of the Brazilian diet.

    Varsha Bangalee

    2017-10-01

    Full Text Available Background: Despite the important and essential role that medicines play in any society, all medicines, including those identified as essential, are uniformly subjected to 14% value added tax (VAT, regardless of their therapeutic value in the private healthcare sector of South Africa. The aim of this article is to demonstrate the potential cost-saving attained from the removal of VAT from the private sector pricing of essential medicines, using antiretroviral treatment as an example. Methods: An empirical analysis was undertaken to illustrate the potential cost-saving achieved by removing VAT from the Single Exit Price and the dispensing fee of essential medicines. This outcome was demonstrated by applying the methodology to an adult fixed dose combination 1st line antiretroviral regimen as well as to a group of 3rd line antiretroviral medicines. Results: The potential saving for the lowest priced generic and originator 1st line antiviral regimen accrued to ZAR 693.84 and ZAR 1085.04 over a year respectively. Regarding the 3rd line antiretroviral drugs, results yielded an annual saving of ZAR 1678.68 (darunavir, ZAR5741.04 (maraviroc and ZAR 159.48 (rilpivirine. Conclusions: Lobbying for the removal of VAT from the supply chain of medicines should be intensified. Policy development to monitor and recover lost government revenue through the removal of taxes should be explored.

    In this study, a co-production of two high value-added products, glucose and xylooligosaccharides (XOS), was investigated by utilizing sugarcane bagasse (SB) within a multi-product bio-refinery framework optimized by Box-Behnken design-based response surface methodology. The developed process resulted in a maximum cellulose conversion of xylan-removed SB, 98.69±1.30%, and a maximum extracted SB xylan conversion into XOS (xylobiose and xylotriose) of 57.36±0.79% that was the highest SB xylan conversion reported in the literature, employing cellulase from Penicillium oxalicum EU2106 and recombinant endo-β-1,4-xylanase in Pichia pastoris. Consequently, a mass balance analysis showed that the maximum yields of glucose and XOS were 34.43±0.32g and 5.96±0.09 g per 100 g raw SB. Overall, this described process may be a preferred option for the comprehensive utilization of SB. Copyright © 2016 Elsevier Ltd. All rights reserved.

  15. Value-added benefits of technology: e-procurement and e-commerce related to the health care industry.

    2005-01-01

    To provide insights into the current supply chain for original equipment manufacturers (OEM) in the radiology diagnostic imaging equipment business. As is common in many manufacturing and service firms, the rationale of bridging suppliers of OEMs is the ability to leverage technology, software, and accessories pertaining to the various pieces of equipment. Several models of e-procurement and e-commerce related to the health care industry are presented. Although the radiology capital equipment market presents numerous idiosyncrasies that must be addressed to successfully implement an e-business strategy effectively, incredible opportunities exist all along the supply chain for e-business strategies to both eliminate costs and acquire strategic initiatives. Those firms that most successfully listen to their customers and address the barriers to efficiency (B2E) will help move the industry toward more effective utilization of the benefits e-business can create and also obtain first mover advantages. Although the efficiencies that e-business provides are extremely important in the radiology capital equipment market, the main value of e-business in this industry of high-priced and relatively infrequently purchased equipment may well be the value-added benefits the technology brings to its customers, as illustrated in the modeling process. The OEMs that eventually market their finished product directly to hospital and imaging centers via a direct sales force can best take advantage of the connectivity and accessibility of e-commerce.

    Successful valorisation of raspberry and blueberry pomace was achieved through their application, as dried and ground powders, in the formulation of value-added gluten-free cookies. Simplex-lattice mixture design approach was applied to obtain the product with the best sensory properties, nutritional profile and antioxidant activity. The highest desirability of 90.0 % was accomplished with the substitution of gluten-free flour mixture with 28.2 % of blueberry and 1.8 % of raspberry pomace. The model was verified. Optimized cookies had similar protein (3.72 %) and carbohydrate (66.7 %) contents as gluten-containing counterparts used for comparison, but significantly lower fat content (10.97 %). Daily portion of the optimized cookies meets: 5.00 % and 7.73 % of dietary reference intakes (DRIs) for linoleic acid, 23.6 % and 34.3 % of DRIs for α-linolenic acid and 10.3 % and 15.6 % of DRIs for dietary fibers, for male and female adults, respectively. The nutritional profile of the optimized formulation makes it comparable with added-value gluten-containing counterparts.

    State value-added taxes (VAT) on tobacco products have been increased significantly in recent years in India. Evidence on how these VATs were associated with smoking is highly needed. State bidi and cigarette VAT rates were linked to Global Adult Tobacco Survey (GATS) India 2009-2010 and Tobacco Control Policy (TCP) India Survey waves 1 (2010-2011) and 2 (2012-2013), respectively. These linked data were used to analyze the associations between bidi VAT rates and bidi smoking, between cigarette VAT rates and cigarette smoking, and between the two VAT rates and dual use of bidis and cigarettes. Weighted logistic regressions were employed to examine GATS cross-sectional data, whereas Generalized Estimating Equations (GEE) were employed to examine longitudinal TCP data. We further stratified the analyses by gender. A 10% increase in cigarette VAT rates was associated with a 6.5% (pHigher state cigarette VAT rates in India were significantly associated with lower cigarette smoking and lower dual use of cigarettes and bidis.

    2017-05-01

    In this study, conversion of sewage sludge to biogas by anaerobic co-digestion with crude glycerol was examined. When 0.126g/L crude glycerol was added to the reactor, only methane was produced. Upon addition of 5.04g/L crude glycerol, hydrogen production occurred, and a significant amount of 1,3-propanediol (1,3-PDO) was generated in the liquid phase. On day 6, the dry weight was largely composed of organic acids (48%) and 1,3-PDO (17%), which are water-soluble. Degradation of 1,3-PDO was very slow, which is advantageous for recovery. Crude glycerol, which contains alkaline substances, promoted organic matter degradation by microorganisms, which possibly affected biogas and 1,3-PDO production. Addition of 0.630-2.52g/L glycerol initially led to hydrogen production, followed by methane production a few days later, which stabilized within 1week. In conclusion, adjustment of the crude glycerol concentration allows controllable conversion to value-added products for co-digestion. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The semi-dry processing of coffee generates significant amounts of coffee pulp and wastewater. This study evaluated the production of bioethanol and volatile compounds of eight yeast strains cultivated in a mixture of these residues. Hanseniaspora uvarum UFLA CAF76 showed the best fermentation performance; hence it was selected to evaluate different culture medium compositions and inoculum size. The best results were obtained with 12% w/v of coffee pulp, 1 g/L of yeast extract and 0.3 g/L of inoculum. Using these conditions, fermentation in 1 L of medium was carried out, achieving higher ethanol yield, productivity and efficiency with values of 0.48 g/g, 0.55 g/L h and 94.11% respectively. Twenty-one volatile compounds corresponding to higher alcohols, acetates, terpenes, aldehydes and volatile acids were identified by GC-FID. Such results indicate that coffee residues show an excellent potential as substrates for production of value-added compounds. H. uvarum demonstrated high fermentative capacity using these residues.

    2014-02-01

    Lipid and fatty acid metabolism has been well studied in model microbial organisms like Escherichia coli and Bacillus subtilis. The major precursor of fatty acid biosynthesis is also the major product of fatty acid degradation (β-oxidation), acetyl-CoA, which is a key metabolite for all organisms. Controlling carbon flux to fatty acid biosynthesis and from β-oxidation allows for the biosynthesis of natural products of biotechnological importance. Ralstonia eutropha can utilize acetyl-CoA from fatty acid metabolism to produce intracellular polyhydroxyalkanoate (PHA). R. eutropha can also be engineered to utilize fatty acid metabolism intermediates to produce different PHA precursors. Metabolism of lipids and fatty acids can be rerouted to convert carbon into other value-added compounds like biofuels. This review discusses the lipid and fatty acid metabolic pathways in R. eutropha and how they can be used to construct reagents for the biosynthesis of products of industrial importance. Specifically, how the use of lipids or fatty acids as the sole carbon source in R. eutropha cultures adds value to these biotechnological products will be discussed here.

    Full Text Available Background: Omega-3 type of fatty acids have been known to be essential for not only heart health but overall wellness. Value added eggs with higher concentrations of omega-3-fatty acids in eggs are not only a palatable and easily available source but also heart healthy. However, the high concentration of cholesterol in eggs has been restrictive towards its acceptance. Aim: To check the efficacy of enriched eggs containing omega-3 fatty acids on the lipid profile of healthy volunteers to assess and set the leads whether their high fat content would have any adverse effect. Methods and results: Omega-3 eggs specially developed by us were given to normal healthy volunteers for two weeks and lipid profiles analyzed. Lipid profile normalizing effect of triglycerides and cholesterol was pronounced in the subjects studied. Conclusion: Consumption of omega-3 egg despite its total high fat content has no adverse effect. On the contrary it is beneficial and heart healthy retaining its natural nutrient quality

    This test operations procedure (TOP) provides the current standard for planning and conducting tests to measure the permeation or penetration of swatches of materials by chemical agents such as distilled mustard (HD), or the nerve agents sarin (GB), or V-agent (VX). The swatches may be single or multi-layered, inert, sorptive or reactive. Swatches may be taken from candidate or standardized fabrics, in which case application of this TOP can provide relative ranking or screening information about the ability of the standardized and/or candidate materials to resist permeation or penetration by chemical agents. Swatches may also be taken from garments that are new, have been stored, or have been worn for various times under different conditions. Testing these material swatches using the procedures in the TOP can provide data to evaluate the effects of the different condition of wear. This TOP is not adequate for the assessment of the ability of an end item clothing made from any tested material to protect the wearer. The data obtained by these procedures cannot be correlated to field conditions. One or more of the test procedures given may be required in a detailed test plan (DTP).

  3. Analysis of the Relevance of Information Content of the Value Added Statement in the Brazilian Capital Markets

    Full Text Available The usefulness of financial statements depends, fundamentally, on the degree of relevance of the information they disclose to users. Thus, studies that measure the relevance of accounting information to the users of financial statements are of some importance. One line of research within this subject is in ascertaining the relevance and importance of accounting information for the capital markets: if a particular item of accounting information is minimally reflected in the price of a share, it is because this information has relevance, at least at a certain level of significance, for investors and analysts of the capital markets. This present study aims to analyze the relevance, in the Brazilian capital markets, of the information content of the Value Added Statement (or VAS - referred to in Brazil as the Demonstração do Valor Adicionado, or DVA. It analyzed the ratio between stock price and Wealth created per share (WCPS, using linear regressions, for the period 2005-2011, for non-financial listed companies included in Melhores & Maiores ('Biggest & Best', an annual listing published by Exame Magazine in Brazil. As a secondary objective, this article seeks to establish whether WCPS represents a better indication of a company's result than Net profit per share (in this study, referred to as NPPS. The empirical evidence that was found supports the concept that the VAS has relevant information content, because it shows a capacity to explain a variation in the share price of the companies studied. Additionally, the relationship between WCPS and the stock price was shown to be significant, even after the inclusion of the control variables Stockholders' equity per share (which we abbreviate in this study to SEPS and NPPS. Finally, the evidence found indicates that the market reacts more to WCPS (Wealth created per share than to NPPS. Thus, the results obtained give some indication that, for the Brazilian capital markets, WCPS may be a better proxy

  4. Food waste collection and recycling for value-added products: potential applications and challenges in Hong Kong.

    About 3600 tonnes food waste are discarded in the landfills in Hong Kong daily. It is expected that the three strategic landfills in Hong Kong will be exhausted by 2020. In consideration of the food waste management environment and community needs in Hong Kong, as well as with reference to the food waste management systems in cities such as Linköping in Sweden and Oslo in Norway, a framework of food waste separation, collection, and recycling for food waste valorization is proposed in this paper. Food waste can be packed in an optic bag (i.e., a bag in green color), while the residual municipal solid waste (MSW) can be packed in a common plastic bag. All the wastes are then sent to the refuse transfer stations, in which food waste is separated from the residual MSW using an optic sensor. On the one hand, the sorted food waste can be converted into valuable materials (e.g., compost, swine feed, fish feed). On the other hand, the sorted food waste can be sent to the proposed Organic Waste Treatment Facilities and sewage treatment works for producing biogas. The biogas can be recovered to produce electricity and city gas (i.e., heating fuel for cooking purpose). Due to the challenges faced by the value-added products in Hong Kong, the biogas is recommended to be upgraded as a biogas fuel for vehicle use. Hopefully, the proposed framework will provide a simple and effective approach to food waste separation at source and promote sustainable use of waste to resource in Hong Kong.

    We examined whether schools achieving better than expected educational outcomes for their students influence the risk of drug use and delinquency among urban, racial/ethnic minority youth. Adolescents (n = 2,621), who were primarily African American and Hispanic and enrolled in Chicago public schools (n = 61), completed surveys in 6th (aged 12) and 8th (aged 14) grades. Value-added education was derived from standardized residuals of regression equations predicting school-level academic achievement and attendance from students' sociodemographic profiles and defined as having higher academic achievement and attendance than that expected given the sociodemographic profile of the schools' student composition. Multilevel logistic regression estimated the effects of value-added education on students' drug use and delinquency. After considering initial risk behavior, value-added education was associated with lower incidence of alcohol, cigarette and marijuana use; stealing; and participating in a group-against-group fight. Significant beneficial effects of value-added education remained for cigarette and marijuana use, stealing and participating in a group-against-group fight after adjustment for individual- and school-level covariates. Alcohol use (past month and heavy episodic) showed marginally significant trends in the hypothesized direction after these adjustments. Inner-city schools may break the links between social disadvantage, drug use and delinquency. Identifying the processes related to value-added education in order to improve school environments is warranted given the high costs associated with individual-level interventions.

    Nakagawa, Takashi

    2018-03-01

    I developed a combined model of the thermal and chemical evolution of the Earth's core and investigated its influence on a thermochemically stable region beneath the core-mantle boundary (CMB). The chemical effects of the growing stable region are caused by the equilibrium chemical reaction between silicate and the metallic core. The thermal effects can be characterized by the growth of the sub-isentropic shell, which may have a rapid growth rate compared to that of the chemically stable region. When the present-day CMB heat flow was varied, the origin of the stable region changed from chemical to thermochemical to purely thermal because the rapid growth of the sub-isentropic shell can replace the chemically stable region. Physically reasonable values of the present-day CMB heat flow that can maintain the geodynamo action over 4 billion years should be between 8 and 11 TW. To constrain the thickness of the thermochemically stable region beneath the CMB, the chemical diffusivity is important and should be ∼O(10-8) m2/s to obtain a thickness of the thermochemically stable region beneath the CMB consistent with that inferred from geomagnetic secular variations (140 km). However, the strength of the stable region found in this study is too high to be consistent with the constraint on the stability of the stable region inferred from geomagnetic secular variations.

    2018-03-01

    In the era of value-based medicine, it will become increasingly important for radiologists to provide metrics that demonstrate their value beyond clinical productivity. In this article the authors describe their institution's development of an easy-to-use system for tracking value-added but non-relative value unit (RVU)-based activities. Metrix Matrix is an efficient cloud-based system for tracking value-added work. A password-protected home page contains links to web-based forms created using Google Forms, with collected data populating Google Sheets spreadsheets. Value-added work metrics selected for tracking included interdisciplinary conferences, hospital committee meetings, consulting on nonbilled outside studies, and practice-based quality improvement. Over a period of 4 months, value-added work data were collected for all clinical attending faculty members in a university-based radiology department (n = 39). Time required for data entry was analyzed for 2 faculty members over the same time period. Thirty-nine faculty members (equivalent to 36.4 full-time equivalents) reported a total of 1,223.5 hours of value-added work time (VAWT). A formula was used to calculate "value-added RVUs" (vRVUs) from VAWT. VAWT amounted to 5,793.6 vRVUs or 6.0% of total work performed (vRVUs plus work RVUs [wRVUs]). Were vRVUs considered equivalent to wRVUs for staffing purposes, this would require an additional 2.3 full-time equivalents, on the basis of average wRVU calculations. Mean data entry time was 56.1 seconds per day per faculty member. As health care reimbursement evolves with an emphasis on value-based medicine, it is imperative that radiologists demonstrate the value they add to patient care beyond wRVUs. This free and easy-to-use cloud-based system allows the efficient quantification of value-added work activities. Copyright © 2017 American College of Radiology. Published by Elsevier Inc.

    Full Text Available Root rot in cocoyam (Colocasia esculenta, Xanthosoma saggitifolium is caused by various pathogens, among which are: F. sulfureum, F. solani, F. chlamydosporum, F. oxysporum, S. rolfsii, R. solani, Phoma sp.Diplodia sp., R. nigricans. Within the principal fungicides registered in Cuba for seed protection are mancozeb,captan, benomyl, tiran, carboxin + tiran, thiabendazole, guazatine and propamocarb among others, which are used against many fungi pathogen genera. In order to study the “in vitro ” chemical control effectiveness of Celest 0.25 FS and Celest Top 312 in combating these pathogens, this study was performed in the Phytopathology laboratory from the Research Institute of Tropical Root and Tuber Crops (INIVIT. The Potato Dextrose Agar (PDA medium that was poisoned at doses of 180, 300 and 500ppm with fungicides Celest 0.25 FS and Celest Top FS 312 was used. The fungal pathogens studied were: Fusarium sulfureum, Sclerotium rolfsii, Rhizoctonia solani and Phoma sp. Measurements were made on mycelial growth after 48, 72, 96, 120 and 144 hours alter planting. The best results in the application of Celest 0.25 FS is obtained with the dose of 500 ppm. Doses of 180 and 300 ppm exert little effect on these pathogens. Top Celest doses 312 FS (300 and 500 ppm, are very effective on “in vitro” control of fungal species tested, showing a limited radial 0.9 and 0.4 cm respectively as average.

  18. Greenhouse gas emissions per unit of value added (“GEVA”) — A corporate guide to voluntary climate action

    Randers, Jorgen

    2012-01-01

    How much must I reduce my greenhouse gas (GHG) emissions if I want to do my fair share to contribute towards the global effort to keep global warming below a 2 °C rise in average temperature over preindustrial times? This paper suggests an answer for nations and corporations that want to move ahead of legislation on a voluntary basis. If all nations reduce their “GHG emissions per unit of GDP” by 5% per year, global GHG emissions will be 50% lower in 2050 than in 2010 as long as the global economy continues to grow at its historical rate of 3.5% per year. The suggested 5% per year decline can be translated into a corporate resolution to reduce corporate “GHG emissions per unit of value added” (GEVA) by 5% per year. If all corporations cut their GEVA by 5% per year, the same global result will be achieved. The suggested 5% per year decline can be used as a guideline for responsible action on a voluntary basis. The guideline is unlikely to be made mandatory soon, but compulsory publication of the necessary emissions and productivity data by nations and corporations could help civil society highlight top performers. - Highlights: ► The world needs to reduce GHG emissions by 50% by 2050. ► Is achievable if nations reduce “GHG emissions per unit of GDP” by 5%/year. ► Or if corporations reduce “GHG emissions per unit of value added” by 5 %/year. ► Corporations that reduce GEVA by 5%/year can be said to do their fair share. ► Mandatory reporting of corporate GEVA could motivate such reductions.

  19. Employment and taxes in Latin America: An empirical study of the effects of payroll, corporate income and value-added taxes on labor outcomes

    Directory of Open Access Journals (Sweden)

    Eduardo Lora

    2016-01-01

    Full Text Available This paper empirically explores the effects of payroll taxes, value-added taxes and corporate income taxes on a variety of labor market outcomes such as participation, employment, informality, and wages. The results are based on nationallevel data of labor variables for 15 Latin American countries, and indicate that the effects of each tax are markedly different and may depend on several aspects of labor and tax institutions. Payroll taxes reduce employment and increase labor costs when their benefits are not valued by workers, but otherwise may increase labor participation and not raise labor costs. Value-added taxes increase informality and reduce skilled labor demand. In contrast, corporate income taxes may help reduce informality, especially among low education workers, but when tax enforcement capabilities are strong they may reduce labor participation and employment of medium- and high-education workers.

    Bioelectrochemical systems (BES) can accomplish simultaneous wastewater treatment and resource recovery via interactions between microbes and electrodes. Often deemed as "energy efficient" technologies, BES have not been well evaluated for their energy performance, such as energy production and consumption. In this work, we have conducted a review and analysis of energy balance in BES with parameters like normalized energy recovery, specific energy consumption, and net energy production. Several BES representatives based on their functions were selected for analysis, including direct electricity generation in microbial fuel cells, hydrogen production in microbial electrolysis cells, nitrogen recovery in BES, chemical production in microbial electrosynthesis cells, and desalination in microbial desalination cells. Energy performance was normalized to water volume (kWh m -3 ), organic removal (kWh kg COD -1 ), nitrogen recovery (kWh kg N -1 ), chemical production (kWh kg -1 ), or removed salt during desalination (kWh kg -1 ). The key operating factors such as pumping system (recirculation/feeding pumps) and external power supply were discussed for their effects on energy performance. This is an in-depth analysis of energy performance of various BES and expected to encourage more thinking, analysis, and presentation of energy data towards appropriate research and development of BES technology for resource recovery from wastewater.

    Full Text Available The domain of value-added tax has been already fully harmonized. Its regulation dwells on the Council Directive 2006/112/EC on the common system of value-added tax, and all member countries of the European Union are obliged to provide for the implementation of this Directive into their national legislations similarly as the Czech Republic, which entered the European Union on 1 May 2004. The Act no. 235/2004 Coll. on the value-added tax as amended (hereinafter „value-added tax law“ should be therefore in line with the Directive. In reality however, some issues in the VAT law have not been fully harmonized yet. One of these issues is for example the application of a special routine for travel services according to §89 of the VAT law, which is in essential contradiction with the Directive in question, the controversial point being definition of the person of customer whom the Directive understands in a different way than the VAT law. Thus, the characterization of the problem based on the Czech and EU legislations with respect to jurisdiction of the Court of Justice of the European Community forms a framework of the paper. Based on a comparative analysis of the application of special and ordinary routines in providing travel services to the customer by the taxpayer, tax incidence in his assessment base is determined. At the same time, the paper also includes a proposal for the change of the definition of customer in the VAT law so that the application of the given routine is fully in line with the EU Directive.

    Man-made endocrine-disrupting chemicals (EDCs) range across all continents and oceans. Some geographic areas are potentially more threatened than others: one of these is the Mediterranean Sea. Levels of some xenobiotics are much higher here than in other seas and oceans. In this paper we review the final results of a project supported by the Italian Ministry of the Environment, in which the hypothesis that Mediterranean top predator species (such as large pelagic fish and marine mammals) are potentially at risk due to EDCs was investigated. We illustrate the need to develop and apply sensitive methodological tools, such as biomarkers (Vitellogenin, Zona Radiata proteins and CYP1A activities) for evaluation of toxicological risk in large pelagic fish top predators (Swordfish (Xiphias gladius), Bluefin Tuna (Thunnus thynnus thynnus)) and nondestructive biomarkers (CYP1A activities and fibroblast cell culture in skin biopsy), for the hazard assessment of threatened marine mammals species (Striped Dolphin, (Stenella coeruleoalba), Bottlenose Dolphin (Tursiops truncatus), Common Dolphin (Delphinus delphis) and Fin Whale (Balaenoptera physalus))exposed to EDCs. Differential gender susceptibility to EDCs is also explored both in large pelagic fish and in cetaceans. In cetaceans, male specimens showed higher cytochrome P450 induction (BPMO in skyn biopsies, CYP2B in fibroblasts cell cultures) by xenobiotics with respect to females

    This report was prepared in response to the U.S. Department of Energy Fuel Cell Technologies Office Congressional Appropriation language to support research on carbon-free production of hydrogen using new chemical processes that utilize natural gas to produce solid carbon and hydrogen. The U.S. produces 9-10 million tons of hydrogen annually with more than 95% of the hydrogen produced by steam-methane reforming (SMR) of natural gas. SMR is attractive because of its high hydrogen yield; but it also converts the carbon to carbon dioxide. Non-oxidative thermal decomposition of methane to carbon and hydrogen is an alternative to SMR and produces CO2-free hydrogen. The produced carbon can be sold as a co-product, thus providing economic credit that reduces the delivered net cost of hydrogen. The combination of producing hydrogen with potentially valuable carbon byproducts has market value in that this allows greater flexibility to match the market prices of hydrogen and carbon. That is, the higher value product can subsidize the other in pricing decisions. In this report we highlight the relevant technologies reported in the literature—primarily thermochemical and plasma conversion processes—and recent research progress and commercial activities. Longstanding technical challenges include the high energetic requirements (e.g., high temperatures and/or electricity requirements) necessary for methane activation and, for some catalytic processes, the separation of solid carbon product from the spent catalyst. We assess current and new carbon product markets that could be served given technological advances, and we discuss technical barriers and potential areas of research to address these needs. We provide preliminary economic analysis for these processes and compare to other emerging (e.g., electrolysis) and conventional (e.g., SMR) processes for hydrogen production. The overarching conclusion of this study is that the cost of hydrogen can be potentially

    2007-01-01

    The introduction of smart card technology has ushered in a new era of electronic medical information systems. Taiwan's Bureau of National Health Insurance (BNHI) implemented the National Health Insurance (NHI) smart card project in 2004. The purpose of the project was to replace all paper cards with one smart card. The NHI medical network now provides three kinds of services. In this paper, we illustrate the status of the NHI smart card system in Taiwan and propose three kinds of value-added applications for the medical network, which are electronic exchange of medical information, retrieval of personal medical records and medical e-learning for future development of health information systems.

    This study focuses on the valorisation of crude glycerol and sunflower meal (SFM) from conventional biodiesel production plants for the separation of value-added co-products (antioxidant-rich extracts and protein isolate) and for enhancing biodiesel production through microbial oil synthesis. Microbial oil production was evaluated using three oleaginous yeast strains (Rhodosporidium toruloides, Lipomyces starkeyi and Cryptococcus curvatus) cultivated on crude glycerol and nutrient-rich hydrolysates derived from either whole SFM or SFM fractions that remained after separation of value-added co-products. Fed-batch bioreactor cultures with R. toruloides led to the production of 37.4gL(-1) of total dry weight with a microbial oil content of 51.3% (ww(-1)) when a biorefinery concept based on SFM fractionation was employed. The estimated biodiesel properties conformed with the limits set by the EN 14214 and ASTM D 6751 standards. The estimated cold filter plugging point (7.3-8.6°C) of the lipids produced by R. toruloides is closer to that of biodiesel derived from palm oil. Copyright © 2015 Elsevier Ltd. All rights reserved.

    2014-04-01

    Full Text Available The purpose of this study is to understand which bibliographic data are the core elements of the user’s queries? What users’ viewpoints about resource descriptions using different metadata standards? What kinds of value-added items are the users’ favorite when they conduct a bibliographic search? What are users’ viewpoints about bibliographic records integrated with the Digital Archival and Institutional Repository resources through metadata interoperability methods? This research adopted experiments, observation and interviews. The sample subjects are drawn from 14 students of The Graduate Institute of Library and Information Science and College of Agriculture and Natural Resources. First of all, the researcher displayed the bibliographic records using original MARC from the library. Secondly, users compared the images of OPAC from the library with the format of DC and MODS transformed through the MarcEdit software. Additionally, the researcher conducted interviews to understand users’ viewpoints about using three metadata schemas to describe the same book. Finally, the researcher asked the degree of users’ satisfaction about using bibliographic records alone and bibliographic records integrated with the Digital Archival and Institutional Repository resources. The findings suggest that libraries could provide more value-added and comprehensive services of bibliographic records and information retrieval, in order for all kinds of resources to be fully utilized, which helps to meet the users’ information needs.

  5. Integrated microbial processes for biofuels and high value-added products: the way to improve the cost effectiveness of biofuel production.

    Science.gov (United States)

    da Silva, Teresa Lopes; Gouveia, Luísa; Reis, Alberto

    2014-02-01

    The production of microbial biofuels is currently under investigation, as they are alternative sources to fossil fuels, which are diminishing and their use has a negative impact on the environment. However, so far, biofuels derived from microbes are not economically competitive. One way to overcome this bottleneck is the use of microorganisms to transform substrates into biofuels and high value-added products, and simultaneously taking advantage of the various microbial biomass components to produce other products of interest, as an integrated process. In this way, it is possible to maximize the economic value of the whole process, with the desired reduction of the waste streams produced. It is expected that this integrated system makes the biofuel production economically sustainable and competitive in the near future. This review describes the investigation on integrated microbial processes (based on bacteria, yeast, and microalgal cultivations) that have been experimentally developed, highlighting the importance of this approach as a way to optimize microbial biofuel production process.

  6. Value-Added Clinical Systems Learning Roles for Medical Students That Transform Education and Health: A Guide for Building Partnerships Between Medical Schools and Health Systems.

    Gonzalo, Jed D; Lucey, Catherine; Wolpaw, Terry; Chang, Anna

    2017-05-01

    To ensure physician readiness for practice and leadership in changing health systems, an emerging three-pillar framework for undergraduate medical education integrates the biomedical and clinical sciences with health systems science, which includes population health, health care policy, and interprofessional teamwork. However, the partnerships between medical schools and health systems that are commonplace today use health systems as a substrate for learning. Educators need to transform the relationship between medical schools and health systems. One opportunity is the design of authentic workplace roles for medical students to add relevance to medical education and patient care. Based on the experiences at two U.S. medical schools, the authors describe principles and strategies for meaningful medical school-health system partnerships to engage students in value-added clinical systems learning roles. In 2013, the schools began large-scale efforts to develop novel required longitudinal, authentic health systems science curricula in classrooms and workplaces for all first-year students. In designing the new medical school-health system partnerships, the authors combined two models in an intersecting manner-Kotter's change management and Kern's curriculum development steps. Mapped to this framework, they recommend strategies for building mutually beneficial medical school-health system partnerships, including developing a shared vision and strategy and identifying learning goals and objectives; empowering broad-based action and overcoming barriers in implementation; and generating short-term wins in implementation. Applying this framework can lead to value-added clinical systems learning roles for students, meaningful medical school-health system partnerships, and a generation of future physicians prepared to lead health systems change.

    2014-08-01

    Full Text Available An integrated process has been developed for a wheat straw biorefinery. In this process, wheat straw was pretreated by soaking in aqueous ammonia (SAA, which extensively removed lignin but preserved high percentages of the carbohydrate fractions for subsequent bioconversion. The pretreatment conditions included 15 wt% NH4OH, 1:10 solid:liquid ratio, 65 oC and 15 hours. Under these conditions, 48% of the original lignin was removed, whereas 98%, 83% and 78% of the original glucan, xylan, and arabinan, respectively, were preserved. The pretreated material was subsequently hydrolyzed with a commercial hemicellulase to produce a solution rich in xylose and low in glucose plus a cellulose-enriched solid residue. The xylose-rich solution then was used for production of value-added products. Xylitol and astaxanthin were selected to demonstrate the fermentability of the xylose-rich hydrolysate. Candida mogii and Phaffia rhodozyma were used for xylitol and astaxanthin fermentation, respectively. The cellulose-enriched residue obtained after the enzymatic hydrolysis of the pretreated straw was used for ethanol production in a fed-batch simultaneous saccharification and fermentation (SSF process. In this process, a commercial cellulase was used for hydrolysis of the glucan in the residue and Saccharomyces cerevisiae, which is the most efficient commercial ethanol-producing organism, was used for ethanol production. Final ethanol concentration of 57 g/l was obtained at 27 wt% total solid loading.

    Full Text Available Olive (Olea europaea L. oil processing produces significant amount of waste that can be utilized for the production of high value-added ingredients for various industrial applications. In this work, the effects of temperature on drying kinetics and quality indexes of the olive-waste cake during convective dehydration (40-90 °C were investigated. Results on effective moisture diffusivity, physicochemical parameters, fatty acid profile, total phenolic, flavonoid, and flavanol contents as well as antioxidant capacity are also reported. Most of the fatty acids increased their content with respect to control sample with a temperature increase, i.e. oleic and linoleic acids increased 48% and 43% at 70 and 40 °C, respectively. Total flavanol content increased with temperature (48-62 mg catechin equivalents [CTE] 100 g-1 DM except for 80 °C. Total phenolic and total flavonoid contents were highly correlated to antioxidant capacity (0.923 < r < 0.992, except for 70 and 80 °C, the rest of the samples maintained their initial antioxidant capacity by ORAC analysis. Thus, these parameters show that dried olive-waste cake has a high bioactive compounds with potential use as additives for the food or other industries.

    To improve pharmaceutical care delivery in Malaysia, the Ministry of Health (MOH) had introduced the concept of value added services (VAS). Despite its reported convenience and advantages, VAS utilization rate is low in the country. The study aims to explore patients' understanding, beliefs and expectations towards VAS in Malaysia using the theory of planned behaviour (TPB) as the theoretical model. A qualitative methodology was used whereby face-to-face interviews were conducted with 12 patients who collected partial medicine supplies from government pharmacies. Participants were recruited using purposive and snowball sampling method in the state of Negeri Sembilan, Malaysia. Interviews were audio-recorded. Verbatim transcription and thematic content analysis were performed on the data. Thematic content analysis yielded five major themes: (i) attitudes towards using VAS, (ii) subjective norms, (iii) perceived behavioural control, (iv) lack of knowledge and understanding of VAS and (v) expectations towards VAS. The interviews explored and informed new information about salient beliefs towards pharmacy VAS. The findings suggest that VAS is still in its infancy and a more robust and effective advertising and marketing campaign is needed to boost the adoption rate. Behavioural attitudes, subjective norms and perceived control elements were discussed and serve as important variables of interest in future study. Expectations towards VAS serve as an important guideline to further improve patient-oriented services. © 2015 The Authors. Health Expectations Published by John Wiley & Sons Ltd.

    2012-09-01

    Full Text Available The effects of either cooking temperature (45, 80, and 100 °C or inclusion of seed particles on the dynamic-mechanical and sensorial properties of value-added Crimson seedless, Black Pearl, or Baresana grape-based smoothies were studied. The inclusion of seed particles resulted in significant increases of the phenolic content, both in Black Pearl and Baresana, but it did not affect in a negative way the sensorial characteristics of smoothies whereas it caused an increase of the viscoelastic behavior of Black Pearl and a slight decrease in Baresana grape-based smoothies. In particular, the investigated rheological parameters were the loss and storage modulus. Moreover, the loss tangent value (the ratio between loss and storage modulus remained unchanged, indicating a pseudoplastic behavior of all samples, independent on the process conditions. The smoothies produced from Crimson grapes at the intermediate temperature (80 °C showed sensorial and rheological characteristics similar to those manufactured at 45 °C and better than those manufactured at 100 °C.

    This study compared the accuracy and precision of four value-added glucose meters. Finger stick glucose measurements in diabetes patients were performed using the Abbott Diabetes Care (Alameda, CA) Optium, Diagnostic Devices, Inc. (Miami, FL) DDI Prodigy, Home Diagnostics, Inc. (Fort Lauderdale, FL) HDI True Track Smart System, and Arkray, USA (Minneapolis, MN) HypoGuard Assure Pro. Finger glucose measurements were compared with laboratory reference results. Accuracy was assessed by a Clarke error grid analysis (EGA), a Parkes EGA, and within 5%, 10%, 15%, and 20% of the laboratory value criteria (chi2 analysis). Meter precision was determined by calculating absolute mean differences in glucose values between duplicate samples (Kruskal-Wallis test). Finger sticks were obtained from 125 diabetes patients, of which 90.4% were Caucasian, 51.2% were female, 83.2% had type 2 diabetes, and average age of 59 years (SD 14 years). Mean venipuncture blood glucose was 151 mg/dL (SD +/-65 mg/dL; range, 58-474 mg/dL). Clinical accuracy by Clarke EGA was demonstrated in 94% of Optium, 82% of Prodigy, 61% of True Track, and 77% of the Assure Pro samples (P meters. Within 5% accuracy was achieved in 34%, 24%, 29%, and 13%, respectively (P meter systems. The HDI True Track was significantly less precise than the other meter systems. The Abbott Optium was significantly more accurate than the other meter systems, whereas the HDI True Track was significantly less accurate and less precise compared to the other meter systems.

    Out-of-pocket healthcare expense represents a challenge for health systems for it constitutes a barrier to health care, impacting the equality of access to healthcare systems, something particularly important in the Chilean health system. In this context, the Government recently raised the possibility of incorporating a tax on imaging tests, creating debate over its potential consequences. To explore the impact on household out-of-pocket healthcare expense by the implementation of a value added tax to imaging tests in Chile. Cross-sectional study using data of household expenditures from the VII Household Budget Survey. Out-of-pocket healthcare expense and catastrophic household expenses are calculated comparing two scenarios, with and without the inclusion of the proposed tax. Analyses are presented by income deciles to explore the differential equality impact. 42.8% of diagnostic test expense on household corresponds to imaging studies. Under a scenario of tax implementation, a relative increase of 1.1% of out-of-pocket expenses and 2.2% of catastrophic household expenses is observed. The groups that suffer the greatest impact are those with lower income levels, concentrating in the first fifth deciles. We conclude that, although the increase in the average out-of- pocket spending is moderate, this policy may involve a significant increase in the catastrophic expense of the population with the lowest incomes, thereby increasing health inequalities. Considering the challenges of health system financing in Chile, it appears that such fiscal policy would only worsen the possibility of moving towards lower levels of out-of-pocket of household expenses.

    The objective of this study was to examine the ethanol yield potential of three barley varieties (Xena, Bold, and Fibar) in comparison to two benchmarks, corn and wheat. Very high gravity (VHG; 30% solids) fermentations using both conventional and Stargen 001 enzymes for starch hydrolysis were carried out as simultaneous saccharification and fermentation. The grains and their corresponding dried distiller's grain with solubles (DDGS) were also analyzed for nutritional and value-added characteristics. A VHG traditional fermentation approach utilizing jet-cooking fermentation revealed that both dehulled Bold and Xena barley produced ethanol concentrations higher than that produced by wheat (12.3, 12.2, and 11.9%, respectively) but lower than that produced by corn (13.8%). VHG-modified Stargen-based fermentation of dehulled Bold barley demonstrated comparable performance (14.3% ethanol) relative to that of corn (14.5%) and wheat (13.3%). Several important components were found to survive fermentation and were concentrated in DDGS. The highest yield of phenolics was detected in the DDGS (modified Stargen 001, 20% solids) of Xena (14.6 mg of gallic acid/g) and Bold (15.0 mg of gallic acid/g) when the hull was not removed before fermentation. The highest concentration of sterols in DDGS from barley was found in Xena (3.9 mg/g) when the hull was included. The DDGS recovered from corn had the highest concentration of fatty acids (72.6 and 77.5 mg/g). The DDGS recovered from VHG jet-cooking fermentations of Fibar, dehulled Bold, and corn demonstrated similar levels of tocopherols and tocotrienols. Corn DDGS was highest in crude fat but was lowest in crude protein and in vitro energy digestibility. Wheat DDGS was highest in crude protein content, similar to previous studies. The barley DDGS was the highest in in vitro energy digestibility.

    2013-01-01

    Full Text Available Aims: Improper disposal of domestic wastes, such as waste cooking oil (WCO, contributes to the deterioration of the environment and may lead to health problems. In this study, we evaluated the potential of plant-based WCO as a carbon source for the commercial biosynthesis of the bio-plastics, poly(3-hydroxybutyrate and poly(3-hydroxybutyrate-co-3-hydroxyhexanoate. The consumption of WCO for this purpose would mitigate their pollution of the environment at the same time.Methodology and Results: WCO collected from several cafeterias in USM was tested as the carbon source for polyhydroxyalkanoates (PHA production. A selection of suitable nitrogen source was first conducted in order to obtain an acceptable number of dry cell weight (DCW and PHA content. Urea was found to be a suitable nitrogen source for the two bacterial strains used in our study, Cupriavidus necator H16 and its transformed mutant, C. necator PHB¯4 harboring the PHA synthase gene of Aeromonas caviae (PHB¯4/pBBREE32d13. With WCO as the sole carbon source, C. necator H16 yielded a relatively good dry cell weight (DCW=25.4 g/L, with 71 wt% poly(3-hydroxybutyrate P(3HBcontent. In comparison, the DCW obtained with fresh cooking oil (FCO was 24.8 g/L. The production of poly(3 hydroxybutyrate-co-3- hydroxyhexanoate [P(3HB-co-3HHx] from WCO by the transformant C. necator PHB¯4 was comparable, yielding a DCW of 22.3 g/L and P(3HB-co-3HHx content of 85 wt%. Lipase activities for both bacterial strains reached a maximum after 72 h of cultivation when time profile was conducted. Conclusion, significance and impact of study: The use of WCO as a carbon source in the biosynthesis of the bioplastic, PHA, turns a polluting domestic waste into a value-added biodegradable product. This renewable source material can thus be exploited for the low cost production of PHA.

    For the first time, ZrO2 dielectric deposition on pristine monolayer MoS2 by atomic layer deposition (ALD) is demonstrated and ZrO2/MoS2 top-gate MOSFETs have been fabricated. ALD ZrO2 overcoat, like other high-k oxides such as HfO2 and Al2O3, was shown to enhance the MoS2 channel mobility. As a result, an on/off current ratio of over 107, a subthreshold slope of 276 mV dec-1, and a field-effect electron mobility of 12.1 cm2 V-1 s-1 have been achieved. The maximum drain current of the MOSFET with a top-gate length of 4 μm and a source/drain spacing of 9 μm is measured to be 1.4 μA μm-1 at V DS = 5 V. The gate leakage current is below 10-2 A cm-2 under a gate bias of 10 V. A high dielectric breakdown field of 4.9 MV cm-1 is obtained. Gate hysteresis and frequency-dependent capacitance-voltage measurements were also performed to characterize the ZrO2/MoS2 interface quality, which yielded an interface state density of ˜3 × 1012 cm-2 eV-1.

    2011-01-01

    Growing demand from clients waiting to access vital services in a healthcare sector under economic constraint, coupled with the pressure for ongoing improvement within a multi-faceted organization, can have a significant impact on the front-line staff, who are essential to the successful implementation of any quality improvement initiative. The Lean methodology is a management system for continuous improvement based on the Toyota Production System; it focuses on two main themes: respect for people and the elimination of waste or non-value-added activities. Within the Lean process, value-added is used to describe any activity that contributes directly to satisfying the needs of the client, and non-value-added refers to any activity that takes time, space or resources but does not contribute directly to satisfying client needs. Through the revision of existing models of service delivery, the authors' organization has made an impact on increasing access to care and has supported successful engagement of staff in the process, while ensuring that the focus remains on the central needs of clients and families accessing services. While the performance metrics continue to exhibit respectable results for this strategic priority, further gains are expected over the next 18-24 months.

    The top-down fabrication of an in-plane nanowire (NW) GaAs metal-oxide-semiconductor field-effect transistor (MOSFET) with a trigate oxide implemented by liquid-phase chemical-enhanced oxidation (LPCEO) is reported. A 2 μm long channel having an effective cross section ˜70 × 220 nm2 is directly fabricated into an epitaxial n +-GaAs layer. This in-plane NW structure is achieved by focused ion beam (FIB) milling and hydrolyzation oxidation resulting in electronic isolation from the substrate through a semiconductor-on-insulator structure with an n +-GaAs/Al2O3 layer stack. The channel is epitaxially connected to the μm-scale source and drain within a single layer for a planar MOSFET to avoid any issues of ohmic contact and LPCEO to the NW. To fabricate a MOSFET, the top and the two sidewalls of the in-plane NW are oxidized by LPCEO to relieve the surface damage from FIB as well as to transform these surfaces to a ˜15 nm thick gate oxide. This trigate device has threshold voltage ˜0.14 V and peak transconductance ˜35 μS μm-1 with a subthreshold swing ˜150 mV/decade and on/off ratio of drain current ˜103, comparable to the performance of bottom-up NW devices.

    Full Text Available The impact of agricultural management practices on the quality of grain was evaluated in wheat (Triticum aestivum L. BRS Tangará from the South Central region of Paraná State (Ponta Grossa in the crop years of 2010 and 2011. The field trial was carried out in succession with soybean (2010 and corn (2011. The treatments included inoculation of seeds with Azospirillum brasilense and increasing levels of nitrogen application in top dressing (0, 30, 60, 90 and 120 kg ha-1. The experimental design was in randomized block, factorial 2 x 5 (inoculation x N levels, with four replications. The parameters evaluated were water activity, moisture, protein, and grain contamination by deoxynivalenol (DON. The data were subjected to analysis of variance, comparison of means by Tukey’s test (p<0.05 and regression for nitrogen levels. The inoculation of seeds with A. brasilense increased the protein content in grain in 2010 (+1.6%; 16.9 g 100g-1 and 2011 (+1.7%, 15.7 g 100g-1, independently of the nitrogen level (p<0.01. Levels of nitrogen in 2010 presented a positive linear response with protein content, increasing by 14.2% using non-inoculated seeds (p<0.01, R2=0.955 and 14.4% for those inoculated with A. brasilense (p<0.01, R2=0.906. However, in 2011 a quadratic response was observed between nitrogen levels and protein content (p<0.01, R2=0.99, with stabilization or reduction in protein content using high levels of nitrogen (?120 kg ha-1. The contamination by DON was greater using high levels of nitrogen (3574 ?g kg-1, 120 kg ha-1; non-inoculated seeds in 2011, with a quadratic response between nitrogen levels and contamination of grains (p<0.05, R2=0.772. Furthermore, 37.5% of the samples presented contamination by DON higher than the maximum tolerated limit established by Brazilian legislation (2000 ?g kg-1; whole-wheat grain. The data demonstrates that proper management of nitrogen enhances intrinsic effects arising from plant breeding.

    The authors present the latest results about top physics obtained by the CDF experiment at the Fermilab Tevatron collider. The data sample used for these analysis (about 110 pb{sup{minus}1}) represents almost the entire statistics collected by CDF during four years (1992--95) of data taking. This large data size has allowed detailed studies of top production and decay properties. The results discussed here include the determination of the top quark mass, the measurement of the production cross section, the study of the kinematics of the top events and a look at top decays.

    The U.S. Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) Climate Research Facility Raman lidars (RLs) are semi-autonomous, land-based, laser remote sensing systems that provide height- and time-resolved measurements of water vapor mixing ratio, temperature, aerosol backscatter, extinction, and linear depolarization ratio from about 200 m to greater than 10 km AGL. These systems transmit at a wavelength of 355 nm with 300 mJ, ~5 ns pulses, and a pulse repetition frequency of 30 Hz. The receiver incorporates nine detection channels, including two water vapor channels at 408 nm, two nitrogen channels at 387 nm, three elastic channels, and two rotational Raman channels for temperature profiling at 354 and 353 nm. Figure 1 illustrates the layout of the ARM RL receiver system. Backscattered light from the atmosphere enters the telescope and is directed into the receiver system (i.e., aft optics). This signal is then split between a narrow-field-of-view radiometer (NFOV) path (blue) and a wide-field-of-view zenith radiometer (WFOV) path (red). The WFOV (2 mrad) path contains three channels (water vapor, nitrogen, and unpolarized elastic), and the NFOV (0.3 mrad) path contains six channels (water vapor, nitrogen, parallel and perpendicular elastic, and two rotational Raman). All nine detection channels use Electron Tubes 9954B photomultiplier tubes (PMTs). The signals from each of the nine PMTs are acquired using transient data recorders from Licel GbR (Berlin, Germany). The Licel data recorders provide simultaneous measurements of both analog photomultiplier current and photon counts at height resolution of 7.5 m and a time resolution of 10 s. The analog signal provides good linearity in the strong signal regime, but poor sensitivity at low signal levels. Conversely, the photo counting signal provides good sensitivity in the weak signal regime, but is strongly nonlinear at higher signal levels. The advantage in recording both signals is that they can be combined (or merged) into a single signal with improved dynamic range. The process of combining the analog and photon counting data has become known as “gluing” (Whiteman et al., 2006).

    Wind speed and direction, together with pressure, temperature, and relative humidity, are the most fundamental atmospheric state parameters. Accurate measurement of these parameters is crucial for numerical weather prediction. Vertically resolved wind measurements in the atmospheric boundary layer are particularly important for modeling pollutant and aerosol transport. Raw data from a scanning coherent Doppler lidar system can be processed to generate accurate height-resolved measurements of wind speed and direction in the atmospheric boundary layer.

    We report on top physics results using a 100 pb{sup -1} data sample of p{bar p} collisions at {radical}s = 1.8 TeV collected with the Collider Detector at Fermilab (CDF). We have identified top signals in a variety of decay channels, and used these channels to extract a measurement of the top mass and production cross section. A subset of the data (67 pb{sup -1}) is used to determine M{sub top} = 176 {+-} 8(stat) {+-} 10(syst) and {sigma}(tt) = 7.6 {sub -2.0}{sup +2.4} pb. We present studies of the kinematics of t{bar t} events and extract the first direct measurement of V{sub tb}. Finally, we indicate prospects for future study of top physics at the Tevatron.

  3. Top quark mass measurement

    Energy Technology Data Exchange (ETDEWEB)

    Maki, Tuula [Univ. of Helsinki (Finland)

    2008-03-18

    The top quark is the heaviest elementary particle. Its mass is one of the fundamental parameters of the standard model of particle physics, and an important input to precision electroweak tests. This thesis describes three measurements of the top-quark mass in the dilepton decay channel. The dilepton events have two neutrinos in the final state; neutrinos are weakly interacting particles that cannot be detected with a multipurpose experiment. Therefore, the signal of dilepton events consists of a large amount of missing energy and momentum carried off by the neutrinos. The top-quark mass is reconstructed for each event by assuming an additional constraint from a top mass independent distribution. Template distributions are constructed from simulated samples of signal and background events, and parametrized to form continuous probability density functions. The final top-quark mass is derived using a likelihood fit to compare the reconstructed top mass distribution from data to the parametrized templates. One of the analyses uses a novel technique to add top mass information from the observed number of events by including a cross-section-constraint in the likelihood function. All measurements use data samples collected by the CDF II detector.

    In this talk we summarize the top physics setup in the event generator WHIZARD with a main focus on lepton colliders. This includes full six-, eight- and ten-fermion processes, factorized processes and spin correlations. For lepton colliders, QCD NLO processes for top quark physics are available and discussed. A special focus is on the top-quark pair threshold, where a special implementation combines a non-relativistic effective field theory calculation augmented by a next-to-leading threshold logarithm resummation with a continuum relativistic fixed-order QCD NLO simulation.

    The top quark is the most massive fundamental particle observed so far, and the study of its properties is interesting for several reasons ranging from its possible special role in electroweak symmetry breaking to its sensitivity to physics beyond the Standard Model (SM). This article focuses on the latest top physics results from CDF based on 320-750 pb{sup -1} of p{bar p} collision data at {radical}s = 1.96 TeV. The t{bar t} cross section and the top mass have been measured in different decay channels and using different methods. They have also searched for massive t{bar t} resonances.

    A model is outlined, where the top quark gets a mass by a supersymmetric extension of the Higgs effect, eating a quark-gaugino. The GIM-violating phenomenology of a Q=2/3 vector-like quark, mixing with the standard up-type quarks, is described. The modifications of supersymmetry signals and the problem of giving masses to all other quarks and leptons, except the top, by radiative corrections are also briefly discussed.

  14. Using the Biodatamation(TM) strategy to learn introductory college biology: Value-added effects on selected students' conceptual understanding and conceptual integration of the processes of photosynthesis and cellular respiration

    Science.gov (United States)

    Reuter, Jewel Jurovich

    The purpose of this exploratory research was to study how students learn photosynthesis and cellular respiration and to determine the value added to the student's learning by each of the three technology-scaffolded learning strategy components (animated concept presentations and WebQuest-style activities, data collection, and student-constructed animations) of the BioDatamation(TM) (BDM) Program. BDM learning strategies utilized the Theory of Interacting Visual Fields(TM) (TIVF) (Reuter & Wandersee, 2002a, 2002b; 2003a, 2003b) which holds that meaningful knowledge is hierarchically constructed using the past, present, and future visual fields, with visual metacognitive components that are derived from the principles of Visual Behavior (Jones, 1995), Human Constructivist Theory (Mintzes & Wandersee, 1998a), and Visual Information Design Theory (Tufte, 1990, 1997, 2001). Student alternative conceptions of photosynthesis and cellular respiration were determined by the item analysis of 263,267 Biology Advanced Placement Examinations and were used to develop the BDM instructional strategy and interview questions. The subjects were 24 undergraduate students of high and low biology prior knowledge enrolled in an introductory-level General Biology course at a major research university in the Deep South. Fifteen participants received BDM instruction which included original and innovative learning materials and laboratories in 6 phases; 8 of the 15 participants were the subject of in depth, extended individual analysis. The other 9 participants received traditional, non-BDM instruction. Interviews which included participants' creation of concept maps and visual field diagrams were conducted after each phase. Various content analyses, including Chi's Verbal Analysis and quantitizing/qualitizing were used for data analysis. The total value added to integrative knowledge during BDM instruction with the three visual fields was an average increase of 56% for cellular respiration

    2008-01-01

    Almost from the moment in June 1977 when the discovery of the Upsilon resonance revealed the existence of what we now call the bottom quark, physicists began searching for its partner. Through the years, as we established the electric charge and weak isospin of the b-quark, and detected the virtual influence of its mate, it became clear that the top quark must exist. Exactly at what mass, we couldn't say, but we knew just how top events would look. We also knew that top events would be rare--if the Tevatron could make them at all--and that picking out the events would pose a real challenge for the experimenters and their detectors.

    Thanks to the unprecedentedly fast accumulation of high-energy data at the LHC during the ongoing Run~2, most of the traditional top-quark analyses are experiencing the luxury of having to worry about how to punch through the ``Systematics Wall'', and think about new ways to maximize the utility of their data. New processes involving top quarks are being studied for the first time, and the good old pair-production processes are being explored in unusual settings, such as collisions involving heavy ions, or ``reference data'' collected by the LHC at relatively low centre-of-mass energy. The TOP2017 conference featured 37 talks delivered by experimental physicists, including seven in the ``Young Scientists Forum'' where young colleagues were given the opportunity to elaborate more deeply than usual on their own work. As it is impossible to do justice to all the experimental resu...

We provide tabulated color transformations for galaxies of different morphologies and luminosities, and analytic expressions for the red sequence shape in different colors. RCSED comprises integrated k-corrected photometry in up to 11 ultraviolet, optical, and near-infrared bands published by the GALEX, SDSS, and UKIDSS wide-field imaging surveys; results of the stellar population fitting of SDSS spectra including best-fitting templates, velocity dispersions, parameterized star formation histories, and stellar metallicities computed for instantaneous starburst and exponentially declining star formation models; parametric and non-parametric emission line fluxes and profiles; and gas phase metallicities. We link RCSED to the Galaxy Zoo morphological classification and galaxy bulge+disk decomposition results of Simard et al. We construct the color-magnitude, Faber-Jackson, and mass-metallicity relations; compare them with the literature; and discuss systematic errors of the galaxy properties presented in our catalog. RCSED is accessible from the project web site and via VO simple spectrum access and table access services using VO-compliant applications. We describe several examples of SQL queries to the database. Finally, we briefly discuss existing and future scientific applications of RCSED and prospective catalog extensions to higher redshifts and different wavelengths. .

    2010-07-01

    3D geological modelling of a tectonic structure called the Monfrague synform has been carried out to obtain a better insight into the geometry of this folding structure. It is a kilometric variscan WNW-ESE trending fold verging towards north and made up by a Palaeozoic sequence (Ordovician-Silurian).This structure with its lithology make up the morphology and the relief of the Park. The Monfrague synform is an asymmetrical folding structure showing southern limb dipping steeply to the south (reverse limb) what is well observed in the Armorican Quartzite at the Salto del Gitano. However, northern limb dips gently (less than 40 degree centigrade) to the south (normal limb). 3D geological modelling has been built on the basis of the geological knowledge and the structural interpretation, using 3D GeoModeller. (www.geomodeller.com). In this software, lithological units are described by a stratigraphic pile. A major original feature of this software is that the 3D description of the geological space is achieved through a potential field formulation in which geological boundaries are isopotential surfaces, and their dips are represented by gradients of the potential. Finally, it is emphasized the idea that a 3D geologic model of these characteristics, with its three-dimensional representation, together with suitable geological sections that clarify the structure in depth, represents a value added to the Geologic Heritage of the National Park and besides it supposes an interesting academic exercise which have a great didactic value.

    The report describes a linear accelerator for protons named TOP LINAC designed for the TOP (Terapia Oncologica con Protoni, Oncological Protontherapy) project launched by the Italian National Institute of Health (Istituto Superiore di Sanita', ISS) to explore in collaboration with the biggest Oncological Hospital in Rome (Istituto Regina Elena, IRE) the potentialities of the therapy with accelerated protons and establish guide lines for the application of this new type of radiotherapy in comparison with the more traditional electron and x-rays radiotherapy. The concept of a compact accelerator for protontherapy applications bore within the Italian Hadrontherapy Collaboration (TERA Collaboration) with the aim to diffuse the protontherapy on the National territory. The ISS program plans to use the TOP linac proton beam also for production of PET (Positron Emission Tomography) radioisotopes and radiobiology studies. Official agreements are in course between ISS and ENEA which provides its experience in the industrial and medical accelerators for the design and the construction of the TOP linac. The accelerator that will be the first 3 GHz proton linac in the world, will be composed of a 428.3 MHz 7 Me V RFQ + DTL injector followed by a 7-65 Me V section of a 3 GHz SCDTL structure and a 65 - 200 Me V variable energy SCL 3 GHz structure. In particular the SCDTL section uses a highly innovative accelerating structure patented by ENEA. In this report the clinical and physical requests are discussed and a preliminary design of the whole machine is given

    The purpose of the final cover of a landfill is to contain the waste and to provide for a physical separation between the waste and the environment for protection of public health. Most landfill covers are designed with the primary goal to reduce or prevent infiltration of precipitation...... into the landfill in order to minimize leachate generation. In addition the cover also has to control the release of gases produced in the landfill so the gas can be ventilated, collected and utilized, or oxidized in situ. The landfill cover should also minimize erosion and support vegetation. Finally the cover...... is landscaped in order to fit into the surrounding area/environment or meet specific plans for the final use of the landfill. To fulfill the above listed requirements landfill covers are often multicomponent systems which are placed directly on top of the waste. The top cover may be placed immediately after...

    In this article the authors look at how the major turbine suppliers fared in the year 2005, and look forward to 2006 which could be the best ever for the wind industry. The world wind turbine market continues to be dominated by ten major companies, who together account for almost 100% of the total global market. Although there are some new companies on the horizon it is the ten major companies that the authors concentrate on, in particular the top three, Vestas, Gamesa and Enercon who between them control 66% of the market. They give their overall report on business in 2005 and give their predictions for 2006. By far the leading wind turbine supplier is the Danish Company Vestas, accounting for over 30% of the global market. However all of the top ten companies report a successful year and all are expecting an even better 2006. This paper also reports on potential newcomers to the industry, one of these is California-based Clipper Windpower which commenced manufacturing the 2.5 MW Liberty turbine in Iowa. Chinese manufacturer Goldwind is also looking to enter the market having acquired a licence to produce the Vensys 1.2 MW turbine. It may well be that changes are on the way, there will be jockeying for position at the top and newcomers will want to make an impression on the market

    We design a search strategy for the Standard Model t t bar t t bar production at the LHC in the same-sign dilepton and trilepton channels. We study different signal features and, given the small expected number of signal events, we scrutinize in detail all reducible and irreducible backgrounds. Our analysis shows that by imposing a basic set of jet and lepton selection criteria, the SM pp → t t bar t t bar process could be evidenced in the near future, within Run-II, when combining both multi-lepton search channels. We argue that this search strategy should also be used as a guideline to test New Physics coupling predominantly to top-quarks. In particular, we show that a non-resonant New Physics enhancement in the four-top final state would be detectable through this search strategy. We study two top-philic simplified models of this kind, a neutral scalar boson and a Z‧, and present current and future exclusion limits on their mass and couplings.

    The ATLAS detector is one of the two multi-purpose experiments located at the Large Hadron Collider (LHC) at CERN and is expected to collect first collision data in summer 2009. Due to the large top-quark production cross-section the LHC will function as a top-quark factory allowing to measure top-quark properties even at initial luminosities. We present some recently-performed studies, focussing on measurements of the top pair and single top production cross-sections with the first fb-1 of data. The potential for the measurement of other top-quark properties like the mass will be also briefly discussed.

    Full Text Available Recent policy interest in tying student learning to teacher evaluation has led to growing use of value-added methods for assessing student learning gains linked to individual teachers. VAM analyses rely on complex assumptions about the roles of schools, multiple teachers, student aptitudes and efforts, homes and families in producing measured student learning gains. This article reports on analyses that examine the stability of high school teacher effectiveness rankings across differing conditions. We find that judgments of teacher effectiveness for a given teacher can vary substantially across statistical models, classes taught, and years. Furthermore, student characteristics can impact teacher rankings, sometimes dramatically, even when such characteristics have been previously controlled statistically in the value-added model. A teacher who teaches less advantaged students in a given course or year typically receives lower effectiveness ratings than the same teacher teaching more advantaged students in a different course or year. Models that fail to take student demographics into account further disadvantage teachers serving large numbers of low-income, limited English proficient, or lower-tracked students. We examine a number of potential reasons for these findings, and we conclude that caution should be exercised in using student achievement gains and value-added methods to assess teachers’ effectiveness, especially when the stakes are high. El reciente interés para relacionar los resultados de los aprendizajes de los estudiantes con las evaluaciones docentes ha provocado un uso creciente de Métodos de Valor Añadido (MVA para evaluar incrementos en los aprendizajes de los alumnos.  Los análisis MVA se basan en hipótesis complejas acerca del papel que desempeñan las escuelas, los profesores

    The invariance of the standard model under CPT transformations leads to the equality of particle and antiparticle masses. The recent measurements performed by the CMS experiment on the top anti-top mass difference are a test of such symmetry. In this work non-perturbative QCD effects, which may eventually lead to an apparent difference in the mass of a top and anti-top quark, are studied.

The proposed model is used in a Digital Archives Project as a means of value adding and knowledge aggregation. We first compared and analyzed multiple wiki engines to select the best system for our research purpose. We chose Taiwanese Baseball News Digital Archive as the base of the research project and the wiki collaboration system as the platform. In order to improve and enhance the quality of digital content, we took the approach of applying techniques of knowledge organization, such as classification, indexing, thesaurus, and controlled vocabularies, so that value and knowledge can be added and aggregated. As the data and community grow, interaction of community members becomes crucial. Therefore, we discussed ways to encourage group interaction and participation from the operational and managerial point of view.

  3. Enhancing the value of commodity polymers: Part 1. Structure-property relationships in composite materials based on maleated polypropylene/inorganic phosphate glasses. Part 2. New value-added applications for polyesters

    Science.gov (United States)

    Gupta, Mohit

    The first part of the thesis (Chapters 2 & 3) describes a new class of organic polymer/inorganic glass composite materials with property improvements that are impossible to achieve with classical polymer blends or composites. These materials exhibit good processability, superior mechanical performance, good thermal stability, and have excellent gas barrier properties. Low glass transition temperature phosphate glasses (Pglass) are used as inorganic fillers and slightly maleated polypropylene is used as the organic polymer matrix. The Pglass, which was dispersed as spherical droplets in the unoriented composites can be elongated into high aspect ratio platelets during the biaxial stretching process. Biaxially oriented films exhibited a brick wall type microstructure with highly aligned inorganic platelets in a ductile organic matrix and the oxygen barrier properties are significantly improved due to presence of Pglass platelets as impermeable inclusions. Mechanical properties of the biaxially oriented films showed significant improvements compared to neat polymer due to uniform dispersion of the Pglass platelets. Properly dispersed and aligned platelets have proven to be very effective for increasing the composite modulus. These developed materials therefore show promise to help fulfill the ever increasing demand for new advanced materials for a wide variety of advanced packaging applications because of their gas barrier properties, flexibility, transparency, mechanical strength and performance under humid conditions. The second part of the thesis (Chapters 4 & 5) describes new value-added applications for polyesters. Chapter 4 reports a novel process for the decolorization of green and blue colored PET bottle flakes using hydrogen peroxide. The decolorized flakes were characterized for color, intrinsic viscosity values. Decolorized flakes exhibited color values similar to those of colorless recycled PET and even though IV values decreased, bleached flakes still

Several signatures of new physics accessible at the LHC either suffer from top-quark production as a significant background or contain top quarks themselves. In this talk, we present results on top quark physics obtained from the first LHC data collected by the CMS experiment.They include measurements of the top pair production cross section in various channels and their combination, measurements of the top quark mass, the single top cross section, a search for new particles decaying into top pairs, and a first look at the charge asymmetry.

    3 lists were compiled to answer the question of what countries have experienced the most population growth from World War II to the present. The 1st list includes the 10 countries which accounted for the largest gain in world population. The 2nd list shows the 10 countries with the highest growth rates of the 150 or so most populous countries in the world. The last list also shows countries ranked by growth rate but is limited to those with a current population of at least 10 million. To deal with the fact that some countries did not exist at 1 of the reference points, a set of estimates for 1940 provided a convenient starting point. China and India headed the list of countries ranked by absolute gains. They contributed half again as much growth as the next 8 nations combined. Altogether Asia, home to almost 60% of the world's population, captured 5 of the top 10 slots. The US and the USSR are the only developed countries on the list. The Soviet Union also presents the 1st case on the list of a country with a lower ranking in population gain (6th) than in absolute size in 1985 (3rd). Many of the population giants of 1940 (Japan, Great Britain, Germany, France, and Italy) are not on the list. Despite large base populations, their growth has been slow in the intervening years. All of the countries with the highest growth rates experienced over 3% annual average growth during the last 45 years: Kuwait, United Arab Emirates, Libya, Venezuela, Costa Rica, Kenya, Ivory Coast, Mexico, Honduras, and Syria. The influence of immigration is much in evidence in this list and explains otherwise unachievable rates of growth. The top 4 countries in annual rates of growth are all oil exporters. The top 3 countries in the 3rd list -- Venezuela, Kenya, and Mexico -- are carried over from the 2nd list, sharing the characteristics of rapid population growth and substantial base populations. The geographic mix of this list is notable. Asia, Africa, and Latin America each have at least

    Full Text Available Purpose of the article: This article presents results of an analysis of sustainable value added created by top 5 European pharmaceutical companies in six different environmental resources. We compare value created in the respective companies to the target EU values. Our results show that in the year 2010 companies’ performance overcame set target. Methodology/methods: Sustainable Value Added is a relatively new method. It was first introduced as a whole concept in 2004 and assesses how companies perform in sustainability. We analyse sustainability performance in six selected environmental areas. As a benchmark we rely on target values for 2010 set by various European institutions. Data for our analysis were retrieved from publicly available resources, e.g. annual, environmental and other reports as well as the companies‘ websites. Scientific aim: Originally, the sustainability concept was initiated in macroeconomics. However, increasing number of companies has incorporated it into their strategies. In this paper we aim to determine whether they succeeded. We present the contribution to sustainability by top five great players on the field of pharmaceutical market in Europe. Findings This paper found several key issues: there is a little research of environmental impact generated by pharmaceutical companies in terms of sustainable value added. Sustainable value added was positive for all analysed companies. It means that successful pharmaceutical companies using six analysed environmental resources create more value than required by the target set. Conclusions: Although sustainable value added determines how well (or bad for that matter a particular company uses its resources compared to a benchmark, it does not judge whether using the total capital in a company can be considered as sustainable or not. Nevertheless, for comparing environmental results of various companies this method is suitable and highly adaptable when using it for analysis

    We present the most recent measurements of top quark pairs production and top quark properties in proton-antiproton collisions with center-of-mass energy of 1.96 TeV using CDF II detector at the Tevatron. The combination of top pair production cross section measurements and the direct measurement of top quark width are reported. The test of Standard Model predictions for top quark decaying into $b$-quarks, performed by measuring the ratio $R$ between the top quark branching fraction to $b$-quark and the branching fraction to any type of down quark is shown. The extraction of the CKM matrix element $|V_{tb}|$ from the ratio $R$ is discussed. We also present the latest measurements on the forward-backward asymmetry ($A_{FB}$) in top anti-top quark production. With the full CDF Run II data set, the measurements are performed in top anti-top decaying to final states that contain one or two charged leptons (electrons or muons). In addition, we combine the results of the leptonic forward-backward asymmetry in $t\\bar t$ system between the two final states. All the results show deviations from the next-to-leading order (NLO) standard model (SM) calculation.

  3. Our top priority

    CERN Multimedia

    2012-01-01

    After three years of LHC running, we are still at the beginning of a long research programme with our flagship facility, and hopefully 4 July 2012 will go down in history as the date of one of many landmark discoveries spanning several years. CERN’s top priority for the next decade and more is the full exploitation of the LHC. With speculation about potential future facilities mounting in the light of the discovery of a new Higgs-like particle, it’s important to state that most clearly. Of course, this will rely on continued global collaboration, and it’s important that CERN engage constructively with other regions.   It is important to plan ahead, particularly since the lead times for new projects in particle physics are long, and our field is increasingly global in nature. That’s why the European particle physics community is currently engaged in updating its long-term strategy. Planning ahead allowed us to be ready technologically to build the LHC whe...

It relies on the reductive cleavage of disulfide bonds within an integrated nanosystem, wherein surface-bound rotaxanes incorporate disulfide bonds in their stalks,-which are encircled by cucurbit[6]uril or α-cyclodextrin rings, until reductive chemistry is performed, resulting in the snapping of the stalks of the rotaxanes, leading to cargo release from the inside of the nanoparticles. © 2010 American Chemical Society.

  8. Pinning down top dipole moments with ultra-boosted tops

    CERN Document Server

    Aguilar-Saavedra, Juan A.; Mangano, Michelangelo L.

    2015-01-01

    We investigate existing and future hadron-collider constraints on the top dipole chromomagnetic and chromoelectric moments, two quantities that are expected to be modified in the presence of new physics. We focus first on recent measurements of the inclusive top pair production cross section at the Tevatron and at the Large Hadron Collider. We then analyse the role of top-antitop events produced at very large invariant masses, in the context of the forthcoming 13-14 TeV runs of the LHC, and at a future 100 TeV proton-proton collider. In this latter case, the selection of semileptonic decays to hard muons allows to tag top quarks boosted to the multi-TeV regime, strongly reducing the QCD backgrounds and leading to a significant improvement in the sensitivity to anomalous top couplings.

  10. Tippe top paradox in relativity

    Science.gov (United States)

    Basu, Aniket; Saraswat, R. S.; Khare, Kedar B.; Sastry, G. P.; Bose, Sougato

    2002-05-01

    If a tippe top is held by its stem and spun fast on a table, it eventually tips over and stands spinning on its stem. For this to happen, the ratios of its principal moments of inertia should fall in a certain regime. Let such a top be observed from a rocket frame in which the top and the table move with a relativistic velocity. The cross-section of the top now appears elliptical due to the length contraction along the line of motion. For a fast enough rocket frame, it is possible that the ratios of the principal moments of inertia go out of the regime required for the top to tip over. However, this is paradoxical. A top that tips over in one frame should tip over in all frames. The paradox is resolved by applying the Lorentz transformation formulae to the equation of motion of the particles of the top, and going over to the spinning coordinates. All the relativistic effects such as the length contraction, time dilation, velocity addition and the lack of synchronization of clocks make their appearance. The orbits of the particles are studied analytically as well as by computer simulation. The movies on the monitor screen reveal the picturesque motion of the particles of the spinning top in the rocket frame, and show in detail how the notion of a rigid body fails in relativistic mechanics. The source code for the computer simulation is included in the appendix.

  11. Top mass from asymptotic safety

    Science.gov (United States)

    Eichhorn, Astrid; Held, Aaron

    2018-02-01

    We discover that asymptotically safe quantum gravity could predict the top-quark mass. For a broad range of microscopic gravitational couplings, quantum gravity could provide an ultraviolet completion for the Standard Model by triggering asymptotic freedom in the gauge couplings and bottom Yukawa and asymptotic safety in the top-Yukawa and Higgs-quartic coupling. We find that in a part of this range, a difference of the top and bottom mass of approximately 170GeV is generated and the Higgs mass is determined in terms of the top mass. Assuming no new physics below the Planck scale, we construct explicit Renormalization Group trajectories for Standard Model and gravitational couplings which link the transplanckian regime to the electroweak scale and yield a top pole mass of Mt,pole ≈ 171GeV.

    This report describes the latest cross section and property measurements associated with the top quark at the Tevatron Run II. The largest data sample used is 760 pb{sup -1} of integrated luminosity. Due to its large mass, the top quark might be involved in the process of electroweak symmetry breaking, making it a useful probe for signs of new physics.

  14. New directions in top physics

    Energy Technology Data Exchange (ETDEWEB)

    Schell, Torben Karl

    2017-02-01

    The top quark plays an important role for many aspects of particle physics. The coupling of the Higgs boson to top quarks is a key parameter to probe electroweak symmetry breaking and is important for the evolution of the Higgs potential to high energies. In addition, many models of physics beyond the Standard Model predict heavy particles that decay to top-quark pairs. Furthermore, the unexplained hierarchy of fermion masses culminates in the large top-quark mass. In this thesis, we consider resonance searches based on top quarks in the fully hadronic final state. We employ multivariate techniques in form of boosted decision trees and add several improvements to the original HEPTopTagger algorithm. These modifications and extensions result in the new HEPTopTagger2. The achieved improvements are used to estimate the precision to which the top Yukawa coupling can be measured at a future 100 TeV proton-proton collider in the fully hadronic final state of t anti tH production. We find that at such a collider a precision measurement of the top Yukawa coupling to 1% should be possible. The statistical precision is backed up by demonstrating that in the ratio σ(t anti tH)/σ(t anti tZ) theoretical uncertainties cancel to below-percent level. Finally, we propose a Froggatt-Nielsen-type model to address the hierarchy of fermion masses in the Standard Model and determine current and projected bounds on the available parameter space.

  19. Uncovering the single top: observation of electroweak top quark production

    Energy Technology Data Exchange (ETDEWEB)

    Benitez, Jorge Armando [Michigan State Univ., East Lansing, MI (United States)

    2009-01-01

    The top quark is generally produced in quark and anti-quark pairs. However, the Standard Model also predicts the production of only one top quark which is mediated by the electroweak interaction, known as 'Single Top'. Single Top quark production is important because it provides a unique and direct way to measure the CKM matrix element Vtb, and can be used to explore physics possibilities beyond the Standard Model predictions. This dissertation presents the results of the observation of Single Top using 2.3 fb-1 of Data collected with the D0 detector at the Fermilab Tevatron collider. The analysis includes the Single Top muon+jets and electron+jets final states and employs Boosted Decision Tress as a method to separate the signal from the background. The resulting Single Top cross section measurement is: (1) σ(p$\\bar{p}$→ tb + X, tqb + X) = 3.74-0.74+0.95 pb, where the errors include both statistical and systematic uncertainties. The probability to measure a cross section at this value or higher in the absence of signal is p = 1.9 x 10-6. This corresponds to a standard deviation Gaussian equivalence of 4.6. When combining this result with two other analysis methods, the resulting cross section measurement is: (2) σ(p$\\bar{p}$ → tb + X, tqb + X) = 3.94 ± 0.88 pb, and the corresponding measurement significance is 5.0 standard deviations.

  20. Search for Top in TOTEM

    CERN Document Server

    Corrales, Alonso

    2017-01-01

    The work assigned to me during this summer (from June 19th to August 11th) was in the "Search for Top in TOTEM" project, a CMG project in collaboration with TOTEM, under the supervision of Martijn Mulders and Laurent Forthomme. The goal is to determine physical properties of the top anti top quark pair (tt) created by central exclusive processes, particularly the invariant mass. For that it is necessary to relate the measurements of the reconstructed top pair kinematics in the central detector of CMS with the detected protons in the Roman Pots of TOTEM just outside the interaction site, about 200 m from it. CMS only considers decay products from the proton collision, it does not regard the forward protons that participated in the collision. On the contrary, TOTEM does consider these protons. In this research measurements of both TOTEM and CMS were combined Figure 1 shows a diagram of the production of the top anti top pair from the interaction of the two protons. A central exclusive process occurs when the pr...

    International Nuclear Information System (INIS)

    Iman, R.L.; Shortencarier, M.J.

    1988-01-01

    1 - Description of program or function: TEMAC is designed to permit the user to easily estimate risk and to perform sensitivity and uncertainty analyses with a Boolean expression such as produced by the SETS computer program. SETS produces a mathematical representation of a fault tree used to model system unavailability. In the terminology of the TEMAC program, such a mathematical representation is referred to as a top event. The analysis of risk involves the estimation of the magnitude of risk, the sensitivity of risk estimates to base event probabilities and initiating event frequencies, and the quantification of the uncertainty in the risk estimates. 2 - Method of solution: Sensitivity and uncertainty analyses associated with top events involve mathematical operations on the corresponding Boolean expression for the top event, as well as repeated evaluations of the top event in a Monte Carlo fashion. TEMAC employs a general matrix approach which provides a convenient general form for Boolean expressions, is computationally efficient, and allows large problems to be analyzed. 3 - Restrictions on the complexity of the problem - Maxima of: 4000 cut sets, 500 events, 500 values in a Monte Carlo sample, 16 characters in an event name. These restrictions are implemented through the FORTRAN 77 PARAMATER statement

  11. Commercial Demonstration of Wood Recovery, Recycling, and Value Adding Technologies

    Energy Technology Data Exchange (ETDEWEB)

    Auburn Machinery, Inc.

    2004-07-15

    This commercial demonstration project demonstrated the technical feasibility of converting low-value, underutilized and waste stream solid wood fiber material into higher valued products. With a growing need to increase product/production yield and reduce waste in most sawmills, few recovery operations and practically no data existed to support the viability of recovery operations. Prior to our efforts, most all in the forest products industry believed that recovery was difficult, extremely labor intensive, not cost effective, and that recovered products had low value and were difficult to sell. This project provided an opportunity for many within the industry to see through demonstration that converting waste stream material into higher valued products does in fact offer a solution. Our work, supported by the U.S. Department of Energy, throughout the project aimed to demonstrate a reasonable approach to reducing the millions of recoverable solid wood fiber tons that are annually treated as and converted into low value chips, mulch and fuel. Consequently sawmills continue to suffer from reduced availability of forest resources, higher raw material costs, growing waste disposal problems, increased global competition, and more pressure to operate in an Environmentally Friendly manner. It is our belief (based upon the experience of this project) that the successful mainstreaming of the recovery concept would assist in alleviating this burden as well as provide for a realistically achievable economic benefit to those who would seriously pursue the concept and tap into the rapidly growing ''GREEN'' building marketplace. Ultimately, with participation and aggressive pursuit of the recovery concept, the public would benefit in that: (1) Landfill/disposal waste volume could be reduced adding greater life to existing municipal landfill sites thereby minimizing the need to prematurely license and open added facilities. Also, there would be a cost avoidance benefit associated to what would have been the added municipal (community) management costs involved with maintaining closed landfills. (2) With greater quantities of recovered material being returned to and integrated into manufacturing and the marketplace, reduced demand upon virgin wood sources could help lead the way to promoting improved relations and environmental balance between producers and consumers further expanding the value of our natural resource without adding environmental burden.

    It is difficult for large research facilities to quantify a return on the investments that fund their operations. This is because there can be a time lag of years or decades between an innovation or discovery and the realization of its value through practical application. This report presents a three-part methodology that attempts to assess the value of federal investment in XSEDE: 1) a qualitative examination of the areas where XSEDE adds value to the activities of the open research community, 2) a thought model examining the cost avoidance realized by the National Science Foundation (NSF) through the centralization and coordination XSEDE provides, and 3) an assessment of the value XSEDE provides to Service Providers in the XD ecosystem. XSEDE adds significantly to the US research community because it functions as a unified interface to the XD ecosystem and because of its scale. A partly quantitative, partly qualitative analysis suggests the Return on Investment of NSF spending on XSEDE is greater than 1.0. indicating that the aggregate value received by the nation from XSEDE is greater than the cost of direct federal investment in XSEDE.

  16. Australian Nurse Practitioner Practice: Value Adding through Clinical Reflexivity

    Full Text Available The role of the Australian Nurse Practitioner (NP is in its infancy and at a crossroads where extensive research demonstrates effective quality care and yet the role remains underrecognised and underutilised. The translation of practice into “value” is critical for the sustainability of NP roles and requires the practitioner to adopt a systematic method of inquiry. Kim’s (1999 “Critical Reflective Inquiry” (CRI method was adapted by two Australian NPs who specialise in diabetes and chronic disease management. Kim highlights the intent of CRI as understanding the meaning of practice, delivering improvements to practice through self-reflection, and the critique of practice that can lead to practice changes and development of new models of care translated to “products” of value. Based on the thematically analysis of 3 years of CRI application, the authors formed 5 headings that represented the NP’s practice as Specialised Care Access, Complications and Diagnostics Interventions, Pharmaceutical Treatment, Vulnerable Populations, and Leadership. The utility of CRI demonstrates how NP practice is integral to a continuous cycle of addressing health care services gaps, and the conversion of “products” into “value” and positions the NP to assimilate the role of the practitioner-researcher.

    Full text: Bleaching earth is used in the bleaching process of physical refining of palm oil to remove color, phospholipids, residue gums, oxidized products and any trace metals from the oil. These colored pigments are trapped and absorbed in the bleaching earth, thus transforming the originally whitish earth to dark grey and is, from then, named spent bleaching earth (SBE). SBE is considered as an industrial by-product as there is hardly any practical application for it. Large quantity of SBE is commonly disposed of in landfills, which poses potential hazards to environment. New economical ways in utilizing it is sought to eliminate the problem arises from its disposal. This paper presents a study on the possibility of developing a soil conditioner using enhanced SBE as the base material. The study found that there are certain attributes observed in the enhanced SBE that could be of advantages for SBE to become a good soil conditioner. The enhanced SBE contains organic matters and about 18-20 % of residue oil which exhibits good water holding capacity in slow release of water, and enriched nutrient content for plant nutrient uptake.

  18. Organic Aerosol Component (OACOMP) Value-Added Product

    Organic aerosol (OA, i.e., the organic fraction of particles) accounts for 10–90% of the fine aerosol mass globally and is a key determinant of aerosol radiative forcing. But atmospheric OA is poorly characterized and its life cycle insufficiently represented in models. As a result, current models are unable to simulate OA concentrations and properties accurately. This deficiency represents a large source of uncertainty in quantification of aerosol effects and prediction of future climate change. Evaluation and development of aerosol models require data products generated from field observations. Real-time, quantitative data acquired with aerosol mass spectrometers (AMS) (Canagaratna et al. 2007) are critical to this need. The AMS determines size-resolved concentrations of non-refractory (NR) species in submicrometer particles (PM1) with fast time resolution suitable for both ground-based and aircraft deployments. The high-resolution AMS (HR-AMS), which is equipped with a high mass resolution time-of-flight mass spectrometer, can be used to determine the elemental composition and oxidation degrees of OA (DeCarlo et al. 2006).
