Financing alternatives and incentives for solar-thermal central-receiver systems

Energy Technology Data Exchange (ETDEWEB)

Bos, P.B.

1982-07-01

As a result of various recently enacted incentive and regulatory legislation combined with the new administration policy and budgetary guidelines, the commercialization of solar thermal central receiver systems will involve financing alternatives other than conventional utility financing. This study was conducted to identify these potential financing alternatives and the associated requirements and impacts on the Department of Energy program. Based upon this analysis, it is concluded that the current alternative financing window is extremely short (through 1985), and that an extension or at the least a gradual phasing out, of the solar tax credits is necessary for the successful transfer of the central receiver technology to the private sector. Furthermore, throughout this time period, continued government support of the R and D activities is necessary to provide the necessary confidence in this technology for the private (financial) sector to underwrite this technology transfer. Consequently, even though the central receiver technology shows high promise for replacing a significant fraction of the oil/gas-fired utility industry peaking and intermediate generation, the current readiness status of this technology still requires further direct and indirect government support for a successful technology transfer. The direct government research and development support will provide the basis for a technological readiness and confidence, whereas the indirect tax incentive support serves to underwrite the extraordinary risks associated with the technology transfer. These support requirements need only be limited to and decreasing during this technology transfer phase, since as the systems approach successful full-scale commercialization, the extraordinary risks will be gradually eliminated. At the time of commercialization the system's value should be on a par with the installed system's cost.

In this experimental work, tall oil methyl ester-diesel fuel blends as alternative fuels for diesel engines were studied. Tall oil methyl ester was produced by reacting tall oil fatty acids with methyl alcohol under optimum conditions. The blends of tall oil methyl ester-diesel fuel were tested in a direct injection diesel engine at full load conditions. The effects of the new fuel blends on the engine performance and exhaust emission were tested. It was observed that the engine torque and power output with tall oil methyl ester-diesel fuel blends increased up to 6.1% and 5.9%, respectively. It was also seen that CO emissions decreased to 38.9% and NO{sub x} emissions increased up to 30% with the new fuel blends. The smoke capacity did not vary significantly. (author)

Mumford, E.B. Jr.

1993-01-01

Biomass-energy and alternative-fuels projects make environmental sense, but do they make economic sense? In the current project-finance environment, moving ideas off the drawing board and transforming them into reality takes more than vision and commitment; it takes the ability to understand and address the financial markets' perception of risk. This paper examines the state of the project-finance market, both as it pertains to biomass and alternative-fuels projects and in more general terms, focusing on what project sponsors and developers need to dot to obtain both early-state and construction/term financing, and the role a financial adviser can play in helping ensure access to funds at all stages

Full Text Available BACKGROUND. The main source of state public health institutions financing in Ukraine is budgetary funding. In order to overcome the underfunding, the idea of multichannel health financing was proposed in the late 1990s. The main forms of extrabudgetary financial support of public health institutions in Ukraine are voluntary health insurance, non-profit self-financing, charity and sponsorship. The study aims to deeper understand the nature of alternative financing mechanisms of state public health institutions in Ukraine and peculiarities of their use in practice.METHODS. The proposed study is exploratory. Case-study was selected as research method. Nine unstructured interviews were conducted in six health care facilities that have agreed to participate in the study. All studied facilities were in-patient.RESULTS. The sources of financial revenues of the studied institutions were as follows: reimbursement for treatment of insured patients, reimbursement for treatment of sickness funds members, payments for services (medical examinations, counseling, transportation to the hospital, rental of premises, payment for internship from the students of paid forms of medical education, charitable contributions, contracts with companies, contracts with private clinics based in public institutions’ premises (limited liability companies, private entrepreneurs, sponsorship, grants, gifts, payments for services for foreigners, and in-kind revenues. Major health facilities expenditures were the following: salaries (not covered from extrabudgetary revenues; ranged from 70% to 92% of the funds provided to the institutions from state (municipal, regional budget, energy carriers (partially covered from extrabudgetary funds, patients nutrition, medicines, materials, household expenditures, reparation of premises, and purchase of equipment (mostly covered from extrabudgetary revenues.

2017-01-01

Full Text Available The world faces the crises of energy demand, rising petroleum prices and depletion of fossil fuel resources. Biodiesel has obtained from vegetable oils that have been considered as a promising alternate fuel. The researches regarding blend of diesel and single biodiesel have been done already. Very few works have been done with the combination of two different biodiesel blends with diesel and left a lot of scope in this area. The present study brings out an experiment of two biodiesels from pongamia pinnata oil and mustard oil and they are blended with diesel at various mixing ratios. The effects of dual biodiesel works in engine and exhaust emissions were examined in a single cylinder, direct injection, air cooled and high speed diesel engine at various engine loads with constant engine speed of 3000 rpm. The influences of blends on CO, CO2, HC, NOx and smoke opacity were investigated by emission tests. The brake thermal efficiency of blend A was found higher than diesel. The emissions of smoke, hydro carbon and nitrogen oxides of dual biodiesel blends were higher than that of diesel. But the exhaust gas temperature for dual biodiesel blends was lower than diesel.

Jatropha oil methyl ester and its blends used as an alternative fuel in diesel engine

Directory of Open Access Journals (Sweden)

Yarrapathruni Rao Hanumantha Venkata

2009-01-01

Full Text Available Biomass derived vegetable oils are quite promising alternative fuels for agricultural diesel engines. Use of vegetable oils in diesel engines leads to slightly inferior performance and higher smoke emissions due to their high viscosity. The performance of vegetable oils can be improved by modifying them through the transesterification process. In this present work, the performance of single cylinder water-cooled diesel engine using methyl ester of jatropha oil as the fuel was evaluated for its performance and exhaust emissions. The fuel properties of biodiesel such as kinematic viscosity, calorific value, flash point, carbon residue, and specific gravity were found. Results indicate that B25 has closer performance to diesel and B100 has lower brake thermal efficiency mainly due to its high viscosity compared to diesel. The brake thermal efficiency for biodiesel and its blends was found to be slightly higher than that of diesel fuel at tested load conditions and there was no difference of efficiency between the biodiesel and its blended fuels. For jatropha biodiesel and its blended fuels, the exhaust gas temperature increased with the increase of power and amount of biodiesel. However, its diesel blends showed reasonable efficiency, lower smoke, and CO2 and CO emissions.

Full Text Available Financial crises have become a recurring problem for modern economies with increasingly detrimental fallouts. Risk-sharing finance (RSF contracts may be the best instrument for addressing the problem and its fallout, and in particular the risk-sharing principles of Islamic finance offer a potential alternative. This paper offers some preliminary thoughts on the design and implementation of RSF for both private and public sector funding, for revenue and non-revenue generating projects. It is argued that such form of financing avoids the leverage of conventional debt, minimizes the costs of dilution, reduces macroeconomic vulnerability, and enhances financial inclusion. It also has the potential to be a less risky alternative for developing countries to finance public spending and economic growth. JEL Classifications: G32, P43, O16

The primary data is collected from the administered survey questions in Klang Valley (Selangor and Kuala Lumpur and the analysis is conducted using statistical analysis and Structural Equation Modeling (SEM. The model is validated its acceptance in the field by adopting the Theory of Reasoned Action (TRA. From the findings, among the factors that lead micro enterprises to use internal funding are strict collateral requirement by commercial financial institutions, high cost of financing, strict documentation requirement and good financial and business track record. Unfortunately, most of them cannot fulfill these conditions and continue to face the problem of accessing finance. The present study has developed the Cash Waqf Investment model to support micro enterprises to improve their access to finance and enhance the skills. Based on the responses received from the field, it has been shown that the intention and readiness of micro enterprises in accepting the model as a source of financial and human capital development services is impressive.

The United States Department of Energy (DOE) is examining options for the disposition of surplus weapons-usable fissile materials and storage of all weapons-usable fissile materials. Disposition is a process of use or disposal of material that results in the material being converted to a form that is substantially and inherently more proliferation-resistant than the original form. Examining options for increasing the proliferation resistance of highly enriched uranium (HEU) is part of this effort. This document provides data to be used in the environmental impact analysis for the oxide blending HEU disposition option. This option provides for a yearly HEU throughput of 1 0 metric tons (MT) of uranium metal with an average U235 assay of 50% blended with 165 MT of natural assay triuranium octoxide (U 3 O 8 ) per year to produce 177 MT of 4% U235 assay U 3 O 8 , for LWR fuel.

Royalty financing for the oil and gas industry

International Nuclear Information System (INIS)

Read, F. M. D.

1998-01-01

Key concepts in royalty financing for the oil and gas industry are described. The basic significance of royalty financing for a public company is that financing is 'off balance sheet', and can be used to achieve objectives that neither debt, equity, nor outright sale of assets or farm-outs can accomplish. Royalty financing can provide increased available capital or debt reduction while maintaining the full gross share of reserve and production volumes on the books. This paper provides an overview of the field of royalty financing, with an appreciation of the benefits, reviews each of the financial alternatives (debt, equity, farmout and or sale of assets to reduce capital requirements), and provides examples of specific application of royalty financing. It is claimed that this type of financing, which has been available to the mining sector for some time, is a useful alternative to other financing instruments to acquire new oil and gas assets, to develop new areas, to implement enhanced recovery projects or to carry out mergers and acquisitions. Used judiciously, royalty financing can provide significant benefits to both the working interest owner and his shareholders, as well as the royalty company

Windpower project ownership and financing: The cost impacts of alternative development structures

Energy Technology Data Exchange (ETDEWEB)

Wiser, R.H. [Lawrence Berkeley National Lab., CA (United States)

1997-12-31

This paper uses traditional financial cash-flow techniques to examine the impact of different ownership and financing structures on the cost of wind energy. While most large-scale wind projects are constructed, operated, and financed by non-utility generators (NUGs) via project financing, investor- and publicly-owned utilities have expressed interest in owning and financing their own facilities rather than purchasing wind energy from independent generators. A primary justification for utility ownership is that, because of financing and tax benefits, windpower may be cheaper when developed in this fashion. The results presented in this paper support that justification, though some of the estimated cost savings associated with utility ownership are found to be a result of shortcomings in utility analysis procedures and implicit risk shifting. This paper also discusses the comparative value of the federal production tax credit and renewable energy production incentive; estimates the financing premium paid by NUG wind owners compared to traditional gas-fired generation facilities; and explores the impact of electricity restructuring on financing.

Public and private health-care financing with alternate public rationing rules.

Cuff, Katherine; Hurley, Jeremiah; Mestelman, Stuart; Muller, Andrew; Nuscheler, Robert

2012-02-01

We develop a model to analyze parallel public and private health-care financing under two alternative public sector rationing rules: needs-based rationing and random rationing. Individuals vary in income and severity of illness. There is a limited supply of health-care resources used to treat individuals, causing some individuals to go untreated. Insurers (both public and private) must bid to obtain the necessary health-care resources to treat their beneficiaries. Given individuals' willingnesses-to-pay for private insurance are increasing in income, the introduction of private insurance diverts treatment from relatively poor to relatively rich individuals. Further, the impact of introducing parallel private insurance depends on the rationing mechanism in the public sector. We show that the private health insurance market is smaller when the public sector rations according to need than when allocation is random. Copyright © 2010 John Wiley & Sons, Ltd.

In the paper I presented several defining elements of this financing practice of social projects or companies, ranging from a quick evolution over time and a presentation of the theoretical concept to a statistical presentation of the number of crowdfunding platforms and also of the amounts collected worldwide, thanks to them. In the second part of the paper we presented the three major platforms in Romania and some of the projects financed entirely due to their help. At the end of the paper one may find legislative guidance regarding crowdfunding in the USA, Europe and Romania.

Financing nuclear power

Global energy security and climate change concerns sparked by escalating oil prices, high population growth and the rapid pace of industrialization are fueling the current interest and investments in nuclear power. Globally, a significant number policy makers and energy industry leaders have identified nuclear power as a favorable alternative energy option, and are presently evaluating either a new or an expanded role for nuclear power. The International Atomic Energy Agency (IAEA) has reported that as of October 2008, 14 countries have plans to construct 38 new nuclear reactors and about 100 more nuclear power plants have been written into the development plans of governments for the next three decades. Hence as new build is expected to escalate, issues of financing will become increasingly significant. Energy supply, including nuclear power, considered as a premium by government from the socio-economic and strategic perspective has traditionally been a sector financed and owned by the government. In the case for nuclear power, the conventional methods of financing include financing by the government or energy entity (utility or oil company) providing part of the funds from its own resources with support from the government. As national financing is, as in many cases, insufficient to fully finance the nuclear power plants, additional financing is sourced from international sources of financing including, amongst others, Export Credit Agencies (ECAs) and Multilateral Development Institutions. However, arising from the changing dynamics of economics, financing and business model as well as increasing concerns regarding environmental degradation , transformations in methods of financing this energy sector has been observed. This paper aims to briefly present on financing aspects of nuclear power as well as offer some examples of the changing dynamics of financing nuclear power which is reflected by the evolution of ownership and management of nuclear power plants

Development of Briquette from Coir Dust and Rice Husk Blend: An Alternative Energy Source

Md. Hamidul Islam

2014-05-01

Full Text Available Biomass is one of the predominant renewable energy sources and the use of biomass for the energy generation has got much attention due to its environmental friendliness. Densification of coir dust into fuel briquette can solve waste disposal problem as well as can serve as an alternative energy source. The objective of this study was to investigate the possibility of producing briquette from coir dust and rice husk blend without binder. During this study, a briquetting experiment was conducted with different coir dust and rice husk blends (i.e. coir dust and rice husk ratio of 80:20, 60:40, 50:50, 40:60, 20:80 and 0:100. Briquetting operation was performed using a die-screw press type briquetting machine. The briquettes were tested to evaluate their density, compressive strength, calorific value, burning rate and water vaporizing capacity and it was found that mixing ratio had a significant effect on the physical, mechanical and combustion properties of the coir dust-rice husk briquettes. Density, compressive strength and calorific value and water vaporizing capacity were increased with increasing mixing ratio while burning rate was decreased. Coir dust-rice husk briquettes with mixing ratio of 20:80 had higher density (1.413 g/cm3, compressive strength (218.4 N/cm2, calorific value (4879 kcal/kg, water vaporizing capacity (0.853 l/kg and low burning rate (0.783 kg/hour followed by the mixing ratio 40:60, 50:50, 60:40 and 0:100. The results indicate that coir dust and rice husk blend briquettes were found to have better overall handling characteristics over rice husk briquette. However, production of briquettes from coir dust and rice husk at mixing ratio of 50:50 was found to be more suitable for commercial application in terms of cost effectiveness.

Alternatives to the EEG levy. Possible effects of a reform of the energy transition financing on the industry

Although it has been adjusted six times since the year 2000, it has not yet been possible to manage the unrestricted growth of the EEG levy. In the 2017 election year, it becomes therefore ever more obvious that an alternative way to finance the energy transition is high on the political agenda. This would lead to significant changes for energy-intensive companies, regardless of whether they have benefited from a release from the levy or not. At the same time, the alternatives currently discussed have quite different effects on the industrial companies concerned and thereby the industry location Germany. [de

Financing investment in environmentally sound technologies: Foreign direct investment versus foreign debt finance

International Nuclear Information System (INIS)

Anyangah, Joshua Okeyo

2010-01-01

This paper develops a screening model to examine the relationship between alternative sources of private capital and investment in environmentally sound technologies (ESTs). In the model, a polluter (agent) must secure investment funds from the international financial markets in order to upgrade its production and abatement technology. The requisite capital can be obtained via either market loans (debt finance) or foreign direct investment (FDI). Under debt finance, the foreign financier supplies only capital and the relationship between the two parties is more 'arms-length'. By contrast, under FDI, the investor delivers both capital and managerial skills. We use the model to derive the implications of debt finance for optimal investment decisions and compare them to those obtained under FDI. Investment incentives are more pronounced under debt finance. (author)

Internet finance: Digital currencies and alternative finance liberating the capital markets

Directory of Open Access Journals (Sweden)

Kim Wales

2015-09-01

Full Text Available This article discusses how the sudden shift in policy reform and innovation has the potential to liberate the financial markets. The economic potential of internet finance is beginning to take hold across the capital markets as industries like Peer – to – Peer Lending, Equity and Debt based Crowdfunding and virtual currencies and cryptocurrencies which are types of digital currency are quickly transforming the way businesses are being financed. From borrowing and lending, buying and selling securities, to conducting wire transfers internationally, these innovations are creating a new class and generation of investors will source investments opportunities. Helping institutions and governments assess risks and manage performance in order to determine where to deploy capital; and showing signs of lessening the inequality gap. Following the neolithic agricultural revolution and the industrial revolution, this new revolution will enable more people to access financial services in less traditional ways, especially the unbanked world with its huge potential. These new financial opportunities, such as peer – to - peer (P2P lending, will be discussed and examined, and we will stress how they can allow people to bypass current barriers in the global economy. We conclude by arguing that all these developments, energized by the efforts of innovators and entrepreneurs, have the potential to radically transform the world in which we live, while promoting the core values of industrialized societies including democracy, capital formation, sustainability, and equality without solely relying on tax increases

The logic of tax-based financing for health care.

Science.gov (United States)

Bodenheimer, T; Sullivan, K

1997-01-01

Employment-based health insurance faces serious problems. For the first time, the number of Americans covered by such health insurance is falling. Employers strongly oppose the employer mandate approach to extending health insurance. Employment-based financing is regressive and complex. Serious debate is needed on an alternative solution to financing health care for all Americans. Taxation represents a clear alternative to employment-based health care financing. The major criterion for choosing a tax is equity, with simplicity a second criterion. An earmarked, progressive individual income tax is a fair and potentially simple tax with which to finance health care. The political feasibility of such a tax is greater than that of employer mandate legislation.

Hydrogen-ethanol blending as an alternative fuel of spark ignition engines

Energy Technology Data Exchange (ETDEWEB)

Al-Baghdadi, M.A.S. [University of Babylon (Iraq). Dept. of Mechanical Engineering

2003-07-01

The performance and pollutant emission of a four-stroke spark ignition engine using hydrogen-ethanol blends as fuel have been studied. The tests were performed using 2, 4, 6, 8, 1 0 and 12 mass% hydrogen-ethanol blends. Gasoline fuel was used as a basis for comparison. The effect of using different blends of hydrogen-ethanol on engine power, specific fuel consumption, CO and NO{sub x} emission was studied. Operating test results for a range of compression ratio (CR) and equivalent ratio are presented. The results show that the supplemental hydrogen in the ethanol-air mixture improves the combustion process and hence improves the combustion efficiency, expands the range of combustibility of the ethanol fuel, increases the power, reduces the s.f.c. and reduces toxic emissions. The important improvement of hydrogen addition is to reduce the s.f.c. of ethanol engines. Results were compared to those with gasoline fuel at 7 CR and stoichiometric equivalence ratio. (author)

Clausen, C C; Bauer, M; Saleh, A; Picker, O

2008-07-01

In part 1 of this series about problems of financing capital goods the multiple and partly diametric economic effects of financing instruments were presented using the leasing procedure as an example. The result indicated that due to the complexity of these effects the choice of a specific financing instrument requires an individual consideration. Therefore, part 2 of the series introduces the method of dynamic capital budgeting which allows the instruments discussed in part 1 to be compared with each other and helps to evaluate their economic benefits. More precisely this paper focuses on a comparative analysis of the most common alternatives, leasing, credit financing and investment financing by the state. In this context, after having identified the total costs of ownership of anesthesia devices, the final asset values of the three financing instruments can be compared with each other using the method of dynamic capital budgeting. In contrast to the prevailing opinion, the results show that from a purely fiscal perspective leasing anesthesia devices is the most expensive alternative. Given the fact that no financial support is available from the state, the option of credit financing turns out to be the most preferable alternative from a relatively limited pool of possibilities. However, it still remains to be answered whether credit financing can defend this position against further, innovative forms of debt financing (e.g., factoring, asset-backed securities, hedge funds, mezzanine capital, etc.).

In order to meet rapidly growing demand for fuel, as well as address environmental concerns, the aviation industry has been testing alternate fuels for performance and technical usability in commercial and military aircraft. Currently, alternate aviation fuels must satisfy MIL-DTL- 83133F(2008) (military) or ASTM D 7566- Annex(2011) (commercial) standards and are termed drop-in fuel replacements. Fuel blends of up to 50% alternative fuel blended with petroleum (JP-8), which have become a practical alternative, are individually certified on the market. In order to make alternate fuels (and blends) a viable option for aviation, the fuel must be able to perform at a similar or higher level than traditional petroleum fuel. They also attempt to curb harmful emissions, and therefore a truly effective alternate fuel would emit at or under the level of currently used fuel. This paper analyzes data from gaseous and particulate emissions of an aircraft combustor sector. The data were evaluated at various inlet conditions, including variation in pressure and temperature, fuel-to-air ratios, and percent composition of alternate fuel. Traditional JP-8+100 data were taken as a baseline, and blends of JP- 8+100 with synthetic-paraffinic-kerosene (SPK) fuel (Fischer-Tropsch (FT)) were used for comparison. Gaseous and particulate emissions, as well as flame luminosity, were assessed for differences between FT composition of 0%, 50%, and 100%. The data showed that SPK fuel (a FT-derived fuel) had slightly lower harmful gaseous emissions, and smoke number information corroborated the hypothesis that SPK-FT fuels are cleaner burning fuels.

FACTORING – ALTERNATIVE OF SHORT-TERM FINANCING FOR COMPANIES

Full Text Available In developed countries, had been created formidable conditions for encouraging the factoring business, because using this instrument of investment and financing have grown the economic and financial stability of the company and generated a more efficient management of accounts receivable by the policy of claims recovering. Also, the factoring may be considered both a commercial and financial activity. The essential role of the factoring companies is given by taking the place of company in activities that are not referring exclusively to the commercial field. Given the importance of this financing operation, in this paper are presented different ways of defining, their importance, advantages and disadvantages for the company, the return for the factoring of accounts receivables and the real cost of factoring.

Perspectives applicable to financing midstreamers: legal considerations

International Nuclear Information System (INIS)

Park, J. J.

2000-01-01

Systemic changes that have affected the sale, distribution and transportation of gas near the burner tip (collectively called 'midstream' activities) are reviewed, examining the causes of change, and the types of midstream asset transactions that are occurring, whether they involve structured financing arrangements or midstream companies. Also addressed are issues involved in transactions of this type, especially as they relate to gathering and processing agreements and construction, ownership and operation (CO and O) agreements. The two principal alternative structures (1) the financing party who does not assume operational control of the facility, and the (2) midstream company who build or acquire assets and operate them, the different implications for financing of each of the structural alternatives and the changing attitudes of producers towards midstream entities are explained. Closer examination of these new business structures reveals that they conflict with the terms and conditions of midstream agreements commonly used throughout the industry. It is recommended that these standard agreements be amended to permit midstream transactions to occur without undue restrictions. The kind of amendments suggested include automatic consent to a transfer of a facility to a Financing Party that meets certain reasonable financial tests; allowing the reconveyance from the Financing Party to the producer under a repurchase option; allowing the producer to act as Operator in place of its Financing Party

Radiation crosslinking of polymer blends

International Nuclear Information System (INIS)

Spenadel, L.

1979-01-01

Rocked by the one-two punch of rising energy costs and tougher pollution controls, a growing number of companies are looking to radiation crosslinking as a cheaper, cleaner alternative to heat and costly chemical crosslinking agents such as peroxides. With the development of larger, more powerful electron beam machines it is now possible to irradiate parts as thick as 400 mils in a single pass. Two application areas which have been investigated at our laboratory are the electron beam processing of thermoplastic elastomeric automotive parts and EPDM electrical insulation. This paper covers work carried out to develop the necessary technology base for the radiation crosslinking of ethylene propylene/polyolefin blends. Initial results indicate that EP/PE blends of electrical insulation quality cross-link quite readily when irradiated. On the other hand, EP/PP blends developed for automotive fascia require the addition of crosslinking monomers such as trimethylol propane trimethacrylate in order for crosslinking to predominate over chain scission. Crosslinking EP/PP blends improve mar resistance, flexural set and deformation at elevated temperatures. These are all key properties for automotive fascia. (author)

The way a country finances its health care system is a critical determinant for reaching universal health coverage (UHC). This is so because it determines whether the health services that are available are affordable to those that need them. In Nigeria, the health sector is financed through different sources and mechanisms. The difference in the proportionate contribution from these stated sources determine the extent to which such health sector will go in achieving successful health care financing system. Unfortunately, in Nigeria, achieving the correct blend of these sources remains a challenge. This review draws on relevant literature to provide an overview and the state of health care financing in Nigeria, including policies in place to enhance healthcare financing. We searched PubMed, Medline, The Cochrane Library, Popline, Science Direct and WHO Library Database with search terms that included, but were not restricted to health care financing Nigeria, public health financing, financing health and financing policies. Further publications were identified from references cited in relevant articles and reports. We reviewed only papers published in English. No date restrictions were placed on searches. It notes that health care in Nigeria is financed through different sources including but not limited to tax revenue, out-of-pocket payments (OOPs), donor funding, and health insurance (social and community). In the face of achieving UHC, achieving successful health care financing system continues to be a challenge in Nigeria and concludes that to achieve universal coverage using health financing as the strategy, there is a dire need to review the system of financing health and ensure that resources are used more efficiently while at the same time removing financial barriers to access by shifting focus from OOPs to other hidden resources. There is also need to give presidential assent to the national health bill and its prompt implementation when signed into law.

Smith, Samantha

2010-04-01

This paper employs widely used analytic techniques for measuring equity in health care financing to update Irish results from previous analysis based on data from the late 1980s. Kakwani indices are calculated using household survey data from 1987/88 to 2004/05. Results indicate a marginally progressive financing system overall. However, interpretation of the results for the private sources of health financing is complicated. This problem is not unique to Ireland but it is argued that it may be relatively more important in the context of a complex health financing system, illustrated in this paper by the Irish system. Alternative options for improving the analysis of equity in health care financing are discussed.

Biodiesel is a promising alternative fuel to run the automotive engine. However, its blends have not been properly investigated during idling as it is the main problem to run the vehicles in a big city. The purpose of this study is to evaluate the impact of alcohol additives such as butanol and ethanol on combustion parameters under idling conditions when a single cylinder diesel engine operates with diesel, diesel-biodiesel blends, and diesel biodiesel-alcohol blends. The engine combustion parameters such as peak pressure, heat release rate and ignition delay were computed. This investigation has revealed that alcohol blends with diesel and biodiesel, BU20 blend yield higher maximum peak cylinder pressure than diesel. B5 blend was found with the lowest energy release among all. B20 was slightly lower than diesel. BU20 blend was seen with the highest peak energy release where E20 blend was found advance than diesel. Among all, the blends alcohol component revealed shorter ignition delay. B5 and B20 blends were influenced by biodiesel interference and the burning fraction were found slightly slower than conventional diesel where BU20 and E20 blends was found slightly faster than diesel So, based on the result, it can be said that among the alcohol blends butanol and ethanol can be promising alternative at idling conditions and can be used without any engine modifications.

Full Text Available Recent research on biodiesel focused on performance of single biodiesel and its blends with diesel. The present work aims to investigate the possibilities of the application of mixtures of two biodiesel and its blends with diesel as a fuel for diesel engines. The combinations of Pongamia pinnata biodiesel, Mustard oil biodiesel along with diesel (PMD and combinations of Cotton seed biodiesel, Pongamia pinnata biodiesel along with diesel (CPD are taken for the experimental analysis. Experiments are conducted using a single cylinder direct-injection diesel engine with different loads at rated 3000 rpm. The engine characteristics of the two sets of double biodiesel blends are compared. For the maximum load, the value of Specific Fuel consumption and thermal efficiency of CPD-1 blend (10:10:80 is close to the diesel values. CPD blends give better engine characteristics than PMD blends. The blends of CPD are suitable alternative fuel for diesel in stationary/agricultural diesel engines.

Vegetable oil presents a very promising alternative to diesel oil since it is renewable and has similar properties to the diesel. In view of this, crude jatropha oil is selected and its viscosity is reduced by blending it with diesel. Since jatropha oil has properties which are similar to mineral diesel, it can be used in compression ignition engines without any engine modification. This paper presents the results of investigation carried out on a four-cylinder, four strokes and indirect-injection diesel engine. The engine, operated using composition blends of crude jatropha oil and diesel, were compared with mineral diesel. An experimental investigation has been carried out to analyze the performance characteristics of a compression ignition engine from the blended fuel (5%, 10%, 20% and 30%). A naturally aspirated four-stroke indirect injection diesel engine was tested at full load conditions, speeds between 1000 and 3500 rpm with intervals of 500 rpm. Results obtained from the measures of torque, power, specific fuel consumptions, thermal efficiency and brake mean effective pressure are nearly the same between blended and diesel fuel. An overall graph shows that the performance of relevant parameters from blended fuel is most likely similar to the performance produced from diesel. The experimental results proved that the use of crude jatropha oil in compression ignition engines is a viable alternative to diesel.

Mitigation incentives with climate finance and treaty options

International Nuclear Information System (INIS)

Strand, Jon

2016-01-01

Future greenhouse gas (GHG) mitigation action of current non-climate-policy (NP) countries is considered to take two alternative forms: 1) “climate finance” payments received in return for future reductions in its GHG emissions below a defined “baseline”; and 2) join a “climate treaty” whereby the required emissions reductions are formally binding. It is assumed that baselines defining climate finance payments, and required emissions reductions under a treaty, depend positively on current emissions. It is then shown that making such future options available reduces current GHG mitigation in NP countries, leading to higher emissions in the short run. This effect is stronger when future climate finance payments are higher; the required relative emissions reductions under a treaty are greater; when commitments under a treaty are longer-lasting; and mitigation targets depend more on current emissions. Such short-run increases in emissions can (sometimes, more than) fully eliminate the effect of the subsequent policy. When climate finance and treaties are both future alternatives, more generous climate finance can make it harder and more expensive to induce the country to join a climate treaty. - Highlights: • A good future climate finance arrangement can increase GHG emissions today. • The same can be the case with a future and restrictive climate treaty. • These can be problems when costs under such solutions are reduced by higher emissions today. • Better climate finance also tends to make joining a climate treaty less attractive.

In physiological education, blended course formats (integration of face-to-face and online instruction) can facilitate increased student learning, performance, and satisfaction in classroom settings. There is limited evidence on the effectiveness of using blending course formats in laboratory settings. We evaluated the impact of blended learning on student performance and perceptions in an undergraduate exercise physiology laboratory. Using a randomized, crossover design, four laboratory topics were delivered in either a blended or traditional format. For blended laboratories, content was offloaded to self-paced video demonstrations (∼15 min). Laboratory section 1 (n = 16) completed blended laboratories for 1) neuromuscular power and 2) blood lactate, whereas section 2 (n = 17) completed blended laboratories for 1) maximal O2 consumption and 2) muscle electromyography. Both sections completed the same assignments (scored in a blinded manner using a standardized rubric) and practicum exams (evaluated by two independent investigators). Pre- and postcourse surveys were used to assess student perceptions. Most students (∼79%) watched videos for both blended laboratories. Assignment scores did not differ between blended and traditional laboratories (P = 0.62) or between sections (P = 0.91). Practicum scores did not differ between sections (both P > 0.05). At the end of the course, students' perceived value of the blended format increased (P learning key foundational content through video demonstrations before class greatly enhanced their learning of course material compared with a preassigned reading (94% vs. 78%, P Blended exercise physiology laboratories provided an alternative method for delivering content that was favorably perceived by students and did not compromise student performance.

Novel bio-based and biodegradable polymer blends

Science.gov (United States)

Yang, Shengzhe

Most plastic materials, including high performance thermoplastics and thermosets are produced entirely from petroleum-based products. The volatility of the natural oil markets and the increasing cost of petroleum have led to a push to reduce the dependence on petroleum products. Together with an increase in environmental awareness, this has promoted the use of alternative, biorenewable, environmentally-friendly products, such as biomass. The growing interest in replacing petroleum-based products by inexpensive, renewable, natural materials is important for sustainable development into the future and will have a significant impact on the polymer industry and the environment. This thesis involved characterization and development of two series of novel bio-based polymer blends, namely polyhydroxyalkanoate (PHA)/polyamide (PA) and poly(lactic acid) (PLA)/soy protein. Blends with different concentrations and compatible microstructures were prepared using twin-screw extruder. For PHA/PA blends, the poor mechanical properties of PHA improved significantly with an excellent combination of strength, stiffness and toughness by adding PA. Furthermore, the effect of blending on the viscoelastic properties has been investigated using small-amplitude oscillatory shear flow experiments as a function of blend composition and angular frequency. The elastic shear modulus (G‧) and complex viscosity of the blends increased significantly with increasing the concentration of PHA. Blending PLA with soy protein aims at reducing production cost, as well as accelerating the biodegradation rate in soil medium. In this work, the mechanical, thermal and morphological properties of the blends were investigated using dynamic mechanical analysis (DMA), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), and tensile tests.

The growing debate in recent years over how to finance public works through private capital has progressively highlighted the role of project finance (PF) and publicprivate partnerships (PPP) in general. More and more European countries are turning to PF to finance their public infrastructure development. The UK, which pioneered the adoption of project finance in this field, has been followed by Italy, Spain, France, Portugal and Germany and more recently by Greece, Czech Republic and Poland. Beginning in the late 1990's, Italy has steadily amplified its use of PF and PPPs in key sectors such as healthcare as an alternative way of funding the modernisation of its health facilities and hospitals. The trend reveal an average annual growth of 10.9% since 2002 with peaks of varying intensity over the five year period. Project finance and PPPs represent an effective response to the country's infrastructure gap and support the competitiveness of local systems and the quality of public services. None of this will transpire, however without energetic new planning efforts and adequate policy at the centre.

TRENDS IN OFFICIAL DEVELOPMENT ASSISTANCE TO DEVELOPING COUNTRIES AND POSSIBILITIES OF ALTERNATIVE FINANCING MECHANISMS

Full Text Available The study analyses trends in Official Development Assistance (ODA to developing countries, mainly Africa, and possibilities of new financing instruments. Economies of most developing countries, especially those in Sub-Saharan Africa, are characterised by low investment flows, huge import bills and lower exports. Subsequently, development assistance is the major source of external finance and has taken the form of budget support, humanitarian and development finance. However, the noted fall in ODA in 2005, 2009 and 2012 might adversely impact directly on the attainment of millennium development goals in 2015. This negative trend in ODA is a result of a combination of factors such as economic constraints in the donor countries (for example, the debt crisis and/or a new shift in financing mechanisms to developing countries.

2016-03-11

This report provides results from batch-blending test work for remediated nitrate salt (RNS) treatment. Batch blending was identified as a preferred option for blending RNS and unremediated nitrate salt (UNS) material with zeolite to effectively safe the salt/Swheat material identified as ignitable (U.S. Environmental Protection Agency code D001). Blending with zeolite was the preferred remediation option identified in the Options Assessment Report and was originally proposed as the best option for remediation by Clark and Funk in their report, Chemical Reactivity and Recommended Remediation Strategy for Los Alamos Remediated Nitrate Salt (RNS) Wastes, and also found to be a preferred option in the Engineering Options Assessment Report: Nitrate Salt Waste Stream Processing. This test work evaluated equipment and recipe alternatives to achieve effective blending of surrogate waste with zeolite.

Full Text Available The enterprise financial decision is a rational process for option to the optimal variant related to financing and investments. For the capital investment to be justified, the profitability of the invested money must be at least equal with the profitability of the alternative investment opportunities with the same risk on market. The choosing of a way for financing is determined on the one side by their cost and on the other side by the existent capital structure. In this paper I tried to analyse the profitability – risk relationship in the financing decision for the “NIKOS” Ltd.

Nuclear Physicists in Finance

Mattoni, Carlo

2017-01-01

The financial services industry presents an interesting alternative career path for nuclear physicists. Careers in finance typically offer intellectual challenge, a fast pace, high caliber colleagues, merit-based compensation with substantial upside, and an opportunity to deploy skills learned as a physicist. Physicists are employed at a wide range of financial institutions on both the ``buy side'' (hedge fund managers, private equity managers, mutual fund managers, etc.) and the ``sell side'' (investment banks and brokerages). Historically, physicists in finance were primarily ``quants'' tasked with applying stochastic calculus to determine the price of financial derivatives. With the maturation of the field of derivative pricing, physicists in finance today find work in a variety of roles ranging from quantification and management of risk to investment analysis to development of sophisticated software used to price, trade, and risk manage securities. Only a small subset of today's finance careers for physicists require the use of advanced math and practically none provide an opportunity to tinker with an apparatus, yet most nevertheless draw on important skills honed during the training of a nuclear physicist. Intellectually rigorous critical thinking, sophisticated problem solving, an attention to minute detail and an ability to create and test hypotheses based on incomplete information are key to both disciplines.

This report examines the tradeoffs among financing methods for businesses installing onsite photovoltaics (PV). We present case studies of PV financing strategies used by two large commercial retailers that have deployed substantial U.S. PV capacity: IKEA, which owns its PV, and Staples, which purchases power generated from onsite PV systems through power purchase agreements (PPAs). We also analyze the financial considerations that influence any company's choice of PV financing strategy. Our goal in this report is to clarify the financial and institutional costs and benefits of financing strategies and to inform other companies that are considering launching or expanding similar PV programs.

Behavioral finance: Finance with normal people

Directory of Open Access Journals (Sweden)

Meir Statman

2014-06-01

Behavioral finance substitutes normal people for the rational people in standard finance. It substitutes behavioral portfolio theory for mean-variance portfolio theory, and behavioral asset pricing model for the CAPM and other models where expected returns are determined only by risk. Behavioral finance also distinguishes rational markets from hard-to-beat markets in the discussion of efficient markets, a distinction that is often blurred in standard finance, and it examines why so many investors believe that it is easy to beat the market. Moreover, behavioral finance expands the domain of finance beyond portfolios, asset pricing, and market efficiency and is set to continue that expansion while adhering to the scientific rigor introduced by standard finance.

Optimal set of selected uranium enrichments that minimizes blending consequences

Nachlas, J.A.; Kurstedt, H.A. Jr.; Lobber, J.S. Jr.

1977-01-01

Identities, quantities, and costs associated with producing a set of selected enrichments and blending them to provide fuel for existing reactors are investigated using an optimization model constructed with appropriate constraints. Selected enrichments are required for either nuclear reactor fuel standardization or potential uranium enrichment alternatives such as the gas centrifuge. Using a mixed-integer linear program, the model minimizes present worth costs for a 39-product-enrichment reference case. For four ingredients, the marginal blending cost is only 0.18% of the total direct production cost. Natural uranium is not an optimal blending ingredient. Optimal values reappear in most sets of ingredient enrichments

COMPARISON OF STUDENT SATISFACTION BETWEEN TRADITIONAL AND BLENDED TECHNOLOGY COURSE OFFERINGS IN PHYSICAL EDUCATION

2012-01-01

Full Text Available Blended learning With the concerns and dissatisfaction with e-learning, educators are searching for alternative instructional delivery solutions to relieve the above problems. The blended e-learning system has been presented as a promising alternative learning approach. While blended learning has been recognized as having a number of advantages, insufficient learning satisfaction is still an obstacle to its successful adoption. Therefore, the purpose of this study was to evaluate students’ satisfaction with blended learning course delivery compared to a traditional face-to-face class format in a general multimedia course in physical education. Forty six (n=46 undergraduate students, between the ages of 20-22 years old, were randomly assigned into two teaching method groups: Classroom Lecture Instruction (CLI and Blended Lecture Instruction (BLI. For the data collection at the end of this study, students completed an online satisfaction questionnaire.Independent sample t-test analysis was conducted to measure students’ satisfaction towards the CLI and BLI methods. Results indicated that a blended course delivery is preferred over the traditional lecture format. These finding suggest that students' satisfaction could increase when the instructor provides learning environments not only in a traditional classroom, but in an asynchronous online system as well.

Preliminary assessment of blending Hanford tank wastes

Geeting, J.G.H.; Kurath, D.E.

1993-03-01

A parametric study of blending Hanford tank wastes identified possible benefits from blending wastes prior to immobilization as a high level or low level waste form. Track Radioactive Components data were used as the basis for the single-shell tank (SST) waste composition, while analytical data were used for the double-shell tank (DST) composition. Limiting components were determined using the existing feed criteria for the Hanford Waste Vitrification Plant (HWVP) and the Grout Treatment Facility (GTF). Results have shown that blending can significantly increase waste loading and that the baseline quantities of immobilized waste projected for the sludge-wash pretreatment case may have been drastically underestimated, because critical components were not considered. Alternatively, the results suggest further review of the grout feed specifications and the solubility of minor components in HWVP borosilicate glass. Future immobilized waste estimates might be decreased substantially upon a thorough review of the appropriate feed specifications

2006-01-01

Informal finance exists extensively and has been playing an important role in small-and medium-sized enterprise (SME) financing in developing economies,This paper tries to rationalize the extensiveness of informal finance.SME financing suffers more serious information asymmetry to the extent that most SMEs are more opaque and can only provide less collateral.Informal lenders have an advantage over formal financial institutions in collecting "soft information" about SME borrowers.This paper establishes a model including formal and informal lenders and high-and low-risk borrowers with or without sufficient collateral and shows that the credit market in which informal finance is eliminated will allocate funds in some inefficient way,and the efficiency of allocating credit funds can be improved once informal finance is allowed to coexist with formal finance.

Full Text Available This study examined faculty members’ perceptions of blended teaching from several perspectives. A total of 73 faculty members in Turkish Higher Education context participated in the study by completing an online survey that combined quantitative and qualitative approaches. Based on a data analysis, the faculty members’ perceptions were sorted into six categories: (a satisfaction with blended teaching, (b perceived impact on the role of the faculty, (c perceived impact on student learning, (d perceived impact on student motivation, (e advantages of blended teaching, and (f disadvantages of blended teaching. Findings indicated that faculty members were likely to agree that blended teaching provides a high degree of satisfaction and that it requires more time and commitment from the faculty. The faculty members perceived that blended teaching improves student learning and, to some extent, improves motivation. The faculty members also emphasized the importance of institutional support and the use of technology to mitigate student problems. This study presents these faculty members’ perceptions, which are helpful for those planning to implement a blended teaching approach, and makes suggestions for trouble-shooting and taking advantage of the opportunities in a blended environment successfully.

Financing of radioactive waste disposal

Reich, J.

1989-01-01

Waste disposal is modelled as a financial calculus. In this connection the particularity is not primarily the dimension to be expected of financial requirement but above all the uncertainty of financial requirement as well as the ecological, socio-economic and especially also the temporal dimension of the Nuclear Waste Disposal project (disposal of spent fuel elements from light-water reactors with and without reprocessing, decommissioning = safe containment and disposal of nuclear power plants, permanent isolation of radioactive waste from the biosphere, intermediate storage). Based on the above mentioned factors the author analyses alternative approaches of financing or financial planning. He points out the decisive significance of the perception of risks or the evaluation of risks by involved or affected persons - i.e. the social acceptance of planned and designed waste disposal concepts - for the achievement and assessment of alternative solutions. With the help of an acceptance-specific risk measure developed on the basis of a mathematical chaos theory he illustrates, in a model, the social influence on the financing of nuclear waste disposal.

Thermal, mechanical and morphological properties of poly (hydroxybutyrate and polypropylene blends after processing

Directory of Open Access Journals (Sweden)

Wagner Mauricio Pachekoski

2009-06-01

Full Text Available The ever increasing accumulation of plastic waste in the environment has motivated research on polymers that degrade rapidly after being discarded as possible substitutes for conventional inert plastics. Biodegradable polymers can be an alternative, since they have non-toxic residual products and low environmental permanence. Poly (hydroxybutyrate is a biodegradable polymer with a strong potential for industrial purposes, but its thermal instability and fragility limit its applications. Thus, an alternative to improve the processability and properties of poly (hydroxybutyrate is to mix it with another polymer, not necessarily a biodegradable one. In this work, different mixtures of poly(hydroxybutyrate or PHB and polypropylene or PP were extruded and injected. After processing, the blends were studied and their miscibility, mechanical properties and degradability in different soils were analyzed. The main results indicated that the PHB/PP blends had better mechanical properties than pure PHB, as well as improved immiscibility and higher degradation in alkaline soil. The poly-hydroxybutyrate/polypropylene blends showed a tendency for lower crystallinity and stiffness of the polymer matrix, proportional to the amount of polypropylene in the blends, rendering them less stiff and fragile. The degradation tests showed that both pure PHB and blends with 90% PHB and 10% PP were degraded, with loss of their mechanical properties and weight.

Alternative financing methods. Improving regulatory effectiveness in Federal/State siting actions

International Nuclear Information System (INIS)

Evans, D.J.

1977-03-01

This nation has experienced repeated energy crises during the past decade but, in spite of the announcement of grandiose national plans, still does not have an integrated national energy policy. The basic elements of such a policy in simplified form are: development of a common data base; a national fuels policy; electrical need determination (other fuel need determination); plant site and transmission corridor locations; site approval; construction supervision and management of secondary environmental costs; and continuing environmental monitoring of operating plants. The financing of energy planning depends on the assignment of lead responsibility for each element of energy policy making and the intergovernmental relationships involved. Several financial sources are required including Federal general appropriations, state general funds, and applicant fees. The recommended basic financing, however, would flow from a Federal Energy Tax (F.E.T.) coupled with tax credit provisions for state efforts

Exhaust emissions reduction from diesel engine using combined Annona-Eucalyptus oil blends and antioxidant additive

Senthil, R.; Silambarasan, R.; Pranesh, G.

2017-03-01

The limited resources, rising petroleum prices and depletion of fossil fuel have now become a matter of great concern. Hence, there is an urgent need for researchers to find some alternate fuels which are capable of substituting partly or wholly the higher demanded conventional diesel fuel. Lot of research work has been conducted on diesel engine using biodiesel and its blends with diesel as an alternate fuel. Very few works have been done with combination of biodiesel-Eucalypts oil without neat diesel and this leads to lots of scope in this area. The aim of the present study is to analyze the performance and emission characteristics of a single cylinder, direct injection, compression ignition engine using eucalyptus oil-biodiesel as fuel. The presence of eucalyptus oil in the blend reduces the viscosity and improves the volatility of the blends. The methyl ester of Annona oil is blended with eucalypts oil in 10, 20, 30, 40 and 50 %. The performance and emission characteristics are evaluated by operating the engine at different loads. The performance characteristics such as brake thermal efficiency, brake specific fuel consumption and exhaust gas temperature are evaluated. The emission constituents measured are Carbon monoxide (CO), unburned hydrocarbons (HC), Oxides of nitrogen (NOx) and Smoke. It is found that A50-Eu50 (50 Annona + 50 % Eucalyptus oil) blend showed better performance and reduction in exhaust emissions. But, it showed a very marginal increase in NOx emission when compared to that of diesel. Therefore, in order to reduce the NOx emission, antioxidant additive (A-tocopherol acetate) is mixed with Annona-Eucalyptus oil blends in various proportions by which NOx emission is reduced. Hence, A50-Eu50 blend can be used as an alternate fuel for diesel engine without any modifications.

Monte Carlo simulations of the phase separation of a copolymer blend in a thin film

KAUST Repository

Wang, Zhexiao

2014-12-11

Monte Carlo simulations were carried out to study the phase separation of a copolymer blend comprising an alternating copolymer and/or block copolymer in a thin film, and a phase diagram was constructed with a series of composed recipes. The effects of composition and segregation strength on phase separation were discussed in detail. The chain conformation of the block copolymer and alternating copolymer were investigated with changes of the segregation strength. Our simulations revealed that the segment distribution along the copolymer chain and the segregation strength between coarse-grained beads are two important parameters controlling phase separation and chain conformation in thin films of a copolymer blend. A well-controlled phase separation in the copolymer blend can be used to fabricate novel nanostructures.

Full Text Available Globally, blended learning (BL technologies have been increasingly applied in a variety of fields, both public and private sectors. In recent years, universities, public and private businesses and organizations are among those employing blended learning methods and technologies in training and re-training of professionals in the workforce. In Malaysia, the increasing use of blended learning to enhance learning and enriching of soft skills among professionals and individuals in the work place is evident. The advancement of technology is an onset to many new avenues and tool for learning and teaching, and it is the coalescing of these various technologies with particular pedagogy or andragogy has helped to popularize BL. However, when an institution makes the critical choice of delivery methods, it is pertinent that the university needs to consider various success factors. One in particular is student-centered approach that entails the need to understand the students as the beneficiary of learning, and the support system they need to help them learn. This qualitative study reports in detail the experience of a small group of students undertaking Executive Diplomas at Executive Development Centre (EDC, Universiti Utara Malaysia as they progress through their Executive program. This paper looks at learning experiences as described by the learners- it is their story, their experience, and their perspective. This study suggests that BL offered a comfortable middle ground, and has lots of potential in higher education in Malaysia. It is a pedagogical alternative that could play a significant role not only for teaching Business Communication, but has the potential to promote lifelong learning initiatives in Malaysia in a much meaningful and inviting way. Although this study shows that BL contributed a significant and meaningful learning particularly for adult learners, it needs more definitive studies. Such information can be used to guide policy makers

A hybrid multi-criteria decision modeling approach for the best biodiesel blend selection based on ANP-TOPSIS analysis

2015-03-01

Full Text Available The ever increasing demand and depletion of fossil fuels had an adverse impact on environmental pollution. The selection of appropriate source of biodiesel and proper blending of biodiesel plays a major role in alternate energy production. This paper describes an application of hybrid Multi Criteria Decision Making (MCDM technique for the selection of optimum fuel blend in fish oil biodiesel for the IC engine. The proposed model, Analytical Network Process (ANP is integrated with Technique for Order Performance by Similarity to Ideal Solution (TOPSIS and VlseKriterijumska Optimizacija I Kompromisno Resenje (in Serbian (VIKOR to evaluate the optimum blend. Evaluation of suitable blend is based on the exploratory analysis of the performance, emission and combustion parameters of the single cylinder, constant speed direct injection diesel engine at different load conditions. Here the ANP is used to determine the relative weights of the criteria, whereas TOPSIS and VIKOR are used for obtaining the final ranking of alternative blends. An efficient pair-wise comparison process and ranking of alternatives can be achieved for optimum blend selection through the integration of ANP with TOPSIS and VIKOR. The obtained preference order of the blends for ANP-VIKOR and ANP-TOPSIS are B20 > Diesel > B40 > B60 > B80 > B100 and B20 > B40 > Diesel > B60 > B80 > B100 respectively. Hence by comparing both these methods, B20 is selected as the best blend to operate the internal combustion engines. This paper highlights a new insight into MCDM techniques to evaluate the best fuel blend for the decision makers such as engine manufactures and R& D engineers to meet the fuel economy and emission norms to empower the green revolution.

[Dilemmas of health financing].

Science.gov (United States)

Herrera Zárate, M; González Torres, R

1989-01-01

The economic crisis had had a profound effect on the finances of health services in Mexico. The expenditure on health has decreased, both in absolute terms and in relation to the national gross product. Funding problems have been aggravated by inequities in budget distribution: social security institutions have been favored; geographical distribution of resources is concentrated in the central areas of the country and in the more developed states, and curative health care has prevailed over preventive medicine. Administrative inefficiency hinders even more the appropriate utilization of resources. Diversification of funding sources has been proposed, through external debt, local funding, and specific health taxing. But these proposals are questionable. The high cost of the debt service has reduced international credits as a source of financing. Resource concentration at the federal level, and the different compromises related to the economic solidarity pact have also diminished the potentiality of local state financing. On the other hand, a special health tax is not viable within the current fiscal framework. The alternatives are a better budget planning, a change in the institutional and regional distribution of resources, and improvement in the administrative mechanisms of funding.

Use of information and communication technologies (ICT) in the higher education is inevitable. The use of ICT in the educational processes has many advantages and can improve their quality if used appropriately. In recent years, among educators and teachers increased use of blended learning, which is characterized by combining distance learning through digital media with traditional classroom learning (face-to-face learning). This paper presents the results of the use of blended learning in an international, interdisciplinary doctoral summer school Environmental Protection which was held in Ljubljana, Slovenia in the summer of 2016. At the end of May 2017 the consortium of the University of Ljubljana, University of Natural Resources and Life Sciences Vienna, University of Brescia and company Piktorama will organize the second summer school for doctoral students on the topic of Natural Hazards where again blended learning will be used. Furthermore, in the scope of the Second World Open Educational Resources Congress, which will be held in September 2017 under the auspices of UNESCO, the consortium will prepare a roundtable, where participants will discuss and share experiences of using blended learning. The implementation of two doctoral summer schools and workshop is financed by Erasmus+ programme.

In this sixth paper of the Series, we review health-financing reforms in seven countries in southeast Asia that have sought to reduce dependence on out-of-pocket payments, increase pooled health finance, and expand service use as steps towards universal coverage. Laos and Cambodia, both resource-poor countries, have mostly relied on donor-supported health equity funds to reach the poor, and reliable funding and appropriate identification of the eligible poor are two major challenges for nationwide expansion. For Thailand, the Philippines, Indonesia, and Vietnam, social health insurance financed by payroll tax is commonly used for formal sector employees (excluding Malaysia), with varying outcomes in terms of financial protection. Alternative payment methods have different implications for provider behaviour and financial protection. Two alternative approaches for financial protection of the non-poor outside the formal sector have emerged-contributory arrangements and tax-financed schemes-with different abilities to achieve high population coverage rapidly. Fiscal space and mobilisation of payroll contributions are both important in accelerating financial protection. Expanding coverage of good-quality services and ensuring adequate human resources are also important to achieve universal coverage. As health-financing reform is complex, institutional capacity to generate evidence and inform policy is essential and should be strengthened. Copyright © 2011 Elsevier Ltd. All rights reserved.

Characterization of interfaces in Binary and Ternary Polymer Blends by Positron Lifetime Spectroscopy

Science.gov (United States)

Ranganathaiah, C.

2015-06-01

A miscible blend is a single-phase system with compact packing of the polymeric chains/segments due configuration/conformational changes upon blending. Differential Scanning Calorimetry (DSC) is the most employed method to ascertain whether the blend is miscible or immiscible. Positron Lifetime Spectroscopy (PLS) has been employed in recent times to study miscibility properties of polymer blends by monitoring the ortho-Positronium annihilation lifetimes as function of composition. However, just free volume monitoring and the DSC methods fail to provide the composition dependent miscibility of blends. To overcome this limitation, an alternative approach based on hydrodynamic interactions has been developed to derive this information using the same o-Ps lifetime measurements. This has led to the development of a new method of measuring composition dependent miscibility level in binary and ternary polymer blends. Further, the new method also provides interface characteristics for immiscible blends. The interactions between the blend components has a direct bearing on the strength of adhesion at the interface and hence the hydrodynamic interaction. Understanding the characteristic of interfaces which decides the miscibility level of the blend and their end applications is made easy by the present method. The efficacy of the present method is demonstrated for few binary and ternary blends.

The word blend in linguistics means a word formed from two parts of two words. In polymer science polymer blends means polymer mixtures, a class of materials analogues to the metal alloys. Blending of polymers is a simple and economic way to create new materials meeting specific desired properties. The other alternative is to synthesize such materials eventually facing the organic chemistry design difficulties. The low entropy of mixing polymers makes the process thermodynamically unfavorable, unless there are some specific interactions between the mixed polymers. As a result, in thermal equilibrium typically a phase separation between the blend components takes place. The main challenge facing the blending of polymers is the control of the length scale of the phase separation. One of the most important applications, where the control of the phase separation is crucial for the performance is the organic solar cells. In organic solar cells a blend of an electron donating polymer and electron accepting one is formed. The dimensions of the phase separation between the two polymers should be in the range of the exciton diffusion length [1-3] (in semiconductors, exciton diffusion length is the average distance traveled by the electron-hole pair before recombination). Only under this condition the charge transfer at the interface between the two polymer layers can take place and the solar cell performs efficiently. The thin polymer blend layers for such applications are commonly deposited by spin coating from solution containing both polymers. The morphology of the thin layer prepared in this way is highly influenced by the preparation conditions such as the surface properties of the substrate, the solvent from which the blend was deposited, the temperature, and the annealing temperature [4-9]. Therefore controlling the length scale of phase separation in layers casted or spin coated from solutions is difficult and is a matter of trials and errors. Recently a novel

The enterprise financial decision is a rational process for option to the optimal variant related to financing and investments. For the capital investment to be justified, the profitability of the invested money must be at least equal with the profitability of the alternative investment opportunities with the same risk on market. The choosing of a way for financing is determined on the one side by their cost and on the other side by the existent capital structure. In this paper I tried to ana...

Full Text Available Straight vegetable oil (SVO biofuel is a promising alternative to petroleum diesel fuel primarily due to its comparable physical properties to that of petroleum diesel fuel. However, the relatively higher viscosity of SVO limits its direct application in diesel engine. To resolve this issue, binary biofuel blends was introduced in this study to reduce the viscosity of SVO. In this work, a novel biofuel namely Melaleuca Cajuputi oil (MCO was used and blended with refined palm oil (RPO. A total of four blends with the mixing ratios of 20%, 40%, 50% and 60% of MCO were prepared. Various key properties of dynamic viscosity, calorific value and density of the blends were measured and benchmarked against the biodiesel standards based on ASTM D6751. It was found that viscosity and density of the blends decreased with the increase of MCO fraction. Meanwhile, the calorific value of the blends increased linearly as the MCO fraction increased. The blend of 40RPO60MCO was found to have comparable key properties of viscosity, calorific value and density to those of petroleum diesel fuel and ASTM D6751 standard.

Full Text Available The Pongamia and waste cooking oils are the main non edible oils for biodiesel production in India. The aim of the present work is to evaluate the fuel properties and investigate the impact on engine performance using Pongamia and waste cooking biodiesel and their ternary blend with diesel. The investigation of the fuel properties shows that Pongamia biodiesel and waste cooking biodiesel have poor cold flow property. This will lead to starting problem in the engine operation. To overcome this problem the ternary blends of diesel, waste cooking biodiesel and Pongamia biodiesel are prepared. The cloud and pour point for ternary blend, (WCB20:PB20:D60 were found to be 7 °C and 6.5 °C which are comparable to cloud and pour point of diesel 6 °C and 5 °C, respectively. The result of the test showed that brake specific fuel consumption for Pongamia biodiesel and waste cooking biodiesel is higher than ternary blend, (WCB20:PB20:D60 due to their lower energy content. The brake thermal efficiency of ternary blend and diesel is comparable while the Pongamia and waste cooking biodiesel have low efficiency. The result of investigation showed that ternary blend can be developed as alternate fuel.

What physicists should know about finance

Schmidt, Anatoly B.

2005-05-01

There has been growing interest in Econophysics, i.e. analysis and modeling of financial time series using the theoretical Physics concepts (scaling, fractals, chaos). Besides the scientific stimuli, this interest is backed by perception that the financial industry is a viable alternative for those physicists who are not able or are not willing to pursue an academic career. However, the times when any Ph.D. in Physics had a chance to find a job on the Wall Street are gone (if they ever existed). Indeed, not every physicist wields the stochastic calculus, non-normal statistical distributions, and the methods of time series analysis. Moreover, now that many universities offer courses in mathematical finance, the applicants for quantitative positions in finance are expected to know such concepts as option pricing, portfolio management, and risk measurement. Here I describe a synthetic course based on my book [1] that outlines both worlds: Econophysics and Mathematical Finance. The course may be offered as elective for senior undergraduate or graduate Physics majors.

Alonso, Gustavo; Palacios, Javier C.; Ramirez, Jose R.; Longoria, Luis C.; Valle, Edmundo del

2011-01-01

Nuclear power deployment requires an extensive capital investment that in many cases prevents the addition of new units for single private companies. The deployment of a single unit of 1000 MWe with the current economical cost requires around 5 billion US dollars assuming no delays or unforeseen problems. In Mexico the electricity is produced by the government utility 'Comision Federal de Electridad' with 47 GWe of installed capacity thereby it can afford this kind of investment. Here we assess two financing scenarios for deployment of a single nuclear reactor unit, in the first one the utility will use their own resources and in the second the nuclear power plant will be built using international and national credits, comparisons of these two scenarios are presented.

2013-09-01

Full Text Available Biodiesel produced from vegetable oils, animal fats and algae oil is a renewable, environmentally friendly and clean alternative fuel that reduces pollutants and greenhouse gas emissions in marine applications. This study investigates the influence of biodiesel blend on the characteristics of residual and distillate marine fuels. Adequate correlation equations are applied to calculate the fuel properties of the blended marine fuels with biodiesel. Residual marine fuel RMA has inferior fuel characteristics compared with distillate marine fuel DMA and biodiesel. The flash point of marine fuel RMA could be increased by 20% if blended with 20 vol% biodiesel. The sulfur content of residual marine fuel could meet the requirement of the 2008 MARPOL Annex VI Amendment by blending it with 23.0 vol% biodiesel. In addition, the kinematic viscosity of residual marine fuel could be reduced by 12.9% and the carbon residue by 23.6% if 20 vol% and 25 vol% biodiesel are used, respectively. Residual marine fuel blended with 20 vol% biodiesel decreases its lower heating value by 1.9%. Moreover, the fuel properties of residual marine fuel are found to improve more significantly with biodiesel blending than those of distillate marine fuel.

Financing Preference Behaviour for Private Finance Initiative (PFI Projects

Directory of Open Access Journals (Sweden)

Yati Md Lasa

2016-01-01

Full Text Available Project Financing Initiative (PFI projects require the private sector to invest an enormous amount of capital for the development of public projects. The private sector has to seek cost-effective financing sources for their survival in the long-term concession. Conventional financing uses widely; however, Islamic financing promises better financing through profit and loss sharing. This paper reviews financing preferences for PFI projects and the factors influencing the choice of funding. The results show that religious perspective, quality of services, financing facilities and reputation are the factors that are expected will influence the financing preference behaviour, either Islamic or conventional finance.

A fuzzy logic approach toward solving the analytic enigma of health system financing.

Chernichovsky, Dov; Bolotin, Arkady; de Leeuw, David

2003-09-01

Improved health, equity, macroeconomic efficiency, efficient provision of care, and client satisfaction are the common goals of any health system. The relative significance of these goals varies, however, across nations, communities and with time. As for health care finance, the attainment of these goals under varying circumstances involves alternative policy options for each of the following elements: sources of finance, allocation of finance, payment to providers, and public-private mix. The intricate set of multiple goals, elements and policy options defies human reasoning, and, hence, hinders effective policymaking. Indeed, "health system finance" is not amenable to a clear set of structural relationships. Neither is there a universe that can be subject to statistical scrutiny: each health system is unique. "Fuzzy logic" models human reasoning by managing "expert knowledge" close to the way it is handled by human language. It is used here for guiding policy making by a systematic analysis of health system finance. Assuming equal welfare weights for alternative goals and mutually exclusive policy options under each health-financing element, the exploratory model we present here suggests that a German-type health system is best. Other solutions depend on the welfare weights for system goals and mixes of policy options.

Financing gas plants using off balance sheet structures

International Nuclear Information System (INIS)

Best, R.J.; Malcolm, V.

1999-01-01

A means by which to finance oil and gas facilities using off balance sheet structures was presented. Off balance sheet facility financing means the sale by an oil and gas producer of a processing and/or transportation facility to a financial intermediary, who under a Management Agreement, appoints the producer as the operator of the facility. The financial intermediary charges a fixed processing fee to the producer and all the benefits and upside of ownership are retained by the producer. This paper deals specifically with a flexible off balance sheet facility financing structure that can be used to make effective use of discretionary capital which is committed to gas processing and to the construction of new gas processing facilities. Off balance sheet financing is an attractive alternative method of ownership that frees up capital that is locked into the facilities while allowing the producer to retain strategic control of the processing facility

Alternate aviation fuels for military or commercial use are required to satisfy MIL-DTL-83133F(2008) or ASTM D 7566 (2010) standards, respectively, and are classified as drop-in fuel replacements. To satisfy legacy issues, blends to 50% alternate fuel with petroleum fuels are certified individually on the basis of feedstock. Adherence to alternate fuels and fuel blends requires smart fueling systems or advanced fuel-flexible systems, including combustors and engines without significant sacrifice in performance or emissions requirements. This paper provides preliminary performance (Part A) and emissions and particulates (Part B) combustor sector data for synthetic-parafinic-kerosene- (SPK-) type fuel and blends with JP-8+100 relative to JP-8+100 as baseline fueling.

In this work, Waste Plastic Pyrolysis oil (WPPO), Ethanol, Diesel blend with Cetane additive has been attempted as an alternative fuel. A Twin cylinder, Direct Injection engine was used to assess the engine performance and emission characteristics of waste plastic pyrolysis oil with cetane additive. Experimental results of blended plastic fuel and diesel fuel were compared.

Real world financing opportunities for energy conservation projects

Tramonte, D.J.

1988-01-01

Do you have the resources, dollars, people expertise and general know-how to do all the energy conservation measures. If you have the funds, do it yourself. Historically you would save more if you hired a private concern because that is the only job the contractor does for you. You have other hats to wear and fires to put out. Using third-party financing can be a good decision based on your specific needs. Procrastination is not the answer - the cost of delay is extensive. Financing energy conservation measures is no different from financing your automobile or home. If the benefits outweigh the negatives, the answer is obvious. Remember, in any case of using private sector financing, your are joining a partnership arrangement. The only way to succeed is to be honest with each other on the front end. There need not be any surprises. Any reputable company will gladly have your attorney evaluate all agreements, amortization schedules, and attachments. Real world financing alternatives will continue to change as the market matures. It's not too good to be true. It is no more than a vehicle to make the efforts of capital improvements streamlined. The money or financing is the catalyst to the project and makes the other areas meld.

Blending Biodiesel in Fishing Boat Fuels for Improved Fuel Characteristics

International Nuclear Information System (INIS)

Lin, Cherng-Yuan

2014-01-01

Biodiesel is a renewable, clean, alternative energy source with advantages, such as excellent lubricity, superior biodegradability, and high combustion efficiency. Biodiesel is considered for mixing with fishing boat fuels to adjust their fuel characteristics so that toxic pollutants and greenhouse-effect gas emissions from such shipping might be reduced. The effects of blending fishing boat fuels A and B with various weight proportions of biodiesel are experimentally investigated in this study. The results show that biodiesel blending can significantly improve the inferior fuel properties of both fishing boat fuels and particularly fuel B. The flash points of both of these fuels increases significantly with the addition of biodiesel and thus enhances the safety of transporting and storing these blended fuels. The flash point of fishing boat fuel B even increases by 16% if 25 wt.% biodiesel is blended. The blending of biodiesel with no sulfur content is found to be one of the most effective ways to reduce the high sulfur content of fishing boat fuel, resulting in a reduction in the emission of sulfur oxides. The addition of only 25 wt.% biodiesel decreased the sulfur content of the fishing boat fuel by 37%. The high kinematic viscosity of fishing boat fuel B was also observed to be reduced by 63% with the blending of just 25 wt.% biodiesel. However, biodiesel blending caused a slight decrease in heating value around 1–4.5%.

Full Text Available Musharakah Tijarah Cross-Border Financing (“Product” is the product to enable the Bank to undertake project and contract cross-border financing activities or other identified business ventures on “pure” Joint Venture basis, using the underlying Islamic financing contract of Musharakah. Musharakah concept has a low market share of less than 2.5% in the overall existing Islamic financing products in Malaysia. This product encourages mobilization of idle capital / cash entities and thus provides a basis for economic cooperation between these organizations in the society. The product also is expected to inject greater prosper to the Bank’s overall performance and ultimately able to assist small time landowners in a big way through business risk sharing. Musharakah provides an alternative investment, which will cater for Islamic investors and partners, especially from GCC, who may have been reluctant to invest in conventional or current debt-based financing scheme. With Musharakah concept, the most preferred and globally accepted Islamic financing, this can attract these investors to participate on similar risk-sharing arrangements through the creation of Specific Investment Account (SIA or Islamic Syndication to back financing made into the Joint Venture.

Blended learning has been coupled with different epistemological understandings and learning theories, but the fundamental character and dimensions of learning...... in blended learning are still insufficient. Moreover, blended learning is a misleading concept described as learning, despite the fact that it fundamentally is an instructional and didactic approach (Oliver & Trigwell, 2005) addressing the learning environment (Inglis, Palipoana, Trenhom & Ward, 2011......) instead of the learning processes behind.

Full Text Available Petroleum based fuels worldwide have not only resulted in the rapid depletion of conventional energy sources, but have also caused severe air pollution. The search for an alternate fuel has led to many findings due to which a wide variety of alternative fuels are available at our disposal now. The existing studies have revealed the use of vegetable oils for engines as an alternative for diesel fuel. However, there is a limitation in using straight vegetable oils in diesel engines due to their high viscosity and low volatility. In the present work, neat mango seed oil is converted into their respective methyl ester through transesterification process. Experiments are conducted using various blends of methyl ester of mango seed oil with diesel in a single cylinder, four stroke vertical and air cooled Kirloskar diesel engine. The experimental results of this study showed that the MEMSO biodiesel has similar characteristics to those of diesel. The brake thermal efficiency, unburned hydrocarbon and smoke density are observed to be lower in case of MEMSO biodiesel blends than diesel. The CO emission for B25, B50 and B75 is observed to be lower than diesel at full load, whereas for B100 it is higher at all loads. On the other hand, BSFC and NOx of MEMSO biodiesel blends are found to be higher than diesel. It is found that the combustion characteristics of all blends of methyl ester of mango seed oil showed similar trends with those of the baseline diesel. From this study, it is concluded that optimized blend is B25 and could be used as a viable alternative fuel in a single cylinder direct injection diesel engine without any modifications.

Small Business Tax Evasion, is There a Case of Internal Finance?

Directory of Open Access Journals (Sweden)

Ilirjan Lipi

2017-04-01

Full Text Available As long as there are taxes, the incentive for evasion will exist as well. Studies for tax evasion are of interest in different fields like that of economics, public finance, personal finance, business administration, business finance, financial accounting, in the banking system etc. However, there are only a few studies about the internal causes and financial incentives that oblige decision-makers of small firms towards tax evasion. When we refer to business tax evasion, always brings to mind sensational cases of large businesses that evade taxes, but business tax evasion is a widespread phenomenon even to small firms. To be more competitive, small business must have a consistently entrepreneurial orientation, but limited financing prevents this, therefore the business savings from tax evasion is believed to be an internally funding path. The restrictions on small firms financing often make them orientate more toward internal generation of funds, which also has few alternatives. As a way to internal saving, firms often find tax evasion, which is not only a deviant and unethical behavior, but also puts firms into many difficulties in the long run. Consequently, the study aims to discuss the phenomenon of tax evasion in the managerial practice of small business in an Albanian region, as well as its financial cause as is perceived by the small business. The study findings report that the deviant behavior of businesses from taxes considers the need for internal financing as an important reason. The study concluded that savings from tax evasion is an alternative of internal financing primarily for small and early-staged firms, and that if entrepreneurs are capable of a good business model and competitive strategy, they will not need to make evasion.

An experimental evaluation of using jojoba oil as an alternate diesel engine fuel has been conducted in the present work. Measurements of jojoba oil chemical and physical properties have indicated a good potential of using jojoba oil as an alternative diesel engine fuel. Blending of jojoba oil with gas oil has been shown to be an effective method to reduce engine problems associated with the high viscosity of jojoba oil. Experimental measurements of different performance parameters of a single cylinder, naturally aspirated, direct injection, diesel engine have been performed using gas oil and blends of gas oil with jojoba oil. Measurements of engine performance parameters at different load conditions over the engine speed range have generally indicated a negligible loss of engine power, a slight increase in brake specific fuel consumption and a reduction in engine NO{sub x} and soot emission using blends of jojoba oil with gas oil as compared to gas oil. The reduction in engine soot emission has been observed to increase with the increase of jojoba oil percentage in the fuel blend. (Author)

Full Text Available The structuring and financing of mergers and acquisitions has substantial tax consequences. The decision to acquire the assets or the shares of the target company should take into consideration, on one hand, the capital gains taxation at the transaction time and, on the other hand, the tax planning opportunities for the future. The tax burden can also be minimized by an optimum selection of the acquisition vehicle. The choice of a financing alternative should take into account the interest deductibility and the specific tax regulations of each jurisdiction concerned.

Full Text Available Rural tourism and agricultural tourism are activities, which generate alternative incomes, a fact that offers development possibilities to the rural space, due to the unique landscapes, large semi-natural areas, the inhabitants' born hospitality in the rural surroundings. From this perspective, a modernization, development and innovation process for the Romanian rural tourism is required. All these aspects, however, require financing. Therefore, a pre-accession financing source of the rural tourism was the SAPARD programme, a programme which "offered the opportunity" to many business people to start their business in this field. The paper shows the evolution of the rural boarding houses between 2003-2007, with analyses on the number, type of financing, development region.

This study presents a novel empirical approach to identify financing constraints for innovation based on the idea of an ideal test as suggested by Hall (2008). Firms were offered a hypothetical payment and were asked to choose between alternatives of use. If they choose additional innovation projects they must have had some unexploited investment opportunities that were not profitable using more costly external finance. That is, these firms have been financially constrained. We attribute cons...

The use of hydrogen blended with natural gas is a viable alternative to pure fossil fuels because of the expected reduction of the total pollutant emissions and increase of efficiency. These blends offer a valid opportunity for tackling sustainable transportation, in view of the future stringent emission limits for road vehicles. The aim of the present paper is the investigation of the performance of internal combustion engines fuelled by such blends. A numerical investigation on the characteristics of natural gas-hydrogen blends as well as their effect on engine performance is carried out. The activity is focused on the influence of such blends on flame propagation speed. Combustion pattern modelling allows the comparison of engine brake efficiency and power output using different fuels. Results showed that there is an increase in engine efficiency only if Maximum Brake Torque (MBT) spark advance is used for each fuel. Moreover, an economic analysis has been carried out to determine the over cost of hydrogen in such blends, showing percent increments by using these fuels about between 10 and 34%. (author)

Resource consequences of reenrichment versus blending

Owen, P.S.

1981-01-01

Many recent studies, including INFCE and NASAP, have concluded that recycling thermal reactor fuel reduces natural uranium requirements. These studies are based on a common set of assumptions concerning the method of recycling uranium, and consequently have produced quite similar results. It was assumed, however, that the residual uranium would be reenriched rather than blended with higher enriched uranium. This paper will examine several possible alternatives to reenriching residual uranium and discuss the consequences of each

Crude Palm Oil (CPO) is renewable bio-based resource. It is an attractive alternative fuel which provides the potential to reduce emission problems. CPO is an example of biofuels that can be blended with petroleum distillates as a fuel in mobile engines and industrial processes to help offset the increasing energy demand. This paper highlights the results of blended Crude Palm Oil (CPO)/Medium Fuel Oil (MFO) as an alternative environmentally friendly boiler's fuel. Heating values of the blend fuels have been measured using an oxygen bomb calorimeter. Combustion performance of a blend containing 50% CPO in MFO fuel was examined using a commercial boiler. The blend burned satisfactorily without major modification to the appliance and fuel delivery system. SO 2 emissions were 51.67% lower than MFO, H 2 S decreased about 55.61% while NO x were 18.67% reduced. Results indicate potential reductions of SO 2 , H 2 S and NO x , and greenhouse gas emissions for the petroleum distillates can be replaced with this blend. (author)

2008-01-01

In recent years financing through the creation of an independent project company or financing by non-recourse debt has become an important part of corporate decisions. Shah and Thakor (JET, 1987) argue that project financing can be optimal when asymmetric information exists between firm's insiders and market participants. In contrast to that paper, we provide an asymmetric information argument for project financing without relying on corporate taxes, costly information production or an assump...

Renewable energy finance and project ownership. The impact of alternative development structures on the cost of wind power

International Nuclear Information System (INIS)

Wiser, R.H.

1997-01-01

This paper uses traditional financial cash flow techniques to examine the impact of different ownership and financing structures on the cost of renewable energy, specifically wind power. Most large, non-hydroelectric, renewable energy projects are developed, owned and financed by private non-utility generators. Recently, however, US utilities have begun to consider owning and financing their own wind power facilities rather than purchasing power from independent renewable energy suppliers. Utilities in other countries have also expressed interest in direct renewable energy investments. A primary justification for utility ownership of wind turbine power plants is that utility self-financing and ownership is cheaper than purchasing wind energy from non-utility renewable energy suppliers. The results presented in this paper support that justification, although some of the estimated cost savings associated with utility ownership are a result of suboptimal utility analysis procedures and implicit risk shifting. Financing terms and variables are shown to significantly impact wind power costs. (author)

2011-01-01

Nuclear power deployment requires an extensive capital investment that in many cases prevents the addition of new units for single private companies. The deployment of a single unit of 1000 MWe with the current economical cost requires around 5 billion US dollars assuming no delays or unforeseen problems. In Mexico the electricity is produced by the government utility 'Comision Federal de Electridad' with 47 GWe of installed capacity thereby it can afford this kind of investment. Here we assess two financing scenarios for deployment of a single nuclear reactor unit, in the first one the utility will use their own resources and in the second the nuclear power plant will be built using international and national credits, comparisons of these two scenarios are presented.

2018-06-01

Full Text Available The core object of this study is to examine the suitability of linseeds for biodiesel production. The performance of an engine at different proportions of linseed blends with petro-diesel and the amount of emissions rate were investigated. Initially, linseed biodiesel was produced through transesterification process, and then it was mixed with petro-diesel fuel (D100 blends at volumetric ratios of 10% (LB10, 20% (LB20, and 30% (LB30. The properties of linseed biodiesel and its blends were investigated and compared with petro-diesel properties with reference to ASTM standards. It has been observed that the fuel properties of produced biodiesel are within ASTM permissible limits. The specific fuel consumption (SFC of LB10 blend has been found lesser compared to LB20 and LB30. SFC of D100 is slightly less than that of all the blends. The brake thermal efficiency (BTE of LB30 is greater than that of pure diesel D100 at maximum load and greater than that of LB10 and LB20. The heat dissipation rate in all linseed blends is found to have been less than that of D100. Carbon monoxide, carbon dioxide and NOx emissions of linseed blends are mostly lower in comparison with D100’s. Among all blends, LB10 was found more suitable alternative fuel for diesel engines and can be blended with petro diesel without engine modifications. It can be concluded that cultivation and production of linseed in Pakistan is very promising, therefore, it is recommended that proper exploitation and use of linseed for energy production may be encouraged through pertinent agencies of Pakistan.

In order to meet rapidly growing demand for fuel, as well as address environmental concerns, the aviation industry has been testing alternate fuels for performance and technical usability in commercial and military aircraft. In order to make alternate fuels (and blends) a viable option for aviation, the fuel must be able to perform at a similar or higher level than traditional petroleum fuel. They also attempt to curb harmful emissions, and therefore a truly effective alternate fuel would emit at or under the level of currently used fuel. This report analyzes data from gaseous and particulate emissions of an aircraft combustor sector. The data were evaluated at various inlet conditions, including variation in pressure and temperature, fuel-to-air ratios, and percent composition of alternate fuel. Traditional JP-8+100 data were taken as a baseline, and blends of JP-8+100 with synthetic-paraffinic-kerosene (SPK) fuel (Fischer-Tropsch (FT)) were used for comparison. Gaseous and particulate emissions, as well as flame luminosity, were assessed for differences between FT composition of 0, 50, and 100 percent. The data show that SPK fuel (an FT-derived fuel) had slightly lower harmful gaseous emissions, and smoke number information corroborated the hypothesis that SPK-FT fuels are cleaner burning fuels.

Oxidative stability of biodiesel blends derived from waste frying oils

Full Text Available The high cost of biodiesel production is mainly linked to the price of raw material.This factor has favored the use of alternative fats and oils such as those used in frying. Since biodiesel can be obtained from several vegetable and animal raw materials, the physicochemical characteristics of the fuel may vary considerably. One of these characteristics is the fatty acid composition. It directly affects the oxidative stability of biodiesel, which can be impaired when the fuel undergoes exposure to sunlight, metals, oxygen and high temperatures. In order to improve the oxidative stability of biodiesels produced from waste frying oil some studies involving blends of different raw materials have been carried out. In this sense, this work aimed to assess the characteristics resulting from the blending of soybean waste frying oil with other waste biodiesels in what concerns to oxidation. The blends of fatty materials were obtained by means of a 2² factorial design. The induction periods of biodiesel blends were enough to meet the ASTM D6751 standard. Swine fat was responsible for the increase in the induction period values.

Overcoming barriers to wind project finance in Australia

International Nuclear Information System (INIS)

Kann, Shayle

2009-01-01

The wind power industry in Australia is expected to grow rapidly over the next decade, primarily due to a forthcoming expanded national renewable energy target (RET) which will mandate that renewable sources provide approximately 20% of Australia's electricity production by 2020. However, development of new wind generation in Australia has stalled as a result of several barriers to project finance, the mechanism through which most wind farms have been developed historically. This paper provides an overview of wind power financing in Australia in light of recent political and financial trends. Drawing upon existing literature and a series of stakeholder interviews, it identifies three primary barriers to project finance: regulatory risk surrounding legislation of the RET, semi-privatization of electricity retailers in New South Wales, and limited capital availability resulting from the recent global credit crisis. The paper concludes that the confluence of these barriers limits the availability of long-term contracts that provide revenue certainty for pre-construction wind projects, while simultaneously making these contracts a necessity in order to obtain project finance. In an attempt to mitigate these effects, this paper identifies four alternative development strategies that can be pursued.

RISK OF PROFIT LOSS SHARING FINANCING: THE CASE OF INDONESIA

2016-02-01

Full Text Available This study analyzes the risk of profit-and-loss sharing finance in Indonesian Islamic banking. Data used is secondary data obtained from the Financial Services Authority’s 2009-2014 publication. Financing risk is measured by risk return and opportunity cost. Results of the study show that risk return in mudharaba financing is more volatile than that in musharaka as it is potentially driven by agency problems. In all groups of banks, higher incomes are more promising in mudharaba than musharaka; but individually musharaka is more attractive to Islamic Rural Bank groups, and vice versa for the Sharia Bank groups. The one side it is more secure for Islamic banking to allocate funds in musharaka contract, which is an alternative to murabaha. However, musharaka contract is less attractive due to lower potential returns. Although high returns are more promising in mudaraba, this financing mode has higher risk of returns.DOI: 10.15408/aiq.v8i1.1793

Combustion and emission characteristics of diesel engine fuelled with rice bran oil methyl ester and its diesel blends

Directory of Open Access Journals (Sweden)

Gattamaneni Rao Narayana Lakshmi

2008-01-01

Full Text Available There has been a worldwide interest in searching for alternatives to petroleum-derived fuels due to their depletion as well as due to the concern for the environment. Vegetable oils have capability to solve this problem because they are renewable and lead to reduction in environmental pollution. The direct use of vegetable oils as a diesel engine fuel is possible but not preferable because of their extremely higher viscosity, strong tendency to polymerize and bad cold start properties. On the other hand, Biodiesels, which are derived from vegetable oils, have been recently recognized as a potential alternative to diesel oil. This study deals with the analysis of rice bran oil methyl ester (RBME as a diesel fuel. RBME is derived through the transesterification process, in which the rice bran oil reacts with methanol in the presence of KOH. The properties of RBME thus obtained are comparable with ASTM biodiesel standards. Tests are conducted on a 4.4 kW, single-cylinder, naturally aspirated, direct-injection air-cooled stationary diesel engine to evaluate the feasibility of RBME and its diesel blends as alternate fuels. The ignition delay and peak heat release for RBME and its diesel blends are found to be lower than that of diesel and the ignition delay decreases with increase in RBME in the blend. Maximum heat release is found to occur earlier for RBME and its diesel blends than diesel. As the amount of RBME in the blend increases the HC, CO, and soot concentrations in the exhaust decreased when compared to mineral diesel. The NOx emissions of the RBME and its diesel blends are noted to be slightly higher than that of diesel.

An Experimental Investigation of Ethanol-Diesel Blends on Performance and Exhaust Emissions of Diesel Engines

Directory of Open Access Journals (Sweden)

Tarkan Sandalcı

2014-08-01

Full Text Available Ethanol is a promising alternative fuel, due to its renewable biobased origin. Also, it has lower carbon content than diesel fuel and it is oxygenated. For this reason, ethanol is providing remarkable potential to reduce particulate emulsions in compression-ignition engines. In this study, performance of ethanol-diesel blends has been investigated experimentally. Tested fuels were mineral diesel fuel (E0D100, 15% (v/v ethanol/diesel fuel blend (E15D85, and 30% (v/v ethanol/diesel fuel blend (E30D70. Firstly, the solubility of ethanol and diesel was experienced. Engine tests were carried out to reveal the performance and emissions of the engine fuelled with the blends. Full load operating conditions at various engine speeds were investigated. Engine brake torque, brake power, brake specific fuel consumption, brake thermal efficiency, exhaust gas temperature, and finally exhaust emissions were measured. Performance of the tested engine decreased substantially while improvement on smoke and gaseous emissions makes ethanol blend favorable.

Project financing

International Nuclear Information System (INIS)

Cowan, A.

1998-01-01

Project financing was defined ('where a lender to a specific project has recourse only to the cash flow and assets of that project for repayment and security respectively') and its attributes were described. Project financing was said to be particularly well suited to power, pipeline, mining, telecommunications, petro-chemicals, road construction, and oil and gas projects, i.e. large infrastructure projects that are difficult to fund on-balance sheet, where the risk profile of a project does not fit the corporation's risk appetite, or where higher leverage is required. Sources of project financing were identified. The need to analyze and mitigate risks, and being aware that lenders always take a conservative view and gravitate towards the lowest common denominator, were considered the key to success in obtaining project financing funds. TransAlta Corporation's project financing experiences were used to illustrate the potential of this source of financing

Facile fabrication of HDPE-g-MA/nanodiamond nanocomposites via one-step reactive blending.

Song, Ping'an; Yu, Youming; Wu, Qiang; Fu, Shenyuan

2012-06-29

In this letter, nanocomposites based on maleic anhydride grafted high density polyethylene (HDPE-g-MA) and amine-functionalized nanodiamond (ND) were fabricated via one-step reactive melt-blending, generating a homogeneous dispersion of ND, as evidenced by transmission electron microscope observations. Thermal analysis results suggest that addition of ND does not affect significantly thermal stability of polymer matrix in nitrogen. However, it was interestingly found that incorporating pure ND decreases the thermal oxidation degradation stability temperature, but blending amino-functionalized ND via reactive processing significantly enhances it of HDPE in air condition. Most importantly, cone tests revealed that both ND additives and reactive blending greatly reduce the heat release rate of HDPE. The results suggest that ND has a potential application as flame retardant alternative for polymers. Tensile results show that adding ND considerably enhances Young's modulus, and reactive blending leads to further improvement in Young's modulus while hardly reducing the elongation at break of HDPE.

NGOs' Active Roles in the Process of Using Mudaraba as Financing Model in Interest-free Banking

Directory of Open Access Journals (Sweden)

M. Salih KUMAŞ

2016-04-01

Full Text Available Today, it is commonly accepted fact that conventional banking fails in the fair distribution of economic wealth and in the provision of sustainable economic development. It seems almost impossible for Islamic Banking to be a strong alternative to interest-based banking with its current practice.  That is the reason why the alternative financing methods of Islamic Finance should be improved. In this context, the major obstacle for Islamic Banking to be an alternative to conventional counterpart is that it confines itself to murâbaha financing. Although the Mudaraba financing model suits better to the spirit of Islamic Banking and its historic advancement, it is observed that it is nearly not practiced or cannot be practiced. The reason behind this and major problem of Mudaraba model is having lack of enough entrepreneurs and not being able to raise them. In this sense, we believe that NGOs like MUSIAD and ASKON can contribute for the enhancement of the Islamic Banking as we have witnessed that many NGOs had considerable contributions by taking important roles in the past. This process which sort of means the integration of NGOs and Islamic Banking can be carried out in three stages.

In today's scenario cement-concrete has become the backbone of infrastructure development. The use of concrete is increasing day by day and so does cement. One of the major concerns is that the cement manufacturing contributes 7% of total man-made CO2 emission in the environment. At the same time India being a developing country secured the second position in cement production. On the other hand solid waste management is one of the growing problems in India. As we are one of the major contributors in this situation so, the time has come to think about the sustainable alternatives. From various researches it has been observed that the low clinker cement can be suitable option. In the present paper we have tried to develop a low clinker ternary blend for Indian cement industry using the concept of synergetic behavior of fly ash-limestone reaction and formation of more stable monocarboaluminate hydrate and hemicarboaluminate hydrate. 30% fly ash and 15% limestone and 5% gypsum have been used as supplementary cementing material for replacing 50% clinker. The mechanical properties like, compressive strength, have been studied for the fly ash limestone ternary blends cements and the results have been compared with the other controlled blends and ternary blends. The effect of intergrinding of constituent materials has shown a comparable properties which can be used for various structural application. The effect of dolomitic limestone has also been studied in fly ash limestone ternary blends and the result shows the relation between compressive strength and dolomite content is inversely proportional.

[Financing problems of capital goods: part 1: leasing as a solution?].

Science.gov (United States)

Clausen, C C; Bauer, M; Saleh, A; Picker, O

2008-06-01

The provision of financial support of hospitals by States for buying capital goods is becoming increasingly more limited. In order to still make investments, alternative forms of financing such as leasing must be considered in hospitals. However, the change from the classical form of dual financing and the decision to opt for a leasing model involves much more than just a question of costs. Leasing results in easily manageable expenditure, flexibility and adaptability for the choice of model but the leasing installments must be directly financed by the turnover from diagnosis-related groups and so lead to a reduction in the annual profit. In this article the authors try to give the reader an overview of the complex and sometimes counter-productive effect of financial instruments for investments in hospitals using leasing financing as an example. In the follow-up article the decision-making procedure using dynamic investment calculations will be demonstrated using a concrete example.

Integrating Photovoltaic Systems into Low-Income Housing Developments: A Case Study on the Creation of a New Residential Financing Model and Low-Income Resident Job Training Program, September 2011 (Brochure)

This case study covers the process of successfully integrating photovoltaic (PV) systems into a low-income housing development in northeast Denver, Colorado, focusing specifically on a new financing model and job training. The Northeast Denver Housing Center (NDHC), working in cooperation with Del Norte Neighborhood Development Corporation, Groundwork Denver, and the National Renewable Energy Laboratory (NREL), was able to finance the PV system installations by blending private equity funding with utility rebates, federal tax credits, and public sector funding. A grant provided by the Governor's Energy Office allowed for the creation of the new financing model. In addition, the program incorporated an innovative low-income job training program and an energy conservation incentive program.

2014-10-01

Full Text Available In recent 10 years biodiesel fuel was studied extensively as an alternative fuel. Most of researchers reported performance and emission of biodiesel and their blends with constant compression ratio. Also all the research was conducted with use of single biodiesel and its blend. Few reports are observed with the use of variable compression ratio and blends of more than one biodiesel. Main aim of the present study is to analyse the effect of compression ratio on the performance and emission of dual blends of biodiesel. In the present study Blends of Jatropha and Karanja with Diesel fuel was tested on single cylinder VCR DI diesel engine for compression ratio 16 and 18. High density of biodiesel fuel causes longer delay period for Jatropha fuel was observed compare with Karanja fuel. However blending of two biodiesel K20J40D results in to low mean gas temperature which is the main reason for low NOx emission.

Effective utilization of B20 blend with diethyl ether and ethanol as oxygenated additives

Directory of Open Access Journals (Sweden)

Upadrasta-Satya Vara-Prasad

2011-01-01

Full Text Available In the recent times' fatty acid methyl ester popularly called as biodiesel has become more prominent alternate fuel for compression ignition engines based on a single fuel concept. Since, use of neat biodiesel on a large scale is raising certain difficulties and is being adopted in a blended form with petro-diesel fuel and B20 blend has become standardized. However, the HC and NOx emissions of B20 are still on the higher side. Present work aims at experimental evaluation of a single cylinder water-cooled diesel engine by adopting various proportions of ethanol and diethyl ether blends in order to improve performance and emission characteristics of B20 blend. Besides employing different amounts of ethanol and diethyl ether, simultaneous influence of injector nozzle hole size and fuel injection pressure are also investigated to arrive at an optimum configuration. Brake specific fuel consumption and hydrocarbon emissions values are lower with B20 and DEE 5 whereas B20 with DEE15 yielded lower NOx emissions. It is observed that addition of oxygenates have improved the combustion process and lower emissions are obtained. The present investigation revealed that blends with oxygenated additives having higher Cetane rating are superior to neat blend.

Analysing farmer knowledge of the requirements of finance providers can provide valuable insights to policy makers about ways to improve farmers' access to finance. This study compares farmer knowledge of the requirements to obtain finance with the actual requirements set by different finance provider types, and investigates the relation between demographic and socioeconomic factors and farmer knowledge of finance requirements. We use a structured questionnaire to collect data from a sample of finance providers and farmers in Java Island, Indonesia. We find that the most important requirements to acquire finance vary among different finance provider types. We also find that farmers generally have little knowledge of the requirements, which are important to each type of finance provider. Awareness campaigns are needed to increase farmer knowledge of the diversity of requirements among the finance provider types.

LEASING ARRANGEMENTS AS A FORM OF FINANCING BUSINESS ENTITIES IN REPUBLIC OF MACEDONIA

Directory of Open Access Journals (Sweden)

DRAGICA ODZAKLIESKA

2015-03-01

Full Text Available In the modern conditions for working, the problems with providing appropriate sources for financing business entities are more emphasized. In fact, the access to the financing sources is one of the limiting factors for the business entities development. If the business entity is able to satisfy completely or on a higher degree its financing needs from its own sources, then it gains significant competitive advantage and possibility for growth, by decreasing the costs for financing and minimizing the risk. But, these sources most often are not sufficient for business financing. In R. Macedonia, most usually used sources for work financing are the bank loans, which is a result mainly to the nonsufficiently developed financial market, and generally, the low degree of the economic development. However, the bank loans are expensive source of financing, which is negatively reflected into the financial result of the business entities. Because of that, the business entities get down to use alternative financing sources, such as: portfolio investments, foreign direct investments, issue of shares and bonds and specific sources of financing ( factoring financing, forfeiting financing, leasing and financing by franchise. In this paper, the accent will be put on the leasing as a specific form for financing the business entities in R. Macedonia. A research for that how much the business entities are acquainted with the advantages of using this financing source, how much the leasing is present as a financing form and if there are limiting factors in its use, will be conducted. At the end, on the basis of the obtained results from the research, some measures and recommendations for higher leasing implementation in the business entities in Republic of Macedonia will be given

Poly (vinyl chloride) / epoxidized natural rubber blends were prepared with a Brabender plasticorder at 140, 150, 160, 170 and 180 degree C mixing temperatures. They were mixed at 50 rpm rotor speed for 10 min. The blends were irradiated with doses ranging from 0-200 kGy. Changes in tensile strength, modulus at 100% elongation, gel fraction and damping properties (tan δ) of the blends with increasing mixing temperatures and irradiation doses were investigated. In general, it was observed that the mixing temperature is important in maximizing the positive effect of irradiation. Results revealed that a readily miscible blend enjoy maximum benefit from irradiation meanwhile irradiation impart miscibility to a partially miscible PVC/ENR blend. The enhancement in blend properties is believed to be attributed by the irradiation-induced crosslinking along with irradiation-induced interaction between the polymers. The radiation-induced degradation found to be prominent at higher doses for blend that has undergone excessive thermal degradation. However evidence did not reveal the specific nature of radiation-induced reaction responsible for the improved interactions of the blends. (author)

Nuclear waste disposal: achieving adequate financing - special study

International Nuclear Information System (INIS)

Quasebarth, M.V.

1984-01-01

An analysis by the Congressional Budget Office (CBO) evaluates whether the current one mill fee now charged to nuclear-electricity consumers will adequately finance the waste disposal program. The CBO found that, if the fee is adjusted annually for inflation, it should provide enough revenues to cover all program costs under all nuclear growth forecasts. If the fee is unchanged, however, the fees will be inadequate if inflation exceeds 3% annually. The report suggests two alternatives for fee revision, but makes no recommendations. The alternatives are to increase the fee only at specific intervals or to automatically adjust the fee through indexation. The report examines the effect of delaying the program, cost overruns, and alternative inflation rate and interest rate assumptions. 3 figures, 12 tables

Emerging trends in health care finance.

Access to capital will become more difficult. Capital access is dependent on ability to repay debt, which, in turn, is dependent on internally generated cash flows. Under any health care reform proposal, revenue inflows will be slowed. The use of corporate finance techniques to limit financial risk and lower cost will be a permanent response to fundamental changes to the health care system. These changes will result in greater balance sheet management, centralized capital allocation, and alternative sources of capital.

Financing of radioactive waste disposal. Finanzierung der nuklearen Entsorgung

Energy Technology Data Exchange (ETDEWEB)

Reich, J

1989-01-01

Waste disposal is modelled as a financial calculus. In this connection the particularity is not primarily the dimension to be expected of financial requirement but above all the uncertainty of financial requirement as well as the ecological, socio-economic and especially also the temporal dimension of the Nuclear Waste Disposal project (disposal of spent fuel elements from light-water reactors with and without reprocessing, decommissioning = safe containment and disposal of nuclear power plants, permanent isolation of radioactive waste from the biosphere, intermediate storage). Based on the above mentioned factors the author analyses alternative approaches of financing or financial planning. He points out the decisive significance of the perception of risks or the evaluation of risks by involved or affected persons - i.e. the social acceptance of planned and designed waste disposal concepts - for the achievement and assessment of alternative solutions. With the help of an acceptance-specific risk measure developed on the basis of a mathematical chaos theory he illustrates, in a model, the social influence on the financing of nuclear waste disposal.

Eucalyptus-Palm Kernel Oil Blends: A Complete Elimination of Diesel in a 4-Stroke VCR Diesel Engine

Directory of Open Access Journals (Sweden)

Srinivas Kommana

2015-01-01

Full Text Available Fuels derived from biomass are mostly preferred as alternative fuels for IC engines as they are abundantly available and renewable in nature. The objective of the study is to identify the parameters that influence gross indicated fuel conversion efficiency and how they are affected by the use of biodiesel relative to petroleum diesel. Important physicochemical properties of palm kernel oil and eucalyptus blend were experimentally evaluated and found within acceptable limits of relevant standards. As most of vegetable oils are edible, growing concern for trying nonedible and waste fats as alternative to petrodiesel has emerged. In present study diesel fuel is completely replaced by biofuels, namely, methyl ester of palm kernel oil and eucalyptus oil in various blends. Different blends of palm kernel oil and eucalyptus oil are prepared on volume basis and used as operating fuel in single cylinder 4-stroke variable compression ratio diesel engine. Performance and emission characteristics of these blends are studied by varying the compression ratio. In the present experiment methyl ester extracted from palm kernel oil is considered as ignition improver and eucalyptus oil is considered as the fuel. The blends taken are PKE05 (palm kernel oil 95 + eucalyptus 05, PKE10 (palm kernel oil 90 + eucalyptus 10, and PKE15 (palm kernel 85 + eucalyptus 15. The results obtained by operating with these fuels are compared with results of pure diesel; finally the most preferable combination and the preferred compression ratio are identified.

2018-04-01

This paper describes a pragmatic approach that can be applied in assessing powder blend and unit dosage uniformity of solid dose products at Process Design, Process Performance Qualification, and Continued/Ongoing Process Verification stages of the Process Validation lifecycle. The statistically based sampling, testing, and assessment plan was developed due to the withdrawal of the FDA draft guidance for industry "Powder Blends and Finished Dosage Units-Stratified In-Process Dosage Unit Sampling and Assessment." This paper compares the proposed Grouped Area Variance Estimate (GAVE) method with an alternate approach outlining the practicality and statistical rationalization using traditional sampling and analytical methods. The approach is designed to fit solid dose processes assuring high statistical confidence in both powder blend uniformity and dosage unit uniformity during all three stages of the lifecycle complying with ASTM standards as recommended by the US FDA.

A comparative study of almond biodiesel-diesel blends for diesel engine in terms of performance and emissions.

Science.gov (United States)

Abu-Hamdeh, Nidal H; Alnefaie, Khaled A

2015-01-01

This paper investigates the opportunity of using almond oil as a renewable and alternative fuel source. Different fuel blends containing 10, 30, and 50% almond biodiesel (B10, B30, and B50) with diesel fuel (B0) were prepared and the influence of these blends on emissions and some performance parameters under various load conditions were inspected using a diesel engine. Measured engine performance parameters have generally shown a slight increase in exhaust gas temperature and in brake specific fuel consumption and a slight decrease in brake thermal efficiency. Gases investigated were carbon monoxide (CO) and oxides of nitrogen (NOx). Furthermore, the concentration of the total particulate and the unburned fuel emissions in the exhaust gas were tested. A blend of almond biodiesel with diesel fuel gradually reduced the engine CO and total particulate emissions compared to diesel fuel alone. This reduction increased with more almond biodiesel blended into the fuel. Finally, a slight increase in engine NO x using blends of almond biodiesel was measured.

Combustion and exhaust emission characteristics of a compression ignition engine using liquefied petroleum gas-Diesel blended fuel

Qi, D.H.; Bian, Y.ZH.; Ma, ZH.Y.; Zhang, CH.H.; Liu, SH.Q.

2007-01-01

Towards the effort of reducing pollutant emissions, especially smoke and nitrogen oxides, from direct injection (DI) Diesel engines, engineers have proposed various solutions, one of which is the use of a gaseous fuel as a partial supplement for liquid Diesel fuel. The use of liquefied petroleum gas (LPG) as an alternative fuel is a promising solution. The potential benefits of using LPG in Diesel engines are both economical and environmental. The high auto-ignition temperature of LPG is a serious advantage since the compression ratio of conventional Diesel engines can be maintained. The present contribution describes an experimental investigation conducted on a single cylinder DI Diesel engine, which has been properly modified to operate under LPG-Diesel blended fuel conditions, using LPG-Diesel blended fuels with various blended rates (0%, 10%, 20%, 30%, 40%). Comparative results are given for various engine speeds and loads for conventional Diesel and blended fuels, revealing the effect of blended fuel combustion on engine performance and exhaust emissions

The Gateway Paper--financing health in Pakistan and its linkage with health reforms.

Science.gov (United States)

Nishtar, Sania

2006-12-01

Pakistan currently principally uses three modes of financing health--taxation, out of pocket payments and donor contributions of which the latter is the least significant in terms of size. Less than 3.6% of the employees are covered under the social security scheme and there is a limited social protection mechanism, which collectively serves the health needs of 3.4% of the population. The main issues in health financing include low spending, lack of attention to alternate sources of financing and issues with fund mobilization and utilization. With respect to the first, health reforms proposed as part of the Gateway Paper make a strong case for promoting the reallocation of tax-based revenues and developing sustainable alternatives to low levels of public spending on health. With respect to alternative sources of health financing, the Gateway Paper lays stress on exploring policy options for private health insurance, broadening the base of Employees Social Security, creating a Federal Employees Social Security Programme, developing social health insurance within the framework of a broad-based social protection strategy, which scopes beyond the formally employed sector, establishing a widely inclusive safety net for the poor; mainstreaming philanthropic grants as a major source of health financing; developing a conducive tax configuration; generating greater corporate support for social sector causes within the framework of the concept of Corporate Social Responsibility and developing cost-sharing programmes, albeit with safeguards. The Gateway Paper regards efficient fund utilization a priority and lays stress on striking a balance between minimizing costs, controlling costs and using resources more efficiently and equitably--in other words, getting the best value for the money, on the one hand, and increasing the pool of available resources, on the other. Specific interventions such as the promotion of transparent financial administration, budgeting and cost

A cycle simulation model for predicting the performance of a diesel engine fuelled by diesel and biodiesel blends

International Nuclear Information System (INIS)

Gogoi, T.K.; Baruah, D.C.

2010-01-01

Among the alternative fuels, biodiesel and its blends are considered suitable and the most promising fuel for diesel engine. The properties of biodiesel are found similar to that of diesel. Many researchers have experimentally evaluated the performance characteristics of conventional diesel engines fuelled by biodiesel and its blends. However, experiments require enormous effort, money and time. Hence, a cycle simulation model incorporating a thermodynamic based single zone combustion model is developed to predict the performance of diesel engine. The effect of engine speed and compression ratio on brake power and brake thermal efficiency is analysed through the model. The fuel considered for the analysis are diesel, 20%, 40%, 60% blending of diesel and biodiesel derived from Karanja oil (Pongamia Glabra). The model predicts similar performance with diesel, 20% and 40% blending. However, with 60% blending, it reveals better performance in terms of brake power and brake thermal efficiency.

This paper introduces the engineer who is undertaking distributed generation projects to a wide range of financing options. Distributed generation systems (such as internal combustion engines, small gas turbines, fuel cells and photovoltaics) all require an initial investment, which is recovered over time through revenues or savings. An understanding of the cost of capital and financing structures helps the engineer develop realistic expectations and not be offended by the common requirements of financing organizations. This paper discusses several mechanisms for financing distributed generation projects: appropriations; debt (commercial bank loan); mortgage; home equity loan; limited partnership; vendor financing; general obligation bond; revenue bond; lease; Energy Savings Performance Contract; utility programs; chauffage (end-use purchase); and grants.

Financing alternative energy projects: An examination of challenges and opportunities for local government

International Nuclear Information System (INIS)

Cheung, Grace; Davies, Peter J.; Trück, Stefan

2016-01-01

Local government in Australia has a strong collective capacity to reduce GHG emissions through policies, funding allocation to renewable energy projects and the delivery of programs and services. This study examines the institutional capacity of councils in Sydney and how this impacts on decisions to invest in alternative energy projects. We find greenhouse gas emission targets of councils are strongly aligned to national targets but do not reflect the local council's institutional capacity, political leadership or strategic priorities. Energy reduction projects are often identified and undertaken by environmental staff without support from financial staff or financial-evaluation tools. An absence of national guidelines to provide consistency in tracking and reporting limits cross-sector benchmarking. Street lighting contributes to a significant proportion of council's total electricity expenditure and GHG emission profile. Being highly regulated, existing contracts and the current practice of street lighting services limits the councils’ ability to reduce emissions. Based on our analysis we recommend a number of measures to overcome these constraints including the use of financial evaluation tools for small-scale renewable energy projects, a standardised national tracking and reporting platform to facilitate progress-reporting and meaningful comparative analysis between councils and policy reform to the regulation of street lighting. - Highlights: • Australian local government sector can influence up to 50% of GHG emissions. • Institutional capacity, finance, leadership and staff, influence GHG performance. • Monitoring GHG emissions is limited by a lack of national guidelines or protocols. • Environmental officers lack tools and support to assess GHG reduction projects. • Reducing GHG emissions from street lighting is a contested legal and policy area.

2015-01-01

Full Text Available A series of excellent poly(vinyl alcohol (PVA/polymers blend hydrogel were reviewed using different crosslinking types to obtain proper polymeric dressing materials, which have satisfied biocompatibility and sufficient mechanical properties. The importance of biodegradable–biocompatible synthetic polymers such as PVA, natural polymers such as alginate, starch, and chitosan or their derivatives has grown significantly over the last two decades due to their renewable and desirable biological properties. The properties of these polymers for pharmaceutical and biomedical application needs have attracted much attention. Thus, a considered proportion of the population need those polymeric medical applications for drug delivery, wound dressing, artificial cartilage materials, and other medical purposes, where the pressure on alternative polymeric devices in all countries became substantial. The review explores different polymers which have been blended previously in the literature with PVA as wound dressing blended with other polymeric materials, showing the feasibility, property change, and purpose which are behind the blending process with PVA.

Financing the UK power sector: Is the money available?

International Nuclear Information System (INIS)

Blyth, William; McCarthy, Rory; Gross, Robert

2015-01-01

The UK power generation sector faces a major new round of investment: the coincidence of asset retiring and ambitious goals for decarbonisation is not unique, but is particularly acute in the UK. The UK government has put in place a raft of new policies that seek to promote new, low carbon investment and ensure security of supply. The traditional channel for financing the sector has been through large utility companies, but this now looks challenging for various reasons. The UK therefore offers an interesting case study on several counts; the scale of the challenge, effectiveness of new policies, and the availability of alternative finance. We find that the link between the finance sector and the electricity sector is not ‘broken’, but the flow of money to the sector is threatened by the current weakness of the utilities’ business model. This paper compares estimates of the scale of investment required in the UK with historical investment rates. It summarises contemporary finance industry views of conditions and trends, and potential policy interventions that might be needed to bridge the investment gap. The potential for channelling institutional investor funds directly into energy assets is reviewed. - Highlights: • Power investment need to scale up compared to historical trends, but is achievable. • Traditionally, low-cost finance has been through bonds and shares of large utilities. • Utilities are suffering high debt, reduced demand, and suppressed prices. • Policy interventions to scale-up investment are reviewed.

Environmentally friendly materials, made from industrial waste, are being increasingly used as a solution to the growing amount of waste generated by society, but also as a cheaper alternative to replace conventional materials for use in construction. In this work were investigated the properties of polymer blends based on recycled PET and a polyester derived from terephthalic acid and glycerin, a co-product of biodiesel. The samples were characterized by XRD, TGA, DSC, FTIR and SEM. The polyester synthesized showed a degradation event near 300 deg C. The blends with higher ratio of PET showed thermal behavior similar to pure PET. The X-ray diffraction showed that the polymer blends are semicrystalline materials. The micrographs presents the presence of a smooth surface, indicating the possibility of miscibility between the arrays. Therefore, the blending makes possible the fabrication of low-cost materials with applications in several areas. (author)

Full Text Available Diesel engine is known as the most efficient engine with high efficiency and power but always reported as high fuel emission. Malaysia National Automotive Policy (NAP was targeting to improve competitive regional focusing on green technology development in reducing the emission of the engine. Therefore, ethanol was introduced to reduce the emission of the engine and while increasing its performance, Palm methyl ester was introduced as blend enhancer to improve engine performance and improve diesel-ethanol blends stability. This paper aimed to study the characteristics of the blends and to prove the ability of palm-methyl-ester as co-solvent in ethanol-diesel blends. Stability and thermophysical test were carried out for different fuel compositions. The stability of diesel-ethanol blended was proved to be improved with the addition of PME at the longer period and the stability of the blends changed depending on temperature and ethanol content. Density and viscosity of diesel-ethanol-PME blends also give higher result than diesel-ethanol blends and it's proved that PME is able to increase density and viscosity of blends. Besides, heating value of the blends also increases with the increasing PME in diesel-ethanol blends.

Although recent studies report on the benefits of blended learning in improving medical student education, there is still no empirical evidence on the relative effectiveness of blended over traditional learning approaches in medical statistics. We implemented blended along with on-site (i.e. face-to-face) learning to further assess the potential value of web-based learning in medical statistics. This was a prospective study conducted with third year medical undergraduate students attending the Faculty of Medicine, University of Belgrade, who passed (440 of 545) the final exam of the obligatory introductory statistics course during 2013-14. Student statistics achievements were stratified based on the two methods of education delivery: blended learning and on-site learning. Blended learning included a combination of face-to-face and distance learning methodologies integrated into a single course. Mean exam scores for the blended learning student group were higher than for the on-site student group for both final statistics score (89.36±6.60 vs. 86.06±8.48; p = 0.001) and knowledge test score (7.88±1.30 vs. 7.51±1.36; p = 0.023) with a medium effect size. There were no differences in sex or study duration between the groups. Current grade point average (GPA) was higher in the blended group. In a multivariable regression model, current GPA and knowledge test scores were associated with the final statistics score after adjusting for study duration and learning modality (pstatistics to undergraduate medical students. Blended and on-site training formats led to similar knowledge acquisition; however, students with higher GPA preferred the technology assisted learning format. Implementation of blended learning approaches can be considered an attractive, cost-effective, and efficient alternative to traditional classroom training in medical statistics.

Environment issue is a principle driving force which has led to a considerable effort to develop and introduce alternative fuels for transportation. India has large potential for production of biofuels like biodiesel from vegetable seeds. Use of biodiesel namely, tamanu methyl ester (TME) in unmodified diesel engines leads to low thermal Efficiency and high smoke emission. To encounter this problem hydrogen was inducted by a port fueled injection system. Hydrogen is considered to be low polluting fuel and is the most promising among alternative fuel. Its clean burning characteristic and better performance attract more interest compared to other fuels. It was more active in reducing smoke emission in biodiesel. A main drawback with hydrogen fuel is the increased NO x emission. To reduce NO x emission, TME-ethanol blends were used in various proportions. After a keen study, it was observed that ethanol can be blended with biodiesel up to 30% in unmodified diesel engine. The present work deals with the experimental study of performance and emission characteristic of the DI diesel engine using hydrogen and TME-ethanol blends. Hydrogen and TME-ethanol blend was used to improve the brake thermal efficiency and reduction in CO, NO x and smoke emissions. Copyright © 2015 Elsevier Inc. All rights reserved.

Considering energy crises and pollution problems today, investigations have been concentrated on decreasing fuel consumption by using alternative fuels and on lowering the concentration of toxic components in combustion products. In the present work a quasi-dimensional model was developed to study the effect of hydrogen blending on fuel consumption and pollutant concentrations. The results of the study show that the maximum improvement in engine thermal efficiency occurs at 8% hydrogen blending. The results also show that 10% hydrogen blending reduces CO concentration by 73.8% but the NO concentration increases by 100%. However the problem of increasing NO concentration was solved by operating the engine with lean mixture. Hydrogen blending also reduces the specific fuel consumption until about 6% blending, then the effect becomes marginal. (Author)

Dynamics, Miscibility, and Morphology in Polymer-Molecule Blends: The Impact of Chemical Functionality

2015-10-22

In the quest to improve the performance of organic bulk-heterojunction solar cells, many recent efforts have focused on developing molecular and polymer alternatives to commonly used fullerene acceptors. Here, molecular dynamics simulations are used to investigate polymer-molecule blends comprised of the polymer donor poly(3-hexylthiophene) (P3HT) with a series of acceptors based on trialkylsilylethynyl-substituted pentacene. A matrix of nine pentacene derivatives, consisting of systematic chemical variation both in the nature of the alkyl groups and electron-withdrawing moieties appended to the acene, is used to draw connections between the chemical structure of the acene acceptor and the nanoscale properties of the polymer-molecule blend. These connections include polymer and molecular diffusivity, donor-acceptor packing and interfacial (contact) area, and miscibility. The results point to the very significant role that seemingly modest changes in chemical structure play during the formation of polymer-molecule blend morphologies.

Using commodity-indexed financing to fund OPEC/Alaska's development projects

International Nuclear Information System (INIS)

Essayyad, Musa

1992-01-01

An impediment to the process of economic diversification in OPEC and Alaska is the lack of favourable access to local and international capital markets to finance development projects, particularly mineral resource development. This paper highlights the importance of commodity-indexed bonds, including oil- and gold- indexed bonds, as a financing alternative to supplement the supply shortage of loanable funds from conventional, local and international commercial banks. The indexation concept is discussed, features of different bonds issued to date are contrasted and the benefits and risks for borrowers and investors are highlighted. An analysis is made of the experience of OPEC and Alaska in using commodity-indexed bonds and the feasibility of Alaska and some OPEC countries entering into commodity-linked-financed joint ventures is examined. Future prospects for commodity-linked bonds are explored. Not withstanding the fact that the immediate market timing is unfavourable, the long-term benefits of commodity-indexed securities are recognized. (U.K.)

1997-01-01

The effect of irradiation on the physical properties of Polyvinyl Chloride / Epoxidised Natural Rubber Blends (PVC/ENR blends) were investigated. The enhancement in tensile strength, elongation at break, hardness and aging properties of the blends have confirmed the positive effect of irradiation on the blends. It is evident from gel fraction and infra red spectroscopic studies that the blends of PVC and ENR cross-linked upon irradiation. The results also revealed that at any blend composition, the enhancement in properties depend on irradiation dose which controls the degree of radiation induced cross-linking. In an attempt to maximize the constructive effect of irradiation, the influence of various additives such as stabilizers, radiation sensitizers, fillers and processing aids on the blend properties were studied. The changes in blend properties upon irradiation with the presents of above additives were also presented in this paper

This paper provides an overview of the recent trend towards private ownership and financing of power projects in the developing countries, focusing on the role played by both private and public agencies in meeting the large financing challenges. The paper draws upon the operational experience of the International Finance Corporation, which has been involved in the financing of more than 30 private power projects in the developing countries over the past three decades. Among the issues that affect implementation of private power projects is the balancing of risk and reward to equity investors and to commercial lenders. The paper discusses the principal sources of risk and the strategies used to manage them. A related issue is the competition for capital on the international markets, and the techniques that are being devised to bring more finance to the power sector. Finally, the paper considers the role of government in bringing private investors to the power sector, and the approaches being adopted to balance the needs of investors with the needs of the public.

An increased interest for hygiene in everyday life as well as in food, feed and medical issues lead to a strong interest in films and blends to prevent the growth and accumulation of harmful bacteria. A growing trend is to use synthetic and natural antimicrobial polymers, to provide non-migratory and non-depleting protection agents for application in films, coatings and packaging. In food packaging, antimicrobial effects add up to the barrier properties of the materials, to increase the shelf life and product quality. Chitosan is a natural bioactive polysaccharide with intrinsic antimicrobial activity and, due to its exceptional physicochemical properties imparted by the polysaccharide backbone, has been recognized as a natural alternative to chemically synthesized antimicrobial polymers. This, associated with the increasing preference for biofunctional materials from renewable resources, resulted in a significant interest on the potential for application of chitosan in packaging materials. In this review we describe the latest developments of chitosan films and blends as packaging material. Copyright © 2014 Elsevier Ltd. All rights reserved.

Successful coal blending requires finding a careful balance between fuel costs and plant performance. A recent study of a Malaysian power plant shows how the utility (Tenaga Nasional Berhad (TNB)) could reduce fuel costs while avoiding boiler operating problems normally associated with firing low-grade coals. TNB`s Kaper 2220 MW power station in Selangor needed an improved method of coal blending for two new 500 MW units and for two existing 300 MW units. UK`s Power Technology was commissioned to identify what coal blends the boiler could tolerate. A Coal Quality Impact Model (CQIM) analysis of the effect of different coals and coal blends on combustion performance and economics, and a performance analysis of coal yard handling facility was made to determine whether the accuracy of the required blend could be achieved (using a Coal Handling Simulation, CHAS, software package). The CQIM study showed that the proportion of cheaper coals could be increased from 20% to 50% provided each shipment was adequately sampled. The CHAS study showed that use of a flat back reclaimer or modifications to the dry coal stove would allow accurate blending. 5 figs., 1 tab.

Full Text Available Fossil fuel resources are being depleted day by day and its use affects the environment adversely. Renewable energy is one of the alternate for sustainable development and biodiesel is one of the suitable alternate which can replace the diesel. The major hurdles in the successful commercialization of biodiesel are high feedstock cost and conversion technology to reduce viscosity. The choice of raw material and biodiesel production method must depend upon techno-economical view. There are some specific regions for different types of oil availability. It is therefore required to produce biodiesel from the mixture of oils to fulfill the requirements of energy demand in a particular country according to its suitability and availability of feedstock. Karanja and Linseed crops  are abundantly available in India. Biodiesel was produced from a mixture of Karanja and Linseed oils by alkaline transesterification. In this experimental study, biodiesel blends of 10%, 20% and 30% were used with diesel in a diesel engine at a constant speed of 1500 rpm with varying brake powers (loads from 0.5 kW to 3.5kW to evaluate brake thermal efficiency, brake specific fuel consumption,  brake specific energy consumption, exhaust gas temperature, mechanical efficiency, volumetric efficiency, air fuel ratio and smoke opacity. They were compared with diesel and found satisfactory. BTE was found to be  28.76% for B10 at 3.5kW load.  Smoke opacity was also found to be reduced with all blends. Smoke opacity was found to be reduced up to 10.23% for B10 biodiesel blend as compared to that of diesel at 3.5kW. Experimental investigation  has revealed that  biodiesel produced from a mixture of Karanja and Linseed oils can be successfully used in diesel engines without any engine modification  and B10 was found to be an optimum biodiesel blend in terms of brake thermal efficiency. Article History: Received April 14th 2016; Received in revised form June 25th 2016; Accepted

Raouf Mahmood Raouf

2016-04-01

Full Text Available The use of transparent polymers as an alternative to glass has become widespread. However, the direct exposure of these materials to climatic conditions of sunlight and heat decrease the lifetime cost of these products. The aim of this study was to minimize the harm caused by ultraviolet (UV radiation exposure to transparent poly(methylmethacrylate (PMMA, which usually leads to changes in the physical and chemical properties of these materials and reduced performance. This was achieved using environmentally friendly cellulose acetate butyrate (CAB. The optical, morphological, and thermal properties of CAB blended with transparent PMMA was studied using UV-VIS spectrophotometry, scanning electron microscopy, X-ray diffraction, dynamic mechanical analysis, and thermal gravimetric analysis. The results show that CAB was able to reduce the effects of UV radiation by making PMMA more transparent to UV light, thereby preventing the negative effects of trapped radiation within the compositional structure, while maintaining the amorphous structure of the blend. The results also show that CAB blended with PMMA led to some properties commensurate with the requirements of research in terms of a slight increase in the value of the modulus and the glass transition temperature for the PMMA/CAB blend.

This paper investigates the diesel engine performance and exhaust emissions with marine gas oil-alternative fuel additive. Marine gas oil (MGO) was selected as base fuel for the engine experiments. An oxygenate, diethylene glycol dimethyl ether (DGM), and a biodiesel (BD) jatropha oil methyl ester (JOME) with a volume of 10% were blended with the MGO fuel. JOME was derived from inedible jatropha oil. Lower emissions with diesel-BD blends (soybean methyl ester, rapeseed methyl ester etc.) have been established so far, but the effect of MGO-BD (JOME) blends on engine performance and emissions has been a growing interest as JOME (BD) is derived from inedible oil and MGO is frequently used in maritime transports. No phase separation between MGO-DGM and MGO-JOME blends was found. The neat MGO, MGO-DGM and MGO-JOME blends are termed as MGO, Ox10 and B10 respectively. The experiments were conducted with a six-cylinder, four-stroke, turbocharged, direct-injection Scania DC 1102 (DI) diesel engine. The experimental results showed significant reductions in fine particle number and mass emissions, PM and smoke emissions with Ox10 and B10 fuels compared to the MGO fuel. Other emissions including total unburned hydrocarbon (THC), carbon monoxide (CO) and engine noise were also reduced with the Ox10 and B10 fuels, while maintaining similar brake specific fuel consumption (BSFC) and thermal efficiency with MGO fuel. Oxides of nitrogen (NOx) emissions, on the other hand, were slightly higher with the Ox10 and B10 fuels at high engine load conditions.

Intuition suggests that corporate investment should be decreasing in financing constraints. We show that even when financing is obtained using a standard debt contract and there is symmetric information between the firm and outside investors, the relation is actually U-shaped. We thus provide a new...... theoretical explanation for the recent empirical findings of Cleary et al. (2007). We split up the endogenously implied financing costs and propose a trade-off between expected liquidation costs and second-best investment costs. For rather unconstrained firms, the risk of costly liquidation dominates the cost...

Biodegradable polymers represent a solution for the environment protection: they decrease the landfill space, by declining the petrochemical sources, and offer also an alternative solution for the recycling. The behavior during degradation in the presence of active sludge of some polyvinyl chloride (PVC) based blends with variable content of hydrolyzed collagen (HC) has been followed. Some samples were subjected to UV irradiation, for 30 hours. The modifications induced in the environment by the polymer systems (pH variation, bacterial composition), as well as the changes of the properties of the blends (weight losses, aspect etc.) were studied. During the first moments of degradation in active sludge, all the samples absorbed water, behavior which favored the biodegradation. The bacteriological analysis of the sludge indicates the presence of some microbiological species. Generally, the populations of microorganisms decrease, excepting the sulphito-reducing anaerobic bacteria, the actinomycetes and other anaerobic bacteria. PVC/HC blends are degraded with a significant rate in active sewage sludge. More susceptible for the degradation are the UV irradiated blends. After the migration of the components with a small molecular mass in the environment, the natural polymer is degraded. The degradation effect increases with the content in the natural polymer.

The Energy Policy and Systems Analysis Office of DOE has requested a tool to compare the impact of various Federal policies on the financial viability of generation resources across the country. Policy options could include production tax credits, investment tax credits, solar renewable energy credits, tax abatement, accelerated depreciation, tax-free loans, and others. The tool would model the finances of projects in all fifty states, and possibly other geographic units like utility service territories and RTO/ISO territories. The tool would consider the facility s cost, financing, production, and revenues under different capital and market structures to determine things like levelized cost of energy, return on equity, and cost impacts on others (e.g., load-serving entities, society.) The tool would compare the cost and value of the facility to the local regional alternatives to determine how and where policy levers may provide sufficient incremental value to motivate investment. The results will be displayed through a purpose-built visualization that maps geographic variations and shows associated figures and tables.

From the environmental point of view, biodegradable materials have been rapidly developed in the past years. PVA is one of the biodegradable synthetic polymers commonly used, but its degradation rate is slow. As an alternative to reduce plastic waste and accelerate the degradation process, PVA frequently blended with other natural polymers to improve its biodegradability. The natural polymer such as starch has high potential in enhancing PVA biodegradability by blending both components. The usage of starch extracted from agriculture wastes such as jackfruit seed is quite promising. In this study, jackfruit seed starch (JFSS)/poly (vinyl alcohol) (PVA) blend films were prepared using the solution casting method. The effect of starch content on the mechanical (tensile strength and elongation to break %) and physical properties of the tested films were investigated. The optimum tensile strength was obtained at 10.45 MPa when 4 wt. % of starch added to the blend. But, decreasing trend of tensile strength was found upon increasing the amount of starch beyond 4 wt. % in starch/PVA blend films. Nevertheless, elongation at break decreases with the increase in starch content. The mechanical properties of the blend films are supported by the Field Emission Scanning Electron Microscopy (FESEM), in which the native JFSS granules are wetted by PVA continuous phase with good dispersion and less agglomeration. The incorporation of JFSS in PVA has also resulted in the appearance of hydrogen bond peak, which evidenced by Fourier Transform Infrared (FTIR). Additionally, the biodegradation rate of JFSS/PVA was evaluated through soil burial test.

A six step framework is followed: i identify the focal issue; ii summarize current mandatory blending targets; iii identify the driving forces as of a macro-environmental analysis; iv validate driving forces with specialists; v rank such key forces by importance before uncertainties, building a correlation matrix; vi design the scenarios. Finally, three alternative scenarios, relative to the adoption on behalf of countries, by the year 2020, of mandatory bio-fuel blending targets, are proposed which might guide these countries’ decision makers when planning production systems.

The use of Biofuels has been gaining in popularity over the past few years due to their ability to reduce the dependence on fossil fuels. Biofuels as a renewable energy source can be a viable option for sustaining long-term energy needs if they are managed efficiently. We describe our initial efforts to exploit algae, halophytes and other non-crop plants to produce synthetics for fuel blends that can potentially be used as fuels for aviation and non-aerospace applications. Our efforts have been dedicated to crafting efficient extraction and refining processes in order to extract constituents from the plant materials with the ultimate goal of determining the feasibility of producing biomass-based jet fuel from the refined extract. Two extraction methods have been developed based on communition processes, and liquid-solid extraction techniques. Refining procedures such as chlorophyll removal and transesterification of triglycerides have been performed. Gas chromatography in tandem with mass spectroscopy is currently being utilized in order to qualitatively determine the individual components of the refined extract. We also briefly discuss and compare alternative methods to extract fuel-blending agents from alternative biofuels sources.

Alternate Fuels for Use in Commercial Aircraft

2008-01-01

The engine and aircraft Research and Development (R&D) communities have been investigating alternative fueling in near-term, midterm, and far-term aircraft. A drop in jet fuel replacement, consisting of a kerosene (Jet-A) and synthetic fuel blend, will be possible for use in existing and near-term aircraft. Future midterm aircraft may use a biojet and synthetic fuel blend in ultra-efficient airplane designs. Future far-term engines and aircraft in 50-plus years may be specifically designed to use a low- or zero-carbon fuel. Synthetic jet fuels from coal, natural gas, or other hydrocarbon feedstocks are very similar in performance to conventional jet fuel, yet the additional CO2 produced during the manufacturing needs to be permanently sequestered. Biojet fuels need to be developed specifically for jet aircraft without displacing food production. Envisioned as midterm aircraft fuel, if the performance and cost liabilities can be overcome, biofuel blends with synthetic jet or Jet-A fuels have near-term potential in terms of global climatic concerns. Long-term solutions address dramatic emissions reductions through use of alternate aircraft fuels such as liquid hydrogen or liquid methane. Either of these new aircraft fuels will require an enormous change in infrastructure and thus engine and airplane design. Life-cycle environmental questions need to be addressed.

2010-07-01

Full Text Available Blended learning as a combination of classroom teaching and e-learning has become a widely represented standard in employee and management development of companies. The exploratory survey “Blended Learning@University” conducted in 2008 investigated the integration of blended learning in higher education. The results of the survey show that the majority of participating academic teachers use blended learning in single courses, but not as a program of study and thus do not exploit the core performance potential of blended learning. According to the study, the main driver of blended learning performance is its embeddedness in higher education. Integrated blended programs of study deliver the best results. In blended learning, learning infrastructure (in terms of software, culture, skills, funding, content providing, etc. does not play the role of a performance driver but serves as an enabler for blended learning.

Improvements to the Composition of Fusel Oil and Analysis of the Effects of Fusel Oil–Gasoline Blends on a Spark-Ignited (SI Engine’s Performance and Emissions

Directory of Open Access Journals (Sweden)

2018-03-01

Full Text Available With the increase of energy needs and environmental pollution, alcohol-based alternative fuels are used in spark-ignited (SI engines. Fusel oil, which is a by-product obtained through distillation of ethanol, contains some valuable alcohols. As alcohols are high-octane, they have an important place among the alternative fuels. Fusel also takes its place among those alternatives as it is high-octane and low on exhaust emissions. In this research, the effects of using blends of unleaded gasoline and improved fusel oil on engine performance and exhaust emissions were analyzed experimentally. A four-stroke, single-cylinder, spark-ignited engine was used in the experiments. The tests were conducted at a fixed speed and under different loads. The test fuels were blended supplying with fusel oil at rates incremented by 10%, up to 50%. Under each load, the engine’s performance and emissions were measured. Throughout the experiments, it has been observed that engine torque and specific fuel consumption increases as the amount of fusel oil in the blend is increased. Nitrogen oxide (NOx, carbon monoxide (CO, and hydrocarbon (HC emissions are reduced as the amount of fusel oil in the blends is increased.

International energy financing

Vedavalli, Rangaswamy

1994-01-01

Some of the innovative financing options being considered by developing countries and economies in transition as ways of mobilizing international energy financing are discussed. Build-Own-Operate (BOO) and Transfer (BOOT) is the most commonly adopted approach. This involves limited resource financing of a project on the basis of the associated cash flow and risks and not on the credit of the project owners. The World Bank has set up the Multilateral Investment Guarantee Agency to provide, on a fee basis, guarantees against certain non-commercial forms of risk in order to promote international capital flow to developing countries. In 1989, the World Bank introduced the Expanded Co-financing Operations (ECO) programme as an instrument to catalyze the flow of private finance into developing countries and to improve their access to international financial markets. Other financial instruments currently being established include: leasing of equipment or whole plants by foreign investors; private ownership or operation of generation and distribution facilities; exchange of specific export goods for energy imports; developing instruments to finance local costs; revenue bonds; tax-exempt bonds; sale of electricity futures to those seeking more stable, longer term electricity price contracts.

Full Text Available For small enterprises, unlike large ones, the issue of fundraising emerges both in the process of their creation, development and current activity. Small enterprises are experiencing quite a high demand for additional sources of financing. The aim of the research is to study innovative forms of financing the creation and development of small enterprises, their advantages and disadvantages. At present in addition to traditional ways of raising capital, such as bank loans or public offering of shares among external investors (IPOs, there exist a number of alternative options. Among them the most common are grants, international programs, loans from international banks and financial institutions, such as EBRD (European Bank for Reconstruction and Development, IFC (International Finance Corporation, NEFCO (Nordic Environment Finance Corporation, KfW (Kreditanstalt f?r Wiederaufbau, fundraising, crowdsourcing, crowdfunding, and angel investment. The article studies in detail the last two ways of financing: their essence, components, positive and negative features, experience of application in Ukraine and the world. The research shows that crowdfunding is suitable for business development at the early stages, that is, for those enterprises that require, for example, to complete prototyping and start mass production of their first product. Business angels can be a good choice for enterprises that already have a permanent customer base and want to grow their business.

Biodiesels have received increasing attention as alternative fuels for diesel engines and generators. This study investigates the emissions of particulate matter (PM), total carbon (TC), e.g., organic/elemental carbons, and polycyclic aromatic hydrocarbons (PAHs) from a diesel generator fuelled with soy-biodiesel blends. Among the tested diesel blends (B0, B10 (10 vol% soy-biodiesel), B20, and B50), B20 exhibited the lowest PM emission concentration despite the loads (except the 5 kW case), whereas B10 displayed lower PM emission factors when operating at 0 and 10 kW than the other fuel blends. The emission concentrations or factors of EC, OC, and TC were the lowest when B10 or B20 was used regardless of the loading. Under all tested loads, the average concentrations of total-PAHs emitted from the generator using the B10 and B20 were lower (by 38% and 28%, respectively) than those using pure petroleum diesel fuel (B0), while the emission factors of total-PAHs decreased with an increasing ratio of biodiesel to premium diesel. With an increasing loading, although the brake specific fuel consumption decreased, the energy efficiency increased despite the bio/petroleum diesel ratio. Therefore, soy-biodiesel is promising for use as an alternative fuel for diesel generators to increase energy efficiency and reduce the PM, carbon, and PAH emissions.

2012-12-01

Full Text Available Medical writing activities which may have a context and seem to be engaging may be perceived as demotivating by the students of medicine. This opinion was confirmed by the learners' responses to the open-ended question given to them prior to this study. In their responses students evaluated the writing section of English course negatively. The negative views about the writing course posed a problem to the class teacher. The computer technology and the Internet can easily be integrated into language classroom if activities are designed carefully, and carried out systematically. These attempts brought about a new understanding to teaching and learning: blended learning (BL. The purpose of this research was to investigate students of medicine attitude to blended writing classes. It was conducted with second year learners in the Faculty of Medicine at Kashan University of Medical Sciences. The first reflection aimed at finding out medical students' attitude toward blended writing lessons. Although learners' attitude to writing lessons was negative in the first reflections, they changed into positive in the latter ones. The findings indicated that blended writing class had changed students' perception of writing lessons positively. Therefore, this kind of classes may help students develop a positive attitude towards writing by providing meaningful writing opportunities. Like the student portfolio before it, the weblog faces challenges with practicality and security, but ultimately provides an alternative way to teach and assess authentic writing and reading skills. Blog Assisted Language Learning not only provides teachers with an exciting new way to approach communicative language learning, it also gives the students a new reason to enjoy writing! The paper concludes that Internet tools have the potential to be a transformational technology for teaching and learning writing, and teachers ought to give strong consideration to the setting up their

Full Text Available Although recent studies report on the benefits of blended learning in improving medical student education, there is still no empirical evidence on the relative effectiveness of blended over traditional learning approaches in medical statistics. We implemented blended along with on-site (i.e. face-to-face learning to further assess the potential value of web-based learning in medical statistics.This was a prospective study conducted with third year medical undergraduate students attending the Faculty of Medicine, University of Belgrade, who passed (440 of 545 the final exam of the obligatory introductory statistics course during 2013-14. Student statistics achievements were stratified based on the two methods of education delivery: blended learning and on-site learning. Blended learning included a combination of face-to-face and distance learning methodologies integrated into a single course.Mean exam scores for the blended learning student group were higher than for the on-site student group for both final statistics score (89.36±6.60 vs. 86.06±8.48; p = 0.001 and knowledge test score (7.88±1.30 vs. 7.51±1.36; p = 0.023 with a medium effect size. There were no differences in sex or study duration between the groups. Current grade point average (GPA was higher in the blended group. In a multivariable regression model, current GPA and knowledge test scores were associated with the final statistics score after adjusting for study duration and learning modality (p<0.001.This study provides empirical evidence to support educator decisions to implement different learning environments for teaching medical statistics to undergraduate medical students. Blended and on-site training formats led to similar knowledge acquisition; however, students with higher GPA preferred the technology assisted learning format. Implementation of blended learning approaches can be considered an attractive, cost-effective, and efficient alternative to traditional

Full Text Available The study of behavioral finance combines the investigation and expertise from research and practice into smart portfolios of individual investors’ portfolios. Understanding cognitive errors and misleading emotions drive investors to their long-term goals of financial prosperity and capital preservation. 10 years ago, Behavioral Finance was still considered an incipient, adolescent science. First Nobel Prize in Economics awarded to the study of Behavioral Economics in 2002 established the field as a new, respected study of economics. 2013 Nobel Prize was awarded to three economists, one of them considered the one of the founders of the Behavioral Finance. As such, by now we are entering the coming of age of behavioral finance. It is now recognized as a science of understanding investors behaviors and their biased patterns. It applies quantitative finance and provides practical models grounded on robust understanding of investors behavior toward financial risk. Financial Personality influences investment decisions. Behavioral portfolio construction methods combine classic finance with rigorously quantified psychological metrics and improves models for financial advice to enhance investors chances in reaching their lifetime financial goals. Behavioral finance helps understanding psychological profile dissimilarities of individuals and how these differences manifest in investment decision process. This new science has become now a must topic in modern finance.

Highlights: • Combustion characteristics of acetone–butanol–ethanol (ABE) and diesel blends. • Feasibility of ABE to be blended directly with diesel in engine. • Conventional and low temperature combustion in constant volume chamber. • ABE–diesel blends can suppress the soot formation and achieve better combustion. - Abstract: The combustion characteristics of acetone–butanol–ethanol (ABE) and diesel blends were studied in a constant volume chamber under both conventional diesel combustion and low temperature combustion (LTC) conditions. In this work, 20 vol.% ABE without water (ABE20) was mixed with diesel and the vol.% of acetone, butanol and ethanol were kept at 30%, 60% and 10% respectively. The advantageous combustion characteristics of ABE-diesel include higher oxygen content which promotes soot oxidation compared to pure diesel; longer ignition delay and soot lift-off length allowing more air entrainment upstream of the spray jet thus providing better air–fuel mixing. Based on the analysis, it is found that at low ambient temperature of 800 K and ambient oxygen of 11%, ABE20 presented close-to-zero soot luminosity with better combustion efficiency compared to D100 suggesting that ABE, an intermediate product during ABE fermentation, is a very promising alternative fuel to be directly used in diesel engines especially under LTC conditions. Meanwhile, ABE–diesel blends contain multiple components possessing drastically different volatilities, which greatly favor the occurrence of micro-explosion. This feature may result in better atomization and air–fuel mixing enhancement, which all contribute to the better combustion performance of ABE20 at LTC conditions

To reduce greenhouse gas emissions, which contribute to global warming, production of gasoline blended with ethyl tert-buthyl ether (ETBE) is increasing annually. The flash point of ETBE is higher than that of gasoline, and blending ETBE into gasoline will change the flash point and the vapor pressure. Therefore, it is expected that the fire hazard caused by ETBE-blended gasoline would differ from that caused by normal gasoline. The aim of this study was to acquire the knowledge required for estimating the fire hazard of ETBE-blended gasoline. Supposing that ETBE-blended gasoline was a two-component mixture of gasoline and ETBE, we developed a prediction model that describes the vapor pressure and flash point of ETBE-blended gasoline in an arbitrary ETBE blending ratio. We chose 8-component hydrocarbon mixture as a model gasoline, and defined the relation between molar mass of gasoline and mass loss fraction. We measured the changes in the vapor pressure and flash point of gasoline by blending ETBE and evaporation, and compared the predicted values with the measured values in order to verify the prediction model. The calculated values of vapor pressures and flash points corresponded well to the measured values. Thus, we confirmed that the change in the evaporation characteristics of ETBE-blended gasoline by evaporation could be predicted by the proposed model. Furthermore, the vapor pressure constants of ETBE-blended gasoline were obtained by the model, and then the distillation curves were developed. Copyright © 2015 Elsevier B.V. All rights reserved.

Modifications for use of methanol or methanol-gasoline blends in automotive vehicles, September 1976-January 1980

Energy Technology Data Exchange (ETDEWEB)

Patterson, D.J.; Bolt, J.A.; Cole, D.E.

1980-01-01

Methanol or blends of methanol and gasoline as automotive fuels may be attractive means for extending the nation's petroleum reserves. The present study was aimed at identifying potential problems and solutions for this use of methanol. Retrofitting of existing vehicles as well as future vehicle design have been considered. The use of ethanol or higher alcohols was not addressed in this study but will be included at a later date. Several potentially serious problems have been identified with methanol use. The most attractive solutions depend upon an integrated combination of vehicle modifications and fuel design. No vehicle problems were found which could not be solved with relatively minor developments of existing technology providing the methanol or blend fuel was itself engineered to ameliorate the solution. Research needs have been identified in the areas of lubrication and materials. These, while apparently solvable, must precede use of methanol or methanol-gasoline blends as motor fuels. Because of the substantial costs and complexities of a retrofitting program, use of methanol must be evaluated in relation to other petroleum-saving alternatives. Future vehicles can be designed initially to operate satisfactorily on these alternate fuels. However a specific fuel composition must be specified around which the future engines and vehicles can be designed.

Nursing students often feel unprepared to communicate effectively with patients and other healthcare workers within the clinical environment. Blended learning pedagogy-based communication skills training can provide an alternative to traditional methods of teaching to enhance students' satisfaction and self-efficacy levels in communicating with others. To examine the effectiveness of blended learning pedagogy in a redesigned communication module among nursing undergraduates in enhancing their satisfaction levels and attitudes towards learning communication module as well as self-efficacy in communication. A single group pre-test and post-test quasi-experimental design was adopted. Data were collected from August 2016 to November 2016 from 124 nursing undergraduates from a leading nursing school. Blended learning pedagogy was adopted to redesign a communication module that offered a wide array of learning opportunities via face-to-face classroom and online sessions. Validated and reliable instruments were used to measure satisfaction levels with blended learning pedagogy, attitudes towards learning communication, and communication self-efficacy. Descriptive and inferential statistics were used to analyze the data. Participants had enhanced satisfaction levels with blended learning pedagogy, better attitudes in learning communication skills, and improved communication self-efficacies at posttest (week 13 of the semester) when compared with their pre-test scores (week one of the semester). Participants scored higher in the Blended Learning Satisfaction Scale, the Communication Skills Attitude Scale, and the communication skills subscale of the Nursing Students Self-Efficacy Scale. Blended learning pedagogy can be effectively used in facilitating communication modules and enhancing student outcomes among nursing undergraduates. The long-term effectiveness of using blended learning pedagogy in

From Finance Capitalism to Financialization

Hansen, Per H.

In this article I interpret 150 years of financial history with a focus on shifts in the role of finance in society. I argue that over time the role of finance has shifted twice from that of servant to that of master of society, and that this process has been driven by sense making through...... narratives that legitimized and shaped these changes. When finance became a master rent seeking, cultural capture and out-of control financial innovation resulted in financial and social instability. Finance as a master was the characteristic of finance capitalism from around 1900......–1931 and of financialization from around 1980 to today. Finance capitalism and financialization were enabled by a dominant narrative that legitimized the power of finance. The shifts in the role of finance happened when crises undermined the meaning of the existing narrative and created for a new narrative able to make sense...

James, Jessica

2017-01-01

Quantitative finance is a field that has risen to prominence over the last few decades. It encompasses the complex models and calculations that value financial contracts, particularly those which reference events in the future, and apply probabilities to these events. While adding greatly to the flexibility of the market available to corporations and investors, it has also been blamed for worsening the impact of financial crises. But what exactly does quantitative finance encompass, and where did these ideas and models originate? We show that the mathematics behind finance and behind games of chance have tracked each other closely over the centuries and that many well-known physicists and mathematicians have contributed to the field.

Watanabe, Hiroshi

2010-03-01

The entanglement length Le of polymer chains (corresponding to the entanglement molecular weight Me) is not an intrinsic material parameter but changes with the interaction with surrounding chains. For miscible blends of cis-polyisoprene (PI) and poly(tert-butyl styrene) (PtBS), changes of Le on blending was examined. It turned out that the Le averaged over the number fractions of the Kuhn segments of the components (PI and PtBS) satisfactorily describes the viscoelastic behavior of pseudo-monodisperse blends in which the terminal relaxation time is the same for PI and PtBS.

Study of the Effects of Ethanol As an Additive with a Blend of Poultry Litter Biodiesel and Alumina Nanoparticles on a Diesel Engine

Directory of Open Access Journals (Sweden)

Ramesha D. K.

2017-12-01

Full Text Available With the increasing population and rise in industrialization, the demand for petroleum reserves is increasing almost daily. This is causing depletion of the non-renewable energy resources. This work aims to find an alternative fuel for diesel engines. The use of poultry litter oil biodiesel obtained from poultry industry waste, which is a non-edible source for biodiesel, is very encouraging as an alternative fuel for diesel engines. The aim of this study is to observe and maximize the performance of poultry litter oil biodiesel by adding alumina nanoparticles and ethanol. The biodiesel is prepared with acid and the base catalysed transesterification of poultry litter oil with methanol using concentrated sulphuric acid and potassium hydroxide as catalysts. The experimentation is carried out on a CI engine with three different blends - B20 biodiesel blend, B20 biodiesel blend with 30 mg/L alumina nanoparticles, and B20 biodiesel blend with 30 mg/L alumina nanoparticles and 15 ml/L ethanol. The performance, combustion and emission characteristics of all three blends are compared with neat diesel. The results of the experiment show that ethanol as an additive improves the combustion and performance characteristics. It increases the brake thermal efficiency and peak cylinder pressure. It also reduces CO and UBHC emissions and there is a marginal increase in NOx emissions as compared to neat diesel.

Deason, Jeff [Lawrence Berkeley National Lab. (LBNL), Berkeley, CA (United States). Electricity Markets and Policy Group

2017-07-31

Berkeley Lab examines criteria for a comparative assessment of multiple financing programs for energy efficiency, developed through a statewide public process in California. The state legislature directed the California Alternative Energy and Advanced Transportation Financing Authority (CAEATFA) to develop these criteria. CAEATFA's report to the legislature, an invaluable reference for other jurisdictions considering these topics, discusses the proposed criteria and the rationales behind them in detail. Berkeley Lab's brief focuses on several salient issues that emerged during the criteria development and discussion process. Many of these issues are likely to arise in other states that plan to evaluate the impacts of energy efficiency financing programs, whether for a single program or multiple programs. Issues discussed in the brief include: -The stakeholder process to develop the proposed assessment criteria -Attribution of outcomes - such as energy savings - to financing programs vs. other drivers -Choosing the outcome metric of primary interest: program take-up levels vs. savings -The use of net benefits vs. benefit-cost ratios for cost-effectiveness evaluation -Non-energy factors -Consumer protection factors -Market transformation impacts -Accommodating varying program goals in a multi-program evaluation -Accounting for costs and risks borne by various parties, including taxpayers and utility customers, in cost-effectiveness analysis -How to account for potential synergies among programs in a multi-program evaluation

Schmidt, Anatoly

2006-03-01

There has been growing interest among physicists to Econophysics, i.e. analysis and modeling of financial and economic processes using the concepts of theoretical Physics. There has been also perception that the financial industry is a viable alternative for those physicists who are not able or are not willing to pursue career in their major field. However in our times, the Wall Street expects from applicants for quantitative positions not only the knowledge of the stochastic calculus and the methods of time series analysis but also of such concepts as option pricing, portfolio management, and risk measurement. Here I describe a synthetic course based on my book ``Quantitative Finance for Physicists'' (Elsevier, 2004) that outlines both worlds: Econophysics and Mathematical Finance. This course may be offered as elective for senior undergraduate or graduate Physics majors.

Blends containing 75 wt. % of an amorphous polylactide (PLA) with two different molecular weights and 25 wt. % of a poly[(butylene adipate)-co-terephthalate] (PBAT) were prepared using either a Brabender batch mixer or a twin-screw extruder. These compounds were selected because blending PLA with PBAT can overcome various drawbacks of PLA such as its brittleness and processability limitations. In this study, we investigated the effects of varying the molecular weight of the PLA matrix and of two different mixing processes on the blend morphology and, further, on droplet coalescence during shearing. The rheological properties of these blends were investigated and the interfacial properties were analyzed using the Palierne emulsion model. Droplet coalescence was investigated by applying shear flows of 0.05 and 0.20 s{sup −1} at a fixed strain of 60. Subsequently, small amplitude oscillatory shear tests were conducted to investigate changes in the viscoelastic properties. The morphology of the blends was also examined using scanning electron microscope (SEM) micrographs. It was observed that the PBAT droplets were much smaller when twin-screw extrusion was used for the blend preparation. Shearing at 0.05 s{sup −1} induced significant droplet coalescence in all blends, but coalescence and changes in the viscoelastic properties were much more pronounced for the PLA-PBAT blend based on a lower molecular weight PLA. The viscoelastic responses were also somehow affected by the thermal degradation of the PLA matrix during the experiments.

Long Term Performance Study of a Direct Methanol Fuel Cell Fed with Alcohol Blends

Directory of Open Access Journals (Sweden)

Eleuterio Mora

2013-01-01

Full Text Available The use of alcohol blends in direct alcohol fuel cells may be a more environmentally friendly and less toxic alternative to the use of methanol alone in direct methanol fuel cells. This paper assesses the behaviour of a direct methanol fuel cell fed with aqueous methanol, aqueous ethanol and aqueous methanol/ethanol blends in a long term experimental study followed by modelling of polarization curves. Fuel cell performance is seen to decrease as the ethanol content rises, and subsequent operation with aqueous methanol only partly reverts this loss of performance. It seems that the difference in the oxidation rate of these alcohols may not be the only factor affecting fuel cell performance.

The biodiesel is a potential source of alternative fuel which can be used at different proportions with diesel fuel. This study experimentally investigated the effect of blend percentage on diesel engine performance and emission using first generation (soybean) and second generation (waste cooking) biodiesel. The characterization of the biodiesel was done according to ASTM and EN standards and compared with ultralow sulfur diesel (ULSD) fuel. A multi-cylinder test bed engine coupled with electromagnetic dynamometer and 5 gas analyzer were used for engine performance and emission test. The investigation was made using B5, B10 and B15 blends for both biodiesels. The study found that brake power (BP) and brake torque (BT) slightly decreases and brake specific fuel consumption (BSFC) slightly increases with an increase in biodiesel blends ratio. Besides, a significant reduction in exhaust emissions (except NO{sub x} emission) was found for both biodiesels compared to ULSD. Soybean biodiesel showed better engine performance and emissions reduction compared with waste cooking biodiesel. However, NO{sub x} emission for B5 waste cooking biodiesel was lower than soybean biodiesel.

Highlights: • Potential of biodiesel production from crude Moringa oleifera oil. • Characterization of M. oleifera biodiesel and its blend with diesel fuel. • Evaluation of M. oleifera biodiesel blend in a diesel engine. - Abstract: Researchers have recently attempted to discover alternative energy sources that are accessible, technically viable, economically feasible, and environmentally acceptable. This study aims to evaluate the physico-chemical properties of Moringa oleifera biodiesel and its 10% and 20% by-volume blends (B10 and B20) in comparison with diesel fuel (B0). The performance and emission of M. oleifera biodiesel and its blends in a multi-cylinder diesel engine were determined at various speeds and full load conditions. The properties of M. oleifera biodiesel and its blends complied with ASTM D6751 standards. Over the entire range of speeds, B10 and B20 fuels reduced brake power and increased brake specific fuel consumption compared with B0. In engine emissions, B10 and B20 fuels reduced carbon monoxide emission by 10.60% and 22.93% as well as hydrocarbon emission by 9.21% and 23.68%, but slightly increased nitric oxide emission by 8.46% and 18.56%, respectively, compared with B0. Therefore, M. oleifera is a potential feedstock for biodiesel production, and its blends B10 and B20 can be used as diesel fuel substitutes

Full Text Available The sleek of using alternatives to gasoline fuel in internal combustion engines becomes a necessity as the environmental problems of fossil fuels as well as their depleted reserves. This research presents an experimental investigation into a new blended fuel; the effects of n-butanol–methanol–gasoline fuel blends on the performance and pollutant emissions of an SI (spark-ignition engine were examined. Four test fuels (namely 0, 3, 7 and 10 volumetric percent of n-butanol–methanol blends at equal rates, e.g., 0%, 1.5%, 3.5% and 5% for n-butanol and methanol, in gasoline were investigated in an engine speed range of 2600–3400 r/min. In addition, the dual alcohol (methanol and n-butanol–gasoline blends were compared with single alcohol (n-butanol–gasoline blends (for the first time as well as with the neat gasoline fuel in terms of performance and emissions. The experimental results showed that the addition of low content rates of n-butanol–methanol to neat gasoline adversely affects the engine performance and exhaust gas emissions as compared to the results of neat gasoline and single alcohol–gasoline blends; in particular, a reduction in engine volumetric efficiency, brake power, torque, in-cylinder pressure, exhaust gas temperature and CO2 emissions and an increase in concentrations of CO and UHC (unburned hydrocarbons emissions were observed for the dual alcohols. However, higher rates of n-butanol–methanol blended in gasoline were observed to improve the SI engine performance parameters and emission concentration. Oppositely the higher rates of single alcohol–gasoline blends were observed to provide adverse results, e.g., higher emissions and lower performance than those of lower rates of single alcohol. Finally, dual alcohol–gasoline blends could exceed (i.e. provide higher performance and lower emissions single alcohol–gasoline blends and pure gasoline at higher rates (>10 vol.% in the blend and, in turn, it is

Highlights: • Biodiesel produced from palm and Calophyllum oil using trans-esterification process. • Produced biodiesels properties were compared with ASTM D6751 standards. • Engine performance and exhaust emissions were evaluated at high idling conditions. • Idling CO and HC emission was reduced using biodiesel–diesel blends. • For low percentages of biodiesel–diesel blends NO X emission increased negligibly. - Abstract: Rapid depletion of fossil fuels, increasing fossil-fuel price, carbon price, and the quest of low carbon fuel for cleaner environment – these are the reason researchers are looking for alternatives of fossil fuels. Renewable, non-flammable, biodegradable, and non-toxic are some reasons that are making biodiesel as a suitable candidate to replace fossil-fuel in near future. In recent years, in many countries of the world production and use of biodiesel has gained popularity. In this research, biodiesel from palm and Calophyllum inophyllum oil has been produced using the trans-esterification process. Properties of the produced biodiesels were compared with the ASTM D6751 standard: biodiesel standard and testing methods. Density, kinematic viscosity, flash point, cloud point, pour point and calorific value, these are the six main physicochemical properties that were investigated. Both palm biodiesel and Calophyllum biodiesel were within the standard limits, so they both can be used as the alternative of diesel fuel. Furthermore, engine performance and emission parameters of a diesel engine run by both palm biodiesel–diesel and Calophyllum biodiesel–diesel blends were evaluated at high idling conditions. Brake specific fuel consumption increased for both the biodiesel–diesel blends compared to pure diesel fuel; however, at highest idling condition, this increase was almost negligible. Exhaust gas temperatures decreased as blend percentages increased for both the biodiesel–diesel blends. For low blend percentages increase in NO

Highlights: • All of biodiesel blends were given higher BSFC than diesel fuel, except for CIB10. • Diesel produces higher BP and BTE as compared to PB and CIB blends. • CO and HC emissions of PB blends were reduced more than diesel and CIB blends. • PB blends contained lower metal compositions compared to diesel and CIB blends. • PB20 showed lower worn scar surfaces area compared to diesel and biodiesel blends. - Abstract: A running automobile engine produces more friction and wear between its sliding components than an idle one, and thus requires lubrication to reduce this frictional effect. Biodiesel is an alternative diesel fuel that is produced from renewable resources. Energy studies conducted over the last two decades focused on solutions to problems of rising fossil fuel price, increasing dependency on foreign energy sources, and worsening environmental concerns. Palm oil biodiesel is mostly used in Malaysia. This study conducted engine performance and emission tests with a single-cylinder diesel engine fueled with palm and Calophyllum inophyllum biodiesel blends (PB10, PB20, PB30, CIB10, CIB20, and CIB30) at a full-load engine speed range of 1000–2400 rpm, and then compared the results with those of diesel fuel. Friction and wear tests were conducted using the four-ball tester with different temperatures at 40 and 80 kg load conditions and a constant speed of 1800 rpm. The average brake specific fuel consumption increased from 7.96% to 10.15% while operating on 10%, 20%, and 30% blends of palm and C. inophyllum biodiesel. The respective average brake powers for PB20 and PB30 were 9.31% and 12.93% lower compared with that for diesel fuel. PB20 produced relatively lower CO and HC emissions than the diesel and biodiesel blends. Diesel produced low amounts of NO_X emission, and the CIB blend produced a lower frictional coefficient compared with the diesel and PB blends. PB30 showed high average FTP and low average WSD, both of which enhanced

Nuclear energy center finance and ownership considerations

Morris, J.A.; Wilder, R.P.

1980-09-01

Finance and ownership alternatives for a nuclear energy center (NEC) in South Carolina are analyzed in the context of the capital market and tax differences among alternatives. The ownership alternatives considered are (1) the private or private/public joint venture, (2) full public ownership and (3) a hybrid ownership form featuring federal involvement in the initial site development and permit phase, followed by a transition to private ownership. Public ownership is associated with considerably lower out-of-pocket costs than private ownership; the difference between the two, however, is related to subsidies from other parts of society to electricity customers of a publicly owned NEC. The attitudes of participating utilities on ownership forms are examined, with the finding of general strong opposition to increased federal involvement in the electric utility industry through NEC ownership. The conclusion is that the private-private/public joint venture is the preferable ownership form and that public ownership should be employed only if the private sector fails to respond to future energy demand

Tsita, Katerina G.; Pilavachi, Petros A.

2012-01-01

This paper evaluates alternative fuels for the Greek road transport sector, using the Analytic Hierarchy Process. Seven different alternatives of fuel mode are considered in this paper: internal combustion engine (ICE) and its combination with petroleum and 1st and 2nd generation biofuels blends, fuel cells, hybrid vehicles, plug-in hybrids and electric vehicles. The evaluation of alternative fuel modes is performed according to cost and policy aspects. In order to evaluate each alternative fuel, one base scenario and ten alternative scenarios with different weight factors selection per criterion are presented. After deciding the alternative fuels’ scoring against each criterion and the criteria weights, their synthesis gives the overall score and ranking for all ten alternative scenarios. It is concluded that ICE blended with 1st and 2nd generation biofuels are the most suitable alternative fuels for the Greek road transport sector. - Highlights: ► Alternative fuels for the Greek road transport sector have been evaluated. ► The method of the AHP was used. ► Seven different alternatives of fuel mode are considered. ► The evaluation is performed according to cost and policy aspects. ► The ICE with 1st and 2nd generation biofuels are the most suitable fuels.

2016-01-01

Highlights: • Water-containing ABE (acetone–butanol–ethanol) was used an alternative fuel. • Water-containing ABE and gasoline blends were investigated in an SI engine. • Water-containing ABE and gasoline blends can enhance engine torque. • Water-containing ABE and gasoline blends can reduce CO, UHC and NO_x emissions. - Abstract: Bio-butanol has proved to be a promising alternative fuel in recent years; it is typically produced from ABE (acetone–butanol–ethanol) fermentation from non-edible biomass feedstock. The high costs for dehydration and recovery from dilute fermentation broth have so far prohibited bio-butanol’s use in internal combustion engines. There is an interesting in studying the intermediate fermentation product, i.e. water-containing ABE as a potential fuel. However, most previous studies covered the use of water-containing ABE–diesel blends. In addition, previous studies on SI engines fueled with ABE did not consider the effect of water. Therefore, the evaluation of water-containing ABE gasoline blends in a port fuel-injected spark-ignition (SI) engine was carried out in this study. Effect of adding ABE and water into gasoline on combustion, performance and emissions characteristics was investigated by testing gasoline, ABE30, ABE85, ABE29.5W0.5 and ABE29W1 (29 vol.% ABE, 1 vol.% water and 70 vol.% gasoline). In addition, ABE29W1 was compared with gasoline under various equivalence ratios (Φ = 0.83–1.25) and engine loads (3 and 5 bar BMEP). It was found that ABE29W1 generally had higher engine toque (3.1–8.2%) and lower CO (9.8–35.1%), UHC (27.4–78.2%) and NO_x (4.1–39.4%) than those of gasoline. The study indicated that water-containing ABE could be used in SI engines as an alternative fuel with good engine performance and low emissions.

Paun, Irina Alexandra; Ion, Valentin; Moldovan, Antoniu; Dinescu, Maria

2011-01-01

In this work, we show successful use of matrix-assisted pulsed laser evaporation (MAPLE) for obtaining thin films of PEG:PLGA blends, in the view of their use for controlled drug delivery. In particular, we investigate the influence of the blending ratios on the characteristics of the films. We show that the roughness of the polymeric films is affected by the ratio of each polymer within the blend. In addition, we perform Fourier transformed infrared spectroscopy (FTIR) measurements and we find that the intensities ratios of the infrared absorption bands of the two polymers are consistent with the blending ratios. Finally, we assess the optical constants of the polymeric films by spectroscopic ellipsometry (SE). We point out that the blending ratios exert an influence on the optical characteristics of the films and we validate the SE results by atomic force microscopy and UV-vis spectrophotometry. In all, we stress that the ratios in which the two polymers are blended have significant impact on the morphology, chemical structure and optical characteristics of the polymeric films deposited by MAPLE.

Alternate aviation fuels for military or commercial use are required to satisfy MIL-DTL-83133F(2008) or ASTM D 7566 (2010) standards, respectively, and are classified as "drop-in" fuel replacements. To satisfy legacy issues, blends to 50% alternate fuel with petroleum fuels are certified individually on the basis of processing and assumed to be feedstock agnostic. Adherence to alternate fuels and fuel blends requires "smart fueling systems" or advanced fuel-flexible systems, including combustors and engines, without significant sacrifice in performance or emissions requirements. This paper provides preliminary performance (Part A) and emissions and particulates (Part B) combustor sector data. The data are for nominal inlet conditions at 225 psia and 800 F (1.551 MPa and 700 K), for synthetic-paraffinic-kerosene- (SPK-) type (Fisher-Tropsch (FT)) fuel and blends with JP-8+100 relative to JP-8+100 as baseline fueling. Assessments are made of the change in combustor efficiency, wall temperatures, emissions, and luminosity with SPK of 0%, 50%, and 100% fueling composition at 3% combustor pressure drop. The performance results (Part A) indicate no quantifiable differences in combustor efficiency, a general trend to lower liner and higher core flow temperatures with increased FT fuel blends. In general, emissions data (Part B) show little differences, but with percent increase in FT-SPK-type fueling, particulate emissions and wall temperatures are less than with baseline JP-8. High-speed photography illustrates both luminosity and combustor dynamic flame characteristics.

2011-01-01

Full Text Available Biofuels like ethanol, biodiesel, have attracted attention of people worldwide and proved to be the successful fuel alternates to petroleum products. In the present investigation, the effect of supercharging is studied on the performance of a direct injection diesel engine using ethanol diesel blends with palm stearin methyl ester as additive. The performance of the engine is evaluated in terms of brake specific fuel consumption, thermal efficiency, exhaust gas temperature, un-burnt hydrocarbons, carbon monoxide, nitrogen oxide emissions, and smoke opacity. The investigation results showed that the output and torque performance of the engine with supercharging was improved in comparison with naturally aspirated engine. It is observed that the brake thermal efficiency of ethanol diesel blends was higher than that of diesel. With supercharging brake thermal efficiency is further improved. Brake specific fuel consumption of ethanol, ester and diesel blends are lower compared with diesel at full load. Further reduction in brake specific fuel consumption is observed with supercharging. Nitrous oxide formation seems to decrease with ethanol, ester and diesel blends. Hydrocarbons and carbon monoxide emissions are more with ethanol, ester and diesel blends with supercharging slight reduction in those values are observed.

2000-01-01

An experimental investigation was conducted to determine the emissions characteristics of higher alcohols and gasoline (UTG96) blends. While lower alcohols (methanol and ethanol) have been used in blends with gasoline, very little work has been done or reported on higher alcohols (propanol, butanol and pentanol). Comparisons of emissions and fuel characteristics between higher alcohol/gasoline blends and neat gasoline were made to determine the advantages and disadvantages of blending higher alcohols with gasoline. All tests were conducted on a single-cylinder Waukesha Cooperative Fuel Research engine operating at steady state conditions and stoichiometric air-fuel (A/F) ratio. Emissions test were conducted at the optimum spark timing-knock limiting compression ratio combination for the particular blend being tested. The cycle emission [mass per unit time (g/h)] of CO, CO 2 and organic matter hydrocarbon equivalent (OMHCE) from the higher alcohol/gasoline blends were very similar to those from neat gasoline. Cycle emissions of NO x from the blends were higher than those from neat gasoline. However, for all the emissions species considered, the brake specific emissions (g/kW h) were significantly lower for the higher alcohol/gasoline blends than for neat gasoline. This was because the blends had greater resistance to knock and allowed higher compression ratios, which increased engine power output. The contribution of alcohols and aldehydes to the overall OMHCE emissions was found to be minimal. Cycle fuel consumption (g/h) of higher alcohol/gasoline blends was slightly higher than with neat gasoline due to the lower stoichiometric A/F ratios required by the blends. However, the brake specific fuel consumption (g/kW h) for the blends was significantly lower than that for neat gasoline. (Author)

An economic theory of Islamic finance

Directory of Open Access Journals (Sweden)

Mabid Ali Al-Jarhi

2017-07-01

Full Text Available Purpose - This paper aims to provide an economic rationale for Islamic finance. Design/methodology/approach - Its methodology is simple. It starts with listing the contributions to economic analysis relevant to the required rationale in the theories of banking, finance, price, money and macroeconomics, to identify the main rationale for Islamic finance. A concise description of the author’s model for an Islamic economic system, within which Islamic finance can be operational, is provided. Findings - The paper finds distinct advantages of Islamic finance, when properly applied within the author’s model. Islamic finance can therefore be a candidate as a reform agenda for conventional finance. It opens the door for significant monetary reform in currently prevalent economic systems. Research limitations/implications - The first limitation of the paper is that the distinct benefits of Islamic finance are all of macroeconomic types which are external to Islamic banking and finance institutions. They are therefore not expected to motivate such institutions to apply Islamic finance to the letter, without regulators interference to ensure strict application. The second limitation is the necessity to set up enabling institutional and regulatory arrangements for Islamic finance. Originality/value - The results are unique as they challenge the received doctrine and provide non-religious rationale for Islamic finance.

Wu, Zichao

2000-10-01

This thesis presents the development of high-performance blended cements from industrial by-products. To overcome the low-early strength of blended cements, several chemicals were studied as the activators for cement hydration. Sodium sulfate was discovered as the best activator. The blending proportions were optimized by Taguchi experimental design. The optimized blended cements containing up to 80% fly ash performed better than Type I cement in strength development and durability. Maintaining a constant cement content, concrete produced from the optimized blended cements had equal or higher strength and higher durability than that produced from Type I cement alone. The key for the activation mechanism was the reaction between added SO4 2- and Ca2+ dissolved from cement hydration products.

Full Text Available Public-private partnerships (PPP can be employed to provide public rental housing for young graduates, which has been urgent to achieve social sustainability in China. However, few studies have been conducted to investigate the financing structure of PPPs, particularly the ratio of private investment, which is important in initiating a PPP project. This study develops a robust model to determine the financing structure through considering the uncertainties in operation. A case study in Hangzhou demonstrates the process of the model. The relevant findings provide private investors and the local government with effective references for negotiating the financing structure of a PPP project.

Marlim project finance; 'Project finance' de Marlim

Energy Technology Data Exchange (ETDEWEB)

D' Almeida, Albino Lopes [PETROBRAS, Rio de Janeiro, RJ (Brazil)

2004-07-01

Project Finance is often used worldwide to raise the funds to develop big projects, particularly in the area of power and infra-structure. It is designed to support a singular project and a specific purpose company is created to obtain the financing. The debt payment is secured by the enterprise's cash flow, avoiding real guarantee requirements. The lenders receive the future revenues and the property of the assets to be built. The risks are mitigated by agreements exhaustively negotiated among the parties. One of the most important Project Finances performed in Brazil is the Marlim Project, structured in order to complete the development of the Marlim oil field. This is the biggest Brazilian oil field, producing more than 500,000 barrels a day, almost 35% of the national production. This paper presents the general concepts related to this type of financing and general information about the project, including its structuring, negotiation and closing. The total commitment reaches US$ 1.5 billion obtained in both domestic and international markets through equity, bridge loan, bonds and commercial papers. Its whole life is 10 years, using 2 special purpose companies in its configuration. (author)

Emission Characteristics and Egr Application of Blended Fuels with Bdf and Oxygenate (dmm) in a Diesel Engine

Science.gov (United States)

Choi, Seung-Hun; Oh, Young-Taig

In this study, the possibility of biodiesel fuel and oxygenated fuel (dimethoxy methane ; DMM) was investigated as an alternative fuel for a naturally aspirated direct injection diesel engine. The smoke emission of blending fuel (biodiesel fuel 90vol-% + DMM 10vol-%) was reduced approximately 70% at 2500rpm, full load in comparison with the diesel fuel. But, engine power and brake specific energy consumption showed no significant differences. But, NOx emission of biodiesel fuel and DMM blended fuel increased compared with commercial diesel fuel due to the oxygen component in the fuel. It was needed a NOx reduction counter plan that EGR method was used as a countermeasure for NOx reduction. It was found that simultaneous reduction of smoke and NOx emission was achieved with BDF (95 vol-%) and DMM (5 vol-%) blended fuel and cooled EGR method (15%).

2018-06-01

Biodiesels have gained much popularity because they are cleaner alternative fuels and they can be used directly in diesel engines without modifications. In this paper, a brief review of the key studies pertaining to the engine performance and exhaust emission characteristics of diesel engines fueled with biodiesel blends, exhaust aftertreatment systems, and low-temperature combustion technology is presented. In general, most biodiesel blends result in a significant decrease in carbon monoxide and total unburned hydrocarbon emissions. There is also a decrease in carbon monoxide, nitrogen oxide, and total unburned hydrocarbon emissions while the engine performance increases for diesel engines fueled with biodiesels blended with nano-additives. The development of automotive technologies, such as exhaust gas recirculation systems and low-temperature combustion technology, also improves the thermal efficiency of diesel engines and reduces nitrogen oxide and particulate matter emissions.

Financing models for HTR plants: Co-financing, counter trade, joint ventures

Bogen, J.; Stoelzl, D.

1987-01-01

Structure and volume of investment cost for HTR nuclear power plants are different in comparison to other types of nuclear power plants. Even if the share of local participation is in comparable order of magnitude to other nuclear power plants, the required technical infrastructure for HTR plants is more suitable for existing and still practised technologies in countries which are in development processes. These HTR specific features offer special possibilities in HTR project financing. Various models are discussed in respect of the special HTR situation. Even if it is not possible to point out in a general manner the best solution - due to national, local and time dependant situations - this paper discusses the HTR specific impacts to buyer's credit financing, supplier's credit financing, barter trades or joint ventures and combined financing.

Surface Water Mapping from Suomi NPP-VIIRS Imagery at 30 m Resolution via Blending with Landsat Data

Directory of Open Access Journals (Sweden)

Chang Huang

2016-07-01

Full Text Available Monitoring the dynamics of surface water using remotely sensed data generally requires both high spatial and high temporal resolutions. One effective and popular approach for achieving this is image fusion. This study adopts a widely accepted fusion model, the Enhanced Spatial and Temporal Adaptive Reflectance Fusion Model (ESTARFM, for blending the newly available coarse-resolution Suomi NPP-VIIRS data with Landsat data in order to derive water maps at 30 m resolution. The Pan-sharpening technique was applied to preprocessing NPP-VIIRS data to achieve a higher-resolution before blending. The modified Normalized Difference Water Index (mNDWI was employed for mapping surface water area. Two fusion alternatives, blend-then-index (BI or index-then-blend (IB, were comparatively analyzed against a Landsat derived water map. A case study of mapping Poyang Lake in China, where water distribution pattern is complex and the water body changes frequently and drastically, was conducted. It has been revealed that the IB method derives more accurate results with less computation time than the BI method. The BI method generally underestimates water distribution, especially when the water area expands radically. The study has demonstrated the feasibility of blending NPP-VIIRS with Landsat for achieving surface water mapping at both high spatial and high temporal resolutions. It suggests that IB is superior to BI for water mapping in terms of efficiency and accuracy. The finding of this study also has important reference values for other blending works, such as image blending for vegetation cover monitoring.

Biodegradability Study of the Blend Film of High Density Polyethylene and Poly(lactic acid Disposable Packages Flake

2016-03-01

Full Text Available One of the major concerns of using a non-biodegradable polymer product is its disposal at the end of its life cycle. Development of biodegradable plastics promises an alternative solution to combat this problem. Blending of poly(lactic acid with non-biodegradable polymers is a practical and economical method for modifying the biodegradability properties of non-biodegradable polymers. In this study, soil biodegradability of the blends of high density polyethylene (HDPE and variable amounts of recycled poly(lactic acid (r-PLA plastic flakes at 0, 5, 10, 20, 30, 40 and 50 wt% was studied. The behavior of the force-elongation profile of the blends having r-PLA content of lower than 30 wt% was approximately the same as that of pure HDPE while, it was completely different for the other blends. Tearing force and elongation-at-yield-point of the blends films with the 20 to 50 wt% r-PLA were decreased significantly after 60 days of soil biodegradability test. Morphological study showed that biodegradability of the blend films at surface of the samples (deep pores and grooves was increased with extended biodegradability time and higher r-PLA content, while, this variation was significant for the blend films of more than 20 wt% r-PLA content. Thermal properties evaluation by differential scanning calorimetry (DSC curves indicated that the glass transition temperature and enthalpy peaks during the heating stage were eliminated with increasing the biodegradability testing time. Also, reduction in the crystallinity degree of the r-PLA component with increasing the biodegradability testing time coincided with the earlier results.

Structural characterization of HDPE/LLDPE blend-based nano composites obtained by different blending sequence

International Nuclear Information System (INIS)

Passador, Fabio R.; Ruvolo Filho, Adhemar; Pessan, Luiz A.

2011-01-01

The blending sequence affects the morphology formation of the nanocomposites. In this work, the blending sequences were explored to determine its influence in the rheological behavior of HDPE/LLDPE/OMMT nanocomposites. The nanocomposites were obtained by melt-intercalation using a mixture of LLDPE-g-MA and HDPE-g-MA as compatibilizer system in a torque rheometer at 180 deg C and five blending sequences were studied. The materials structures were characterized by wide angle X-ray diffraction (WAXD) and by rheological properties. The nanoclay's addition increased the shear viscosity at low shear rates, changing the behavior of HDPE/LLDPE matrix to a Bingham model behavior with an apparent yield stress. Intense interactions were obtained for the blending sequence where LLDPE and/or LLDPE-g-MA were first reinforced with organoclay since the intercalation process occurs preferentially in the amorphous phase.

Taking into account feasibility, political and technical criteria, three Latin American countries were selected as study populations: Mexico, Nicaragua and Peru. The methodology had two main phases. In the first phase, the study referred to secondary sources of data and documents to obtain information about the following variables: type of decentralization implemented, source of finance, funds of financing, providers, final use of resources and mechanisms for resource allocation. In the second phase, the study referred to primary data collected in a survey of key personnel from the health sectors of each country. The trends and evidence reported in all five financing indicators may identify major weaknesses and strengths in health financing. Weaknesses: a lack of human resources trained in health economics who can implement changes, a lack of financial resource independence between the local and central levels, the negative behavior of the main macro-economic variables, and the difficulty in developing new financing alternatives. Strengths: the sharing between the central level and local levels of responsibility for financing health services, the implementation of new organizational structures for the follow-up of financial changes at the local level, the development and implementation of new financial allocation mechanisms taking as a basis the efficiency and equity principles, new technique of a per-capita adjustment factor corrected at the local health needs, and the increase of financing contributions from households and local levels of government.

Bio-butanol is typically produced by acetone-butanol-ethanol (ABE) fermentation, however, the recovery of bio-butanol from the ABE mixture involves high costs and energy consumption. Hence it is of interest to study the intermediate fermentation product, i.e. ABE, as a potentially alternative fuel. In this study, an experimental investigation of the performance, combustion and emission characteristics of a port fuel-injection SI engine fueled with ABE-gasoline blends was carried out. By testing different ABE-gasoline blends with varying ABE content (0 vol%, 10 vol%, 30 vol% and 60 vol% referred to as G100, ABE10, ABE30 and ABE60), ABE formulation (A:B:E of 1:8:1, 3:6:1 and 5:4:1 referred to as ABE(181), ABE(361) and ABE(541)), and water content (0.5 vol% and 1 vol% water referred to as W0.5 and W1), it was found that ABE(361)30 performed well in terms of engine performance and emissions, including brake thermal efficiency (BTE), brake specific fuel consumption (BSFC), carbon monoxide (CO), unburned hydrocarbons (UHC) and nitrogen oxides (NO_x) emissions. Then, ABE(361)30 was compared with conventional fuels, including E30, B30 (30 vol% ethanol or butanol blended with gasoline) and pure gasoline (G100) under various equivalence ratios and engine loads. Overall, a higher BTE (0.2–1.4%) and lower CO (1.4–4.4%), UHC (0.3–9.9%) and NO_x (4.2–14.6%) emissions were observed for ABE(361)30 compared to those of G100 in some cases. Therefore, ABE could be a good alternative fuel to gasoline due to the environmentally benign manufacturing process (from non-edible biomass feedstock and without a recovery process), and the potential to improve energy efficiency and reduce pollutant emissions. - Highlights: • ABE (acetone-butanol-ethanol) was used as a green alternative fuel. • ABE-gasoline blends with various ratios of ABE, ABE component and water were test. • Combustion, performance and emissions characteristics were investigated. • Adding ABE into

Full Text Available For the past few decades, Islamic finance has imposed itself as a viable alternative / complementary system to the long existing conventional financial system. Nevertheless, recent research has claimed that Islamic finance as it is currently practice, does not promote economic growth. Hence, the objective of this study is to empirically test this claim, by examining the potential effect of Islamic finance in the specific form of Sukuk issuance on the economic growth represented by three proxies, namely, Gross Domestic Product (GDP, Gross Capital Formation (GDP and trade activities. The data covers not only GCC (Gulf Cooperation Council, but also other countries including Malaysia, Indonesia, Turkey, Pakistan, Singapore, China, Brunei, Kazakhstan, Germany, United Kingdom (UK, The Gambia and France. The data were collected from the Islamic Finance Information Services (IFIS and the World Bank databases, and were subsequently analysed through Toda and Yamamoto Granger Non Causality test. Accordingly, the findings indicated that the Sukuk issuance had an influence on the GDP and GCF only when all the countries were pulled together, otherwise no effect was identified for Saudi Arabia and the GCC.

2004-01-01

This paper presents the results of investigations carried out in studying the fuel properties of karanja methyl ester (KME) and its blend with diesel from 20% to 80% by volume and in running a diesel engine with these fuels. Engine tests have been carried out with the aim of obtaining comparative measures of torque, power, specific fuel consumption and emissions such as CO, smoke density and NO x to evaluate and compute the behaviour of the diesel engine running on the above-mentioned fuels. The reduction in exhaust emissions together with increase in torque, brake power, brake thermal efficiency and reduction in brake-specific fuel consumption made the blends of karanja esterified oil (B20 and B40) a suitable alternative fuel for diesel and could help in controlling air pollution.

Martins, Andréa Bercini; Santana, Ruth Marlene Campomanes

2016-01-01

In this work, polypropylene/thermoplastic starch (PP/TPS) blends were prepared as an alternative material to use in disposable packaging, reducing the negative polymeric environmental impact. Unfortunately, this material displays morphological characteristics typical of immiscible polymer blends and a compatibilizer agent is needed. Three different carboxyl acids: myristic (C14), palmitic (C16) and stearic acids (C18) were used as natural compatibilizer agent (NCA). The effects of NCA on the mechanical, physical, thermal and morphological properties of PP/TPS blends were investigated and compared against PP/TPS with and without PP-grafted maleic anhydride (PPgMA). When compared to PP/TPS, blends with C18, PPgMA and C14 presented an improvement of 25, 22 and 17% in tensile strength at break and of 180, 194 and 259% in elongation at break, respectively. The highest increase, 54%, in the impact strength was achieved with C14 incorporation. Improvements could be seen, through scanning electron microscopy (SEM) images, in the compatibility between the immiscible components by acids incorporation. These results showed that carboxylic acids, specifically C14, could be used as compatibilizer agent and could substitute PPgMA. Copyright © 2015 Elsevier Ltd. All rights reserved.

Effects of Engine Cooling Water Temperature on Performance and Emission Characteristics of a Ci Engine Operated with Biofuel Blend

Directory of Open Access Journals (Sweden)

Abul Hossain

2017-03-01

Full Text Available The temperature of the coolant is known to have significant influence on engine performance and emissions. Whereas existing literature describes the effects of coolant temperature in engines using fossil derived fuels, very few studies have investigated these effects when biofuel is used. In this study, Jatropha oil was blended separately with ethanol and butanol. It was found that the 80% jatropha oil + 20% butanol blend was the most suitable alternative, as its properties were closest to that of fossil diesel. The coolant temperature was varied between 50°C and 95°C. The combustion process enhanced for both diesel and biofuel blend, when the coolant temperature was increased. The carbon dioxide emissions for both diesel and biofuel blend were observed to increase with temperature. The carbon monoxide, oxygen and lambda values were observed to decrease with temperature. When the engine was operated using diesel, nitrogen oxides emissions correlated in an opposite manner to smoke opacity; however, nitrogen oxides emissions and smoke opacity correlated in an identical manner for biofuel blend. Brake specific fuel consumption was observed to decrease as the temperature was increased and was higher on average when the biofuel was used. The study concludes that both biofuel blend and fossil diesel produced identical correlations between coolant temperature and engine performance. The trends of nitrogen oxides and smoke emissions with cooling temperatures were not identical to fossil diesel when biofuel blend was used in the engine.

Study of performance and emission characteristics of a partially coated LHR SI engine blended with n-butanol and gasoline

Directory of Open Access Journals (Sweden)

Nitesh Mittal

2013-09-01

Full Text Available To meet the present requirements of the automotive industry, there is continuous search to improve the performance, exhaust emission, and life of the IC engines. The meet the first two challenges, researchers are working both on newer engine technologies and fuels. Some of the published work indicates that coating on the combustion surface of the engine with ceramic material results in improved performance and reduced emission levels when fueled with alternate fuel blended fuels, and this serves as a base for this work. Normal-Butanol has molecular structure that is adaptable to gasoline, and it is considered as one of the alternative fuels for SI engines. Blending butanol with gasoline changes the properties of the fuel and alters the engine performance and emission characteristics. This is because heat which is released at a rate as a result of combustion of the compressed air–fuel mixture in the combustion chamber gets changed with respect to change fuel properties, air fuel ratio, and engine speed. An experimental investigation is carried out on a partially insulated single cylinder SI engine to study the performance and emission characteristics when fueled with two different blends of butanol and gasoline. The cylinder head surface and valves are coated with a ceramic material consisting of Zirconium dioxide (ZrO2 with 8% by weight of Yttrium Oxide (Y2O3 to a thickness of 0.3 mm by plasma spray method. Two different fuel blends containing 10% and 15% by volume of butanol in Gasoline are tested on an engine dynamometer using the uncoated and ceramic coated engines. The results strongly indicate that combination of ceramic coated engine and butanol gasoline blended fuel has potential to improve the engine performance.

Polyethylene/hydrophilic polymer blends for biomedical applications.

1987-01-01

Polyethylene blends with poly(2-hydroxyethyl methacrylate) [poly(HEMA)] or poly(2,3-dihydroxypropyl methacrylate) [poly(DHPMA)] were prepared by swelling polyethylene with HEMA or 2,3-epoxypropyl methacrylate (EPMA) and by polymerization of the respective monomers. Poly(EPMA) in blends was hydrolysed to poly(DHPMA) with acetic acid. The blends had similar surface and bulk compositions. Swelling with water and surface wettability were proportional to the content of the hydrophilic component; at the same content the polyethylene/poly(DHPMA) blends appeared more hydrophilic than those of polyethylene/poly(HEMA). Thrombus formation in contact with blood examined ex vivo and in vivo was considerably slower on the blends than on unmodified polyethylene. The tests indicated optima in composition; the best biological response was achieved with the blends containing about 14% poly(HEMA) or 16% poly(DHPMA).

Full Text Available The increasing demands of petroleum fuels due to the rapid development automotive society coupled with the environmental pollution issues have inspired the efforts on exploring alternative fuels for internal combustion engines. Bioethanol obtained from biomass and bioenergy crops has been proclaimed as one of the feasible alternative to gasoline. In this study, the effect of gasoline–ethanol–methanol (GEM ternary blend on the emission characteristics of petrol engine was studied. Three different fuel blends, namely, E0 (gasoline, G75E21M4 (75% gasoline, 21% hydrous ethanol and 4% methanol and E25 (25% anhydrous ethanol and 75% gasoline were tested in a 1.3-l K3-VE spark-ignition engine. The results indicate that, when G75E21M4 fuel blend was used, a significant drop in CO, CO2, NOx and HC emissions by about 42%, 15%, 7% and 5.2% compared to E0, respectively. Moreover, the emission results for G75E21M4 are marginally lower than E25 whereas; HC emission was slightly higher than E25.

Alternative measure of multifractal content and its application in finance

International Nuclear Information System (INIS)

2016-01-01

An alternative method for analysis of multifractal properties of time series is provided. We propose a new kind of measure of multifractality strength which takes into account the behavior of multifractal profile of the generalized Hurst exponent h(q) for all moment orders q and is not limited only to the edge values of moment orders describing the scaling properties of smallest and largest fluctuations of a given signal in multifractal detrended fluctuation analysis (MFDFA). The meaning of this new measure is clarified and its performance is investigated for synthetic multifractal data and also for examples of real signals originating from stock markets. We provide also the interpretation of the alternative method following the scaling law that links together the geometric mean value of properly normalized standard q-fluctuation function F"2(q; τ) in MFDFA and the window length τ in which detrending of a signal is performed. We discuss in this context the influence of multifractal bias on the new measure, i.e., the influence of effects which give similar observed features as multiscaling properties however, are not generated by temporal multiscaling autocorrelation in data. It is shown that the proposed alternative measure is robust in some extend to nonstationarity in data. As a result one may avoid problems with interpretation of multifractal profile h(q) encountered in many real nonstationary signals investigated in the standard way.

Shin, Boo Young; Han, Do Hung

2017-11-01

The aim of this study was to observe changes in the viscoelastic properties of PLA/PCL (80/20) blends produced using different compatibilization methods. Reactive extrusion and high-energy radiation methods were used for blend compatibilization. Storage and loss moduli, complex viscosity, transient stress relaxation modulus, and tan δ of blends were analyzed and blend morphologies were examined. All compatibilized PLA/PCL blends had smaller dispersed particle sizes than the non-compatibilized blend, and well compatibilized blends had finer morphologies than poorly compatibilized blends. Viscoelastic properties differentiated well compatibilized and poorly compatibilized blends. Well compatibilized blends had higher storage and loss moduli and complex viscosities than those calculated by the log-additive mixing rule due to strong interfacial adhesion, whereas poorly compatibilized blends showed negative deviations due to weak interfacial adhesion. Moreover, well compatibilized blends had much slower stress relaxation than poorly compatibilized blends and didn't show tan δ plateau region caused by slippage at the interface between continuous and dispersed phases.

Nasr, G.M.; Madani, M.

2005-01-01

A study has been made on blend ratios of natural rubber (NR) and acrylonitrile butadiene rubber (NBR) that are loaded with general purpose furnace (GPE) carbon black and irradiated at different gamma radiation doses. It was fount that the mechanical properties of such blend are highly affected by γ- irradiation dose and the composition ratios of its constituents. The elongation at break for blends was found to increase slightly with increasing NBR loafing which is mainly due to the stiffness of blending matrix formation between NR and GPF carbon black particles. The hysteresis loss, extension ratio and shape factor have been calculated for the different un-irradiated and irradiated samples

Qasim, Muhammad; Ansari, Tariq Mahmood; Hussain, Mazhar

2017-10-18

The waste tyre and waste cooking oils have a great potential to be used as alternative fuels for diesel engines. The aim of this study was to convert light fractions of pyrolysis oil derived from Pakistani waste vehicle tyres and waste soybean oil methyl esters into valuable fuel and to reduce waste disposal-associated environmental problems. In this study, the waste tyre pyrolysis liquid (light fraction) was collected from commercial tyre pyrolysis plant and biodiesel was prepared from waste soybean oil. The fuel blends (FMWO10, FMWO20, FMWO30, FMWO40 and FMWO50) were prepared from a 30:70 mixture of waste tyre pyrolysis liquid and waste soybean oil methyl esters with different proportions of mineral diesel. The mixture was named as the fuel mixture of waste oils (FMWO). FT-IR analysis of the fuel mixture was carried out using ALPHA FT-IR spectrometer. Experimental investigations on a diesel engine were carried out with various FMWO blends. It was observed that the engine fuel consumption was marginally increased and brake thermal efficiency was marginally decreased with FMWO fuel blends. FMWO10 has shown lowest NOx emissions among all the fuel blends tested. In addition, HC, CO and smoke emissions were noticeably decreased by 3.1-15.6%, 16.5-33.2%, and 1.8-4.5%, respectively, in comparison to diesel fuel, thereby qualifying the blends to be used as alternative fuel for diesel engines.

Highlights: • Waste separation should take place at high purity. • Developed a novel, alternative separation method, where the separation occurred in a melted state by centrifugal forces. • Possibility of separation two different plastics into neat fractions. • High purity fractions were established at granulates and also at prefabricated blend. • Results were verified by DSC, optical microscopy and Raman spectroscopy. - Abstract: In order to upgrade polymer waste during recycling, separation should take place at high purity. The present research was aimed to develop a novel, alternative separation opportunity, where the polymer fractions were separated by centrifugal force in melted state. The efficiency of the constructed separation equipment was verified by two immiscible plastics (polyethylene terephthalate, PET; low density polyethylene, LDPE), which have a high difference of density, and of which large quantities can also be found in the municipal solid waste. The results show that the developed equipment is suitable not only for separating dry blended mixtures of PET/LDPE into pure components again, but also for separating prefabricated polymer blends. By this process it becomes possible to recover pure polymer substances from multi-component products during the recycling process. The adequacy of results was verified by differential scanning calorimetry (DSC) measurement as well as optical microscopy and Raman spectroscopy

The developments of both biodiesel and emulsified diesel are being driven by the need for reducing emissions from diesel engines and saving energy. Artificial chemical additives are also being used in diesel engines for increasing their combustion efficiencies. But the effects associated with the use of emulsified additive/biodiesel/diesel blends in diesel engines have never been assessed. In this research, the premium diesel fuel (PDF) was used as the reference fuel. A soy-biodiesel was selected as the test biodiesel. A biosolution made of 96.5 wt % natural organic enzyme-7F (NOE-7F) and 3.5 wt % water (NOE-7F water) was used as the fuel additive. By adding additional 1 vol % of surfactant into the fuel blend, a nanotechnology was used to form emulsified biosolution/soy-biodiesel/PDF blends for fueling the diesel engine. We found that the emulsified biosolution/soy-biodiesel/PDF blends did not separate after being kept motionless for 30 days. The above stability suggests that the above combinations are suitable for diesel engines as alternative fuels. Particularly, we found that the emulsified biosolution/soy-biodiesel/PDF blends did have the advantage in saving energy and reducing the emissions of both particulate matters (PM) and polycyclic aromatic hydrocarbons (PAHs) from diesel engines as compared with PDF, soy-biodiesel/PDF blends, and emulsified soy-biodiesel/ PDF blends. The results obtained from this study will provide useful approaches for reducing the petroleum reliance, pollution, and global warming. However, it should be noted that NO(x) emissions were not measured in the present study which warrants the need for future investigation.

Highlights: • Properties limitation of biodiesel has been overcome using multiple biodiesel blends. • New biodiesel was developed using biodiesel–biodiesel optimum blend. • Engine performance and emission was tested with the newly developed biodiesels. • New biodiesels showed better engine performance than other tested fuels. - Abstract: Fossil fuel depletion, global warming with rapid changes in climate, and increases in oil prices have motivated scientists to search for alternative fuel. Biodiesel can be an effective solution despite some limitations, such as poor fuel properties and engine performance. From this perspective, experiments were carried out to improve fuel properties and engine performance by using a binary blend of palm and coconut biodiesel at an optimized ratio. MATLAB optimization tool was used to determine this blend ratio. A new biodiesel was developed and represented by PC (optimum blend of palm and coconut biodiesel). Engine performance and emission were tested under a full load at variable speed condition by using a 20% blend of each biodiesel with petroleum diesel, and the results were compared with petroleum diesel under both turbocharged and non-turbocharged conditions. PC20 (blend of 20% PC biodiesel and 80% petroleum diesel) showed the highest engine power with lower brake-specific fuel consumption than the other tested fuels in the presence of a turbocharger. The emissions of PC20 were lower than those of all other tested fuels. The experimental analysis reveals that PC showed superior performance and emission over palm biodiesel blend

Kjærgaard, Annemette

While blended learning combines online and face-to-face teaching, research on blended learning has primarily focused on the role of technology and the opportunities it creates for engaging students. Less focus has been put on face-to-face activities in blended learning. This paper argues...... that it is not only the online activities in blended learning that provide new opportunities for rethinking pedagogy in higher education, it is also imperative to reconsider the face-to-face activities when part of the learning is provided online. Based on a review of blended learning in business and management...... education, we identify what forms of teaching and learning are suggested to take place face-to-face when other activities are moved online. We draw from the Community of Inquiry framework to analyze how face-to-face activities contribute to a blended learning pedagogy and discuss the implications...

BLENDED LEARNING STRATEGY IN TEACHER TRAINING PROGRAMS

Directory of Open Access Journals (Sweden)

Marian F. Byrka

2017-12-01

Full Text Available The article examines the implementation of blended learning strategy in teacher training programs as an innovation in online learning. The blended learning idea comes from blending elements which use online technology with more traditional face-to-face teaching in the same course. The article analyses teacher training programs offered by Chernivtsi Regional Institute of Postgraduate Pedagogical Education. Additional data were gathered through a questionnaire administered to teachers who attended training courses. The characteristics of blended learning strategy, its benefits and limitations for teacher training are supported by a review of literature. The article closes with the comparison of curriculum components (content delivery, learner activities, materials, and required competences between traditional and blended learning teacher training programs. Having obvious benefits in teacher training programs, the implementation of blended learning strategy sets some additional requirements to a learner, as well as to course instructors and lectors.

Miyazaki, Yasunori; Uchino, Tomonobu; Kagawa, Yoshiyuki

2014-01-01

On dispensing powdered antineoplastic medicines, it is important to prevent cross-contamination and environmental exposure. Recently, we developed a method for blending powdered medicine in a disposable ointment container using a planetary centrifugal mixer. The disposable container prevents cross-contamination. In addition, environmental exposure associated with washing the apparatus does not arise because no blending blade is used. In this study, we aimed to confirm the uniformity of the mixture and weight loss of medicine in the blending procedure. We blended colored lactose powder with Leukerin(®) or Mablin(®) powders using the new method and the ordinary pestle and mortar method. Then, the blending state was monitored using image analysis. Blending variables, such as the blending ratio (1:9-9:1), container size (35-125 mL), and charging rate (20-50%) in the container were also investigated under the operational conditions of 500 rpm and 50 s. At a 20% charging rate in a 35 mL container, the blending precision of the mixtures was not influenced by the blending ratio, and was less than 6.08%, indicating homogeneity. With an increase in the charging rate, however, the blending precision decreased. The possible amount of both mixtures rose to about 17 g with a 20% charging rate in a 125 mL container. Furthermore, weight loss of medicines with this method was smaller than that with the pestle and mortar method, suggesting that this method is safer for pharmacists. In conclusion, we have established a precise and safe method for blending powdered medicines in pharmacies.

A Comparative Study of Engine Performance and Exhaust Emissions Characteristics of Linseed Oil Biodiesel Blends with Diesel Fuel in a Direct Injection Diesel Engine

Science.gov (United States)

Salvi, B. L.; Jindal, S.

2013-01-01

This paper is aimed at study of the performance and emissions characteristics of direct injection diesel engine fueled with linseed oil biodiesel blends and diesel fuel. The comparison was done with base fuel as diesel and linseed oil biodiesel blends. The experiments were conducted with various blends of linseed biodiesel at different engine loads. It was found that comparable mass fraction burnt, better rate of pressure rise and BMEP, improved indicated thermal efficiency (8-11 %) and lower specific fuel consumption (3.5-6 %) were obtained with LB10 blend at full load. The emissions of CO, un-burnt hydrocarbon and smoke were less as compared to base fuel, but with slight increase in the emission of NOx. Since, linseed biodiesel is renewable in nature, so practically negligible CO2 is added to the environment. The linseed biodiesel can be one of the renewable alternative fuels for transportation vehicles and blend LB10 is preferable for better efficiency.

Full Text Available In order to meet the energy requirements, there has been growing interest in alternative fuels like biodiesels, ethyl alcohol, biogas, hydrogen and producer gas to provide a suitable diesel substitute for internal combustion engines. An experimental investigation was performed to study the performance, emissions and combustion characteristics of diesel engine fuelled with blends of Jatropha methyl ester and diesel. In the present work three different fuel blends of Jatropha methyl ester (B10, B20, B40 and B100 were used. The increments in load on the engine increase the brake thermal efficiency, exhaust gas temperature and lowered the brake specific fuel consumption. The biodiesel blends produce lower carbon monoxide & unburned hydrocarbon emission and higher carbon dioxide & oxides of nitrogen than neat diesel fuel. From the results it was observed that the ignition delays decreased with increase in concentration of biodiesel in biodiesel blends with diesel. The combustion characteristics of single-fuel for biodiesel and diesel have similar combustion pressure and HRR patterns at different engine loads but it was observed that the peak cylinder pressure and heat release rate were lower for biodiesel blends compared to those of diesel fuel combustion.

2018-05-01

Full Text Available The main objective of this paper isto highlight the dynamics, diversity and especially the availability of an alternative financial market, developed outside of the traditional banking system, on online trading platforms, a market that can constitute an efficient solution, at the expense of entities open to fast funding, wide raging, with limited guaranties and minimum procedural and legislative formalities. For this purpose, we shall analyze briefly the main alternative financing methods, both empirically and qualitatively, in terms of similarities and differences between the two of them, inclusively of the amount that can be employed in this process through different methods. The current paper aims to be a practical guide meant to support those facing difficulties in obtaining financing for start-ups, implementing or/and developing business and entrepreneurship initiatives, and also a guide for those who want to be informed regarding the latest funding techniques. Another aspect to be considered is the legal framework in which this process takes place, because the regulation for these levers remains constantly behind the development process of new methods. The classic financiers should also consider reviewing the lending policy as the amounts attracted and accessed through these alternative methods increase exponentially from one year to the other, the volume of sums involved surpassing each time the forecasts, making thus possible the transformations of these paradigms from the financial sector into preponderant financial funding’s.

In this work silk fibroin/pullulan blend films have been prepared by solution casting method. The blend films were examined for structural, and thermal properties using X-ray diffraction (XRD), thermogravimatric (TGA) and differential scanning calorimetry (DSC) analysis. The XRD results indicate that with the introduction of pullulan, the interaction between SF and pullulan in the blend films induced the conformation transition of SF films and amorphous phase increases with increasing pullulan ratio. The thermal properties of the blend films were improved significantly in the blend films.

Correspondence Theory and Phonological Blending in French

Directory of Open Access Journals (Sweden)

Lee Scott

2014-07-01

Full Text Available Though less productive than rival word-formation processes like compounding and affixation, blending is still a rich source of neologisms in French. Despite this productivity, however, blends are often seen by scholars as unpredictable, uninteresting, or both. This analysis picks up where recent studies of blending have left off, using Correspondence Theory and a bundle of segmental constraints to deal with this phenomenon as it pertains to French. More specifically, it shows that blending is the result of a single output standing in correspondence with two or more other outputs, and that we do not need to refer to prosodic information, which is crucial in accounts of blending in languages with lexical stress like English, to account for the process in French. The analysis also differs from previous studies in that it locates blending exclusively within the phonology, leaving its morphological and semantic characteristics to be handled by other processes in the grammar.

Blended working: for whom it may (not work.

Full Text Available Similarly to related developments such as blended learning and blended care, blended working is a pervasive and booming trend in modern societies. Blended working combines on-site and off-site working in an optimal way to improve workers' and organizations' outcomes. In this paper, we examine the degree to which workers feel that the two defining features of blended working (i.e., time-independent working and location-independent working enhance their own functioning in their jobs. Blended working, enabled through the continuing advance and improvement of high-tech ICT software, devices, and infrastructure, may be considered beneficial for workers' perceived effectiveness because it increases their job autonomy. However, because blended working may have downsides as well, it is important to know for whom blended working may (not work. As hypothesized, in a sample of 348 workers (51.7% women, representing a wide range of occupations and organizations, we found that the perceived personal effectiveness of blended working was contingent upon workers' psychological need strength. Specifically, the perceived effectiveness of both time-independent working and location-independent working was positively related to individuals' need for autonomy at work, and negatively related to their need for relatedness and need for structure at work.

ZnSe nanowires with a dominant wurtzite structure have been grown at low temperature (300 °C) by molecular beam epitaxy assisted by solid Au nanoparticles. The nanowires emission is polarized perpendicularly to their axis in agreement with the wurtzite selection rules. Alternations of wurtzite and zinc-blende regions have been observed by transmission electron microscopy, and their impact on the nanowires optical properties has been studied by microphotoluminescence. The nanowires show a dominant intense near-band-edge emission as well as the ZnSe wurtzite free exciton line. A type II band alignment between zinc-blende and wurtzite ZnSe is evidenced by time-resolved photoluminescence. From this measurement, we deduce values for the conduction and valence band offsets of 98 and 50 meV, respectively.

2015-01-01

Highlights: • A compound combustion concept was proposed and investigated. • Premixed combustion near the top dead center was investigated using blended fuels. • Increasing gasoline blend ratio was found to enhance the mixture preparation. • Too much addition of gasoline decreases indicated thermal efficiency. • Gasoline/diesel blends may be a promising alternative for premixed combustion. - Abstract: The effects of gasoline/diesel blended fuel composed of diesel fuel with gasoline as additives in volume basis, on combustion, fuel economies and exhaust emissions were experimentally investigated. Tests were carried out based on a turbocharged Common-rail Direct Injection engine at a constant engine speed of 1800 r/min and different loads of 3.2 bar, 5.1 bar Indicated Mean Effective Pressure. Additionally, the effect of combustion phasing and Exhaust Gas Recirculation were evaluated experimentally for various fuels. The results indicated that with the fraction of gasoline increasing in blends, the ignition delay was prolonged and the combustion phasing was retarded with the common injection timing. This led to a significant increase of premixed burning phase, which was in favor of smoke reduction; although, too much gasoline might be adverse to fuel consumption. An optimum combustion phasing was identified, leading to a higher thermal efficiency and better premixed combustion with blended fuels. A combined application of Exhaust Gas Recirculation and blended fuel with a high gasoline fraction was confirmed effective in reducing the oxides of nitrogen and smoke emissions simultaneously at the optimum combustion phasing without giving significant penalty of fuel consumption. A compound combustion mode with its emission lower than the conventional Compression Ignition engines, and efficiency higher than the typical Spark Ignition engines, could be achieved with a cooperative control of Exhaust Gas Recirculation and combustion phasing of the gasoline

Independent power project finance rating criteria

Continuing growth of project financing for non-utility generators in the US and abroad has led to growing focus on their credit strength. In general, the financings remain relatively risky and would likely be rated below investment grade, because of various factors: loose power purchase arrangements, poor match between power pricing and fuel costs, aggressive leverage, troubled operating performance. But S and P believes some projects have the credit strength to support investment grade ratings. As traditional financing markets for these projects --- bank lending and private placements with highly specialized institutional investors --- have contracted, project sponsors and developers are considering broader markets. These include institutional investors without specialized focus on power project finance. In these markets, distinctions among projects may lead to greater liquidity and efficiency in developing the pricing and terms under which projects can be financed. This paper reports that ratings are most appropriate for projects seeking permanent financing as they enter commercial operations. They also may be useful for projects which have been operating for some time and for some very strong projects which are raising construction financing. To guide both project developers and investors in project financing, S and P has developed the following approach for rating these types of financings

2012-07-01

Continuous effort to reducing pollutant emissions, especially smoke and nitrogen oxides from internal combustion engines, have promoted research for alternative fuels. Vegetable oils, because of their agricultural origin and due to less carbon content compared to mineral diesel are producing less CO2 emissions to the atmosphere. It also reduces import of petroleum products. In the present contribution, experiments were conducted using Jatropha oil blends with diesel to study the effect on performance and emissions characteristics of a existing diesel engine. In this study viscosity of Jatropha oil was reduced by blending with diesel. A single cylinder, four stroke, constant speed, water cooled, diesel engine was used. The results show that for lower blend concentrations various parameters such as thermal efficiency, brake specific fuel consumption, smoke opacity, CO2, and NO x emissions are acceptable compared to that of mineral diesel. But, it was observed that for higher blend concentrations, performance and emissions were much inferior compared to diesel.

Nylon 6 is a widely used engineering polymer, and has relatively poor impact strength. Ethylene, n-Butyl acrylate, maleic anhydride (E-nBA-MAH) terpolymer is blended with Nylon 6 to enhance its impact strength. Mixture should be compatible to be used in applications. The bare interaction energy between Nylon 6 and E-nBA-MAH terpolymer is calculated according to melting point depression approach using both Flory-Huggins (FH) Theory and Sanchez-Lacombe Equation of State (SL EOS). It demonstrates that blends are thermodynamically favorable to any arrangements. Yet, isothermal crystallization kinetics and WAXS crystallization peaks of blends reveal that mixtures of various compositions have different crystallization behaviors and require alternating crystallization energy due to crystalline structures of individual polymers. Also, SEM images support that after 5% addition of elastomeric terpolymer, interaction loosens due to strong crystalline structure of Nylon 6.

Rowley, D.A.

1991-01-01

This paper will first explore new EPA regulations and how they are driving demand for environmental facilities. Special attention will be paid to the legal interaction of technology and federal and state policymaking. Attention also will be paid to the barriers to capital formation caused by federal regulation and the legal inadequacy of many infrastructure systems at the state and local level. Next, the paper will consider the implication of various financing techniques in light of these regulatory developments. Particular attention will be paid to existing legal and structural difficulties to the use of each of these three approaches, including tax incentives at the federal level, inability to use pollution control financing mechanisms in states, and the general decline of the availability of industrial revenue bond mechanisms. Finally, the paper will explore alternate credit support techniques that might be used to fill gaps between the regulatory pressures and the possible finance structures. It will examine possible uses of letters of credit, guarantees, forms of equity investment. Other, more difficult credit support devices such as insurance will be given brief consideration. Finally, there will be a brief overview of the liability implication for the various participants (debt inequity) in the financing of these facilities

2014-07-01

Highlights: • The effects of gamma irradiation on SiR-EPDM blend are examined. • Cross-linking reaction is dominant in blends C, D and E, due to higher EPDM content. • The tensile strength and hardness of blend E is improved by gamma irradiation. • The blend C and EPDM rich blends (D, E) are found to have superior performance. • Among C, D and E, suitable blend can be selected for a particular NPP application. - Abstract: Cable insulation materials (CIM) should perform their safety functions throughout their installed life in nuclear power plants (NPP). The CIM will be exposed to gamma irradiation at the installed locations. In order to forecast long-term performance of CIM, the short time accelerated testing was carried out. Due to its good mechanical strength, ethylene propylene diene monomer (EPDM) is widely used as CIM. Silicone rubber (SiR) is used in high temperature environments, due to its good di-electric properties/hydrophobicity. The blending of these two polymers may result in the improvement in their specific properties. This paper analyses the effects of gamma irradiation on the five different compositions (90-10; 70-30; 50-50; 30-70; 10-90) of SiR-EPDM blends. The blends were exposed to four different doses (25 Mrad, 100 Mrad, 200 Mrad and 250 Mrad) of gamma irradiation. The electrical and mechanical parameters like volume resistivity (VRY), surface resistivity (SRY), tensile strength (TS), elongation at break (EB), hardness (H) of the virgin and gamma irradiated blends were determined as per ASTM/IEC standards. The nature of degradation was investigated using Fourier transform infrared spectroscopy (FTIR). The simultaneous occurrence of cross-linking and chain scission is found to be the mechanism for ageing in SiR-EPDM blends. The electrical parameters such as volume resistivity and surface resistivity of all the blends are found to improve for all doses of gamma irradiation. To validate the influence of cross-linking reaction of the Si

Referring to the national energy policy targets for the years 2025, the government has launched the use of coal briquettes as an alternative energy replacement for kerosene and firewood. Non-carbonized briquettes in the form of coal briquettes as well as bio-coal briquettes are used in many small-medium industries and households, and are rarely used by large industries. The standard quality of coal briquettes used as raw material for non-carbonized briquettes is a minimum calorific value of 4,400 kcal/kg (adb); total sulfur at a maximum of 1% (adb), and water content at plants), the environment of deposition, and the geological conditions of the surrounding area, so that the coal deposits in each region will be different as well as the amount and also the quality. Therefore, the quantity and the quality of coal in each area are different to be eligible in the making of briquettes to do blending. In addition to the coal blending, it is also necessary to select the right materials in the making of coal briquettes and bio-coal briquettes. The formulation of the right mixture of material in the making of briquettes, can be produced of good quality and environmental friendly.

Full Text Available Financial systems and companies have become the most important reasons in the weakness of world economic system. The formation and development process of the financial structure also constitute the infrastructure of the world economic system. The path of the financial system and development has led to discuss with the financial crisis in 2008-2011. One of the solutions in order to reduce problems caused by the conventional banking system is alternative financing systems. In Turkey, the corporations based on profit share system are named participation banks. These banks which settle on different principles in the risk distribution of the portfolio acquired are analyzed more nowadays. Participation based banks are placed in practically every regulation related to banking terms and get their legal infrastructure more steady in the banking legislation of Turkey. This study is a continuation of a series related to the situation of participation banking in Turkey. On the other hand, the literature and the history of participation banking have been given less attention in this study. Literature information on methods in participation banks has been described in previous work of the series. Two analyzes were conducted in this study. One analysis is interpretive analysis that expresses the situation of applications of participation banking against banking risks. The other is an analysis of the figures of participation banks in Turkey as a continuation of the series. This study is a 2007-2015 part of research series. The study tries to explore the place and the importance of participation based banking with the various sub-headings, especially in Turkey. For this reason, we examine the comparative review 2007-2015 data of participation banks which are composed of Total Assets, Equity Net Profit, Collected Funds and Bank Loan Funds. Then we compare the total figures with deposit banks for the same period in Turkey.
