While chemical reactions may be used inside the transmitter nodes, receiver nodes or the communication medium, we focus on its utility in the medium in this paper. Such chemical reactions can be used to perform computation over the medium as molecules diffuse and react with each other (physical-layer computation). We propose the use of chemical reactions for...

Challenges and Considerations for Innovative Small and Medium Sized Reactors

There is an ongoing interest in Member States in the development and application of small and medium sized reactors (SMRs). In the near term, most new NPPs are likely to be evolutionary water cooled reactor designs building on proven systems while incorporating technological advances and often the economics of scale, resulting from the reactor outputs of up to 1600 MW(e). For a longer term, the focus is on innovative designs aiming to provide increased benefits in the areas of safety and security, non-proliferation, waste management, resource utilization and economy, as well as to offer a variety of energy products and flexibility in design, siting and fuel cycle options. Many innovative designs are reactors within the SMR range, having an equivalent electric power less than 700 MW(e) or even less than 300 MW(e). It is important that small or medium sized reactor does not necessarily mean small or medium sized nuclear power plant. The majority of innovative SMR concepts and designs provide for power station configurations with several units at a site or for NPP configurations with 2 or more reactor modules. In most cases, the units or modules could be added incrementally. Innovative SMRs are in many cases intended for markets different from those in which large nuclear power plants operate, i.e., markets that value more distributed electrical supplies, a better match between supply increments and investment capability or demand growth, more flexible siting or greater product variety. SMRs cannot compete with larger capacity plants on an economy of scale basis. However, they could be competitive via employing alternative design strategies, taking advantage of smaller reactor size resulting in a less complex design and operation and maintenance or in an increased overall energy conversion efficiency, and by relying on alternative deployment strategies, taking advantage of multiple unit factors and learning curve, and shorter construction schedule and 'exact' unit

Full Text Available The ability to introduce various concepts and business models is nowadays a prerequisite of creating a competitive advantage. This is to a large extent closely linked to the ability of enterprises to create, implement and disseminate a variety of innovative solutions. Today the use of open innovation is a necessity. This applies not only to large organisations, but also to small and medium-sized enterprises. In order to implement open innovation, small and medium-sized enterprises need to effectively manage their own growth through the preparation of appropriate strategies and the development of a model that encompasses all changes, taking into account a number of factors related to the growth dynamics of this sector. It is understood that an appropriate organisational culture plays an important role in the implementation of innovation in the sector of small and medium-sized enterprises. There are many indications that a cultural mismatch and misunderstanding are the main reasons for major problems related to the low level of implementation of innovation by small and medium-sized enterprises. The aim of the paper is to outline the issue of the impact of organisational culture on the development of the concept of open innovation in the sector of small and medium-sized enterprises.

2011-12-01

Full Text Available Small and Medium-sized Enterprises (SME in general and particularly innovative ones are becoming an increasingly important factor on the road to achieving smart, sustainable and comprehensive development. Because of their propensity to innovative undertaking and risk, SMEs contribute significantly to economic growth but are generally less productive and pay the cost of high rates of death and lower rates of profitability. Financing SMEs is risky and uncertain and for innovative SMEs it is even more difficult to access financing. When financing innovative activities, investors perceive high risks and it is even more emphasized in times of crisis when there is an increase in the cost of capital. Institutional support and governmental programmes have an important role in closing financial gap that innovative SMEs are faced with. Because the survival and development of SMEs is to a great extant determined by their ability to access favorable financing, the main objective of this paper is to provide policy recommendations for promoting availability of financing to innovative SMEs in order to foster economic recovery and more dynamic development of Serbia. The recommendations are to emerge from analyzes and evaluation of currently available sources of finance for innovative SMEs.

2016-09-01

Full Text Available Long-established Schumpeterian theory on innovation assumes that significant innovations are generated by large companies with ample spare resources. The allocation of time and money to speculative endeavours with unclear outcomes has often been regarded as beyond the scope of small and medium-sized enterprises (SMEs. As a result, authorities sometimes advise SMEs to concentrate on the adoption of existing innovative products and processes rather than the generation of new creative ideas. Despite this traditional wisdom, some very capable individuals actively choose to participate in the SME sector because the relative absence of internal bureaucratic processes and the capacity for agile response to changing circumstances. Ten case studies of significant technical innovations generated within construction SMEs were examined in the light of common themes identified through a literature review. The case studies were classified according to existing taxonomies of innovation. Content analysis was used to map the identified themes against the published material about the innovations from patent applications, company websites, trade literature and industry magazines. The findings indicate that SME innovation stems from several distinct motivations. These drivers of innovation can be described vectors. They inspire innovative solutions but the generated innovations also drive development towards solutions for other, quite different problems.

2017-07-01

Objectives: This research evaluates how the effectiveness of the small- and medium-sized enterprises’ (SMEs knowledge management systems enhance new value innovations so as to identify the major paradoxes and a business model that coherently integrates knowledge management with new value innovations. Method: Using a qualitative research method, semi-structured interviews were used to explore the opinions of 20 purposively sampled managers from 20 SMEs on how knowledge management edifies new value innovations. Results: A strong culture of information utilisation was found to enhance relevant analysis and identification of new gaps in the markets that must be filled through new value innovations or modifications of the existing products. However, poor culture of knowledge utilisation, cost of knowledge management and the often poorly functional business information systems were still reiterated as major paradoxes hampering effective knowledge management as one of the determinants of new value innovations. Conclusion: The study concluded with a model highlighting a continuum of knowledge management–new value innovation pillars like a strong culture of information utilisation, and encouragement of creativity that the executives must consider to create an effective knowledge management foundation that subsequently leverages the overall effectiveness of new value innovations.

1977-12-01

Recent plasma engineering studies have ascertained a viable concept for The Next Step (TNS) reactor based on medium toroidal fields between 4 T and 7 T at the plasma center, plasma anti β values up to 10%, and averaged densities between 0.6 x 10 14 cm -3 and 2.5 x 10 14 cm -3 . Plasma engineering innovations that can substantially reduce the size, cost, and complexity of the TNS reactor have been explored and are summarized. It is shown that the previously anticipated requirement of high pellet velocities can be substantially reduced; the toroidal field (TF) ripple requirements may be relaxed to reduce the number of TF coils and improve machine access; hybrid equilibrium field (EF) coils have been shown to require building only small interior coils and to reduce the power supply required by the exterior coils; proper approaches of microwave plasma preheating may reduce the peak loop voltage for start-up by an order of magnitude. The medium-field TNS reactor concepts and the plasma engineering innovations discussed should be applicable to other designs of tokamak reactors; some of the suggested innovations will be tested in upcoming experiments

Organizational Culture and Open Innovation Performance in Small and Medium-sized Enterprises (SMEs in Poland

Directory of Open Access Journals (Sweden)

Mazur Jolanta

2016-09-01

Full Text Available This study investigates the links between organizational culture, the use of open innovation sources and the performance of SMEs. The main hypothesis of the study is that a special type of organizational culture (termed innovative culture, which fosters creativity, learning and inter-employee cooperation – will correspond with a greater scope of open innovation sources and higher levels of innovative, operational and financial performance. The study was based on a representative CATI survey of 473 SMEs operating in manufacturing and services industries in Poland. Our statistical analysis relied on building and testing structural equation model with the AMOS software. The findings confirmed a positive association between innovative culture and the scope of open sources of innovation. However, innovative culture had no direct effect on the percentage of sales from new and modified products, which is often used as a metric of innovativeness, but did show a positive influence on an index of operational performance and ROI. Such statistical patterns suggest that fostering innovative culture is beneficial to a company, though probably not through an increased number of product innovations, but rather via process, administrative and marketing innovations, as well as other gains in efficiency attained due to more streamlined employee cooperation and knowledge exchange. The study adds to the existing body of knowledge in management science by providing a better understanding of mechanisms underlying innovative culture’s impacts on open innovation practices and metrics of operational and financial performance in the context of small and medium enterprises.

Multiple scattering in the nuclear rearrangement reactions at medium energy

International Nuclear Information System (INIS)

Tekou, A.

1980-09-01

It is shown that the multiple scattering mechanism is very important in the transfer of the large momenta involved in the nuclear rearrangement reactions at medium energy. In contrast to the usual belief, the reaction cross-section is not very sensitive to the high momenta components of the nuclear wave function. The multiple scattering mechanism is especially important in 4 He(p,d) 3 He reaction around 800 MeV. Here the collisions involving two nucleons of the target nucleus are dominant. The triple collisions contribution is also important. The four collision contribution is negligible in the forward direction and sizeable at large angles. Thus, using the K.M.T. approach in DWBA calculations, the second order term of the optical potential must be included. So, is it not well established that the second term of the K.M.T. optical potential is important for the proton elastic scattering on light nuclei. (author)

First, we report a theoretical estimation of the reaction enthalpies for the proposed processes.

In particular, the more exothermic processes correspond to the reactions of ionized and protonated hydroxylamine with formaldehyde. In addition, a neutral-neutral reaction has also been considered.

Full Text Available Abstract Background There is a growing recognition of the importance of introducing new ways of working into the UK's National Health Service (NHS and other health systems, in order to ensure that patient care is provided as effectively and efficiently as possible. Researchers have examined the challenges of introducing new ways of working--'organisational innovations'--into complex organisations such as the NHS, and this has given rise to a much better understanding of how this takes place--and why seemingly good ideas do not always result in changes in practice. However, there has been less research on the medium- and longer-term outcomes for organisational innovations and on the question of how new ways of working, introduced by frontline clinicians and managers, are sustained and become established in day-to-day practice. Clearly, this question of sustainability is crucial if the gains in patient care that derive from organisational innovations are to be maintained, rather than lost to what the NHS Institute has called the 'improvement-evaporation effect'. Methods The study will involve research in four case-study sites around England, each of which was successful in sustaining its new model of service provision beyond an initial period of pilot funding for new genetics services provided by the Department of Health. Building on findings relating to the introduction and sustainability of these services already gained from an earlier study, the research will use qualitative methods--in-depth interviews, observation of key meetings, and analysis of relevant documents--to understand the longer-term challenges involved in each case and how these were surmounted. The research will provide lessons for those seeking to sustain their own organisational innovations in wide-ranging clinical areas and for those designing the systems and organisations that make up the NHS, to make them more receptive contexts for the sustainment of innovation.

CSP technologies can be applied for distributed energy production, on small-medium plants (on the 1 MW scale), to satisfy the needs of local communities, buildings and districts. In this perspective, reliable, low-cost, and flexible small/medium multi-generative CSP plants should be developed. Four pilot plants have been built in four Mediterranean countries (Cyprus, Egypt, Jordan, and Italy) to demonstrate the approach. In this paper, the plant built in Italy is presented, with specific innovations applied in the linear Fresnel collector design and the Thermal Energy Storage (TES) system, based on a single the use of molten salts but specifically tailored for small scale plants.

Designing and Validating a Model for Measuring Sustainability of Overall Innovation Capability of Small and Medium-Sized Enterprises

Full Text Available The business environment is currently characterized by intensified competition at both the national and firm levels. Many studies have shown that innovation positively affect firms in enhancing their competitiveness. Innovation is a dynamic process that requires a continuous, evolving, and mastered management. Evaluating the sustainability of overall innovation capability of a business is a major means of determining how well this firm effectively and efficiently manages its innovation process. A psychometrically valid scale of evaluating the sustainability of overall innovation capability of a firm is still insufficient in the current innovation literature. Thus, this study developed a reliable and valid scale of measuring the sustainability of overall innovation capability construct. The unidimensionality, reliability, and several validity components of the developed scale were tested using the data collected from 175 small and medium-sized enterprises in Iran. A series of systematic statistical analyses were performed. Results of the reliability measures, exploratory and confirmatory factor analyses, and several components of validity tests strongly supported an eight-dimensional (8D scale of measuring the sustainability of overall innovation capability construct. The dimensions of the scale were strategic management, supportive culture and structure, resource allocation, communication and networking, knowledge and technology management, idea management, project development, and commercialization capabilities.

Status of innovative small and medium sized reactor designs 2005. Reactors with conventional refuelling schemes

International Nuclear Information System (INIS)

2006-03-01

There is a renewed interest in Member States in the development and application of small and medium sized reactors (SMRs). In the near term, most new NPPs are likely to be evolutionary designs building on proven systems while incorporating technological advances and often the economics of scale, resulting from the reactor outputs of up to 1600 MW(e). For the longer term, the focus is on innovative designs aiming to provide increased benefits in the areas of safety and security, non-proliferation, waste management, resource utilization and economy, as well as to offer a variety of energy products and flexibility in design, siting and fuel cycle options. Many innovative designs are reactors within the small-to-medium size range, having an equivalent electric power less than 700 MW(e) or even less than 300 MW(e). The projected timelines of readiness for deployment are generally between 2010 and 2030. The objective of this report is to provide Member States, including those just considering the initiation of nuclear power programmes, and those already having practical experience in nuclear power, with a balanced and objective information on important development trends and objectives of innovative SMRs for a variety of uses, on the achieved state-of-the-art in design and technology development for such reactors and on their design and regulatory status. The report is intended for many categories of stakeholders, including regulators, electricity producers, designers, non-electrical producers and policy makers. The main chapters of this report, addressed to all abovementioned groups of stakeholders, provide a summary of major specifications, applications and user-related special features of innovative SMRs, outline the achieved design and regulatory status and its progress since previous IAEA publications, review targeted deployment dates, fuel cycle options, design approaches used to meet design objectives in specific subject areas, enabling technologies and current

Strategies for innovation in multicomponent reaction design.

By generating structural complexity in a single step from three or more reactants, multicomponent reactions (MCRs) make it possible to synthesize target compounds with greater efficiency and atom economy. The history of such reactions can be traced to the mid-19th century when Strecker first produced alpha-aminonitriles from the condensation of aldehydes with ammonia and hydrogen cyanide. Recently, academic chemists have renewed their interest in MCRs. In part, the pharmaceutical industry has fueled this resurgence because of the growing need to assemble libraries of structurally complex substances for evaluation as lead compounds in drug discovery and development programs. The application of MCRs to that increasingly important objective remains limited by the relatively small number of such reactions that can be broadly applied to prepare biologically relevant or natural-product-like molecular frameworks. We were interested in applying logic-based approaches, such as our single reactant replacement (SRR) approach, as a way both to improve known MCRs and to design new multiple-component routes to bioactive structures. This Account provides several examples that illustrate the use of SRR with known MCRs as starting points for synthetic innovation in this area. As part of our working hypothesis, we initially explored strategies for engineering improvements into known MCRs, either by increasing the dimensionality--that is, changing an n-component to an (n + 1)-component reaction--or broadening the scope of useful input structures, or both. By exhaustively applying retrosynthetic analysis to the cognate MCR to identify and exploit alternative entry points into the overall reaction manifold, we have devised several such re-engineered MCRs. Serendipitous findings have also augmented the yield of useful developments from our logic-inspired approach. In some cases, we have identified surprising links between different compound families that provide useful new entry points

The intramolecular Diels-Alder reaction has been used as a powerful method to access the tricyclic core of the eunicellin natural products from a number of 9-membered-ring precursors. The endo/exo selectivity of this reaction can be controlled through a remarkable organocatalytic approach, employing MacMillan's imidazolidinone catalysts, although the mechanistic origin of this selectivity remains unclear. We present a combined experimental and density functional theory investigation, providing insight into the effects of medium-ring constraints on the organocatalyzed intramolecular Diels-Alder reaction to form the isobenzofuran core of the eunicellins.

The aim of this prospective study was to evaluate and compare acute adverse reactions between contrast medium containing moderate and high concentrations of iodine in patients undergoing computed tomography (CT). A total of 945 patients undergoing enhanced CT were randomly assigned to receive one of two doses of contrast medium. We then prospectively investigated the incidence of adverse reactions. Iopamidol was used as the contrast medium, with a high concentration of 370 mgI/ml and a moderate concentration of 300 mgI/ml. The frequency of adverse reactions, such as pain at the injection site and heat sensation, were determined. Acute adverse reactions were observed in 2.4% (11/458) of the moderate-concentration group compared to 3.11% (15/482) of the high-concentration group; there was no significant difference in incidence between the two groups. Most adverse reactions were mild, and there was no significant difference in severity. One patient in the high-concentration group was seen to have a moderate adverse reaction. No correlation existed between the incidence of adverse reactions and patient characteristics such as sex, age, weight, flow amount, and flow rate. The incidence of pain was not significantly different between the two groups. In contrast, the incidence of heat sensation was significantly higher in the high-concentration group. The incidence and severity of acute adverse reactions were not significantly different between the two groups, and there were no severe adverse reactions in either group. (author)

Full Text Available Objective of this article is to determine possible effect of product innovations on the financial performance of small and medium-sized enterprises in the Czech Republic. The pilot research has been realized on the statistical sample of 100 companies which were categorized into three basic groups; service companies, trade companies, and production companies. As the measure of innovation effect, the authors applied the deviation of production power, i.e. the ration of EBIT to assets, of a business entity from the industry average while the industry average of production power was selected especially in order to reduce the influence of the economy cycles. In the three categories of companies, different effects of product innovations have been observed. In the service companies and trade companies, the positive effect is limited because of potential simplicity of imitation by competitors. More positive effect of product innovations has been observed in production companies which can protect the products or production processes better then service companies or trade companies where the product innovations are mostly connected with extension of extension of services portfolio offered. For the conclusion, the authors provide suppositions and designs for their future research in this problem of innovations’ effectiveness measurement.

Influence of the medium on the reaction rate of the t-butoxyl radical with iron(II)

International Nuclear Information System (INIS)

Mihaljevic, B.; Razem, D.

2002-01-01

Complete text of publication follows. Tert-butoxyl radicals (t-BuO.) were generated by homolytic photodecomposition of di-tert-butylperoxide using ruby laser flashes at 347 nm. The reaction of t-BuO. radicals with Fe 2+ was studied under pseudo-first order conditions. The quantum yield Φ(Fe 3+ ) was determined by measuring the absorbance of Fe 3+ ion as [FeCl] 2+ complex at 360 nm 2 μs after the flash. According to the equation derived from the reaction scheme, the rate constant k 3 was obtained from the relative rate constant k r (k r =k 0 /k 3 ) and the value of k 0 ; the latter refers to the overall rate of the competing disappearance of t-BuO. radicals from the system (reaction 2), including the highest contribution of β-cleavage. The rate constant k 0 was determined using diphenylmethanol instead of Fe 2+ . The known rate constant of the reaction of t-BuO. radical with diphenylmethanol giving ketyl radicals (6.9 x 10 6 dm 3 mol -1 s -1 ) was applied. The quantum yield of ketyl radicals was determined by measuring the maximum of absorbance at 535 nm. At acid concentration of 0.023 mol dm -3 HCl the rate constant k 3 = 3.4 x 10 8 dm 3 mol -1 s -1 was determined. The relative rate constant increased with an increase of the hydrochloric acid concentration which has been ascribed to the lower stability of t-BuO. radical at higher acidity of the medium. The effect of polarity of the medium on the reaction rate was also determined. Decreasing k 3 in media of increasing polarity were explained by increasing of the β-scission rate of t-BuO. radical with increasing polarity of the medium

Highlights: •Presenting a facile one–pot approach to prepare polyaniline nanofibers through simply tuning acid–base environment of reaction medium. •Determining the role of aniline oligomers play in the formation of polyaniline nanofibers. •Demonstrating the feasibility of polyaniline nanofibers as high–performance electrode materials for supercapacitors. -- Abstract: A facile and efficient one–pot approach was presented to prepare polyaniline (PANi) nanofibers through simply tuning acid–base environment of reaction medium without the assistance of templates or use of organic solvents, in which aniline oligomers formed in the alkaline solution were used as “seeds” for the oriented growth of PANi chains under acidic conditions. The as–prepared PANi nanofibers were investigated by field–emission scanning electron microscopy, ultraviolet–visible spectroscopy, Fourier transform infrared spectroscopy and X–ray diffraction technology. Furthermore, the electrochemical properties were evaluated by cyclic voltammetry, galvanostatic charge–discharge test, and electrochemical impedance spectroscopy. More attentions were paid to the influence of aniline concentrations in alkaline and acidic reaction medium on the morphology, microstructure and properties of PANi nanofibers. It can be found that aniline concentration in alkaline medium has a stronger impact on the electrical and electrochemical properties of final products, however, their morphologies obviously depend on aniline concentration in acidic solution. Moreover, PANi nanofibers prepared at aniline concentrations of 48 mM in alkaline medium and 0.2 M in acidic medium exhibits the largest specific capacitance of 857.2 F g −1 at the scan rate of 5 mV s −1 , and capacitance retention of 63.8% after 500 cycles. It is demonstrated that such one–pot approach can present a low cost and environmental friendly route to fabricate PANi nanofibers in fully aqueous solution as high�

Effects of medium-chain triacylglycerols on Maillard reaction in bread baking.

Toyosaki, Toshiyuki

2018-06-01

To investigate the relationship between the fatty acid composition of medium-chain triacylglycerols (MCTs) and the Maillard reaction induced during bread baking, a comparison with various fatty acids was conducted. Saturated fatty acids had a remarkable inhibitory effect on the amount of advanced glycation end products (AGEs) generated from the Maillard reaction in bread baking compared to unsaturated fatty acids. The amount of AGEs produced by each fatty acid (mg kg -1 ) was as follows: C18:0, 18.7; C12:0, 35.2; C16:0, 21.4; C18:0, 38.2; C18:1, 68.7; C18:2, 80.1; C20:4, 80.8; C22:4, 89.8. Saturated fatty acids were possibly involved in the Maillard reaction and, as a result, acted to inhibit it. In the case of unsaturated fatty acids, amounts of AGEs during the Maillard reaction in baking tended to increase as the degree of unsaturation increased. In other words, there was a positive correlation between the degree of unsaturation and the amount of AGEs. It was also confirmed that the air pore distribution in baked bread was closely related to AGEs. These results led us to conclude that the fatty acid composition of the added lipids also influences properties that determine the tastiness of bread. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

Convection and reaction in a diffusive boundary layer in a porous medium: nonlinear dynamics.

Science.gov (United States)

Andres, Jeanne Therese H; Cardoso, Silvana S S

2012-09-01

We study numerically the nonlinear interactions between chemical reaction and convective fingering in a diffusive boundary layer in a porous medium. The reaction enhances stability by consuming a solute that is unstably distributed in a gravitational field. We show that chemical reaction profoundly changes the dynamics of the system, by introducing a steady state, shortening the evolution time, and altering the spatial patterns of velocity and concentration of solute. In the presence of weak reaction, finger growth and merger occur effectively, driving strong convective currents in a thick layer of solute. However, as the reaction becomes stronger, finger growth is inhibited, tip-splitting is enhanced and the layer of solute becomes much thinner. Convection enhances the mass flux of solute consumed by reaction in the boundary layer but has a diminishing effect as reaction strength increases. This nonlinear behavior has striking differences to the density fingering of traveling reaction fronts, for which stronger chemical kinetics result in more effective finger merger owing to an increase in the speed of the front. In a boundary layer, a strong stabilizing effect of reaction can maintain a long-term state of convection in isolated fingers of wavelength comparable to that at onset of instability.

An investigation of the relationship between innovation and cultural diversity.

Science.gov (United States)

Kandler, Anne; Laland, Kevin N

2009-08-01

In this paper we apply reaction-diffusion models to explore the relationship between the rate of behavioural innovation and the level of cultural diversity. We investigate how both independent invention and the modification and refinement of established innovations impact on cultural dynamics and diversity. Further, we analyse these relationships in the presence of biases in cultural learning and find that the introduction of new variants typically increases cultural diversity substantially in the short term, but may decrease long-term diversity. Independent invention generally supports higher levels of cultural diversity than refinement. Repeated patterns of innovation through refinement generate characteristic oscillating trends in diversity, with increasing trends towards greater average diversity observed for medium but not low innovation rates. Conformity weakens the relationship between innovation and diversity. The level of cultural diversity, and pattern of temporal dynamics, potentially provide clues as to the underlying process, which can be used to interpret empirical data.

Indications for in-medium modifications of hadron properties are reported from photoabsorption and meson production experiments. Strong medium modifications are observed in inclusive photoabsorption experiments and theoretical models investigate the in-medium dynamics of baryon resonances and their coupling to mesons. Recent experiments study the in-medium behavior of scalar and vector mesons where theoretical models expect in-medium modifications of the meson spectral functions that might be connected to partial restoration of chiral symmetry

A ruthenium-arene-PTA (RAPTA) complex has been supported for the first time on an inorganic solid, that is, silica-coated ferrite nanoparticles. The resulting magnetic material proved to be a general, very efficient and easily reusable catalyst for three synthetically useful organic transformations; selective nitrile hydration, redox isomerization of allylic alcohols, and heteroannulation of (Z)-enynols. The use of low metal concentration, environmentally friendly water as a reaction medium, with no use at all of organic solvent during or after the reactions, and microwaves as an alternative energy source renders the synthetic processes reported herein "truly" green and sustainable.

Production of complex particles in low energy spallation and in fragmentation reactions by in-medium random clusterization

International Nuclear Information System (INIS)

Lacroix, D.; Durand, D.

2005-09-01

Rules for in-medium complex particle production in nuclear reactions are proposed. These rules have been implemented in two models to simulate nucleon-nucleus and nucleus-nucleus reactions around the Fermi energy. Our work emphasizes the effect of randomness in cluster formation, the importance of the nucleonic Fermi motion as well as the role of conservation laws. The concepts of total available phase-space and explored phase-space under constraint imposed by the reaction are clarified. The compatibility of experimental observations with a random clusterization is illustrated in a schematic scenario of a proton-nucleus collision. The role of randomness under constraint is also illustrated in the nucleus-nucleus case. (authors)

The procedure solving this system is described, the basic parameters determining the development of the chain reaction are found and its specific time intervals are determined. The initial stage of the reaction is analysed and criteria for the development of the branching chain decomposition reaction of iodide in the COIL active medium are determined. (active media)

Bilingual teaching for multilingual students? Innovative dual-medium models in Slovene-German schools in Austria

Science.gov (United States)

Purkarthofer, Judith; Mossakowski, Jan

2011-12-01

Traditional bilingual education programmes in regional linguistic minority contexts face major challenges within the recent paradigm of linguistic diversity against a background of increasing migration, mobility and trans-locality. Based on three case studies, the authors of this paper focus on how particular dual-medium models are applied in Slovene-German schools in Carinthia, Austria. They examine not only how these schools provide for a balanced bilingual teaching and learning environment, but also how they deal with their students' multilingual realities and support their identification with bi- and multilingualism. The authors regard schools as institutional sites where linguistic dispositions are subject to discursive power relations and where language policies and educational goals are negotiated by teachers, parents and students alike. Drawing on speaker-centred and ethnographic approaches in sociolinguistic research, the authors seek to document experiences of all actors involved as well as spatial and discursive practices. Through this the authors show how these dual-medium schools achieve particular profiles in multilingual education which are potentially regarded as innovative examples of best-practice and as being of interest for students and families with heterogeneous linguistic backgrounds.

Full Text Available This paper explores the issues that influence the diffusion of innovation as it relates to the adoption of e-commerce by Small and Medium Enterprises (SMEs. It seeks to identify factors facilitating and inhibiting such adoption across contexts – regional, small city and large city. This analysis is cross cultural so the impact of differing economic and cultural issues also will be identified in this research. Whilst it is generally accepted that the strategic use of information technology (IT is vital in the marketplace, the rate of such uptake between small and large businesses varies. This research seeks to identify the reasons for this variation. It is critical to understand such factors so that steps can be taken to redress inequity of uptake that might be identified. The paper endeavours to explore factors that are needed to facilitate and encourage IT adoption and so positively influence user acceptance and use of IT innovations in SMEs. Reasons for such uptake as well as strategic approach to the adoption of e-commerce, and variations regarding same also will be considered. The paper examines existing theory as it pertains to the diffusion of innovation acknowledging the perspective of regional and urban SMEs in various cultural contexts. Empirical investigation exploring this diffusion, the rate of and approach to the uptake by SMEs is planned using a case study methodology

The dissipation phenomenon in the heavy-ion reaction at incident energy near Fermi energy is studied by simulating the reactions {sup 129}Xe + {sup 129}Sn and {sup 58}Ni + {sup 58}Ni with isospin-dependent quantum molecular dynamics model (IQMD). The isotropy ratio in terms of transverse and longitudinal energies of the free protons emitted in the final states of these reactions is quantitatively analyzed to explore the in-medium correlation of the binary collisions. Comparison of the calculations with the experimental data recently released by INDRA collaboration exhibits that the ratio is very sensitive to the Pauli blocking effect in two-body collisions and Pauli exclusion principle is indispensable in the theoretical simulations for the heavy-ion reactions near the Fermi energy.

Spin observables have been measured for (p, 2p) reactions aiming at studying medium effects on NN interactions in nuclear field. Observed strong density-dependent reduction of the analyzing power is consistent with a model calculation where reduction of nucleon and meson masses are taken into account. On the other hand, calculations with g-matrices in the Shroedinger framework does not predict the reduction. The spin-transfer coefficients, which data are not reproduced by the model calculation, are found to be sensitive to reduction rate of each meson mass and have a possibility to test scaling lows in mass reductions.

Boon or burden? Next to large industrial customers and private customers, small and medium-sized commercial customers are an important customer group for power supply companies. Being too small for a separate contract they are usually grouped together with private customers in a single customer group. However, this manner of business fails to do justice to the special needs and the potential of small and medium-sized commercial customers. Qualitative market research methods can give valuable impulses in attempts to develop innovative approaches that are more appropriate to the specific needs and requirements of small and medium-sized commercial customers, as the example set by Augsburg utilities demonstrates.

Carbon-supported cubic CoSe2 catalysts for oxygen reduction reaction in alkaline medium

Highlights: ► Cubic CoSe 2 a non-precious metal electrocatalyst for oxygen reduction in KOH. ► The catalyst shows four-electron transfer pathway in overall reaction. ► Catalyst has higher methanol tolerance than commercial Pt/C catalyst. - Abstract: A Carbon-supported CoSe 2 nanocatalyst has been developed as an alternative non-precious metal electrocatalyst for oxygen reduction reaction (ORR) in alkaline medium. The catalyst was prepared via a surfactant-free route and its electrocatalytic activity for the ORR has been investigated in detail in 0.1 M KOH electrolyte at 25 °C using rotating disk electrode (RDE) and rotating ring-disk electrode (RRDE) techniques. The prepared catalyst showed promising catalytic activity towards ORR in a four-electron transfer pathway and higher tolerance to methanol compared to commercial Pt/C catalyst in 0.1 M KOH. To some extent, the increase of CoSe 2 loading on the electrode favors a faster reduction of H 2 O 2 intermediate to H 2 O.

Linear-dendritic supramolecular complexes as nanoscale reaction vessels for "green" chemistry. Diels-Alder reactions between fullerene C60 and polycyclic aromatic hydrocarbons in aqueous medium.

Science.gov (United States)

Simonyan, Arsen; Gitsov, Ivan

2008-10-21

This study describes the first Diels-Alder (DA) reaction performed in aqueous medium with highly hydrophobic compounds-fullerene (C 60) as the dienophile and anthracene (An) or tetracene (Tet) as the dienes, respectively. The reactions are performed in nanocontainers, constructed by self-assembly of linear-dendritic amphiphilic copolymers with poly(ethylene glycol), PEG or poly(ethylene oxide), PEO as the hydrophilic blocks and poly(benzyl ether) monodendrons as the hydrophobic fragments: G3PEO13k, dG3 and dG2. Comparative studies under identical conditions are carried out with an amphiphilic linear-linear copolymer, poly(styrene)1800- block-PEO2100, PSt-PEO, and the nonionic surfactant Igepal CO-720, IP720. The binding affinity of supermolecules built of these amphiphiles toward the DA reagents decreases in the following order: G3PEO13k > dG3 > PSt-PEO > dG2 > IP720. The kinetic constant of binding is evaluated for tetracene and decreases in a similar fashion: 5 x 10 (-7) M/min (G3PEO13k), through 4 x 10 (-7) M/min (PSt-PEO) down to 1.5 x 10 (-7) M/min for IP720. The mobility of substrates encapsulated in the micellar core, estimated by pyrene fluorescence decay, is 95-121 ns for the micelles of the linear-dendritic copolymers and notably higher for PSt-PEO (152 ns), revealing the much denser interior of the linear analogue. The apparent kinetic constant for the DA reaction of C 60 and Tet within the G3PEO13k supermolecule in aqueous medium is markedly higher than in organic solvent (toluene), 208 vs 1.82 M /min. With G3PEO13k the conversions reach 49% for the DA reaction between C 60 and An, and 55% for C 60 and Tet. Besides the monoadduct (26.5% yield) the reaction with An produces exclusively increasing amounts of D 2 h -symmetric antipodal bis-adduct, whose yield reaches up to 22.5% after 48 h. In addition to the environmentally friendly conditions notable advantages of the synthetic strategy described are the extended stability of the linear

In the present paper, we reported particle size kinetic studies on the conducting polyaniline (PANI) which synthesized through a chemical oxidative polymerization technique from aniline monomer. PANI was prepared using ammonium persulfate (APS) as oxidizing agent which carried out in acidic and neutral medium at various batch temperatures of respectively 20, 30 and 50 °C. From the studies, it was noticed that the complete polymerization reaction progressed within 480 minutes duration time. The pH of the solution during reaction kinetic reached values 0.8 - to 1.2 in acidic media, while in the neutral media the pH value reached values 3.8 - 4.9. The batch temperature controlled the polymerization reaction in which the reaction progressing, which followed by the temperature rise of solution above the batch temperature before settled down to the initial temperature. An increment in the batch temperature gave highest rise in the solution temperature for the two media which cannot be more than 50 °C. The final product of polymerization reaction was PANI confirmed by Fourier Transform Infra-Red (FTIR) spectrophotometer for molecule structure identification. The averages particle size of PANI which carried out in the two different media is evidently similar in the range 30 - 40 μm and insensitive to the batch temperature. However, the particle size of PANI which obtained from the polymerization reaction at a batch temperature of 50 °C under acidic condition reached ˜53.1 μm at the tip of the propagation stage which started in the first 5 minutes. The size is obviously being the largest among the batch temperatures. Whereas, under neutral condition the particle size is much larger which reached the size 135 μm at the batch temperature of 20 °C. It is concluded that the particle size formation during the polymerization reaction being one of the important parameter to determine particle growing of polymer which indicated the reaction kinetics mechanism of synthesize

Perturbation analysis of magnetohydrodynamics oscillatory flow on convective-radiative heat and mass transfer of micropolar fluid in a porous medium with chemical reaction

Directory of Open Access Journals (Sweden)

Dulal Pal

2016-03-01

Full Text Available This paper deals with the perturbation analysis of mixed convection heat and mass transfer of an oscillatory viscous electrically conducting micropolar fluid over an infinite moving permeable plate embedded in a saturated porous medium in the presence of transverse magnetic field. Analytical solutions are obtained for the governing basic equations. The effects of permeability, chemical reaction, viscous dissipation, magnetic field parameter and thermal radiation on the velocity distribution, micro-rotation, skin friction and wall couple stress coefficients are analyzed in detail. The results indicate that the effect of increasing the chemical reaction has a tendency to decrease the skin friction coefficient at the wall, while opposite trend is seen by increasing the permeability parameter of the porous medium. Also micro-rotational velocity distribution increases with an increase in the magnetic field parameter.

In-medium behaviour of vector mesons and the longitudinal and transverse response functions in (e,e'p) reactions

International Nuclear Information System (INIS)

Soyeur, M.; Brown, G.E.; Rho, M.

1991-01-01

The electromagnetic form factors of nucleons appear dominated by vector mesons at momentum transfers small than ∼ 1 GeV/c. It is therefore expected that measurements of quantities involving the electromagnetic form factors of nucleons embedded in nuclei will be sensitive to changes in vector meson properties arising from their interaction with the medium. Longitudinal and transverse response functions measured in quasi-elastic (e,e'p) reactions provide such data for two very different operators, the charge and the current densities. We show that a decrease of vector meson masses in the medium, consistent with present expectations about chiral symmetry restoration in nuclei, produces the quenching observed in the longitudinal response of light systems ( 3 He, 4 He) and part of this quenching for heavier nuclei 40 Ca where nuclear correlations are expected to generate an additional suppression of the longitudinal response. The transverse response is almost unchanged, in agreement with the data. Difficulties in extrating very quantitative information on the in-medium behaviour of vector mesons from (e,e'p) data are pointed out

Full Text Available The present work aims to report the consequences of Darcy–Forchheimer medium in flow of Cross fluid model toward a stretched surface. Flow in porous space is categorized by Darcy–Forchheimer medium. Further heat transfer characteristics are examined via thermal radiation and heat generation/absorption. Transformation procedure is used. The arising system of nonlinear ordinary differential equations is solved numerically by means of shooting method. The effects of different flow variables on velocity, temperature, concentration, skin friction, and heat transfer rate are discussed. The obtained outcomes show that velocity was enhanced with the increase in the Weissenberg number but decays with increase in the porosity parameter and Hartman number. Temperature field is boosted by thermal radiation and heat generation; however, it decays with the increase in the Prandtl number.

Innovation, adaptability, and collaboration: Keys to success for small and medium sized reactors. Cairo, 27 May 2001

2001-01-01

Small and medium sized reactors, within a power output of less than 700 MW(e), are receiving increased consideration in the effort to meet changing market requirements. Smaller plants allow a more incremental investment, which can be used to hedge against demand uncertainty. They are more suitable for standardization and prefabrication, which in turn encourages enhanced quality control and stimulates rapid development of expertise and shorter construction schedules. They provide a better match to grid capacity in developing countries. And they are more easily adapted to a broad range of industrial settings and applications, such as district heating, heavy oil recovery, or the production of hydrogen and other chemical fuels. Sea water desalination is an application for which smaller reactors hold a particular advantage. Nuclear powered desalination is a proven technology. Clearly, we live in an era in which our society faces many difficult economic, environmental and social issues associated with sustainable development and energy demand. Against that backdrop, nuclear power is a mature technology that deserves careful consideration as a contributor to solving some of these issues. The development of innovative small and medium sized reactors will play a key role in helping to match state-of-the-art technology to user needs. An exchange of information and ideas is a step towards further progress

Wende, S.; Speck, U.

1981-06-01

The paper deals with the risk associated with the application of contrast medium in CT. The risk is to be seen in intolerance reactions, such as allergic or circulatory reactions and neurotoxic side-effects. In this paper the problems of renal failure caused by the injection of contrast medium are given special attention. Furthermore an iodine-induced hyperthyreosis might result. Especially the possible disturbance of the kidney function means that contrast medium should not be applied arbitrarily and that the examination should be done only by experienced staff. Furthermore the indication for the application of contrast medium in CT should be strictly qualified.

We aimed to investigate the safety and feasibility of duplex-assisted carotid artery stenting (CAS) without administration of contrast medium for the prevention of adverse reactions. Fifteen patients (9 % of all CASs) with severe carotid stenosis (≥70 %) associated with chronic kidney disease (CKD) (stage ≥3) or allergy to contrast medium underwent duplex-assisted CAS without administration of contrast medium over 4 years. The procedural success rate and perioperative complication rates were compared between the duplex-assisted CAS (n = 15) and conventional CAS (n = 153) groups. The technical success rate was 100 % in both groups. Combined stroke or death rates during the post-procedural period did not differ significantly between the duplex-assisted CAS group (0/15, 0 %) and conventional CAS group (4/153, 2.6 %). None of the 14 patients with CKD in the duplex-assisted CAS group experienced further deterioration of renal function. The mean surface radiation dose of participants in the duplex-assisted CAS group (n = 13, 312 ± 131 mGy) was significantly lower than that of the conventional CAS group (n = 31, 1036 ± 571 mGy) (p duplex-assisted CAS group (156 ± 39.7 min) and the conventional CAS group (156 ± 37.4 min). Duplex-assisted CAS without administration of contrast medium could be an alternative option in selected patients deemed to be at high risk for renal failure from nephrotoxic contrast medium or who have an allergy to contrast medium.

Late adverse reactions to intravascular iodinated contrast media

International Nuclear Information System (INIS)

Webb, Judith A.W.; Stacul, Fulvio; Thomsen, Henrik S.; Morcos, Sameh K.

2003-01-01

Late adverse reactions to intravascular iodinated contrast media are defined as reactions occurring 1 h to 1 week after contrast medium injection. They have received increasing interest over the past decade, but their prevalence remains uncertain and their pathophysiology is not fully understood. The Contrast Media Safety Committee of the European Society of Urogenital Radiology decided to review the literature and to issue guidelines. An extensive literature search was carried out and summarized in a report. Based on the available information, simple guidelines have been drawn up. The report and guidelines were discussed at the 8th European Symposium on Urogenital Radiology in Genoa. Late adverse reactions after intravascular iodinated contrast medium include symptoms such as nausea, vomiting, headache, itching, skin rash, musculoskeletal pain, and fever. A significant proportion of these reactions is unrelated to the contrast medium; however, allergy-like skin reactions are well-documented side effects of contrast media with an incidence of approximately 2%. Late reactions appear to be commoner after non-ionic dimers. The majority of late skin reactions after contrast medium exposure are probably T-cell-mediated allergic reactions. Patients at increased risk of late skin reactions are those with a history of previous contrast medium reaction and those on interleukin-2 treatment. Most skin reactions are self-limiting and resolve within a week. Management is symptomatic and similar to the management of other drug-induced skin reactions. (orig.)

This article advances towards the reconceptualization of financial innovation. It examines the calamitous role of financial innovation in the global financial crisis, developing a non-rational theorization of finance within the social economy that factors in the role of affect. Outlining...... the foundations for such an approach, the analysis draws on Thorstein Veblen and Georges Bataille, whose work encompasses psycho-social conceptions of political-economic agency. From the more anthropological lens of Veblen and Bataille's theorizations, it is possible to move beyond instrumentalist accounts...... of financial innovation premised on pecuniary expedients and aspirations of market completion. As we argue, in a broader affective economy, contemporary financial innovation serves invidious ends, providing a means of attaining social distinction, constituting a medium for violent expenditure and bestowing...

Spallation reactions - physics and applications

International Nuclear Information System (INIS)

Kelic, A.; Ricciardi, M.; Schmidt, K-H.

2009-01-01

Spallation reactions have become an ideal tool for studying the equation of state and thermal instabilities of nuclear matter. In astrophysics, the interactions of cosmic rays with the interstellar medium have to be understood in detail for deducing their original composition and their production mechanisms. Renewed interest in spallation reactions with protons around 1 GeV came up recently with the developments of spallation neutron sources. The project of an accelerator-driven system (ADS) as a technological solution for incinerating the radioactive waste even intensified the efforts for better understanding the physics involved in the spallation process. Experiments on spallation reactions were performed for determining the production cross sections and properties of particles, fragments and heavy residues. Traditional experiments on heavy residues, performed in direct kinematics, were limited to the direct observation of long-lived radioactive nuclides and did not provide detailed information on the kinematics of the reaction. Therefore, an innovative experimental method has been developed, based on inverse kinematics, which allowed to identify all reaction residues in-flight, using the high resolution magnetic spectrometer FRS of GSL Darmstadt. It also gives direct access to the reaction kinematics. An experimental campaign has been carried out in a Europe-wide collaboration, investigating the spallation of several nuclei ranging from 56 Fe to 238 U Complementary experiments were performed with a full-acceptance detection system, yielding total fission cross sections. Recently, another detection system using the large acceptance ALADIN dipole and the LAND neutron detector was introduced to measure light particles in coincidence with the heavy residues. Another intense activity was dedicated to developing codes, which cover nuclear reactions occurring in an ADS. The first phase of the reaction is successfully described by a sequence of quasi-free nucleon

Reactions of substituted benzene anions with N and O atoms: Chemistry in Titan’s upper atmosphere and the interstellar medium

The likely existence of aromatic anions in many important extraterrestrial environments, from the atmosphere of Titan to the interstellar medium (ISM), is attracting increasing attention. Nitrogen and oxygen atoms are also widely observed in the ISM and in the ionospheres of planets and moons. In the current work, we extend previous studies to explore the reactivity of prototypical aromatic anions (deprotonated toluene, aniline, and phenol) with N and O atoms both experimentally and computationally. The benzyl and anilinide anions both exhibit slow associative electron detachment (AED) processes with N atom, and moderate reactivity with O atom in which AED dominates but ionic products are also formed. The reactivity of phenoxide is dramatically different; there is no measurable reaction with N atom, and the moderate reactivity with O atom produces almost exclusively ionic products. The reaction mechanisms are studied theoretically by employing density functional theory calculations, and spin conversion is found to be critical for understanding some product distributions. This work provides insight into the rich gas-phase chemistry of aromatic ion-atom reactions and their relevance to ionospheric and interstellar chemistry.

Full Text Available Considering the dynamic environment, competitiveness of small and medium enterprises depends on the speed with which new products can be presented in the market. Innovation represent specific instrument of entrepreneurship, and in general entrepreneurs are bringing innovation. Innovation represents activity that impregnates the existing resources with new capacities for creation of resources. Innovation sometimes may result in brand new, unknown product or replacement of some existing function for it’s more efficient and successful performance. SMEs are more innovative than larger firms, due to their flexibility and their ability to quickly and efficiently integrate inventions created by the firms’ development activities. Hence, in this paper the main focus will be on SMEs in Macedonia, their innovation and the business environment, excually the influence of business environment for creating innovation. To prove this we will test three hypotheses by using the ANNOVA model and in the end of the paper based on the obtained results we will purpose a measures for improving the business environment in Macedonia in order to stimulate SMEs innovation.

Full Text Available Stimulating innovation is one of the pressing policy challenges facing many countries in the world today. The paper analyses the external factors that Polish entrepreneurs find most detrimental to their innovative activity. A sample of 199 small and medium size enterprises (SMEs in Poland were subjected to a survey. The data collected revealed the innovation types of SMEs in Poland and external financial factors influencing innovation the most. The results show external factors such as legal regulations, access to external financing, bureaucracy of institutions, financial government support, the tax system, time necessary to comply with regulations, and crisis and instability are very important for SMEs. According to the results, process and marketing innovations are applied more frequently than product and organisational innovations. Finally, the results indicate that entrepreneurs indicate that lack of government support and weakness of tax incentives is an important barrier to the innovation process.

There are two different ways to model reactive transport: ad hoc and innovative reaction-based approaches. The former, such as the Kd simplification of adsorption, has been widely employed by practitioners, while the latter has been mainly used in scientific communities for elucidating mechanisms of biogeochemical transport processes. It is believed that innovative mechanistic-based models could serve as protocols for environmental remediation as well. This paper reviews the development of a mechanistically coupled fluid flow, thermal transport, hydrologic transport, and reactive biogeochemical model and example-applications to environmental remediation problems. Theoretical bases are sufficiently described. Four example problems previously carried out are used to demonstrate how numerical experimentation can be used to evaluate the feasibility of different remediation approaches. The first one involved the application of a 56-species uranium tailing problem to the Melton Branch Subwatershed at Oak Ridge National Laboratory (ORNL) using the parallel version of the model. Simulations were made to demonstrate the potential mobilization of uranium and other chelating agents in the proposed waste disposal site. The second problem simulated laboratory-scale system to investigate the role of natural attenuation in potential off-site migration of uranium from uranium mill tailings after restoration. It showed inadequacy of using a single Kd even for a homogeneous medium. The third example simulated laboratory experiments involving extremely high concentrations of uranium, technetium, aluminum, nitrate, and toxic metals (e.g.,Ni, Cr, Co).The fourth example modeled microbially-mediated immobilization of uranium in an unconfined aquifer using acetate amendment in a field-scale experiment. The purposes of these modeling studies were to simulate various mechanisms of mobilization and immobilization of radioactive wastes and to illustrate how to apply reactive transport models

2011-01-01

Full Text Available The kinetics of oxidation of 3-benzoylpropionic acid (KA with N-bromoacetamide (NBA have been studied potentiometrically in 50:50 (v/v aqueous acetic acid medium at 298 K The reaction was first order each with respect to [KA], [NBA] and [H+]. The main product of the oxidation is the corresponding carboxylic acid. The rate decreases with the addition of acetamide, one of the products of the reaction. Variation in ionic strength of the reaction medium has no significant effect on the rate of oxidation. But the rate of the reaction is enhanced by lowering the dielectric constant of the reaction medium. A mechanism consistent with observed results have been proposed and the related rate law was deduced.

Assessing construction innovation: theoretical and practical perspectives

Directory of Open Access Journals (Sweden)

Peter Davis

2016-09-01

Full Text Available Innovation is key for productivity improvement and advancements in different sectors of the economy, including the construction sector.  The criticism of the slow pace of innovation in construction industry may be unwarranted, considering the structure of the industry and nature of the construction business.  The loosely coupled nature of firms, mostly Small and Medium Enterprises (SME’s, delivering ‘projects’ through partial engagement, together with the distinction between the project innovation and firm innovation makes it difficult to extract innovations in a meaningful way.  The problem also lies in conceptualising, defining, articulating and assessing innovation in construction.  The literature is replete with research into construction innovation, however, there is limited research into understanding how innovation is perceived and narrated in practice.  The paper aims to explore how innovation is assessed and narrated in construction, specifically analysing theory and practice perspectives.  A theoretical model was constructed from a structured literature review illustrating existing discourse and narratives of construction innovation assessment.  A qualitative analysis of ‘Professional Excellence in Building’ submission documents to the Australian Institute of Building was performed to identify the practice perspective of innovation.  The findings suggest that internal organizational and process innovation account for the majority of improvements identified.  Importantly a taxonomy of narrative is developed that articulates how the construction industry in Australia views industry innovation.

Use of carbon dioxide as a reaction medium in the thermo-chemical process for the enhanced generation of syngas and tuning adsorption ability of biochar

Highlights: • Utilizing CO_2 as a reaction medium in thermo-chemical conversion of aquatic biomass. • Enhanced generation of syngas in the presence of CO_2. • Considerable reduction of pyrolytic oil in CO_2-assisted pyrolysis. • Generation of biochar with high surface area and more porous structure by CO_2. - Abstract: This study mechanistically investigated the influences of CO_2 on syngas (H_2 and CO) production during thermo-chemical conversion of red seaweed, and further explored the possible utility of the produced biochar as a medium for adsorption of inorganic/organic contaminants in aqueous phase. In order to elucidate the key roles of CO_2 in the thermo-chemical process, the composition analysis of syngas and the qualitative analysis of pyrolytic oil were conducted and compared with those in pyrolysis in N_2 condition. Pyrolysis of red seaweed in the presence of CO_2 led to the enhanced generation of syngas at the entire experimental temperatures. For example, the ratio of CO to H_2 in the presence of CO_2 at 620 °C was enhanced by ∼400%, as compared to the case in N_2. This enhanced generation of syngas resulted in significant pyrolytic oil reduction by ∼70% at 620 °C via the unknown reactions between VOCs and CO_2. In addition, biochar generated in the CO_2 environment exhibited comparatively higher surface area (61 m"2 g"−"1) and more porous structure. The morphological modification induced by CO_2 provided the favorable condition for removal of methylene blue from the aqueous phase. Thus, this study experimentally demonstrated that exploiting CO_2 as a reaction medium would provide an attractive option for the enhanced generation of syngas and the tuned adsorption capability of biochar.

A Global Perspective on Small and Medium Reactor Designs

International Nuclear Information System (INIS)

Majumdar, D.; Kupitz, J.

2002-01-01

In the beginning, nuclear power plants were designed for what are now considered small reactors. Then the size increased because of economy of scale, and eventually large reactors in the range of 700 to 1500 MWe size were designed and constructed. However, since the early 1990s the interest in many countries with small and medium electricity grids, mainly in Asia and Eastern Europe, has resulted in increased efforts on designing and developing small (less than 300 MWe) and medium (less than 700 MWe) sized reactors (SMRs). SMRs are also of interest for remote locations, for non-electric applications for desalination and district heating, and for hydrogen production in the future. In addition, globalisation of world economy, deregulation of electricity markets, privatisation of the electricity sector, the drive for energy independence and flexibility, increased concerns for the environment, non-proliferation and awareness of sustainable development have forced new work for innovative designs. This paper will discuss the status of innovative reactor developments in the world. (author)

Using Ring Strain to Control 4π-Electrocyclization Reactions: Torquoselectivity in Ring Closing of Medium-Ring Dienes and Ring Opening of Bicyclic Cyclobutenes.

Boon, Byron A; Green, Aaron G; Liu, Peng; Houk, K N; Merlic, Craig A

2017-05-05

Syntheses of strained cyclic dienes were accomplished via palladium(II)-catalyzed oxidative cyclizations of terminal bis(vinylboronate esters). The reactions generate strained (E,E)-1,3-dienes that undergo spontaneous 4π-electrocyclizations to form bicyclic cyclobutenes. Formation of the cyclobutenes is driven by the strain in the medium-ring (E,E)-1,3-diene intermediate. Thermal ring openings of the cyclobutenes give (Z,Z)-1,3-diene products, again for thermodynamic reasons. DFT calculations verified the thermodynamic versus kinetic control of the reactions, and kinetic studies are in excellent agreement with the calculated energy changes. An extension of the tandem coupling/4π-electrocyclization pathway was demonstrated by a palladium(II)-catalyzed oxidative homocoupling/8π-electrocyclization cascade.

Full Text Available The paper provides an investigation of medium-sized Italian industrial enterprises that have become multinational companies. It concetrates on the set of medium and medium-large enterprises who seem to grow more in foreign markets, either through exports or through foreign direct investment. The work also offers a descriptive empirical picture of the performance of medium-sized Italian multinationals, which is compared with the performance of large corporations. From this analysis, which is based on several data sources, it is possible to outline a profile regarding the medium-size italian multinational enterprises; the aim is to understand the complex strategy towards internationalization of these companies, where the dimension of production is important and, therefore, innovation has a key role. Also the commercial dimension is crucial, because it leads to point to the direct supervision of foreign markets and to look very carefully at the customers, offering them a wide range of services. Finally, the paper highlights some critical issues that the medium sized multinational enterprises have to face for competing: namely, the stagnant productivity, the high taxation, the insufficient institutional support for internationalization, the bureaucracy and its high costs, the lack of skilled human capital available in the labor market due to inadequate policy training.

2015-02-01

Full Text Available Previous research studies on innovation tend to focus on process and product innovations. Recent theoretical opinions reveal that Organizational and Marketing Innovations (OMIs could be the necessary prerequisites to optimally utilize and deploy such process and product innovations. It is important to note that there is a dearth of information on the enablers of OMIs capabilities among small and medium-sized enterprises (SMEs. Despite their closeness to their customers, many SMEs are finding it difficult to achieve successful and effective innovations; these are innovations that have a positive impact on the business growth and returns. This study presents findings from exploratory qualitative research conducted in South-Western Nigeria. Drawing upon information-rich evidence from 13 in-depth interviews with the owners and the managers of SMEs, this study identifies some enablers that can promote SMEs’ OMIs capabilities, effective innovations, and organizational survival.

2011-01-01

Full Text Available The kinetics of oxidation of isoleucine with N-bromophthalimide has been studied in perchloric acid medium potentiometrically. The reaction is of first order each in [NBP] and [amino acid] and negative fractional order in [H+]. The rate is decreased by the addition of phthalimide. A decrease in the dielectric constant of the medium increases the rate. Addition of halide ions or acrylonitrile has no effect on the kinetics. Similarly, variation of ionic strength of the medium does not affect the reaction rate. The reaction rate has been determined at different temperatures and activation parameters have been calculated. A suitable mechanism involving hypobromous acid as reactive species has been proposed.

Impact assessment of agricultural innovations: a review

Directory of Open Access Journals (Sweden)

Juan Carlos Barrientos-Fuentes

2013-04-01

Full Text Available The current conditions of the markets and favorable policies, as well as the progress of science and communications, are promoting further development and diffusion of agricultural innovations, which have effects on different areas of agrarian development. The objective of this paper is to present a review of characteristics of agricultural innovations and their diffusion, adoption and impacts, as well as an update of the types and methods of assessment. Agricultural innovations are not only new or improved products, they are also models and systems, and should have a positive social effect. Innovation areas in developing countries are more concentrated on production and distribution, whereas developed countries concentrate on offering inputs. Investments from the private sector in agricultural innovations are growing faster than those from the public sector. The adoption of innovations is medium-term, and usually less than 100%. The impact of innovations includes intermediate areas, such as institutional, political, scientific and productive areas. The economic efficiency of the investment in innovations is the most often mentioned purpose of impact assessments in the literature. The efficiency analysis (ex-post and its surplus approach is still the most used method for assessing impact of agricultural innovations. Nevertheless, other goals are becoming more important, such as food security, environmental protection and poverty reduction. Livelihood, comprehensive and multidimensional approaches go beyond the economic approach. Moreover, specific models with advantages of prognosis and improved precision are replacing or complementing the classic socio-economic approach

Shivani; Pandey, Parmanad; Misra, Alka; Tandon, Poonam

2017-08-01

The interstellar medium, the vast space between the stars, is a rich reservoir of molecular material ranging from simple diatomic molecules to more complex, astrobiologically important molecules such as amino acids, nucleobases, and other organic species. Radical-radical and radical-neutral interaction schemes are very important for the formation of comparatively complex molecules in low temperature chemistry. An attempt has been made to explore the possibility of formation of complex organic molecules in interstellar medium, through detected interstellar molecules like CH3CN and HCOOH. The gas phase reactions are theoretically studied using quantum chemical techniques. We used the density functional theory (DFT) at the B3LYP/6-311G( d, p) level. The reaction energies, potential barrier and optimized structures of all the geometries, involved in the reaction path, has been discussed. We report the potential energy surfaces for the reactions considered in this work.

Products, practices and processes: exploring the innovation potential for low-carbon housing refurbishment among small and medium-sized enterprises (SMEs) in the UK construction industry

International Nuclear Information System (INIS)

Killip, Gavin

2013-01-01

Scenario-based studies agree that the technical potential for CO 2 emissions reduction from the housing stock is large. This paper explores how a market might be developed for the refurbishment activities assumed in these scenarios, taking the existing market for repair, maintenance and improvement (RMI) as its starting point. Interviews with 16 small and medium-sized enterprises (SMEs) in the construction industry reveal the interdependence of products, practices and processes in housing renovation activities. Conservative practice as well as innovation can be understood as the outcome of multi-lateral influences on firms from other firms, clients, the material buildings and products in their working lives, and from regulations and regulators. Contractors' openness to innovation is contingent on an informal approach to risk assessment, taking account of cost, time efficiency, client demands, and installer confidence in the reliability of the resulting work. The implications of the research are discussed in relation to the need for new practices and processes on refurbishment projects, raising questions for future research on key questions of quality assurance, performance over time, the application of standards, and vocational training. -- Highlights: •Repair, maintenance and improvement works are triggers for low-carbon refurbishment. •Millions of property owners and small firms make for fragmented decision-making. •Actor-Network Theory is used to frame decision-making processes for refurbishment. •Small builders can be innovative if clients allow time and money for experimentation. •Energy policy for existing homes needs to engage with the construction sector

Innovation and Entrepreneurship in Tourism: The Case of a Danish Caravan Site

Stilling Blichfeldt, Bodil

2009-10-01

Full Text Available The tourism industry contains many small and medium-sized enterprises (SMTEs. Furthermore, the tourism industry is often said to be less innovative than other industries and SMTEs’ lack of motivation, knowledge and resources are often claimed to be the reasons why the industry is not very innovative. At the same time, though, rich and thick data on SMTEs and innovativeness is lacking. In order to contribute to the filling of this knowledge gap, this paper draws on a case company (a Danish caravan site that has been innovative. The study reveals a series of reasons why this specific enterprise has been innovative and further, the paper suggests how these findings may transcend the case company.

The agrarian innovation in Camajuaní: inequities and contradictions?

2016-10-01

Full Text Available The agrarian innovation in Camajuaní shows a group of social problems, despite of being a leading municipality in the production of different crops, tobacco and livestock farming. The article is aimed at characterizing, from a sociological approach, the agrarian innovation in producers of different crops, industrial crops, livestock farming and poultry in Camajuaní. A survey, a semi-structured interview and an analysis of the content were applied to an intentional simple of 39 innovators. The outcomes resulted in: gender and age inequity, variability in the levels of scholarship and the tenure of the land of the farmers for an insufficient cognitive domain of innovation, and predominance of a medium level of innovation for most agrarian practices with a high efficiency but low novelty in the various cultures. The agrarian innovations are affected by the contradiction of lacking a bond to the social innovations, with economical aims and being absent to a local system of innovation, which not only limits its growing and development, but also reflects the lack of projection of local entities and civil society; what put at risk the agrarian, rural, and local development.

The pp → pnπ + reaction is a channel with the largest total cross section for pp collision in COSY/CSR energy region. In this work, we investigate individual contributions from various N* and Δ* resonances with mass up to about 2 GeV for the pp → pnπ + reaction. We extend a resonance model, which can reproduce the observed total cross section quite well, to give theoretical predictions of various differential cross sections for the present reaction at T p = 2.88 GeV. It could serve as a reference for identifying new physics in the future experiments at HIRFL-CSR. (author)

In the framework of the French Act of 28 June 2006 about nuclear materials and waste management, the prototype ASTRID (Advanced Sodium Technological Reactor for Industrial Demonstration), foreseen in operation by the 20's, will have to demonstrate not only the minor actinide transmutation capability, but also the progress made in Sodium Fast Reactor (SFR) technology on an industrial scale, by qualifying innovative options. Some of these options still require improvements, especially in the field of operability and safety. In fact, one of the main issues with the standard steam/water Power Conversion System (PCS) of SFR is the fast and energetic chemical reaction between water and sodium, which could occur in steam generators in case of tube failure. To manage the sodium/water reaction, one way consists in minimizing the impact of such event: hence studies are carried out on steam generator design, improvement of the physical knowledge of this phenomenon, development of numerical simulation to predict the reaction onset and consequences, and associated detection improvement. On the other hand, the other way consists in eliminating sodium/water reaction. In this frame, the CEA contribution to the feasibility evaluation of an alternative innovative PCS (replacing steam/water by 180 bar pressurised nitrogen) is focused on the following main topics: - The parametric study leading to nitrogen selection: the thermodynamic cycle efficiency optimisation on Brayton cycles is performed with several gases at different pressures. - The design of innovative compact heat exchangers for the gas loop: here the key points are the nuclear codification associated with inspection capability, the innovative welding process and the thermal-hydraulic and thermal-mechanic optimisations. After a general introduction of the ASTRID project, this paper presents in detail these different feasibility studies being led on the innovative gas PCS for an SFR. (authors)

Full Text Available In a market economy that constantly changes, companies are constrained to adopt efficient solutions to facilitate the achievement of the medium and long term objectives and also to run faster management processes. One of the most efficient methods in this direction is the usage of "innovative products". Those products are distinguished by the high degree of originality and innovation, providing thus a more dynamic framework in management decisions. In order for the usage of innovative products to become successful, they must reach certain stages related to: development of a strategy for creating a new innovative product; valorization of the internal resources of a company regarding the innovation; creating and launching the innovative product on market; engrossment of new market segments. This paper focuses on software-based products which facilitates making management decision based on obtained high utility data and information.

Full Text Available In economies that are led by innovation, innovativeness and competitiveness are interdependent. If an enterprise and/or economy is competitive in the market it will likely have a high level of innovation management, harmonized with EU standards. A variety of different methodologies is used to assess the innovation capacities of small and medium sized companies, but IMPіrove methodology is widespread in EU countries. It is a benchmarking process which gives, as the final output, a comprehensive report on how to improve and leverage innovation management for profitable growth, which includes a identification of the gaps hampering growth and b the direction in which and how the company should be developed and grown. For the purpose of this paper, IMPіrove methodology was adjusted and simplified to assess the innovation capacity of a single company without benchmarking. The focus of the paper is 22 Serbian companies owned and managed by women, which were included in innovation scanning according to the IMPіrove methodology in 2010. All companies included in the sample employ more than 10 employees. The resulting analysis aims to provide insight into the holistic innovation capacity of the selected companies through four dimensions of the so-called ‘House of Innovation’1. They are: innovation strategy, innovation organization and culture, innovation process (life cycle management, and enabling factors supporting the development of the company’s innovation management. This analysis provides an overview of the innovation management platform necessary to enhance small and medium enterprises’ (SME business performance and competitiveness in the EU market. The analysis also presents the results of research on the gender aspects of the institutions and programmes that support innovativeness and competitiveness in SMEs.

Heat and mass transfer effects on MHD viscoelastic fluid over a stretching sheet through porous medium in presence of chemical reaction

Directory of Open Access Journals (Sweden)

Manoj Kumar Nayak

2016-03-01

Full Text Available An attempt has been made to study the heat and mass transfer effects in a boundary layer flow through porous medium of an electrically conducting viscoelastic fluid subject to transverse magnetic field in the presence of heat source/sink and chemical reaction. It has been considered the effects of radiation, viscous and Joule dissipations and internal heat generation/absorption. Closed form solutions for the boundary layer equations of viscoelastic, second-grade and Walters׳ B′ fluid models are obtained. The method of solution involves similarity transformation. The transformed equations of thermal and mass transport are solved by applying Kummer׳s function. The solutions of temperature field for both prescribed surface temperature (PST as well as prescribed surface heat flux (PHF are obtained. It is important to remark that the interaction of magnetic field is found to be counterproductive in enhancing velocity and concentration distribution whereas the presence of chemical reaction as well as porous matrix with moderate values of magnetic parameter reduces the temperature and concentration fields at all points of flow domain.

Managing Innovation under Time Pressure: A Practical Perspective

Directory of Open Access Journals (Sweden)

Blair Winsor

2012-08-01

Full Text Available This article examines the effects of time pressure on innovation. Does time pressure stimulate or eliminate innovation or, in other words, should managers increase or reduce time pressures if they are trying to enhance innovation in their firms? Unfortunately, current research on the subject is ambivalent. To provide some clarity, this innovation management dilemma was examined in a fast-growing, medium-sized communication and IT consultancy (“First”, which claimed to be “highly innovative”. Detailed data on five projects was collected over an 18-month period using practice-based methods. Each project team was followed in real time via observation and interviews. The data was then analyzed by dividing project work into three phases: i negotiating the project particulars with the client; ii conducting project work; and iii project evaluation. This detailed analysis revealed how time pressures eliminated innovation in First’s client-based project work and suggested three implications for the management of innovation. Firstly, managers should try to avoid imposing excessive time pressures on their project teams. Secondly, they should ensure that there is space between projects to enable reflection. Thirdly, managers should ensure that project debriefs occur and that they cover potential innovations.

Mechanistic Investigation of Oxidation of Phenylpropanolamine with N-Bromobenzenesulfonamide in Alkaline Medium: A Kinetic Approach

Directory of Open Access Journals (Sweden)

Ningegowda Prasad

2008-01-01

Full Text Available The kinetics of oxidation of phenylpropanolamine (PPA with sodium N-bromobenzenesulfonamide or bromamine-B (BAB has been investigated in alkaline medium at 308 K. The oxidation reaction obeys the rate law, – d[BAB]/dt = k [BAB] [PPA]x [OH-], where x is less than unity. The variation of ionic strength of the medium, addition of the reduction product, benzenesulfonamide, and chloride ion had no pronounced effect on the reaction rate. Decrease of dielectric permittivity of the medium by increasing the CH3CN content increased the rate. The reaction was studied at different temperatures and the activation parameters have been evaluated from the Arrhenius plot. The stiochiometry of the reaction was found to be 1:1, and the oxidation product of phenylpropanolamine was identified as benzaldehyde and ethylideneamine. The rate decreased in D2O medium and the normal isotope effect k' (H2O / k' (D2O is 2.18. Proton inventory studies have been made in H2O - D2O mixtures. Formation and decomposition constant of BAB-PPA complexes in the reaction scheme have been determined. The conjugate acid, C6H5SO2NHBr is assumed to be the reactive species. The proposed mechanism and the derived rate law are consistent with the observed experimental results.

Innovation in nuclear energy technology

Dujardin, Th.; Bertel, E.; Kwang Seok, Lee; Foskolos, K.

2007-01-01

Innovation has been a driving force for the success of nuclear energy and remains essential for its sustainable future. Many research and development programmes focus on enhancing the performance of power plants in operation, current fuel design and characteristics, and fuel cycle processes used in existing facilities. Generally performed under the leadership of the industry. Some innovation programmes focus on evolutionary reactors and fuel cycles, derived from systems of the current generation. Such programmes aim at achieving significant improvements, in the field of economics or resource management for example, in the medium term. Often, they are undertaken by the industry with some governmental support as they require basic research together with technological development and adaptation. Finally, large programmes, often undertaken in an international, intergovernmental framework are devoted to design and development of a new generation of systems meeting the goals of sustainable development in the long term. Driving forces for nuclear innovation vary depending on the target technology, the national framework and the international context surrounding the research programme. However, all driving factors can be grouped in three categories: market drivers, political drivers and technology drivers. Globally, innovation in the nuclear energy sector is a success story but is a lengthy process that requires careful planning and adequate funding to produce successful outcomes

Process and apparatus for reacting laser radiation with a reactive medium

International Nuclear Information System (INIS)

Vanderleeden, J.C.

1980-01-01

The invention is based on the concept of irradiating the reaction medium with laser radiation in a reaction zone bounded by two longitudinally spaced reflecting surfaces, the beam of laser radiation being reflected back and forth between the surfaces which are contoured in such a way that the radiation flux density profile at substantially all transverse cross sections of the reaction zone is matched to the transverse distribution profile, that is the transverse distribution of the availability of a reactive species in the medium. A necessary condition for achieving this is that the beam be successively reflected between the surfaces along successive paths of progressively changing cross-sectional area intersected by respective, contiguous, non-overlapping areas of these surfaces. This process may be applied in particular to the selective laser-induced decomposition of HDCO to yield HD and CO

Saponification reaction system: a detailed mass transfer coefficient determination.

Pečar, Darja; Goršek, Andreja

2015-01-01

The saponification of an aromatic ester with an aqueous sodium hydroxide was studied within a heterogeneous reaction medium in order to determine the overall kinetics of the selected system. The extended thermo-kinetic model was developed compared to the previously used simple one. The reaction rate within a heterogeneous liquid-liquid system incorporates a chemical kinetics term as well as mass transfer between both phases. Chemical rate constant was obtained from experiments within a homogeneous medium, whilst the mass-transfer coefficient was determined separately. The measured thermal profiles were then the bases for determining the overall reaction-rate. This study presents the development of an extended kinetic model for considering mass transfer regarding the saponification of ethyl benzoate with sodium hydroxide within a heterogeneous reaction medium. The time-dependences are presented for the mass transfer coefficient and the interfacial areas at different heterogeneous stages and temperatures. The results indicated an important role of reliable kinetic model, as significant difference in k(L)a product was obtained with extended and simple approach.

It is shown that the previously anticipated requirement of high pellet velocities can be substantially reduced; the toroidal field (TF) ripple requirements may be relaxed to reduce the number of TF coils and improve machine access; hybrid equilibrium field (EF) coils have been shown to require building only small interior coils and to reduce the power supply required by the exterior coils; proper approaches of microwave plasma preheating may reduce the peak loop voltage for start-up by an order of magnitude. The medium-field TNS reactor concepts and the plasma engineering innovations discussed should be applicable to other designs of tokamak reactors

Full Text Available The aim of this study is the process of open innovation in the growth development of a technologybased company. We used the case study method to research Totvs, a company that is the largest producer of information systems in Latin America, for medium and small businesses, as an illustrative case to support the evidences of new approaches to implement the open innovation processes. The main conclusions regarding the expansion of the open innovation concept can be seen taking the following distinct factors into account: (a technological dominion, not business protection, is the main motivator for acquisition of external technologies, directly or through other enterprises acquisition, (b adherence to technological footprint is the main inducer of the open innovation processes, (c market pull technologies determines the length and range of technological dominion, and (d incremental instead of radical type of innovation would be the preferred way to implement the open innovation process.

Pre-equilibrium emission of nucleons from reactions induced by medium-energy heavy ions

Korolija, M.; Holuh, E.; Cindro, N.; Hilscher, D.

1984-01-01

Recent data on fast-nucleon emission in heavy-ion-induced reactions are analysed successfully in terms of pre-equilibrium models; it is shown that the relevant parameters of those models preserve the physical meaning they have in light-ion-induced reactions. The initial exciton number obtained from a Griffin-plot analysis and the initial number of degrees of freedom, which is the relevant parameter of the modified HMB model, appear to be approximately equal for a given reaction at a given energy. It is inferred that, for heavy-ion reactions, the determination of such a parameter is substantially dominated by the centre-of-mass energy per nucleon above the Coulomb barrier, in contrast with the results of nucleon-induced reactions

The role of employee participation in generating and commercializing innovations in China

Kesting, Peter; Qin, Zhihua; Song, Jiwen Lynda

2013-01-01

In this paper we are investigating the effect of different forms of employee participation on innovation generation and commercialization in China. To date, the concept of employee-driven innovation (EDI) finds very little recognition in China, in research as well as in management practice....... It seems to fundamentally contradict traditional values in Chinese culture. On the other hand, work realities change rapidly in China. Research suggests that EDI might be particularly relevant for innovations in skilled labour contexts. Based on a survey of 620 medium-sized and large companies in China we...... underpin that EDI is also relevant for China....

Park, Sungmin

2014-01-01

This study analyzes the efficiency of small and medium-sized enterprises (SMEs) of a national technology innovation research and development (R&D) program. In particular, an empirical analysis is presented that aims to answer the following question: "Is there a difference in the efficiency between R&D collaboration types and between government R&D subsidy sizes?" Methodologically, the efficiency of a government-sponsored R&D project (i.e., GSP) is measured by Data Envelopment Analysis (DEA), and a nonparametric analysis of variance method, the Kruskal-Wallis (KW) test is adopted to see if the efficiency differences between R&D collaboration types and between government R&D subsidy sizes are statistically significant. This study's major findings are as follows. First, contrary to our hypothesis, when we controlled the influence of government R&D subsidy size, there was no statistically significant difference in the efficiency between R&D collaboration types. However, the R&D collaboration type, "SME-University-Laboratory" Joint-Venture was superior to the others, achieving the largest median and the smallest interquartile range of DEA efficiency scores. Second, the differences in the efficiency were statistically significant between government R&D subsidy sizes, and the phenomenon of diseconomies of scale was identified on the whole. As the government R&D subsidy size increases, the central measures of DEA efficiency scores were reduced, but the dispersion measures rather tended to get larger.

2015-12-01

Full Text Available The oxidation of aspartame (ASP by diperiodatocuprate(III (DPC in aqueous alkaline medium at 298 K and a constant ionic strength of 0.30 mol dm−3 was studied spectrophotometrically. The reaction between aspartame and diperiodatocuprate(III in alkaline medium exhibits 1:6 stoichiometry in the reaction. The order of the reaction with respect to [diperiodatocuprate(III] was unity, while the apparent order with respect to [aspartame] was less than unity over the concentration range studied. The rate of the reaction increased with increase in [OH−] whereas the rate decreased with increase in [$ {\\text{IO}}^-_4 $]. Increasing the ionic strength of the medium increased the rate. The main products were identified by FT-IR, NMR, and LC-MS spectral studies. The probable mechanism was proposed. The activation parameters with respect to slow step of the mechanism were computed and discussed. Thermodynamic quantities were also calculated. Kinetic studies suggest that [Cu(H2IO6(H2O2] is the reactive species of Cu(III.

Pulse radiolytic study of the reaction OH + O3 in aqueous medium

Sehested, K.; Holcman, J.; Bjergbakke, E.; Hart, E.J.

1984-01-01

In slightly alkaline solution the ozonide radical ion, O 3 - , forms as a product of the hydroxyl radical reaction with ozone. For each O 3 - formed, two O 3 molecules are consumed. In acid solution the product of this reaction is the perhydroxyl radical, HO 2 , formed from one O 3 molecule. Our results are consistent with the gas-phase reaction where the products are HO 2 and O 2 . A rate constant of (1.1 +/- 0.2) x 10 8 dm 3 mol -1 s -1 is found for the reaction OH + O 3 → HO 2 + O 2 . This rate constant was obtained by three systems, by buildup of O 3 - in basic solutions, by competition of the OH radical with the carbonate ion, and directly by O 3 consumption in acid solution. The rate constant for the reaction of HO 2 with O 3 is very low, 4 dm 3 mol -1 s -1 . At pH greater than or equal to 1, HO 2 reacts with O 3 preferentially in its dissociated form, O 2 - . No spectroscopic evidence has been found for the HO 3 and HO 4 free-radical intermediates. 24 references, 4 figures, 2 tables

Redox reactions of neptunium in tributyl phosphate-dodecane mixtures

International Nuclear Information System (INIS)

Wehrey, F.

1989-01-01

In relation with the reprocessing of irradiated fuels, disproportionation and oxidation by nitric acid of pentavalent neptunium in tributyl phosphate-dodecane mixtures have been studied. The experimental part of this work is based on spectrophotometric measurements. The disproportionation of pentavalent neptunium in organic perchloric medium is a second order reaction with respect to neptunium V. The reaction rate is strongly influenced by the perchloric acid concentration and has a higher value than in an aqueous medium. The reverse reaction in nitric media is a first order with respect to tetravalent and hexavalent ions. The reaction rate is a function of the reverse of the square of the nitric acid concentration. The energy of activation is the same than in aqueous medium. The oxidation rate of pentavalent neptunium by nitric acid is increased by nitrous acid. When no nitrous acid is added to the mixture, the reaction revealed to be autocatalytic, possesses an induction period. When nitrous and nitric acids are in excess to neptunium the reaction is first order with respect to neptunium. The reaction rate depends on the concentration of nitric acid and is a linear function of the concentration of nitrous acid. In tributyl phosphate dodecane mixtures the reaction occurs spontaneously. It is not the case in aqueous media. The values of thermodynamical and kinetical constants determined in this work could be used in a modelization of the behavior of neptunium in the reprocessing of irradiated fuels, which has to eliminate this element among its tasks [fr

Zavialov, Ivan; Konyukhov, Andrey; Negodyaev, Sergey

2015-04-01

An experimental and numerical study of filtration accompanied by chemical reactions between displacing fluid and solid skeleton is considered. Glass balls (400-500 μm in diameter) were placed in 1 cm gap between two glass sheets and were used as model porous medium. The baking soda was added to the glass balls. The 70% solution of acetic acid was used as the displacer. The modeling porous medium was saturated with a mineral oil, and then 70% solution of colored acetic acid was pumped through the medium. The glass balls and a mineral oil have a similar refractive index, so the model porous medium was optically transparent. During the filtration, the gas phase was generated by the chemical reactions between the baking soda and acetic acid, and time-dependent displacement of the chemical reaction front was observed. The front of the chemical reaction was associated with the most intensive gas separation. The front moved, stopped, and then moved again to the area where it had been already. We called this process a secondary oxidation wave. To describe this effect, we added to the balance equations a term associated with the formation and disappearance of phases due to chemical reactions. The equations were supplemented by Darcy's law for multiphase filtration. Nonstationarity front propagation of the chemical reaction in the numerical experiment was observed at Damköhler numbers greater than 100. The mathematical modelling was agreed well with the experimental results.

2005-01-01

The fabrication of medium carbon steel-matrix composites locally reinforced with in situ TiB 2 -TiC particulates using self-propagating high-temperature synthesis (SHS) reaction of Ni-Ti-B 4 C system during casting was investigated. X-ray diffraction (XRD) results reveal that the exotherm of 1042 deg. C initiated by heat release of the solid state reaction in the differential thermal analysis (DTA) curve is an incomplete reaction in Ni-Ti-B 4 C system. As-cast microstructures of the in situ processed composites reveal a relatively uniform distribution of TiB 2 -TiC particulates in the locally reinforced regions. Furthermore, the particulate size and micro-porosity in the locally reinforced regions are significantly decreased with the increasing of the Ni content in the preforms. For a Ni content of 30 and 40 wt.%, near fully dense composites locally reinforced with in situ TiB 2 and TiC particulates can be fabricated. Although most of fine TiB 2 and TiC particulates which form by the reaction-precipitation mechanism during SHS reaction are present in the locally reinforced region, some large particulates which form by the nucleation-growth mechanism during solidification are entrapped inside the Fe-rich region located in the reinforcing region or inside the matrix region nearby the interface between matrix and reinforcing region. The hardness of the reinforcing region in the composite is significantly higher than that of the unreinforced medium carbon steel. Furthermore, the hardness values of the composites synthesized from 30 to 40 wt.% Ni-Ti-B 4 C systems are higher than those of the composites synthesized from 10 to 20 wt.% Ni-Ti-B 4 C systems

To prepare a series of vanadium cyclopentadienylcarboxylates soluble in water, the vanadocene reactions with lactic, γ-oxybutyric-, salicylic,- gallic-, orotic-, and acetylsalicylic acids have been studied. To determine the influence of cyclopentadienyl groups, bound with a vanadium atom, on the physiological activity of the complexes formed, vanadium halides are made to react with lactic acid. Only the vanadocene reaction with orotic acid was conducted in an aqueous medium, other interactions were realized in the diethyl ether, toluene, T, H, P medium. The interaction of vanadocene and vanadium halides with lactic-, salicylic-, acetylsalicylic- and gallic acids was found to lead to the formation of water-soluble vanadium complexes of Cp 2 , VOCOR or CpV (OCOR) 2 type. The data on the produced compounds yield, their IR spectra, decomposition temperatures, solubility, effective magnetic moments are presented

2017-01-01

Full Text Available Purpose: the purpose of this study is to present the results of the analysis of the state of innovative development of the economy, identify the reasons that impede such development, and assess prospects for the medium term.Methods: the methodology of the work is based on a comprehensive statistical analysis of the dynamics of the effectiveness of innovation activities, as well as assessing the impact of innovation on technological development. To identify the reasons hindering innovative development, the methods of constructing information-logistic models were used, which allow establishing significant interrelationships in the chain of "shortcomings – causes – ways to overcome them." At the same time, the methods of system design of the progressive economy model were used, in the case of which it is possible to reduce the identified shortcomings.Results: concluded in the comparative evaluation of the results of innovation activities and their impact on the processes of technological development in Russia. Also listed are the main reasons that inhibit innovation development.Conclusions and relevance: possibilities of positive influence of the innovation sphere on the recovery of economic growth essentially depend on the duration of the time interval. In the near future (1–3 years, such influence is extremely limited, and probably, first of all, with the import substitution of components in the interests of the military-industrial complex. Useful participation in the restoration of economic growth in the near future can take the previously performed, so-called "sleeping innovations and technologies".However, it is important to maintain renewable growth rates in the medium term. To do this, the innovation sector should be oriented towards solving problems in certain, most priority areas. Moreover, the mechanism of such orientation can be represented in the form of feedback of an innovative reproduction circuit, the mandatory components of

2007-01-01

Kinetic of the redox reaction between tris (2,2-bipyridine)iron(II) cation and ceric sulphate has been studied in aqueous sulphuric acid medium. Different methods were employed for the determination of order of reaction. The order of reaction is found to be first with respect to reductant however retarding effect of increasing initial concentration of oxidant is found. Influence of (H/sup +/), (SO/sub 4/sup 2-) and dielectric constant (D) on the rate of redox reaction has also been studied. Increase in (H/sup +/) and dielectric constant of the medium retard the rate while enhancement of the (SO/sub 4/sup 2-/) accelerates the rate first and then the reaction goes towards retardation. Effects of (H/sup +/) and (SO/sub 4/sup 2-/) were studied by using acetic acid-sodium acetate buffer for the first one and varying ionic concentrations of the salt sodium sulphate for the latter one, whereas dielectric constant was varied by using 0%, 10% and 20% ethanol-water mixtures. Results of effects of each one of the factors i.e., H/sup +/, SO/sub 4/sup 2-/ and dielectric constant (D) have been compared and on the basis of these factors, (Ce(SO/sub 4/ )/sub 3/)/sup 2-/ is suggested to be the active species of cerium(IV). However a rate law consistent with the observed kinetic data has also been derived supporting the proposed mechanism. (author)

Open innovations, innovation communities and firm's innovative activities

Directory of Open Access Journals (Sweden)

Getejanc Vesna

2016-01-01

Full Text Available The open innovation paradigm emphasizes the fact that firms can improve their performance by opening their business models and reduce their R&D costs by effective incorporation of external knowledge. In other words, companies are able to capture value through knowledge that exists outside the boundaries of their organization. The shift from closed to open model of innovation has imposed the necessity to adopt more open approach to innovation within traditional academic view of business strategy. The adoption of this innovative approach is emphasized even more, by the necessity for stronger connection and cooperation among the participants of the innovation process. Free will and collaboration are the main characteristics of open source software, which is recognized in literature as the role model of open innovation and is a rapidly growing method of technology development. Furthermore, innovative communities represent a great opportunity for improvement of the companies' innovation activities, since they have become an important source for identifying the needs and problems of the users. Their development has been fostered by information technologies and recent social changes in user behavior. Recognizing and better understanding the motivation of the members of the innovation communities that guide them to participate in the process of idea generation, can have significant influence on their incorporation within the innovation process. Equally important is to define the incentives that are suited for stimulating and fostering innovative user activities. Taking this topic in consideration, the purpose of this article is to address the following questions: In what way does the collaboration in open source software projects have positive effect on companies' innovation performance? What are the innovation communities and how can companies establish successful interaction with them? Why does the interaction with innovation communities lead to

Innovation Management Practices, Strategic Adaptation, and Business Results: Evidence from the Electronics Industry

Directory of Open Access Journals (Sweden)

Alba Sánchez

2011-06-01

Full Text Available This research contributes to the understanding of how different practices of innovation management are related to mid- and long-term growth and profitability. Governments and regional development agencies invest relevant budgets to foster innovation in small and medium enterprises (SMEs and improve their innovation management practices to make them more competitive. Nevertheless, it is not clear what impact these practices have on a company's performance over a long period of time. We propose a model to audit and classify innovation practices and empirically test the impact of innovation practices on the firms’ long–term financial performance, using a broad sample of companies in the electronics sector. Our empirical results show that, within a regional context, companies that are similar in terms of size, position in the value chain, and ownership structure follow similar innovative practices. Furthermore, the use of a systematic approach for innovation leads to revenue growth but does not necessarily increase profit or productivity.

Full Text Available In 2005 Deloitte Research released a paper examining the phenomenon they refer to asthe ‘innovation paradox’: the inability or reluctance of manufacturing firms to pursuestrategies that build the operational capabilities necessary for innovation that willprovide both profitability and growth. The report claims that this is due to the rapidlyincreasing complexity of global markets and the lack of synchronising innovation effortsacross their value chain, thus positioning the problem as an important contemporaryissue. While the research did not specifically target small and medium enterprises, theimplications for this business sector are considerable given their substantial contributionto global economies and their high failure rates in the first three to five years ofoperation. While not questioning the data in the Deloitte research, this paper doesquestion the assumption that the phenomenon is irreversible and the apparentunderlying self-fulfilling prophecy with respect to small to medium enterprises. Todemonstrate this the authors draw on a case study of a small manufacturing company inrural New South Wales, Australia, which operated between 1889 and 1983, to show thatthe breaking of the innovation paradox was successfully achieved by this firm in the latenineteenth and early twentieth century. Applying the case study to the Deloitte modelthe study demonstrates contemporary similarities by overlaying the Laycock history onthe successes / failures identified by Deloitte.

The effect of initial water activity of MTBE (methyl tert-butyl ether) medium on CALB (Candida antarctica lipase B) catalyzed esterification reaction is investigated using experimental methods and classical molecular dynamics (MD) simulations. The experimental kinetic studies show that the initial...... reaction rate of CALB-catalyzed esterification reaction between butyric acid and ethanol decreases with increasing initial water activity of the medium. The highest rate of esterification is observed at the lowest water activity studied. MD simulations were performed to gain a molecular insight...... on the effect of initial water activity on the rate of CALB-catalyzed reaction. Our results show that hydration has an insignificant effect on the structure and flexibility of CALB. Rather, it appears that water molecules bind to certain regions ("hot spots") on the CALB surface and form clusters. The size...

Open Innovation Projects in SMEs as an Engine for Sustainable Growth

Directory of Open Access Journals (Sweden)

Byungun Yoon

2016-02-01

Full Text Available Most innovation activities that are inevitable for sustainable growth are coordinated via research and development (R&D projects, which can differ widely in terms of both project and open innovation characteristics, even when conducted within the same firm. Therefore, it is important to consider the peculiarities of R&D projects when evaluating the performance of open innovation strategies, as well as to explore how the benefits and costs of open innovation are shaped by cross-level interactions. This study identifies the differences between successful and unsuccessful open innovation projects, in both firm-level and project-level terms. We focus on small and medium enterprises (SMEs, which usually lack the full set of internal resources and competences required to effectively develop, produce, and commercialize their innovations, and thus must adopt open innovation approaches more actively for sustainability. Adopting an empirical approach, we conducted a survey of 517 Korean SMEs and analyzed 241 successful and unsuccessful open innovation projects in depth. By combining measurements at the firm and project levels, this study provides new insight into the intra-organizational challenges of implementing open innovation projects, which are not only helpful to strategic decision-makers in SMEs, but also to those who make policies for them.

The numerical simulation of aerosol transport, including the effects of chemical and nuclear reactions presents a challenging dynamic accounting problem. Particles of different sizes agglomerate and settle out due to various mechanisms, such as diffusion, diffusiophoresis, thermophoresis, gravitational settling, turbulent acceleration, and centrifugal acceleration. Particles also change size, due to the condensation and evaporation of materials on the particle. Heterogeneous chemical reactions occur at the interface between a particle and the suspending medium, or a surface and the gas in the aerosol. Homogeneous chemical reactions occur within the aersol suspending medium, within a particle, and on a surface. These reactions may include a phase change. Nuclear reactions occur in all locations. These spontaneous transmutations from one element form to another occur at greatly varying rates and may result in phase or chemical changes which complicate the accounting process. This paper presents an approach for inclusion of these effects on the transport of aerosols. The accounting system is very complex and results in a large set of stiff ordinary differential equations (ODEs). The techniques for numerical solution of these ODEs require special attention to achieve their solution in an efficient and affordable manner. 4 refs

Coupled processes of fluid flow, solute transport, and geochemical reactions in reactive barriers

A complex pattern of coupling between fluid flow and mass transport develops when heterogeneous reactions occur. For instance, dissolution and precipitation reactions can change a porous medium's physical properties, such as pore geometry and thus permeability. These changes influence fluid flow, which in turn impacts the composition of dissolved constituents and the solid phases, and the rate and direction of advective transport. Two-dimensional modeling studies using TOUGHREACT were conducted to investigate the coupling between flow and transport developed as a consequence of differences in density, dissolution precipitation, and medium heterogeneity. The model includes equilibrium reactions for aqueous species, kinetic reactions between the solid phases and aqueous constituents, and full coupling of porosity and permeability changes resulting from precipitation and dissolution reactions in porous media. In addition, a new permeability relationship is implemented in TOUGHREACT to examine the effects of geochemical reactions and density difference on plume migration in porous media. Generally, the evolutions in the concentrations of the aqueous phase are intimately related to the reaction-front dynamics. Plugging of the medium contributed to significant transients in patterns of flow and mass transport.

2014-12-01

Full Text Available Studies of small and medium-sized enterprise (SMEs development around the world show that the most significant factor for increasing their numbers and improving business success is the free enterprise, as exogenous, and innovation as an endogenous variable. At the same time, the dominant view in economic theory is that innovation is a key generator of changes for which the SMEs can be considered as a kind of metaphors for a successful business over the last twenty years in a number of economies. Arguing that cooperation between SMEs is increasingly common generic strategy of their development, the paper first explains the importance of collaboration to increase innovation and competitiveness, and then provides possible models using information technology such as Workflow Management Systems (WfMS, Service Oriented Architecture (SOA and Service-Oriented Cloud Computing Architecture (SOCCA to support the collaboration of these business entities. Solutions provided are aimed at improving the innovativeness of SMEs and fully follow the requirements of the so-called fifth-generation innovation process whose key attributes are integration and flexibility.

Contribution of Micro-Small and Medium Enterprises (MSMEs) is highly remarkable in the overall industrial economy of the country. In recent years, the MSME sector has consistently registered higher growth rate compared to the overall industrial sector. With its agility and dynamism, the sector has shown admirable innovativeness and adaptability to survive the recent economic downturn and recession. However, MSMEs growth rate is still at low level. Therefore, it becomes essential for organizations to adopt new technologies or upgrade existing setup to meet continuously changing global market and fulfill customer needs. This paper explores the relationships between different collaboration networks and technological innovation of small firms through an extensive review of literature. The study finds that collaboration with larger enterprises, R and D institutions, universities and government agencies play a significant role in enhancing technological innovation in small firms

Brand, J.F.J. van den; Ent, R.

1994-01-01

The authors show that the virtual Compton scattering process allows for a precise study of the off-shell electron-nucleon vertex. In a separable model, they show the sensitivity to new unconstrained structure functions of the nucleon, beyond the usual Dirac and Pauli form factors. In addition, they show the sensitivity to bound nucleon form factors using the reaction 4He(rvec e,e',rvec p) 3 H. A nucleon embedded in a nucleus represents a complex system. Firstly, the bound nucleon is necessarily off-shell and in principle a complete understanding of the dynamical structure of the nucleon is required in order to calculate its off-shell electromagnetic interaction. Secondly, one faces the possibility of genuine medium effects, such as for example quark-exchange contributions. Furthermore, the electromagnetic coupling to the bound nucleon is dependent on the nuclear dynamics through the self-energy of the nucleon in the nuclear medium

B16 melanoma cells were grown in a flask (Falcon 3031). When the cells reached the latter stage of logarithmic phase, B-boric acid (92 % concentrated 10 B) was added to the flask until 5 μg/ml medium was attained (Medium I). The other medium did not contain 10 B (Medium II). After both media were exposed to thermal neutrons, survival curves were obtained from the colony method and the absorbed dose of the cells were obtained from the mathematical models. Survival curves from the colony method had no shoulders, showing that Do was 0.95 x 10 12 n/cm 2 in Medium I and 3.2 x 10 12 n/cm 2 in Medium II. Do calculated by mathematical models was 0.507 Gy in Medium I and 0.604 Gy in Medium II. REB of thermal neutrons was 3.04 in Medium I and 2.55 in Medium II. REB of 10 B (n, α) 7 Li reaction was 3.30.

Full Text Available SMEs (small and medium-sized enterprises and micro-enterprises are the backbone of the EU economy. Their prosperity is a crucial factor for achieving more growth and more and better jobs in the EU. They are vital to fulfilling the goal of a more equal and productive society with higher social and economic integration. Yet they are often poorly equipped to fulfill their potential as innovators and entrepreneurs, especially in the relentless transition to a knowledge based society, both because of their diverse academic backgrounds and their lack of training. This paper summarizes work currently underway by two diverse teams across Europe to develop and roll out a suite of training and tools to enhance the innovation and collaboration capacities and capabilities of small and micro-businesses.

Adverse reactions to iotroxate at intravenous cholangiography

Nilsson, U.

1987-01-01

The number and type of adverse reactions to meglumine iotroxate at intravenous infusion cholangiography, performed one day prior to elective cholecystectomy, were recorded in a prospective investigation of 196 asymptomatic, anicteric patients. One hundred ml (50 mg I/ml) of contrast medium was infused over a period of 30 minutes. Only 2 minor (1%) and no severe or fatal reactions were noted. A review of the literature on the use of iotroxate in 2492 patients, including those in the present investigation, revealed a complication rate of 3.5% (3.0% minor, 0.3% moderate and 0.2% severe reactions) at infusion of iotroxate (5.0-8.0 g I) over a period of 30 to 120 minutes. This compared favourably with the 5% complication rate (4% minor, 0.5% moderate and 0.5% severe reactions) at infusion of iodoxamate and the 9% complication rate (5% minor, 1% moderate and 3% severe reactions) at infusion of ioglycamide. Irrespective of the contrast agent used, the frequency of adverse reactions at infusion was found to be 3 times lower than when equal amounts (5.0-5.6 g I) of the same medium were injected. It is concluded that, at present, infusion of iotroxate in an amount which approximates to the transportation maximum of the liver is the least toxic way of performing intravenous cholangiography with an optimum filling of the bile ducts.

Full Text Available The aim of this paper is to identify some changes needed in Spain’s innovation policy to fill the gap between its innovation results and those of other European countries in lieu of sustainable leadership. To do this we apply the Delphi methodology to experts from academia, business, and government. To overcome the shortcomings of traditional descriptive methods, we develop an inferential analysis by following a non-parametric bootstrap method which enables us to identify important changes that should be implemented. Particularly interesting is the support found for improving the interconnections among the relevant agents of the innovation system (instead of focusing exclusively in the provision of knowledge and technological inputs through R and D activities, or the support found for “soft” policy instruments aimed at providing a homogeneous framework to assess the innovation capabilities of firms (e.g., for funding purposes. Attention to potential innovators among small and medium enterprises (SMEs and traditional industries is particularly encouraged by experts.

The Impact of Financial Support System on Technology Innovation: A Case of Technology Guarantee System in Korea

2008-04-01

Full Text Available We analyzed the impact of financial support system on technological innovation of small and medium manufacturing firms in Korea, with a special interest in technology guarantee system. This was done using a sample of 1,014 Korean manufacturing firms of which 43% were venture companies. Our study provides two important conclusions. First, the result of empirical analysis indicates that financial support systems have a significant influence on both product innovation and process innovation of SMEs in Korea. Second, a more important conclusion of this research is that technology guarantee system impacts on product innovation; however not on process innovation. This result implies that technology guarantee system attaches more importance to technological innovations related with product development than to those related with process enhancement.

Prevention of adverse reactions to intravascular contrast media

International Nuclear Information System (INIS)

Soyer, P.; Levesque, M.

1990-01-01

The exact mechanisms of adverse reactions to contrast media are still imperfectly known. However, these reactions may be classified as idiosyncratic. Non-idiosyncratic reactions can be prevented by using new, non-ionic contrast agents. Idiosyncratic reactions can be prevented by specific premedication. Patients with a history of idiosyncratic reaction may benefit from corticosteroids and antihistamines administered prophylactically. Patients who seem to be more likely than others to react to contrast media must be premedicated, the risk of reaction being identified and evaluated by questioning. It has recently been suggested that all patients about to receive an intravascular injection of contrast medium should also be premedicated [fr

Innovation in European food SMEs: determinants and links between types

Directory of Open Access Journals (Sweden)

Francesca Minarelli

2015-05-01

Full Text Available The food sector has traditionally been considered one with the lowest research and development expenditure to value added ratio. In recent decades, however, the business environment has become more demanding in terms of technological inputs for reasons related to food safety, quality and also the globalisation of the food market. This provides a strong incentive to innovate, especially for small and medium-sized enterprises (SME seeking to remain in business.Most businesses operating in the food sector belong to the SME category which, based on the literature, tends to have a low level of research capacity.This study seeks to identify determinants of the types of innovation adopted and associations between them by analysing a sample of European food SMEs. For this purpose a non-parametric analysis, namely the classification tree technique, is carried out. The main finding is that due to the technological factors inherent in the food industry, a tight linkage exists between product, process and market innovation. Moreover, the study shows that collaboration between competitors encourages SMEs to engage in market, process and business model innovation. Conversely, synergy with suppliers and customers supports product innovation.

Organizational Well-Being Factors. Determinants of entrepreneurship in small and medium companies of the defense sector

2013-09-01

Full Text Available All over the world, the small and medium enterprises are more and more organized in consortia, cooperation networks, joint-ventures and strategical alliances allowing not only the reduction of uncertainty and turbulence of the markets but also the gathering of advantages which may make them more competitive. It is worth considering that the results of these relationships are affected by determinant factors which may inhibit or facilitate the entrepreneurship. Our aim is to evaluate the relationship between some of those determinants, association, inter-company cooperation, innovation in the methods of work and creativity—about the entrepreneurship in 236 small and medium enterprises of the national defence. One of the questions initially posed is if there is a significant relation between corporation, innovative methods of work, creativity and entrepreneurship. Secondly, if being creative is an attribute of the entrepreneur, can it have a mediator effect between innovative methods of work and entrepreneurship? A factorial exploratory analysis was made in main components (varimax rotation and multiple linear regression. The results show the direct relationship of the evaluated determinants and entrepreneurship and the partial mediator effect of the creativity between the innovation in the methods of work and entrepreneurship. These enterprises may expect to develop new methods of work as a high differential component concerning the competition and the more efficient use of knowledge and of the skills of the people who make part of the work team in order to increase their competitiveness.

The cross sections of a number of target fragmentation products formed in nuclear reactions of 3.65 AGeV 12 C-ions and 3.65 GeV protons with 197 Au have been measured. The measurements have been done by direct counting of irradiated targets with Ge(Li) gamma-spectrometers. Comparison between these and other data has been used to test the hypotheses of factorization and limiting fragmentation. The total cross section for residue production in both reactions indicates that target residues are formed mainly in central collisions

Design features to achieve defence-in-depth in small and medium sized reactors

International Nuclear Information System (INIS)

Kuznetsov, Vladimir

2009-01-01

Broader incorporation of inherent and passive safety design features has become a 'trademark' of many advanced reactor concepts, including several evolutionary designs and nearly all innovative small and medium sized design concepts. Ensuring adequate defence-in-depth is important for reactors of smaller output because many of them are being designed to allow more proximity to the user, specifically, when non-electrical energy products are targeted. Based on the activities recently performed by the International Atomic Energy Agency, the paper provides a summary description of the design features used to achieve defence in depth in the eleven representative concepts of small and medium sized reactors.

Onset of Convection in the Presence of a Precipitation Reaction in a Porous Medium: A Comparison of Linear Stability and Numerical Approaches

Directory of Open Access Journals (Sweden)

Parama Ghoshal

2017-12-01

Full Text Available Reactive convection in a porous medium has received recent interest in the context of the geological storage of carbon dioxide in saline formations. We study theoretically and numerically the gravitational instability of a diffusive boundary layer in the presence of a first-order precipitation reaction. We compare the predictions from normal mode, linear stability analysis, and nonlinear numerical simulations, and discuss the relative deviations. The application of our findings to the storage of carbon dioxide in a siliciclastic aquifer shows that while the reactive-diffusive layer can become unstable within a timescale of 1 to 1.5 months after the injection of carbon dioxide, it can take almost 10 months for sufficiently vigorous convection to produce a considerable increase in the dissolution flux of carbon dioxide.

Velocity and thermal slip effects on MHD third order blood flow in an irregular channel though a porous medium with homogeneous/ heterogeneous reactions

2017-09-01

This communication presents the transportation of third order hydromagnetic fluid with thermal radiation by peristalsis through an irregular channel configuration filled a porous medium under the low Reynolds number and large wavelength approximations. Joule heating, Hall current and homogeneous-heterogeneous reactions effects are considered in the energy and species equations. The Second-order velocity and energy slip restrictions are invoked. Final dimensionless governing transport equations along the boundary restrictions are resolved numerically with the help of NDsolve in Mathematica package. Impact of involved sundry parameters on the non-dimensional axial velocity, fluid temperature and concentration characteristics have been analyzed via plots and tables. It is manifest that an increasing porosity parameter leads to maximum velocity in the core part of the channel. Fluid velocity boosts near the walls of the channel where as the reverse effect in the central part of the channel for higher values of first order slip. Larger values of thermal radiation parameter R reduce the fluid temperature field. Also, an increase in heterogeneous reaction parameter Ks magnifies the concentration profile. The present study has the crucial application of thermal therapy in biomedical engineering.

In the new century the growth of population and an increasing of energy demands together with the difficulties of fossil fuel supply are expected. It is important to find optimal ways in solving such problems without the climate warming. The nuclear power having many advantages in comparison with fossil fuel technologies could play the great role in near future. The Medium-Sized Nuclear Reactors for production of electricity, heat and fresh water are considered as a main direction of nuclear power applications in the developing world It is important to discuss the requirements to such nuclear plants for using in the Countries with Small and Medium Electricity Grids. Particularly, cost-benefit analysis of construction NPP has to include assessment of all type risks and effectiveness of plant. In the paper an attention is paid on Water Reactors designed on the basis of navy technology. Such compact PWR built on special mills and placed on special floating vessel could be used in undeveloped regions. Total plant can be transported to any point of World Ocean and return back to mill for repair or decommissioning after exhaustion of lifetime. It is expected that such reactors with innovative design approach, provision of high safety and proper economic efficiency, based on leasing procedures, could be very attractive for medium-sized and developing countries.(author)

2011-08-01

During the last years there has been a growing need of developing innovative tools that can help small to medium sized enterprises to predict business failure as well as financial crisis. In this study we present a novel hybrid intelligent system aimed at monitoring the modus operandi of the companies and predicting possible failures. This system is implemented by means of a neural-based multi-agent system that models the different actors of the companies as agents. The core of the multi-agent system is a type of agent that incorporates a case-based reasoning system and automates the business control process and failure prediction. The stages of the case-based reasoning system are implemented by means of web services: the retrieval stage uses an innovative weighted voting summarization of self-organizing maps ensembles-based method and the reuse stage is implemented by means of a radial basis function neural network. An initial prototype was developed and the results obtained related to small and medium enterprises in a real scenario are presented.

Full Text Available This paper explores how small and medium enterprises (SMEs operating in Northern Italy and Slovenia used their innovative potential to expan business across the border while their home markets suffered from the great recession that started in 2007.  The background of the study is an analysis of the antecedents to export performance and internationlization, which specifically asked whether innovating incrementally or innovating radically contributes to export performance in foreign markets and how this ultimately interacts with strategic considerations and the propensity to take risks.  The findings of the study showed that export performance is positively influenced by incremental innovation and risk preference and that there is a relationship between innovation and export performance.  These findings contribute to the question whether classical internationalization theories such as the Uppsala Internationalization Model and the Innovation-related Model, can be applied in contingency situations of economic crisis.

Full Text Available The private sector, dominated by small and medium enterprises (SME, has been rapidly developing in Poland. Small and medium enterprises are defined as economic entities hiring not more than 250 employees and have turnovers lower than 50 million euros per year. The functioning of small and medium enterprises supports a decrease in unemployment, contributes to introduction of innovative operations and products as well as significantly influences GDP generation. The SME sector faces many barriers limiting their development. They include mainly social, financial and law barriers. Operations of the Polish Agency for Enterprise Development, Academic Business Incubators and other entities support small entrepreneurship. Recently, marketing in small and medium enterprises has particularly influenced their survival. A marketing programme consists of four elements a product, price, distribution, and promotion and is described as the marketing mix. In the paper, results of research in randomly selected enterprises of the SME sector are presented. The aim of the research was to diagnose a range of marketing operations’ use in these companies. The conducted research displays that marketing activity is used mainly for promotion in the investigated enterprises and to a small extent for managing a product’s portfolio in a firm.

2004-01-01

Full Text Available The kinetics of oxidation of some amino acids namely, glycine, alanine, aspartic acid, arginine, and histidine, (AA by N-chlorosaccharin (NCSA in aqueous acetic acid medium in the presence of perchloric acid have been investigated. The observed rate of oxidation is first order in [AA], [NCSA] and of inverse fractional order in [H+]. The main product of the oxidation is the corresponding aldehyde. The ionic strength on the reaction rate has no significant effect. The effect of changing the dielectric constant of the medium on the rate indicates the reaction to be of dipole-dipole type. Hypochlorous acid has been postulated as the reactive oxidizing species. The reaction constants involved in the mechanism are derived. The activation parameters are computed with respect to slow step of the mechanism.

2017-06-01

This is one of the first studies to examine the educational entrepreneur in K-12 public schools and the first to present an instrument designed to measure entrepreneurial thinking among teachers using a type of reasoning, effectual reasoning, which has been proposed in the business literature on entrepreneurs. This study situates entrepreneurial thinking within the K-12 education arena and examines the relationship between high school and middle school teachers' use of effectual reasoning and their corresponding implementation of high, medium, or low levels of innovation in STEM areas within their classrooms, districts, or across districts. Our findings correlated higher use of effectual reasoning, a component of entrepreneurial thinking, with higher levels of implementation of innovations among teachers within an NSF grant, Entrepreneurial Leadership in STEM Teaching and learning, which centered on deeper content, reform-oriented pedagogies, and entrepreneurial thinking. We found that high innovators viewed uncertainty' differently than low innovators by associating it with more positive cognitive structures and that innovators at different levels hold distinct notions of what constitutes high and low risk innovations. Contrary to the common notion that entrepreneurs are high-risk takers, results reveal that the types of innovations perceived by high innovators as low risk are viewed as high risk by low innovators. Furthermore, the results are consistent with the idea that entrepreneurs do certain types of things to lower/manage the risk of innovations before and, if necessary, during the implementation of an innovation.

We report the synthesis of graphene via the electrochemical reduction of graphene oxide (GO). In this study, GO nanosheets from aqueous dispersion were pre-assembled on a glassy carbon (GC) electrode and then electrochemically reduced in 1 M KOH under various constant reduction potentials in the range of −0.6 V to −1.5 V (vs. Ag/AgCl). X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy analyses revealed that the graphitic structure was substantially restored in the resulting electrochemically reduced graphene oxide (ERGO). The ERGO electrodes exhibited significantly enhanced catalytic activity toward the oxygen reduction reaction (ORR) in an alkaline medium compared with the initial GO electrode. Of the ERGO electrodes produced at various cathodic potentials, the ERGO-1.2 V electrode, which was produced at a reduction potential of −1.2 V, demonstrated the best catalytic activity toward the ORR in an alkaline medium. The ORR on GO and ERGO electrodes was shown to proceed via a two-electron mechanism at low overpotentials. The agreement between the spectroscopy results and electrochemical measurements provide strong evidence that the enhanced ORR catalytic activity is mainly attributed to the restoration of GO’s graphitic structure. Furthermore, the ERGO-1.2 V electrode showed excellent tolerance to the methanol poisoning effect compared with a Pt/C catalyst electrode.

The radioisotopes of indium, cadmium and tin have many practical and medical applications. Their standard routes for production are proton or deuteron induced reactions on natural or enriched cadmium or tin. The production via 3 He induced reactions on natural or enriched cadmium was rarely discussed. In this study 3 He induced reactions on natural cadmium were measured utilizing the stacked-foil technique. The primary incident beam energy was 27 MeV extracted from the MGC- 20E cyclotron, Debrecen, Hungary.the exciatation functions for the reactions n atCd( 3 He,x) 115g,111m Cd, 117m,g,116m,115m,114m,113m,111g,110m,g,109g,108g,107g In and 117m,113,111,110 Sn were evaluated. The data were compared with the available literature data.Different theoretical nuclear reaction models were also used to predict the cross sections for those reactions. The used models were ALICE-IPPE, TALYS-1.2 and EMPIRE-03. The experimental data were compared also to the theoretical model calculations. The theoretical models did not describe most of the experimental results.The isomeric cross section ratios for the isomeric pairs 117m,g In and 110m,g In were calculated. The isomeric cross section ratio depends on the spins of the states of the interested isomeric pair. The calculated isomeric ratios helped to identify the mechanisms of the reactions involved.The integral yields for some medically relevant isotopes were calculated using the excitation function curves

Maxim SANDU

2017-06-01

Full Text Available In modern conditions of development of the competitive environment, one of the main ways to solve economic, social and environmental problems is to use the latest achievements of science and technology. Each enterprise seeks to ensure that economic growth is intense, i.e. to be a consequence of the application of more sophisticated factors of production and technology. The prerequisite for intensive growth is the use of innovative strategy in the practical activities of enterprises. The end result of innovations is the materialization and industrial development of innovation, the idea of which can be the scientific and technical activity, and marketing research to identify unmet needs. The innovations are an effective defensive reaction of the firm to the emerging threats of losing market place, constant pressure from competitors, the challenge of new technologies, shortening the life of products, legislative restrictions and changing the market situation. In the offensive version, the innovation is a mean of exploiting new opportunities to preserve or gain a competitive advantage. In the long term aspect, the company has no choice but to pursue an innovation policy, which is the only source of lasting success. The main objective of researching the innovation activity of any organization is to ensure competitiveness in market conditions in order to identify risk factors and ways to overcome them.

2017-07-01

Full Text Available This study empirically explores the relationship between innovation performance and the internal and contextual factors driving technological innovation in manufacturing small and medium-sized enterprises (SMEs in metropolitan areas of Korea using structural equation modeling (SEM. Our analysis is based on firm-level data from the Korean Innovation Survey conducted by the Science and Technology Policy Institute in 2012. According to the results, SMEs’ innovation capacity was positively related to technological innovation performance, and SMEs’ skills and technology acquisition is a contextual factor that positively influences their innovation performance. In this process, SMEs’ innovation capacity is a partial mediator between skills and technology acquisition and SMEs’ technological innovation performance. Moreover, the results show that the relationship between government and public policies and SMEs’ innovation performance is mediated by SMEs’ internal innovation capacity. The results imply that both skills and technology acquisition and government and public policies are important contextual factors can increase SMEs’ innovation performance. Based on the results, this study provides implications for policy makers in terms of the policies that provide both direct and support roles in fostering and sustaining innovation, which drives regional economic growth and development.

A clear vision for vaccines research and development (R&D) is needed if Europe is to continue to lead the discovery of next generation vaccines. Innovation Partnership for a Roadmap on Vaccines in Europe (IPROVE) is a collaboration between leading vaccine experts to develop a roadmap setting out how Europe can best invest in the science and technology essential for vaccines innovation. This FP7 project, started in December 2013, brought together more than 130 key public and private stakeholders from academia, public health institutes, regulators, industry and small and medium-sized enterprises to determine and prioritise the gaps and challenges to be addressed to bolster innovation in vaccines and vaccination in Europe. The IPROVE consultation process was structured around seven themes: vaccine R&D, manufacturing and quality control, infrastructure, therapeutic vaccines, needs of small and medium-sized enterprises, vaccines acceptance and training needs. More than 80 recommendations were made by the consultation groups, mainly focused on the need for a multidisciplinary research approach to stimulate innovation, accelerated translation of scientific knowledge into technological innovation, and fostering of real collaboration within the European vaccine ecosystem. The consultation also reinforced the fact that vaccines are only as good as their vaccine implementation programmes, and that more must be done to understand and address vaccination hesitancy of both the general public and healthcare professionals. Bringing together a wide range of stakeholders to work on the IPROVE roadmap has increased mutual understanding of their different perspectives, needs and priorities. IPROVE is a first attempt to develop such a comprehensive view of the vaccine sector. This prioritisation effort, aims to help policy-makers and funders identify those vaccine-related areas and technologies where key investment is needed for short and medium-long term success.

CH(+) Destruction by Reaction with H: Computing Quantum Rates To Model Different Molecular Regions in the Interstellar Medium.

Science.gov (United States)

Bovino, S; Grassi, T; Gianturco, F A

2015-12-17

A detailed analysis of an ionic reaction that plays a crucial role in the carbon chemistry of the interstellar medium (ISM) is carried out by computing ab initio reactive cross sections with a quantum method and by further obtaining the corresponding CH(+) destruction rates over a range of temperatures that shows good overall agreement with existing experiments. The differences found between all existing calculations and the very-low-T experiments are discussed and explored via a simple numerical model that links these cross section reductions to collinear approaches where nonadiabatic crossing is expected to dominate. The new rates are further linked to a complex chemical network that models the evolution of the CH(+) abundance in the photodissociation region (PDR) and molecular cloud (MC) environments of the ISM. The abundances of CH(+) are given by numerical solutions of a large set of coupled, first-order kinetics equations that employs our new chemical package krome. The analysis that we carry out reveals that the important region for CH(+) destruction is that above 100 K, hence showing that, at least for this reaction, the differences with the existing laboratory low-T experiments are of essentially no importance within the astrochemical environments discussed here because, at those temperatures, other chemical processes involving the title molecule are taking over. A detailed analysis of the chemical network involving CH(+) also shows that a slight decrease in the initial oxygen abundance might lead to higher CH(+) abundances because the main chemical carbon ion destruction channel is reduced in efficiency. This might provide an alternative chemical route to understand the reason why general astrochemical models fail when the observed CH(+) abundances are matched with the outcomes of their calculations.

Technological know how and innovations will be of considerable future importance for West German industry. Changes in the reliability of sources of supply (energy, raw materials), the burden imposed on the environment by intensive industrial production and numerous private sources, and the stiffening of international competition necessitate cLoser collaboration between industry and government. Public aid in research and development efforts will assume an important role. In West Germany there is a wide variety of such governmental aids. The range extends from direct grants to enterprises for research and development work to the furnishing of advice to promote innovative efforts and technology transfer. Banks provide risk capital with governmental aid to firms trying to indroduce high-risk innovations into the market. In recent years the aim has been to provide small and medium-size firms with better access to technological know how and governmental aids.

De Lacy Costello, Benjamin; Adamatzky, Andrew

2005-01-01

We experimentally demonstrate that excitation wave-fragments in a Belousov-Zhabotinsky (BZ) medium with immobilised catalyst can be used to build elementary logical gates and circuits. Following our previous theoretical constructions [Adamatzky A. Collision-based computing in Belousov Zhabotinsky medium. Chaos, Solitons and Fractals 2004;21:1259-64] on embedding logical schemes in BZ medium, we represent True/False values of logical variables by presence/absence of wave-fragments. We show that when wave-fragments collide with each other they may annihilate, fuse, split and change their velocity vectors. Thus the values of logical variables represented by the wave-fragments change and certain logical operations are implemented. In the paper we provide examples of experimental logical gates, and present pioneer results in dynamic, architectureless computing in excitable reaction-diffusion systems

Medical innovation laws: an unnecessary innovation.

Richards, Bernadette

2016-06-01

Objective This paper aims to demonstrate that any suggestion that there is a need for specific innovation laws is flawed. Innovation is central to good medical practice and is adequately supported by current law. Methods The paper reviews the nature of medical innovation and outlines recent attempts in the UK to introduce specific laws aimed at 'encouraging' and 'supporting' innovation. The current legal framework is outlined and the role of the law in relation to medical innovation explored. Results The analysis demonstrates the cyclic relationship between medical advancement and the law and concludes that there is no requirement for specific innovation laws. Conclusions The law not only supports innovation and development in medical treatment but encourages it as central to a functioning medical system. There is no need to introduce specific laws aimed at medical innovation; to do so represents an unnecessary legal innovation and serves to complicate matters. What is known about the topic? Over recent months, there has been a great deal of discussion surrounding the law in the context of medical innovation. This was driven by the attempts in the UK to introduce specific laws in the Medical Innovation Bill. The general subject matter - negligence and the expected standard of care in the provision of treatment - is very well understood, but not in cases where the treatment can be described as innovative. The general rhetoric in both the UK and Australia around the Medical Innovation Bill demonstrates a lack of understanding of the position of the law with regards to innovative treatment. What does this paper add? This paper adds clarity to the debate. It presents the law and explains the manner in which the law can operate around innovative treatment. The paper asserts that medical innovation is both supported and encouraged by existing legal principles. What are the implications for practitioners? The paper presents an argument that can guide the policy position

1987-10-01

This document describes an initial step towards the formation of a computerized on-line data library, which would contain published medium-energy experimental data, and which would serve the basic and applied needs of the medium-energy nuclear physics community. The data emphasized in this project will be from measured charged-particle and meson induced nuclear scattering and reactions; an area for which no such data base presently exists. Access to the data will be through a menu-driven program in a user-friendly environment. The project is divided into three phases: Phase 1 involves compilation of Clinton P. Anderson Meson Physics Facility (LAMPF) data from nucleon and pion induced reactions, Phase 2 includes nucleon and pion data from other medium-energy facilities, and Phase 3 includes electron, light-ion, and possibly kaon and anti-nucleon data. The initial goals, the manner in which they would be pursued, and the resources needed to implement Phase 1 (the pilot phase) are discussed in detail. Possible expansion of Phase 1 to attain the envisioned goals of Phase 2 and 3 are briefly outlined. During all stages of the project, input from the community will be sought via the various facility user groups and the American Physical Society Division of Nuclear Physics. It is proposed that the Applied Nuclear Science Group (T-2) of the Los Alamos National Laboratory oversees the development and implementation of this project, and the LAMPF VAX computers be used as the host computers for on-line access

Industrialized Innovation: The Connection of Science & Technology Innovation with Industrial Innovation

Yinxing Hong; Yao Lu; Jianghuai Zheng

2017-01-01

In light of the relationship and the current disconnection between science & technology (S&T) innovation and industrial innovation in China,it is necessary to put forward and emphasize the concept of industrialized innovation.Industrialized innovation is the bridge and intermediation between S&T innovation and industrial innovation,which is not only a concept,but also a mechanism and combination force.There are two ways to achieve industrialized innovation:through industry-university-research coordination and through technology entrepreneurship.The meaning of industry-university-research coordination is not about coordination among industry,university and research sectors in an institutional sense;rather it is about the coordination of the functions of cultivation and development in new industries,new technologies,and new talents of industrialized innovation.The incentive mechanism for industrialized innovation should motivate not only innovation but also coordination.Technology entrepreneurship is the industrialization of new technology through business start-ups,which occurs beyond the stage of incubation and development of new technology.The capital of technology entrepreneurship is the set consisting of knowledge capital manifested through technological innovation,human capital manifested through entrepreneurs,and physical capital in the form of venture capital.While physical capital is indispensable,knowledge capital and human capital play the decisive role in technology entrepreneurship.The industrialization of technological innovation involves two requirements:one is to enable the new technology industry to achieve a large scale rapidly,and the other is to fully realize the potential value of the new technology.Both requirements are reliant on effective innovation in business models.

Organizational liability for adverse reactions to the contrast media

International Nuclear Information System (INIS)

Lim, Chang Seon

2007-01-01

Contrast medium is a very useful tool for X-ray examinations. But contrast medium has some unavoidable adverse reactions. For those patients who have never received contrast medium before, it is impossible to predict whether they will suffer from certain kinds of adverse reactions. Thus, radiologists should use strategies to minimize adverse events and be prepared to promptly recognize and manage any reactions to the contrast media. If a radiologist commits medical malpractice, he will face civil responsibility. Medical malpractice means a tort or breach of contrast that occurs in a medical setting. Medical malpractices happen, despite the efforts of hospital staff. Many courts have applied the traditional doctrine of respondeat superior in actions against organizations for injuries caused by their employees. It is a legal doctrine, which states that an employer is responsible for employee actions performed within the course of the employment. A hospital is an organization for health purposes. An organization may be convicted of an offense committed by an employee of the organization acting in its behalf and within the scope of this office or employment. Organizational liability involves a wide variety of legal issues, including tort liability, wrongful employment practices, personal injury, breach of fiduciary duty, and so on. Many executive directors of organizations are aware of their personal and organizational risks of exposure to legal liabilities. The employer must have the right to control the physical conduct of the employee and must consent to receive the employee's services, while expecting some benefits from the services offered. Therefore, legal liability can be imposed for improper selection, assignment, training, and supervision of employees. In conclusion, the hospital itself has organizational liability for adverse reactions to the contrast medium

Due to complex kinetics of formation and loss mechanisms, such as ion-ion recombination reaction, neutral species harpoon reaction, excited state quenching and photon absorption, as well as their interactions, the performance behavior of different laser gas medium parameters for excimer laser varies greatly. Therefore, the effects of gas composition and total gas pressure on excimer laser performance attract continual research studies. In this work, orthogonal experimental design (OED) is used to investigate quantitative and qualitative correlations between output laser energy characteristics and gas medium parameters for an ArF excimer laser with plano-plano optical resonator operation. Optimized output laser energy with good pulse to pulse stability can be obtained effectively by proper selection of the gas medium parameters, which makes the most of the ArF excimer laser device. Simple and efficient method for gas medium optimization is proposed and demonstrated experimentally, which provides a global and systematic solution. By detailed statistical analysis, the significance sequence of relevant parameter factors and the optimized composition for gas medium parameters are obtained. Compared with conventional route of varying single gas parameter factor sequentially, this paper presents a more comprehensive way of considering multivariables simultaneously, which seems promising in striking an appropriate balance among various complicated parameters for power scaling study of an excimer laser.

The research manifested that the companies focused markedly on innovations in supplying products on offer with additional functions or features. The research results show that the companies do not conduct changes in production organization frequently, not even following their earlier innovative activities. The results of the research into the innovative activity “change in product design” imply that this activity is not applied frequently in comparison with the above-mentioned activities. Based on the interviewed companies' weak points in human resources, the elementary drawbacks include lack of management's command of foreign languages as well as production staff's expert skills. The results of the research imply that the interviewed companies perceive the sphere of products (improved product quality, extension of a product range, the sphere of new technologies and the sphere of an increase in market potential as the most significant. The questionnaire inquiry shows that innovative and development activities are most frequently financed from companies' own funds, subsidies/grants, bank credits and leases. Mortgages and venture capital are only made used of occasionally.

Highlights: • Potential utilization of biomass waste generated from bioethanol production. • Enhanced generation of syngas from pyrolysis of oak tree waste by using CO 2 . • Reduction of tar formation in pyrolysis of oak tree waste. • Modification of morphology of oak tree waste biochar by using CO 2 in pyrolysis. - Abstract: In this study, the production of bioethanol was evaluated through a series of saccharification and fermentation of lignocellulosic biomass (e.g., oak tree) pre-treated with H 2 SO 4 , NH 3 , or NaOH using a yeast (Pichia stipitis). In addition, it was investigated the effects of CO 2 on pyrolysis of the biomass wastes remaining after saccharification of the three pre-treated oak tree (BWs: BW-H 2 SO 4 , BW-NH 3 , and BW-NaOH). Thus, this work emphasizes the mechanistic understanding of CO 2 in pyrolysis of BWs. The effect of CO 2 was most noticeable in syngas, as the ratio of CO and H 2 exhibited a 20 to 30-fold increase at >550 °C. The CO/H 2 ratio of pyrolysis of the waste in CO 2 is ∼1100% of that of pyrolysis of the waste in N 2 at 720 °C. Such proliferation of syngas led to the subsequent reduction of tar since the substantial amount of tar was consumed as a precursor of syngas: CO 2 not only expedited the thermal cracking of volatile organic compounds (VOCs), but also reacted with those VOCs. The morphologic modification of biochars also occurred in the presence of CO 2 via heterogeneous reaction between CO 2 and surface of BWs. In summary, this study shows a utilization of an oak tree waste generated from saccharification for bioethanol production as a pyrolysis feedstock to recover energy (i.e., syngas production). The use of CO 2 as pyrolysis medium not only enhanced syngas production from oak tree waste but also reduced tar formation by thermal decomposition of VOCs and reaction between VOCs and CO 2 . The process shown in this study can be used as a potential high energy recovery from a biomass waste by utilizing potent

Spectroscopic research of Lambda hypernuclei up to medium-heavy mass region with the (e,e'K⁺) reaction

Gogami, Toshiyuki [Tohoku Univ., Sendai (Japan)

2014-06-01

In 2009 (August-November), the E05-115 experiment was carried out at JLab to investigate L hypernuclei in the wide mass region up to A = 52 ($7\\atop{Λ}$He, $10\\atop{Λ}$Be, $12\\atop{Λ}$B and $52\\atop{Λ}$V) with the (e,e'K⁺) reaction. This is the first attempt to investigate a medium heavy L hypernucleus with the (e,e'K⁺) reaction. Experimentally, it is difficult to measure heavier L hypernuclei as background rates of particles which originate from electromagnetic processes are roughly in proportion to Z2 (Z: target proton number) in the (e,e'K⁺) experiment. To perform the experiment, many experimental techniques have been developed and introduced such as optimization of the electron spectrometer configuration (tilt method), clean kaon identification, particle tracking under high multiplicity environment, precise energy scale calibration and so on. In the present thesis, experimental results of the elementary process of p(e,e'K⁺)L, L hypernuclei of $7\\atop{Λ}$He, $10\\atop{Λ}$Be, $12\\atop{Λ}$B and $52\\atop{Λ}$V are shown. Elementary processes of the electroproduction of L and Σ⁰, p(e,e'K⁺)L, Σ⁰ were used for the absolute energy scale calibration of our spectrometer systems. A careful Monte Carlo simulation shows that the binding energy can be obtained with a systematic error of 0.11 MeV with our energy scale calibration method. A study of the elementary process of L is important to understand L hypernuclei as it is essential for theoretical calculations of L hypernuclei. The differential cross section of the p(e,e'K⁺)L reaction at the small K⁺ scattering angle (theta-CM/gamma-K approx. 15.5°), the small Q² (approx 0.01 [GeV/c]²) and the total energy of W = 1.92 GeV, where no experimental data exists was obtained to be 235 ± 13$+28\\atop{-24}$ nb/sr. The ground state (1/2⁺) binding energy

The chemiluminescence (CL) emission, observed when rhodamine B (RB) in 1-hexanol-cyclohexane was mixed with cerium(IV) sulfate in sulfuric acid dispersed in a reversed micellar medium of cetyltrimethylammonium chloride (CTAC) in 1-hexanol-cyclohexane/water, was investigated using a flow-injection system. The CL emission from the oxidation reaction of RB with Ce(IV) was found to be stronger in the CTAC reversed micellar solution compared with an aqueous solution. Bearing on the enhancement effect of the CTAC reverse micelles on the RB-Ce(IV) CL, several studies including stopped-flow, fluorescence and electron spin resonance (ESR) spectrometries were performed. Rapid spectral changes of an intermediate in the RB-Ce(IV) reaction in the aqueous and reversed micellar solutions were successfully observed using a stopped-flow method. The effect of the experimental variables, i.e., oxidant concentration, sulfuric acid concentration, the mole fraction of 1-hexanol, water-to-surfactant molar concentration ratio, flow rate, upon the CL intensity was evaluated. Under the experimental conditions optimized for a flow-injection determination of RB based on the new reversed micellar-mediated CL reaction with Ce(IV), a detection limit of 0.08 µmol dm(-3) RB was achieved, and a linear calibration graph was obtained with a dynamic range from 0.5 to 20 µmol dm(-3). The relative standard deviation (n = 6) obtained at an RB concentration of 3 µmol dm(-3) was 3%.

Impact of the in-medium nucleon-nucleon cross section on early-reaction-phase dynamics below 100 MeV/u

Basrak, Z.; Zoric, M.; Eudes, P.; Sebille, F.

It has been shown theoretically [1] and confirmed experimentally [2] that heavy ion reactions (HIR) at intermediate energies, especially for central collisions, are strongly dominated by the mid-rapidity emission, a component which is emitted early during the dynamical reaction phase. This prompt and copious dynamical emission is proportional to the impact parameter 6 and evacuates a large amount of available system energy [1,3]. Since this emission occurs in the early compact phase of HIR, it is crucial to study details of the early transformation of the initial relative motion of the entrance reaction channel into other forms of energy in particular to its main components, heat E th and compression E compr . We have carried out such a study within the framework of the semi-classical Landau-Vlasov model with the momentum-dependent Gogny interaction D1-G1 [4]. In this model, σ NN is the free nucleon-nucleon cross section with its usual energy and isospin dependence. For the sake of simplicity, σ NN is assumed to be isotropic and density independent, an approximation which is fully justified in HIR below 100 MeV/u. In an earlier work the free nucleon-nucleon cross section was considered [5]. Here, we investigate the in-medium effects, i.e. how the change of σ NN influences the early energy transformation and the early particle emission. The change is taken into account by multiplying σ NN by a corrective constant factor F. In other words, we examine how the E th and E compr evolve with the reaction time and how the dynamical emission behaves and both as a function of the factor F. We investigate two systems: 3 6A r + 6 8N i and 6 8N i + 6 8N i reactions at 52, 74, and 95 MeV/u (52, 74, and 90 MeV/u for the latter reaction) at all impact parameters from central to peripheral collisions. The results of the simulations show that the time evolution of heat E th and compression E compr during the early dynamical reaction phase present maxima at all incident energies

Where are All the Female Innovators? Nurses as Innovators in a Public Sector Innovation

Directory of Open Access Journals (Sweden)

Johanna Nählinder

2010-03-01

Full Text Available The field of innovation does not see the innovator and is therefore gender-blind. Still, there is an implicit understanding of who is innovative, and this understanding includes gender and profession of the innovator. The female nurse is not seen as innovative and few innovation policies target her. The lack of innovativeness is due to many factors and two of these are tested empirically in this article: that women work in professions which are not associated with innovation and that women lack confidence to carry out innovative work. The empirical investigation presents evidence in line with both hypothesis and also notes that men and women ends their innovative efforts for different reasons. Therefore, innovation policy targeting these groups mobilises otherwise dormant potential innovators.

Energy conservation techniques as innovations, and their diffusion

Energy Technology Data Exchange (ETDEWEB)

Darley, J M

1978-04-01

Many effective products, procedures, and techniques for achieving energy conservation have been discovered by researchers. This paper focuses on the conditions under which these procedures and techniques will be adopted voluntarily. It is suggested, first, that an economic incentive for the utilization of those energy-conserving techniques is not a sufficient condition for their adoption, and second, that a psychologically-based theory of the diffusion of innovation will identify the critical variables for promoting the adoption of energy-conserving products and techniques. Based on preliminary, small-scale observations of homeowners' reactions to a complex, time-controlled thermostat, the initial parameters of a diffusion theory for energy innovation are suggested.

Crossed molecular beam experiments of cyano radicals, CN(X2Σ+, ν=0), in their electronic and vibrational ground state reacting with unsaturated hydrocarbons acetylene, C2H2(X1Σ+g), ethylene, C2H4(X1Ag), methylacetylene, CH3CCH(X1A1), allene, H2CCCH2(X1A1), dimethylacetylene, CH3CCCH3(X1A1'), and benzene, C6H6 (X1A1g), were performed at relative collision energies between 13.3 and 36.4 kJ mol-1 to unravel the formation of unsaturated nitriles in the outflows of late-type AGB carbon stars and molecular clouds. In all reactions, the CN radical was found to attack the π electron density of the hydrocarbon molecule with the radical center located at the carbon atom; the formation of an initial addition complex is a prevalent pathway on all the involved potential energy surfaces. A subsequent carbon-hydrogen bond rupture yields the nitriles cyanoacetylene, HCCCN (X1Σ+), vinylcyanide, C2H3CN (X1A'), 1-methylcyanoacetylene, CH3CCCN (X1A1), cyanoallene, H2CCCH(CN) (X1A'), 3-methylcyanoacetylene, HCCCH2CN(X1A'), 1,1-cyanomethylallene, H2CCC(CN)(CH3) (X1A'), and cyanobenzene, C6H5CN (X1A1). In case of acetylene and ethylene, a second reaction channel involves a [1, 2]-H atom shift in the initial HCCHCN and H2CCH2CN collision complexes prior to a hydrogen atom release to form cyanoacetylene, HCCCN (X1Σ+), and vinylcyanide, C2H3CN (X1A'). Since all these radical-neutral reactions show no entrance barriers, have exit barriers well below the energy of the reactant molecules, and are exothermic, the explicit identification of this CN versus H atom exchange pathway under single collision conditions makes this reaction class a compelling candidate to synthesize unsaturated nitriles in interstellar environments holding temperatures as low as 10 K. This general concept makes it even feasible to predict the formation of nitriles once the corresponding unsaturated hydrocarbons are identified in the interstellar medium. Here HCCCN, C2H3CN, and CH3CCCN have been already observed

Dynamics of traveling reaction pulses

International Nuclear Information System (INIS)

Dovzhenko, A. Yu.; Rumanov, E. N.

2007-01-01

The growth of activator losses is accompanied by the decay of a traveling reaction pulse. In a ring reactor, this propagation threshold is present simultaneously with a threshold related to the ring diameter. The results of numerical experiments with pulses of an exothermal reaction reveal the transition from pulse propagation to a homogeneous hot regime, established regimes with periodic variations of the pulse velocity, and oscillatory decay of the pulse. When the medium becomes 'bistable' as a result of the variation in parameters, this factor does not prevent the propagation of pulses, but leads to changes in the pulse structure

2011-07-01

Full Text Available Innovations have become an increasingly important factor in the struggle to preserve and improve the competitive position of enterprises in domestic and international markets. Innovative companies are those that react to sudden changes in the environment but are also the very cause of change. Dynamic and turbulent changes in the environment and constantly increasing competition, among other factors, have affected the shortening product life cycle and the duration of innovative solutions. Starting from the model creation value, a company may decide to create a new model for value creation or create an imitation - an adaptation of a dominant model in the industry. Both extreme positions (innovator vs. follower require exceptional organizational skills. The aim of this paper is that, the life cycle of products and companies’ reactions to changes, determines whether the B&H companies are inventors or followers. In order to get a complete picture of the innovative strength of the observed B&H enterprises, we will, in addition, analyze the dynamics of investment in research and development, as well as top management’s view of the importance of innovation in achieving competitive advantages for their companies.

During processing and storage of industrial processed cheese, odorous compounds are formed. Some of them are potentially unwanted for the flavour of the product. To reduce the appearance of these compounds, a methodological approach was employed. It consists of: (i) the identification of the key compounds or precursors responsible for the off-flavour observed, (ii) the monitoring of these markers during the heat treatments applied to the cheese medium, (iii) the establishment of an observable reaction scheme adapted from a literature survey to the compounds identified in the heated cheese medium (iv) the multi-responses stoichiokinetic modelling of these reaction markers. Systematic two-dimensional gas chromatography time-of-flight mass spectrometry was used for the semi-quantitation of trace compounds. Precursors were quantitated by high-performance liquid chromatography. The experimental data obtained were fitted to the model with 14 elementary linked reactions forming a multi-response observable reaction scheme. Copyright © 2015 Elsevier Ltd. All rights reserved.

Motion to innovation: Brand value sources have (not changed over time

Kliestikova Jana

2017-01-01

Full Text Available Innovation drives the expansion of economies in a global dimension. This is also the reason why contemporary researches indicates the trend of incorporation of the innovation to the strategic concept of brand value building and managing. It has been proven, that innovation is relevant source of brand value perceived by consumers. Such a trend has been established in reaction to the growing importance of brand value for competitive advantage creation in a global perspective. Currently published scientific contributions mainly highlight the importance of brand innovation in selected sectors of national economies abstracting from innovation perceptions due to the national socio-psychological profile. This is the reason why universally applicable theory of innovation in scope of brand value building and managing is missing. The lack of the theory can be removed by identification of importance of innovation attributes as brand value sources in context of market specifics. So, the aim of this paper is to provide such an identification and to verify existence of divergences between “foreign” theory and “domestic” practice. To do that, we use questionnaire, selection analysis and cluster analysis. We detect specifics of brand value perception focusing on innovation and its attributes comparing theory and reality of Slovak environment.

This paper aims to disentangle the mechanisms through which technological similarity between acquiring and acquired firms influences innovation in horizontal acquisitions. We develop a theoretical model that links technological similarity to: (i) two key aspects of post-acquisition reorganization...... of acquired R&D operations – the rationalization of the R&D operations and the replacement of the R&D top manager, and (ii) two intermediate effects that are closely associated with the post-acquisition innovation performance of the combined firm – improvements in R&D productivity and disruptions in R......&D personnel. We rely on PLS techniques to test our theoretical model using detailed information on 31 horizontal acquisitions in high- and medium-tech industries. Our results indicate that in horizontal acquisitions, technological similarity negatively affects post-acquisition innovation performance...

Forms of Supporting Local Innovative Business Activity in European Countries

Directory of Open Access Journals (Sweden)

Oleksandr Fedirko

2017-04-01

Full Text Available The article investigates contemporary trends of innovation policy of European countries, describes the essence of contemporary mechanisms and tools for supporting local innovative development. The following most powerful tools for facilitating scientific and technical and innovative business activity are discovered: direct support of private R&D, financing of innovative enterprises, governmental and private cooperative scientific and research projects. A trend is identified for decreasing the share of institutional financing of R&D, and increasing of weight of competitive financing of academic institutions. A conclusion is made as for spreading of technologies commercialization processes support, especially on final stages thereof; the share of these has increased in respect of governmental programs focused on early stages of scientific and research projects. An insight is that within the last two decades the tools for facilitating local innovative business activities have been diversified in the EU: alongside with long-term collaborative governmental and private R&D and initiatives for developing innovative science intensive clusters, short-term tools have been significantly spread, such as innovation projects vouchers and science intensive start-ups support. Given that, it is established that traditionally developed toolkit for supporting small and medium enterprises is being complimented with scaled programs of large companies direct financing. A general trend is identified for increasing the weight of collaborative programs, while the share of individual subsidies and grants for R&D and that of companies innovative activity has substantially decreased. Higher effectiveness of start-ups facilitation measures is concluded, as well as that of venture investments, in comparison with individual subsidies. The leading role of start-ups in EU economy is determined by a range of advantages originating from dynamic process of formation thereof

Open Innovation at the Root of Entrepreneurial Strategy: A Case from the Norwegian Oil Industry

Directory of Open Access Journals (Sweden)

Tatiana Iakovleva

2013-04-01

Full Text Available This article aims to extend the discussion about entrepreneurial strategies of small and medium-sized enterprises (SMEs by including the concept of open innovation. How can SMEs overcome the challenges of resource scarcity and harsh competition? How they can gain competitive advantage in today’s ever-changing business environment? The answer to both of these questions might be through open innovation: collaborating with researchers, customers, suppliers – even competitors – as well as research institutions and universities. A common barrier to open innovation in an SME is the perception that it will be too time consuming to gain access to a knowledge base of external knowledge providers and link to “gatekeepers” of knowledge. However, an entrepreneurial mindset might help SMEs to move toward an open-innovation approach, where more codified and transferrable knowledge are important. This article discusses the implications of an entrepreneurial focus for open-innovation activities. The usefulness of the open-innovation principles are highlighted through a case study of an Norwegian SME operating in the maritime-oil industry.

Market Orientation and Sources of Knowledge to Innovate in SMEs: A Firm Level Study

Directory of Open Access Journals (Sweden)

Simone Regina Didonet

2016-10-01

Full Text Available This work examines the relationship between the three market orientation (MO components, i.e. customer orientation, competitor orientation and inter-functional coordination, and the extension to which small and medium-sized enterprises (SMEs use different sources of knowledge to innovate. Based on a sample of 181 Chilean SMEs, a confirmatory factorial analysis (CFA was performed to analyze the relationship among constructs. The results show that the extension to which SMEs use different sources of knowledge to innovate depends on the interactions between MO components. This study addresses a gap in the literature, by linking and interrelating market orientation components to the innovation perspective in SMEs. Therefore, we provide insights into the role of each MO component in influencing the extension to which firms seek for and use different sources of knowledge to innovate and attempt to explain some literature inconsistencies on the theme.

The Effects of Variable Viscosity, Viscous Dissipation and Chemical Reaction on Heat and Mass Transfer Flow of MHD Micropolar Fluid along a Permeable Stretching Sheet in a Non-Darcian Porous Medium

Directory of Open Access Journals (Sweden)

A. M. Salem

2013-01-01

Full Text Available A numerical model is developed to study the effects of temperature-dependent viscosity on heat and mass transfer flow of magnetohydrodynamic(MHD micropolar fluids with medium molecular weight along a permeable stretching surface embedded in a non-Darcian porous medium in the presence of viscous dissipation and chemical reaction. The governing boundary equations for momentum, angular momentum (microrotation, and energy and mass transfer are transformed to a set of nonlinear ordinary differential equations by using similarity solutions which are then solved numerically by shooting technique. A comparison between the analytical and the numerical solutions has been included. The effects of the various physical parameters entering into the problem on velocity, microrotation, temperature and concentration profiles are presented graphically. Finally, the effects of pertinent parameters on local skin-friction coefficient, local Nusselt number and local Sherwood number are also presented graphically. One important observation is that for some kinds of mixtures (e.g., H2, air with light and medium molecular weight, the magnetic field and temperature-dependent viscosity effects play a significant role and should be taken into consideration as well.

The free convection boundary layer flow with simultaneous heat and mass transfer in a porous medium is studied when the boundary wall moves in its own plane with suction. The study also incorporates chemical reaction for the very simple model of a binary reaction with Arrhenius activation energy. For large suction asymptotic approximate solutions are obtained for the flow variables for various values of the activation energy. (author). 10 refs, 2 figs

1992-01-01

Research in three principal areas is summarized: (1) Work in elementary hadron structure seeks to further the understanding of hadron structure within the framework of quantum chromodynamics (QCD) and QCD-based models. A comparative study of meson properties employed three relativistic models: an extended Dziembowski model, a generalized light-front approach, and a completely covariant null plane approach. (2) Work on the electromagnetic production of strangeness addressed systems involving the strange quark (hyperons) and hyperon electromagnetic production and radiative capture processes. (3) In the work on medium-energy photonuclear reactions, a large-scale continuum shell-model calculation was performed for (γ,N) and (N,γ) reactions at low and medium energies spanning the Δ isobar region

Full Text Available The small-and medium-sized enterprises in the Hungarian economy have been playing a decisive role. Among the difficulties they face during their activities one of the most serious is to raise funds for their labour costs. They try to reduce their tax wedge burden, which is regarded one of the highest in Europe, in various ways. In order to keep the adequate workforce they can provide fringe benefits supplementing to wages and salaries. The cautious application of the referring acts enables companies to motivate workforce and reduce the tax and contribution burdens at the same time. Our research aimed to find an answer how SMEs take these advantages and what factors support or hinder the use of the system.

Full Text Available Using a survey of 324 small and medium-sized enterprises (SMEs of the Yangtze River Delta in China, this study discusses the relationship between entrepreneurial orientation, absorptive capacity, environmental dynamism, and corporate technological innovation performance. The results based on a moderated moderation model show that the relationship between entrepreneurial orientation and innovation performance is significantly positive. The absorptive capacity can positively moderate this relationship. When the external environment is in high dynamism, the moderating effect of absorptive capacity will be stronger than when the environment is in low dynamism.

Cross-section calculations for neutron-induced reactions up to 50 MeV

International Nuclear Information System (INIS)

Yamamuro, Nobuhiro.

1996-01-01

In the field of accelerator development, medium-energy reaction cross-section data for structural materials of accelerator and shielding components are required, especially for radiation protection purposes. For a d + Li stripping reaction neutron source used in materials research, neutron reaction cross sections up to 50 MeV are necessary for the design study of neutron irradiation facilities. The current version of SINCROS-II is able to calculate neutron and proton-induced reaction cross sections up to ∼ 50 MeV with some modifications and extensions of the cross-section calculation code. The production of isotopes when structural materials and other materials are bombarded with neutrons or protons is calculated using a revised code in the SINCROS-II system. The parameters used in the cross-section calculations are mainly examined with proton-induced reactions because the experimental data for neutrons above 20 MeV are rare. The status of medium mass nuclide evaluations for aluminum, silicon, chromium, manganese, and copper is presented. These data are useful to estimate the radiation and transmutation of nuclei in the materials

Gas phase kinetics of the OH + CH3CH2OH reaction at temperatures of the interstellar medium (T = 21-107 K).

Ethanol, CH 3 CH 2 OH, has been unveiled in the interstellar medium (ISM) by radioastronomy and it is thought to be released into the gas phase after the warm-up phase of the grain surface, where it is formed. Once in the gas phase, it can be destroyed by different reactions with atomic and radical species, such as hydroxyl (OH) radicals. The knowledge of the rate coefficients of all these processes at temperatures of the ISM is essential in the accurate interpretation of the observed abundances. In this work, we have determined the rate coefficient for the reaction of OH with CH 3 CH 2 OH (k(T)) between 21 and 107 K by employing the pulsed and continuous CRESU (Cinétique de Réaction en Ecoulement Supersonique Uniforme, which means Reaction Kinetics in a Uniform Supersonic Flow) technique. The pulsed laser photolysis technique was used for generating OH radicals, whose time evolution was monitored by laser induced fluorescence. An increase of approximately 4 times was observed for k(21 K) with respect to k(107 K). With respect to k(300 K), the OH-reactivity at 21 K is enhanced by two orders of magnitude. The obtained T-expression in the investigated temperature range is k(T) = (2.1 ± 0.5) × 10 -11 (T/300 K) -(0.71±0.10) cm 3 molecule -1 s -1 . In addition, the pressure dependence of k(T) has been investigated at several temperatures between 21 K and 90 K. No pressure dependence of k(T) was observed in the investigated ranges. This may imply that this reaction is purely bimolecular or that the high-pressure limit is reached at the lowest total pressure experimentally accessible in our system. From our results, k(T) at usual IS temperatures (∼10-100 K) is confirmed to be very fast. Typical rate coefficients can be considered to range within about 4 × 10 -11 cm 3 molecule -1 s -1 at 100 K and around 1 × 10 -10 cm 3 molecule -1 s -1 at 20 K. The extrapolation of k at the lowest temperatures of the dense molecular clouds of ISM is also discussed in this paper.

A systematic study of reaction mechanisms at intermediate energies (50-100 MeV/A) has been performed at the Lawrence Berkeley Laboratory's BeValac using medium weight projectiles on medium and heavy element targets. A gas and plastic phoswich detector system was employed which gave large geometric coverage and a wide dynamic response. The particles identified with the gas detectors could be characterized into three components - intermediate mass fragments (IMF), fission fragments (FF) and heavy residues (HR). Major observed features are: The reaction yields are similar in the 50 to 100 MeV/A range, central collisions have high multiplicty of IMF's with broad angular correlations consistent with a large participant region, effects of final state Coulomb interactions are observed and give information on the size and temporal behavior of the source, true fission yields are dependent on target fissility and correlated with relatively peripheral collisions. Analysis of fission and evaporation yields implies limiting conditions for which fission decay remains a viable deexcitation channel. (orig.)

Full Text Available To survive and prosper, the organizations need to embed the processes and mechanisms to discover major technology and consumer trends and respond to them through new growth areas. Based on profound literature review providing insight into organizational factors that affect firms’ ability to manage innovation this paper asks which innovation processes and entrepreneurial culture support radical innovations. The aim of the paper is to specify the company behaviour that leads to innovative outputs with high level of novelty in country specific context of Slovakia. We conducted two-stage empirical research in 2009 and 2014 mapping companies’ approach to innovation management during the last 10 years. After surveying 102 firms in the first stage and 287 firms in the second stage we derive success factors for radical innovations. The findings demonstrate growing importance of corporate strategic orientation, highly developed innovation processes and parallel mechanisms for radical innovation, ability to manage internally and externally open innovation and support entrepreneurial culture. This study makes unique contribution to the understanding of innovation processes, organizational factors, and their significance and dynamics. It should attract managerial attention to recognize the importance of innovation management factors for building firm’s innovation competency.

Medium-energy charged-particle data for evaluation

Pearlstein, S.

1989-01-01

Medium-energy charged particles incident on targets can cause a variety of nuclear reactions. Charged-particle transport calculations require access to a large body of cross-section data, which results in interest in an evaluated charged-particle data library. Developing an evaluated data library can involve several steps. An index to the literature on measurements and theory is useful to locate information relevant to data evaluation. A computerized compilation of measurements facilitates the intercomparison of different experiments and the determination of how well data are known. Nuclear models, based on theory or phenomenological evidence, are compared with experiment and, where validated, are used to fill in regions where experimental data are not available. Finally, the selected data are placed into computer-readable formats for use in transport calculations. Specialized indexes to bibliography help the scientist to keep up with his field and catch up with new subjects of interest. Several indexes are relevant to medium-energy nuclear data. In addition, these data are covered in several reports not issued on a regular basis. The technical area of medium-energy charged-particle data is maturing. From isolated measurements and theories, a comprehensive approach toward establishing a validated data base extending from low to high energies is emerging

Full Text Available Kinetics of oxidation of 3,4,5-trimethoxybenzaldehyde (TMBA by pyridinium fluorochromate (PFC in N,N-dimethyl formamide (DMF medium in the presence of toluene para-sulfonic acid (TsOH has been studied. The reaction is first order each in [PFC], [TMBA] and [TsOH]. The rate of oxidation remains unaltered by the variation of NaClO4 but addition of MnSO4 decreases the rate. The effects of the dielectric constant of the medium and the ionic strength indicate the reaction to be of ion–dipole type. The stoichiometry of the reaction is 1:1 and the product of oxidation is the corresponding 3,4,5-trimethoxybenzoic acid and Cr(III. The reaction rates have been determined at different temperatures and the activation parameters were calculated. The reaction failed to induce the polymerization of acrylonitrile, i.e., absence of free radicals. A suitable mechanism involving the slow formation of an unstable chromate ester and a rate law has been proposed.

The International Reactor Innovative and Secure (IRIS) is being developed by an international consortium of industry, laboratory, university and utility establishments, led by Westinghouse. The IRIS design addresses key requirements associated with advanced reactors, including improved safety, enhanced proliferation resistance, competitive electricity production cost, and improved waste management. IRIS is a modular, small/medium size (335 MWe) PWR with an integral vessel configuration. The objective has been to base its design on proven LWR technology, so that no new technology development is needed and near-term deployment is possible, yet at the same time to introduce innovative features making it attractive when compared to present PWRs. These opposing requirements resulted in an evolutionary approach to fuel and core design, balancing new features against the need to avoid extensive testing and demonstration programmes. (author)

Full Text Available Small and medium enterprises (SME are the engine of the European economy. They are an essential source of jobs, create entrepreneurial spirit and innovation in the EU and are thus crucial for fostering competitiveness and employment. In the enlarged European Union of 27 countries, some 20 million SMEs provide around 75 million jobs and represent 99 % of all enterprises. However, they are often confronted with market imperfections. SMEs frequently have difficulties in obtaining capital or credit, particularly in the early start–up phase. Their limited resources may also restrict access to new technology or innovation. It is therefore necessary to monitor the development of SMEs in individual EU countries and highlighting their problems and mainly to their importance.During the recent period of time there have been many researchers from the FBE Mendel University in Brno, who focused on the analysis of the small and medium-sized enterprise, e.g. Bohušová (2007; Chládková (2009; Nerudová a Bohušová (2008; Kubíčková a Peprný (2006; Zrůst a Pyšný (2008.

2014-05-15

Although there are already some qualification offers available for enterprises to support resource efficiency innovations, the high potentials that can be identified especially for small and medium sized enterprises (SMEs) have not been activated until now. As successful change lies in the hands of humans, the main aim of vocational education has to be the promotion of organisational and cultural changes in the enterprises. As there is already a small but increasing number of enterprises that perform very well in resource efficiency innovations one question arises: What are typical characteristics of those enterprises? Leaning on a good-practice approach, the project "ResourceCulture" is going to prove or falsify the hypothesis that enterprises being successful with resource efficiency innovations have a specific culture of trust, which substantially contributes to innovation processes, or even initially enables them. Detailed empirical field research will light up which correlations between resource efficiency, innovation and cultures of trust can be found and will offer important aspects for the improvement of management instruments and qualification concepts for workplace training. The project seizes qualification needs that were likewise mentioned by enterprises and consultants, regarding the implementation of resource efficiency. This article - based on first empirical field research results - derives preliminary indications for the design of the qualification module for the target groups resource efficiency consultants and managers. On this basis and in order to implement "ResourceCulture" conceptual and methodological starting points for workplace training are outlined. Copyright © 2013 Elsevier B.V. All rights reserved.

Full Text Available Purpose: This article analyzes the factors that influence on the capacity of service firms companies to adapt to changing environment. It analyzes how the critical dimensions of the innovation process influence the gap generated by the difference between the current level of innovation of the company and the level developed by competitors. Design/methodology/approach: Companies were selected from the database Duns and Bradstreet 2000. A sample of companies in Spain in a relatively homogeneous geographic, cultural, legal and political space was chosen. The questionnaire was sent to a total of 200 companies, most of them being large and medium enterprises. Findings and Originality/value: The results show that customer involvement in the innovation process is greater in service firms that have greater innovation gap and are more proactive. Formalization and decentralization present low innovation gap. Limitations: This study is focused on Spanish companies. This work presents the characteristics of a cross-sectional study. Practical implications: In order to better adapt to the environment, firms need to present a greater fit between results on innovation and customer expectations. Therefore, it is very important to accurately detect user needs throughout the innovation process. Originality/value: Our results provide guidance in decisions that are deliberate and which may affect the degree of proactivity of innovation in services. We have advanced in the implications of customer participation in business results. Keywords: Innovation gap, customer participation, decentralization, formalization, service firms.

Ullah, Imran; Bhattacharyya, Krishnendu; Shafie, Sharidan; Khan, Ilyas

2016-01-01

Numerical results are presented for the effect of first order chemical reaction and thermal radiation on mixed convection flow of Casson fluid in the presence of magnetic field. The flow is generated due to unsteady nonlinearly stretching sheet placed inside a porous medium. Convective conditions on wall temperature and wall concentration are also employed in the investigation. The governing partial differential equations are converted to ordinary differential equations using suitable transformations and then solved numerically via Keller-box method. It is noticed that fluid velocity rises with increase in radiation parameter in the case of assisting flow and is opposite in the case of opposing fluid while radiation parameter has no effect on fluid velocity in the forced convection. It is also seen that fluid velocity and concentration enhances in the case of generative chemical reaction whereas both profiles reduces in the case of destructive chemical reaction. Further, increase in local unsteadiness parameter reduces fluid velocity, temperature and concentration. Over all the effects of physical parameters on fluid velocity, temperature and concentration distribution as well as on the wall shear stress, heat and mass transfer rates are discussed in detail.

Effect of Water Clustering on the Activity of Candida antarctica Lipase B in Organic Medium

Directory of Open Access Journals (Sweden)

Sindrila Dutta Banik

2017-07-01

Full Text Available The effect of initial water activity of MTBE (methyl tert-butyl ether medium on CALB (Candida antarctica lipase B catalyzed esterification reaction is investigated using experimental methods and classical molecular dynamics (MD simulations. The experimental kinetic studies show that the initial reaction rate of CALB-catalyzed esterification reaction between butyric acid and ethanol decreases with increasing initial water activity of the medium. The highest rate of esterification is observed at the lowest water activity studied. MD simulations were performed to gain a molecular insight on the effect of initial water activity on the rate of CALB-catalyzed reaction. Our results show that hydration has an insignificant effect on the structure and flexibility of CALB. Rather, it appears that water molecules bind to certain regions (“hot spots” on the CALB surface and form clusters. The size of the water clusters at these hot spot regions gradually increase and expand with increasing water activity. Consequently, the surface area of CALB covered by the water molecules also increases. Specifically, our results indicate that a particular water cluster located close to the active site partially cover the binding pocket of substrate at high water activity. As a consequence, the effective concentration of substrate at the catalytic site decreases. Therefore, the reaction rate slows down with increasing water activity, which correlates well with the observed decrease in the experimentally determined initial reaction rate.

The rate constants increase in concert with the reductant concentration but sharply decrease with increasing base concentration in the reaction medium. The principal factor affecting the rate of Pu(VII) reduction by alcohols is probably steric in nature. Secondary alcohols are more active in basic medium. The resulting experimental data also confirm the very strong oxidizing capability of Pu(VII), the rate of reduction of which by CH 3 OH or C 2 H 5 OH compared with Np(VII) under similar conditions is 20-50 times faster

Full Text Available The need to innovate is increasingly important for all types and sizes of organizations, but the opportunities for innovation differ substantially between them. For micro-, small,- and medium-sized enterprises, innovation activities are both crucial and demanding because of limited resources, competencies, or vision to innovate their offerings. To support these organizations, the concept of living labs as a service has started to emerge. This concept refers to living labs offering services such as designing the idea-generation processes, planning or carrying out real-world tests of innovations, and pre-market launch assessments. In this article, we will present the findings from a study of micro-enterprises operating in the information technology development sector, including the experienced value of services provided to the companies by a research-based living lab. We share experiences from Botnia, our own living lab in northern Sweden. In this living lab, our aim of creating value for customers is of key importance. Our study shows that using a living lab as a service can generate three different types of value: improved innovations, the role the living lab can play, and the support the living lab offers.

Charge correlations in the breakup of gold projectiles in reactions at E/A=600 MeV

International Nuclear Information System (INIS)

Kreutz, P.

1992-09-01

In the present thesis the charge correlations in the breakup of gold projectiles in heavy ion collisions at an incident energy of E/A=600 MeV were studied. Thereby it has been proved that the sum of the charges from the projectile source under exclusion of the protons (Z bound ) is saliently suited for the classification of the nuclear reactions. At large values of Z bound we fins fission and spallation reactions. For smaller values of Z bound we observe events with an increasing number of medium-heavy fragments. Thereby the multifragment events appear in the Dalitz diagrams as a continuation of more symmetric becoming spallation events. In reactions with Z bound ≅ 35 the conditions for the formation of medium-heavy fragments are optimal and the multifragment events represent the dominating exit channel. A mean multiplicity of the medium-heavy fragments of ≅ 4 is reached. (orig./HSI) [de

2012-01-01

Butacaine sulfate is an ester of p-aminobenzoic acid which has been widely used as a local anaesthetic and it is a long standing agent particularly for spinal anaesthesia. For this reason, a kinetic study of oxidation of butacaine sulfate by sodium N-chlorobenzenesulfonamide (chloramine-B or CAB) has been carried out in HClO 4 medium at 303 K in order to explore this redox system mechanistic chemistry. The rate shows a first-order dependence on both [CAB] o , and [substrate] o , and a fractional-order dependence on acid concentration. Decrease of dielectric constant of the medium, by adding methanol, increases the rate of the reaction. Variation of ionic strength and addition of benzenesulfonamide or NaCl have no significant effect on the rate. The reaction was studied at different temperatures and the activation parameters have been evaluated. The stoichiometry of the reaction has been found to be 1:2 and the oxidation products have been identified by spectral analysis. The observed results have been explained by plausible mechanism and the related rate law has been deduced

The aim of this study was to document, using consensus methodology, current practice for prevention of generalized reactions to contrast media, to identify areas where there is disagreement or confusion and to draw up guidelines for reducing the risk of generalized contrast media reactions based on the survey and a review of the literature. A document with 165 questions was mailed to 202 members of the European Society of Urogenital Radiology. The questions covered risk factors and prophylactic measures for generalized contrast media reactions. Sixty-eight members (34%) responded. The majority indicated that a history of moderate and severe reaction(s) to contrast media and asthma are important risk factors. The survey also indicated that patients with risk factors should receive non-ionic contrast media. In patients at high risk of reaction, if the examination is deemed absolutely necessary, a resuscitation team should be available at the time of the procedure. The majority (91%) used corticosteroid prophylaxis given at least 11 h before contrast medium to patients at increased risk of reaction. The frequency of the dosage varied from one to three times. Fifty-five percent also use antihistamine Hl, mainly administered orally and once. Antihistamine H2 and ephedrine are rarely used. All essential drugs are available on the emergency resuscitation trolley. Patients with risk factors are observed up to 30 min by 48% and up to 60 min by 43% of the responders. Prophylactic measures are not taken before extravascular use of contrast media. Prophylactic drugs are given to patients with a history of moderate or severe generalized reaction to contrast media. In patients with asthma, opinion is divided with only half of the responders giving prophylactic drugs. Aspirin, β-blockers, interleukin-2 and non-steroid anti-inflammatory drugs are not considered risk factors and therefore are not stopped before injection of contrast media.

Investigation of the direct and indirect electrochemical oxidation of hydrazine in nitric acid medium on platinum

International Nuclear Information System (INIS)

Cames, B.

1997-01-01

In nuclear fuel processing by the PUREX process, the purification of plutonium in nitric acid medium requires the oxidation of Pu(III) to Pu(IV), and of hydrazinium nitrate to nitrogen. The study helped to characterize the electrochemical behavior of the oxidation of hydrazinium nitrate and the reduction of nitric acid to nitrous acid, a compound which can chemically oxidize hydrazinium nitrate and Pu(III). Electro-analytical studies on polycrystalline platinum showed that hydrazine is oxidized in two potential zones, which depend on the surface texture of the platinum anode. Electrolysis in separate compartments, carried out in medium-acid media (2 and 4 mo/l) in the potential zone where these processes take place, showed that, at 0.9 V/ECS, the hydrazine oxidation reactions involved are: a four-electron process (75 %) with nitrogen formation and a one-electron process (25 %) with formation of nitrogen and ammonium ion. By contrast, electrolysis carried out at 0.65 V/ECS (with reactivation of the electrode at - 0.2 V/ECS to remove the poison from the platinum) allowed the selective oxidation of hydrazine to nitrogen by the four-electron reaction. Nitric acid can only be reduced to nitrous acid in the absence of hydrazine. For medium-acid media (≤ 6 mol/l), this reaction takes place at potentials below - 0.2 V/ECS. However, the production rate of nitrous acid (partial order 0 with respect to nitric acid) is very low compared with the values obtained for strongly-acid media (6 to 10 mol/l) at the potential of - 0.1 V/ECS. Note that, in concentrated nitric medium, the selectivity of the reduction reaction is 47 to 85 % for nitrous acid, depending on the nitric acid concentration (6 to 10 mol/l) and the potential imposed (- 0.1 ≤ E ≤ 0.6 V/ECS). A kinetic study helped to determine the hydrazine oxidation rates as a function of the operating conditions. In all cases, the reaction rate is of partial order 0 with respect to hydrazine. These studies accordingly

Gas phase kinetics of the OH + CH3CH2OH reaction at temperatures of the interstellar medium (T = 21-10^7 K)

Ocaña, A. J.; Blázquez, S.; Ballesteros, B.; Canosa, A.; Antiñolo, M.; Albaladejoab, J.; Jiménez, E.

Ethanol, CH3CH2OH, has been unveiled in the interstellar medium (ISM) by radioastronomy and it is thought to be released into the gas phase after the warm-up phase of the grain surface, where it is formed. Once in the gas phase, it can be destroyed by different reactions with atomic and radical species, such as hydroxyl (OH) radicals. The knowledge of the rate coefficients of all these processes at temperatures of the ISM is essential in the accurate interpretation of the observed abundances. In this work, we have determined the rate coefficient for the reaction of OH with CH3CH2OH (k(T)) between 21 and 10^7 K by employing the pulsed and continuous CRESU (Cinétique de Réaction en Ecoulement Supersonique Uniforme, which means Reaction Kinetics in a Uniform Supersonic Flow) technique. The pulsed laser photolysis technique was used for generating OH radicals, whose time evolution was monitored by laser induced fluorescence. An increase of approximately 4 times was observed for k(21 K) with respect to k(10^7 K). With respect to k(300 K), the OH-reactivity at 21 K is enhanced by two orders of magnitude. The obtained T-expression in the investigated temperature range is k(T) = (2.1 ± 0.5) × 10^-11 (T/300 K)-(0.71±0.10) cm^3 molecule^-1 s^-1. In addition, the pressure dependence of k(T) has been investigated at several temperatures between 21 K and 90 K. No pressure dependence of k(T) was observed in the investigated ranges. This may imply that this reaction is purely bimolecular or that the high-pressure limit is reached at the lowest total pressure experimentally accessible in our system. From our results, k(T) at usual IS temperatures (˜10-100 K) is confirmed to be very fast. Typical rate coefficients can be considered to range within about 4 × 10^-11 cm^3 molecule^-1 s^-1 at 100 K and around 1 × 10^-10 cm^3 molecule^-1 s^-1 at 20 K. The extrapolation of k at the lowest temperatures of the dense molecular clouds of ISM is also discussed in this paper.

Theoretical analysis of thermal molten metal-water reactions

Schwalbe, W.

1982-01-01

In experiments with greater masses (kg-scale) two extreme cases had been oberved during the course of reaction when hot melt reacted with a vaporizable cooler liquid. Relatively mild hot interactions with slow pressure build-up and small pressure peak in the reaction volume often occurred but there were also some very violent reactions (steam explosions) where a remarkable portion of thermal energy had been transformed into mechanical energy with high pressure peaks. For the two types of reactions overall models for water as a coolant are developed here. Based on calculations and on comparisons with corresponding experiments it is shown that a relatively mild course of reaction can be explained by a fragmentation of the melt under following violent evaporation of the cooling medium. Pressures only with small reaction volumes up to the MPa range can be found in these reactions. The calculations, for example of Bird and Millington, showed a pressure maximum of 1 MPa after 170 ms of the start of the reaction; this agrees very well with the result of the experiment of 1.08 MPa.

A dynamical model dedicated to nucleon induced reaction between 30-150 MeV is presented. It considers different stages of the reaction: the approaching phase, the in-medium nucleon-nucleon collisions, the cluster formation and the secondary de-excitation process. The notions of influence area and phase-space exploration during the reaction are introduced. The importance of the geometry of the reaction and of the conservation laws are underlined. The model is able to globally reproduce the absolute cross sections for the emission of neutron and light charged particles for proton and neutron induced reactions on heavy and intermediate mass targets ({sup 56}Fe and {sup 208}Pb).

Varblane, Urmas; Roolaht, Tõnu

2012-01-01

In several parts of the world, countries are undergoing economic, social, and political transitions, enhanced and accelerated by the forces of globalization. These transition economies can serve as laboratories for understanding the innovation process. This volume features original theoretical and empirical research. It offers the first comprehensive view of innovation system development in the context of small catching-up economies. Smallness, path dependency, and latecomer status of such economies create some inherent limitations for their innovation systems, but these special characteristics can offer advantages as well. For example, smallness is often related with increased flexibility and shorter reaction times, while latecomers can benefit from earlier experiences of their more advanced neighbors. Path-dependency highlights the fact that the innovation system development processes are considerably influenced by the past experience of a particular country or region. By incorporating these features into a...

Palladium supported on natural phosphate: Catalyst for Suzuki coupling reactions in water

2013-01-01

The Suzuki-Miyaura coupling reaction is one of the most important synthetic catalytic reactions developed in the 20th century. However, the use of toxic organic solvents for this reaction still poses a scientific challenge and is an aspect of economical and ecological relevance. The use of water as a reaction medium overcomes this issue. In the present work, we described efficient Suzuki coupling reactions in water, without any phase transfer reagents and it is possible to couple challenging substrates like aryl chlorides. Notably, this protocol also works with ultra-low loading of catalyst with high turnover numbers. © 2012 Elsevier B.V.

An Assessment of the Influence of Selected on the Performance of Small to Medium Sized Family Owned Businesses in the Zimbabwe Retail Sector

2015-10-01

Full Text Available The study attempted to assess the factors that are affecting business performance of small to medium sized family owned businesses in the Zimbabwean retail sector. The objective was to establish the effect of innovation, management skills, succession planning and corporate governance on family owned SMEs in Zimbabwe. The study sought to complement other previous studies that were carried out in other different contexts by producing evidence on the same phenomenon from a developing country context. The study adopted a quantitative approach. A self-administered survey was conducted to collect data that was analysed using descriptive, correlation and regression analyses. The results showed that the most significant factors affecting business performance in order of predictive power were innovation, proper management skills, succession planning and corporate governance. The findings have implications to family business managers and owners in Zimbabwe who are encouraged to be innovative, properly manage, practise succession planning and be guided by business morals in managing their enterprises. Whilst the factors ensuring the success of Small and Medium sized enterprises have extensively been examined, there is dearth of research on family business success factors especially in a developing country like Zimbabwe.

Formation of Anionic C, N-bearing Chains in the Interstellar Medium via Reactions of H- with HC x N for Odd-valued x from 1 to 7

2017-11-01

We investigate the relative efficiencies of low-temperature chemical reactions in the interstellar medium with H- anion reacting in the gas phase with cyanopolyyne neutral molecules, leading to the formation of anionic {{{C}}}x{{{N}}}- linear chains of different lengths and of H2. All the reactions turn out to be without barriers, highly exothermic reactions that provide a chemical route to the formation of anionic chains of the same length. Some of the anions have been observed in the dark molecular clouds and in the diffuse interstellar envelopes. Quantum calculations are carried out for the corresponding reactive potential energy surfaces for all the odd-numbered members of the series (x = 1, 3, 5, 7). We employ the minimum energy paths to obtain the relevant transition state configurations and use the latter within the variational transition state model to obtain the chemical rates. The present results indicate that at typical temperatures around 100 K, a set of significantly larger rate values exists for x = 3 and x = 5, while the rate values are smaller for CN- and {{{C}}}7{{{N}}}-. At those temperatures, however, all the rates turn out to be larger than the estimates in the current literature for the radiative electron attachment (REA) rates, thus indicating the greater importance of the present chemical path with respect to REA processes at those temperatures. The physical reasons for our findings are discussed in detail and linked with the existing observational findings.

Fuelling innovation: Countries look to the next generation of nuclear power

Perera, Judith

2004-01-01

The past few years have seen several multinational initiatives looking at the prospects for the medium and long-term development of nuclear energy. These include: the US-led Generation IV International Forum (GIF), the IAEA's International Project on Innovative Nuclear Reactors and Fuel Cycles (INPRO), and the European Michelangelo network for competitiveness and sustainability of nuclear energy in the EU (Micanet). There have also been two major studies - a joint investigation by the IAEA together with the OECD's International Energy Agency (IEA) and Nuclear Energy Agency (NEA), Innovative Nuclear Reactor Development; Opportunities for International Co-operation; and an interdisciplinary study by the Massachusetts Institute of Technology (MIT) on The Future of Nuclear Energy. All these cover much of the same ground, looking at innovative nuclear systems including reactors and fuel cycles. But, while they were prompted by the same set of underlying imperatives, they also differ to some extent, not least in the importance they attach to the nuclear fuel cycle. GIF and INPRO are two initiatives where enhanced international cooperation could emerge

2014-01-01

Full Text Available Tetracaine hydrochloride (TCH is one of the potent local anaesthetics. A kinetic study of oxidation of tetracaine hydrochloride by sodium N-chlorobenzenesulfonamide (chloramine-B or CAB has been carried in HClO4 medium at 303 K. The rate shows first-order dependence on [CAB]o, shows fractional–order dependence on [substrate]o, and is self-governing on acid concentration. Decrease of dielectric constant of the medium, by adding methanol, increased the rate. Variation of ionic strength and addition of benzenesulfonamide or NaCl have no significant effect on the rate. The reaction was studied at different temperatures and the activation parameters have been evaluated. The stoichiometry of the reaction was found to be 1 : 5 and the oxidation products were identified by spectral analysis. The conjugate free acid C6H5SO2NHCl of CAB is postulated as the reactive oxidizing species. The observed results have been explained by plausible mechanism and the related rate law has been deduced.

Chain Networks as a Leverage for Innovation Capacity: The Case of Food SMEs

Directory of Open Access Journals (Sweden)

Bianka Kühne

2011-02-01

Full Text Available  Nowadays, innovation is no longer limited to the individual firm but involves increasingly the chain network in which the firm is embedded. The chain network is considered as the place where the internal and external resources of a firm are combined and transformed, leading to innovation capacity. In the increasingly globalizing market, innovation is an important strategic tool for small and medium sized enterprises (SMEs to achieve competitive advantage. However, SMEs are often confronted with barriers for developing and introducing innovations, such as the lack of economies of scale. Our paper investigates how the chain network is contributing to the enhancement of the innovation capacity and which chain network characteristics are crucial in this process. In contrast to previous studies at chain network level, in our research specific chain networks are investigated and compared to each other. Hence, data collection took place at different chain network levels, being the supplier, the food manufacturer and the customer, working together and consequently belonging to one specific and unique chain network.The analysis of innovation capacity at the chain network level is realized by means of cluster analysis. This results in a three-cluster solution dividing the sample into Non-innovator chain networks, Customer-driven innovator chain networks and food manufacturer-supplier-driven innovator chain networks. Next, the influence of the chain network on the innovation capacity is examined. Thereby, the three achieved clusters differ significantly related to certain chain network characteristics. The following characteristics form an important leverage for the innovation capacity: firm size, profitability and business growth of the chain network members, as well as higher dependency, and lower levels of integration, rewarding power, social satisfaction and collaboration. The distinction of Customer-driven and food manufacturer

Full Text Available Foreign investments contribute massively to the increase of business profitability. Attraction and efficient allocation of capital inflows (mainly in the form of high quality investment made at microeconomic level represent the main “engine” for GDP growth in medium and long term. This will facilitate private sector access to finance investments, encourage technology transfer and innovation, promote technological parks and business incubators, stimulate innovation and entrepreneurship, support female entrepreneurship, increase efficiency and labor productivity for private companies , as well as management practices based on the principle of investing in people. Analysing the business environment involves, among other things, identifying and removing barriers that produce strain effects of overcoming difficulties for firms, respectively: - the desire that the investment in human capital would have immediate effects; - Insufficient correlation of wage increases and granting bonuses with increasing productivity; - Dialogue and partnerships with universities that could bring competitive advantage stands sometimes in incipient phases;

The GC/AED studies on the reactions of sulfur mustard with oxidants

International Nuclear Information System (INIS)

Popiel, StanisIaw; Witkiewicz, Zygfryd; Szewczuk, Aleksander

2005-01-01

A gas chromatograph coupled with an atomic emission detector was used to identify and to determine the products formed on oxidation of sulfur mustard. The oxidation rate and the resulting oxidates were studied in relation to oxidant type and reaction medium parameters. Hydrogen peroxide, sodium hypochlorite, sodium perborate, potassium monopercarbonate, ammonium peroxydisulfate, potassium peroxymonosulfate (oxone), and tert-butyl peroxide were used as oxidants. Oxidations were run in aqueous media or in solvents of varying polarities. The oxidation rate was found to be strongly related to oxidant type: potassium peroxymonosulfate (oxone) and sodium hypochlorite were fast-acting oxidants; sodium perborate, hydrogen peroxide, ammonium peroxydisulfate, and sodium monopercarbonate were moderate oxidants; tert-butyl peroxide was the slowest-acting oxidant. In non-aqueous solvents, the oxidation rate was strongly related to solvent polarity. The higher the solvent polarity, the faster the oxidation rate. In the acid and neutral media, the mustard oxidation rates were comparable. In the alkaline medium, oxidation was evidently slower. A suitable choice of the initial oxidant-to-mustard concentration ratio allowed to control the type of the resulting mustard oxidates. As the pH of the reaction medium was increased, the reaction of elimination of hydrogen chloride from mustard oxidates becomes more and more intensive

In a double blind prospective study of side effects to cervical myelography 38 patients were evaluated with neurologic examination, electroencephalography (EEG), brainstem evoked response (BER), somatosensory evoked responses (SSER), and continuous reaction times prior to and at 6 h and 24 h after myelography with either metrizamide or iohexol. A difference in the incidence of side effects (for example headache, dizziness, nausea, and neck pain) to the two different contrast media indicated that the inconveniences related to myelography were not only due to the spinal puncture. A contrast medium effect on the central nervous system varying from one agent to another was present. A high frequency of EEG deteriorations among patients with adverse clinical reactions and on only discrete affection upon BER indicated the reaction to be located to the cerebral cortex. Weakened tendon reflexes and reduced strength in the upper extremities were probably caused by blockade in the motor roots as SSER were normal indicating no affection of the sensory pathways. This hypothesis is in agreement with the fact the patients were in the prone position in the first phase of the investigation causing the highest concentration of contrast medium around the motor roots and the anterior part of the spinal cord. Difference in metabolic effect may explain differences in side effects of metrizamide and iohexol. (orig.)

Regularities of development of a unspecific reaction of cells under the effect of different substances belonging to weak electrolytes have been studied. It was demonstrated that the rate of the unspecific reaction development under the effect of cysteamine and caffeine-benzoate depends on the agent concentration, temperature and pH of a medium. It was established that the response of a cell is determined by the overall intracellular concentration of the agent rather than by its specific character. The total concentration of the substance inside the cell depends on its physico-chemical characteristics and, with a pH gradient between cell and medium, can markedly vary from that in the medium. With similar intracellular content, both substances proved to be virtually equally effective. This suggests that it is possible to assess the effectiveness of some other biologically active substances many of which are weak electrolytes

Pion-induced knock-out reactions

Jain, B.K.; Phatak, S.C.

1977-01-01

A strong absorption model for pion-induced Knock-out reactions is proposed. The distortion of the in-coming and out-going pions has been included by (1) computing pion wave number in nuclear medium (dispersive effect) and (2) excluding the central region of the nucleus where the real pion-absorption is dominant (absorption effect). In order to study the dependence of the (π + π + p) reaction on the off-shell pion-nucleon t-matrix, different off-shell extrapolations are used. The magnitude of the cross-sections seems to be sensitive to the type of off-shell extrapolation; their shapes, however, are similar. The theoretical results are compared with experimental data. The agreement between the theoretical results for separable off-shell extrapolation and the data is good. (author)

Full Text Available The study presents a short economic incursion concerning the role of small and medium enterprises in the complex regionalization process of Romania and the impact of this sector on the economic development of the regions, as generating new value. In this paper I have approached aspects related to the problematic of regionalization within the new economic context, which is marked by major turbulence with medium and long-term effects. The development disparities are a reality and, therefore, the interventions of the regional development process is designed to reduce these disparities. Through the case study presented, based on the scientific investigations in the field of small and medium enterprises, I have shown which the analyzed economic disparities are, using the following indicators: the grand domestic product per inhabitant, the number of small and medium enterprises on regions, the number of SMEs in economic sectors and development regions, the average number of employees in SMEs, the share of the turnover in SMEs at the regional level. I have also presented several factors that contribute to eliminate the disparities and develop the regions, focusing on the importance of the innovation and creation process, the development of the human resource, the specialization of regions, infrastructure and accessibility.

Nowadays, the opportunity for companies to be involved in cluster initiatives and international business associations is a major factor that contributes to the increase of their innovative potential. Companies organized in technological clusters have greater access to mutual business contacts, faster information transfer and deployment of advanced technologies. These companies cooperate more frequently with universities and research - development institutions on innovative projects. An important benefit of cluster associations is that they create a suitable environment for innovation and the transfer of knowledge by means of international cooperation and networking. This supportive environment is not easy to access for different small and mediumsized companies, who are not members of any clusters or networks. Supplier-customer business channels expand by means of transnational networks and exchanges of experience. Knowledge potential is broadened and joint innovative projects are developed. Reflecting the growing importance of clusters as driving forces of economic and regional development, a number of cluster policies and initiatives have emerged in the last few decades, oriented to encourage the establishment of new clusters, to support existing clusters, or to assist the development of transnational cooperation. To achieve the goals of the Europe 2020 Strategy, European countries should have an interest in building strong clusters and developing cluster cooperation by sharing specialized research infrastructures and testing facilities and facilitating knowledge transfer for crossborder cooperation. This requires developing a long term joint strategy in order to facilitate the development of open global clusters and innovative small and medium entrepreneurs.

Photooxidative reactions of psoralens

International Nuclear Information System (INIS)

Potapenko, A.Ya.; Sukhorukov, V.L.

1984-01-01

The mechanism and biological significance of photooxidative reactions of psoralens are reviewed. Skin-photosensitizing activities of bifunctional and monofunctional psoralens are compared. Antioxidants tocopherols and butilated hydroxytoluene inhibit photochemical reactions of psoralens responsible for induction of erythema. The same antioxidants do not inhibit PUVA-therapy of psriasis. Though psoralens can generate singlet oxygen under UVA-irradiation (315 - 400 nm), nevertheless singlet oxygen does not play significant role in 8-methoxypsoralen (8-MOP) sensitized photooxidation of tocopherol or dihydroxyphenylalanine (DOPA). SH-compounds enhance the rate of 8-MOP sensitized photooxidation of DOPA by a factor of four, simultaneously the rate of oxidation of SH-groups is enhanced many fold in the presence of DOPA. Under UVA-irradiation in organic solvents psoralens are photooxidized. Dimeric photooxidized psoralens are easily destructed in water medium, their destruction induce oxidation of unsaturated lipids and DOPA. (author)

A two-stage method for inverse medium scattering

KAUST Repository

Ito, Kazufumi

2013-03-01

We present a novel numerical method to the time-harmonic inverse medium scattering problem of recovering the refractive index from noisy near-field scattered data. The approach consists of two stages, one pruning step of detecting the scatterer support, and one resolution enhancing step with nonsmooth mixed regularization. The first step is strictly direct and of sampling type, and it faithfully detects the scatterer support. The second step is an innovative application of nonsmooth mixed regularization, and it accurately resolves the scatterer size as well as intensities. The nonsmooth model can be efficiently solved by a semi-smooth Newton-type method. Numerical results for two- and three-dimensional examples indicate that the new approach is accurate, computationally efficient, and robust with respect to data noise. © 2012 Elsevier Inc.
