Information security doesn’t involve only large organizations. Small and medium-sized companies must closely examine this issue too, because they are increasingly threatened by cyber attacks. Many of them mistakenly believe, that security of their valuable data is sufficient, or that the attackers are not interested in them. Existing standards and methodologies for implementation and management of information security are often hard to transfer to the environment of small and medium-sized bus...

Full Text Available This paper examines government targeted procurement (TP strategies in South Africa and whether these strategies have an influence on the growth performance of Small and medium-sized contractors (SMCs in the construction industry. The rationale for this study stems from reports that while TP has been widely used as an instrument to improve the position of SMCs in the South African construction industry, three out of five SMCs do not become established firms. In addition, the nature of the influence of TP strategies on the growth performance of SMCs is not known. Following a review of existing literature, the study mainly adopted a quantitative research approach. Questionnaire surveys were administered to Construction Industry Development Board (cidb Grades 3 to 6 contractors that have executed TP projects within the last 5 years. The collected data was subjected to descriptive and inferential statistical analyses – Spearman’s rank order correlation was used as an index of association between the study variables. The study found that tendering equity is the most frequently used TP strategy, closely followed by preferencing and mandatory subcontracting. The study also found that positive significant associations exists among preferencing and turnover; third-party management and company assets; tendering equity, turnover and number of employees; as well as accelerated rotations, turnover and number of employees. The study concluded that government intervention through targeted procurement has the potential to achieve its intended results of improving the position of historically disadvantaged SMCs in the construction industry in South Africa if selected and implemented appropriately.

Full Text Available This analysis investigates medium-sized towns in Poland, i.e. those with a population between 20–100 thousand, located up to 100 km away from the main city of the agglomeration. The aim of this article is to compare the level of socio-economic development of Polish towns depending on their location in relation to the main city in the largest agglomerations in 1998 and 2013. Three zones of distance from the main city of each agglomeration have been taken into consideration: a. the inner zone, reaching up to 25 km from the main city; b. the outer zone located at a distance of 25 to 50 km from the main city, and c. the peripheral zone, located at a distance of 50 to 100 km from the main city and including the medium-size towns located outside the agglomeration system. This analysis of the distribution of medium-sized towns and their level of socio-economic development has shown various levels of changes which depend on the distance from the main city of the agglomeration. In 1998, the highest level of development of the medium-sized towns was recorded in towns outside of these agglomeration systems, i.e. those located most remotely from the main city (peripheral zone. Most of the medium-sized towns are situated at a distance of 50–100 km from Warszawa, Kraków, Łódź, Lublin, Gdańsk and have developed their own local, or even regional labour markets and some of them have even provided administrative functions in the past as voivodeship capitals. Only in the Poznań agglomeration, the level of development of medium-sized towns was higher in the immediate surroundings of the main city (25 km. The medium-sized towns in all zones of the distance from the main city in the Wrocław agglomeration represented a similar level of development. By 2013, the level of development of the medium-sized towns in the peripheral zone in all investigated settlement systems had decreased, with a significant improvement in the level of development of the towns in

A study was performed to determine the effect of Conway and f/2 media on the growth of microalgae genera. Genera of Chlorella sp., Dunaliella sp., Isochrysis sp., Chaetoceros sp., Pavlova sp. and Tetraselmis sp. were isolated from the South China Sea. During the cultivation period, the density of cells were determined using Syringe Liquid Sampler Particle Measuring System (SLS-PMS) that also generated the population distribution curve based on the size of the cells. The population of the microalgae genera is thought to consist of mother and daughter generations since these microalgae genera reproduce by releasing small non-motile reproductive cells (autospores). It was found that the reproduction of Tetraselmis sp., Dunaliella sp. and Pavlova sp. could be sustained longer in f/2 Medium. Higher cell density was achieved by genus Dunaliella, Chlorella and Isochrysis in Conway Medium. Different genera of microalgae had a preference for different types of cultivation media.

Summary Using panel data collected in 2005, we evaluate how bank size, discretion over credit, incentive schemes, competition, and the institutional environment affect lending to small- and medium-sized enterprises in China. We deal with the endogeneity problem using instrumental variables, and a reduced-form approach is also applied to allow for weak instruments in estimation. We find that total bank asset is an insignificant factor for banks’ decision on small- and medium-enterprise (SME) lending, but more local lending authority, more competition, carefully designed incentive schemes, and stronger law enforcement encourage commercial banks to lend to SMEs.

To work in a medium-size enterprise in the nuclear sector

International Nuclear Information System (INIS)

Le Ngoc, B.

2017-01-01

The French nuclear industry is made up of 2500 enterprises of any size from family businesses to large groups via medium-sized enterprises and start-ups. Most small and medium-sized enterprises have difficulties to recruit qualified people whereas their order books are full. These difficulties originate from the fact that these enterprises are less known than EDF, AREVA and CEA and as a consequence less chosen by job applicants. There is another point, the image of the industry has progressively deteriorated and the idea of working in an industrial sector is no more very exciting. The last point is that nuclear industry's future may appear less clear because of the government's policy of reducing the nuclear share in power production through the early decommissioning of reactors. 3 medium-size enterprises of the nuclear sector: Assystem, REEL and Onet Technologies consider to recruit a total of about 800 people per year and give 4 reasons to join a medium-sized company: 1) a faster professional career, more diverse activities in the job, closer managing executives and a dynamic and stimulating workplace.

2012-01-01

Full Text Available Numerous studies in the world of market economy show that the share of small and medium size enterprises is constantly increasing compared to large enterprises. This does not decrease the significance of large enterprises, but the dependence between them gets larger every day. National economies which manage to find the optimal combination between small, medium size and large enterprises are more successful than the others. Management of small and medium size enterprises (SMEs in conceptual terms is similar to the process of management of large enterprises. An organization must be managed in order to function and this rule applies to small and medium size enterprises.

Full Text Available This paper represents a pilot study examining entrepreneurial behavior patterns within the area of development of micro, small and medium-sized market active enterprises in South Moravian Region from the perspective of strategic management. The main aim of this article is to classify the enterprises by the character of development activities into relatively homogeneous groups and identify those activities that contribute to considerable differences between the individual groups. Empirical evidence is based on a quantitative survey in terms of a random choice of respondents obtained by means of an e-mail questionnaire. The major analytic procedure applied within this research comprises methods of Cluster Analysis and validation technique based on chi-square and G-square nonparametric tests for testing differences (independence of variables between the clusters. By means of Cluster Analysis three relatively homogenous SME groups were identified. The first cluster, called “global”, (approximately 6% of the respondents prevails in most of the strategic development aspects of the researched enterprises. Global SMEs rely on development activities in the area of product innovations and risk diversification into other activities. In terms of changes in functional strategies this involves primarily the area of new technology and human resources development, and the ability to benefit from participation in networks of cooperating organizations. The second cluster, called “transition”, (approximately 59% of the respondents is developed mainly by means of investments in business specific knowledge, and/or in technical skills of their employees. They are more conservative in the area of product innovations and risk diversification into other activities, which is then reflected in a lower level of investments in technologies and marketing. In comparison with global enterprises the major difference lies in a much lower number of activities in the area

Small and medium-sized nuclear power plants

Schmidt, R.

1986-01-01

Small and medium-sized nuclear power plants have long been under discussion as possible applications of nuclear power in countries with small transmission grid systems, in threshold countries and developing countries, and under special local supply conditions. IAEA has condensed and promoted this interest and tried to establish the demand, and possibilities of meeting it, in special events and campaigns. In recent years, considerable interest was registered even in industrialized countries, but here specially for heating and process heat generation applications and for special purposes and, in medium-sized units, also for combined supplies of electricity and heat. This corresponds to special reactor and plant concepts, some of which have already been developed to a stage at which construction work could begin. The analysis presented deals with necessary preconditions on the sides of the users and the vendors, with problems of economy, infrastructure and financing and with the market prospects of small nuclear power plants.

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)

1983-01-01

The Ministry of International Trade and Industry has made a report on the results of the study on the utilization of small and medium size LWRs. The Japan Atomic Industrial Forum undertook this research work by the commission of the Ministry. It studied six cases of PWRs and BWRs with thermal output power ranging from 20 MWt to 700 MWt as the hypothetical design for their siting conditions, reactor capacity and the examples of utilization of the corresponding steam output. A large housing estate of 5,000 units, a local core city with population of 100,000, industrial utilization for petrochemical plants and paper and pulp plants and the combined utilization for a factory and a housing estate of 5,000 units were examined. The report said that a city with population of 100,000 would be the best object to supply heat from a nuclear reactor, and it is important to develop the nuclear reactors with 200 MWt capacity. This type is versatile in the siting conditions, and can be constructed near a city, accordingly, it offers the possibility of extensive utilization. The significance of small and medium size LWRs as the alternative energy for oil, the regional development accompanying the use of small and medium size LWRs, the technical development toward scale reduction, easy operation and versatile utilization, the economical evaluation of the utilization models and the tasks for the future are reported.

CEA (TECHNICATOME) has developed a range of pressurized water reactors of the type ''CAS compact'' which are adapted to civil ship propulsion, or to electric power production, combined possibly with heat production, up to outputs equivalent to 125 MWe. Nuclear plants equipped with these reactors are suitable to medium-size electric networks. Among the possible realizations, two types of plants are mentioned as examples: 1) Floating electron-nuclear plants; and 2) Combined electric power and desalting plants. The report describes the design characteristics of the different parts of a 125 MWe unit floating electro-nuclear plant: nuclear steam system CAS 3 G, power generating plant, floating platform for the whole plant. The report gives attention to the different possibilities according to site conditions (the plant can be kept floating, in a natural or artificial basin, it can be put aground, ...) and to safety and environment factors. Such unit can be used in places where there is a growing demand in electric power and fresh water. The report describes how the reactor, the power generating plant and multiflash distillation units of an electric power-desalting plant can be combined: choice of the ratio water output/electric power output, thermal cycle combination, choice of the gain ratio, according to economic considerations, and to desired goal of water output. The report analyses also some technical options, such as: choice of the extraction point of steam used as heat supply of the desalting station (bleeding a condensation turbine, or recovering steam at the exhaust of a backpressure turbine), design making the system safe. Lastly, economic considerations are dealt with: combining the production of fresh water and electric power provides usually a much better energy balance and a lower cost for both products. Examples are given of some types of installations which combine medium-size reactors with fresh water stations yielding from 10000 to 120000 m 3 per day

A better understanding of biological effects of nanomaterials in organisms requests knowledge of the physicochemical properties of nanomaterials in biological systems. Affected by high concentration salts and proteins in biological medium, nanoparticles are much easy to agglomerate,hence the difficulties in characterizing size distribution of the nanomaterials in biological medium.In this work, synchrotron radiation small angle X-ray scattering(SR-SAXS) was used to determine size distributions of Fe, Fe 2 O 3 and Fe 3 O 4 nanoparticles of various concentrations in PBS and DMEM culture medium. The results show that size distributions of the nanomaterials could perfectly analyzed by SR-SAXS. The SR-SAXS data were not affected by the particle content and types of the dispersion medium.It is concluded that SR-SAXS can be used for size measurement of nanomaterials in unstable dispersion systems.

Perspective on small and medium size reactors

International Nuclear Information System (INIS)

Stahlkopf, K.E.; Braun, C.

1985-01-01

There has been renewed interests in the United States in small and medium size nuclear power plants (600 MWe or less). The reasons for this include: (1) there is a large uncertainty in load growth projections. Small to medium size nuclear power plants may be better suited to meet uncertain load growth projections. (2) It has been argued that a large economy of scale exists because of the nature of nuclear power installations. A recent examination of the French program shows that no economy of scale exists between the 900 MWe and 1300 MWe plants. Others have suggested that it is possible to reduce the economy of scale so it is not a prohibitive factor. (3) In the past in the United States, it has been customary for several smaller utilities to share the output of a large nuclear plant to take advantage of the perceived economy of scale. Difficulties have been encountered by some of these enterprises. (4) An examination of capacity factors for the United States shows that plants of smaller output appear to operate more reliably and economically than larger plants

2002-12-01

Preliminary assessment for deployment of small-medium sized reactor (S and M reactor) as a future option has been conducted at the JAPCO (Japan Atomic Power Company) under the cooperation with the CRIERI (Central Research Institute of Electric Power Industry). Significance of the S and M reactor introduction is listed as follows; lower investment cost, possible siting near demand side, enlarged freedom of siting, shorter transmission line, good compatibility with slow increase of demand and plain explanation of safety using simpler system such as integral type vessel without piping, natural convection core cooling and passive safety system. The deployment of simpler plant system, modular shop fabrication, ship-shell structured building and longer operation period can assure economics comparable with that of a large sized reactor, coping with scale-demerit. Also the S and M reactor is preferable in size for the nuclear heat utilization such as hydrogen production. (T. Tanaka)

Medium-size power plants. Economic options

Vogelweith, L.; Baujat, J.; Goutail, J.

1978-01-01

In this paper the authors describe a method for economic evaluation of a nuclear power plant project such as advocated by the IAEA but modified through the introduction of various parameters that may affect the evaluation, i.e. the weighted evaluation rate, the annual increase in the cost of fuel, and the discount rate. The method is applied to barge-based medium-size reactors (125 MW(e)). The authors calculate the investment cost, together with the costs of administration, operation and maintenance; use is made of current assumptions regarding the price of fuel for the case of a reference nuclear plant and an oil-fired plant of the same power and in the same programme. In this way the authors derive the discounted cost of the nuclear programme and concurrent conventional programme on the basis of the following assumptions: a weighted inflation rate varying between 0 and 6% per year; an annual increase in real fuel prices ranging from 0 to 3%; and a real discount rate, equal to the real interest rate, varying between 4 and 7% per year and corresponding to nominal discount rates of up to 13.4%. The conclusion reached is that, given the real interest rates actually prevailing on the financial market, a weighted inflation rate foreseen by the majority of experts, and a rise in real fuel prices of the order of 1% per year, the medium-size nuclear power plant is more economical than a conventional plant of the same output.

CAS medium-size nuclear plants

International Nuclear Information System (INIS)

Vogelweith, L.; Weiss, A.

1977-01-01

CEA has developed a range of pressurized water reactors of the type CAS Compact, which are adapted to civil ship propulsion, or to electric power production, combined possibly with heat production, up to outputs equivalent to 125MW(e). Nuclear plants equipped with these reactors are suitable for medium-size electric networks, especially in developing countries, because they are easily adaptable, owing to their flexibility; they can be installed and used in a variety of ways (on land, floating installation, combination of electric power and other production, etc.); they can be used as training reactors by countries wishing to limit their investment plans before undertaking a wider nuclear development. Examples of two possible realizations are presented: as a floating plant, and as a combined electric and desalting plant. (author)

[Management practices in medium-sized private hospitals in São Paulo, Brazil].

Brito, Luiz Artur Ledur; Malik, Ana Maria; Brito, Eliane; Bulgacov, Sergio; Andreassi, Tales

2017-04-03

Traditional management practices are sometimes considered merely a necessary condition for superior performance. Other resources and competencies with higher barriers to imitation are assumed to be potential sources of competitive advantage. This study describes and analyzes the effect of traditional management practices on the performance of medium-sized hospitals. Medium-sized companies frequently display the greatest differences in management practices, and only recently did the hospital sector seek ways to develop its competitiveness in the administrative arena. The results generally indicate that basic management practices can make differences in performance, offering support for the new practice-based view (PBV). Hospitals with the highest rate of adoption of practices had the highest occupancy rate, hospital-bed admissions, and accreditation. Lack of adoption of management practices by medium-sized hospitals limits their competitive capacity and can be viewed as a component of the so-called Brazil cost, but in this case an internal component.

Full Text Available Small and medium sized enterprises play an essential role in the economy of the Czech Republic as a report of development of small and medium-sized enterprises and its support from 2010 announces. They are the source of development of towns, regions and the state itself. Small and medium-sized enterprises represent 99.84 % of the whole business subjects. Statistic data underline this position- they indicate that small and medium-sized enterprises employ 2/3 employees. Therefore, occupying small and medium-sized enterprises are to be taken as priority.Strategic management on the level of small and medium-sized enterprises is, as number of authors write, diverse. Small enterprises including micro have less access to capital, they have no money for employing specialists in the field, and they solve administration primarily. The aim of this follow-up GAJU project contribution concerned on process analysis of small and medium-sized enterprises is to summarize the gained results from the view of comparison of the level of strategic management in small and medium-sized enterprises.Nowadays, numbers of enterprises are thinking about whether they are able to remain in the market as an established company, they explore the possibility of improving its position. There is a question for small and medium-sized enterprises management- can strategic management be used as an instrument for increasing competitiveness? The results show that SMEs with a clearly defined strategy show better results of financial health (IN99 and ROA than companies without a defined strategy. In terms of business focus, we were able to demonstrate positive relationship between strategy and finance only for companies in the construction industry, on the significance level of 0.05.

NONE

2002-08-01

During the early years of nuclear power deployment, the plants entering service were dominated by what are now considered small (less than 300 MW(e)) and medium (300 to 700 MW(e)) reactors. In the late 1970s, the balance shifted to larger size plants to serve the requirements of industrialized countries. However, since the early 1990s, the increased interest of developing countries in nuclear power, mainly in Asia, has resulted in intensified efforts in development of small and medium sized reactors (SMRs). Also, in industrialized countries, electricity market deregulation is calling for power generation flexibility that SMRs may offer. Apart from electricity generation, SMRs are of particular interest for non-electrical applications of nuclear energy, such as desalination of seawater and district heating. In recognition of the current global interest in small and medium sized reactors this seminar was convened to provide a forum for the exchange of information by experts and policy makers from industrialized and developing countries on the technical, economic, environmental, and social aspects of SMR development and implementation in the 21st century, and to make this information available to all interested IAEA Member States. Keynote addresses also provided information on global energy demand and supply and international trends impacting the development and introduction of SMRs. Two hundred forty seven attendees from 39 countries and 5 international organizations participated in the seminar. The majority of the participants were from developing countries. The seminar not only provided valuable up to date information on SMRs, it also highlighted the importance of continued international co-operation in the development and application of nuclear power for peaceful uses throughout the world.

Full Text Available The authors prove that despite the active state policy carried out since the second half of the 2000s and aimed at supporting small and medium-sized business in the Russian Federation, the current level of development of this economic sector is insufficient. The present paper characterizes the modern structure of small and medium-sized business. The authors show that the main problems hindering its growth are conditioned by low market demand, large tax deductions, numerous administrative barriers, lack of funding and state support. On the basis of the official data of Russian Federal State Statistics Service on theresults of annual surveys of entrepreneurs, the authors revealed the factors that prevented innovation situation in the country have stable negative impact on MSB, while the impact of such factors as imperfect legal and regulatory framework, investment risks, low profitability and inadequate state of technological infrastructure is relatively nonsignificant. The authors describe systemwide and resource measures of state regulation of small and medium-sized business. The system-wide measures include preferential access to production facilities and equipment, special tax regimes, administrative control. The measures of resource support to entrepreneurs consist in subsidizing the lease payments and interest rates on loans for the modernization of production; grant support, the establishment of microfinance organizations and guarantee funds, the development of business support infrastructure. The authors describe the forms of these measures implementation in 2013 and the main directions of improving the state regulation of small and medium-sized business, including the reduction of tax burden and facilitation of taxation procedures, the reduction of administrative barriers and ensuring access of small and medium-sized enterprises to government orders and technological infrastructure.

The CANDU 6 Pressurized Heavy Water Reactor system, featuring horizontal fuel channels and heavy water moderator continues to evolve, supported by AECL's strong commitment to comprehensive R and D programs. The initial CANDU 6 design started in the 1970's. The first plants went into service in 1983, and the latest version of the plant is under construction in China. With each plant the technology has evolved giving the dual advantages of proveness and modern technology. CANDU 6 delivers important advantages of the CANDU system with benefit to small and medium-sized grids. This technology has been successfully adopted by, and localized to varying extents in, each of the CANDU 6 markets. For example, all CANDU owners obtain their fuel from domestic suppliers. Progressive CANDU development continues at AECL to enhance this medium size product CANDU 6. There are three key CANDU development strategic thrusts: improved economics, fuel cycle flexibility, and enhanced safety. The CANDU 6 product is also enhanced by incorporating improvements and advanced features that will be arising from our CANDU Technology R and D programs in areas such as heavy water and tritium, control and instrumentation, fuel and fuel cycles, systems and equipment and safety and constructability.

THE STRATEGIC RELEVANCE OF TECHNOLOGY-RELATED VARIABLES TO THE COMPETITIVENESS OF SMALL - TO MEDIUM-SIZED FURNITURE MANUFACTURERS

Directory of Open Access Journals (Sweden)

Lourens, A. S.

2012-11-01

Full Text Available SMMEs can make a critical and positive economic contribution to South Africa, and small- to medium-sized furniture manufacturers (SM/FMs have the potential to contribute to economic growth, job creation, and GDP. However, the furniture industry has not stayed abreast of technological advances. To survive in an environment of increasing competition and imports, competitive strategies must be devised. One such strategy is for technology adoption and implementation that can provide solutions for the furniture industry to improve speed, quality, variety, flexibility, and productivity, resulting in improved competitiveness. However, the adoption of technology means that its acquisition and application must be managed strategically, as the use of technology involves far more than simply taking it into account during the business-plan

Full Text Available The purpose of this article is to show the relationship between branding and brand management in small and medium-sized enterprises (SMEs. Traditionally, branding was associated with large and global corporations. However, we often forget that small and medium-sized enterprises also deal with their own names (brands in their own way. The study identified four types of businesses, regardless of their association with brands. We named these four types, as follows: Ignorant; User; Low-Cost Producer; and Differentiation Producer. If the first two types (i.e. Ignorant and User differ primarily in the extent to which they use simple branding activities, and are used mainly in the local market where the enterprises tend to operate, we found that the last two types (i.e. low-cost producers and differentiation producers design their branding strategies in accordance with their generic strategies and mode of growth.

Vaas, Jocelyn R

2008-04-01

The primary purpose of this study was to assess the role, status and scope of workplace HIV/AIDS committees as a means of effective workplace governance of the HIV/AIDS impact, and their role in extending social protective HIV/AIDS-related rights to employees. In-depth qualitative case studies were conducted in five South African small and medium-sized enterprises (SMEs) that were actively implementing HIV/AIDS policies and programmes. Companies commonly implemented HIV/AIDS policies and programmes through a workplace committee dedicated to HIV/AIDS or a generic committee dealing with issues other than HIV/ AIDS. Management, through the human resources department and the occupational health practitioner often drove initial policy formulation, and had virtually sole control of the HIV/AIDS budget. Employee members of committees were mostly volunteers, and were often production or blue collar employees, while there was a notable lack of participation by white-collar employees, line management and trade unions. While the powers of workplace committees were largely consultative, employee committee members often managed in an indirect manner to secure and extend social protective rights on HIV/AIDS to employees, and monitor their effective implementation in practice. In the interim, workplace committees represented one of the best means to facilitate more effective workplace HIV/AIDS governance. However, the increased demands on collective bargaining as a result of an anticipated rises in AIDS-related morbidity and mortality might prove to be beyond the scope of such voluntary committees in the longer term.

Buildings consume over 40% of the total energy consumption in the U.S. A significant portion of the energy consumed in buildings is wasted because of the lack of controls or the inability to use existing building automation systems (BASs) properly. Much of the waste occurs because of our inability to manage and controls buildings efficiently. Over 90% of the buildings are either small-size (<5,000 sf) or medium-size (between 5,000 sf and 50,000 sf); these buildings currently do not use BASs to monitor and control their building systems from a central location. According to Commercial Building Energy Consumption Survey (CBECS), about 10% of the buildings in the U.S. use BASs or central controls to manage their building system operations. Buildings that use BASs are typically large (>100,000 sf). Lawrence Berkeley National Laboratory (LBNL), Oak Ridge National Laboratory (ORNL) and Pacific Northwest National Laboratory (PNNL) were asked by the U.S. Department of Energy’s (DOE’s) Building Technologies Program (BTP) to identify monitoring and control needs for small- and medium-sized commercial buildings and recommend possible solutions. This study documents the needs and solutions for small- and medium-sized buildings.

2004-01-01

This paper presents the results obtained using a genetic algorithm (GA) to search for stable structures of medium size silicon clusters. In this work the GA uses a semiempirical energy function to find the best cluster structures, which are further optimized using density-functional theory. For small clusters our results agree well with previously reported structures, but for larger ones different structures appear. This is the case of Si 36 where we report a different structure, with significant lower energy than those previously found using limited search approaches on common structural motifs. This demonstrates the need for global optimization schemes when searching for stable structures of medium-size silicon clusters

Imaging and size measurement of nanoparticles in aqueous medium by use of atomic force microscopy.

Size control of nanoparticles in nanotechnology-based drug products is crucial for their successful development, since the in vivo pharmacokinetics of nanoparticles are size-dependent. In this study, we evaluated the use of atomic force microscopy (AFM) for imaging and size measurement of nanoparticles in aqueous medium. The height sizes of rigid polystyrene nanoparticles and soft liposomes were measured by AFM and were compared with the hydrodynamic sizes measured by dynamic light scattering (DLS). The lipid compositions of the studied liposomes were similar to those of commercial products. AFM proved to be a viable method for obtaining images of both polystyrene nanoparticles and liposomes in aqueous medium. For the polystyrene nanoparticles, the average height size observed by AFM was similar to the average number-weighted diameter obtained by DLS, indicating the usefulness of AFM for measuring the sizes of nanoparticles in aqueous medium. For the liposomes, the height sizes obtained by AFM differed depending upon the procedures of immobilizing the liposomes onto a solid substrate. In addition, the resultant average height sizes of the liposomes were smaller than those obtained by DLS. This knowledge will help the correct use of AFM as a powerful tool for imaging and size measurement of nanotechnology-based drug products for clinical use.

French hydro-power buildings belong to the government and are retroceded by the licence holder when the granting delay comes to an end. Experience has shown that less care is given by licence holders to the maintenance of medium-size dams that to big dams. For this reason, the French Ministry of Industry decided to harmonize and standardize the surveillance practices of medium-size dams. A circular was signed on May 23, 1997 which concerns the 10 to 20 m height dams with water reservoir volumes lower than the H{sup 2} x V{sup 0.5} criterion which is an evaluation of the potential risk of the dam. The surveillance modalities concern: the construction, the licence holder file, the first filling up, the operation, and the periodical safety inspections. (J.S.)

Full Text Available Background: Small and medium-sized enterprises (SMEs, especially in the Western Cape Province of South Africa, are currently facing various financial and other obstacles, which may threaten their survival. Globalisation, the lowering of trade barriers and the reduction of import tariffs have resulted in increased international competition. Businesses are thus forced to undertake continuous improvements and innovation in order to survive, to keep abreast of change and to excel.Objectives: Effective knowledge sharing and consequent knowledge management (KM have been identified as definite approaches to enhancing competitive advantage. The research therefore aimed to establish to what extent small enterprises embrace their knowledge sharing activities and whether their knowledge sharing activities are managed at all. Furthermore, it examined how their knowledge sharing can contribute to their competitive advantage.Method: A case study approach was followed for this research. Selected SMEs from the engineering sector were the subject of the case study and SME owners, directors and managers of consulting civil engineering firms were interviewed to determine whether there are mechanisms in place to ensure better knowledge sharing within SMEs.Results: In general, respondents had stated that they possessed special factors that set them above their competitors:• The company strategy and good reputation of completing projects within the required timeframe. In other words, they were well known for their track record in terms of service delivery. • Their specialty in terms of different focus areas, namely structural and civil engineering, water supply and storm water design, transportation, sewer design and storm water traffic. • The fact that they operated in silos. This means that the specialists in their specific fields operated independently in groups, separately from everyone else in the company. • Their good relationship with local authorities

2011-01-01

This study, through a random national survey in the U.S., explored how corporate financial decision-makers perceive important workplace safety issues as a function of the size of the company for which they worked (medium- vs. large-size companies). Telephone surveys were conducted with 404 U.S. corporate financial decision-makers: 203 from medium-size companies and 201 from large companies. Results showed that the patterns of responding for participants from medium- and large-size companies were somewhat similar. The top-rated safety priorities in resource allocation reported by participants from both groups were overexertion, repetitive motion, and bodily reaction. They believed that there were direct and indirect costs associated with workplace injuries and for every dollar spent improving workplace safety, more than four dollars would be returned. They perceived the top benefits of an effective safety program to be predominately financial in nature - increased productivity and reduced costs - and the safety modification participants mentioned most often was to have more/better safety-focused training. However, more participants from large- than medium-size companies reported that "falling on the same level" was the major cause of workers' compensation loss, which is in line with industry loss data. Participants from large companies were more likely to see their safety programs as better than those of other companies in their industries, and those of medium-size companies were more likely to mention that there were no improvements needed for their companies.

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.

Analysis of near optimum design for small and medium size nuclear power plants

International Nuclear Information System (INIS)

Ahmed, A.A.

1977-01-01

Market surveys in recent years have shown that a significant market would exist among the developing nations of the world for nuclear power plants that would be classified as small to medium sized, provided that these small plants could produce electricity at a unit price comparable to that of equivalent sized fossil fired plants. Nuclear plants in the range of 100 MWe to 500 MWe would fit more effectively into the relatively smaller grids of most developing nations than would the 900 MWe to 1300 MWe units now being constructed in the large industrial nations. Worldwide re-evaluation of the worth of fossil fuels has prompted a re-examination of the competitive position of small to medium sized nuclear generating units compared to comparable fossil fired units, especially in the context of units specifically optimized for the size range of interest, rather than of designs that are simply scaled down versions of the currently available larger units. Since the absolute cost of electricity is more sensitive to external factors such as cost of money, national inflation rate and time required for licensing and construction than to details of design or perhaps even to choice of fuels, and since the cost of electricity generated in small to medium sized fossil fired units is periodically compared to that of scaled down versions of conventional large nuclear units, the point of view taken here is one of comparing the relative generating costs of smaller nuclear units of optimum design with the corresponding costs of scaled down versions of current large nuclear generating units

Full Text Available On existing conditions on global market (almost identical quality, almost identical purchasing values companies have to definite the total rating of importance of evaluative criteria. In post-crisis period the problem of suppliers’ evaluation is one of the biggest, because companies had to use all resources and all possibilities to develop their own business. Many authors wrote about collaborative planning and warehousing as one of possibilities to optimization work inside supply chain. For this paper define small and medium-sized enterprises (SME as enterprises with the size of maximum 250 em­ployers. In literature was read we couldn’t find information about own system of suppliers evaluation for small and medium-sized enterprises. SME can have some different types of business and in this case need the universal system of eva­lua­tion. The research of this paper is oriented on small and medium-sized enterprises with different types of business. The new theoretical universal method of calculation for evaluation existing suppliers for small and medium-sized enterprises will present in this paper. This theoretical method is based on average values. This method includes traditional evaluative criteria (quality, delivery time and other (mobility of supplier, possibilities of new level of partnership. This method of evaluation can not be used for continual manufacture. New method can improve the total evaluation of supplier in small and medium-sized enterprises.

Objective To prospectively evaluate the safety and short-term therapeutic efficacy of switching monopolar radiofrequency ablation (RFA) with multiple electrodes to treat medium-sized (3.1-5.0 cm), hepatocellular carcinomas (HCC). Materials and Methods In this prospective study, 30 patients with single medium-sized HCCs (mean, 3.5 cm; range, 3.1-4.4 cm) were enrolled. The patients were treated under ultrasonographic guidance by percutaneous switching monopolar RFA with a multichannel RF generator and two or three internally cooled electrodes. Contrast-enhanced CT scans were obtained immediately after RFA, and the diameters and volume of the ablation zones were then measured. Follow-up CT scans were performed at the first month after ablation and every three months thereafter. Technical effectiveness, local progression and remote recurrence of HCCs were determined. Results There were no major immediate or periprocedural complications. However, there was one bile duct stricture during the follow-up period. Technical effectiveness was achieved in 29 of 30 patients (97%). The total ablation time of the procedures was 25.4 ± 8.9 minutes. The mean ablation volume was 73.8 ± 56.4 cm3 and the minimum diameter was 4.1 ± 7.3 cm. During the follow-up period (mean, 12.5 months), local tumor progression occurred in three of 29 patients (10%) with technical effectiveness, while new HCCs were detected in six of 29 patients (21%). Conclusion Switching monopolar RFA with multiple electrodes in order to achieve a sufficient ablation volume is safe and efficient. This method also showed relatively successful therapeutic effectiveness on short-term follow up for the treatment of medium-sized HCCs. PMID:22247634

To describe the meals consumed by adults living in a midsize city in the South of Brazil, according to the place and preparation. A population-based cross-sectional study was conducted in Pelotas, Southern Brazil, in 2012. The two-stage sampling design used the 2010 census tracts as primary sampling units. Data were collected on the place of meals (at home or out) and on the kind of preparations consumed at home (homemade, snacks, take away food) covering the two days prior to the interview, using a standardized questionnaire. The study included 2,927 adults, of which 59.0% were female, 60.0% were below 50 years of age and 58.0% were in work. Data were collected on 11,581 meals consumed on the two days preceding the interview, 25.0% were consumed outside of the home at lunchtime, and 10.0% at dinnertime. Considering home meals, most participants reported eating food prepared at home at both lunch and dinner. The majority of out-of-home meals (64.0% for lunch and 61.0% for dinner) were consumed in the work place, mostly based on food prepared at home. Individuals eating out of home were mostly male, young and highly educated. The occupational categories that ate at restaurants more often were trade workers, businessmen, teachers and graduate professionals. Despite the changes in eating patterns described in Brazil in recent years, residents of medium-sized towns still mostly eat at home, consuming homemade food.

2012-01-01

Full Text Available The objective of this article is to study the relations among financial indicators, competitiveness and business ethics of comparable small and medium-sized enterprises. A sample of 59 SMEs from the South Moravia region was chosen. All selected companies either produce or service electronics. This research is based on the application of scientific analysis, synthesis, induction, fuzzy logic and modeling. Information for this research was obtained from secondary information sources – Amadeus database, accounting statements and information from the register of companies. Each company is described by a set of 10 variables. Fuzzy sets and reasoning are ideal tools to cope with vague, ill-structured and uncertain scenarios which can be found frequently in business and economics. This is the main reason why fuzzy logic was used in this research. The paper is self-explanatory and no a prior knowledge of fuzzy reasoning is required.

Martinez, Luis F; Ferreira, Aristides I; Can, Amina B

2016-04-01

Based on Szulanski's knowledge transfer model, this study examined how the communicational, motivational, and sharing of understanding variables influenced knowledge transfer and change processes in small- and medium-sized enterprises, particularly under projects developed by funded programs. The sample comprised 144 entrepreneurs, mostly male (65.3%) and mostly ages 35 to 45 years (40.3%), who filled an online questionnaire measuring the variables of "sharing of understanding," "motivation," "communication encoding competencies," "source credibility," "knowledge transfer," and "organizational change." Data were collected between 2011 and 2012 and measured the relationship between clients and consultants working in a Portuguese small- and medium-sized enterprise-oriented action learning program. To test the hypotheses, structural equation modeling was conducted to identify the antecedents of sharing of understanding, motivational, and communicational variables, which were positively correlated with the knowledge transfer between consultants and clients. This transfer was also positively correlated with organizational change. Overall, the study provides important considerations for practitioners and academicians and establishes new avenues for future studies concerning the issues of consultant-client relationship and the efficacy of Government-funded programs designed to improve performance of small- and medium-sized enterprises. © The Author(s) 2016.

Full Text Available Abstract :Due to their significant role in creation of new jobs, rise in GDP, entrepreneurship and innovation, small and medium-sized enterprises (SMEs are recognized as the the drivers of socio-economic growth, both in developed and developing economies. In Turkey, 99.9 % of all enterprises fall into SME category. Therefore, the significance of SMEs for Turkish economy and society is much higher in Turkey, compared to other emerging and developed countries. Small and medium-sized companies are faced with a number of challenges whereas the problems arising from “poor financial management” are reported as the major causes of business failures in SMEs. Strategic financial management (SFM which is a research area that has attracted the interest of researchers after 2010, is one of the key managerial areas of SMEs, due to its vital role on the survival, growth and performance of SMEs. The purpose of this paper is to analyze the central role of financial management and identify the financial management challenges and practices that influence the organizational performance in Turkish SMEs, from a strategic management perspective. Within the course of this paper, the importance and challenges of SMEs in Turkey are presented in the first section, while the literature on strategic and financial management in SMEs are reviewed in the second part. In the third section, the recent strategic financial management concept, the implications of strategic financial management practices for SMEs in Turkey and the relationships between strategic financial management practices and SME performance, are discussed. Small and medium sized enterprise finance in Turkey is a developing research area, therefore this paper aims to make a significant contribution to the existing literature by analyzing the major challenges at the conduct of financial management in Turkish SMEs and the influence of strategic financial management practices on the performances of small and

Possible pathways to the market are described—laboratory testing to market adoption to commercialization. We also identify and address various technical and market barriers that could hinder deployment of VOLTTRON. Finally, we provide “best practice” tech-to-market guidance for building energy-related deployment efforts serving small- and

Depressurization accidents in a medium-sized high-temperature gas reactor

International Nuclear Information System (INIS)

Ron, S.; Tzoref, J.; Gal, D.

1992-01-01

The amount of fission product release during a core heatup accident in a medium-sized high-temperature gas reactor depends on the size of the inadvertent opening in the primary circuit; this dependence is assessed. The opening triggers a depressurization event that is assumed to be coupled with the failure of the forced circulation in both decay-heat removal systems. The scenario investigated is a beyond-design-base accident. The DSNP modular simulation code is used. This paper reports that a two-dimensional model is developed to simulate the HTR-500 design. The study shows that the depressurization process does not contribute significantly to the sweeping out (from the primary circuit) of fission products released from the fuel during the core heatup. There is also no significant variation in the results when the opening size is >33 cm 2 , and only a slight sensitivity is found when the rupture size is between 3.3 and 33 cm 2 . The fission product release decreases considerably in the range from 1 to 3.3 cm 2 . The small-sized rupture is of major significance, as the failure of the relief valves to reclose increases the frequency of the event

1980-08-01

This report summarizes high-temperature gas-cooled reactor (HTGR) experience for the 40-MW(e) Peach Bottom Nuclear Generating Station of Philadelphia Electric Company and the 330-MW(e) Fort St. Vrain Nuclear Generating Station of the Public Service Company of Colorado. Both reactors are graphite moderated and helium cooled, operating at approx. 760 0 C (1400 0 F) and using the uranium/thorium fuel cycle. The plants have demonstrated the inherent safety characteristics, the low activation of components, and the high efficiency associated with the HTGR concept. This experience has been translated into the conceptual design of a medium-sized 1170-MW(t) HTGR for generation of 450 MW of electric power. The concept incorporates inherent HTGR safety characteristics [a multiply redundant prestressed concrete reactor vessel (PCRV), a graphite core, and an inert single-phase coolant] and engineered safety features

European Health Claims for Small and Medium-Sized Companies – Utopian Dream or Future Reality?

2015-02-01

Full Text Available Background: In December 2007, the European Regulation (EC 1924/2006 on nutrition and health claims came into force. The European Union wanted to regulate the use of health claims on products. An online survey was carried out to evaluate the situation, particularly of small and medium-sized companies, dealing with the new regulation. Methods: The online survey on health claims was conducted with 16 enterprises. To underline the findings a SWOT (Strength, Weaknesses, Opportunities, Threats analysis was made of the nutrition and health claims regulation regarding small and medium-sized companies in the European food and drink market. Results: The findings of this study indicated that the European Union did a step in the right direction. Most companies defined the decent competition, the simplified trade within the inner-European market, and the consumer protection as positive aspects. The biggest threat is seen in false investment conditioned by the limited research and development budgets, especially of small and medium-sized enterprises, and the cost intensive scientific evaluation to reach an authorized health claim. Conclusions: Overall, there are several strengths and opportunities speaking for SMEs and health claims in the near future. The most promising ones are the publishing of the new European Union Register of Nutrition and Health Claims and the learning effects that will occur. The biggest threat is, and will remain to be, false investment and the possible loss of a lot of money. Nevertheless, health claims for small and medium-sized enterprises will inevitably be the future to keep the European food and drink market competitive.

To evaluate contemporary management approaches to medium-sized (10-20 mm) renal stones. A total of 935 patients treated for medium-sized renal stones (10-20 mm) between July 2012 and March 2014 were included in the study program. Contemporary minimally invasive approaches applied in the management of such stones were evaluated and compared. The cohort consisted of 561 male (60%) and 374 female (40%) patients. Of the 935 patients with medium-sized renal calculi, 535 (57.2%) were treated with shockwave lithotripsy (SWL), 201 (21.4%) with retrograde intrarenal surgery (RIRS), 110 (11.7%) with minimally invasive percutaneous nephrolithotomy (miniperc), and the remaining 89 (11.7%) patients with micropercutaneous nephrolithotomy (microperc). In the SWL group, stones were located mostly in the pelvis (51%), while in the miniperc and microperc groups, they were located mainly in the lower pole (46%, 53%, respectively). Stone-free rates after a single session were 77.2%, 86.1%, 88.8%, and 83.6% in the SWL, RIRS, microperc, and miniperc groups, respectively. Although no serious complications (above Clavien level III) were noted in any of the groups evaluated, Clavien I to II complications were common in the miniperc group. Although SWL is the preferred treatment option for patients with medium-sized (10-20 mm) renal stones, endourologic methods also have been found to have a significant role. Relatively lower complication rates along with higher stone-free status observed with the RIRS technique compared with percutaneous approaches have made this method a valuable option in the management of such stones in recent years.

One of the world`s first 500 kW turbines was installed in 1989 in the Netherlands. This forerunner of the current NedWind 500 kW range also represents the earliest predesign of the NedWind megawatt turbine. After the first 500 kW turbines with steel rotor blades and rotor diameter of 34 m, several design modifications followed, e.g. the rotor diameter was increased to 35 m and a tip brake was added. Later polyester blades were introduced and the rotor diameter was increased with 5 in. The drive train was also redesigned. Improvements on the 500 kW turbine concept has resulted in decreased cost, whereas annual energy output has increased to approx. 1.3 million kWh. Wind energy can substantially contribute to electricity supply. Maximum output in kiloWatthours is the target. Further improvement of the existing technology and implementation of flexible components may well prove to be a way to increase energy output, not only in medium or large sized wind turbines. 7 figs.

Full Text Available Ocean colour remote sensing is used as a tool to detect phytoplankton size classes (PSCs. In this study, the Medium Resolution Imaging Spectrometer (MERIS, Moderate Resolution Imaging Spectroradiometer (MODIS, and Sea-viewing Wide Field-of-view Sensor (SeaWiFS phytoplankton size classes (PSCs products were compared with in-situ High Performance Liquid Chromatography (HPLC data for the South China Sea (SCS, collected from August 2006 to September 2011. Four algorithms were evaluated to determine their ability to detect three phytoplankton size classes. Chlorophyll-a (Chl-a and absorption spectra of phytoplankton (aph(λ were also measured to help understand PSC’s algorithm performance. Results show that the three abundance-based approaches performed better than the inherent optical property (IOP-based approach in the SCS. The size detection of microplankton and picoplankton was generally better than that of nanoplankton. A three-component model was recommended to produce maps of surface PSCs in the SCS. For the IOP-based approach, satellite retrievals of inherent optical properties and the PSCs algorithm both have impacts on inversion accuracy. However, for abundance-based approaches, the selection of the PSCs algorithm seems to be more critical, owing to low uncertainty in satellite Chl-a input data

Full Text Available We live in a complex world and managers of organizations are constantly facing numerous challenges. Good decisions, i.e., better outcomes for organizations, require use of the powerful discipline Operational Research (OR/Management Science (MS. Organizations applying this discipline have achieved significant benefits such as cost reduction, increased revenues, increased market share, higher quality, improved productivity, improved performance, better customer service, etc. The aim of this paper is to examine whether managers of micro, small and medium-sized enterprises in Macedonia use OR models for supporting decision-making processes, where OR models, methods and techniques are commonly used, and what benefits achieved in using quantitative OR models, methods and techniques. The survey was conducted using a questionnaire distributed electronically to 100 managers of micro, 100 managers of small and 100 managers of medium-sized enterprises. The questionnaires were answered completely by 93 managers of the micro, 73 managers of the small and 71 managers of the medium-sized enterprises, and the questionnaire responses were subsequently analyzed. The answers showed that decisions on running enterprises are made intuitively by 90% of managers of the micro, 78% of managers of the small, and 55% of managers of the medium-sized enterprises, while quantitative OR models for supporting the decision-making process are used by 10% of managers of the micro, 22% of managers of the small, and 45% of managers of the medium-sized enterprises. Applied in the micro, small and medium-sized enterprises are inventory models, time series analysis and forecasting, whereas micro and medium-sized enterprises rely on decision analysis. Small and medium-sized enterprises use break-even analysis, assignation, linear programming, and project management. The OR models and methods used in running the respective enterprises led to the following results: optimal inventory

This paper presents the results of on-site interviews with representatives of 23 investor-owned utilities and 3 publicly-owned utilities. The purpose of the interviews was to obtain information on utilities' attitudes towards small and medium-sized power plants and towards building new nuclear plants in general. Most of the utilities interviewed preferred power plants smaller than the ones currently being offered, as long as the smaller plants did not incur a major economic penalty. However, according to the utilities interviewed, without changes in the current environment it is unlikely that there will be a significant market for new nuclear plants of any size. A trend in the utility industry towards generating companies appears to be a positive step. (orig.)

2016-05-01

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.

Full Text Available Orientation: Customer relationship management (CRM is important to organisations striving for competitive advantage through building relationships with their customers. Research purpose: This study identified the factors preceding CRM and assessed selected South African small- and medium-sized tourism enterprises’ (SMTEs readiness for CRM. Motivation: CRM is likely to enhance SMTEs’ competitiveness. However, successful adoption and implementation of CRM is unlikely unless the organisation is ready for it. Research design, approach and method: A quantitative research approach and survey questionnaire yielded primary data from 332 respondent organisations selected by systematic sampling. Exploratory factor analysis was used to identify the latent factors preceding CRM readiness. Organisational CRM readiness was assessed based on CRM maturity in terms of data collection, use and sharing throughout the organisation. Main findings: Respondent-organisations performed well on the four factors preceding CRM readiness − business strategy, customer strategy, touch points and competencies, skills and technology and also on data collections and use, but not on data sharing. Practical/Managerial implications: CRM practice is believed to assist organisations in tailoring products and services to customers’ needs, providing customer satisfaction, enhancing customer retention and ultimately improving the organisation’s competitiveness and profitability. CRM might fail if SMTEs do not have CRM-enabling conditions in place and a CRM readiness audit should therefore be performed. Contribution: The study contributes to a largely under-researched area concerning CRM in SMTEs by providing an improved understanding of the factors that will enable SMTEs to engage in CRM activities.

Highlights: • Colloidal aluminum- and titanium-based nanoparticles fabricated by laser ablation. • Various liquid environments and laser fluences were applied as variable parameters. • Physical characteristics of liquid medium influence ablation process and nanoparticle formation. • Size properties of prepared nanoparticles depend on liquid medium and laser fluence. • Ablation of both metals in ethanol results in nanoparticles with smaller size. - Abstract: In this paper, pulsed laser ablation method was used for synthesis of colloidal nanoparticles of aluminum and titanium targets in distilled water, ethanol, and acetone as liquid environments. Ultraviolet–visible (UV–vis) absorption spectrophotometer and scanning electron microscope (SEM) were used for characterization of produced nanoparticles. Using image processing technique and analyzing the SEM images, nanoparticles’ mean size and size distribution were achieved. The results show that liquid medium has strong effect on size properties of produced nanoparticles. From the results, it was found that ablation of both metal targets in ethanol medium leads to formation of smaller size nanoparticles with narrower size distributions. The influence of laser fluence was also investigated. According to the results, higher laser fluence produces larger mean size nanoparticles with broader size distribution

Full Text Available Modern organizations have raised a need to actively and quickly react to the changes in external business environment, as well as in internal processes considering not only the present situation, but also evaluating possible changes and forecasting the future. Enterprise risk assessment and management, which is strongly related with foreseeing the uncertain future, becomes topical not only scientifically, but also practically seeking to reveal new and unique solutions. Operational risk management in small and medium enterprises, creating the largest part of value added in the whole European Union, demands a separate attention and coordinated decisions and means. The objective of the paper – to analyse the process of enterprise risk management in small and medium-sized enterprises, as well as to propose adequate risk management solutions for these companies. After performing a research, it was found out that small and medium enterprises more than big organizations require a risk management strategy and methodology, need to distinguish activity objectives and events influencing them, and they can efficiently apply a risk portfolio method to manage risk. In small and medium enterprises it is recommended to incorporate a risk management system based on COSO ERM model that can be modified depending on company needs and possibilities, turning it into less formal and structured and easily applicable.

A deployable mechanism concept for the collection of small-to-medium-size space debris

Science.gov (United States)

St-Onge, David; Sharf, Inna; Sagnières, Luc; Gosselin, Clément

2018-03-01

Current efforts in active debris removal strategies and mission planning focus on removing the largest, most massive debris. It can be argued, however, that small untrackable debris, specifically those smaller than 5 cm in size, also pose a serious threat. In this work, we propose and analyze a mission to sweep the most crowded Low Earth Orbit with a large cupola device to remove small-to-medium-size debris. The cupola consists of a deployable mechanism expanding more than 25 times its storage size to extend a membrane covering its surface. The membrane is sufficiently stiff to capture most small debris and to slow down the medium-size objects, thus accelerating their fall. An overview of the design of a belt-driven rigid-link mechanism proposed to support the collecting cupola surface is presented, based on our previous work. Because of its large size, the cupola will be subject to significant aerodynamic drag; thus, orbit maintenance analysis is carried out using the DTM-2013 atmospheric density model and it predicts feasible requirements. While in operation, the device will also be subject to numerous hyper-velocity impacts which may significantly perturb its orientation from the desired attitude for debris collection. Thus, another important feature of the proposed debris removal device is a distributed array of flywheels mounted on the cupola for reorienting and stabilizing its attitude during the mission. Analysis using a stochastic modeling framework for hyper-velocity impacts demonstrates that three-axes attitude stabilization is achievable with the flywheels array. MASTER-2009 software is employed to provide relevant data for all debris related estimates, including the debris fluxes for the baseline mission design and for assessment of its expected performance. Space debris removal is a high priority for ensuring sustainability of space and continual launch and operation of man-made space assets. This manuscript presents the first analysis of a small-to-medium

Job Stress in the United Kingdom: Are Small and Medium-Sized Enterprises and Large Enterprises Different?

Science.gov (United States)

Lai, Yanqing; Saridakis, George; Blackburn, Robert

2015-08-01

This paper examines the relationships between firm size and employees' experience of work stress. We used a matched employer-employee dataset (Workplace Employment Relations Survey 2011) that comprises of 7182 employees from 1210 private organizations in the United Kingdom. Initially, we find that employees in small and medium-sized enterprises experience lower level of overall job stress than those in large enterprises, although the effect disappears when we control for individual and organizational characteristics in the model. We also find that quantitative work overload, job insecurity and poor promotion opportunities, good work relationships and poor communication are strongly associated with job stress in the small and medium-sized enterprises, whereas qualitative work overload, poor job autonomy and employee engagements are more related with larger enterprises. Hence, our estimates show that the association and magnitude of estimated effects differ significantly by enterprise size. Copyright © 2013 John Wiley & Sons, Ltd.

Average enterprises in these indicators have 6,4 %, 62,0 % and 54,8 % respectively. The statistical and economic analysis of the structure of small enterprises by types of economic activity, by indicators of the number of registered enterprises, and by the volumes of sold products is carried out. The uniformity of the distribution is estimated using the index of the concentration coefficient. The indicators of revenues to budgets of different levels from small and medium-sized businesses are set. The paper presents and summarizes the

Challenges and Considerations for Innovative Small and Medium Sized Reactors

International Nuclear Information System (INIS)

Kuznetsov, V.

2008-01-01

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

Improving market access opportunities for urban small, medium and micro-enterprises in South Africa

Directory of Open Access Journals (Sweden)

Christian M. Rogerson

2013-01-01

Full Text Available Since the democratic transition of 1994, the promotion of the small, medium and micro-enterprise (SMME economy has been a core focus of South African government policy. With high levels of unemployment and poverty in urban areas, the impact of this policy intervention is most critical for city development. Given South Africa’s chequered history, the national government’s focus is on transforming the prospects for enterprises owned by black South Africans, who were disadvantaged under apartheid. This article examines the range of contemporary policy initiatives to address business constraints on market access and catalyse new market opportunities for black-owned enterprises in urban South Africa. The article concentrates on two themes: 1 building links into private sector supply chains, especially through supplier diversity, and 2 building links into public sector markets through public procurement. It is shown that current policy directions recognise that the national government has a limited capacity to implement SMME improvement and build competitive black-owned SMMEs by itself, which has prompted support for private sector initiatives. In addition, the government is struggling to practice what it preaches and use its own procurement capacity to assist black-owned SMMEs.

2014-01-01

In China, for small and medium-sized cities, urban and rural planning management should play an important role during the process of urbanization. However, it failed to do that in reality due to a series of limits, such as local fiscal deficiency, scarce human resources, incomplete management systems, historic planning defects, inadequate supervisions, and imperfect regulations, etc. This paper made a comprehensive analysis on the dilemma of urban and rural planning management in China’s small and medium-sized cities and the interests and status of the government, enterprises and public in space resource allocation and put forward the methods to improve the quality of planning management in China’s small and medium-sized cities from the view of systems and mechanisms.

[Role of medium-sized independent laboratories in control of healthcare-associated infection].

Science.gov (United States)

Anzai, Eiko; Fukui, Toru

2009-05-01

In 2006, the Ministry of Health and Welfare revised the regulations regarding the Medical Service Law. The amendments stipulate that all healthcare institutions are required to implement infection control programs. However, small hospitals and clinics have no clinical microbiology laboratories, whereas medium-sized hospitals have few medical technologists and the outsourcing of microbiology tests to independent laboratories is common. The decreasing number of laboratories and recent outsourcing tendency reflect the increasing commercialization, and, with it, the escalating number of commercially operating chains. Each independent laboratory is responsible for supporting activities related to the surveillance, control, and prevention of healthcare-associated infections in the associated small and medium-sized hospitals. The people responsible for infection control in these hospitals usually do not have a background in microbiology. The evaluation of communication between independent laboratory staff and hospital personnel, and rapid turnaround time of microbiology laboratory test reports are important elements ensuring the quality of independent laboratory work. With the pressures of financial constraints in the Japanese medical insurance system, the development of a cost-effective and practical protocol for quality assurance is a real dilemma.

Two kinds of health questionnaires, the Todai Health Index (THI) and Cumulative Fatigue Index (CFI), were applied as a screening device for health management of workers belonging to small-medium sized enterprises. A total of 495 workers composed of 452 male workers of a glass-bottle manufacturing factory and 43 male workers of a soft-drink bottling factory were the subjects of the present study. It was found that the two kinds of health questionnaires were different from each other and have their own characteristics. Twelve scales of THI were grouped into two, the first consisting of ten scales (SUSY, RESP, EYSK, MOUT, DIGE, IMPU, MENT, DEPR, NERV, and LIFE) and the second consisting of two scales (AGGR and LISC). Nine categories of CFI were grouped into one by using principal factor analysis. It was confirmed that the twelve scale scores of THI obtained at small-medium sized factories differed from those scale scores of a reference group investigated at a large-sized enterprise. It is on the basis of the scales of aggressiveness and lies and also of the scale of mental unstability which characterizes workers, locality, job (clerical or field work), and size of industry (large or small sized) that the difference could be evaluated. Urban life characterized by a life style of staying up late at night and waking up late in the morning has been reflected on the scale of life irregularity. Irregularity of life induced by transformation of working schedule, such as two or three shifts of work and overtime, was also reflected on this scale. Two scales of THI test, i.e., many subjective symptoms and digestive organ complaints, seemed to be the representative scales indicating a close relation between work load and health level. The discriminant score for diagnosis of psychosomatic diseases is considered to be one of the most useful assessments of the individual's health condition. As mentioned above, THI is recommended as a convenient assessment method for health

Full Text Available This paper presents the geo-referenced acoustical results obtained throughout the close proximity noise (CPX technique carried out on different urban sections included within the 2017 strategic noise mapping (Directive 2002/49/CE in Ciudad Real, a Spanish medium-sized city. The employed methodology quantifies the tire/pavement noise generated in the contact between the tire and the surface of the studied sections. Measurements were carried out in different research campaigns between 2008 and 2015 (medium-term evolution. They give valuable information about the pavement-aging effect on its surface characteristics. Throughout these years, the acoustic situation of these sections has worsened mainly due to surface damage and higher mean profile depth (MPD values, although the performance does not follow the same pattern in every section. The relationships between measured tire/pavement noise and theoretical environmental noise, just due to the geometric spreading of sound energy, is also studied in order to elaborate a simple rolling noise mapping and to assess the environmental noise evolution. Traffic noise plays the main role in the noise registered within the assessed sections, therefore, CPX assessment could be used by local authorities to take decisions regarding urban planning and traffic management, with the aim of reducing noise exposure from traffic.

Full Text Available Along with marketing, small and medium enterprises (SMEs are commonly associated in literature with relationship marketing which results in marketing networks. This paper examines the specific characteristics that differentiate large companies from small and medium-sized enterprises, and the reasons that prevent SMEs from engaging in traditional marketing within the scope of marketing mix. The paper also shows that the key characteristic which distinguishes small from large companies is a prominent role of owner/managers. The owner/manager affects marketing of SMEs by creating his or her own personal networks with stakeholders in the environment, and considers it an important strategic focus and a factor that increases the performance of marketing decision-making. After a thorough review of secondary data sources this paper examines relationship marketing as a marketing framework for SMEs and, finally, proves that relationship marketing is more appropriate for SMEs than are traditional marketing concepts, that relationship marketing and network marketing create an important framework for SMEs and that there is a link between relationship marketing, personal networks and SMEs.

Full Text Available Background: Increasing competitiveness in the market, customer expectations related to the shortening of the deadlines and the reduction of prices of products and services force companies to improve the efficiency of internal processes. The integration of planning process is one of possible ways to achieve this aim. The integration of planning processes by the use of SOP model (Sales and Operations Planning is a method to implement this idea. The study allowed to identify ways to implement the process of sales and operations planning in small and medium-sized enterprises. Material and methods: The study was conducted in companies from different industries. The research method was in-depth interviews conducted with managers of companies or persons occupying management positions in the organizational process of implementing sales and operations planning. Results: During the survey, 10 companies were asked about the use of sales and operations planning, its elements and organizational aspects of its development, by the company. Conclusions: The use of sales and operations plan is closely dependent on the size of the company and its localization in the supply chain. Small enterprises are not interested in the integration of the planning process due to the small scale of operations and the centralization of decision-making process. Medium-sized enterprises, due to the increased complexity of the processes of planning, see the benefits of their integration in the SOP model.

OBJECTIVE To describe the meals consumed by adults living in a midsize city in the South of Brazil, according to the place and preparation. METHODS A population-based cross-sectional study was conducted in Pelotas, Southern Brazil, in 2012. The two-stage sampling design used the 2010 census tracts as primary sampling units. Data were collected on the place of meals (at home or out) and on the kind of preparations consumed at home (homemade, snacks, take away food) covering the two days prior to the interview, using a standardized questionnaire. RESULTS The study included 2,927 adults, of which 59.0% were female, 60.0% were below 50 years of age and 58.0% were in work. Data were collected on 11,581 meals consumed on the two days preceding the interview, 25.0% were consumed outside of the home at lunchtime, and 10.0% at dinnertime. Considering home meals, most participants reported eating food prepared at home at both lunch and dinner. The majority of out-of-home meals (64.0% for lunch and 61.0% for dinner) were consumed in the work place, mostly based on food prepared at home. Individuals eating out of home were mostly male, young and highly educated. The occupational categories that ate at restaurants more often were trade workers, businessmen, teachers and graduate professionals. CONCLUSIONS Despite the changes in eating patterns described in Brazil in recent years, residents of medium-sized towns still mostly eat at home, consuming homemade food. PMID:24789639

Investigating power factor compensation capacity calculation in medium sized industry

International Nuclear Information System (INIS)

Chudhry, M.A.; Hanif, A.

2008-01-01

There are a variety of techniques developed in order to improve the efficiency of electrical systems and reduce cost of providing electricity to the consumer. This paper presents a new technique for power-factor capacity calculation in medium-sized industrial/ commercial setups. Various loads of similar nominal power-factor are categorized and demand-factor of loads is so selected that it has engineering justifications. The developed system works on the principle of low-voltage power-factor correction, which substantially reduces electricity bill and increases loading-capacity of the electrical system. It allows commercial and industrial consumers to save on their power cost appreciably. This work utilizes software, which takes few inputs and produces numerous useful results. Adoption of this system can help the user in computing compensation-capacity, system KVA (size of transformer) and cost of compensation. A feature of this system is prediction of low PF penalty. Moreover, it also suggests the tentative payback period. (author)

The role of small and medium-sized reactors

International Nuclear Information System (INIS)

Kupitz, J.; Mourogov, V.

1999-01-01

The second half of the twentieth century has seen nuclear power evolve from the research and development environment to an industry that supplies 17% of the world's electricity. The past decade, however, has seen stagnation in nuclear power plant construction in the Western industrialized world, slow nuclear power growth in Eastern Europe and expansion only in East Asia. But the turn of the century is potentially a turning-point for nuclear power because of: increasing world energy consumption, with nuclear power's contribution to reducing greenhouse gas emissions, nuclear fuel resources sustainability, and improvements in operation of current nuclear power plants; advanced reactor designs that will improve economics and availability, and further enhance safety; and continued strengthening of the nuclear power safeguards system. This paper looks at the role that small and medium-sized reactors can play in an increasingly competitive global energy market, particularly with regard to maintaining a sustainable mix of energy sources.

Full Text Available Rockfill dams are mostly constructed using blasted rockfill materials obtained by blasting rocks or alluvial rockfill materials collected from the riverbeds. Behaviors of rockfill materials and their characterization significantly depend on breakage factor observed during triaxial loading. In this paper, two modeled rockfill materials are investigated by using medium triaxial cell. Drained triaxial tests are conducted on various sizes of modeled rockfill materials used in the two dams, and test data are analyzed accordingly. Breakage factor of rockfill material is studied and the effects of particle size and confining pressure on breakage factor are investigated using medium triaxial cell as many researchers have already conducted investigation using large triaxial cell.

In nuclear power generation, the development of large reactors has been promoted as the main energy source in Japan. However, world economy entered low growth age, and the growth of electric power demand slowed down. Accordingly, attention has been paid to the medium and small reactors that can cope with whatever needs by serializing their types in addition to the nuclear power plants of medium output matching to electric power demand. In order to cope with these new needs, the economical efficiency of medium and small reactors must be as close as possible to that of large reactors, and as the countermeasures to the demerits due to small size, those must be made into the plants having simplified systems and the safety easily acceptable to public. Hitachi Ltd. plans to develop the natural circulation type medium and small BWRs of 600 NWe output class, HSBWR-600, on the basis of the nuclear power plant technology based on the rich results of design and operation of BWRs obtained so far, and to rank them as one of the BWR series. The target of their development design, the circumstance of their development, the core design and the thermo-hydraulic characteristics, the reactor pressure vessel and in-core structures, the safety design, system design, building layout and the evaluation are reported.

2012-01-01

Full Text Available Small and medium sized enterprises have very important position in the EU economy, mainly in the area of growth and employment. However, most of SMEs are active only in their home country and only a few of them participate in cross-border activities. Furthermore, their activities in the internal market are limited by great deal of obstacles, mainly in the form of different tax systems which generate excessive compliance costs of taxation and the existence of different SMEs definitions for various purposes in Member states. In addition, from the view of the international taxation issues, the most important obstacles can be considered a transfer pricing and cross-border loss compensations. In this area, SMEs are facing specific problems and have specific needs. The aim of the paper is to analyze and evaluate the specific transfer pricing issues of SMEs and propose recommendations for them.

Revisiting the Economic Factors which Influence Fast Food South African Small, Medium and Micro Enterprise Sustainability

Directory of Open Access Journals (Sweden)

Bruce MASAMA

2018-03-01

Full Text Available In order to stimulate both developing economies and developed economies around the globe policy makers have, over the years, focused their attention to Small, Medium and Micro Enterprises (SMMEs. These business entities are often regarded as the lifeblood of economies around the globe however SMMEs are reported to have high failure rates. For example, in a South African dispensation, the failure rate of SMMEs is considered to be among the worst in the world as approximately 75% fail within a period of 42 months after opening. Through research in the early-2000s, the cause of the excessive South African SMMEs failure rate has been pinned on a plethora of micro-economic factors and macro-economic factors. Over the years the list of economic factors which adversely influence the sustainability of South African SMMEs have not changed drastically, which may well probably explain the high failure rate of these business entities in more recent times. Thus, for this paper, empirical research was conducted to ascertain the extent to which 24 economic factors adversely influence the sustainability of South African SMMEs. Quantitative data were obtained from 116 members of management of South African SMMEs and stemming from the results, it was found that these economic factors still have a reasonable adverse influence on the sustainability of these business entities.

One possibility to reduce CO 2 emissions is the application of photovoltaics (PV). This form of current generation is inexhaustible. It involves hardly any risks and can be disposed of at random. But what kind of potential do photovoltaics have? The disadvantages like low energy density, fluctuating availability and high costs are well known. What conclusions can thus be drawn for the future role of photovoltaics? The authors discuss these questions at the example of a medium-size German city and describe the main influencing factors for the future development. (orig.) [de

2002-12-01

Full Text Available The Greater Addo Elephant National Park project (GAENP involves the establishment of a mega biodiversity reserve in the Eastern Cape, South Africa. Conservation planning in the GAENP planning domain requires systematic information on the potential distributions and estimated spatial requirements, and population sizes of the medium to largesized mammals. The potential distribution of each species is based on a combination of literature survey, a review of their ecological requirements, and consultation with conservation scientists and managers. Spatial requirements were estimated within 21 Mammal Habitat Classes derived from 43 Land Classes delineated by expert-based vegetation and river mapping procedures. These estimates were derived from spreadsheet models based on forage availability estimates and the metabolic requirements of the respective mammal species, and that incorporate modifications of the agriculture-based Large Stock Unit approach. The potential population size of each species was calculated by multiplying its density estimate with the area of suitable habitat. Population sizes were calculated for pristine, or near pristine, habitats alone, and then for these habitats together with potentially restorable habitats for two park planning domain scenarios. These data will enable (a the measurement of the effectiveness of the GAENP in achieving predetermined demographic, genetic and evolutionary targets for mammals that can potentially occur in selected park sizes and configurations, (b decisions regarding acquisition of additional land to achieve these targets to be informed, (c the identification of species for which targets can only be met through metapopulation management,(d park managers to be guided regarding the re-introduction of appropriate species, and (e the application of realistic stocking rates. Where possible, the model predictions were tested by comparison with empirical data, which in general corroborated the

The etiology of hydrocephalus associated with the small- to medium-sized vestibular schwannomas is still controversial. We investigated tumor-specific factors related to the association of hydrocephalus with small- to medium-sized vestibular schwannomas. Among the 77 patients with vestibular schwannoma smaller than 30 mm, 9 patients demonstrated associated communicating hydrocephalus. Patient medical records, radiologic data, and histopathologic specimens were reviewed retrospectively. The age of the patients, and size, mean apparent diffusion coefficient (ADC) value, and histologic features of the tumors were compared with those of patients without hydrocephalus. The symptoms related to hydrocephalus improved in all patients after tumor removal. Both the mean size and ADC values exhibited a statistically significant difference between the tumors with and without hydrocephalus (P hydrocephalus. The increased tumor ADC value was considered to be the result of degenerative change and suggested the involvement of protein sloughing in the etiology of the associated hydrocephalus.

2012-01-01

Highlights: ► We model the IRIS reactor in RELAP5 and VIPRE codes. ► We use Printed Circuit Heat Exchangers and internally and externally cooled fuel pins in IRIS. ► We increase the IRIS power by 50% and demonstrate adequate safety performance. ► We show significant potential gain in economics for any integral PWR reactor design. - Abstract: Integral reactors have been proposed in recent years as a means to eliminate loss of coolant events, and reduce the number of large vessels of a nuclear power plant. In this paper the focus on how to further increase the power that can be derived from a given vessel volume. The example is applied to the International Reactor Innovative and Secure (IRIS), a medium size, light water reactor rated at 1000 MWt. The IRIS is an integral design containing all pumps and steam generators along with a traditional PWR core inside the reactor vessel. IRIS was designed with 8 Once-Through Helically Coiled Steam Generators (OTHSG), located above the core, in an annular region between the riser and the pressure vessel wall. This work examines ideas to increase its power output in the same vessel size while maintaining or improving the safety margins. The combination of Printed Circuit Heat Exchangers (PCHE) and Internally and EXternally cooled Annular Fuel (IXAF) is proposed to implement such improvement in otherwise the reference IRIS design. Safety implications of such steam generator and fuel design changes for the same reactor size are examined, under both steady state and transients, using the RELAP5 and VIPRE codes. It is found that the IRIS reactor power can be increased by 50% by using the PCHE and IXAF. The proposed design is found to be less expensive per unit electric power produced, these improvements and analyses can be applied to any integral reactor design.

Supply chain challenges in the South African automotive sector: do location, size and age matter?

2013-11-01

Full Text Available The South African automotive industry makes an important contribution to the South African economy. However, there are deficiencies within the local automotive component manufacturers’ (ACMs supplier base and therefore automotive assemblers, or original equipment manufacturers (OEMs, have to import many of their parts requirements. These deficiencies are caused by ACMs’ lack of technology, global supply capability, cost competitiveness and their geographic location (ACMs are scattered across the country. A study was conducted to explore the supply chain challenges South African ACMs face and whether the location, size and age of participating ACMs have a bearing on whether they face the same challenges. The results revealed that the most significant supply chain challenges in South Africa were in the customer relationship category. From the hypotheses testing, the conclusion could be drawn that, in general, participating ACMs face common supply chain challenges, irrespective of their location, age and size.This article contributes to the published research on the topic and the findings reveal that business opportunities in the automotive industry exist for entrepreneurs aspiring to enter into the automotive component industry.

Rapid preparation of ceramic moulds for medium-sized superalloy castings with magnesia-phosphate-bonded bauxite-mullite investments

2010-11-01

Full Text Available Phosphate-bonded investments have already been widely utilized in dental restoration and micro-casting of artistic products for its outstanding rapid setting and high strength. However, the rapid setting rate of investment slurry has up to now been a barrier to extend the use of such slurry in preparation of medium-sized ceramic moulds. This paper proposes a new process of rapid fabrication of magnesia-phosphate-bonded investment ceramic moulds for medium-sized superalloy castings utilizing bauxite and mullite as refractory aggregates. In order to determine the properties of magnesia-phosphate-bonded bauxite-mullite investments (MPBBMI, a series of experiments were conducted, including modification of the workable time of slurry by liquid(mL/powder(g(L/P ratio and addition of boric acid as retard agent and sodium tri-polyphosphate (STP as strengthening agent, and adjustment of bauxite (g/mullite(g(B/M ratio for mechanical strength. Mechanical vibration was applied to improve initial setting time and fluidity when pouring investment slurry; then an intermediate size ceramic mould for superalloy castings was manufactured by means of this rapid preparing process with MPBBMI material. The results showed that the MPBBMI slurry exhibits proper initial setting time and excellent fluidity when the L/P ratio is 0.64 and the boric acid content is 0.88wt.%. The fired specimens made from the MPBBMI material demonstrated adequate compression strength to withstand impact force of molten metal when the B/M ratio is 0.89 and the STP content is 0.92wt.%. The experimental results confirmed the feasibility of the proposed rapid fabricating process for medium-sized ceramic moulds with MPBBMI material by appropriate measures.

Full Text Available Abstract A set of changes in the competitive environment has recently provoked the emergence of a new kind of organization that has since its creation a meaningful share of its revenue being originated from international activities developed in more than one continent. Within this new reality, the internationalization of the firm in phases or according to its growth has resulted in it losing its capacity to explain this process with regard to small- and medium-sized enterprises (SME. Thus, in this paper, the international orientation (IO and export commitment (EC constructs have been revised under a theoretical context of the fast internationalization of medium-sized companies, so as to identify scales that more accurately measure these dimensions in the Brazilian setting. After a literature review and an exploratory research, the IO and EC scales proposed by Knight and Cavusgil (2004 and Shamsuddoha and Ali (2006 were respectively applied to a sample of 398 small- and medium-sized exporting Brazilian companies. In spite of conjunction and situation differences inherent to the Brazilian companies, the selected scales presented high measuring reliability. Furthermore, the field research outcomes provide evidence for the existence of a phenomenon of fast internationalization in medium-sized companies in Brazil, as well as support some theoretical assumptions of other empirical investigations carried out with samples from developed countries.

Manuel Alejandro Ibarra Cisneros

2017-01-01

Full Text Available The objective of this research is to determine the competitiveness level of the manufacturing small and medium-sized enterprises (SMEs of Baja California and to identify which areas within them affect this competitiveness. The methodology used is descriptive, correlational, and cross-sectional; the systemic competitiveness model is developed at the micro level, and a measurement instrument with 64 questions is used on 195 companies in the state; in addition, traditional multiple linear regressions are performed to test the hypotheses. One of the findings is that the SMEs in the state have a medium-low competitiveness level and do not show any relationship between the size of the companies and their competitiveness; however, the production-operations area prove to be more important for their competitiveness level. Although the measurement instrument that is used has no proportionality at the municipality and subsector level, it does allow us to approach the internal operation of the SMEs.

Giacomo Liotta

2012-11-01

Full Text Available On a daily basis, enterprises of all sizes cope with the turbulence and volatility of market demands, cost variability, and severe pressure from globally distributed competitors. Managing uncertainty about future demand requirements and volumes in supply-chain networks has become a priority. One of the ways to deal with uncertainty is the utilization of simulation techniques and tools, which provide greater predictability of decision-making outcomes. For example, simulation has been widely applied in decision-making processes related to global logistics and production networks at the strategic, tactical, and operational levels, where it is used to predict the impact of decisions before their implementation in complex and uncertain environments. Large enterprises are inclined to use simulation tools whereas small and medium-sized enterprises seem to underestimate its advantages. The objective of this article is to emphasize the relevance of simulation for the design and management of supply-chain networks from the perspective of small and medium-sized firms.

2017-01-01

Full Text Available Since the early 1980s Small, Medium and Micro Enterprises (SMMEs have been regarded as the driving forces of both developing and developed economies around the world. In a South African dispensation, SMMEs are responsible for adding imperative socio-economic value to the country, particularly in terms of eradicating poverty and diminishing unemployment levels. By doing so, these business entities are believed to contribute at least 50% to the national Gross Domestic Product. Albeit the aforementioned, previous research studies report that up to 75% of South African SMMEs fail after being in existence for only 42 months. Though the latter dispensation has been blamed on many economic factors, over the years the sustainability of South African SMMEs has not improved to a great extent. In order to provide insight on the latter dispensation, this literature review paper was conducted to ultimately formulate two hypotheses for further empirical testing.

It is often argued that the process of globalization has mainly favoured large-scale multinational companies which are able to organize their business efficiently within internal hierarchies. However, globalization has not only pushed cross-border intra-finn transactions but also other arrangements among firms such as licensing or subcontracting that fall short of ownership involvements. This opens up new opportunities for small and medium sized enterprises, too. The paper provides a general ...

A set of molecular dynamics simulations were performed to investigate the effect of cooling rate and system size on the medium-range structure of melt-derived multicomponent silicate glasses, represented by the quaternary 45S5 Bioglass composition. Given the significant impact of the glass degradation on applications of these materials in biomedicine and nuclear waste disposal, bulk structural features which directly affect the glass dissolution process are of particular interest. Connectivity of the silicate matrix, ion clustering and nanosegregation, distribution of ring and chain structural patterns represent critical features in this context, which can be directly extracted from the models. A key issue is represented by the effect of the computational approach on the corresponding glass models, especially in light of recent indications questioning the suitability of conventional MD approaches (that is, involving melt-and-quench of systems containing ∼10{sup 3} atoms at cooling rates of 5-10 K/ps) when applied to model these glasses. The analysis presented here compares MD models obtained with conventional and nonconventional cooling rates and system sizes, highlighting the trend and range of convergence of specific structural features in the medium range. The present results show that time-consuming computational approaches involving much lower cooling rates and/or significantly larger system sizes are in most cases not necessary in order to obtain a reliable description of the medium-range structure of multicomponent glasses. We identify the convergence range for specific properties and use them to discuss models of several glass compositions for which a possible influence of cooling-rate or size effects had been previously hypothesized. The trends highlighted here represent an important reference to obtain reliable models of multicomponent glasses and extract converged medium-range structural features which affect the glass degradation and thus their

Technically, nuclear reactors which produce energy in the form of heat can supply energy products other than electricity, including district heat, process heat, potable water etc. Currently non-civil uses of nuclear energy are very limited civil applications except for a military nuclear powered ship and an energy usage in isolated areas. However, the future global environment and an energy resources scarcity could promote a significant usage of non-electrical applications on an industrial scale. Considering these situations, this report analyzed the following: (1) Worldwide non-electrical application of a small and medium sized nuclear reactor - survey the situation of the current technical applications, - survey the global market potential estimation for various applications (2) Technical cooperation potential in several countries - identify necessary conditions for nuclear cooperation, - select candidate countries: Morocco, UAE, Indonesia, Chile and Vietnam, - survey the energy and water situation, - survey the legal and international regime infrastructure

Full Text Available In The European Union’s country members, small and medium-sized enterprises (SMEs play an essential role in economic life, having special features that make adaptation process to the contemporary economy easier. Small and medium sized enterprises (SMEs are the most dynamic and vital factor of progress in the contemporary society, main generator of economic performance and substance in any country, employment opportunity provider for most of population, major contributor to the national budget, and engine to improve the living standard of the population. SMEs represent 99% from all enterprises, drawing up the main human resources aglomeration. In the contemporary economic context, SMEs should act as learning entities, by developing the most important resources they own: the human resources. Human resource development (HRD has gained a permanent role within SMEs, agencies and nations, increasingly not only as an academic discipline, but as a central theme in development area. Being a combination of training and education, in a broad context of adequate human resource policies, HRD ensures the continual improvement and growth of both individual and organization.

Methodologies and Decision Criteria for Demonstrating Competitiveness of Small and Medium Sized Reactors - Present Value Capital Cost Model. Annex VIII

2013-12-15

Smaller size reactors are required to fulfil the growing energy needs of developing countries and emerging markets, as well as niche markets in developed countries. Grid appropriate reactors have been identified within the United States Department of Energy Global Nuclear Energy Partnership initiative as one of the key elements required to enable worldwide expansion of the peaceful use of nuclear power. In a speech at a conference in Algiers on 9 January 2007, the former IAEA Director General, Mohamed El Baradei, discussed the interest in new small and medium-size reactor designs which allow a more incremental investment than is required for a big reactor, and provide a better match to grid capacity in many developing countries'. Smaller size reactors (IAEA defines as 'small' those reactors with a power <300 MW(e) and 'medium' with a power <700 MW(e)) are the logical choice for smaller countries or those with a limited electrical grid. In fact, smaller reactors are now in different stages of development throughout the world, and interest in their deployment has also been expressed. With regards to decisions on the addition of power plant capacity, small reactors have many attractive characteristics, namely size, simplicity, enhanced safety, cost savings and lower financial resource requirements. On the downside, the specific costs of some components and systems of small and medium sized reactors (SMRs) may be higher as a result of economy of scale effects. This annex explores some of the factors affecting decisions on power plant capacity addition in world markets, focusing particularly on many of the characteristics of SMRs.

This paper summarises part of our on-going investigations on the possible introduction of nuclear energy in developing countries or countries with low capacity electrical grids. These investigations are principally concerned with future PWR developments and basically try to search for plausible and economic answers to the three difficult questions that each nuclear technology exporting country faces today: 1)- how to compensate the apparent loss of economic competitiveness, related to the scaling effect, of a small or medium sized reactor? 2)- how to reconcile the introduction of nuclear energy on the large scale with the two major preoccupations of nuclear safety and nuclear proliferation? 3)- how to demonstrate that the proposed concept(s) can effectively meet the safety objectives of the requirements for future reactors in Europe and in other countries?

Ramos, R. Soledad; Brea, Mariana; Kröhling, Daniela M.

2017-11-01

The main aim of the present paper is to describe the first Detarioideae fossil woods from El Palmar Formation (Late Pleistocene) in the Uruguay River Basin (Entre Ríos, Argentina). This study is based on five silicified wood specimens preserved in fluvial deposits, which were transported from their growth site. Two new genera and species are described: Paraoxystigma concordiensis gen. nov and sp. nov. has medium-sized vessels, paratracheal axial parenchyma, heterocellular and multiseriate rays, and diffuse axial canals similar in size and shape to vessels, and Gossweilerodendroxylon palmariensis gen. nov and sp. nov. has medium-sized vessels, alternate intervessel pits, paratracheal and apotracheal axial parenchyma, homocellular and uni to-multiseriate rays, and small diffuse axial canals. These Detarioideae fossil records in south-eastern South America support the existence of a very old relationship with the extant West African forests. Eco-anatomical features observed in these fossil woods, along with the climatic information available from the Nearest Living Relatives (NLRs) comparison, suggest warm and humid climatic conditions for the upper-middle basin of the Uruguay River during some periods of the Late Pleistocene.

Wildlife passages are widely used mitigation measures designed to reduce the adverse impacts of roads on animals. We investigated whether road kills of small and medium-sized terrestrial vertebrates can be reduced by constructing dry paths adjacent to streams that pass under road bridges. The study was carried out in southern Finland during the summer of 2008. We selected ten road bridges with dry paths and ten bridges without them, and an individual dry land reference site for each study bridge on the basis of landscape and traffic features. A total of 307 dead terrestrial vertebrates were identified during the ten-week study period. The presence of dry paths decreased the amount of road-killed terrestrial vertebrates (Poisson GLMM; p road-kills on mammals was not such clear. In the mammal model, a lack of dry paths increased the amount of carcasses (p = 0.001) whereas the number of casualties at dry path bridges was comparable with dry land reference sites. A direct comparison of the dead ratios suggests an average efficiency of 79% for the dry paths. When considering amphibians and mammals alone, the computed effectiveness was 88 and 70%, respectively. Our results demonstrate that dry paths under road bridges can effectively reduce road-kills of small and medium-sized terrestrial vertebrates, even without guiding fences. Dry paths seemed to especially benefit amphibians which are a threatened species group worldwide and known to suffer high traffic mortality. Copyright © 2014 Elsevier Ltd. All rights reserved.

Full Text Available Change is a constant in everyday life confronting organizations to continuously adapt their strategy, structure, processes, and culture in order to survive and stay competitive on the market. Implementing organizational change is one of the most important skills required for managers and in the meantime the most difficult one. The forces driving change within an organization, that can be either external or internal, are those that propel a company forward towards change and in order to identify the need for change and make the proper changes, managers have to develop a tool that allows them to analyze how does the environment influence their business activities. A vision for change will clarify the directions in which the organization needs to move, starting from its current state and taking in consideration the existing opportunities and threats from the environment that allow to move to a future desired state. The purpose of this paper is to identify the concern for change in the Romanian small and medium sized enterprises by presenting and explaining the past and present influences of the main external forces that have determined the need for change in the last 3-5 years and to make recommendations about future possible changes that have to be performed by managers for a better harmonization with the environment. The research method used for this study is the interview on a sample that contains some of the most relevant SME’s from the western side of Romania, from different industries. We analyzed the main external forces that had an impact on the small and medium sized enterprises and how were they generating the need for organizational change, in order to see which present and future changes are required.

Various stimuli to the dentin surface elicit dentinal pain by inducing dentinal fluid movement causing cellular deformation in odontoblasts. Although odontoblasts detect deformation by the activation of mechanosensitive ionic channels, it is still unclear whether odontoblasts are capable of establishing neurotransmission with myelinated A delta (Aδ) neurons. Additionally, it is still unclear whether these neurons evoke action potentials by neurotransmitters from odontoblasts to mediate sensory transduction in dentin. Thus, we investigated evoked inward currents and evoked action potentials form trigeminal ganglion (TG) neurons after odontoblast mechanical stimulation. We used patch clamp recordings to identify electrophysiological properties and record evoked responses in TG neurons. We classified TG cells into small-sized and medium-sized neurons. In both types of neurons, we observed voltage-dependent inward currents. The currents from medium-sized neurons showed fast inactivation kinetics. When mechanical stimuli were applied to odontoblasts, evoked inward currents were recorded from medium-sized neurons. Antagonists for the ionotropic adenosine triphosphate receptor (P2X 3 ), transient receptor potential channel subfamilies, and Piezo1 channel significantly inhibited these inward currents. Mechanical stimulation to odontoblasts also generated action potentials in the isolectin B 4 -negative medium-sized neurons. Action potentials in these isolectin B 4 -negative medium-sized neurons showed a short duration. Overall, electrophysiological properties of neurons indicate that the TG neurons with recorded evoked responses after odontoblast mechanical stimulation were myelinated Aδ neurons. Odontoblasts established neurotransmission with myelinated Aδ neurons via P2X 3 receptor activation. The results also indicated that mechanosensitive TRP/Piezo1 channels were functionally expressed in odontoblasts. The activation of P2X 3 receptors induced an action potential

Drivers for OSH interventions in small and medium-sized enterprises.

Cagno, Enrico; Masi, Donato; Leão, Celina Pinto

2016-01-01

The debate concerning occupational safety and health (OSH) interventions has recently focused on the need of improving the evaluation of interventions, and in particular on the need for providing information about why the intervention worked or not, under what circumstances and in which context. Key concepts in the analysis of the context are the drivers, i.e., those factors enabling, fostering or facilitating OSH interventions. However, the concept of driver for an OSH intervention is both confused and contested. Although the term is widely used, there is little consensus on how drivers should be understood, how important they are in different contexts and how they can facilitate interventions. This exploratory study based on interviews with the owner-managers and the safety officers of small and medium-sized enterprises (SMEs) gives an overview of the most characteristic drivers for OSH interventions. The results will be used to make an initial evaluation of SMEs' needs, and will help orient interventions and future research.

Full Text Available eLearning through its flexibility and facility of access is seen as a major enabler of lifelong learning (LLL, as a catalyst of change and a chance for small and medium-sized enterprises (SMEs to improve their business and to integrate into European market. But so far the eLearning in the context of vocational educational training has been mainly adopted by large enterprises, while only little activity can be observed in SMEs. The question arises what the chances and challenges for SMEs are and what is the experience with its usage. In this paper after a presentation of key issues in eLearning chances and challenges of eLearning for SMEs are discussed and experiences are exemplified by three EU-funded eLearning projects. The focus lies on the ongoing project ARIEL - Analysing and Reporting the Implementation of Electronic Learning in Europe - coordinated by the Institut Arbeit und Technik (IAT.

Fullerene-like cage structures of medium-sized (ZnO){sub n} clusters with n = 15 − 24 were generated by spiral algorithm and optimized using density functional theory calculations. Most of these lowest-energy cage structures contain only four-membered and six-membered rings, whereas eight-membered rings were found in the lowest-energy cages of (ZnO){sub n} (n = 19, 20, 23, 24). Our best cage configurations either reproduce or prevail the previously reported ones. The size-dependent electronic properties were also discussed.

Emission data is an essential tool for understanding environmental problems associated with sources and dynamics of air pollutants in urban environments, especially those emitted from vehicular sources. There is a lack of knowledge about the estimation of air pollutant emissions and particularly its spatial and temporal distribution in South America, mainly in medium-sized cities with population less than one million inhabitants. This work performed the spatial and temporal disaggregation of the on-road vehicle emission inventory (EI) in the medium-sized Andean city of Manizales, Colombia, with a spatial resolution of 1 km × 1 km and a temporal resolution of 1 h. A reported top-down methodology, based on the analysis of traffic flow levels and road network distribution, was applied. Results obtained allowed the identification of several hotspots of emission at the downtown zone and the residential and commercial area of Manizales. Downtown exhibited the highest percentage contribution of emissions normalized by its total area, with values equal to 6% and 5% of total CO and PM10 emissions per km2 respectively. These indexes were higher than those obtained in residential-commercial area with values of 2%/km2 for both pollutants. Temporal distribution showed strong relationship with driving patterns at rush hours, as well as an important influence of passenger cars and motorcycles in emissions of CO both at downtown and residential-commercial areas, and the impact of public transport in PM10 emissions in the residential-commercial zone. Considering that detailed information about traffic counts and road network distribution is not always available in medium-sized cities, this work compares other simplified top-down methods for spatially assessing the on-road vehicle EI. Results suggested that simplified methods could underestimate the spatial allocation of downtown emissions, a zone dominated by high traffic of vehicles. The comparison between simplified methods

Possible Future Role of Small and Medium Sized Reactors (SMRs) in Countries with Small and Medium Electricity Grids

International Nuclear Information System (INIS)

Alujevic, L.

2016-01-01

Small and Medium Sized Reactors (SMRs) could have enormous potential as options for enhancing the energy supply security, as well as providing a lower capital investment compared to conventional Nuclear Power Plants (NPPs). The trend in SMR development has been towards design certification of small modular reactors, defined as advanced reactors that produce electric power up to 300 MW(e), designed to be built in factories and shipped to utilities for installation as demand arises. The factory-built small modular reactors aim to reduce lengthy construction times while simultaneously increasing quality, thereby minimizing the costs associated with the current time for construction that spans 5 to 8 years. SMR designs include water-cooled reactors, high temperature gas cooled reactors, as well as liquid metal cooled reactors with fast neutron spectrum. Also, many are designed to be emplaced below ground level, giving a high resistance to terrorist threats. The projected timelines of readiness for deployment of SMRs generally range from the present to 2025 - 2030. Currently there are more than 45 SMR designs under development for different application issues. This paper will try to elaborate the benefits and drawbacks of SMRs, as well as describe a couple of designs. Furthermore, some timelines and cost estimates will be provided, depending on the data currently available. Taking all that into account, the conclusion will try to ascertain the suitability of SMRs for Countries with Small and Medium Electricity Grids, namely Croatia. (author).

2012-09-01

Full Text Available Between January 2007 and December 2010, the abundance of medium-sized mammals was studied, with special focus on the Molina's hog-nosed skunk, Conepatus chinga (Molina, 1782, at four locations in southern Brazil. In this study, transect line methodology was used to obtain data for Distance Analyses. Transects were traveled by car at night, searching with spotlights along the edges of secondary roads in agricultural landscapes. Along 1,811 km, we obtained 620 observations of 20 mammal species. The most common species was the exotic European hare, Lepus europaeus (Pallas, 1778; the highest abundance estimated for South America was observed in one of the study areas, where its density was estimated as 32 individuals/km². Carnivores were the most commonly recorded mammals, represented by 10 species and comprising 51% of all observations. Molina's hog-nosed skunk occurred in all study areas, but occurred in sufficient numbers to obtain density estimates in only two of the areas. We estimated 1.4 to 3.8 individuals/km², in the first density estimate made by the transect method for a member of Conepatus in the Neotropics. These values are similar to those estimated for North American species of Mephitidae. In Brazil, C. chinga is apparently more abundant in the Pampa biome than in the grasslands of the Atlantic Forest. For two other carnivores, Lycalopex gymnocercus (Fisher, 1814 and Cerdocyon thous (Linnaeus, 1766, we estimated preliminary densities that were similar to those previously cited for different regions.

Particle-size distribution modified effective medium theory and validation by magneto-dielectric Co-Ti substituted BaM ferrite composites

Li, Qifan; Chen, Yajie; Harris, Vincent G.

2018-05-01

This letter reports an extended effective medium theory (EMT) including particle-size distribution functions to maximize the magnetic properties of magneto-dielectric composites. It is experimentally verified by Co-Ti substituted barium ferrite (BaCoxTixFe12-2xO19)/wax composites with specifically designed particle-size distributions. In the form of an integral equation, the extended EMT formula essentially takes the size-dependent parameters of magnetic particle fillers into account. It predicts the effective permeability of magneto-dielectric composites with various particle-size distributions, indicating an optimal distribution for a population of magnetic particles. The improvement of the optimized effective permeability is significant concerning magnetic particles whose properties are strongly size dependent.

Tax-saving, Innovative Incentives for Small and Medium - Sized Enterprises in Hungary

Rita Ambrus

2012-06-01

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.

IMPACT OF INNOVATION UPON THE DYNAMICS OF ROMANIAN SMALL AND MEDIUM SIZED ENTERPRISES

2013-10-01

Full Text Available Innovation is central to economic growth, as the area in which it develops takes the whole sphere of economic activities: product, process, service, organization, marketing, hence the economic effects they may cause. Creating "innovative enterprises", giving tax cuts to certain periods of time, preferential loans, creating funds 'risk capital' are just some of the measures that European countries which already apply and Romania, willing to encourage innovation. The present paper presents two ways of exposing this issue, using theoretical sources but also real official data concerning the concept of innovation and also the ways of applying it within small and medium sized enterprises.

Is the Control Environment a Basis for Customised Risk Management Initiatives in South African Small, Medium and Micro Enterprises?

Directory of Open Access Journals (Sweden)

Juan-Pierré BRUWER

2016-11-01

Full Text Available Before the official recognition of Small, Medium and Micro Enterprises (SMMEs in South Africa during the mid-1990s, these business entities have been key players in the stimulation of the national economy. Albeit their socio-economic value added, prior research shows that the sustainability of these business are among the worst in the world, since approximately 70% of South African SMMEs fail within their first three years of existence. This dispensation is often blamed on inter alia, their inadequate management of economic factors which, in turn, cultivates risks. Notwithstanding the fact that most South African SMMEs make use of customised risk management initiatives, previous research shows that these initiatives are not deemed as adequate and/or effective to mitigate risks. Since the manner in which risks are managed are strongly dependent on the attitude and awareness of its management surrounding internal control (control environment, this study focused on investigating whether the control environment was used as foundation to implement their customised risk management initiatives. Empirical research was conducted whereby primary quantitative data were collected from respondents through the deployment of a questionnaire, through means of non-probability sampling methods. The results showed that though the control environments of South African SMMEs were regarded as good, they were not used as foundation by South African SMMEs to implement their customised risk management initiatives.

Factors that influence planning for physical activity among workers in small- and medium-sized enterprises

2018-06-01

Full Text Available Physical activity (PA is necessary for improving the health of workers in small- to medium-sized enterprises (SMEs. However, behavioral changes conducive to PA are often difficult to achieve despite intentions. Because intention to perform PA does not always translate to action, proper planning may be critical for achieving PA. In this study, we aimed to identify factors related to planning for PA among workers in SMEs because this is one population that has been identified as being at higher risk for lifestyle-related diseases in Japan. Participants completed a series of validated questionnaires. Of 353 valid responses, 226 individuals (149 men; aged 47.5 ± 8.7 years stated their intention to perform PA. Multiple regression analysis indicated that a higher PA planning score was significantly associated with higher self-efficacy for PA (p < 0.001, higher risk perception regarding inactivity (p = 0.012, and greater knowledge of information about PA community services (p = 0.019. Therefore, we recommend that self-efficacy, risk perception, and information regarding PA community services are enhanced in the daily working lives of workers at their workplaces. In this manner, they can promote their planning of health behavioral changes in a supportive environment, drawing upon available services, supports, and other resources.

Sustainability in Small and Medium-Sized Manufacturing Enterprises: An Empirical Study

Directory of Open Access Journals (Sweden)

I. Garbie

2016-06-01

Full Text Available The main goal of this paper is to analyze and investigate sustainable practices in small and medium-sized manufacturing enterprises (SMEs. A comprehensive analysis and a mathematical framework are used to assess the sustainability indexes (SDIs of each aspect/issue and pillar/dimension, and of the whole manufacturing enterprise. Sustainability in the whole manufacturing enterprise is represented by the sustainable development index (SDI. The results show that there is a significant difference in SDIs between aspects and dimensions, with economic sustainability representing the highest percentage in the SDI. Also, the results show that industrial companies are adopting sustainable practices and applying them to most of the issues/aspects of the dimensions, and they can direct manufacturing companies in the industrial sector to develop strategies for sustainability. This paper introduces a new understanding of the practices and implementation of sustainability/sustainable development by SMEs through assessing the SDIs.

Polyarteritis nodosa (PAN) is a systemic necrotizing vasculitis of medium-sized visceral vessels. However, cutaneous arteritis (CA) and gastrointestinal (GI) vasculitis are forms of single-organ vasculitis having indistinguishable histopathologic findings from PAN. The aim of this study was to evaluate and compare the clinical characteristics, treatment, and outcomes of patients with systemic PAN, CA, and GI vasculitis. Retrospective cohorts were assembled, consisting of patients with PAN, CA, and GI vasculitis between 1980 and 2014. The demographics, clinical characteristics, treatment, and outcomes of patients were abstracted from medical records. We included 48 patients with PAN, 41 patients with CA, and 19 patients with GI vasculitis. The disease of 1 patient evolved from CA to systemic PAN during the disease course. At diagnosis, 94% of patients with PAN, 93% of patients with CA, and 67% of patients with GI vasculitis were treated with glucocorticoids. Additional immunosuppressive agents were used in 67% of PAN, 37% of GI vasculitis, and 32% of CA cases. The 5-year cumulative relapse rate was 45.2% in CA, and only 9.6% in PAN during a followup of approximately 6 years. No deaths were observed in the CA group. The survival rate at 10 years was 66% in the PAN group and 61% in the GI vasculitis group. Systemic PAN, CA, and GI vasculitis take different clinical courses and therefore may be different diseases, rather than existing on a spectrum of the same disease. Progression of CA to systemic PAN is very rare. Relapse risk is low during followup in PAN. Patients with CA have a higher relapse rate than those with systemic PAN, possibly due to less use of immunosuppressive therapy in CA. © 2016, American College of Rheumatology.

Corporate social responsibility and small-medium sized enterprises: evidence from Greece

Directory of Open Access Journals (Sweden)

Electra Pitoska

2018-03-01

Full Text Available This paper is a qualitative empirical research of Greek Small and Medium-sized Enterprises (SMEs and examines their dominant perceptions and attitudes towards Corporate Social Responsibility (CSR. The research was conducted in the Region of Western Macedonia, North Greece, via personal interviews based on a structured questionnaire, which was completed by 420 enterprises, with different business functions, and were randomly chosen from local Chamber registers. The results demonstrated that, as Greek SMEs in the periphery have not decided on a particular strategy for Social Responsibility practices, CSR is frequently defined as sponsorship or charity programmes. The research also revealed the restraining factors for SMEs in implementing CSR policies: financial cost, small size of enterprises, absence of specialized partners, and poor supporting role of public authorities. Whereas, the most significant non-financial goals for the enterprises attempting to implement CSR in Greece are: responsibility and respect to customers, promotion of sustainability, environmentally-friendly practices; human resources and protection of rights are less emphasized. Interestingly, more than 80% of the subjects hold that engaging in CSR practices in the current financial context is vital. With regard to the benefits resulting from CSR, the research demonstrated that: Enhancing ‘corporate image’, ‘business performance’, and ‘customer satisfaction’ are significant. Nevertheless, the research highlighted that implementing CSR strategies are rather positively than strongly correlated with the benefits deriving from CSR.

Linking human capital and enterprise sustainability in Indonesian medium-sized food manufacturing enterprises: the role of informal knowledge sharing practice

Science.gov (United States)

Sunardi, O.

2017-12-01

Medium-sized food manufacturing enterprises in Indonesia are significant in a number of contexts, in terms of their part to the national production (GDP) and their establishment to the employment. In term of their role to national production, manufacturing sector contributes the highest GDP by 85%. In this sector, food manufacturing subsector contributes the highest GDP. Nevertheless, they faced the same common problems: quality of human capital and sustainability issues. Previous government supplementary programs have been established to expand the human capital capability amongst medium enterprises. Adequate amount of fund has been apportioned to develop human capital, though, the medium enterprises sustainability is still in question. This study proposes and examines the human capital role from informal knowledge sharing perspective. By conducting qualitative approach through interviews to four informants in Indonesian medium-sized food manufacturing enterprises, a set of hypotheses is derived from this study for future quantitative study. This study indicates that human capital traits (diverse education background, employee skills, and employee experience) could leverage the practice of informal knowledge sharing. Constructs such as mutual trust and reciprocal intention could play as mediating variables, and cultural interpretation perspective could act as moderating factor to informal knowledge sharing effectiveness. In final, informal knowledge sharing is indicated to play as moderating variable for human capital policy and practice to support enterprise sustainability.

Evaluation of the technical condition of medium-sized boilers

Directory of Open Access Journals (Sweden)

Lošák Pavel

2018-01-01

Full Text Available The recent trend in the steam and electricity production has been both to increase the efficiency of the facility and to keep tightening legislation concerning emission limits. The lifetime of energy equipment is greatly influenced by the operating temperature, pressure and operating characteristics. The new conditions lead the operator to more often changes of these parameters, which has negative influence to the facility in terms of service life. Precise knowledge of the facility being operated and the ability to predict the residual life of its key parts in time is therefore necessary. A new methodology for determining the residual life and evaluating problematic situations of medium size boilers was developed at Brno University of Technology. Its approaches and advantages will be presented in this paper. The methodology provides the user with approaches for the lifetime evaluation of an equipment as a whole, based on detailed knowledge of the equipment being investigated and the ongoing damage. Additionally, if the equipment is continuously evaluated, it is possible to extend the inspection interval or to achieve a significantly higher lifetime of the entire equipment, thereby reducing the economic cost. If defined criteria are met, the methodology also allows inclusion of FEM and CFD simulations for achieving higher relevance of the results.

Borrajo, M Lourdes; Baruque, Bruno; Corchado, Emilio; Bajo, Javier; Corchado, Juan M

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.

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.

In-beam evaluation of a fully-equipped medium-size 30$\\times$30 cm$^2$ Resistive Plate WELL (RPWELL) detector is presented. It consists here of a single element gas-avalanche multiplier with Semitron ESD225 resistive plate, 1 cm$^2$ readout pads and APV25/SRS electronics. Similarly to previous results with small detector prototypes, stable operation at high detection efficiency (>98%) and low average pad multiplicity (~1.2) were recorded with 150 GeV muon and high-rate pion beams, in Ne/(5%CH$_4$), Ar/(5%CH$_4$) and Ar/(7%CO$_2$). This is an important step towards the realization of robust detectors suitable for applications requiring large-area coverage; among them Digital Hadron Calorimetry.

Size Effects on Surface Elastic Waves in a Semi-Infinite Medium with Atomic Defect Generation

Directory of Open Access Journals (Sweden)

F. Mirzade

2013-01-01

Full Text Available The paper investigates small-scale effects on the Rayleigh-type surface wave propagation in an isotopic elastic half-space upon laser irradiation. Based on Eringen’s theory of nonlocal continuum mechanics, the basic equations of wave motion and laser-induced atomic defect dynamics are derived. Dispersion equation that governs the Rayleigh surface waves in the considered medium is derived and analyzed. Explicit expressions for phase velocity and attenuation (amplification coefficients which characterize surface waves are obtained. It is shown that if the generation rate is above the critical value, due to concentration-elastic instability, nanometer sized ordered concentration-strain structures on the surface or volume of solids arise. The spatial scale of these structures is proportional to the characteristic length of defect-atom interaction and increases with the increase of the temperature of the medium. The critical value of the pump parameter is directly proportional to recombination rate and inversely proportional to deformational potentials of defects.

There is some evidence that South Asian women may have an increased risk of osteoporosis compared with Caucasian women, although whether South Asians are at increased risk of fracture is not clear. It is unknown whether older South Asian women differ from Caucasian women in bone geometry. This is the first study, to the authors' knowledge, to use peripheral Quantitative Computed Tomography (pQCT) to measure radial and tibial bone geometry in postmenopausal South Asian women. In comparison to Caucasian women, Asian women had smaller bone size at the 4% (-18% pAsians had increased cortical thickness (-17% p=0.04) at the 38% tibia, (in proportion to bone size (-30% p=0.003)). Furthermore, at the 4% and 14% tibia there were increased total densities (+12% to +29% pAsians. These differences at the 14% and 38% (but not 4%) remained statistically significant after adjustment for Body Mass Index (BMI). These adaptations are similar to those seen previously in Chinese women. Asian women had reduced strength at the radius and tibia, evidenced by the 20-40% reduction in both polar Strength Strain Index (SSIp) and fracture load (under bending). Overall, the smaller bone size in South Asians is likely to be detrimental to bone strength, despite some adaptations in tibial cortical thickness and tibial and radial density which may partially compensate for this.

Full Text Available Logistics integration across partnering firms has become the backbone of supply chain management as it facilitates information sharing, which is required in order to enhance business performance. This study investigated the mediatory role of information sharing on the relationships between logistics integration and business performance within the small and medium enterprise (SME context. Five research hypotheses were postulated and the hypotheses were empirically tested using sample data from the SME sector in South Africa’s Gauteng Province. The results indicated that logistics integration positively influences information sharing and business performance in a significant way within the context of South African SMEs. Managerial implications of the findings are discussed, whilst limitations and future research directions are indicated.

Full Text Available Companies classified as small and medium-sized enterprises (SMEs account for a large proportion of Europe’s economic and professional activity. In practice, 99 % of business in the European Union are SMEs, and they provide two–thirds of all private sector jobs. So small firms are, in fact, the real ­giants of the European economy. Micro–business dominate employment in countries such as Italy 47 % and Poland 41 %, whilst the share of large enterprises in total employment in the United Kingdom is just 46 %.During the recent period of time there have been many researchers from the FBE MUAF in Brno, who focused on the analysis of the small and medium-sized enterprise, e.g. Nerudová (2006; Nerudová and Bohušová (2006; Kubíčková and Presová (2006; Zrůst and Pyšný (2008; Živělová and Zichová (2002.This paper is the part of the Research proposal MSM 6215648904 being solved at the FBE MUAF in Brno.

Claudinê Jordão de Carvalho

2015-08-01

Full Text Available This article investigates the determinant factors of supply and demand for trade credit by micro, small and medium-sized enterprises (MSMEs, using data collected in a survey of managers from 481 firms in 32 cities in the states of São Paulo and Minas Gerais (Brazil between 2008 and 2010. The multivariate relationship model proposed here is grounded in trade credit, agency and transaction costs theories. This study is based on a technique known as path analysis that uses a system of simple regressions estimated by simultaneous equations. The main results show the following: (i trade credit and short-term bank loans are supplementary (and not substitute sources of funds for MSMEs, which demonstrates that trade credit can be used by financial institutions as an indicator of the creditworthiness of the company; (ii the proportion of credit sales, the days sales outstanding measure and sales growth are positively related to the amount of trade credit demanded, which suggests that trade credit is transferred along the supply chain; and (iii the supply of trade credit is positively related to the importance that management ascribes to both internal capital and bank credit, which illustrates the strategic use of the supply of trade credit to increase sales. These results have important implications for companies' managers, financial institutions and the government agencies responsible for formulating policies that support and promote the development of small and medium-sized enterprises.

2015-09-15

The aim of this study was to evaluate the suitability of the ultrasonographic fetometry method, involving inner chorionic cavity diameter (ICC) and biparietal diameter (BP) measurements, to predict the parturition date in giant breed dogs. Overall, 30 ICC and 24 BP measurements were taken on 24 giant breed bitches. The measured values were substituted into Luvoni and Grioni (2000) formulas for medium-sized bitches because formulas with ICC and BP to dogs with a body mass greater than 40 kg have not been defined. The accuracy of the parturition date predictions proved the method to be highly useful in the observed group of dogs. Prediction accuracy in the giants ranged between 54.16% (± 1 day, using BP) and 90% (± 2 days, using ICC), depending on the parameter measured and precision levels used. Numerically, the results obtained using ICC were better; however, no statistically significant differences between ICC and BP accuracy were found when comparing the effectiveness of the parturition date predictions. Regression lines based on the own fetometric measurements were highly convergent with the lines defined by Luvoni and Grioni (2000) formulas for medium-sized bitches. This outcome suggests a similar gestational development of fetuses in giant dogs and the possible use of Luvoni and Grioni (2000) formulas for medium-sized dogs with breeds weighing greater than 40 kg.

Small- and medium-sized enterprises (SMEs) generate nearly 80% of the jobs in China, but the dangerous work environment often found in these enterprises poses a major concern for public health. Psychosocial pressure and mental health problems among the workers are also common in SMEs. However, mental health of workers in SMEs is largely neglected in occupational health research and practice in China. The purpose of this study is to assess mental health of the workers and to explore the associations between physical and psychosocial work environment and workers' mental health in SMEs in South China. Data were collected in 2012 through a cross-sectional survey among 1200 workers working in small- and medium-sized enterprises (SMEs) in Guangdong, China. Mental health was measured by psychological well-being in the current study. Job Demand-Control-Support (JDCS) model was used as a theoretical framework to examine the psychosocial factors associated with workers' psychological well-being. Data were analyzed using SPSS 20.0 and analysis was performed using bivariate analyses and multivariate logistic regression. About three in ten workers (35.3%) in the sample had poor psychological well-being. Those who were men, younger in age, or migrant workers had worse psychological outcome in bivariate analyses. After controlling for individual variables (gender, age, marital status, and household registration), we found that longer weekly work hours (OR = 1.30, 95% CI: 1.13 ~ 1.50), more exposure to hazardous work environment (OR = 1.26, 95% CI: 1.10 ~ 1.44), higher job demands (OR = 1.29, 95% CI: 1.12 ~ 1.49), and lower job autonomy (OR = 0.70, 95% CI: 0.60 ~ 0.81) were significant associated with worse psychological well-being. The results were consistent with predictions of the JDCS model. The results indicate that the JDCS model is a useful framework in predicting psychological well-being among Chinese workers in SMEs. Future mental health promotion should focus on young

Ruch, C; Stadler, H

2009-01-01

The present paper deals with the implementation of online data transferred via LEO satellite communication in a flood forecasting system. Although the project is ongoing, it is already recognised that the information chain: "measurement-transmission-forecast-alert" can be shortened, i.e., the flood danger can be more rapidly communicated to the population at risk. This gain is particularly valuable for medium size catchments where the concentration time (basin time of response to rainfall) is short.

To examine the effect of public reporting (PR) and financial incentives tied to quality performance on the use of care management practices (CMPs) among small- and medium-sized physician groups. Survey data from The National Study of Small and Medium-sized Physician Practices were used. Primary data collection was also conducted to assess community-level PR activities. The final sample included 643 practices engaged in quality reporting; about half of these practices were subject to PR. We used a treatment effects model. The instrumental variables were the community-level variables that capture the level of PR activity in each community in which the practices operate. (1) PR is associated with increased use of CMPs, but the estimate is not statistically significant; (2) financial incentives are associated with greater use of CMPs; (3) practices' awareness/sensitivity to quality reports is positively related to their use of CMPs; and (4) combined PR and financial incentives jointly affect CMP use to a greater degree than either of these factors alone. Small- to medium-sized practices appear to respond to PR and financial incentives by greater use of CMPs. Future research needs to investigate the appropriate mix and type of incentive arrangements and quality reporting. © Health Research and Educational Trust.

A large scale design space exploration can provide valuable insight into vehicle design tradeoffs being considered for the U.S. Army"s FMTV (Family of Medium Tactical Vehicles). Through a grant from TACOM (Tank-automotive and Armaments Command), researchers have generated detailed road, surface, and grade conditions representative of the performance criteria of this medium-sized truck and constructed a virtual powertrain simulator for both conventional and hybrid variants. The simulator incorporates the latest technology among vehicle design options, including scalable ultracapacitor and NiMH battery packs as well as a variety of generator and traction motor configurations. An energy management control strategy has also been developed to provide efficiency and performance. A design space exploration for the family of vehicles involves running a large number of simulations with systematically varied vehicle design parameters, where each variant is paced through several different mission profiles and multiple attributes of performance are measured. The resulting designs are filtered to remove dominated designs, exposing the multi-criterial surface of optimality (Pareto optimal designs), and revealing the design tradeoffs as they impact vehicle performance and economy. The results are not yet definitive because ride and drivability measures were not included, and work is not finished on fine-tuning the modeled dynamics of some powertrain components. However, the work so far completed demonstrates the effectiveness of the approach to design space exploration, and the results to date suggest the powertrain configuration best suited to the FMTV mission.

Correlates of Tax Compliance of Small and Medium Size Businesses in Cameroon

Directory of Open Access Journals (Sweden)

Oludele Akinloye Akinboade

2015-12-01

Full Text Available Taxation provides a predictable and stable flow of revenue to finance development objectives. This is important in a country like Cameroon that has serious challenges with meeting its development objectives. Small and medium enterprises (SMEs are significant for economic growth in the country, contributing as much as about 22 percent of the gross domestic product. SMEs generate taxable incomes. They also collect employment and value added taxes on behalf of the government. Taxation, however, imposes high cost to small businesses. SMEs are less tax compliant in comparison to large businesses. SMEs are considered the ‘hard to tax group from the informal sector.’ As such, the literature suggests that only a fraction of their taxable incomes is reported to tax authorities. Against this background, factors that correlate with tax compliance of 575 small and medium size companies in Cameroon are discussed from a survey of companies in the manufacturing and wholesale sectors. High registration cost and time-consuming processes promote tax non-compliance. The perception that tax system is corrupt discourages registration and filing compliance. When there are too many compliance hurdles, the probability of filing compliance is reduced. However, a fair and static system encourages filing and registration compliance. A clear and consistent tax system promotes filing compliance. Authorities that understand their responsibilities and are willing to respond to enquiries during the registration process promote tax compliance in general.

Specifics of Management in Small and Medium-Size Enterprises in Serbia

Directory of Open Access Journals (Sweden)

Marija Lazarević-Moravčević

2014-12-01

Full Text Available Under modern conditions for performing business, an enterprise regardless of its size or business activity must be systematically directed and run. Small and medium-size enterprises have certain characteristics that make them considerably different compared to large systems, therefore it is not realistic to expect that the management process in such organizations would develop in the same way as in the large systems. The fact is that the small business often does not involve a small investment, and the management of small enterprises is constantly faced with the problem of "poverty of resources" that leads to the conclusion that the success of SMEs is predominantly determined by the managerial skills of managers/owners. Assuming that the owners/managers of SMEs adequately perceive the capabilities of their enterprise, make the right decisions, finding effective solutions in terms of organization and apply modern approaches to control and the success of the company definitely will follow. In this paper theoretical and empirical research has been carried out with the aim to identify the basic characteristics of successful management of SMEs in Serbia. The research results indicate that the managerial capacity of managers/owners of SMEs is the main strength of the company, and one of the key sources of growth and development. When the influence of external factors is very unfavorable for business development, the management as an internal resource of organization is increasingly gaining importance in creating business success and competitive advantage.

Modelling detrital coral grain-size and age: Insights from sediment abrasion process of Yongle Atoll of South China Sea

Reef islands situated on the rims of atolls are composed almost exclusively of bioclastic materials locally supplied from adjacent coral reefs. Major skeletal component of these islands include coral, coralline algae, mollusks and foraminifera, produced in adjacent reefs. As the island builder, the bioclastic material is the sedimentary products, which also is the point of penetration to decipher the process. The bioclast of coral islands decrease in size with the transportation process. The grain-size provides a proxy record for the abrasion history of the unconsolidated sediment. The 230Th age of coral record the abrasion time. We hereby present a model to calculate the abrasion rate based on the data of 230Th age and grain-size of Yongle Atoll of Xisha Island, South China Sea. The grain size pattern in Yongle Atoll environment have confirm that the coral article diminution behave exponentially. The sediment composition of Yongle Atoll is identified, coral is dominant sediment constituent and the Th230 age is shown to exert an age distribution characteristics of coral detritus. We illustrate this approach by calculate the coral debris age of Xude Atoll, which located near the Yongle Atoll and then by comparing actual measured age and calculated age and to explore the dependence of the model. Observed 230 Th ages are well matched by predicted ages for medium age sediment. A poorer match for young and old sediment may result from some combination of large analytical uncertainties in the detrital ages and inhomogeneous erosion rates within the atoll. Such mismatches emphasize the need for more accurate kinematic models and for sampling strategies that are adapted to atoll-specific geologic and geomorphic conditions. Results presented constitute important new insights into regional sediment abrasion processed and on the evolution of coral atoll islands.

Innovative small and medium sized reactors (SMRs) have several features that are expected to affect their future development and deployment in India. These include the: - Potential for simpler designs and reduced demands for human intervention, resulting in fewer potentially unsafe actions; - Potential for construction close to population centres, due to enhanced safety; - Potential of using the capability and capacity of local industries to enable their participation in the design and construction of such reactors, and high adaptability to the standardization and modular construction approach; - Potential to achieve low upfront capital costs. Future SMR concepts, employing increased use of passive safety features and capable of producing both electricity and high temperature process heat, may find application in specific regions of the country to supply both electricity and process heat, through distributed deployment. The following sections describe future SMR design concepts meeting the above mentioned objectives, and highlight their projected economic competitiveness.

Full Text Available Creativity is a process of development and expression of new ideas interwoven in the company mission and vision to lead not only to financial success but also to real loyalty and involvement of the employees with the company problems and achievements. The main objective of this paper is through the research among contemporary managers and entrepreneurs, representatives of small and medium-sized business in the region of Blagoevgrad to prove that creativity skills are deployed in each person, to identify the specific characteristics of the creative thinking of the manager and the tools that stimulate them to increase competitiveness in the context of the sustainable development of the small and medium business in international and domestic tourism market. The main result to be achieved is evidence that when there is adequate (positive self-evaluation, intrinsic motivation or chiefly necessity of creativity manifestation, emotivity in the sense of creative enthusiasm, personal professional effectiveness and appropriate situational factors, the modern manager is able to model conditions for the manifestation of creativity (creative self-expression, both in themselves and in their subordinates. This in turn leads to increased competitiveness and intensive implementation of innovations in the company management and operation. The main research methods used in the study are literature review on the subject, survey, analysis of processes, intuitive and systematic approach, systematic observation, data classification and interpretation.

2018-04-01

A new medium-sized washer gun is developed for a plasma start-up in a fully axisymmetric mirror. The gun is positioned at the east end of the Keda Mirror with AXisymmetricity facility and operated in the pulsed mode with an arc discharging time of 1.2 ms and a typical arc current of 8.5 kA with 1.5 kV discharge voltage. To optimize the operation, a systematic scan of the neutral pressure, the arc voltage, the bias voltage on a mesh grid 6 cm in front of the gun and an end electrode located on the west end of mirror, and the mirror ratio was performed. The streaming plasma was measured with triple probes in the three mirror cells and a diamagnetic loop in the central cell. Floating potential measurements suggest that the plasma could be divided into streaming and mirror-confined plasmas. The floating potential for the streaming plasma is negative, with an electric field pointing inwards. The mirror-confined plasma has a typical lifetime of 0.5 ms.

Critical gaps in our understanding of the distributions, interactions, life histories and preferred habitats of large and medium-size pelagic fishes severely constrain the implementation of ecosystem-based, spatially structured fisheries management approaches. In particular, spawning distributions and the environmental characteristics associated with the early life stages are poorly documented. In this study, we consider the diversity, assemblages, and associated habitat of the larvae of large and medium-sized pelagic species collected during 2 years of monthly surveys across the Straits of Florida. In total, 36 taxa and 14,295 individuals were collected, with the highest diversity occurring during the summer and in the western, frontal region of the Florida Current. Only a few species (e.g. Thunnus obesus, T. alalunga, Tetrapturus pfluegeri) considered for this study were absent. Small scombrids (e.g. T. atlanticus, Katsuwonus pelamis, Auxis spp.) and gempylids dominated the catch and were orders of magnitude more abundant than many of the rare species (e.g. Thunnus thynnus,Kajikia albida). Both constrained (CCA) and unconstrained (NMDS) multivariate analyses revealed a number of species groupings including: (1) a summer Florida edge assemblage (e.g. Auxis spp., Euthynnus alleterattus, Istiophorus platypterus); (2) a summer offshore assemblage (e.g. Makaira nigricans, T. atlanticus, Ruvettus pretiosus, Lampris guttatus); (3) an ubiquitous assemblage (e.g. K. pelamis, Coryphaena hippurus, Xiphias gladius); and (4) a spring/winter assemblage that was widely dispersed in space (e.g. trachipterids). The primary environmental factors associated with these assemblages were sea-surface temperature (highest in summer-early fall), day length (highest in early summer), thermocline depth (shallowest on the Florida side) and fluorescence (highest on the Florida side). Overall, the results of this study provide insights into how a remarkable diversity of pelagic species

Full Text Available Small and medium-sized enterprises play an important role in the economy, creates, because a significant part of GDP, provides employment to many millions of people. One of the main barriers to the development of these enterprises, not only in Poland but also in EU countries, is the scarcity of equity and the difficulty in obtaining external sources of financing. It is not just about lack of funds to finance current operations, but also, and perhaps above all, lack of investment in fixed assets. This paper aims to present available sources of financing of fixed assets for enterprises from the SME sector and the assessment of their use by these companies.

Full Text Available Dense medium cyclone (DMC is widely used in mineral industry to separate solids by density. It is simple in design but the flow pattern within it is complex due to the size and density distributions of the feed and process medium solids, and the turbulent vortex formed. Recently, the so-called combined computational fluid dynamics (CFD and discrete element method (DEM (CFD-DEM was extended from two-phase flow to model the flow in DMCs at the University of New South Wales (UNSW. In the CFD-DEM model, the flow of coal particles is modelled by DEM and that of medium flow by CFD, allowing consideration of medium-coal mutual interaction and particle-particle collisions. In the DEM model, Newton's laws of motion are applied to individual particles, and in the CFD model the local-averaged Navier-Stokes equations combined with the volume of fluid (VOF and mixture multiphase flow models are solved. The application to the DMC studies requires intensive computational effort. Therefore, various simplified versions have been proposed, corresponding to the approaches such as Lagrangian particle tracking (LPT method where dilute phase flow is assumed so that the interaction between particles can be ignored, one-way coupling where the effect of particle flow on fluid flow is ignored, and the use of the concept of parcel particles whose properties are empirically determined. In this paper, the previous works on the modelling of DMCs at UNSW are summarized and the features and applicability of the models used are discussed.

The traffic situation in Chinese urban areas is continuing to deteriorate. To make a better planning and designing of the public transport system, it is necessary to make profound research on the structure of urban public transport networks (PTNs). We investigate 97 large- and medium-sized cities’ PTNs in China, construct three types of network models — bus stop network, bus transit network and bus line network, then analyze the structural characteristics of them. It is revealed that bus stop network is small-world and scale-free, bus transit network and bus line network are both small-world. Betweenness centrality of each city’s PTN shows similar distribution pattern, although these networks’ size is various. When classifying cities according to the characteristics of PTNs or economic development level, the results are similar. It means that the development of cities’ economy and transport network has a strong correlation, PTN expands in a certain model with the development of economy.

A bench to measure the magnetic field of small to-medium-sized magnets with high precision was built. It uses a small-sized head with three orthogonal Hall probes, supported on a long pole at continuous movement during measurement. The head is calibrated in three dimensions by rotation over the full solid angle in a special device. From 0 to 2.5 T, the precision is ±0.2 mT in all components. The spatial range is 1 × 1 × 2 m with precision of ±0.02 mm. The bench and its controls are lightweight and easy to transport. The head can penetrate through small apertures and measure as close as 0.5 mm from the surface of a magnet. The bench can scan complicated grids in Cartesian or cylindrical coordinates, steered by a simple text file on an accompanying PC. The raw data is online converted to magnetic units and stored in a text file.

Full Text Available The paper provides a comparative analysis of the results of innovation activities in enterprises of different size from EU member and candidate states during the period 2008-2010. Particularly, the paper considers position of Serbia compared to the EU average and average of some neighboring countries (Hungary, Slovenia, Croatia, Romania and Bulgaria. The results confirmed the existence of a high correlation between size of enterprise and its innovation activities. The percentage of innovation activities in large enterprises is higher than in small enterprises. Serbia is lagging behind the EU average, regarding innovativeness level in all types of enterprises (classified by size. However, when Serbia is compared to neighboring countries, the situation is much different. Small enterprises from Serbia are more innovative than small enterprises from neighboring countries. The situation is similar in medium-sized enterprises. Large enterprises from Serbia are more innovative than enterprises from Bulgaria, Hungary and Romania, and less innovative than large enterprises from Slovenia and Croatia.

Theory of flotation of small and medium-size particles

Derjaguin, B. V.; Dukhin, S. S.

1993-08-01

The paper describes a theory of flotation of small and medium-size particles less than 50μ in radius) when their precipitation on a bubble surface depends more on surface forces than on inertia forces, and deformation of the bubble due to collisions with the particles may be neglected. The approach of the mineral particle to the bubble surface is regarded as taking place in three stages corresponding to movement of the particles through zones 1, 2 and 3. Zone 3 is a liquid wetting layer of such thickness that a positive or negative disjoining pressure arises in this intervening layer between the particle and the bubble. By zone 2 is meant the diffusional boundary layer of the bubble. In zone 1, which comprises the entire liquid outside zone 2, there are no surface forces. Precipitation of the particles is calculated by considering the forces acting in zones 1, 2 and 3. The particles move through zone 1 under the action of gravity and inertia. Analysis of the movement of the particles under the action of these forces gives the critical particle size, below which contact with the bubble surface is impossible, if the surface forces acting in zones 2 and 3 be neglected. The forces acting in zone 2 are ‘diffusio-phoretic’ forces due to the concentration gradient in the diffusional boundary layer. The concentration and electric field intensity distribution in zone 2 is calculated, taking into account ion diffusion to the deformed bubble surface. An examination is made of the ‘equilibrium’ surface forces acting in zone 3 independent of whether the bubble is at rest or in motion. These forces, which determine the behaviour of the thin wetting intervening layer between the bubble and the mineral particle and the height of the force barrier against its rupture, may be represented as results of the disjoining pressure forces acting on various parts of the film. The main components of the disjoining pressure are van der Waals forces, forces of an iono

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.

2012-02-01

Full Text Available Information Technology (IT adoption is an important field of study in a number of areas, which include small and medium-sized enterprises (SMEs. Due to the numerous advantages of IT, SMEs are trying to adopt IT applications to support their businesses. IT adoption by SMEs differs from larger organizations because of their specific characteristics, such as resources constraints. Therefore, this research aims to provide a better and clearer understanding of IT adoption within SMEs by reviewing and analyzing current IT literature. In this research, the review of literature includes theories, perspectives, empirical research and case studies related to IT adoption, in particular within SMEs from various databases such as Business Premier, Science Direct, JStor, Emerald Insight and Springer Link. The proposed model of effective IT adoption is believed to provide managers, vendors, consultants and governments with a practical synopsis of the IT adoption process in SMEs, which will in turn assist them to be successful with IT institutionalization within these businesses.

Scrutinizing critical thermodynamic and kinetic factors for glass formation and the glass stability of materials would benefit the screening of the glass formers for the industry of glassy materials. The present work aims at elucidating the factors that contribute to the glass formation by investigating medium-sized molecules of pharmaceuticals. Glass transition related thermodynamics and kinetics are performed on the pharmaceuticals using calorimetric, dielectric, and viscosity measurements. The characteristic thermodynamic and kinetic parameters of glass transition are found to reproduce the relations established for small-molecule glass formers. The systematic comparison of the thermodynamic and kinetic contributions to glass formation reveals that the melting-point viscosity is the crucial quantity for the glass formation. Of more interest is the finding of a rough correlation between the melting-point viscosity and the entropy of fusion normalized by the number of beads of the pharmaceuticals, suggesting the thermodynamics can partly manifest its contribution to glass formation via kinetics.

Full Text Available Understanding the transmission dynamics of infectious diseases is important to allow for improvements of control measures. To investigate the spatiotemporal pattern of an epidemic dengue occurred at a medium-sized city in the Northeast Region of Brazil in 2009, we conducted an ecological study of the notified dengue cases georeferenced according to epidemiological week (EW and home address. Kernel density estimation and space-time interaction were analysed using the Knox method. The evolution of the epidemic was analysed using an animated projection technique. The dengue incidence was 6.918.7/100,000 inhabitants; the peak of the epidemic occurred from 8 February-1 March, EWs 6-9 (828.7/100,000 inhabitants. There were cases throughout the city and was identified space-time interaction. Three epicenters were responsible for spreading the disease in an expansion and relocation diffusion pattern. If the health services could detect in real time the epicenters and apply nimbly control measures, may possibly reduce the magnitude of dengue epidemics.

ElBaradei, M.

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

The social effectiveness of small and medium-sized entities standard from the view point of Game Theory

Alexandre Gonzales

2013-05-01

Full Text Available Accounting has been undergoing significant changes, and among these changes is the creation of a standard for the accounting of small and medium enterprises, in line with international accounting standards for companies of this size. This rule arose from the development of a pronouncement by the Accounting Pronouncements Committee – CPC, which subsequently was approved by the Federal Accounting Council - CFC through specific resolutions. The present study aimed to analyze trends of accounting professionals and business managers concerning the adoption of Technical Pronouncement emitted by Accounting Pronouncements Committee for Small and Medium Enterprises. Considering the level of complexity of the operations performed by companies of this size, the lack of oversight by specific entities and the question of enforcement of these pronouncements, it was used the game theory to determine possible strategies adopted by the accountants and business managers regarding to the effective adoption of pronouncement for SMEs. The study was characterized as a descriptive research, using bibliographical and field research. With the use of surveys sought to identify the perceptions of accounting professionals regarding the adoption of the pronouncement. It was found that this statement constitutes a valid legal standard, endowed with legal effectiveness and technical efficiency, but lacking social effectiveness, due to the low level of efforts for its adoption, both by accounting professionals and by firms.

Small and Medium Sized Reactors: Driving Forces and Technology Development

International Nuclear Information System (INIS)

Gowin, P.J.; Kupitz, J.

2002-01-01

There will be growing demands for energy in the coming decades. One aspect of particular importance is that prospects for nuclear energy will to a considerable extent be influenced by developing countries. Since population growth will occur primarily in developing countries nuclear energy cannot play a significant global role without being a viable option in these countries. Since new power plants to be built will have to be compatible with regional electricity grids, this may result in a greater focus on plants in the small and medium range, defined by the International Atomic Energy Agency (IAEA) to produce up to 700 Megawatt of electrical power. This paper first examines the driving forces that could influence the development of nuclear energy in general and of Small and Medium Sized Reactors (SMRs) in particular in the next decades and identifies key factors in that process. Concerns over climate change may to a certain extent influence the discussion on future energy options. Other factors of equal importance for the future of nuclear are a continued emphasis on maintaining high safety standards, the implementation of acceptable solutions for spent fuel and radioactive waste disposal and a globally accepted non-proliferation regime, factors that may in turn have an impact on public acceptance. Economic competitiveness of nuclear energy is an additional important factor, and without being commercially viable, no energy source can in the long run represent a major and stable component in a competitive energy sector. The introduction of SMRs in developing countries poses additional challenges, such as investment limitations. Technology development plays an important role in keeping the nuclear option open for countries wishing to use nuclear reactors to meet their energy needs, and advances in reactor design will be important to enable a significant nuclear component in developing countries. This paper considers the contribution that nuclear science and

Full Text Available Considering the fundamental role of small and medium enterprises in Romanian economy, this paper aims to quantify the level of their bankruptcy risk for 2009 and 2012 period, after debuting of financial crisis. The main reason of selecting this type of companies is that they represent the backbone of national economy. They have an indispensable role, because they offer jobs for great part of population and their contribution for GDP stimulation is considerable. In this paper it was applied two default risk models, namely the well known Altman’s Z-score model, based on five financial ratios and a bankruptcy predictor model developed by Teti et. al (2012 used firstly exclusively for Italian small and medium-sized enterprise for 2006-2009 period. The model proposed by Teti et. is based on the investigation of financially distressed and financially non-distressed Italian small and medium-sized enterprises during the financial crisis by using a discriminant analysis model. They conclude that there are four financial ratios, which characterized well the small and medium-sized enterprises bankruptcy risk. These variables are financial ratios, like: Debt/Total Assets, Return on Sales (ROS, EBIT/Interest Expenses and Working capital/EBIDTA. They consider that small and medium-sized enterprises require a particular approach in terms of bankruptcy risk analysis. In present study I try to compare the efficiency of traditional bankruptcy risk model with a small and medium-sized specific model. The necessary database for present analysis is ensured by simplified financial reports of 120 small and medium-sized enterprises registered in Bihor County. The selected enterprises are operating in manufacturing industry (21,67% and trading (78,33%. Present investigation has an important value in actual economic background, where the healthiness and sustainability of small and medium-sized enterprises is a great issue.

Cities in emerging countries are facing a fast growth and urbanization; however, the study of air pollutant emissions and its dynamics is scarce, making their populations vulnerable to potential effects of air pollution. This situation is critical in medium-sized urban areas built along the tropical Andean mountains. This work assesses the contribution of on-road vehicular and point-source industrial activities in the medium-sized Andean city of Manizales, Colombia. Annual fluxes of criteria pollutants, NMVOC, and greenhouse gases were estimated. Emissions were dominated by vehicular activity, with more than 90% of total estimated releases for the majority of air pollutants. On-road vehicular emissions for CO (43.4 Gg/yr) and NMVOC (9.6 Gg/yr) were mainly associated with the use of motorcycles (50% and 81% of total CO and NMVOC emissions respectively). Public transit buses were the main source of PM10 (47%) and NOx (48%). The per-capita emission index was significantly higher in Manizales than in other medium-sized cities, especially for NMVOC, CO, NOx and CO2. The unique mountainous terrain of Andean cities suggest that a methodology based on VSP model could give more realistic emission estimates, with additional model components that include slope and acceleration. Food and beverage facilities were the main contributors of point-source industrial emissions for PM10 (63%), SOx (55%) and NOx (45%), whereas scrap metal recycling had high emissions of CO (73%) and NMVOC (47%). Results provide the baseline for ongoing research in atmospheric modeling and urban air quality, in order to improve the understanding of air pollutant fluxes, transport and transformation in the atmosphere. In addition, this emission inventory could be used as a tool to identify areas of public health exposure and provide information for future decision makers.

Dejan ERIC

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.

Full Text Available The new EU-Accounting Directive of 26 June 2013 (DIRECTIVE 2013/34/EU has the intention to harmonize the accounting and financial reporting of enterprises in the European Union. “Think small first” is the central principle in the new EU-Accounting Directive and the new regulations have to be adopted in the laws of European member states by 20 July 2015. The International Financial Reporting Standard for Small and Medium-sized Entities (IFRS for SMEs was published in 2009 by the International Accounting Standards Board (IASB. The IASB intended to create simplified international financial reporting standards for the special needs of smaller and medium-sized enterprise. The IASB completed in May 2015 a comprehensive review of the IFRS for SMEs and made amendments to the Standard. The revised version of the IFRS for SMEs will be issued in the last quarter of 2015. The aim of the paper is to analyze the compatibility of the IFRS for SMEs and the new EU- Accounting Directive and the problems in connection with the harmonization of the European accounting legislation especially in Germany. Based on the results of the research most of the former incompatibilities could be removed, but the remaining complexity of the IFRS for SMEs and the lack of an option for the member states to adopt the IFRS for SMEs as an accounting and reporting standard besides or instead their local accounting principles will prevent the wide use of the IFRS for SMEs in Germany and in other member states of the European Union.

A two-dimensional radiophotoluminescent system for medium-sized field dosimetry has been developed using a silver-activated phosphate glass plate with a dimension of 120 mmx120 mmx1 mm and a readout unit comprising a UV excitation lamp and a CCD imager. A dose ranging from 0 to 400 cGy, provided by a 6 MV x-ray beam, was delivered to the glass plate oriented perpendicularly to the beam and positioned in a water phantom at a depth of 10 cm, where the center of the glass plate coincided with the linac isocenter. After the dose delivery, the glass plate was placed in the readout system. The CCD output intensity increased linearly with the applied dose. The angular dependence of response on the direction of radiation incidence was measured by rotating the glass plate in the water phantom, indicating that the output remained constant up to 75 deg. from perpendicular incident direction, followed by a steep reduction down to 85% at an angle of 90 deg. A lateral dose distribution resulting from a 60 mmx60 mm irradiation was compared between the glass plate and an x-ray film having had the same exposure, showing that the glass plate and the x-ray film led to identical dose distributions. The dose reproducibility for a glass plate and the sensitivity variation among different glass plates were also evaluated

Seed crop size variation in the dominant South American conifer Araucaria angustifolia

Science.gov (United States)

Souza, Alexandre F.; Uarte de Matos, Daniele; Forgiarini, Cristiane; Martinez, Jaime

2010-01-01

Temporal variation in seed crop size of the long-lived pioneer conifer Araucaria angustifolia was studied in subtropical South America. We evaluated the expectations that: 1) A. angustifolia presents highly variable seed production (mast seeding behavior); 2) A. angustifolia has endogenous cycles of reproduction of two or three years; 3) There is a tendency for a high seed production year to be followed by an unusually low production year; 4) populations show synchrony in seed production at a geographical scale; 5) seed crop size is influenced by distinct climatic factors occurring during "key" reproductive stages and 6) as an expression of plant productivity, seed crop size should depend on integrated resource availability during the reproductive cycle. We obtained data from two distinct sources: 1) seed harvesting records from a private forest (14 years), and 2) commercial data from 22 municipalities in the Rio Grande do Sul State. Expectations 1, 2, 3 and 5 were not met, while expectations 4 and 6 were supported by the data. A. angustifolia showed environmentally triggered, continuous, moderately fluctuating, and regionally synchronous reproduction. Seed set seems to track variations in resource abundance as well as respond continuously to improved opportunities for successful regeneration.

Tidal River Elbe - a sediment budget for the grain size fraction of medium sand

Winterscheid, Axel

2016-04-01

Human interventions have a historic and ongoing impact on estuarine sediment budgets across many estuaries worldwide. An early inference was the construction of embankments resulting in a constant loss of intertidal flats. Additionally, settlement activities and large scale land use changes in the upstream catchment areas had also an effect on sediment inflow rates. Today, the navigation channels in estuaries have been deepened for larger and more efficient vessels to reach a well-developed infrastructure of harbors and industrial areas often located far inland. In the past few years and just within the North-East Atlantic, the total annual amount of dredged sediments dumped at sea varied from 80 to 130 million tons (OSPAR Commission). In most estuaries across Europe the resulting human impact on the sediment fluxes and morphodynamics is significant. A good understanding of estuarine processes is essential for determining useful and meaningful measures to mitigate negative effects and to improve the current situation. Maintenance dredging and its environmental effects are therefore in the focus of public attention. Against this background, it is the aim of the presentation to identify and therefore to separate the particular effect that maintenance dredging has on sediment fluxes and budgets in the estuarine environment. Case study is the Tidal River Elbe in Germany, and here we set the focus on the grain size fraction of medium sand. In the past, river engineering measures forced the natural dynamics to form a concentrated stream flow along a fixed channel, except at a number of locations where side channels still exist. In addition to that, the main channel was deepened several times. The last deepening was in 1999/2000. The most significant deepening, however, took place from 1957 to 1962. Until then, an erosion-stable layer of marine clay (in German called "Klei") formed a flat bottom along most sections of the main channel. After removal of this layer of

Full Text Available Information Systems Security (ISS is a relevant fact for current organizations. This paper focuses on Small and Medium Sized Enterprises (SMEs. This article aims to constitute an empirical study on the applicability of the Action Research (AR method in information systems, more specifically by assessing the adoption of an ISS policy in six SMEs, and identifying the critical success factors in adopting an ISS policy. The research question we intend to answer is to what extent this research method is adequate to reach the proposed goal. The results of the study suggest that AR is a promising means for the evaluation of ISS policies adoption. It can both act as a research method that improves the understanding about the reasons why the policy has been abandoned, and as a change method, assisting practitioners to overcome barriers and suggesting measures to be implemented.

PurposeTo retrospectively investigate the safety and efficacy of hybrid proximal coiling of various medium-sized vessels (4 to 8 mm) using the Penumbra Occlusion Device (POD).Materials and MethodsFrom October 2014 to February 2016, 37 proximal embolizations were performed with PODs in 36 patients (mean age: 50.8, range: 10–86; 29 male, 7 female). Vessel occlusions were achieved under fluoroscopic guidance using a 2.7 French microcatheter. Among the 36 vessels targeted, 16 were splenic arteries, 11 renal arteries, 4 mesenteric arteries, 3 arteriovenous fistulae, 1 iliac artery, and 1 gonadal vein. Intermittent follow-up angiography was performed to assess the flow for final occlusion. Outcomes and complications were assessed by clinical and/or imaging follow-up.ResultsTo produce proximal occlusion of the intended vessels, the POD was used alone in 19 embolizations (51.4 %). In 12 procedures (32.4 %), POD was used as a coil constrainer to secure the coil construct. In 6 procedures (16.2 %), additional embolic devices were used to achieve vessel occlusion after initial POD deployment. After a mean follow-up of 3.2 months, no POD migration was observed but two complications occurred (5.4 %): one post embolic syndrome and one extensive infarction with splenic abscess.ConclusionThe POD system allows safe and effective proximal embolization of medium-sized vessels in a variety of clinical settings.

Design and deployment strategies for small and medium sized reactors (SMRs) to overcome loss of economies of scale and incorporate increased proliferation resistance

International Nuclear Information System (INIS)

Kuznetsov, V.

2007-01-01

The designers of innovative small and medium sized reactors pursue new design and deployment strategies making use of certain advantages provided by smaller reactor size and capacity to achieve reduced design complexity and simplified operation and maintenance requirements, and to provide for incremental capacity increase through multi-module plant clustering. Competitiveness of SMRs (Small and Medium size Reactor) depends on the incorporated strategies to overcome loss of economies of scale but equally it depends on finding appropriate market niches for such reactors. For many less developed countries, these are the features of enhanced proliferation resistance and increased robustness of barriers for sabotage protection that may ensure the progress of nuclear power. For such countries, small reactors without on-site refuelling, designed for infrequent replacement of well-contained fuel cassette(s) in a manner that impedes clandestine diversion of nuclear fuel material, may provide a solution. Based on the outputs of recent IAEA activities for innovative SMRs, the paper provides a summary of the state-of-the-art in approaches to improve SMR competitiveness and incorporate enhanced proliferation resistance and energy security.

2018-04-01

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

The Small and medium integral reactor is developed to be utilized for non-electric areas such as district heating and steam production for desalination and other industrial purposes, and then these applications may typically imply a closeness between the reactor and the user. It requires the reactor to be designed with the adoption of special functional and inherent safety features to ensure and promote a high level of safety and reliability, in comparison with the existing nuclear power plants. The objective of the present study is to establish the bases for the development of regulatory requirements and technical guides to address the special safety characteristics of the small and medium integral reactor. In addition, the study aims to identify and to propose resolutions to the possible safety concerns in the design of the small and medium integral reactor. 34 refs., 20 tabs. (author)

Atomic size effects on local coordination and medium range order in molten trivalent metal chlorides

International Nuclear Information System (INIS)

Tatlipinar, H.; Akdeniz, Z.; Pastore, G.

1992-08-01

Structural correlations in molten trivalent metal chlorides are evaluated as functions of the metal ion size R M across the range from LaCl 3 (R M approx. 1.4 A) to AlCl 3 (R M approx. 0.8 A), using a charged soft-sphere model and the hypernetted chain approximation. Main attention is given to trends in the local liquid structure (partial radial distribution functions, coordination numbers and bond lengths) and in the intermediate range order (first sharp diffraction peak in the number-number and partial structure factors). The trend towards fourfold local coordination of the metal ions, the stabilization of their first-neighbour chlorine cage and the growth of medium range order are found to proceed in parallel as the size of the metal ion is allowed to decrease at constant number density and temperature. A tendency to molecular-type local structure and liquid-vapour phase separation is found within the hypernetted chain scheme at small metal ion sizes corresponding to AlCl 3 and is emphasized by decreasing the number density of the fluid. The predicted molecular units are rather strongly distorted Al 2 Cl 6 dimers, in agreement with observation. The calculated structural trends for other trichlorides are compared with diffraction and transport data. (author). 17 refs, 8 figs, 1 tab

1998-01-01

The small and medium size reactors (SMR) and interface facilities such as desalination plant are expected to be located near the population area because of restrictions in transporting the plant products such as fresh water to long distance area. To protect the public around the plant facility from the possible release of radioactive materials, the design development of the SMR is focusing on an enhancement of the safety and reliability as well as the economics. In this study, the major safety concepts of the SMR designs significantly different from the current PWR designs are investigated and the safety concerns applicable to the integrated SMR design of Korea (called SMART), were identified. Those safety issues include the use of proven technology, application of strengthening defense in depth, event categorization and selection, simplification of emergency planning, determination of accident source terms and so on. The efforts to resolve the safety concerns in the design stage will provide an improvement of the safety of the SMART design

Improved Cost Management at Small and Medium Sized Road Transport Companies: Case Hungary

Directory of Open Access Journals (Sweden)

Zoltan Bokor

2015-10-01

Full Text Available Small and medium sized road freight transport companies located in Hungary are facing strong competition on the logistics market. An advanced cost management system supporting decisions on capacity allocations or pricing may be a competitive advantage for them and indirectly for the whole economy as well. Still, they generally apply simple, traditional cost calculation regimes, potentially sufficient in case of a homogeneous service portfolio. Nevertheless, road haulage companies with heterogeneous service structures may witness information distortions when using traditional costing methods. So it might be recommended for them to introduce better costing principles. To support an improved transport costing, a multi-level full cost allocation model has been set up and tested in this paper. The research results have pointed out that such a methodological development accompanied by the extension of the data collection mechanism can contribute to making the cost management systems of road freight transport companies more effective.

2013-10-01

Full Text Available Source separation is a common method for dealing with the increasing problem of Municipal Solid Waste (MSW in society. The citizens are then responsible for separating waste fractions produced in their home. If the consumers fail to sort the waste according to the source separation scheme, it will lead to an ineffective system. The purpose of this paper is to analyze the environmental, economic and social aspects of incorrect waste sorting in a medium sized Swedish city that has established a source separation system. In order to determine the extent to which citizens correctly sort their waste, food waste (black bags and combustible fraction (white bags, were collected randomly from a residential area and categorized in different waste fractions. The results show that approximately 68 wt% of the waste in the white and 29 wt% in the black bags were not sorted correctly. This incorrect sorting accrues over 13 million SEK per year cost for this community. In order to improve the inhabitants’ participation in the waste management system, it is necessary to change different factors such as convenience and easy access to the recycling stations in the local MSW management systems as well as to review current regulation and policy.

The purpose of this study was to determine whether the methods used in compost operations of small and medium-sized poultry farms resulted in the production of an amendment free of foodborne pathogens. Nine compost heaps on five South Carolina poultry farms were surveyed at different stages of the composting process. Compost samples were analysed for coliforms and enriched for Escherichia coli O157:H7, Salmonella spp. and Listeria monocytogenes. The waste materials and composting practices differed among the surveyed farms. On two farms, new materials were added to heaps that had previously completed the active composting phase. Five compost heaps did not reach an internal temperature of 55 degrees C, and c. 62% of all internal samples in the first composting phase contained moisture contents poultry wastes. This research provides information regarding the effectiveness of the composting practices and microbiological quality of poultry compost produced by small- and medium-sized farms. Ensuring the safety of compost that may be applied to soils should be an integral part of preharvest food safety programme.

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.

2015-10-01

Full Text Available In spite of the key role played by the Small and Medium enterprises in economic development, there has been little effort to look at what needs to be done to improve survival and growth of SMEs. There is still a general lack of in-depth understanding from policy makers and other relevant stakeholders of how SMEs can be used as a strategic tool for economic growth and job creation in South Africa. These misperceptions and misunderstand leads to continuous failure to SMEs survival and growth. This study seeks to address this research gap. The study investigates the public views on what needs to be done to grow South African economy through the development of SMEs. Quantitative research approach was used to collect and analyse data for the study. Primary data was collected from four (4 provinces of South Africa. 230 people participated in the study. Questionnaires were emailed to each respondent and follow-ups were made via telephone. It was found that many SMEs fail within five years of their existence due to the various reasons. The most critical of these were related to lack of access to finance, lack of management experience as well as human capital. Study further revealed that most the SMEs owners/managers do not have business management related skills but rather they are just ordinary entrepreneurs

It is determined that entrepreneurship in agrarian sector is a driving force behind the development of agriculture, as these activities contributes to the production of quality agricultural products that satisfies the needs of society, food security, independence and improves the living standards of rural population. Potential customers of small parties of harvest in Ukrainian grain market are analyzed. The ways of mutually beneficial cooperation between Ukrainian farmers and entrepreneurs are proved. The study of foreign experience has proven that strengthening the competitiveness of Ukrainian agricultural products in the context of globalization is possible on the basis of mutually beneficial cooperation of Ukrainian farmers and entrepreneurs, where recent purchase of output at market prices for the purpose of resale or creation of agricultural cooperatives, such form of economy in agrarian relations that combines a balanced economic, social and environmental components. In particular in paper is shown that sustainable economic management provide only forms of economy that take into account the socioeconomic and geophysical specifics of agriculture, particularities of agricultural labor and methods of management. The most common among these forms are farmers.

Feasibility of a medium-size central cogenerated energy facility, energy management memorandum

Science.gov (United States)

Porter, R. W.

1982-09-01

The thermal-economic feasibility was studied of a medium-size central cogenerated energy facility designed to serve five varied industries. Generation options included one dual-fuel diesel and one gas turbine, both with waste heat boilers, and five fired boilers. Fuels included natural gas, and for the fired-boiler cases, also low-sulphur coal and municipal refuse. The fired-boiler cogeneration systems employed back-pressure steam turbines. For coal and refuse, the option of steam only without cogeneration was also assessed. The refuse-fired cases utilized modular incinerators. The options provided for a wide range of steam and electrical capacities. Deficient steam was assumed generated independently in existing equipment. Excess electrical power over that which could be displaced was assumed sold to Commonwealth Edison Company under PURPA (Public Utility Regulator Policies Act). The facility was assumed operated by a mutually owned corporation formed by the cogenerated power users. The economic analysis was predicted on currently applicable energy-investment tax credits and accelerated depreciation for a January 1985 startup date. Based on 100% equity financing, the results indicated that the best alternative was the modular-incinerator cogeneration system.

  Urban water systems (UWSs) are challenged by the sustainability perspective. Certain limitations of the sustainability of centralized UWSs and decentralized household level wastewater treatments can be overcome by managing UWSs at an intermediate scale, referred to as small to medium sized UWSs (SMUWSs). SMUWSs are different from large UWSs, mainly in terms of smaller infrastructure, data limitation, smaller service area, and institutional limitations. Moreover, sustainability assessment systems to evaluate the sustainability of an entire UWS are very limited and confined only to large UWSs. This research addressed the gap and has developed a set of 38 applied sustainability performance indicators (SPIs) by using fuzzy-Elimination and Choice Translating Reality (ELECTRE) I outranking method to assess the sustainability of SMUWSs. The developed set of SPIs can be applied to existing and new SMUWSs and also provides a flexibility to include additional SPIs in the future based on the same selection criteria.

2017-06-01

Full Text Available The South-Central region of Mexico has experienced a sizeable introduction of purebred horses for recreational aims. A study was designed to assess effective population sizes and genetic diversity and to verify the genetic integrity of four horse breeds. Using a 12-microsatellite panel, Quarter Horse, Azteca, Thoroughbred and Creole (CRL horses were sampled and analysed for diversity and genetic structure. Genetic diversity parameters showed high numbers of heterozygous horses but small effective population sizes in all breeds. Population structure results suggested some degree of admixture of CRL with the other reference breeds. The highly informative microsatellite panel allowed the verification of diversity in introduced horse populations and the confirmation of small effective population sizes, which suggests a risk for future breed integrity.

RISK MANAGEMENT IN SMALL AND MEDIUM – SIZED ENTERPRISES: A GENDER-SENSITIVE APPROACH

2015-12-01

Full Text Available Risk is inherent in all business functions and in every kind of activity. Small and medium-sized enterprises (SMEs are particularly vulnerable to continuously daily internal and external undesirable events that adversely affect business performance. To deal with many risk determinants effectively, SMEs need a systemic method of approach to risk management. One of the factors of company risk management approach is gender of the owners or top executives. Especially from a managerial perspective, the link between risk-taking and gender has been examined through a wide range of approaches, such as entrepreneurial orientation and leadership related literatures. Some researchers point that male SME owners appear to show a greater risk appetite than female SME owners. The leading question in the undertaken research was to determine whether the gender of the firm's owners or top executives are reflected in the approach to risk management. The focal point of the research is identification of differences in risk taking and risk management in Polish SMEs companies from a gender perspective.

Materials and Methods: One hundred adults (50 male and 50 female of age 18-30 years, with Angle′s class I ideal occlusion and balanced profiles, were selected for the study. Study models were prepared and crown angulations and crown inclinations were measured using a customized protractor device. Bolton′s analysis was used to measure the tooth size discrepancies. Results: Maxillary and mandibular teeth had less crown angulations. Maxillary and mandibular incisors and maxillary molars showed increased crown inclinations, whereas mandibular molars and premolars had less crown inclinations than the original Andrews sample. The mean maxillary and mandibular tooth size ratios, overall and anterior, were similar to Bolton′s ratios. Conclusions: The finding of this study indicates that there are possible racial and ethnic factors contributing to variations in crown angulations and crown inclinations.

2013-12-01

Full Text Available Little is known about how Strategic Information Systems Planning (SISP and small and medium-sized enterprises (SMEs are linked in a developing country. SISP has also been a concern for many in the Information Technology (IT industry and IT based businesses as a whole. This research seeks to address this shortcoming by exploring what constitutes a typical SME, what role Information Systems (ISs play in SMEs and what role SISP plays in SMEs. Consequently, a Delphi panel comprising a questionnaire in the first phase and an interview in the second phase was employed. Some correlation was found to exist with the literature, with the exception of the role of IS in SMEs, whether SISP is an on-going activity, and the fact that SISP can be outsourced. Some new facts were discovered, especially on the topic of outsourcing.

2017-09-01

Full Text Available Objective: The purpose of this study is to examine whether work-life balance (WLB practices are satisfactorily provided in UK small and medium-sized enterprises (SMEs and the impact of the availability of these work-life policies on turnover intentions. A review of extant literature reveals scarce knowledge in this area of research and this study presents a rudimentary effort to fill this gap. Research Design & Methods: Using qualitative design, the data set comprised of in-depth interviews with thirty-six employees working in small and medium-sized UK convenience stores and supermarkets with less than ninety employees. Findings: Informal nature of human resource management policies emerged from the findings as one of the constraining forces impeding work-life agendas in SMEs and causing low staff retention in UK. Although other themes were found to contribute to retention challenges, however, these additional reasons were not independent, but all considered integrated. Implications & Recommendations: Consequently, the practical implication of devising ways to overcome WLB and retention deficiencies in this context were also explored. Contribution & Value Added: The originality of this work lies in studying the importance of WLB practices to some of these grass root businesses that make up a large proportion of the economy in the UK. As the limitation of this study is that it is wholly qualitative in nature, it is suggested that future research should rely on quantitative designs that provides more internally valid tests via computational techniques.

Proper work environments are important for nurses to feel motivated. We examined the associations between work motivation and job satisfaction among Japanese nurses to improve their motivation. In Japan, relatively small and medium-sized private hospitals play a central role in the healthcare industry. In the present study, the subjects were nurses working in 23 small and medium-sized private hospitals that had 65 to 326 beds. We analyzed 1,116 registered and licensed practical female nurses (average age, 38.3 years; standard deviation, 11.3 years). Many nurses with their specialized nursing skills dedicate themselves to patient care. However, many of these nurses may not be interested in contributing to their hospitals. Nurses may have different opinions regarding dedication to patient care and contribution to their hospitals. Therefore, concerning work motivation, we produced these two different items, "Nurses' dedication to patients" and "Nurses' contribution to their hospitals." We also produced our own original new job satisfaction questionnaire. We found 7 facets of job satisfaction: "Work as specialists," "Workplace safety," "Relationships with superiors," "Work-life balance," "Relationships among nurses," "Communications with physicians," and "Salary." Multiple linear regression analyses show that both "Nurses' dedication to patients" and "Nurses' contribution to their hospitals" were significantly associated with "Work as specialists." Nurses feel their jobs of protecting people's lives and health are valuable. They do not feel motivated only by money. They value the intrinsic nature of their jobs. Creating proper work environments is important for nurses to be able to work as specialists.

For any modern astronomical observatory, it is essential to have an efficient interface between the telescope and its back-end instruments. However, for small and medium-sized observatories, this requirement is often limited by tight financial constraints. Therefore a simple yet versatile and low-cost control system is required for such observatories to minimize cost and effort. Here we report the development of a modern, multipurpose instrument control system TELICS (Telescope Instrument Control System) to integrate the controls of various instruments and devices mounted on the telescope. TELICS consists of an embedded hardware unit known as a common control unit (CCU) in combination with Linux-based data acquisition and user interface. The hardware of the CCU is built around the ATmega 128 microcontroller (Atmel Corp.) and is designed with a backplane, master-slave architecture. A Qt-based graphical user interface (GUI) has been developed and the back-end application software is based on C/C++. TELICS provides feedback mechanisms that give the operator good visibility and a quick-look display of the status and modes of instruments as well as data. TELICS has been used for regular science observations since 2008 March on the 2 m, f/10 IUCAA Telescope located at Girawali in Pune, India.

Determinants of the Capital Structure of Small and Medium Sized Brazilian Enterprises

Wilson Toshiro Nakamura

2013-07-01

Full Text Available This research investigates the determinants of the capital structure of small and medium enterprises (SMEs using a unique database that includes over 19,000 Brazilian firms and spans 13 years of data. The econometric analysis employs the System Generalized Method of Moments estimator (GMM-Sys and two strong results emerge: (a profitability is negatively related to leverage, and (b asset growth is positively related to leverage. Both results are consistent with the pecking order theory of capital structure and suggest that SMEs tend to finance their expansion with debt only after exhausting their internal resources. Additionally, we find weaker evidence for the following: (a size is positively related to leverage, which can be interpreted as evidence that larger firms have more access to credit markets; (b riskier SMEs tend to be less financially leveraged, consistent with the bankruptcy cost arguments from trade-off theories; and (c the age of the firm is negatively related to financial leverage, suggesting that older SMEs may be slightly more conservative in their financing choices. Finally, the magnitude of the coefficient of lagged leverage shows the high persistence of this variable and is compatible with the hypothesis that SMEs adjust their debt/equity ratio towards a target value, although at a low speed.

Application of a parallel genetic algorithm to the global optimization of medium-sized Au-Pd sub-nanometre clusters

Science.gov (United States)

Hussein, Heider A.; Demiroglu, Ilker; Johnston, Roy L.

2018-02-01

To contribute to the discussion of the high activity and reactivity of Au-Pd system, we have adopted the BPGA-DFT approach to study the structural and energetic properties of medium-sized Au-Pd sub-nanometre clusters with 11-18 atoms. We have examined the structural behaviour and stability as a function of cluster size and composition. The study suggests 2D-3D crossover points for pure Au clusters at 14 and 16 atoms, whereas pure Pd clusters are all found to be 3D. For Au-Pd nanoalloys, the role of cluster size and the influence of doping were found to be extensive and non-monotonic in altering cluster structures. Various stability criteria (e.g. binding energies, second differences in energy, and mixing energies) are used to evaluate the energetics, structures, and tendency of segregation in sub-nanometre Au-Pd clusters. HOMO-LUMO gaps were calculated to give additional information on cluster stability and a systematic homotop search was used to evaluate the energies of the generated global minima of mono-substituted clusters and the preferred doping sites, as well as confirming the validity of the BPGA-DFT approach.

Grain-size based sea-level reconstruction in the south Bohai Sea during the past 135 kyr

Science.gov (United States)

Yi, Liang; Chen, Yanping

2013-04-01

Future anthropogenic sea-level rise and its impact on coastal regions is an important issue facing human civilizations. Due to the short nature of the instrumental record of sea-level change, development of proxies for sea-level change prior to the advent of instrumental records is essential to reconstruct long-term background sea-level changes on local, regional and global scales. Two of the most widely used approaches for past sea-level changes are: (1) exploitation of dated geomorphologic features such as coastal sands (e.g. Mauz and Hassler, 2000), salt marsh (e.g. Madsen et al., 2007), terraces (e.g. Chappell et al., 1996), and other coastal sediments (e.g. Zong et al., 2003); and (2) sea-level transfer functions based on faunal assemblages such as testate amoebae (e.g. Charman et al., 2002), foraminifera (e.g. Chappell and Shackleton, 1986; Horton, 1997), and diatoms (e.g. Horton et al., 2006). While a variety of methods has been developed to reconstruct palaeo-changes in sea level, many regions, including the Bohai Sea, China, still lack detailed relative sea-level curves extending back to the Pleistocene (Yi et al., 2012). For example, coral terraces are absent in the Bohai Sea, and the poor preservation of faunal assemblages makes development of a transfer function for a relative sea-level reconstruction unfeasible. In contrast, frequent alternations between transgression and regression has presumably imprinted sea-level change on the grain size distribution of Bohai Sea sediments, which varies from medium silt to coarse sand during the late Quaternary (IOCAS, 1985). Advantages of grainsize-based relative sea-level transfer function approaches are that they require smaller sample sizes, allowing for replication, faster measurement and higher spatial or temporal resolution at a fraction of the cost of detail micro-palaeontological analysis (Yi et al., 2012). Here, we employ numerical methods to partition sediment grain size using a combined database of

Large sources of aerosol particles and their precursors are ubiquitous in East Asia. Such sources are known to impact the South China Sea (henceforth SCS), a sometimes heavily polluted region that has been suggested as particularly vulnerable to climate change. To help elucidate springtime aerosol transport into the SCS, an intensive study was performed on the remote Dongsha (aka Pratas) Islands Atoll in spring 2010. As part of this deployment, a Davis Rotating-drum Uniform size-cut Monitor (DRUM) cascade impactor was deployed to collect size-resolved aerosol samples at the surface that were analyzed by X-ray fluorescence for concentrations of selected elements. HYSPLIT backtrajectories indicated that the transport of aerosol observed at the surface at Dongsha was occurring primarily from regions generally to the north and east. This observation was consistent with the apparent persistence of pollution and dust aerosol, along with sea salt, in the ground-based dataset. In contrast to the sea-level observations, modeled aerosol transport suggested that the westerly flow aloft (w700 hPa) transported smoke-laden air toward the site from regions from the south and west. Measured aerosol optical depth at the site was highest during time periods of modeled heavy smoke loadings aloft. These periods did not coincide with elevated aerosol concentrations at the surface, although the model suggested sporadic mixing of this free-tropospheric aerosol to the surface over the SCS. A biomass burning signature was not clearly identified in the surface aerosol composition data, consistent with this aerosol type remaining primarily aloft and not mixing strongly to the surface during the study. Significant vertical wind shear in the region also supports the idea that different source regions lead to varying aerosol impacts in different vertical layers, and suggests the potential for considerable vertical inhomogeneity in the SCS aerosol environment.

Effect of heliostat size on the levelized cost of electricity for power towers

Science.gov (United States)

Pidaparthi, Arvind; Hoffmann, Jaap

2017-06-01

The objective of this study is to investigate the effects of heliostat size on the levelized cost of electricity (LCOE) for power tower plants. These effects are analyzed in a power tower with a net capacity of 100 MWe, 8 hours of thermal energy storage and a solar multiple of 1.8 in Upington, South Africa. A large, medium and a small size heliostat with a total area of 115.56 m2, 43.3 m2 and 15.67 m2 respectively are considered for comparison. A radial-staggered pattern and an external cylindrical receiver are considered for the heliostat field layouts. The optical performance of the optimized heliostat field layouts has been evaluated by the Hermite (analytical) method using SolarPILOT, a tool used for the generation and optimization of the heliostat field layout. The heliostat cost per unit is calculated separately for the three different heliostat sizes and the effects due to size scaling, learning curve benefits and the price index is included. The annual operation and maintenance (O&M) costs are estimated separately for the three heliostat fields, where the number of personnel required in the field is determined by the number of heliostats in the field. The LCOE values are used as a figure of merit to compare the different heliostat sizes. The results, which include the economic and the optical performance along with the annual O&M costs, indicate that lowest LCOE values are achieved by the medium size heliostat with an area of 43.3 m2 for this configuration. This study will help power tower developers determine the optimal heliostat size for power tower plants currently in the development stage.

Enterprise size and risk of hospital treated injuries among manual construction workers in Denmark: a study protocol.

Science.gov (United States)

Pedersen, Betina H; Hannerz, Harald; Christensen, Ulla; Tüchsen, Finn

2011-04-21

In most countries throughout the world the construction industry continues to account for a disturbingly high proportion of fatal and nonfatal injuries. Research has shown that large enterprises seem to be most actively working for a safe working environment when compared to small and medium-sized enterprises. Also, statistics from Canada, Italy and South Korea suggest that the risk of injury among construction workers decreases with enterprise size, that is the smaller the enterprise the greater the risk of injury. This trend, however, is neither confirmed by the official statistics from Eurostat valid for EU-15 + Norway nor by a separate Danish study - although these findings might have missed a trend due to severe underreporting. In addition, none of the above mentioned studies controlled for the occupational distribution within the enterprises. A part of the declining injury rates observed in Canada, Italy and South Korea therefore might be explained by an increasing proportion of white-collar employees in large enterprises. To investigate the relation between enterprise size and injury rates in the Danish construction industry. All male construction workers in Denmark aged 20-59 years will be followed yearly through national registers from 1999 to 2006 for first hospital treated injury (ICD-10: S00-T98) and linked to data about employment status, occupation and enterprise size. Enterprise size-classes are based on the Danish business pattern where micro (less than 5 employees), small (5-9 employees) and medium-sized (10-19 employees) enterprises will be compared to large enterprises (at least 20 employees). The analyses will be controlled for age (five-year age groups), calendar year (as categorical variable) and occupation. A multi-level Poisson regression will be used where the enterprises will be treated as the subjects while observations within the enterprises will be treated as correlated repeated measurements. This follow-up study uses register data that

This research aims to improve the productivity in the rubber line of a medium-sized industry by increasing the production capacities through the use of the Aggregate Production Planning model. For this purpose an analysis of the production processes of the line was made and the aggregate plan was defined evaluating two strategies: Exact Production Plan (Zero Inventory) and Constant Workforce Plan (Vary Inventory) by studying the costs of both inventory maintenance and workforce. It was also determined how the installed capacity was used with the standards of the rubber line and measures for decreasing production costs were proposed. It was proven that only 70% of the plant capacity was being used so it could be possible to produce more units and to obtain a bigger market for the products of this line.+

Preterm birth (PB) is an important predictor of childhood morbidity and educational performance. Beyond the known risk factors, environmental factors, such as air pollution and noise, have been implicated in PB. In urban areas, these pollutants coexist. Very few studies have examined the effects of multi-exposure on the pregnancy duration. The objective of this study was to analyse the relationship between PB and environmental chronic multi-exposure to noise and air pollution in medium-sized cities. A case-control study was conducted among women living in the city of Besançon (121 671 inhabitants) or in the urban unit of Dijon (243 936 inhabitants) and who delivered in a university hospital between 2005 and 2009. Only singleton pregnancies without associated pathologies were considered. Four controls were matched to each case in terms of the mother's age and delivery location. Residential noise and nitrogen dioxide (NO2) exposures were calculated at the mother's address. Conditional logistic regression models were applied, and sensitivity analyses were performed. This study included 302 cases and 1204 controls. The correlation between noise and NO2 indices ranged from 0.41 to 0.59. No significant differences were found in pollutant exposure levels between cases and controls. The adjusted odds ratios ranged between 0.96 and 1.08. Sensitivity analysis conducted using different temporal and spatial exposure windows demonstrated the same results. The results are in favour of a lack of connection between preterm delivery and multi-exposure to noise and air pollution in medium-sized cities for pregnant women without underlying disease. © The Author 2017; all rights reserved.

The diet and trophic level (TL ) of the yellownose skate Zearaja chilensis in the south-western Atlantic Ocean (35°-54° S), and how these varied in relation to body size, sex, maturity stage, depth and region were determined by analysis of stomach contents. From 776 specimens analysed, 671 (86·5%) ranging from 180 to 1190 mm total length (LT ) had prey in their stomachs. The diet was dominated by fishes, mainly the notothenioid Patagonotothen ramsayi and the Argentine hake Merluccius hubbsi. The consumption of fishes and crabs increased with increasing predator size, and these preys were more important in the north than in the south. Isopods and other crustaceans were consumed more in the south and their consumption decreased as the size of Z. chilensis increased. The TL of Z. chilensis increased with LT from 4·29 to 4·59 (mean 4·53), confirming their ecological role as a top predator. The small and large size classes exhibited a low diet overlap and the highest spatial segregation, whereas medium and large specimens had higher co-occurrence and dietary overlap indices. A clear distinction in tooth shape was noted between sexes in adult specimens, with males having longer cusps. This sexual heterodonty may be related to reproductive behaviour, increasing the grasping ability of males during courtship, because there were no differences in diet between the sexes. © 2016 The Fisheries Society of the British Isles.

A proposed operational risk management framework for small and medium enterprises

Directory of Open Access Journals (Sweden)

Micheline J. Naude

2017-12-01

Full Text Available Background: The gap between small and medium-sized enterprises (SMEs and large businesses that perform risk assessment is significant. SMEs continuously face many operational risks and uncertainties in their daily operations, and these risks threaten to reduce productivity, increase costs and reduce profits. Aim: The purpose of this article was to develop an operational risk management framework that SMEs can use to identify and analyse risks in their operations and take corrective actions to mitigate these risks. Setting: Small and medium-sized enterprises in South Africa do not view risk management as a key component of organisational success, despite evidence that businesses that adopt risk management strategies are more likely to survive and grow. Methods: The article is exploratory in nature, and a conceptual analysis approach was used to formulate the framework. This study reviewed relevant literature sources on risk published between 2002 and 2017. Results: The four process steps of risk management were used as a reference point and form the foundation for the operational risk management framework. The categories of operational; marketing; technical and financial risks were identified from a review of available literature on risk management. Conclusion: There is a dearth of research that deals with operational risk management frameworks for SMEs. The expected contribution of this article, therefore, is twofold: firstly, it is envisaged that managers or owners of SMEs could use the proposed framework as a tool to appraise and minimise their operational risks; secondly, it will add to the current body of knowledge on risk appraisal for SMEs.

Approaches to Assess Competitiveness of Small and Medium Sized Reactors

International Nuclear Information System (INIS)

Kuznetsov, V.; Barkatullah, N.

2011-01-01

There is continuing interest in Member States concerning the development and application of small and medium sized reactors (SMRs), i.e., reactors with the equivalent electric power of less than 700 MW. Currently, developed SMRs are in most cases intended for markets different than those in which large nuclear power plants operate. Such markets have essentially different investment requirements, siting flexibility, grid connections and infrastructure restrictions. Therefore, economic factors affecting the competitiveness or competition of SMRs in such markets would also be different from those observed in established markets for electricity production. For example, investment capability may be limited, which would favour capacity addition in smaller increments; grids may be small or weak, which would favour capacities exactly matching the demand; infrastructure and human resource may be insufficient, which would favour less complex operation and maintenance requirements; and non-electrical energy products, such as potable water, may be in demand, which would favour reasonably close plant location to the customer. In practice it is futile to compare a single SMR needs to a single larger capacity plant on an economy of scale basis because SMRs are suitable for those locations that might not be appropriate for larger plants. However, a series of SMRs could be considered comparable to fewer larger plants to achieve the same overall power station capacity. In this case, SMRs have a potential to be competitive by employing alternative design strategies, taking advantage of smaller reactor size, offering a less complex design and operation and maintenance, relying on deployment-in-series approaches, taking an advantage of the accelerated learning, multiple unit factors and shorter construction duration. Reflecting on developments in member states, the International Atomic Energy Agency (IAEA) is finalizing the preparation of a report highlighting the economics and

This paper presents the results of a detailed study on the size characteristics of aerosols at the tropical coastal site Thiruvananthapuram based on the in-situ measurements of size resolved aerosol number density using an aerosol spectrometer, covering a period of 28 months from September 2011 to December 2013. The diurnal pattern of aerosol number density is characterized by day time low and a two-fold increase during nighttime and these changes are closely associated with the strong mesoscale features namely the sea breeze and land breeze prevailing at the site. Aerosol Number Size Distribution (NSD) depicts a multi-modal nature with two prominent modes, one ≤0.1 μm and other ∼1 μm. Two other less pronounced modes are also observed in the NSD, one ∼0.3-0.5 μm and other ∼5-8 μm. The NSDs also exhibited strong seasonal changes linked with the synoptic meteorological feature of this region namely the South Asian monsoon. The seasonal NSDs were parameterized and analyzed. In addition to this, the effects of meteorological parameters temperature, relative humidity, and wind speed and airflow patterns on aerosol number density as revealed by partial correlation analysis were found to be aerosol size dependent.

Full Text Available The market for enterprise systems (ESs continues to grow as business becomes increasingly global and competitive. Increasingly, the market focus for ES vendors is on small businesses. The purpose of this study is to provide a unique ES vendor/consultant perspective on (a the business benefits small and medium-sized enterprises (SMEs expect from their ES investment and (b to examine current practices of ES implementation in SMEs through a conceptual framework that considers the organisational, process and strategic context of the implementation. This study does so with interview data collected from ES vendors, ES consultants and IT research firms, who are the key players in the New Zealand ES industry. A distinctive contribution of this research is the vendor/consultant perspective as the unit of analysis, rather than the SME perspective commonly used in similar research. The vendor/consultant perspective offers a comprehensive viewpoint that extends across numerous SMEs in a variety of industries. Findings from interviews with these professionals indicate that although many ES implementations are several years old now, SMEs have only recently started tracking benefits through analytical processes in expectation to realise business value from their ES investment. The results also identify how ES implementation practices are adapting to be more suitable to the SME sector, an important market for ES vendors given the saturation of the large enterprise market for ES implementation.

This study monitored indoor and outdoor particle concentrations in 37 small and medium commercial buildings (SMCBs) in California with three buildings sampled on two occasions, resulting in 40 sampling days. Sampled buildings included offices, retail establishments, restaurants, dental offices, and hair salons, among others. Continuous measurements were made for both ultrafine and fine particulate matter as well as black carbon inside and outside of the building. Integrated PM(2.5), PM(2.5-10), and PM(10) samples were also collected inside and outside the building. The majority of the buildings had indoor/outdoor (I/O) particle concentration ratios less than 1.0, indicating that contributions from indoor sources are less than removal of outdoor particles. However, some of the buildings had I/O ratios greater than 1, indicating significant indoor particle sources. This was particularly true of restaurants, hair salons, and dental offices. The infiltration factor was estimated from a regression analysis of indoor and outdoor concentrations for each particle size fraction, finding lower values for ultrafine and coarse particles than for submicrometer particles, as expected. The I/O ratio of black carbon was used as a relative measure of the infiltration factor of particles among buildings, with a geometric mean of 0.62. The contribution of indoor sources to indoor particle levels was estimated for each building.

Bridging the energy gap through small and medium sized nuclear reactors in India

International Nuclear Information System (INIS)

Srivastava, R.

1987-01-01

India is the only country in the world which is employing small sized nuclear reactors for its nuclear power programme. It has now embarked on a programme of augmenting the contribution of the nuclear power by way of employing both medium and small sized nuclear reactors in the next 15 years. This paper discusses the Indian experience and its efforts for industrial mobilisation for rapidly constructing 235/500 MWe nuclear reactor units in a period of about 8 to 9 years. The current energy situation in India and this context the near term role of nuclear power for supplementing the existing sources of commercial energy have been evaluated. Nuclear power has reached such a stage of maturity whereby it has now become a commercially viable source of electricity and it could be utilised on large scale to bridge the energy gap. At present six reactor units of 210/235 MWe capacity are in operation and eight more are in different stages of construction. While we are continuing with the construction of 235 MWe units, a programme of being pursued to construct 550 MWe capacity reactor units from midnineties onwards. This has become possible with the strengthening of regional electricity grids and simultaneous efforts undertaken for augmentation of fuel supply, heavy water production and industrial infrastructure. For a developing country like India, implementation of a sizable nuclear power programme has posed certain special challenges as major inputs are required to be made available with indigeneous efforts. This paper discusses such challenges and presents the ways and means adopted to surmount them. Other developing countries with conditions comparable to those in India could benefit from Indian experience in this regard. This paper also proposes India's willingness to cooperate with other countries for exchange of information and assistance in terms of technical knowhow. (author)

Presenting a Framework to Analyze Local Climate Policy and Action in Small and Medium-Sized Cities

Thomas Hoppe

2016-08-01

Full Text Available Academic attention to local climate policy usually focuses on large-sized cities. Given the climate challenges ahead this seems unjustified. Small and medium-sized cities (SMCs deserve scholarly attention as well. The main question is: What factors influence climate change policy and local climate actions in SMCs? In this article we present an analytical framework to analyze climate change policy and local climate actions of SMCs. The framework addresses different aspects: policy-input, -throughput, -output, -outcome, characteristics of the local environment, local action arenas, influence by higher government levels, and interaction with climate change issue networks. The framework is used to analyze and compare four case studies of SMCs in the Dutch region of Twente (two urban and two rural municipalities, and addresses both adaptation and mitigation. Results show that both ‘localist’, ‘multi-level’ and issue network membership factors influence local climate policy action. Governance modes discerned concern mostly ‘governing by authority’ and ‘self-governing’. When reflecting on the role of SMCs in climate action the study revealed the importance of local capacity building schemes issued by provincial government, inter-municipal network collaboration, and the potential for local governments to mobilize and organize citizen action.

Gamage Pandula

2015-08-01

Full Text Available Access to bank finance is necessary to create an economic environment that enables Small and Medium-sized enterprises (SMEs to grow and prosper. The SMEs in Sri Lanka, however, face significant constraints to access bank finance. The purpose of this paper is to investigate the access to bank finance and related issues in the SME sector of Sri Lanka. The paper is exploratory in nature and reviews the bank financing situation for SMEs in Sri Lanka, as well as provides an overview of constraints faced by the banks (supply-side and SMEs (demand-side. The paper also highlights some good practices in SME lending from international experience and outlines some recommendations to help overcome the constraints faced by the banks and SMEs. The recommendations discussed in this paper may be of importance to policymakers, not only in Sri Lanka, but in many other developing countries in a similar stage of economic growth.

The impact of SMEs’ lending and credit guarantee on bank efficiency in South Korea

Directory of Open Access Journals (Sweden)

Lien-Wen Liang

2017-12-01

Full Text Available This study examines how small and medium-size enterprises’ (SMEs’ lending and credit guarantee affect Korean banks’ efficiency, by employing the stochastic frontier approach on 14 banks over the period 2001–2010. When lending increases to SMEs, the findings indicate that banks’ cost efficiency decreases due to information asymmetry. However, the increased proportion of credit guarantee can improve their cost efficiency. This proves that South Korea’s credit guarantee system can indeed share SMEs’ credit risk of lending in order to help raise bank efficiency.

2018-01-01

This study investigates the benefits and limits deriving from membership with ESA of six medium-sized space agencies in terms of strengthening and development (or not) of space technologies, as well as their contribution to the growth of productive activities and to the increase of services for citizens. This research contributes to the more general issue of the usefulness of space activities, not only for scientific or military-political purposes but also for economic and social development. Results show that, on the one hand, the membership with ESA has allowed smaller Countries to access space programs, to develop advanced technologies and to support the growth of their firms in some significant markets, but, on the other hand, the membership has also limited the access to space to few companies, without encouraging the broad dissemination of technological knowledge.

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.

Full Text Available Purpose: The present paper aims at developing an effective framework including all the components necessary for implementing lean production properly in Small and Medium-sized Enterprises. Design/methodology/approach: The paper begins with the review of the main existing framework of lean implementation in order to highlight shortcomings in the literature through a lack of suitable framework for small companies. To overcome this literature gap, data of successful initiatives of lean implementation were collected based on a multiple case study approach. These initiatives has been juxtaposed in order to develop a new, practical and effective framework that includes all the components (process, tools, success factors that are necessary to implement lean in Small and Medium-sized Enterprises. Findings: The proposed framework presents many significant contributions: First, it provides an overcoming for the limitations of the existing frameworks by proposing for consultants, researchers and organizations an effective framework for lean implementation in SMEs that allows SMEs to benefit from competitive advantages  gained by lean. Second, it brings together a set of the more essential and critical elements of lean implementation commonly used by SMEs and derived from the practical experiences of them in lean implementation. Finally, it highlights the successful experiences of small companies in implementing lean programs and then proves that lean can give a relevant results even for SMEs. Research limitations/implications: The proposed framework presents a number of limitations and still evokes extension for further researches: Although it was derived from practical experiences of SMEs, the proposed framework is not supported by practical implementation. On the other hand and even though the elements in the proposed framework from the practical experiences of four SMEs, the identified elements need to be generalized and enriching by conducting

Not enough space for everyone: China and the competition for the Global South

Directory of Open Access Journals (Sweden)

Fernando Mouron

2016-12-01

Full Text Available A little more than a decade and a half into the “Asian century”, the epicentre of the global economy has moved from the North Atlantic towards East Asia at an unprecedented pace. As a correlate, China’s growing expansion at global level has been gradually undermining the position of leading regional powers such as Brazil and South Africa. The displacement of their investments and the consequent loss of their regional markets, added to the growth of other medium-sized regional powers through stronger links with Beijing, have damaged both countries prospects of regional leadership. From this perspective, in contrast to the abundant literature depicting China as a great opportunity for Brazil and South Africa, this paper warns that both countries’ regional importance has been diminished in favour of China, which calls the usefulness of the BRICS concept into question.

2016-01-01

The increasing number of nanotechnology products on the market poses increasing human health risks by particle exposures. Adverse effects of silver nanoparticles (AgNPs) in various cell lines have been measured based on exposure dose after a fixed time point, but NP uptake kinetics and the time-dependent internal cellular concentration are often not considered. Even though knowledge about relevant timescales for NP uptake is essential, e.g. for time- and cost-effective risk assessment through modelling, insufficient data are available. Therefore, the authors examined uptake rates for three different AgNP sizes (20, 50 and 75 nm) and two tissue culture medium compositions (with and without foetal calf serum, FCS) under realistic exposure concentrations in pulmonary epithelial 16HBE14o-cells. The quantification of Ag in cells was carried out by high-resolution inductively coupled plasma mass spectrometry. We show for the first time that uptake kinetics of AgNPs into 16HBE14o-cells was highly influenced by medium composition. Uptake into cells was higher in medium without FCS, reaching approximately twice the concentration after 24 h than in medium supplemented with FCS, showing highest uptake for 50-nm AgNPs when expressed on a mass basis. This optimum shifts to 20 nm on a number basis, stressing the importance of the measurand in which results are presented. The importance of our research identifies that not just the uptake after a certain time point should be considered as dose but also the process of uptake (timing) might need to be considered when studying the mechanism of toxicity of nanoparticles.

The aim of this meta-analysis is to examine synthesized correlation outcomes between maltreatment, witnessing domestic violence, and bullying among youths in South Korea. The study examined 42 studies from between 2000 and 2015; the results showed that there is a medium effect size for this association among youths. Specifically, the effect size of the association was found to be larger for physical and verbal/emotional abuse and neglect than exposure to domestic violence for youths. The authors suggest that effective prevention and intervention for youths who are at risk of suffering maltreatment and witnessing domestic violence may help them avoid developing bullying behaviors.

Fine needles with an end hole or multiple side holes have traditionally been used for percutaneous ethanol injection (PEI) of hepatomas. This study retrospectively evaluates the safety and efficacy of PEI of unresectable medium-to-large (3.5-9 cm) hepatomas using a multipronged needle and with conscious sedation. Twelve patients, eight men and four women (age 51-77 years; mean: 69) received PEI for hepatomas, mostly subcapsular or exophytic in location with average tumor size of 5.6 cm (range: 3.5-9.0 cm). Patients were consciously sedated and an 18G retractable multipronged needle (Quadrafuse needle; Rex Medical, Philadelphia, PA) was used for injection under real-time ultrasound guidance. By varying the length of the prongs and rotating the needle, the alcohol was widely distributed within the tumor. The progress of ablation was monitored by contrast-enhanced ultrasound, computed tomography (CT) or magnetic resonance imaging (MRI) after each weekly injection and within a month after the final (third) injection and 3 months thereafter. An average total of 63 mL (range: 20-154 ml) of alcohol was injected per patient in an average of 2.3 sessions. Contrast-enhanced CT, ultrasound, or MRI was used to determine the degree of necrosis. Complete necrosis was noted in eight patients (67%), near-complete necrosis (90-99%) in two (16.7%), and partial success (50-89%) in two (16.7%). Follow-up in the first 9 months showed local recurrence in two patients and new lesions in another. There was no mortality. One patient developed renal failure, liver failure, and localized perforation of the stomach. He responded to medical treatment and surgery was not required for the perforation. One patient had severe postprocedural abdominal pain and fever, and another had transient hyperbilirubinemia; both recovered with conservative treatment. PEI with a multipronged needle is a new, safe, and efficacious method in treating medium-to-large-sized hepatocellular carcinoma under conscious

Small-medium sized nuclear coal and gas power plant: A probabilistic analysis of their financial performances and influence of CO2 cost

International Nuclear Information System (INIS)

Locatelli, Giorgio; Mancini, Mauro

2010-01-01

Nations or regions with limited electrical grid and restricted financial resources are a suitable market for small medium power plants with a size of 300-400 MWe. The literature presents several comparisons about the economics of large power plants (of about 1000 MWe); however there are not probabilistic analysis regarding the economics of small medium power plants. This paper fills this gap comparing, with a Monte Carlo evaluation, the economical and financial performances of a nuclear reactor, a coal fired power plant and a combined cycle gas turbine (CCGT) of 335 MWe. The paper aims also to investigate the effect of the carbon tax and electrical energy price on the economics of these plants. The analysis show as, without any carbon tax, the coal plant has the lowest levelised unit electricity cost (LUEC) and the highest net present value (NPV). Introducing the carbon tax the rank changes: depending on its amount the first and the nuclear after becomes the plant with lower LUEC and highest NPV. Therefore, the uncertainty in the carbon tax cost increases the risk of investing in a coal plant above the level of the new small medium reactor.

Deforestation continues across the tropics at alarming rates, with repercussions for ecosystem processes, carbon storage and long term sustainability. Taking advantage of recent fine-scale measurement of deforestation, this analysis aims to improve our understanding of the scale of deforestation drivers in the tropics. We examined trends in forest clearings of different sizes from 2000-2012 by country, region and development level. As tropical deforestation increased from approximately 6900 kha yr-1 in the first half of the study period, to >7900 kha yr-1 in the second half of the study period, >50% of this increase was attributable to the proliferation of medium and large clearings (>10 ha). This trend was most pronounced in Southeast Asia and in South America. Outside of Brazil >60% of the observed increase in deforestation in South America was due to an upsurge in medium- and large-scale clearings; Brazil had a divergent trend of decreasing deforestation, >90% of which was attributable to a reduction in medium and large clearings. The emerging prominence of large-scale drivers of forest loss in many regions and countries suggests the growing need for policy interventions which target industrial-scale agricultural commodity producers. The experience in Brazil suggests that there are promising policy solutions to mitigate large-scale deforestation, but that these policy initiatives do not adequately address small-scale drivers. By providing up-to-date and spatially explicit information on the scale of deforestation, and the trends in these patterns over time, this study contributes valuable information for monitoring, and designing effective interventions to address deforestation.

We study spatial meson correlation functions consisting of strange quarks, strange and charm quarks and charm quarks in (2 + 1)-flavor QCD using the highly improved staggered quark action. We find that the in-medium modification of the meson correlators decreases with increasing charm quark content and decreasing size. In particular, we find strong in-medium modification of φ and D s meson correlators around the chiral transition temperature T c , while J/ψ and η c correlators show strong in-medium modification only at temperatures of 1.4T c .

The natural selection of organizational and safety culture within a small to medium sized enterprise (SME).

Brooks, Benjamin

2008-01-01

Small to Medium Sized Enterprises (SMEs) form the majority of Australian businesses. This study uses ethnographic research methods to describe the organizational culture of a small furniture-manufacturing business in southern Australia. Results show a range of cultural assumptions variously 'embedded' within the enterprise. In line with memetics - Richard Dawkin's cultural application of Charles Darwin's theory of Evolution by Natural Selection, the author suggests that these assumptions compete to be replicated and retained within the organization. The author suggests that dominant assumptions are naturally selected, and that the selection can be better understood by considering the cultural assumptions in reference to Darwin's original principles and Frederik Barth's anthropological framework of knowledge. The results are discussed with reference to safety systems, negative cultural elements called Cultural Safety Viruses, and how our understanding of this particular organizational culture might be used to build resistance to these viruses.

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

Increasing interest towards reducing greenhouse gas (GHG) emissions from biological processes has resulted in researchers using this method to quantify N 2 O and CO 2 concentrations in the off-gas. Experimental measurements of direct GHG emissions from aerobic digesters (AeDs) are not available in literature yet. In this study, the floating hood technique was used for the first time to monitor AeDs. The floating hood technique was used to evaluate oxygen transfer rates in an activated sludge (AS) tank of a medium-sized municipal wastewater treatment plant located in Italy. Very low values of oxygen transfer efficiency were found, confirming that small-to-medium-sized plants are often scarcely monitored and wrongly managed. Average CO 2 and N 2 O emissions from the AS tank were 0.14 kg CO2 /kg bCOD and 0.007 kg CO2,eq /kg bCOD , respectively. For an AeD, 3 × 10 -10  kg CO2 /kg bCOD direct CO 2 emissions were measured, while CO 2,eq emissions from N 2 O were 4 × 10 -9  kg CO2,eq /kg bCOD . The results for the AS tank and the AeD were used to estimate the net carbon and energy footprint of the entire plant.

The author developed a computer program for use in registration, monthly statistics, printing of reports, data storage and retrieval in the Radiology department. This program has been used in the Department of Radiology, MoonHwa Hospital since November 1990. This program was written in FoxBASE language, consisted of two independent subprograms, one installed in a registration computer without a printer and another in a reporting computer with a printer. The subprograms were designed to link their data by floppy disk. Each computer's hard disk contained permanent files for retrieval and temporary files for data input. All permanent files were indexed on several keywords including the patient's identification data. 1. Registration was performed easily and rapidly. 2. A monthly statistic was obtained simply. 3. Retrieval of the results of previous radiologic studies, printing of report, storage and indexing of data were achieved automatically. This program had merits of simple operation, large storage capacity, rapid retrieval speed, relative low price, easy adjustment for other hospitals. Therefore this program is considered to be an economic substitute for computerization of radiology departmental management in medium sized hospitals

Boniface Okanga

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.

Effective medium theory for anisotropic metamaterials

KAUST Repository

Zhang, Xiujuan

2015-01-20

Materials with anisotropic material parameters can be utilized to fabricate many fascinating devices, such as hyperlenses, metasolids, and one-way waveguides. In this study, we analyze the effects of geometric anisotropy on a two-dimensional metamaterial composed of a rectangular array of elliptic cylinders and derive an effective medium theory for such a metamaterial. We find that it is possible to obtain a closed-form analytical solution for the anisotropic effective medium parameters, provided the aspect ratio of the lattice and the eccentricity of the elliptic cylinder satisfy certain conditions. The derived effective medium theory not only recovers the well-known Maxwell-Garnett results in the quasi-static regime, but is also valid beyond the long-wavelength limit, where the wavelength in the host medium is comparable to the size of the lattice so that previous anisotropic effective medium theories fail. Such an advance greatly broadens the applicable realm of the effective medium theory and introduces many possibilities in the design of structures with desired anisotropic material characteristics. A real sample of a recently theoretically proposed anisotropic medium, with a near-zero index to control the flux, is achieved using the derived effective medium theory, and control of the electromagnetic waves in the sample is clearly demonstrated.

Small and medium reactors: Development status and application aspects

International Nuclear Information System (INIS)

Kupitz, J.

2001-01-01

During the 1960s and the early 1970s. the nuclear power plants entering service were dominated by plants with outputs falling into the small (less than 150 W e ) and medium (300 MWe to 700 MWe) reactor size ranges. During the late 1970s and 1980s, the balance shifted to large size plants (900 MWe to 1400 MWe), as nuclear power plants entered service, predominately, to serve the requirements of industrialized countries such as the US, Japan, Germany, and France. However, in the 1990s, the pendulum has swung back in the direction of small and medium sized reactors; currently 65% of the nuclear power plants under construction fall into the small and medium reactor size ranges. This shift has resulted from a sharp reduction in the number of nuclear power plants being built in the industrialized countries, in combination with the continued construction of small and medium sized nuclear power plants in developing countries such as India. China, Pakistan, and Slovakia. Developing countries are often characterized by limited capacity electrical grid systems. limited financial capability, and rapidly expanding energy demand requirements. In addition, most of the developing countries in which rapid increases in population and energy demand are occurring have few or very limited indigenous energy resources. These countries are therefore very interested in acquiring energy sources (for electricity production and process heat) that can serve the needs of their people and industries, and which do not overburden their financial capabilities (balance of payments, national debt load. etc.). It is therefore not surprising that many developing countries have, particularly during the late 1990s, expressed an interest in small and medium sized nuclear power plants (SMRs). The requirements for SMRs often cited by developing countries include low absolute capital cost, short construction schedule, favourable economic operation, and infrastructure requirements within the technical and

Full Text Available Small and Medium-sized Enterprises (SMEs contribute much to job creation, poverty eradication, economic development and growth. Countries rely on SMEs for wealth creation and social wellbeing of their citizens. Moreover, SMEs contribute to the global competitiveness of a country. For SMEs to continue offering all these benefits to the country, they must be competitive in the midst of global competitive pressure. To gain competitive advantage, enterprises of different sizes practice Competitive Intelligence (CI. While CI practise has been widely researched in large enterprise, there is lack of CI practice research in SMEs. This research establishes the impact of business type and sector, location and annual turnover on the competitive intelligence practise of SMEs. The research was quantitative in nature and a self-administered questionnaire was used to collect data from owners/managers of SMEs.

Software-as-a-Service and Cloud Computing, a solution for small and medium-sized companies

Bajenaru, A.

2010-12-01

Full Text Available Small and medium-sized companies are an important part of today’s world economy, for their ability to offer new jobs but also for their capacity of innovation. At the same time, they are in a constant struggle with larger companies that take advantage of their negotiating power to impose their way of doing business to the SMEs. In an ICT enabled world, most large companies being intense ICT users, the lag of ICT adoption in SMEs may create a strong barrier between SMEs and large companies, promoting an over growing digital divide, the SMEs being in danger of being left out in some economic sectors. This paper aims at finding a possible solution in the Software-as-a-Service and Cloud Computing model, a rather new solution, yet more and more sought off by SMEs but also larger companies, especially considering the global financial and economic crisis, as well as evaluating the European Union’s main views and policies regarding the SAAS – Cloud model.

Enterprise size and risk of hospital treated injuries among manual construction workers in Denmark: a study protocol

Science.gov (United States)

2011-01-01

Background In most countries throughout the world the construction industry continues to account for a disturbingly high proportion of fatal and nonfatal injuries. Research has shown that large enterprises seem to be most actively working for a safe working environment when compared to small and medium-sized enterprises. Also, statistics from Canada, Italy and South Korea suggest that the risk of injury among construction workers decreases with enterprise size, that is the smaller the enterprise the greater the risk of injury. This trend, however, is neither confirmed by the official statistics from Eurostat valid for EU-15 + Norway nor by a separate Danish study - although these findings might have missed a trend due to severe underreporting. In addition, none of the above mentioned studies controlled for the occupational distribution within the enterprises. A part of the declining injury rates observed in Canada, Italy and South Korea therefore might be explained by an increasing proportion of white-collar employees in large enterprises. Objective To investigate the relation between enterprise size and injury rates in the Danish construction industry. Methods/Design All male construction workers in Denmark aged 20-59 years will be followed yearly through national registers from 1999 to 2006 for first hospital treated injury (ICD-10: S00-T98) and linked to data about employment status, occupation and enterprise size. Enterprise size-classes are based on the Danish business pattern where micro (less than 5 employees), small (5-9 employees) and medium-sized (10-19 employees) enterprises will be compared to large enterprises (at least 20 employees). The analyses will be controlled for age (five-year age groups), calendar year (as categorical variable) and occupation. A multi-level Poisson regression will be used where the enterprises will be treated as the subjects while observations within the enterprises will be treated as correlated repeated measurements

2014-07-01

Full Text Available In this study family-related factors that can influence the succession process in small and medium-sized family businesses are empirically investigated.  The dependent variable in this study is measured by two underlying dimensions, namely satisfaction with the process and continued profitability of the business.  The empirical results indicate that the family-related factors that influence both the aforementioned dimensions are the mutual acceptance of roles, the relationship between the owner-manager and successor, and family harmony.  The continued profitability of the business is also influenced by the agreement to continue the business. The existence of family harmony in itself influences the relationship between the owner-manager and successor, the agreement to continue the business, as well as the mutual acceptance of roles.  The managerial implications of these empirical findings are discussed and recommendations offered.

Ebrahimi, Farzad; Barati, Mohammad Reza

2016-10-01

This paper investigates the thermal stability of magneto-electro-thermo-elastic functionally graded (METE-FG) nanoplates based on the nonlocal theory and a refined plate model. The METE-FG nanoplate is subjected to the external electric potential, magnetic potential and different temperature rises. Interaction of elastic medium with the METE-FG nanoplate is modeled via Winkler-Pasternak foundation model. The governing equations are derived by using the Hamilton principle and solved by using an analytical method to determine the critical buckling temperatures. To verify the validity of the developed model, the results of the present work are compared with those available in the literature. A detailed parametric study is conducted to study the influences of the nonlocal parameter, foundation parameters, temperature rise, external electric and magnetic potentials on the size-dependent thermal buckling characteristics of METE-FG nanoplates.

An Initial Implementation of Multiagent Simulation of Travel Behavior for a Medium-Sized City in China

Directory of Open Access Journals (Sweden)

Chengxiang Zhuge

2014-01-01

Full Text Available Since the traditional four-step model is so simple that it cannot solve complex modern transportation problems, microsimulation is gradually applied for transportation planning and some researches indicate that it is more compatible and realistic. In this paper, a framework of agent-based simulation of travel behavior is proposed, which is realized by MATSim, a simulation tool developed for large-scale agent-based simulation. MATSim is currently developed and some of its models are under training, so a detailed introduction of simulation structure and preparation of input data will be presented. In practice, the preparation process differs from one to another in different simulation projects because the available data for simulation is various. Thus, a simulation of travel behavior under a condition of limited available survey data will be studied based on MATSim; furthermore, a medium-sized city in China will be taken as an example to check whether agent-based simulation of travel behavior can be successfully applied in China.

Zytoon, Mohamed A; Basahel, Abdulrahman M

2017-02-24

Although marine fishing is one of the most hazardous occupations, research on the occupational safety and health (OSH) conditions aboard marine fishing vessels is scarce. For instance, little is known about the working conditions of vulnerable groups such as young and aging fishermen. The objective of the current paper is to study the OSH conditions of young and aging fishermen compared to middle-aged fishermen in the small- and medium-size (SM) marine fishing sector. A cross-sectional study was designed, and 686 fishermen working aboard SM fishing vessels were interviewed to collect information about their safety and health. The associations of physical and psychosocial work conditions with safety and health outcomes, e.g., injuries, illnesses and job satisfaction, are presented. The results of the current study can be utilized in the design of effective accident prevention and OSH training programs for the three age groups and in the regulation of working conditions aboard fishing vessels.

Full Text Available The diversity of Brazilian vertebrates is regarded among the highest in the world. However, the biologicaldiversity is still mostly unknown and a good part of it is seriously threatened by human activities. This study aimed toinventory the medium and large size mammals present in the Reserva Biológica de Santa Rita do Sapucaí, an Atlanticforest reserve located in Santa Rita do Sapucaí, southeastern Brazil. Sand-plots, photographic traps and searches foranimal tracks on pre-existent trails in the area, were carried out once every two months between May 2006 andFebruary 2007. The sand-plots and tracks were inspected during five consecutive days per sampling. We obtained 108records of 15 species, mostly of carnivorans. Two confirmed species are threatened with extinction in Brazil (Callithrixaurita and Leopardus pardalis. The results suggest that the sampled reserve has high species richness and plays animportant role in conservation of mammals in this landscape, including species threatened with extinction.

Proposal for the CEA/DRN activity on small and medium size reactors research on threshold effects

Fiorini, G.L.

1998-01-01

The discussion on Small and Medium Size Reactors - SMR is difficult considering the presumptions, justified or not, that affect the debate. Nevertheless, within this context, the CEA/DRN/DER generic objective is the achievement of an exhaustive identification and assessment of the problems that are specific for the SMR. The paper shows the proposals for the activities that are actually under discussion at the CEA/DRN. Among these activities, the research on threshold effects is an essential stage in the assessment of the choices in innovative concepts. This research, as well as the assessment itself, must cover, in an exploratory way, the aspects of operation, safety, economy, fuel cycle, etc. Before starting or, in some cases, continuing this research work, it seems interesting to define a general outline which, by systematising the approach, provides a helpful tool to the designer. The document is a potential starting point (among others) for the discussions. (author)

Olinski Marian

2016-09-01

Full Text Available The purpose of this paper is to assess the impact of grants received by companies on the formation of a business model. The study covered micro, small and medium-sized enterprises based in rural areas, which received support in the form of investment grants within the Regional Operational Programmes 2007-2013 for northern Poland. The research was done using a direct survey method, and covered a total of 155 companies. The results of the study indicate that the grant obtained affected implicitly the modification of the business model elements that are placed on the left side of the template of the Business Model Canvas. However, the tendency of enterprises to undertake an innovative activity usually means changes in their business model both on the left and right side. The greatest strength of the dependence was observed in the case of relationship between the size of the company and changes in the model elements. Mediumsized enterprises were the most active in this respect, when compared to comparison to micro and small businesses, and changed the largest number of elements of the business model due to the obtained grant.

Bliesner, Anna; Liedtke, Christa; Rohn, Holger

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.

IAEA Expands International Cooperation on Small, Medium Sized or Modular Nuclear Reactors

International Nuclear Information System (INIS)

2018-01-01

The International Atomic Energy Agency (IAEA) is launching an effort to expand international cooperation and coordination in the design, development and deployment of small, medium sized or modular reactors (SMRs), among the most promising emerging technologies in nuclear power. Significant advances have been made on SMRs, some of which will use pre-fabricated systems and components to shorten construction schedules and offer greater flexibility and affordability than traditional nuclear power plants. With some 50 SMR concepts at various stages of development around the world, the IAEA is forming a Technical Working Group (TWG) to guide its activities on SMRs and provide a forum for Member States to share information and knowledge, IAEA Deputy Director General Mikhail Chudakov said. “Innovation is crucial for nuclear power to play a key role in decarbonising the energy sector,” Chudakov, who heads the IAEA Department of Nuclear Energy, said at a conference on SMRs in Prague on 15 February. “Many Member States that are operating, expanding, introducing or considering nuclear power are quite keen on the development and deployment of SMRs.” Global interest in SMRs is growing. SMRs have the potential to meet the needs of a wide range of users and to be low carbon replacements for ageing fossil fuel fired power plants. They also display enhanced safety features and are suitable for non-electric applications, such as cooling, heating and water desalination. In addition, SMRs offer options for remote regions with less developed infrastructure and for energy systems that combine nuclear and alternative sources, including renewables.

The main objective of this work was to evaluate the impact of urban development trends in mobility patterns of a medium sized Portuguese city and air quality consequences, using a sequential modeling process, comprising i) land use and transportation, TRANUS model; ii) road traffic air pollutants emissions, TREM model and; iii) air quality, TAPM model. This integrated methodology was applied to a medium sized Portuguese city. In order to evaluate the implementation of the methodology, a preliminary study was performed, which consisted on the comparison of modeled mobility patterns and CO and PM(10) concentrations with measured data used in the definition of the current scenario. The comparison between modeled and monitored mobility patterns at the morning peak hour for a weekday showed an RMSE of 31%. Regarding CO concentrations, an underestimation of the modeled results was observed. Nevertheless, the modeled PM(10) concentrations were consistent with the monitored data. Overall, the results showed a reasonable consistency of the modeled data, which allowed the use of the integrated modeling system for the study scenarios. The future scenarios consisted on the definition of different mobility patterns and vehicle technology characteristics, according to two main developing trends: (1) "car pooling" scenario, which imposes a mean occupancy rate of 3 passengers by vehicle and (2) the "Euro 6" scenario, which establishes that all vehicles accomplish at least the Euro 6 standard technology. Reductions of 54% and 83% for CO, 44% and 95% for PM(10), 44% and 87% for VOC and 44% and 79% for NO(x) emissions were observed in scenarios 1 and 2, respectively. Concerning air quality, a reduction of about 100 μg m(-3) of CO annual average concentration was observed in both scenarios. The results of PM(10) annual concentrations showed a reduction of 1.35 μg m(-3) and 2.7 μg m(-3) for scenarios 1 and 2 respectively. Copyright © 2010 Elsevier B.V. All rights reserved.

Full Text Available Knowledge on the extent of linkage disequilibrium (LD in livestock populations is essential to determine the minimum distance between markers required for effective coverage when conducting genome-wide association studies. This study evaluated the extent of LD, persistence of allelic phase and effective population size (Ne for four Sanga cattle breeds in South Africa including the Afrikaner (n=44, Nguni (n=54, Drakensberger (n=47 and Bonsmara breeds (n=46, using Angus (n=31 and Holstein (n=29 as reference populations. We found that moderate LD extends up to inter-marker distances of 40-60 kb in Angus (0.21 and Holstein (0.21 and up to 100 kb in Afrikaner (0.20. This suggests that genomic selection and association studies performed within these breeds using an average inter-marker r2 ≥ 0.20 would require about 30,000 -50,000 SNPs. However, r2 ≥ 0.20 extended only up to 10-20 kb in the Nguni and Drakensberger and 20-40 kb in the Bonsmara indicating that 75,000 to 150,000 SNPs would be necessary for genome-wide association studies in these breeds. Correlation between alleles at contiguous loci indicated that phase was not strongly preserved between breeds. This suggests the need for breed-specific reference populations in which a much greater density of markers should be scored to identify breed specific haplotypes which may then be imputed into multi-breed commercial populations. Analysis of effective population size based on the extent of LD, revealed Ne=95 (Nguni, Ne=87 (Drakensberger, Ne=77 (Bonsmara and Ne=41 (Afrikaner. Results of this study form the basis for implementation of genomic selection programs in the Sanga breeds of South Africa.

However,contribution of Malaysian SMEs to economy is not up to themark to selectedbenchmarking countries such as South Korea and Japan. One of major reasons isfinancial constraint. Given that theresource of financial assistance fromgovernment is limited, concentration has tobe given to potential firms which arelisted as Enterprise 50 (E50. E50 is a prestigious awards program to recognizethe achievements of SMEs. Panel data analysis has been used to test thedeterminants of capital structure, indicatedby the leverage ratio of the firms. Theindependent variables are asset tangibility, profitability, non-debt tax shield,liquidity, age and size. Evaluation isbased on financial data of 285 firmsconsisting of 91 SMEs and 194 large firms for a period of 2004 till 2011. TradeOff and Pecking Order theory are discussed. The result shows that capitalstructure of SMEs and large firms are almost similar except in term of growth,liquidity and size. Growth is important for large firms. Liquidity is the criticalfactor for SMEs in determining short term debt, and size does matter to SMEs.

A small-to-medium-sized boiling water reactor (BWR) with a natural circulation system is being developed for countries where initial investment funds for construction are limited and electricity transmission networks have not been fully constructed. To lighten operators' work load, a core that does not use control rods during normal operation (control rod-free core) was developed by using a neutronics calculation system coupled with core flow evaluation. The control rod-free core had large core power fluctuation with conventional burnable poison design. The target of core power fluctuation was set to less than 10% and was achieved by optimization of burnable poison arrangement. (author)

Full Text Available The challenges that business face in sustaining competitive advantage in the corporate world have become a major concern. Businesses are adopting cutting-edge technologies and best practices to cope with rapid, global changes. Various business functions are being reengineered for this purpose. Accounting functions play an important role in helping businesses to maintain competitive advantage. However, some small and medium-sized enterprises (SMEs face problems handling fundamental accounting functions. This is predominantly because of their lack of expertise; accounting functions require not only knowledge of generally accepted accounting rules or tax regulations but also the expertise needed to apply the rules in a given business environment (Everaert, Sarens and Rommel, 2006. This paper offers some insight on the outsourcing of accounting functions as there is paucity of data in this area in the context of Malaysia. Essentially, it presents empirical evidence regarding Malaysian SMEs' accounting outsourcing practices. A survey of SMEs was conducted to identify the overall outsourcing landscape as it relates to accounting and third-party organisations. The factors that contribute to the decision to outsource accounting functions are analysed. The study reveals a significant relationship between outsourcing accounting functions and two contributing factors, risks and operation management.

Key Supplier Relationship Management: The Case of Croatian Medium-Sized and Large Manufacturing Companies

Dario Miočević

2011-06-01

Full Text Available The key supplier relationship management represents a vital organizational process. Companies should pay attention not only to managing customer relationships but also to managing relationships with suppliers in order to perform well. They should identify the extent to which a certain supplier adds value through the procurement process. In this line of reasoning, both theory and practice make a distinction between strategic (key and non-strategic (transactional suppliers. By employing the segmentation of the supply market, companies balance their supplier portfolio and are capable of identifying the key suppliers. They can also develop specific programs and initiatives that are aimed at preserving these relationships. In the empirical part of the paper, a survey was conducted on a sample of 123 medium-sized and large Croatian manufacturing companies. The structural model involving the relationship between the key supplier relationship management and value-oriented purchasing was tested. The results indicate that there is a statistically direct, positive and significant relationship between these two constructs. Likewise, the results stress that a theoretical conceptualization and operationalization of the key supplier relationship management construct is both valid and justified. Finally, the theoretical and practical implications and limitations of this study are offered.

To analyze the associations between sex and age with behaviour related to physical activity practice and sedentary behaviour in children and adolescents. A cross-sectional study with 480 (236 boys) subjects enrolled in a public school in the city of Londrina, in the south of Brazil, aged 8-17 years. Measures of physical activity, sports practice and screen times were obtained using the Physical Activity Questionnaire for Older Children. The Mann-Whitney U test was used to compare variables between boys and girls. The Chi squared test was used for categorical analysis and Poisson regression was used to identify prevalence. Girls (69.6%; PR=1.05 [0.99-1.12]) spent more time with sedentary behaviour than boys (62.2%). Boys (80%; PR=0.95 [0.92-0.98]) were more physically active than girls (91%). Older students aged 13-17 showed a higher prevalence of physical inactivity (91.4%; PR=1.06 [1.02-1.10]) and time spent with sedentary behaviour of ≥2h/day (71.8%; PR=0.91 [0.85-0.97]) when compared to younger peers aged 8-12 (78.7 and 58.5%, respectively). The prevalence of physical inactivity was higher in girls. Older students spent more screen time in comparison to younger students. Copyright © 2016 Sociedade de Pediatria de São Paulo.

2016-06-01

Full Text Available An air-conditioned coach is an important form of transportation in modern motorized society; as a result, there is an increasing concern of in-vehicle air pollution. In this study, we aimed to identify and quantify the levels of volatile organic compounds (VOCs and carbonyl compounds (CCs in air samples collected from the cabins of newly produced, medium- and large-size coaches. Among the identified VOCs and CCs, toluene, ethylbenzene, xylene, formaldehyde, acetaldehyde, acrolein/acetone, and isovaleraldehyde were relatively abundant in the cabins. Time was found to affect the emissions of the contaminants in the coaches. Except for benzaldehyde, valeraldehyde and benzene, the highest in-vehicle concentrations of VOCs and CCs were observed on the 15th day after coming off the assembly line, and the concentrations exhibited an approximately inverted U-shaped pattern as a function of time. Interestingly, this study also showed that the interior temperature of the coaches significantly affected the VOCs emissions from the interior materials, whereas the levels of CCs were mainly influenced by the relative humidity within the coaches. In China, guidelines and regulations for the in-vehicle air quality assessment of the coaches have not yet been issued. The results of this study provide further understanding of the in-vehicle air quality of air-conditioned coaches and can be used in the development of both specific and general rules regarding medium- and large-size coaches.

As a result of economic reform commencing in 1978 in China, cultural beliefs of the Chinese business owners are changing. While much has been published concerning large and multinational businesses, there is a gap in knowledge Of cultural beliefs of small and medium sized enterprises. To provide new knowledge, a survey on these smaller sized enterprises located throughout China was conducted in the summer of 2006. Respondents were selected from urban and rural areas, coastal and inland provinces and various industries to provide information on their opinions on how some of their cultural beliefs have changed from 1990 to present. Specific beliefs questioned include: Use of fengshui, Traditional Forbidden Activities, Company Naming Responsibility, Company Name Basis, Use of Numbers, Use of Physiognomy, and Prediction of a Company's Future. The importance of fengshui has risen over in the last sixteen years and certain traditional forbidden activities such as not turning over the fish while eating has remained important as a cultural belief Naming a company is important and the desirability of a good name is based on various factors. Use of numbers, physiognomy, and non-scientific methods for predicting the future success of companies are of lesser use. These aspects of cuhure are reviewed in consideration of the change from a planned economy to a market-based economy.

An early geikiid dicynodont from the Tropidostoma Assemblage Zone (late Permian of South Africa

2017-01-01

Full Text Available Based on specimens previously identified as Tropidostoma, a new taxon of dicynodont (Bulbasaurus phylloxyron gen. et sp. nov. from the Karoo Basin of South Africa is described. Bulbasaurus is a medium-sized dicynodont (maximum dorsal skull length 16.0 cm restricted to the Tropidostoma Assemblage Zone (early Lopingian of the Beaufort Group. Bulbasaurus can be distinguished from Tropidostoma by an array of characters including the presence of a tall, sharp premaxillary ridge, large, rugose, nearly-confluent nasal bosses, a nasofrontal ridge, massive tusks, robust pterygoids, prominently twisted subtemporal bar, and absence of a distinct postfrontal. Inclusion of Bulbasaurus in a phylogenetic analysis of anomodont therapsids recovers it as a member of Geikiidae, a clade of otherwise later Permian dicynodonts such as Aulacephalodon and Pelanomodon. Bulbasaurus exhibits many of the characters typical of adult Aulacephalodon, but at substantially smaller skull size (these characters are absent in comparably-sized Aulacephalodon juveniles, suggesting that the evolution of typical geikiid morphology preceded gigantism in the clade. Bulbasaurus is the earliest known geikiid and the only member of the group known from the Tropidostoma Assemblage Zone; discovery of this taxon shortens a perplexing ghost lineage and indicates that abundant clades from the later Permian of South Africa (e.g., Geikiidae, Dicynodontoidea may have originated as rare components of earlier Karoo assemblage zones.

Sánchez-Medina, Agustín J; Romero-Quintero, Leonardo; Sosa-Cabrera, Silvia

2014-01-01

In the business context, concern for the environment began to develop when pressure from the public administration and environmental awareness groups raised the specific requirements for companies. The Theory of Planned Behavior considers that people's conduct is determined by the intention of carrying out a certain behavior. Thus, the individual's intent is determined by three factors related to the desired outcome of the behavior: the Personal Attitude toward the Results, the Perceived Social Norms, and the Perceived Behavioral Control over the action. Therefore, the objectives of this paper are to clarify the attitudes of the managers of Canarian small and medium-sized companies about taking environmental measures, and try to demonstrate whether there is a relationship between the proposed factors and the intention to take these measures.

2009-02-01

Waste prevention is a principle means of achieving the goals of waste management and a key element for developing sustainable economies. Small and medium sized enterprises (SMEs) contribute substantially to environmental degradation, often not even being aware of their environmental effects. Therefore, several initiatives have been launched in Austria aimed at supporting waste prevention measures on the level of SMEs. To promote the most efficient projects, they have to be evaluated with respect to their contribution to the goals of waste management. It is the aim of this paper to develop a methodology for evaluating waste prevention measures in SMEs based on their goal orientation. At first, conceptual problems of defining and delineating waste prevention activities are briefly discussed. Then an approach to evaluate waste prevention activities with respect to their environmental performance is presented and benchmarks which allow for an efficient use of the available funds are developed. Finally the evaluation method is applied to a number of former projects and the calculated results are analysed with respect to shortcomings and limitations of the model. It is found that the developed methodology can provide a tool for a more objective and comprehensible evaluation of waste prevention measures.

Barriers to energy efficiency improvement. Empirical evidence from small-and-medium-sized enterprises in China

Energy Technology Data Exchange (ETDEWEB)

Kostka, Genia; Moslener, Ulf; Andreas, Jan G.

2012-07-01

This paper analyzes barriers for energy efficiency investments for small-and medium-sized enterprises (SMEs) in China. Based on a survey of 480 SMEs in Zhejiang Province, this study assesses financial, informational, and organizational barriers for energy efficiency investments in the SME sector. The conventional view has been that the lack of appropriate financing mechanisms particularly hinders SMEs to adopt cost-effective energy efficiency measures. As such, closing the financing gap for SMEs is seen as a prerequisite in order to promote energy efficiency in the sector. The econometric estimates of this study, however, suggest that access to information is an important determinant of investment outcomes, while this is less clear with respect to financial and organizational factors. More than 40 percent of enterprises in the sample declared that that they are not aware of energy saving equipments or practices in their respective business area, indicating that there are high transaction costs for SMEs to gather, assess, and apply information about energy saving potentials and relevant technologies. One implication is that the Chinese government may assume an active role in fostering the dissemination of energy-efficiency related information in the SME sector. (orig.)

Conducting Creativity Brainstorming Sessions in Small and Medium-Sized Enterprises Using Computer-Mediated Communication Tools

Science.gov (United States)

Murthy, Uday S.

A variety of Web-based low cost computer-mediated communication (CMC) tools are now available for use by small and medium-sized enterprises (SME). These tools invariably incorporate chat systems that facilitate simultaneous input in synchronous electronic meeting environments, allowing what is referred to as “electronic brainstorming.” Although prior research in information systems (IS) has established that electronic brainstorming can be superior to face-to-face brainstorming, there is a lack of detailed guidance regarding how CMC tools should be optimally configured to foster creativity in SMEs. This paper discusses factors to be considered in using CMC tools for creativity brainstorming and proposes recommendations for optimally configuring CMC tools to enhance creativity in SMEs. The recommendations are based on lessons learned from several recent experimental studies on the use of CMC tools for rich brainstorming tasks that require participants to invoke domain-specific knowledge. Based on a consideration of the advantages and disadvantages of the various configuration options, the recommendations provided can form the basis for selecting a CMC tool for creativity brainstorming or for creating an in-house CMC tool for the purpose.

Work-related stress in small and medium-sized enterprises (SMEs) is an increasing problem. However, knowledge regarding organizational-level interventions in SMEs is limited, and SMEs often lack professional facilitator resources to assist in change processes. An intervention program developed...... for large corporations, the PoWRS (Prevention of Work-Related Stress) program, has been modified to fit the conditions in SMEs, i.e., appointing employees as in-house facilitators. The aim of this paper is to examine the enablers and inhibiting factors of the PoWRS program when applied in four Danish SMEs....... Three out of four of the case companies succeeded in implementing the program. The enablers and inhibiting factors related to three themes: persons and roles, program components, and organizational context. Findings show that the primary enabling factors were the in-house employee facilitators...

SWR 1000: An Advanced, Medium-Sized Boiling Water Reactor, Ready for Deployment

International Nuclear Information System (INIS)

Brettschuh, Werner

2006-01-01

The latest developments in nuclear power generation technology mainly concern large-capacity plants in the 1550 -1600 MW range, or very small plants (100 - 350 MW). The SWR 1000 boiling water reactor (BWR), by contrast, offers all of the advantages of an advanced plant design, with excellent safety performance and competitive power generation costs, in the medium-capacity range (1000 - 1250 MW). The SWR 1000 is particularly suitable for countries whose power systems are not designed for large-capacity generating facilities. The economic efficiency of this medium-sized plant in comparison with large-capacity designs is achieved by deploying very simple passive safety equipment, simplified systems for plant operation, and a very simple plant configuration in which systems engineering is optimized and dependence on electrical and instrumentation and control (I and C) systems is reduced. In addition, systems and components that require protection against natural and external man-made hazards are accommodated in such a way that as few buildings as possible have to be designed to withstand the loads from such events. The fuel assemblies to be deployed in the SWR 1000 core, meanwhile, have been enlarged from a 10 x 10 rod array to a 12 x 12 array. This reduces the total number of fuel assemblies in the core and thus also the number of control rods and control rod drives, as well as in-core neutron flux monitors. The design owes its competitiveness to the fact that investment costs, maintenance costs and fuel cycle costs are all lower. In addition, refueling outages are shorter, thanks to the reduced scope of outage activities. The larger fuel assemblies have been extensively and successfully tested, as have all of the other new components and systems incorporated into the plant design. As in existing plants, the forced coolant circulation method is deployed, ensuring problem-free startup, and enabling plant operators to adjust power rapidly in the high power range (70

Computational electronic structure calculations are routinely undertaken to predict thermodynamic properties of the various species. However, the application of highly accurate wave function theory methods, such as the “gold standard” coupled cluster approach including single, double and partly triple excitations in perturbative fashion, CCSD(T), to large molecules is limited due to high computational cost. In this work, the promising domain based local pair natural orbital coupled cluster approach, DLPNO-CCSD(T), has been tested to reproduce 113 accurate formation enthalpies of medium-size molecules (few dozens heavy atoms) important for bio- and combustion chemistry via the reaction based Feller-Peterson-Dixon approach. As for comparison, 8 density functional theory (B3LYP, B3LYP-D3, PBE0, PBE0-D3, M06, M06-2X, ωB97X-D3, and ωB97M-V) and MP2-based (B2PLYP-D3, PWPB95-D3, B2T-PLYP, B2T-PLYP-D, B2GP-PLYP, DSD-PBEP86-D3, SCS-MP2, and OO-SCS-MP2) methods have been tested. The worst performance has been obtained for the standard hybrid DFT functionals, PBE0 (Mean unsigned error (MUE)/ Mean Signed Error (MSE)=9.1/6.0 kcal/mol) and B3LYP (MUE/MSE=13.5/-13.3 kcal/mol). An influence of an empirical dispersion correction term on these functionals performance is not homogenous: B3LYP performance is improved (B3LYP-D3 (MUE/MSE=6.0/0.8 kcal/mol)) meanwhile PBE0 performance is worse (PBE0-D3 (MUE/MSE=14.1/13.6 kcal/mol)).

Computational electronic structure calculations are routinely undertaken to predict thermodynamic properties of the various species. However, the application of highly accurate wave function theory methods, such as the “gold standard” coupled cluster approach including single, double and partly triple excitations in perturbative fashion, CCSD(T), to large molecules is limited due to high computational cost. In this work, the promising domain based local pair natural orbital coupled cluster approach, DLPNO-CCSD(T), has been tested to reproduce 113 accurate formation enthalpies of medium-size molecules (few dozens heavy atoms) important for bio- and combustion chemistry via the reaction based Feller-Peterson-Dixon approach. As for comparison, 8 density functional theory (B3LYP, B3LYP-D3, PBE0, PBE0-D3, M06, M06-2X, ωB97X-D3, and ωB97M-V) and MP2-based (B2PLYP-D3, PWPB95-D3, B2T-PLYP, B2T-PLYP-D, B2GP-PLYP, DSD-PBEP86-D3, SCS-MP2, and OO-SCS-MP2) methods have been tested. The worst performance has been obtained for the standard hybrid DFT functionals, PBE0 (Mean unsigned error (MUE)/ Mean Signed Error (MSE)=9.1/6.0 kcal/mol) and B3LYP (MUE/MSE=13.5/-13.3 kcal/mol). An influence of an empirical dispersion correction term on these functionals performance is not homogenous: B3LYP performance is improved (B3LYP-D3 (MUE/MSE=6.0/0.8 kcal/mol)) meanwhile PBE0 performance is worse (PBE0-D3 (MUE/MSE=14.1/13.6 kcal/mol)).

Napier University's School of Engineering has been involved in education and research in renewable energy for the past 35 years. With the aim demonstration of the viability of production of solar electricity at a high latitude location such as Edinburgh (56 degree north)the school undertook to commission a medium-sized PV electricity generation project. The installation of 32 rows of BP solar silicon panels covering a total area of 160 square metres ensures generation of 17.6kW peak (AC) power. Figure 1 presents a photograph of the facility under discussion. The project has been part (60%) financed by UK Government's PV electricity demonstration programme through the office of Energy Saving Trust. The University has plans to generate hydrogen from solar electricity that will be stored for noctumal production of electricity using fuel-cell technology, thus completing the complete cycle of generation, storage and reproduction of sustainable energy. The project that is part of Napier University's Merchiton Campus was completed on 6 April 2005 and since that date AC power has been fed into the University grid with the peak power being enough to operate up to 80 of the 500 computers at the University's Jack Kilby Computing Centre. DC power is produced from the BP solar high efficincy (17%) monocrystalline panels, each of which produces 90W of power at 22 Volts. This DC electricity is then fed into a total of four inverters hence converting to a stable AC supply. Two of the larger inverters receive current from 12 rows (4 strings x 3 rows) each, while the smaller inverters take power in from 4 rows (2 strings x 2 rows) each. The PV facility is fully instrumented with both input (incident solar energy) and PV electrical energy output recorded at a frequency of 15 minutes. This article will present the energetic, environmental and monetary life cycle assessment (LCA) of the above facility.(Author)

Highlights: ► Allowances, public financing and external pressures as major external drivers. ► Ambitious decision-makers with great entrepreneurial mind as major internal drivers. ► Effect of firm’s size (even within SMEs) on drivers to industrial energy efficiency. ► Preliminary evidences of the effect of firm’s internal and external complexity. ► Preliminary evidences of the effect of firm’s innovation characteristics. - Abstract: Several studies have investigated the barriers to industrial energy efficiency, but few have focused on the most effective means (drivers) to promote the adoption of energy-efficient technologies and practices. In this respect, Small and Medium-sized Enterprises (SMEs) have been completely overlooked despite interesting consequences for their overall energy consumption and their concurrent low levels of adoption of energy-efficiency measures. Starting from insights garnered from the extant literature on the drivers of industrial energy efficiency, this paper presents an empirical investigation of 71 Italian manufacturing SMEs through a multiple case-study approach. The research highlights the importance of allowances or public financing for energy efficiency interventions, as well as the importance of external pressures such as increases in energy prices and the introduction or increasing of fees on both resources consumed and on emissions of pollutants. Moreover, enterprises look favourably upon energy-efficient technologies which are able to provide long-term benefits, evidence of their willingness to adopt seemingly radical solutions when these are able to improve their long-term competitiveness. Other drivers considered as strategic for increasing energy efficiency are the presence within the company of people with great ambition and entrepreneurial mind and the management sensitivity to the issue. This paper also provides a preliminary analysis of how factors such as firm size, sector, supply chain complexity, and

Full Text Available SMEs sector plays a vital role in modern economies. Therefore, the interest in its functioning among economists is in fact quite natural. This article is a part of a current research on regional factors contributing to the development of enterprises in this category. The first section examines earlier studies in this field conducted globally and in Poland. According to them, many elements enable the SME’s development. It is not surprisingly that the specified set of pro-growth factors does not exists. Next section describes the results of the author’s own studies in the fields. These studies relate to regional factors contributing to the efficiency growth of micro, small and medium-sized enterprises in Poland. Data used in the study was collected from GUS[1] and EUROSTAT and encompassed 16 provinces for the years 2003-2008. The model prepared included 11 independent variables on labor force, social mobility, living standard and R&D policy. The authors would have gladly considered more than 11 explanatory variable, but the inaccessibility of such data made it impossible. In the next step, using GRETL software, equations of regression were defined. On this basis it was concluded that the most important factors contributing to efficiency growth of SMEs are the amount of spending on R&D and the level of wages.

Like China, a large portion of South Africa's primary energy is sourced from coal, and is likely to remain South Africa's major source of energy for the short to medium term. It is imperative to address the environmental dimension as an integral component of coal energy considerations. This issue is discussed through energy efficiency, and South Africa's Low-Smoke Coal Programme as it pertains to the use of coal in households. South Africa is engaged on several other programmes to minimise the impact of coal on the atmospheric environment. Some of those activities have been outlined in this paper. (R.P.)

To assess the change in efficiency and total factor productivity (TFP) of the local public hospitals in Japan after the local public hospital reform launched in late 2007, which was aimed at improving the financial capability and operational efficiency of hospitals. Secondary data were collected from the Ministry of Internal Affairs and Communications on 213 eligible medium-sized hospitals, each operating 100-400 beds from FY2006 to FY2011. The improved slacks-based measure nonoriented data envelopment analysis models (Quasi-Max SBM nonoriented DEA models) were used to estimate dynamic efficiency score and Malmquist Index. The dynamic efficiency measure indicated an efficiency gain in the first several years of the reform and then was followed by a decrease. Malmquist Index analysis showed a significant decline in the TFP between 2006 and 2011. The financial improvement of medium-sized hospitals was not associated with enhancement of efficiency. Hospital efficiency was not significantly different among ownership structure and law-application system groups, but it was significantly affected by hospital location. The results indicate a need for region-tailored health care policies and for a more comprehensive reform to overcome the systemic constraints that might contribute to the decline of the TFP. © Health Research and Educational Trust.

Geographic body size and shape variation in a mainland anolis (Squamata: Dactyloidae) from northwestern South America (Colombia)

Anolis auratus is a widely distributed species, from Costa Rica in Central America, through northern South America, including Colombia, Venezuela, northern Brazil, Surinam and the Guyanas. In Colombia, its widespread distribution across different life zones suggests that these lizards occupy different environments and exhibit different microhabitat use in different geographic areas. On the other hand, some observations suggest that this species prefers open areas, selecting grasslands over brushy areas, and thus, an alternative hypothesis is that microhabitat use is similar among different populations. In Anolis, body variables related to locomotion (body size and shape) defines structural microhabitat use, so two distinct patterns could be expected in this species: Conservative or highly variable body size and shape throughout the species distribution. To test these predictions, we characterized geographic variation in morphometric traits of this species in Colombia. Females and males were similar in body size, but exhibited differences in some variables related to body shape. These characteristics also varied among males and females from different regions, suggesting heterogeneous use of structural microhabitat, between sexes and among populations. As an alternative, phylogenetic divergence among populations could also account for the observed differences. Absence of ecological and phylogenetic data limits our ability to identify the underlying causes of this pattern. However, we provide a general framework to explore hypotheses about evolution of body size and shape in this species.

In the business context, concern for the environment began to develop when pressure from the public administration and environmental awareness groups raised the specific requirements for companies. The Theory of Planned Behavior considers that people's conduct is determined by the intention of carrying out a certain behavior. Thus, the individual's intent is determined by three factors related to the desired outcome of the behavior: the Personal Attitude toward the Results, the Perceived Social Norms, and the Perceived Behavioral Control over the action. Therefore, the objectives of this paper are to clarify the attitudes of the managers of Canarian small and medium-sized companies about taking environmental measures, and try to demonstrate whether there is a relationship between the proposed factors and the intention to take these measures.

We studied coupled granular/continuous (CGC) perpendicular media consisting of a continuous multilayer structure and a granular layer. The addition of Co/Pt multilayers decreased the nucleation field from 200 to -1800 Oe and increased the squareness from 0.9 to 1.0. The moment decay at room temperature was significantly reduced from -4.8% to -0.05% per decade. At elevated temperatures, strong exchange coupling between a granular layer and a continuous layer is needed for thermal stability. The exchange-coupled continuous layer reduces thermal demagnetization as it effectively increases the grain size, tightens the grain distribution, and prevents the reversal of individual grains. Magnetic Force Microscope image showed a larger magnetic cluster size for the CGC structure. Compared to the CoCr 18 Pt 12 medium, the CGC medium had 2.3 dB higher output. However, the noise for the CGC medium increased with the recording density, while the noise for the CoCr 18 Pt 12 medium remained constant from 4 to 15 kfc/mm. Further optimization and noise reduction are still required for future high density recording

Full Text Available The aim of the article was getting to know the factors, determining socio-economic activity of small and mediumsized businesses on border areas in Warmińsko-Mazurskie voivodeship. The study was conducted by telephone interviewing in 2015 amongst randomly selected group of 76 entrepreneurs. The gathered empirical data allowed to determine the areas which need taking action from local authorities to work for socio-economic development of border areas and improve the functionality conditions of the already existing companies. In entrepreneurs’ opinion, an important element in small and medium-sized businesses development is advertisement of the area and introduction of investment incentives. The study shows that endogenous possibilities of entrepreneurship development are limited. The most frequently raised issues were connected with the functioning of companies in their remote location, and also progressing depopulation of the area and low purchasing power of the local community.

New advanced small and medium nuclear power reactors: possible nuclear power plants for Australia

International Nuclear Information System (INIS)

Dussol, R.J.

2003-01-01

In recent years interest has increased in small and medium sized nuclear power reactors for generating electricity and process heat. This interest has been driven by a desire to reduce capital costs, construction times and interest during construction, service remote sites and ease integration into small grids. The IAEA has recommended that the term 'small' be applied to reactors with a net electrical output less than 300 MWe and the term 'medium' to 300-700 MWe. A large amount of experience has been gained over 50 years in the design, construction and operation of small and medium nuclear power reactors. Historically, 100% of commercial reactors were in these categories in 1951-1960, reducing to 21% in 1991-2000. The technologies involved include pressurised water reactors, boiling water reactors, high temperature gas-cooled reactors, liquid metal reactors and molten salt reactors. Details will be provided of two of the most promising new designs, the South African Pebble Bed Modular Reactor (PBMR) of about 110 MWe, and the IRIS (International Reactor Innovative and Secure) reactor of about 335 MWe. Their construction costs are estimated to be about US$l,000/kWe with a generating cost for the PBMR of about US1.6c/kWh. These costs are lower than estimated for the latest designs of large reactors such as the European Pressurised Reactor (EPR) designed for 1,600 MWe for use in Europe in the next decade. It is concluded that a small or medium nuclear power reactor system built in modules to follow an increasing demand could be attractive for generating low cost electricity in many Australian states and reduce problems arising from air pollution and greenhouse gas emissions from burning fossil fuels
