    Ministry of the Environment (MD) wanted an overview of current knowledge of climate-friendly and attractive urban development in medium-sized cities (10 - 50 000 inhabitants). This report presents and discusses knowledge between major cities' situation and challenges of land use and transport development to reduce car traffic and greenhouse gas emissions and on urban development for more attractive cities. A main conclusion is that there are major gaps in knowledge and opportunities for improvement. If those covered will be far better opportunities for planners, local authorities and others may be able to contribute to more climate-friendly and attractive medium-sized cities.The report is part of the project Comprehensive information pack for the status of knowledge from research on urban development. The project has also prepared a report entitled Planning for attractive urban environment. The reports are intended to complement each other and should be seen in context.(eb)

    This paper aims to analyse the evolution experienced by the neighbourhoods that comprise the so-called first periphery. Most of them have been thoroughly studied, has led to recognize theirs values and to be included in the catalogues of heritage protection of their respective cities. However, this research shows that is pending an in-depth analysis in cities of intermediate scale. Its significance lies not only in the fact that they are the most significant operations of architecture of the modern movement in their respective cities, but are especially noteworthy the values derived from its strategic location within the urban structure of these intermediate scale cities. Being near to city centre, they have been constituted as transition pieces between historic sites, new peripheral developments, and even, their nearest territory. As method, this research proposes a comparative analysis of traceability among different study cases, from medium-sized cities of the Andalusian Coast (Spain). In this context, it means recording the evolution that these promotions have been experienced since their first designs until their current situation. It attempts to find the characteristics that have resulted in the urban configuration of this periphery and to recognize the sum of all the cultural, economic, social and technological aspects that conditions the ways of life that today are detected in them. Definitely, the knowledge generated by this research allows extracting architectural and urban values of these examples, which justify its necessary dissemination as part of our legacy.

    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

    2005-01-01

    This research in four medium-sized Chinese cities aims at measuring urban sustainability in China and focuses on three issues. First, the situation in these four cities with regard to urban sustainability is evaluated. Secondly, a number of relations between different aspects of urban sustainability is explored. Finally, it is indicated how urban managers can improve with sustainability indices as tools currently ineffective urban management practices. Although all four cities are moving towards sustainable development, the current situation shows still weak sustainability in three, and even non-sustainability in one city. The social and, in particular, the economic dimensions of urban sustainability make significant positive contributions to overall urban sustainability. However, the decline of natural resources and environmental degradation are influencing it negatively. It is therefore suggested that more priority should be assigned to urban environmental protection and management in China. The fundamental reason for environmental degradation is believed to be inefficient urban management. To implement effective urban management in China, there is an urgent need to redefine the role of local government, reform local organizational structure, enhance local participatory institutional capacity, properly distribute the urban welfare, and thus integrate economic, social and environmental objectives local strategic and action plans

    Urbanization transforms undeveloped landscapes into built environments, causing changes in communities and ecological processes. Flying arthropods play important roles in these processes as pollinators, decomposers, and predators, and can be important in structuring food webs. The goal of this study was to identify associations between urbanization and the composition of communities of flying (and floating) arthropods within gardens and parks in a medium-sized mesic city. We predicted that flying arthropod abundance and diversity would respond strongly to percent impervious surface and distance to city center, measurements of urbanization. Flying arthropods were sampled from 30 gardens and parks along an urbanization gradient in Toledo, Ohio, during July and August 2016, using elevated pan traps. A variety of potential predictor variables were also recorded at each site. We collected a total of 2,369 individuals representing nine orders. We found that flying arthropod community composition was associated with percent impervious surface and canopy cover. Overall flying arthropod abundance was negatively associated with percent impervious surface and positively associated with distance to city center. Hymenoptera (bees, wasps, ants), Lepidoptera (moths, butterflies), and Araneae (spiders) were positively associated with distance to city center. Hemiptera (true bugs), Diptera (flies), and Araneae were negatively associated with percent impervious surface. Both distance to city center and percent impervious surface are metrics of urbanization, and this study shows how these factors influence flying arthropod communities in urban gardens and city parks, including significant reductions in taxa that contain pollinators and predators important to urban agriculture and forestry. A variety of environmental factors also showed significant associations with responses (e.g. canopy cover and soil moisture), suggesting these factors may underlie or modulate the urbanization

    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 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.

    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.

    Background Motorcycle vehicles are frequent in China, especially in the small and medium sized cities. Road traffic collisions involving motorcycles often result in severe injuries. We aimed to identify risk factors for severe injuries in inpatients sustaining motorcycle collisions. Methods Patients with road traffic injuries involving motorcycles who presented to the neurosurgery and orthopedic departments of three major comprehensive hospitals in Shantou city were reviewed from October 2012 to June 2013. Data from 349 patients was investigated. Crash and injury characteristics were documented by interviewing patients, their family members, and their doctors. Binary logistic regression was used to determine risk factors for severe injuries. Results There were 253 males (72.49%) and 96 females (27.51%), with a male to female ratio of 2.64:1. The mean age was 38.21±17.32 years. One-hundred and fifty patients were in the severe injury group with a mean injury severity score (ISS) of 15.34±9.13. The simple and multiple logistic model showed that males, lack of safeguards, morning and night hours, non-urban areas, collision of a motorcycle with a cycle, ambulance transportation to hospital, admission to a neurosurgery department, lack of traffic control, unobstructed traffic, and poor visibility were all the risk factors. Conclusions This research highlights some problems: less helmet wearing in motorcyclists and cyclists, rural injuries being more serious than urban ones, and head injuries being the main diagnosis in severe injuries. The result of this research is predictable. If the safety equipment is required to be used, such as helmets, and the traffic environment is improved, such as traffic flow, medical resources to injuries and deaths is seasonable, then traffic safety will be improved and accidents will be reduced.

    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.

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.

    During 1965-79, urban growth rates accelerated and continued after Zimbabwe's independence in 1980. For 1960-80, the estimated urban growth rate was 5.6% as compared with the natural growth rate of 3.5% and urban growth rate of 5.0% to 8.1% for the period 1982-92. Gweru, Zimbabwe, had a population of 110,000 in 1990, and as the provincial capital it is an important destination for rural and interurban migrants. Between 1982 and 1990 there was a 4.9% growth rate, resulting in the municipal waiting list for housing to exceed 14,000 in mid-1990. In a large study on migration and rental shelter, 188 tenants were interviewed in high, low-medium density, and periurban areas of the city with the intent of tracing respondents and the nature of migration streams. Regarding origins and connections, only one-fifth of the migrants were born in Gweru, more than half were born in rural areas, and the rest in other urban areas. More than 90% still had rural homes. Two-thirds made rural home visits six times or less a year and one-fourth visited seven times a year to once a month. 40% of the migrants to Gweru originated in larger cities, 24% in smaller urban areas, and 36% in rural areas. 58% moved to high density areas, 34% to low-medium, and 8% to peri-urban areas. The dominant motive was the search for employment and direct transfers, thus economic factors dominated over social factors. Three groups were distinguished according to length of stay: 1) 5 years or less who lived mainly in high and low-medium density housing; 2) 6-15 years; and 3) more than 15 years who lived in low density and high density areas. Regarding the previous two migrations, two-thirds stayed at the previous place for 5 years of less. The reasons for migration were overcrowding, family, and employment. Within Gweru high mobility was typical: one-third initiated one step, 43% initiated two steps, and 27% initiated three steps. Lodgers were the most mobile since one-third were moving three times.

    Taipei, a subtropical modern medium city, is essentially featured with high population density, scarce land, and large traffic flow. Moreover, there are abundant green energy resources reserved in Taipei. If they were fully developed, there would be 13,040 GWh electricity generated per year, resulting in a total of 9.37 million tons of carbon dioxide emissions abatement. The development of the green energy industry in this city not only can bring significant energy-saving and carbon-reducing benefits, but also may create huge derivative business opportunities. For example, the total output values of the solar PV and electric vehicles industries would be as high as 700 billion yuan. In this study, through Strengths, Weaknesses, Opportunities, and Threats (SWOT) analysis, we concluded that the top priorities for Taipei for the development of green energy industries are building energy conservation and electrified transportation, specifically, the following four items: electric vehicles, Light-Emitting Diode (LED) lighting, inverter air conditioning, and Energy Service Company (ESCO). Meanwhile, Taipei is a domestic and international key of politics, transportation, technology, commerce, and finance. Taipei is very likely to become an internationalized green energy industrial hub, achieving the “3E” goals of economic prosperousness, environmental protection, and energy security. -- Highlights: •Building energy conservation and electrified transportation are top priorities. •SWOT analysis applied to systematically conclude four green energy industrial items for Taipei. •Specifically, electric vehicles, LED lighting, inverter air conditioning, and ESCO. •13,040 GWh electricity would be generated per year from Taipei's rich renewables. •The derivative business opportunities would exceed 700 billion yuan

    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.

    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.

    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.

    Urban centers have a huge demand for electricity and the growing problem of the solid waste management generated by their population, a relevant social and administrative problem. The correct disposal of the municipal solid waste (MSW) generated in cities is one of the most complex engineering problems that involves logistics, safety, environmental and energetic aspects for its adequate management. Due to a national policy of solid wastes recently promulgated, Brazilian cities are evaluating the technical and economic feasibility of incinerating the non-recyclable waste. São José dos Campos, a São Paulo State industrialized city, is considering the composting of organic waste for biogas production and mass incineration of non-recyclable waste. This paper presents a waste-to-energy system based on the integration of gas turbines to a MSW incinerator for producing thermal and electric energy as an alternative solution for the solid waste disposal in São José dos Campos, SP. A technical and economic feasibility study for the hybrid combined cycle plant is presented and revealed to be attractive when carbon credit and waste tax are included in the project income. - Highlights: ► We model a hybrid waste-to-energy cogeneration system for the disposal of MSW. ► Reference model for MSW treatment consists of biogas burning and composting. ► Hybrid cogeneration solution is superior to the biogas burning reference model. ► Carbon credit and waste tax increase the attractiveness of the proposed solution

    Full Text Available OBJECTIVE: characterize the hospital morbidity of adults living in the city of Maringá, PR, Brazil, between 2000 and 2011, focusing on the differential between men and women. METHOD: this descriptive study was developed based on data from the Hospital Information System of the Unified Health System in order to investigate the association between groups of hospitalization causes and the average length of hospitalization per gender, in three-year periods. RESULTS: the main groups of hospitalization causes for men were: mental disorders, lesions and circulatory diseases; and, among women: tumors, circulatory and genitourinary diseases. Mental disorders and lesions, tumors, circulatory and genitourinary diseases were significantly associated with the female and male genders across the study period. Although not significant, the mean length of hospitalization dropped across the four three-year periods, and only showed a significant difference between men and women in the second triennium. CONCLUSION: differences in the hospital morbidity profile between men and women underline the need for specific health and nursing actions, especially in primary health care, with a view to reducing hospitalizations due to the main groups of causes in the city.

    Full Text Available Changes in violent crime rates implies a need for strategies to protect the population. Public safety policies should be focused on preventive security, which has the potential to reduce crime rates. The allocation of the police observation posts contributes to an increase in safety. However, given limited resources, the number of observation units has reduced in most Brazilian cities. Therefore, efficient allocation of these resources is necessary to ensure rational use of security agents. Several aspects influence decisions related to where to install these units, complicating this process. The multiple criteria approach is appropriate in this type of decision-making process, because it allows the decision maker to generate and consolidate knowledge. The results indicate that the most suitable neighborhoods are those with higher rates of violence and greater social gaps. This work presents some benefits to the area of public security, since it formalizes tacit knowledge into explicit knowledge. The information contained in this study may be made available to other public administrators who need to make this kind of decision.

    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.

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

    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.

    Full Text Available When employed in a focused manner, corporate performance evaluation has proven to be instrumental for entrepreneurs as an important tool that contributes with performance improvements at their organizations. The descriptive study herein, prepared as of a questionnaire comprising 46 queries, poses to analyse the performance of micro and small companies (MSEs by employing the multicriteria methodology for constructive decision aiding (MCDA-C. As of respondent replies, MCDA-C descriptors were formed, shaping six prime groups so as to identify relevant factors that drive or hinder MSE success. The questionnaire was applied to managers in charge administering 25 small and medium-sized companies of Lages, a city within the Brazilian state of Santa Catarina. Study findings provide evidence as to the fact that (i 24% of surveyed companies, tend to go bankrupt; (ii managerial functions at the MSEs are the prime source of influence on negative outcomes; (iii from a financial control standpoint, surveyed companies fall far shorter than the minimum level deemed necessary to qualify as satisfactory; (iv those that present the best results, operate both within the domestic and international markets; (v the study placed under the spotlight the group “Evolution Stage”, evidencing the trend of ever increasing MSE expansion. This study revealed that corporate failure contributing factors are intensely interconnected and largely depend on the entrepreneur´s own performance, the prime contribution of findings residing in demonstrating that MCDA-C can be employed to analyse the performance of micro and small businesses.

    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.

    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

    Understanding emissions from cities is increasingly important as a growing fraction of the world's population moves to cities. Here we use a novel technology, dual frequency comb spectroscopy, to measure city emissions using a long outdoor open path. We simultaneously measured CO2, CH4, and H2O over the city of Boulder, Colorado and over a clean-air reference path for two months in the fall of 2016. Because of the spatial coverage of our measurements, the layout of the city and power plant locations, and the predominant wind direction, our measurements primarily pick up vehicle emissions. We choose two days with consistent CO2 enhancements over the city relative to the reference path and use a simple 0-D box model to calculate city emissions for these days. We scale these up to annual emissions and compare our measurements with the City of Boulder bottom-up vehicle emissions inventory based on total vehicle miles traveled, fuel efficiency, and vehicle type distribution. We find good agreement (within about a factor of two) between our top-down measurements and the city's bottom-up inventory value.

    Full Text Available Tardigrade diversity was studied in a medium-sized city in the Neotropical Region: Santa Rosa (La Pampa, Argentina. Samples were collected between February 1999 and January 2000 from lichens and mosses growing on sidewalk trees of the urban and periurban area. Five species of tardigrades were found, i.e., Echiniscus rufoviridis du Bois-Reymond Marcus, 1944, Macrobiotus areolatus Murray, 1907, Ramazzottius oberhaeuseri (Doyère, 1840, Milnesium cf. tardigradum and a non-described species of Macrobiotus. Only one species, M. cf. tardigradum, was found in areas with high levels of vehicle traffic. Results are compared with those from cities in the Nearctic and Palearctic regions. Measurements and pt index values (percentage ratios between the length of the structure considered and the buccal tube length are provided for M. areolatus, R. oberhaeuseri and M. cf. tardigradum. Amongst the characters considered, the pt index for the stylet support insertion shows the least intraspecific variation. This character is also independent from body length and buccal-tube length.

    The authors analyze soil relations with other elements of the city ecosystem (the position in the landscape, soil-forming rocks and lithology, vegetation and its state) to develop the legend and map of soils in the City of Birobidzhan (scale 1:25 000). The focus of study is the morphological structure of urban soils with different degree of disturbance of these relations under the impact of technical effects, economic and recreational activities of the city population. The soil cover structure is composed of four large ecological groups of soils: natural untransformed, natural with a disturbed surface, anthropogenic soils and technogenic surface formations. Using cartometry of the mapped soil contours the authors created the scheme of soil-ecological city zoning, which in a general way depicts the state of soil ecological functions in the city as well as identified zones of soils with preserved, partially and fully distured ecological functions and zones of local geochemical anomalies at the initial formation stage (environmental risk zones).

    According to the major pollution sources of urban water environment, 10 indexes such as industrial sewage quantity were closen to establish evaluation indexes system about the types and influencing factors of the typical and medium-small-sized cities in the southern China. Case studies of 16 typical and medium-small-sized cities were taken in Jiangsu, Zhejiang, Hubei and Anhui provinces. Combined with SPSS 11.0 cluster analysis results, city types were divided in reference to the values of water resources comprehensive pollution indexes and economical development indexes. The driving forces about city water environment pollution were studied by principal component analysis method. The result indicates that the 16 cities belong to two categories and four sub-categories, which are rich economy as well as light pollution of water environment and poor economy as well as heavy pollution of water environment. The influencing factors of water environment pollution are in sequence of industrial water pollution, agricultural no-point source pollution and urban domestic water pollution. The main factors of water environment pollution influenced I category cities, II as well as IV category cities and III category cities are industrial water pollution, urban domestic pollution and agricultural no-point source pollution respectively.

    The aim of this study was to clarify the actual state of retired workers' lifestyles and quality of life (QOL) in a medium-sized city of Northeastern China and to assess the relationship between these according to differences between gender groups. The Chinese version of the Health Promotion Lifestyle Profile II (HPLP-II), the World Health Organization Quality of Life-BREF (WHOQOL-BREF), and demographic variables were used to measure 343 (aged 50-79 years) retired workers' lifestyles and QOL. The results were analyzed using the t test, one-way analysis of variance, correlation analysis, and multiple linear regression analysis. Among the six lifestyle subscales of HPLP-II, the highest mean score was for Interpersonal Relations (IR) and the lowest was for Health Responsibility (HR), which has not been reported previously. The youngest group (50-60 years) had higher scores for lifestyles and QOL than the other age groups. When the results were analyzed based on financial situation, the lowest income group (below ¥2000) had the poorest scores. Analysis according to gender group revealed different tendencies for the scores of lifestyle and QOL, as well as in the multiple regression analysis between variables. Our results suggest that an effective approach to maintain a desirable lifestyle and QOL for retired workers at the regional level would be to introduce daily activities to improve HR and to maintain and enhance social support for the low-income populations. Further research is needed to understand the complex causal pathways between regional health and welfare factors, health behavior, and QOL.

    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

    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.

    Full Text Available The spatial distribution of heat stress in a Central European city and its surroundings was examined. We evaluated the length of time for which the threshold values of Humidex and air temperatures were exceeded at individual stations. The longest interval of temperature discomfort was detected at the border of open mid-rise development and open spaces. The shortest intervals were found in compact mid-rise development and near a forest. There are spatial differences between locations with long periods of high temperatures and locations with long intervals of high Humidex values. However, when the heat stress is being assessed in relation to the mortality rate, Humidex does not show better results than the air temperature.

    Identify the possibility that alcohol consumption represents an incremental factor in healthcare costs of patients involved in traffic accidents. Data of people admitted into three major health institutions from an intermediate city in Colombia was collected. Socio-demographic characteristics, health care costs and alcohol consumption levels by breath alcohol concentration (BrAC) methodology were identified. Generalized linear models were applied to investigate whether alcohol consumption acts as an incremental factor for healthcare costs. The average cost of healthcare was 878 USD. In general, there are differences between health care costs for patients with positive blood alcohol level compared with those who had negative levels. Univariate analysis shows that the average cost of care can be 2.26 times higher (95% CI: 1.20-4.23), and after controlling for patient characteristics, alcohol consumption represents an incremental factor of almost 1.66 times (95% CI: 1.05-2.62). Alcohol is identified as a possible factor associated with the increased use of direct health care resources. The estimates show the need to implement and enhance prevention programs against alcohol consumption among citizens, in order to mitigate the impact that traffic accidents have on their health status. The law enforcement to help reduce driving under the influence of alcoholic beverages could help to diminish the economic and social impacts of this problem. Copyright © 2014 Elsevier Ltd.

    We apply five distributions-lognormal, double-Pareto lognormal, lognormal-upper tail Pareto, Pareto tails-lognormal, and Pareto tails-lognormal with differentiability restrictions-to estimate the size distribution of all Indian cities. Since India contains numerous small cities, it is important to explicitly model the lower-tail behavior for studying the distribution of all Indian cities. Our results rigorously confirm, using both graphical and formal statistical tests, that among these five distributions, Pareto tails-lognormal is a better suited parametrization of the Indian city size data, verifying that the Indian city size distribution exhibits a strong reverse Pareto in the lower tail, lognormal in the mid-range body, and Pareto in the upper tail.

  9. Perspective on small and medium size reactors

    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

    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.

    Full Text Available The article discusses the spatial patterns of socio-economic development of small and medium-sized cities in the Volgograd region. We know that small and medium-sized cities as spatial socio-economic systems are not only the support frame of settlement, but the main “engine” of innovative impulses for the surrounding periphery. The scientific novelty of the study consists in the effort to implement a spatial approach to the assessment of the economic security of small and medium-sized cities (SCR. The content of the economic security of cities is determined by two system characteristics of the socio-economic system: economic activity (EA and quality of life (QL of the urban population, or SCR = F (EA; QL. For finding spatial patterns in GIS, great interest is in investigating the environment of each city by calculating the local statistical characteristics of geo-variability which allow assessing trends of spatial variation of the six components of security (human security, technosphere safety, environmental safety, etc., local variations in emissions and their values indicators Ki. The successful solution of these problems is possible with the use of tools of exploratory spatial data analysis (ESDA in ARCGIS, and in particular, the Voronoy maps. The spatial approach has allowed to perform an integrated assessment of the economic security and to evaluate safety risks in small and medium-sized cities of the Volgograd region with the security system of indicators.

  13. From medium-sized to megawatt turbines...

    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 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

    2013-09-01

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

    The applicability of medium-size technique was tested in angiographic examinations of thoracic and abdominal organs. By means of full-size image intensifiers it is possible to carry out organ angiography, and by means of a pace control mechanism for the patient transport, the angiography of the extremities can be realized. Examples are given illustrate the informational value in cases where the arial and venous vascular systems of organs and extremities are concerned. The particular advantages for functional analyses of organ circulatory systems in cases of angiography are described. Two factors of importance are pointed out: the reduction of the exposure to irradiation for the patient on the one hand, and the increasing film prices on the other hand. The authors demand to overcome the psychological problems arising in the medical working groups where the medium-size technique shall be introduced into routine diagnostics. (orig./APR) [de

  4. City Size, Housing Price and Resident Income Gap

    2014-01-01

    Taking the urban population size and urban housing price as the proxy variable of city size,this paper conducts an empirical analysis with the data of CHIPS 2002 and 2008.It is found that the rising of city size and housing prices has important promotion effects on income inequality of city residents.The main reason is that the wage of migrant workers is separated from the housing price of the cities in which they reside;while their wage level can balance the wage level of the ordinary workers of city residents,making it separate from the urban housing price.But the wage of high quality worker of city residents is closely connected with the housing price.The combined action of the multy sizes in China's urban labor market leads to such a result that the greater the size of cities,the higher the urban housing prices,and the larger the income gap between urban residents.This means that in the construction of the new urbanization,to limit the over-expansion of such mega-cities as Beijing,Shanghai and so on and to develop the middle and small cities is an effective way to narrow the income gap between urban residents in China.

  5. Small and medium-sized nuclear power plants

    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.

    1987-01-01

    Several IAEA Member States have shown their interest in reactor design, having a smaller power rating (100-500 MW(e) range) than those generally available on the international market. These small and medium sized power reactors are of interest either for domestic applications or for export into countries with less developed infrastructure. There are different developments undertaken for these power reactors to be ready for offering in the nineties and beyond. The paper gives an overview about the status and different trends in IAEA Member States in the development of small and medium sized reactors for the 90's and provides an outlook for very new reactor designs as a long term option for nuclear power.

    This report contains selected indicators and statistics that describe the urban environmental status and development of 31 medium-sized urban settlements in Norway. The selected indicators are mainly taken from the report 'Framtidens byer' or 'Cities of the Future' (Haagensen T. 2011). This group of cities consists of the 9 largest city region, with 13 belonging municipalities in Norway. The program to the 'Cities of the Future' started in 2008, and is based on an agreement between these cities, the private sector and the state, led by the Ministry of the Environment. The 13 cities are Oslo, Baerum, Drammen, Sarpsborg, Fredrikstad, Porsgrunn, Skien, Kristiansand, Sandnes, Stavanger, Bergen, Trondheim and Tromsoe. The medium-sized urban settlements had around 636 000 inhabitants (as of 1 January 2011), equivalent to about 13 per cent of the population of Norway. From 2009-2011, the population growth within these urban settlements was over 70 000. Some of the greatest challenges to reconciling urban development with environmental considerations are therefore found here. The white paper no. 26 (2006-2007) The governments environmental policy and the state of the environment in Norway has also added to the importance of the urban environment with a comprehensive description of the land use and transport policy. Good land use management contains indicators related to the density of land use and construction activities within urban settlements. The urban area per inhabitant decreased in both the medium-sized urban settlements and the 'Cities of the Future' in Norway from 2000 to 2011, which means that a larger share of new buildings were built in already established urban settlements in this period. During the same period, the density in the 'Cities of the Future' decreased. Too high density of built-up areas may be at the expense of access to playgrounds, recreational areas or touring grounds. Indicators of the population's access to these areas show that there is

    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)

    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)

    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.

    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.

    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.

    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

    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

    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 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.

  14. Global patterns of city size distributions and their fundamental drivers.

    Full Text Available Urban areas and their voracious appetites are increasingly dominating the flows of energy and materials around the globe. Understanding the size distribution and dynamics of urban areas is vital if we are to manage their growth and mitigate their negative impacts on global ecosystems. For over 50 years, city size distributions have been assumed to universally follow a power function, and many theories have been put forth to explain what has become known as Zipf's law (the instance where the exponent of the power function equals unity. Most previous studies, however, only include the largest cities that comprise the tail of the distribution. Here we show that national, regional and continental city size distributions, whether based on census data or inferred from cluster areas of remotely-sensed nighttime lights, are in fact lognormally distributed through the majority of cities and only approach power functions for the largest cities in the distribution tails. To explore generating processes, we use a simple model incorporating only two basic human dynamics, migration and reproduction, that nonetheless generates distributions very similar to those found empirically. Our results suggest that macroscopic patterns of human settlements may be far more constrained by fundamental ecological principles than more fine-scale socioeconomic factors.

    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)

    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

    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.

    The size of cities is known to play a fundamental role in social and economic life. Yet, its relation to the structure of the underlying network of human interactions has not been investigated empirically in detail. In this paper, we map society-wide communication networks to the urban areas of two European countries. We show that both the total number of contacts and the total communication activity grow superlinearly with city population size, according to well-defined scaling relations and resulting from a multiplicative increase that affects most citizens. Perhaps surprisingly, however, the probability that an individual's contacts are also connected with each other remains largely unaffected. These empirical results predict a systematic and scale-invariant acceleration of interaction-based spreading phenomena as cities get bigger, which is numerically confirmed by applying epidemiological models to the studied networks. Our findings should provide a microscopic basis towards understanding the superlinear increase of different socioeconomic quantities with city size, that applies to almost all urban systems and includes, for instance, the creation of new inventions or the prevalence of certain contagious diseases. © 2014 The Author(s) Published by the Royal Society.

    Satrec Initiative and ATSB have been developing a medium-sized aperture camera (MAC) for an earth observation payload on a small satellite. Developed as a push-broom type high-resolution camera, the camera has one panchromatic and four multispectral channels. The panchromatic channel has 2.5m, and multispectral channels have 5m of ground sampling distances at a nominal altitude of 685km. The 300mm-aperture Cassegrain telescope contains two aspheric mirrors and two spherical correction lenses. With a philosophy of building a simple and cost-effective camera, the mirrors incorporate no light-weighting, and the linear CCDs are mounted on a single PCB with no beam splitters. MAC is the main payload of RazakSAT to be launched in 2005. RazakSAT is a 180kg satellite including MAC, designed to provide high-resolution imagery of 20km swath width on a near equatorial orbit (NEqO). The mission objective is to demonstrate the capability of a high-resolution remote sensing satellite system on a near equatorial orbit. This paper describes the overview of the MAC and RarakSAT programmes, and presents the current development status of MAC focusing on key optical aspects of Qualification Model.

    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.

    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 importance of connecting urbanization phenomena and vulnerability assessments, this paper aims to explore vulnerability assessment in three different city sizes in the northern coast of Central Java province of Indonesia. It compares the vulnerability levels of the three cities based on their sizes (that is, levels of urbanization. It uses the most current secondary data from the lowest administrative levels, called as kelurahan (urban village, for its assessment. There are two indexes used to indicate their vulnerability levels, namely exposure and sensitivity index (ESI and adaptive capacity index (ACI. By combining the ESI and ACI, the study found that the kelurahans in Tegal (the medium sized city have similar vulnerability levels. The kelurahans in Semarang (as the big city have more combination of vulnerability levels—indicating that the city has various sensitivity, exposure, as well as adaptive capacity among its kelurahans. In Lasem (the small sized city, due to limitations imposed by adaptation—mostly because of lack of public services and high dependency on primary economic sectors—all of its kelurahans were found to be vulnerable. The study therefore concluded that the bigger a city is, the more the different areas of that city will have varying levels of vulnerability, leading to a high propensity of vulnerability among its inhabitants. On the other hand, the smaller a city is, the less capacity it will have in reducing its emerging vulnerability challenges.

    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.

    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

    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

    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.

Realizou-se um inquérito com 2.539 indivíduos de idade acima de 15 anos em 952 domicílios. As principais variáveis analisadas foram a necessidade de saúde bucal percebida, a procura pelo serviço, a barreira de acesso organizacional e o tipo de serviço e o procedimento utilizado. A utilização de serviços públicos odontológicos especializados foi de 11,7% e básicos de 26%. No município com maior utilização de serviços públicos odontológicos, foi menor o uso de serviços privados. A principal barreira de acesso situou-se na AP (Atenção Primária, entre 5,0% e 15,2%. Observou-se pouca interface da atenção secundária com a AP já que apenas 16,6% dos usuários retornaram a esse nível de atenção. Pode-se concluir que a principal barreira de acesso, em municípios com realidades organizacionais e geográficas específicas parece se situar na AP. Ações preventivas individuais foram pouco relatadas. Recomenda-se a redução de barreiras de acesso na AP, bem como a instituição de um protocolo que estimule a longitudinalidade do cuidado nesse nível.This cross-sectional study sought to describe the main characteristics of access and utilization of primary and specialized public dental services in two medium-sized cities in Bahia with 100% coverage of the Family Health Program.

    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.

    Understanding how urban form is related to air pollution is important to urban planning and sustainability, but the urban form-air pollution relationship is currently muddled by inconsistent findings. In this study, we investigated how the compositional and configurational attributes of urban form were related to different air pollution measures (PM 2.5 , API, and exceedance) in 83 Chinese cities, with explicit consideration of city size and seasonality. Ten landscape metrics were selected to quantify urban form attributes, and Spearman's correlation was used to quantify the urban form-air pollution relationship. Our results show that the urban form and air pollution relationship was dominated by city size and moderated by seasonality. Specifically, urban air pollution levels increased consistently and substantially from small to medium, large, and megacities. The urban form-air pollution relationship depended greatly on seasonality and monsoons. That is, the relationship was more pronounced in spring and summer than fall and winter, as well as in cities affected by monsoons. Urban air pollution was correlated more strongly with landscape composition metrics than landscape configuration metrics which seemed to affect only PM 2.5 concentrations. Our study suggests that, to understand how air pollution levels are related to urban form, city size and seasonality must be explicitly considered (or controlled). Also, in order to mitigate urban air pollution problems, regional urban planning is needed to curb the spatial extent of built-up areas, reduce the degree of urban fragmentation, and increase urban compactness and contiguity, especially for large and megacities.

    2014-06-01

    We characterize the statistical law according to which Italian primary school-size distributes. We find that the school-size can be approximated by a log-normal distribution, with a fat lower tail that collects a large number of very small schools. The upper tail of the school-size distribution decreases exponentially and the growth rates are distributed with a Laplace PDF. These distributions are similar to those observed for firms and are consistent with a Bose-Einstein preferential attachment process. The body of the distribution features a bimodal shape suggesting some source of heterogeneity in the school organization that we uncover by an in-depth analysis of the relation between schools-size and city-size. We propose a novel cluster methodology and a new spatial interaction approach among schools which outline the variety of policies implemented in Italy. Different regional policies are also discussed shedding lights on the relation between policy and geographical features.

    Full Text Available Involvement and development of the private sector in boosting the economy nationwide is a main objective of the current program of the government, which means that a good cooperation between small and medium companies, private companies and multinationals and public environment including both public institutions and policies implemented and developed by them, becomes more than necessary. The paper summarizes the findings of a quantitative research based on a self-applied questionnaire which was aimed at Romanian small and medium-sized enterprises and also of a qualitative research that gives an overview of the process of elaborating and implementing a public policy. The involvement of small and medium-sized enterprises in the process of designing and implementing a public policy can become indispensable but it is well know that there is, in fact, a lack of initiative at this level, from both parties. One of the main research questions of this paper is to find out how much do representatives of small and medium-sized enterprises get involved in the process of elaborating a public policy and how much do these actions and measures impact the organizational policies of the companies themselves. A good cooperation between the business environment and the public institutions and a strong correlation of their joint efforts, should become a common practice between both parties, being crucial that this form of cooperation to be initiated from the very beginning. The contribution of this paper is a practical one, given the fact that the paper itself entails the direct responses of small and medium-sized enterprises on the current and future public policies that directly targets them, providing as well an analysis on the effects of public policies on small and medium-sized enterprises. Thus being said, the paper can also be a guide for both small and medium-sized enterprises in providing examples and measures of involvement and favorable public policies

    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.

    Since the second half of the 20th century, urban environment has experienced significant transformation. Splash of interactivity, bottom-up initiations with development of creative sector of city economy and participatory planning, irretrievably changed the attitude to the urban medium. One of the most intensively growing field - creative industry - provided cities with numerous cultural clusters, which boosted urban economic development and social cohesion. Supported in many cases by gentrification and revitalization, these processes brought renovation of brownfield and more comprehensive approaches to urban design. Understanding of the economic benefits made city managers start an active promotion of creative clusters and their intensive integration into urban life, involving the main museums and cultural institutions. Thus, a new type of cultural clusters - Museum Quarter - appeared. Holding the position of cultural flagman in the historical heart of the city, Museum Quarters (MQs) pretend to take on an important role both in urban planning structure and in social life. Furthermore, such role usually has strong influence on the surrounding districts, in a positive or negative way. Although basic principles are still applied for all types of cultural districts, the phenomena of “Museum Quarters” due to the complexity of planning, operating and maintenance issues, stepped far above basic cultural clusters, requiring substantially new attitude to the planning of such urban entities. Five clusters were chosen for this study: MQs in Vienna, Berlin, Amsterdam, Copenhagen and the currently developing project in Budapest. The main purpose of this paper is to elaborate the principles for the practical implementation of Museum Quarters by the definition and classification of their specific urban planning aspects. The complexity of target object - Museum Quarter - and its multi-level relationships with the whole city, require from the research interdisciplinary

    2018-02-01

    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.

    Full Text Available Background: Logistics outsourcing has been accepted as a strategy through which small and medium-sized enterprises (SMEs can access the logistics capabilities they lack internally at a lower cost. However, the actual effect of logistics outsourcing on firm performance, especially among the SMEs in Nairobi, remains unknown.   Aim: The study aimed to investigate the relationship between logistics outsourcing and firm performance of manufacturing SMEs in Nairobi.   Setting: The study sampled manufacturing SMEs in Nairobi City County.   Method: In this study, a convergent parallel mixed methods design was applied. Survey data were collected from 163 manufacturing SMEs. The data were analysed using structural equation modelling to test the relationship between logistics outsourcing and firm performance. Additionally, in-depth interviews were conducted in five manufacturing SMEs. Thematic analysis was used to analyse interview data to provide more insight in the quantitative data.   Results: The anticipated direct link between logistics outsourcing and performance of manufacturing SMEs was not statistically significant. However, the study revealed a statistically significant indirect positive effect of logistics outsourcing on the performance of manufacturing SMEs through logistics outsourcing performance as a mediator variable. This article further highlights reasons and the process of logistics outsourcing and deduces a logistics outsourcing model for manufacturing SMEs to help improve their firm’s performance.   Conclusion: The established relationship and deduced logistics outsourcing model is likely to guide SME managers as to how to manage logistics outsourcing to improve performance. The finding that logistics outsourcing has a positive indirect effect on the performance of manufacturing SMEs through logistics outsourcing performance makes a significant contribution to theory.

    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.

    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

    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.

    Kida, Yoshihiro

    Medium-and small-sized companies have held up Japanese technologies which situated top level in the world as far. However, for the technologies of medium-and small-sized companies to keep the top-level in the 21 centuries, researchers and engineers are demand to have high technologies. Those engineers are hoped for to have not only “knowledge”, but also “creativity, feeling and experience”. Therefore, in order to create such professional engineers, educational institute must have a function by which a practical training and education can be conducted.

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

    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.

  9. 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).

  10. Regulation of Small and Medium-Sized Business Development in Russia: Problems and Solutions

    Directory of Open Access Journals (Sweden)

    2015-12-01

    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.

  13. Energetic Communities: Planning support for sustainable energy transition in small- and medium-sized communities

    Directory of Open Access Journals (Sweden)

    Full Text Available The necessity for transition in the energy sector is beyond dispute and high on the political agendas. Climate change, the depletion of fossil fuels and the vulnerability of economies to resource speculation and unreliable political systems in the producing countries lay path for a broad implementation of smart alternative solutions. This means the integration of more sustainable renewable energy sources in the existing supply structures or the displacement of existing systems by new ones. Cities and communities are central players in the energy transition process. Energy demand is determined by the built environment. Renewable energy production needs space. The conflicts between different interest groups often break out in the context of local implementation measures that affect urban planning and the appearance of landscapes. Small- and medium-sized communities might prove to be game-changers in the overall energy transition because many problems have to be solved within their ambit. Urban planning is dealing with the numerous processes of urban change. Energy is a fairly new task to be addressed and many stakeholders lack experience and criteria for strategic decision making. After a period of fierce determination to turn the wheel against climate change, it seems that there is a growing resignation among politicians, planners and the public because some things have not turned out the way we’d expected and the hope for quick solutions fades. Rebound-effects seem to eat up the savings to a good extent, and alternative ideas of how sustainable energy systems may be put into place have not yet been persuasive in many cases. Energy systems have proved to be complex. They are still perceived to be important but in practice there is a growing uneasiness about the right steps to take. The overarching research question of this thesis is: What do decision makers in smalland medium-sized communities need to become more successful in implementing

  14. Zipf's law and city size distribution: A survey of the literature and future research agenda

    Science.gov (United States)

    Arshad, Sidra; Hu, Shougeng; Ashraf, Badar Nadeem

    2018-02-01

    This study provides a systematic review of the existing literature on Zipf's law for city size distribution. Existing empirical evidence suggests that Zipf's law is not always observable even for the upper-tail cities of a territory. However, the controversy with empirical findings arises due to sample selection biases, methodological weaknesses and data limitations. The hypothesis of Zipf's law is more likely to be rejected for the entire city size distribution and, in such case, alternative distributions have been suggested. On the contrary, the hypothesis is more likely to be accepted if better empirical methods are employed and cities are properly defined. The debate is still far from to be conclusive. In addition, we identify four emerging areas in Zipf's law and city size distribution research including the size distribution of lower-tail cities, the size distribution of cities in sub-national regions, the alternative forms of Zipf's law, and the relationship between Zipf's law and the coherence property of the urban system.

    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.

  16. The role of city size and urban form in the surface urban heat island.

    2017-07-06

    Urban climate is determined by a variety of factors, whose knowledge can help to attenuate heat stress in the context of ongoing urbanization and climate change. We study the influence of city size and urban form on the Urban Heat Island (UHI) phenomenon in Europe and find a complex interplay between UHI intensity and city size, fractality, and anisometry. Due to correlations among these urban factors, interactions in the multi-linear regression need to be taken into account. We find that among the largest 5,000 cities, the UHI intensity increases with the logarithm of the city size and with the fractal dimension, but decreases with the logarithm of the anisometry. Typically, the size has the strongest influence, followed by the compactness, and the smallest is the influence of the degree to which the cities stretch. Accordingly, from the point of view of UHI alleviation, small, disperse, and stretched cities are preferable. However, such recommendations need to be balanced against e.g. positive agglomeration effects of large cities. Therefore, trade-offs must be made regarding local and global aims.

    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.)

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.

    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.

    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.

  20. 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 Cultural tourism associates itself with complex issues of dealing with urban memory. As a connotative communication channel, tourism sites and monuments are a perspective through which a city speaks for itself. A number of tourist destinations in the former GDR state faced drastic changes in their tourism management after the national unification of Germany. Which voice does the cultural heritage contain in these cities along its dissonant history and how the local perceptions on the heritage have been altered in the last 25 years are the main subjects of this research. Based on the former studies on the topic of 'heritage and urban identity', this paper explores the relation between architectural heritage management and the dwellers' perceptions on the heritage since the removal of visa controls between GDR and BDR in 1989. Compared to the economic and political studies after the German reunification, socio-cultural issues on local identity and cultural re-adaption process have not been much discussed. Taking three exemplary cities in Thuringia (Eisenach, Gotha and Weimar, the document analysis of the conceptual changes in cultural tourism management and qualitative interviews on both authorities and residents will be done. By providing empirical data on the ongoing German governance, the author attempts to explore the role of cultural heritage in Germany's urban resilience. Furthermore, this research aims to contribute to the contemporary agenda on cultural tourism management in multi-identity societies over international borders.

    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.

    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.

    Full Text Available In the world the interconnection of national economies and internationalization of economic processes occur. In turbulent changing business environment only those companies that understand the current trends in global economy may survive, develop and prosper. Therefore, the issue of internationalization for most companies becomes to be more important and the process of in­ter­na­tio­na­li­za­tion is the way how to stand this increasingly competitive environment. In presented contribution, the attention is paid to issues of internationalization of Slovak food industry enterprises such as their way of business internationalization, percentage share of foreign - trading activities on overall business activity, company evaluation of business internationalization or barriers of foreign markets pe­ne­tra­tion that researched companies have to deal with. Small and medium-sized enterprises (SMEs are the engine of the Slovak economy, generator of development, innovation, growth and they employ more than 60% of employees. Almost all businesses operating in agri-food complex have character of small and medium enterprises. The results of carried research have shown that small and medium-sized companies are considered to be successful in operation on foreign markets in surrounding European countries.

  5. 政府角色与中小微企业发展——基于江苏省13个地级市4574家企业调研数据%THE ROLE OF GOVERNMENT AND THE DEVELOPMENT OF MEDIUM SMALL AND MICRO-SIZED ENTERPRISE——Based on the Survey Data of 13 Prefecture-level Cities in Jiangsu Province

    Based on the background of economic growth from factor-driven to innovation-driven, this paper explores the different effect of government roles in medium small and micro-sized enterprises from a historical and logical view, and uses the survey data of 13 prefecture-level cities of Jiangsu province to test the hypotheses by ordered Probit model.The results show as follows.The direct support policies such as special subsidies and tax incentives can significantly increase the profitability and innovation advantage, so does the government efficiency or service level, which represents indirect support policies.What`s more, different government`s roles play a number of different functions in the innovation and profit ability, the marginal effect of improving government efficiency or service level is larger than tax incentives and special subsidies.Therefore, as economic growth is mainly driven by innovation instead of by factors, the government should not only offer a variety of direct support measures, but also have to adjust their roles, converting from direct support to indirect management and services.%本文基于经济增长由要素驱动到创新驱动的大背景,从历史和逻辑的角度演进,探寻不同政府角色在中小微企业发展中的差异性作用,并采用江苏省13个地级市调研数据,利用Ordered Probit回归模型检验理论假说.结果表明:以专项补贴、税收优惠为代表的直接支持政策和以政府效率或服务水平为代表的间接支持政策都能显著增加企业的盈利和创新优势.政府不同角色带来的盈利效应和创新效应是有差异的,政府效率或服务水平对于企业创新和盈利的边际效应均大于税收优惠和专项补贴.因此,创新驱动型经济中,政府不仅仅是为中小微企业发展提供各种直接支持措施,更要调整其角色定位,从直接扶持转换为间接治理和服务.

    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 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

    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

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

    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

    Full Text Available The aim of the research is estimation of regularities and tendencies, characteristic for modern sectoral structure of small and mediumsized business in Russia. The subject of the research is a set of processes of structural changes on the types of economic activities of such enterprises, as well as the differentiation of the number of employees in enterprises. The research methodology included consideration of aggregates of subjects of small and medium-sized business, formed according to sectoral and territorial features. As the initial data used the official statistical information, which was obtain in the course of total observation of the activities of small and medium-sized businesses in 2010 and 2015. The study was conducted on indicators characterizing the full range of legal entities and individual entrepreneurs in the country. The materiality of structural changes was carried out on the basis of the Ryabtsev index. Modeling the differentiation of the values of the number of employees per enterprise was based on the development of density normal distribution functions. According to the hypothesis it is assumed that the differentiation of the number of employees working in enterprises depend on six main types of economic activity and on the subjects of Russia. Based on the results of the study was proved that there are no significant structural changes for the period from 2010 to 2015, both in terms of the number of enterprises and the number of their employees. Based on the results of the simulation, the average values of the number of employees for the six main types of activity were established, as well as the intervals for changing these indicators for the aggregates of small and medium-sized enterprises located in the majority of the country's subjects. The results of research can be used in the performance of scientific works related to the justification of the expected number and number of employees of enterprises, the formation of

    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

    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.

    Large long pulse tokamak fusion experiments require the use of superconducting poloidal field (PF) coils. In the past not much attention has been paid to the development of such coils. Therefore a development programme has been initiated recently at KfK. In this report start with summarizing the relevant PF coil parameters of some medium and large size tokamaks presently under construction or design, respectively. The most important areas of research and development work are deduced from these parameters. Design considerations and first experimental results concerning low loss conductors, cooling concepts and structural components are given

    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

    The thesis that large scale urban areas result in greater efficiency, reduced costs, and a better quality of life is reexamined. The environmental and social costs are measured for different scales of settlement. The desirability and perceived problems of a particular place are examined in relation to size of place. The consequences of population decline are considered. New York city is described as providing both opportunities in employment, shopping, and cultural activities as well as a high cost of living, crime, and pollution. The historical development of large cities in the US is described. Immigration has contributed to a greater concentration of population than would have otherwise have occurred. The spatial proximity of goods and services argument (agglomeration economies) has changed with advancements in technology such as roads, trucking, and electronic communication. There is no optimal city size. The overall effect of agglomeration can be assessed by determining whether the markets for goods and labor are adequate to maximize well-being and balance the negative and positive aspects of urbanization. The environmental costs of cities increase with size when air quality, water quality, sewage treatment, and hazardous waste disposal is considered. Smaller scale and lower density cities have the advantages of a lower concentration of pollutants. Also, mobilization for program support is easier with homogenous population. Lower population growth in large cities would contribute to a higher quality of life, since large metropolitan areas have a concentration of immigrants, younger age distributions, and minority groups with higher than average birth rates. The negative consequences of decline can be avoided if reduction of population in large cities takes place gradually. For example, poorer quality housing can be removed for open space. Cities should, however, still attract all classes of people with opportunities equally available.

    mass concentration, is also expected to scale the same way. Experimental data for five cities: Mexico City, Mexico; Las Vegas and Reno, NV, USA; Beijing, China; and Delhi, India (the data for the last two cities were obtained from the literature); are in reasonable accord with the model. The scaling relation provided by the model may be considered a useful metric depending on the assumption that specific city conditions (such as latitude, altitude, local meteorological conditions, degree of industrialization, population density, number of cars per capita, city shape, etc.) vary randomly, independent of city size. While more detailed studies (including data from more cities) are needed, we believe that this relatively weak dependence of the pollution concentration on the city population might help to explain why the worsening of urban air quality does not directly lead to a decrease in the rate of growth in city population.

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

    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 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. Compared to manufacturers and service-providing companies where this relation is not statistically significant.

    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.)

    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.

    Full Text Available The key factor of enterprise in order to still growth and developed is customer. The customer will give the value to the enterprise in the form of profit. Therefore, enterprises must be able to establish an sustainable relationship to customer. Since 1990 began to develop what is called Customer Relationship Management (CRM. CRM implements between the development of information technology and customer-centric views. The development of technology and the human need's to move quickly, CRM evolved into a mobile CRM. The Internet make mobile-CRM easily used to all of enterprise, especially small and medium size enterprise. This article is aim to explain the role and the applicability of mobile CRM to business level conditions of small and medium size enterprises (SMEs. The presence of mobile phone operating system that is flexible (android system, the internet cost of affordable and the social media applications as analogy of user interface in making mobile CRM application. CRM mobile application can be downloaded or installed through the app store with ease. It encourages mobile-CRM benefit's rather than as a function of customer data collection but became a window for customer information. In addition, the database can be analysis and relate to customer activity. Mobile CRM applications can take advantage of cross selling methods.

    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.

    Full Text Available Tourism is the world’s largest industry and makes a major contribution to the economies of most developed and developing countries. Tourism as an important socio-economical phenomenon is characterized with distinctly largeness and dynamic development that results with many positive direct as well as indirect economical effects. That is a measure for increasing of possibilities of encouragement of the total economical development through tourism development. Tourism generates income from consumption of goods and services by tourists as well as taxes on businesses in the tourism industry, provides employment in services related to tourism, but also creates jobs in the tertiary sector, generates growth of primary and secondary sectors of the industry as result of multiplicative effect. In this context especially are important small and medium tourism enterprises which dominate in the tourism destinations according to their number, originating a variety of benefits for the tourism destinations by providing direct contact with tourists and by encouraging tourist for spending in a local community. The aim of this paper is to point out the importance of small and mediumsized enterprises in general and especially in the field of tourism for increasing economic development in the national economy with particular reference on the territory of the Republic of Macedonia. In this paper, first will be analyzed the term small and medium - sized enterprises in general and then will be explained their application in the field of tourism with highlighting of their strategic advantages for the tourism destinations and overall economic development of the entire national economy. Finally, will be analyzed the role played by SMEs for the economic development of the Republic of Macedonia with a special emphasis on the measures and actions which have to be taken in the future by the competent authorities for further stimulation of their development.

    2018-03-01

    Urbanization alters surface water compared to nonurban landscapes, yet little is known regarding how basic aquatic ecosystem characteristics, such as the abundance and impairment of surface water, differ with population size or regional context. This study examined the abundance, scaling, and impairment of surface water by quantifying the stream length, water body area, and impaired stream length for 3520 cities in the United States with populations from 2500 to 18 million. Stream length, water body area, and impaired stream length were quantified using the National Hydrography Dataset and the EPA's 303(d) list. These metrics were scaled with population and city area using single and piecewise power-law models and related to biophysical factors (precipitation, topography) and land cover. Results show that abundance of stream length and water body area in cities actually increases with city area; however, the per person abundance decreases with population size. Relative to population, impaired stream length did not increase until city populations were > 25,000 people, then scaled linearly with population. Some variation in abundance and impairment was explained by biophysical context and land cover. Development intensity correlated with stream density and impairment; however, those relationships depended on the orientation of the land covers. When high intensity development occupied the local elevation highs (+ 15 m) and undeveloped land the elevation lows, the percentage of impaired streams was less than the opposite land cover orientation (- 15 m) or very flat land. These results show that surface water abundance and impairment across contiguous US cities are influenced by city size and by biophysical setting interacting with land cover intensity.

    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

    indicators of tuberculosis morbidity and mortality in the city of São José do Rio Preto, Brazil from 1985 to 2003, compared with those in the state of São Paulo and in Brazil at large, and to determine the relationship between the risk of occurrence and socioeconomic level. METHOD: The following official information systems were utilized: the Sistema de Informação de Mortalidade (SIM, Mortality database, the Notificação de Tuberculose (Epi-Tb, Tuberculosis Notification database, the Sistema de Informação de Agravos de Notificação (SINAN, Case-registry database, the Departamento de Informação e Informática do Sistema Único de Saúde (DATASUS, Information Department of the Brazilian Health Ministry and the Instituto Brasileiro de Geografia e Estatística (IBGE, Brazilian Institute of Geography and Statistics database. New cases reported in 2003 in the urban area were georeferenced and analyzed. A map of the sectors, each classified as representing one of three socioeconomic classes, was drawn up, showing the respective tuberculosis incidence coefficients. RESULTS: Comparing Brazil as a whole to the state of São Paulo, total incidence coefficients and mortality rates were similar, as were gender-related values. In the city of São José do Rio Preto the rates were consistently lower. The proportion of cases presenting tuberculosis/human immunodeficiency virus coinfection varied from 29% to 37%. In 2002, 59% and 65% of tuberculosis-only and coinfected tuberculosis patients, respectively, were under supervised treatment, with a cure rate of 81% and a treatment-abandonment rate of 1%. The risk of developing active tuberculosis was three times higher in the area presenting the lowest socioeconomic levels. CONCLUSION: Identification of the areas with different levels of risks for tuberculosis enables the Municipal Health Department to deal with the peculiarities of each region and to prioritize those presenting higher incidences of the disease.

    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.

    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 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.

    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.

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

    Full Text Available 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.

      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.

    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.

    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. Keywords: company strategy; strategic information systems planning; small and mediumsized enterprises; SME sustainability; stakeholders and management; Viewpoint Training and Consulting

    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.

    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.

    The Project uses state-of-the-art computer science to extend the benefits of Building Automation Systems (BAS) typically found in large buildings (>100,000 square foot) to medium-sized commercial buildings (<50,000 sq ft). The BAS developed in this project, termed OpenBAS, uses an open-source and open software architecture platform, user interface, and plug-and-play control devices to facilitate adoption of energy efficiency strategies in the commercial building sector throughout the United States. At the heart of this “turn key” BAS is the platform with three types of controllers—thermostat, lighting controller, and general controller—that are easily “discovered” by the platform in a plug-and-play fashion. The user interface showcases the platform and provides the control system set-up, system status display and means of automatically mapping the control points in the system.

    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.

    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?

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

    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.

    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.

    Full Text Available The International Financial Reporting Standard for Small and Medium-sized entities (IFRS for SMEs was published as a standard by the International Accounting Standards Board (IASB during July 2009. During 2007 South Africa became one of the first countries and the first country in Africa to early accept the proposed accounting standard (exposure draft of an IFRS for SMEs. The accounting standard will probably also be accepted by numerous other countries. The aim of this article is to investigate the applicability of this accounting standard. The results indicated that the IFRS for SMEs remains too comprehensive for the majority of small companies. The IFRS for SMEs does not satisfy the needs of South African users of small company financial statements, and as a result the accounting requirements should be simplified.

    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.

    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.

    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

    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

  17. Modeling fractal structure of city-size distributions using correlation functions.

    Chen, Yanguang

    2011-01-01

    Zipf's law is one the most conspicuous empirical facts for cities, however, there is no convincing explanation for the scaling relation between rank and size and its scaling exponent. Using the idea from general fractals and scaling, I propose a dual competition hypothesis of city development to explain the value intervals and the special value, 1, of the power exponent. Zipf's law and Pareto's law can be mathematically transformed into one another, but represent different processes of urban evolution, respectively. Based on the Pareto distribution, a frequency correlation function can be constructed. By scaling analysis and multifractals spectrum, the parameter interval of Pareto exponent is derived as (0.5, 1]; Based on the Zipf distribution, a size correlation function can be built, and it is opposite to the first one. By the second correlation function and multifractals notion, the Pareto exponent interval is derived as [1, 2). Thus the process of urban evolution falls into two effects: one is the Pareto effect indicating city number increase (external complexity), and the other the Zipf effect indicating city size growth (internal complexity). Because of struggle of the two effects, the scaling exponent varies from 0.5 to 2; but if the two effects reach equilibrium with each other, the scaling exponent approaches 1. A series of mathematical experiments on hierarchical correlation are employed to verify the models and a conclusion can be drawn that if cities in a given region follow Zipf's law, the frequency and size correlations will follow the scaling law. This theory can be generalized to interpret the inverse power-law distributions in various fields of physical and social sciences.

    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.

  19. 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.

    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.

    In this paper, the level of exposure to broadband radiofrequency electromagnetic field in a mid-size European city was evaluated in accordance with the International Commission on Non-ionizing Radiation Protection guidelines from 1998. With the aim to analyse all the potential electromagnetic waves present in the city up to 18GHz, a total of 271 locations distributed along Terrassa (Spain) have been measured. To show the results in an easy-to-interpret way by the citizen, the results have been represented in a set of raster maps. The measurement results obtained showed that the electromagnetic wave measured in all broadband frequency range along the city is much lower than the safety level according to the international regulations for both public and occupational sectors.

    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.

    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.

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

    Full Text Available This paper presents the results of a quantitative study in the Czech Republic to understand travellers’ attitudes towards and motivation to use different means of transport. Two Czech cities, Olomouc and Ostrava, are compared from the point of view of factors influencing spatial and temporal patterns and citizen’s selection of transport mode and transport behaviour (range and daily movements of the population, perception of the quality of public transport etc.. The data for the analysis were obtained from the survey with more than 500 respondents in each city. Spatial and temporal behaviour represented by the pattern of the movement in Olomouc and Ostrava city was identified by statistical and visual analytics methods. Based on a case study of two cities of a different size, we conclude that the size and shape of the city centre (spatial structure influence not only the distances travelled but also the average speed of public transportation (slower for a smaller city. Distances and choice of transport mode also vary with the density of urban areas but can also be influenced by the spatial structure of the city. The walking distance to a public transport stop does not influence the most frequently used mode of transport. Temporal patterns in both cities are very similar and are not dependent on city size or city spatial structure. The spatial patterns of the car and public transport flows are similar in both cities. Different patterns can be observed for walking and shopping routes.

    The current study was designed to determine whether the indoor air pollution in a hemodialysis room (HD) was different from that of other comparable areas in a hospital. Five air monitor samplers were hung on the ceiling and placed on the table in both the HD and general ward nursing stations, respectively. In addition, five samplers were placed in the nurse's breathing zone of the HD and the general ward, respectively. Ten air monitor samplers were also placed on the edge of the bed in the HD, which represented the patient's breathing zone. The levels of benzene and toluene were analyzed by GC/MS. In the general ward, the toluene concentration was significantly higher in the nurse breathing zone than that for the ceiling or table samples (p=0.001). The benzene concentration was also significantly higher in the general ward nurse breathing zone than that in the HD (p=0.006). In addition, the benzene concentrations on the table were higher at the general ward as compared to the HD (p=0.028), but there was no significant difference between the ceiling, general ward station and HD. Both the benzene and toluene concentrations in the HD appear to be more affected by the outdoor atmospheric conditions than by any potential indoor internal sources.

  11. 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)

  12. 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

    2013-12-15

    This annex describes the development of an open model for simulation and evaluation of the economic features of small and medium sized reactors (SMRs), being undertaken by the Politecnico di Milano in Italy. The model aims at establishing a comparative assessment of SMRs versus large reactors (LRs) as its final output. The model will allow assessment of the competitiveness of SMRs under different deployment and application conditions. The distinctive attributes of SMRs such as replication, scalability, reversibility and standardization are briefly described below. The features of SMRs impacting the domains of generation costs (co-siting economies, learning economies, technical economies, mass production and factory fabrication economies), deployment conditions (market matching, market suitability, reduced entry barriers) and financial costs (lower financial distress, reduced risk premium) are addressed before explaining the model architecture. Other state of the art models in this regard are also discussed, along with their respective attributes. The special features of the SMR model being developed are discussed. At the current stage of research, selected elements of the generation costs are modelled analytically. Provisions for adapting financial and external costs from other contemporary models and integrating the same into the main framework are being established. The model has been realized as a code, and the updated version of this code is used in the case studies of SMR competitiveness in different applications, carried out within the IAEA project Common Technology and Issues for SMRs.

    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.

    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

    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.

    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.

  18. Financing innovative small and medium-sized enterprises in times of crisis

    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 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.

    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.

    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

    Full Text Available Main directions of development of small and medium-sized enterprises in Ukrainian agriculture are examined. 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.

    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.

    A random sample of managers of small and medium-sized enterprises (SMEs) was selected from a database of businesses in Sheffield, UK. They were invited to take part in a study to evaluate the provision and perception of occupational health in SMEs in Sheffield. The study used an interviewer-led questionnaire, which collected quantitative and qualitative data; each interview took approximately 40 min to complete. Several approaches to recruitment were adopted during the study. Twenty-eight managers were interviewed over the 6 month study period. All of the SMEs employed advisor; and 10.8% employed a part-time occupational health nurse. Twenty-five per cent had a nominated person responsible for occupational health and 67% thought that a doctor or nurse would be the best person to provide an occupational health service. Twenty-eight per cent of the companies carried out some form of pre-employment screening and 14.2% carried out health promotion. Fifteen (53.5%) collected some form of health related absence data. Eight companies (28.6%) organized a formal induction programme for all new employees. Further work should be undertaken in an attempt to improve access to local industry and particularly to SMEs. This study has clearly shown that access is possible, but different strategies of approach were required before a workable strategy could be found. Undoubtedly, this access can be improved by better understanding of the interaction between researchers, occupational health providers and local managers of SMEs.

    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

    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.

    In the last few years, the distributed energy production from small wind turbines (i.e.<200 kWp) has developed into a relevant business opportunity for different investors in Italy. The market, especially in Italy, has rapidly grown, achieving 9 MWp only in 2011, with an increase from 1.5 MW in 2009 to 13.3 MW at the end of 2011. This paper reports the results of a case study on the installation of several small wind turbines. It aims to provide an analysis of the conditions in Italy that make it possible to install these machines and offer a reliable reference for designing, planning, and controlling small wind turbine projects while focusing on the strategic variables of time, cost, and quality used by typical enterprises in the investment projects. The results are relevant to investors as well as engineering, procurement, and construction companies involved in this new sector, which must understand Italy’s renewable energy policy and its effects in practice. Moreover, certain national energy policy conclusions are reported and discussed in this paper. To properly study the sector, the data on time, cost and quality are analysed using typical project management tools. - Highlights: • Focus on the Italian wind energy sector. • Analysis of Italian policy effects. • Focus on small/medium size wind energy machines

    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.

    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.

    Full Text Available The market economy has reduced the number of large enterprises and has determinated the emergence ofa special class like small and medium-sized enterprises. Those companies play a special role in the nationaleconomy, especially through the fact that attract about 65% of employees in Romania, makes significantinvestments, takes approximately 30% of gross value added in the national economy, operates mainly in servicesactivity, are flexible, concerned with development and have the ability to adopt new technologies. The SMEsector has been affected by the crisis, but not in the same measure as large enterprises. This fact is demonstratedby the economic and financial indicators that I have analised, in 2011 SME beeing able to overcome the crisisand to achieve higher performance than in the years before crisis. The SME sector is considered the most activesector of the modern economy, plays a important role in the economic structure of our country, helping to ensureeconomic and social development as it is shown by the strong bond that exist between the GVA in SME sectorand total GVA added to the national economy, demonstrated in the calculations that I have made in this study.

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

    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.)

    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.

    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.

    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

    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.

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

    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.

    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.

    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.

  1. RISK MANAGEMENT IN SMALL AND MEDIUMSIZED ENTERPRISES: A GENDER-SENSITIVE APPROACH

    Directory of Open Access Journals (Sweden)

    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.

    Aim: This article investigates South African small and medium-sized enterprise (SME owners’ intentions to implement an environmental management system based on the theory of planned behaviour. Setting: Although large businesses are clearly of interest with respect to their environmental management, especially given their prominence in many of the most environmentally impactful sectors, the relative neglect of the environmental management of SMEs is disconcerting, given their overall importance in most economies. In addition, very little research used the theory of planned behaviour to empirically test SME owners’ intentions, to implement an environmental management system. Method: A quantitative survey was used to collect primary data from 326 SME owners by a structured questionnaire. Results: Regression analysis results confirmed the influence of SME owners’ attitudes towards an environmental management system and pro-environmental norms on their intention to implement an environmental management system. Perceived behavioural control, however, did not significantly influence the SME owners’ intention to implement an environmental management system. Conclusion: These findings provide valuable insights into the implementation of environmental management systems among South African SMEs. The theory of planned behaviour also seems to be an appropriate means to investigate the intentions of SMEs to implement an environmental management system.

    For the first time in history, the Global population is more urban than rural and the trend is obvious at various scales. Cities do not serve just as dynamic centres of activities, jobs and consumption markets, social interactions and cultural expressions, but also carry the weight of the main environmental problems of current times and the near future. Global Warming, air and water pollution, population growth and recourse constraints, i.e. reduction of carrying capacity of the environment are among the well known ones. The overall aim of this research is to develop mitigation (at various scales) and adaptation systems, tailored to urban settlements. They should be effective at the very local as well as regional levels, assess and introduce innovative urban technologies and policies, reduce ecological footprint of cities and increase recycling efficiency. We propose the empirical method of urban sustainability assessment, that supports our hypothesis that city functioning, the changes in its population and area growth depends on the size, average and internal densities and the geographical form. The existing cities of three regions are examined: Western and Eastern Europe (incl. Russia), Latin America and China. There are fundamental urban developmental differences and also within the first region, namely between EU countries and the Eastern part of European geographical region. The cities are considered not only as some agglomerates of areas with dense population but from the ecological point of view, namely examining inflow of food and energy and outflow of waste products across the boundaries. There are major differences between the patterns of urbanisation in the studied regions, urban systems functioning and resilience. Continuous investigation of these differenced helps building regional scenarios of cities development, population allocation and pollution management for the 21st century.

    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.

    We assessed news media framing of New York City's proposed regulation to prohibit the sale of sugar-sweetened beverages greater than 16 ounces. We conducted a quantitative content analysis of print and television news from within and outside New York City media markets. We examined support for and opposition to the portion-size cap in the news coverage from its May 31, 2012, proposal through the appellate court ruling on July 31, 2013. News coverage corresponded to key events in the policy's evolution. Although most stories mentioned obesity as a problem, a larger proportion used opposing frames (84%) than pro-policy frames (36%). Mention of pro-policy frames shifted toward the policy's effect on special populations. The debate's most prominent frame was the opposing frame that the policy was beyond the government's role (69%). News coverage within and outside the New York City media market was more likely to mention arguments in opposition to than in support of the portion-size cap. Understanding how the news media framed this issue provides important insights for advocates interested in advancing similar measures in other jurisdictions.

  10. The Context and Challenges for Canada’s Mid-Sized Cities

    Directory of Open Access Journals (Sweden)

    Almos T. Tassony

    2017-05-01

    Full Text Available All Canadian cities face fiscal and governance problems unique to their individual sizes, economies, housing situations and population demographics. This paper examines how mid-sized cities, with populations between 300,000 and two million, can strive to innovate, to act autonomously and to implement complex policies and programs within larger constraints — capabilities of which other levels of government need to be more cognizant. Yet, while provincial and federal regulations would seem to often block mid-sized cities’ capabilities for policy-making, they also offer a solid basis from which to operate. Property taxes provide stable revenue sources while constraints on borrowing mean protection for cities’ credit ratings along with access to capital markets. The challenge is forging a workable balance between constraint from without and a move toward autonomy from within. Municipal governments in Canada typically maintain balanced budgets, but they are also subject to restraints on transfer payments imposed by their provincial governments. How the cities then allocate that money is determined by various factors. These include whether they have large populations of immigrants or the elderly to serve, the basis for the local economy — such as whether it is fuelled by resources, manufacturing or service industries — the degree of homelessness, relationships with public-sector unions, and the costs of compliance to federal standards for such things as wastewater. Unfunded liabilities may also put pressure on a city’s payroll and create an actuarial deficit for its pension plans, resulting in tighter provincial scrutiny. A city’s fiscal health can be assessed by the ways in which it meets the basic criteria of sustainability, flexibility and vulnerability. Sustainability measures how well a municipality maintains its financial obligations to creditors and the public via the services it provides. Flexibility entails how much it can

    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)). The Minnesota functionals, M06 (MUE/MSE=3.8/-2.0 kcal/mol) and M06-2X (MUE/MSE=3.5/3.0 kcal/mol), and recently developed ωB97X-D3 (MUE/MSE=3.2/0.2 kcal/mol) and ωB97M-V (MUE/MSE=2.2/1.3 kcal/mol) methods provided significantly better formation enthalpies. Enthalpies of similar quality can also be obtained from some double hybrid methods (B2PLYP-D3 (MUE/MSE=4.7/2.0 kcal/mol), PWPB95-D3 (MUE/MSE=4.3/3.2 kcal/mol), B2T-PLYP (MUE/MSE=4.1/-3.0 kcal/mol) and B2T-PLYP-D (MUE/MSE=3.3/1.7 kcal/mol)).

    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.

    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.

    Highlights: • Uncertainty analysis of reliability of Shutdown System is carried out. • Monte Carlo method of sampling is used. • The effect of various reliability improvement measures of SDS are accounted. - Abstract: In this paper, results are presented on the uncertainty evaluation of the reliability of Shutdown System (SDS) of a Medium Size Fast Breeder Reactor (MSFBR). The reliability analysis results are of Kumar et al. (2005). The failure rate of the components of SDS are taken from International literature and it is assumed that these follow log-normal distribution. Fault tree method is employed to propagate the uncertainty in failure rate from components level to shutdown system level. The beta factor model is used to account different extent of diversity. The Monte Carlo sampling technique is used for the analysis. The results of uncertainty analysis are presented in terms of the probability density function, cumulative distribution function, mean, variance, percentile values, confidence intervals, etc. It is observed that the spread in the probability distribution of SDS failure rate is less than SDS components failure rate and ninety percent values of the failure rate of SDS falls below the target value. As generic values of failure rates are used, sensitivity analysis is performed with respect to failure rate of control and safety rods and beta factor. It is discovered that a large increase in failure rate of SDS rods is not carried to SDS system failure proportionately. The failure rate of SDS is very sensitive to the beta factor of common cause failure between the two systems of SDS. The results of the study provide insight in the propagation of uncertainty in the failure rate of SDS components to failure rate of shutdown system.

  16. 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.

    Integrating the plasma core performance with an edge and scrape-off layer (SOL) that leads to tolerable heat and particle loads on the wall is a major challenge. The new European medium size tokamak task force (EU-MST) coordinates research on ASDEX Upgrade (AUG), MAST and TCV. This multi-machine approach within EU-MST, covering a wide parameter range, is instrumental to progress in the field, as ITER and DEMO core/pedestal and SOL parameters are not achievable simultaneously in present day devices. A two prong approach is adopted. On the one hand, scenarios with tolerable transient heat and particle loads, including active edge localised mode (ELM) control are developed. On the other hand, divertor solutions including advanced magnetic configurations are studied. Considerable progress has been made on both approaches, in particular in the fields of: ELM control with resonant magnetic perturbations (RMP), small ELM regimes, detachment onset and control, as well as filamentary scrape-off-layer transport. For example full ELM suppression has now been achieved on AUG at low collisionality with n  =  2 RMP maintaining good confinement {{H}\\text{H≤ft(98,\\text{y}2\\right)}}≈ 0.95 . Advances have been made with respect to detachment onset and control. Studies in advanced divertor configurations (Snowflake, Super-X and X-point target divertor) shed new light on SOL physics. Cross field filamentary transport has been characterised in a wide parameter regime on AUG, MAST and TCV progressing the theoretical and experimental understanding crucial for predicting first wall loads in ITER and DEMO. Conditions in the SOL also play a crucial role for ELM stability and access to small ELM regimes. In the future we will refer to the author list of the paper as the EUROfusion MST1 Team.

    Full Text Available The main purpose of the present paper is to identify the framework and the necessary conditions for the small and medium sized enterprises (SMEs to be able to adopt the strategic marketing planning. Also, the paper aims to underline the importance of the strategic marketing planning and the manner in which the SMEs can adopt, implement and operationalize the strategic marketing planning instruments, whose correct understanding and usage ensure the capacity to generate competitive advantage, the key element both from the perspective of the fierce competition and the perspective of the future development of the SMEs. Within SMEs the implementation of marketing becomes an evident requirment, mostly due to the relationship that these have with the market, thus, leading towards market orientation of the activities, a new approach developed by the marketing vision on managing the activities from these types of organizations. Regarded upon, from the marketing perspective, the activities from the SMEs, especially the marketing activities, cannot take place randomly. Resource allocation, a characteristic of these types of organizations, and the objectives with regards to superior customer needs satisfaction and economic efficiency maximization, claim thorough plannification and deployment of the activities in a sequence that represents the implementation of a strategy previously assumed. Within this framework, the strategic marketing planning appears as a complex process employing all scientific instruments that comprise segmentation, positioning and marketing mix. Utilizing the strategic marketing planning within SMEs depends to further extend on marketing integration; process directly related with a series of factors such as the nature of the market, development stage, product type, management quality and the influences of the marketing department of the SME. The implications onto the marketing activities from SMEs are reflected upon each strategic

    Full Text Available The nucleus accumbens (NAc is a critical brain region involved in many reward-related behaviors. The NAc comprises major compartments the core and the shell, which encompass several subterritories. GABAergic medium-sized spiny neurons (MSNs constitute the output neurons of the NAc core and shell. While the functional organization of the NAc core outputs resembles the one described for the dorsal striatum, a simple classification of the NAc shell neurons has been difficult to define due to the complexity of the compartmental segregation of cells. We used a variety of BAC transgenic mice expressing enhanced green fluorescence (EGFP or the Cre-recombinase (Cre under the control of the promoter of dopamine D1, D2, and D3 receptors and of adenosine A2a receptor to dissect the microanatomy of the NAc. Moreover, using various immunological markers we characterized in detail the distribution of MSNs in the mouse NAc. In addition, cell-type specific ERK phosphorylation in the NAc subterritories was analyzed following acute administration of SKF81297 (a D1R-like agonist, quinpirole (a D2R-like agonist, apomorphine (a non-selective DA receptor agonist, raclopride (a D2R-like antagonist, and psychostimulant drugs, including cocaine and d-amphetamine. Each drug generated a unique topography and cell-type specific activation of ERK in the NAc. Our results show the existence of marked differences in the receptor expression pattern and functional activation of MSNs within the shell subterritories. This study emphasizes the anatomical and functional heterogeneity of the NAc, which will have to be considered in its further study.

    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)

    Luciferase is one of the most commonly used reporter enzymes in the field of molecular imaging. D-luciferin is known as the substrate for luciferase enzyme and its cost is very expensive. Therefore, the bioluminescence molecular imaging study has been allowed in small animals such as mice and rats. In this current study, we validated local injection of D-luciferin in articular capsule for bioluminescence imaging in rabbits. Chondrocytes were cultured and infected by replication-defective adenoviral vector encoding firefly luciferase. And then was performed different method of chondrocyte cell injection and transplantation into the knee of rabbits. The rabbits underwent imaging by cooled CCD camera after local injection of D-luciferin (3mg) into experimental knee joint as well as contralateral normal knee joint on days 1, 5, 7, 9. We sought whether optimal imaging signal was acquired by using cooled CCD camera after local injection of D-luciferin. We successfully visualized injected or transplanted cells in knee joint by local injection of D-luciferin. Total photon flux (7.86E+08 p/s/cm{sup 2}/sr) from the knee joint transplanted with cells approximately increased 10-fold more than (9.43E+07p/s/cm{sup 2}/sr) that from injected knee joints until 7 day. Imaging signal was observed in transplanted joints until day 9 after surgery while signal from injected knee was observed by day 7 after injection. We successfully carried out bioluminescence imaging study with medium sized animal by local injection of small amount of D-luciferin. Survival of chondrocytes were prolonged when surgically transplanted in joints than when directly injected in joint space.

    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.

    2017-06-01

    It was known that hydrological regime was the main influencing factor of river ecosystem, but the regime of different flow rates of urban rivers was poorly understood. We collected daily inflows at the Huangtai station of the Xiaoqing River from 1960 to 2014 and divided the data into three periods. Then we calculated hydrological parameters by the method of EFCs (Environmental Flow Components) and analyzed the tendency and change rates of each component respectively in the three periods. Combined with the ecological significance of environmental flow components, we identified the small and medium flood had the greatest impact on the river regime and ecosystem. And then we used the hydraulic parameters in the good ecosystem period as control conditions, to calculate the ecological threshold of the flow component under the current situation. This study could provide technical support for restoring and improving hydrological regime and ecological environment of the Xiaoqing River in Jinan city.

  18. 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

  19. NEW APPROACHES TO CUSTOMER BASE SEGMENTATION FOR SMALL AND MEDIUM-SIZED ENTERPRISES

    Directory of Open Access Journals (Sweden)

    2012-12-01

    Full Text Available The primary purpose of this paper is to explore current praxis and theory related to customer segmentation and to offer an approach which is best suited for small and medium sized enterprises. The proposed solution is the result of an exploratory research aiming to recognize the main variables which influence the practice of segmenting the customer base and to study the most applied alternatives available for all types of enterprises. The research has been performed by studying a large set of secondary data, scientific literature and case studies regarding smaller companies from the European Union. The result of the research consists in an original approach to customer base segmentation, which combines aspects belonging to different well spread practices and applies them to the specific needs of a small or medium company, which typically has limited marketing resources in general and targeted marketing resources in particular. The significance of the proposed customer base segmentation approach lies in the fact that, even though smaller enterprises are in most economies the greatest in number compared to large companies, most of the literature on targeting practices has focused primarily on big companies dealing with a very large clientele, while the case of the smaller companies has been to some extent unfairly neglected. Targeted marketing is becoming more and more important for all types of companies nowadays, as a result of technology advances which make targeted communication easier and less expensive than in the past and also due to the fact that broad-based media have decreased their impact over the years. For a very large proportion of smaller companies, directing their marketing budgets towards targeted campaigns is a clever initiative, as broad based approaches are in many cases less effective and much more expensive. Targeted marketing stratagems are generally related to high tech domains such as artificial intelligence, data mining

    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 (<100,000 sf) commercial buildings (SMBs) represent over 95% of the U.S. commercial building stock and consume over 60% of total site energy consumption. Many of these buildings use rudimentary controls that are mostly manual, with limited scheduling capability, no monitoring or failure management. Therefore, many of these buildings are operated inefficiently and consume excess energy. SMBs typically utilize packaged rooftop units (RTUs) that are controlled by an individual thermostat. There is increased urgency to improve the operating efficiency of existing commercial building stock in the U.S. for many reasons, chief among them is to mitigate the climate change impacts. Studies have shown that managing set points and schedules of the RTUs will result in up to 20% energy and cost savings. Another problem associated with RTUs is short-cycling, where an RTU goes through ON and OFF cycles too frequently. Excessive cycling can lead to excessive wear and lead to premature failure of the compressor or its components. The short cycling can result in a significantly decreased average efficiency (up to 10%), even if there are no physical failures in the equipment. Also, SMBs use a time-of-day scheduling is to start the RTUs before the building will be occupied and shut it off when unoccupied. Ensuring correct use of the zone set points and eliminating frequent cycling of RTUs thereby leading to persistent building operations can significantly increase the operational efficiency of the SMBs. A growing trend is to use low-cost control infrastructure that can enable scalable and cost-effective intelligent building operations. The work reported in this report describes three algorithms for detecting the zone set point temperature, RTU cycling rate and occupancy schedule detection that can be deployed on the low-cost infrastructure. These algorithms only require the zone temperature data for detection. The algorithms have been tested and validated using

    On 15 December 2005, the European Medicines Agency (EMEA) launched an "SME Office" to provide financial and administrative assistance to micro-, small- and medium-sized enterprises (SMEs), with the aim of promoting innovation and the development of new human and veterinary medicinal products by SMEs. According to current EU definition of an SME, companies with fewer than 250 employees, and an annual turnover of not more than 50 million euro or an annual balance sheet total of not more than 43 million euro, are eligible for assistance from the SME Office. Incentives available from the EMEA for SMEs, include: Administrative and procedural assistance from SME Office within the Agency; Fee reductions (90%) for scientific advice and inspections; Fee exemptions for certain administrative services (excluding parallel distribution); Deferral of the fee payable for an application for marketing authorisation or related inspection until after the grant of the marketing authorisation; Conditional fee exemption where scientific advice followed and marketing application is unsuccessful; Assistance with translations of the product information documents. At the end of May 2009, more than 380 companies from 21 countries across the European Economic Area (EEA) had SME status assigned by the EMEA. The large majority of companies are developing medicinal products for human use, 16 are veterinary companies, 15 companies are developing products for both human and veterinary use and 38 are regulatory consultants. Since the SME initiative started the Agency has processed more than 130 requests for scientific advice with fee reductions totalling of 6.9 million euro. Regulatory assistance has been provided to more than 170 companies and 12 companies have benefited from the SME translation service. Stakeholders have acknowledged the significant role the SME Office now plays as a service provider. In the period between January 2006 and June 2009, 34 applications for marketing authorization

    Full Text Available Purpose: The main purpose of this paper is to examine perceived impediments to export involvement among non-exporting small and medium sized firms (SME's in Malawi. The study also examines levels of interest in exporting among the firms. Problem investigated: Many countries have programs aimed at promoting export involvement among SME's. Despite this, most SME's continue to ignore exporting as a viable business strategy. Information on perceived impediments to export involvement especially from the non-exporters' perspective is often lacking hence the need for this study. Methodology: Data was collected from 80 owner managers of non-exporting SME's. A structured questionnaire was the main instrument used to collect data. Personal interviews were also held with managers for the purposes of probing their answers to the questions in the questionnaire. Statistical Package for Social Science (SPSS version 18 was used to analyse the quantitative data obtained from use of the structured questionnaire. Qualitative data obtained through personal interviews was analysed used thematic analysis. Findings: The findings of the study showed significant levels of interest in exporting among the firms. The majority of the owner managers indicated willingness to exploit export opportunities that may be readily available to them. The findings however showed that just over half of the respondents had discussed or investigated the possibility of exporting before. On impediments to exporting, the findings showed that managers perceive many factors as important impediments to their firm's involvement in exporting. The top two most important impediments were internal to the firm and related to human resource issues. They included insufficient knowledge about export opportunities and lack of personnel knowledgeable in exporting. Originality and value of the research: A review of literature shows that most export promotion studies tend to focus more on issues relating to

    Full Text Available At the time of increasing globalization and homogenization of the global markets, the development of information infrastructure technology and world market becomes accessible not only to large multinational companies but also for small and medium-sized enterprises (SMEs. This has resulted in increasing competition in the domestic market which domestic firms have to face. Therefore the pro­cess of internationalization of business is a step that allows businesses performing their activities in the domestic market to enter foreign markets and to exploit the opportunities and potential which these markets offer. The paper is focused on the draft of the method for quantification of the factors, which determine the success of the SMEs in foreign markets. In the proposed method the multidimensional assessment of indicators of success of SMEs in foreign markets are used, ie. not only the proportion of sales from exports is observed, but also the profitability of international activities in an absolute and in a relative rate. Other indicators of success are the satisfaction of the company management with international activities and the success of achieving defined targets for business activities in foreign markets. Evaluation is made up of both the objective and the subjective indicators of success. Among the objective indicators of success is included the intensity of international activities of SMEs, which is detected as the sum of revenues generated from international activities in relation to total sales company, the profitability of international activities, (ie. whether the foreign activities are profitable or not, and the relative profitability of international activities, where it is ascertained whether the foreign activities generate higher profit than the activities at the domestic market. The next subjective indicator of success is the success of objectives - it was found how many objectives related to operations in foreign markets has been

    Full Text Available The purpose of this study was to examine internationalisation barriers of manufacturing SMEs operating in Leather and Leather Products Industry located in the capital city of Ethiopia. The small and medium sized enterprises (SMEs sector in Ethiopia is a significant group within the economy in terms of firm numbers and total employment. However, the SMEs sector’s share of exports is disproportionately small, which raised considerable research concerns. Firm export propensity was the dependent variable and internal and external export barrier factors were used as explanatory variables. The study was conducted through mixed research design of quantitative survey and case study. From the population of manufacturing SMEs operating in the Leather and Leather products Industry, a sample was selected through the use of stratified random sampling to ensure the effective representation of the population of exporting and non-exporting SMEs in the capital of Ethiopia. In order to complement survey results nine (4 exporting and 5 non-exporting SMEs were selected through critical case purposive sampling and an in-depth interviews were conducted. Statistical package for the social sciences (SPSS 20 was used to analyse the quantitative data whereas, qualitative data were analysed manually. Exploratory factor analysis with Varimax rotation and Binary logistic regression analysis are the analytical methods used. The statistical result showed that, logistics problem, insufficient finance, functional barriers, lack of export knowledge and information, procedural barriers and international trade barriers are the most significant obstacles of export trade in Ethiopia. The overall results revealed that explanatory variables used in the analysis significantly predict the dependent variable at 95% confidence level. Taken together, these results prompted the presentation of numerous implications for theory, practice, and future research. Finally, the paper recommended

    2014-01-01

    In the past decades, portion sizes of high-caloric foods and drinks have increased and can be considered an important environmental obesogenic factor. This paper describes a research project in which the feasibility and effectiveness of environmental interventions targeted at portion size was evaluated. The studies that we conducted revealed that portion size labeling, offering a larger variety of portion sizes, and proportional pricing (that is, a comparable price per unit regardless of the size) were considered feasible to implement according to both consumers and point-of-purchase representatives. Studies into the effectiveness of these interventions demonstrated that the impact of portion size labeling on the (intended) consumption of soft drinks was, at most, modest. Furthermore, the introduction of smaller portion sizes of hot meals in worksite cafeterias in addition to the existing size stimulated a moderate number of consumers to replace their large meals by a small meal. Elaborating on these findings, we advocate further research into communication and marketing strategies related to portion size interventions; the development of environmental portion size interventions as well as educational interventions that improve people's ability to deal with a ‘super-sized' environment; the implementation of regulation with respect to portion size labeling, and the use of nudges to stimulate consumers to select healthier portion sizes.

    Over the last 8000 years the Fertile Crescent of the Near East has seen the emergence of urban agglomerations, small scale polities and large territorial empires, all of which had profound effects on settlement patterns. Computational approaches, including the use of remote sensing data, allow us to analyse these changes at unprecedented geographical and temporal scales. Here we employ these techniques to examine and compare long term trends in urbanisation, population and climate records. Maximum city size is used as a proxy for the intensity of urbanisation, whilst population trends are modelled from settlement densities in nine archaeological surveys conducted over the last 30 years across the region. These two measures are then compared with atmospheric moisture levels derived from multiple proxy analyses from two locations close to the study area, Soreq Cave in Israel and Lake Van in south-eastern Turkey, as well as wider literature. The earliest urban sites emerged during a period of relatively high atmospheric moisture levels and conform to a series of size thresholds. However, after the Early Bronze Age maximum urban size and population levels increase rapidly whilst atmospheric moisture declines. We argue that although the initial phase of urbanization may have been linked to climate conditions, we can see a definitive decoupling of climate and settlement patterns after 2000 BC. We relate this phenomenon to changes in socio-economic organisation and integration in large territorial empires. The complex relationships sustaining urban growth during this later period resulted in an increase in system fragility and ultimately impacted on the sustainability of cities in the long term.

    One of the IAEA's statutory objectives is to 'seek to accelerate and enlarge the contribution of atomic energy to peace, health and prosperity throughout the world'. One way this objective is achieved is through the publication of a range of technical series. Two of these are the IAEA Nuclear Energy Series and the IAEA Safety Standards Series. According to Article III.A.6 of the IAEA Statute, the safety standards establish 'standards of safety for protection of health and minimization of danger to life and property.' The safety standards include the Safety Fundamentals, Safety Requirements and Safety Guides. These standards are written primarily in a regulatory style, and are binding on the IAEA for its own programmes. The principal users are the regulatory bodies in Member States and other national authorities. The IAEA Nuclear Energy Series comprises reports designed to encourage and assist R and D on, and application of, nuclear energy for peaceful uses. This includes practical examples to be used by owners and operators of utilities in Member States, implementing organizations, academia, and government officials, among others. This information is presented in guides, reports on technology status and advances, and best practices for peaceful uses of nuclear energy based on inputs from international experts. The IAEA Nuclear Energy Series complements the IAEA Safety Standards Series. To be competitive in anticipated markets, small and medium sized reactors (SMRs) rely on design and deployment approaches that are able to offset the adverse impacts of economy of scale. Such approaches include design simplification resulting from the application of safety design features that are the most appropriate for reactors of smaller capacity; the economy of mass production of multiple prefabricated modules; the option of incremental capacity increase, with possible benefits resulting from accelerated learning; sharing of common equipment and facilities; shorter construction

The analysis was based on the literature available and data obtained from empirical research conducted by the writer. The results show that companies, however in different extent undertake ecological activities willingly. Furthermore, those activities benefit not only in terms of the environmental dimension of CSR, but also in other areas of the organization.

    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.

    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.

    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.

    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.

    We utilize the distribution of PM_2_._5 concentration and population in large cities at the global scale to illustrate the relationship between urbanization and urban air quality. We found: 1) The relationship varies greatly among continents and countries. Large cities in North America, Europe, and Latin America have better air quality than those in other continents, while those in China and India have the worst air quality. 2) The relationships between urban population size and PM_2_._5 concentration in large cities of different continents or countries were different. PM_2_._5 concentration in large cities in North America, Europe, and Latin America showed little fluctuation or a small increasing trend, but those in Africa and India represent a “U” type relationship and in China represent an inverse “U” type relationship. 3) The potential contribution of population to PM_2_._5 concentration was higher in the large cities in China and India, but lower in other large cities. - Highlights: • Urban population and PM_2_._5 concentration varies greatly among regions. • Urban population size increase does not always enhances PM_2_._5 concentration. • Population's potential contribution to PM_2_._5 concentration higher in China. - We utilize the distribution of PM_2_._5 concentration and population in large cities at the global scale to illustrate the relationship between urbanization and urban air quality.

    To reveal the chemical characteristics of size-segregated aerosols in the high-altitude city of Tibetan Plateau, eight-size aerosol samples were collected in Lhasa from March 2013 to February 2014. The annual mean of online PM2.5 was 25.0 ± 16.0 μg m- 3, which was much lower than Asian cities but similar with some European cities. The annual mean concentrations of organic carbon (OC, 7.92 μg m- 3 in PM2.1 and 12.66 μg m- 3 in PM9.0) and elemental carbon (EC, 1.00 μg m- 3 in PM2.1 and 1.21 μg m- 3 in PM9.0) in Lhasa aerosols were considerably lower than those heavily polluted cities such as Beijing and Xi'an, China and Kathmandu, Nepal. Sulfate, NO3-, NH4+ and Ca2 + were 0.75 ± 0.31, 0.82 ± 0.35, 0.38 ± 0.34 and 0.57 ± 0.29 μg m- 3 in fine particles while in coarse particles they were 0.57 ± 0.37, 0.73 ± 0.23, 0.07 ± 0.03 and 2.52 ± 1.37 μg m- 3, respectively. Secondary water-soluble ions composed 35.8% of the total ionic components in fine particles according to the established electroneutrality, while in coarse particles they took up only 9.3%. Ca2 + (40.6%) was the major component of the coarse particles. For seasonality, the concentrations of OC, EC, SO42 -, NH4+, K+, Ca2 +, Mg2 +, Cl- and Na+ presented higher values during late autumn and winter but were relatively lower in spring and summer. Nevertheless, NO3- was considerably higher in summer and autumn, presumably due to increased tourist-vehicle emissions. During winter and spring, [Ca2 +]/[NO3-+ SO42 -] ratios in coarse particles showed higher values of 7.31 and 6.17, respectively, emphasizing the dust influence. [NO3-]/[SO42 -] ratios in fine particles during spring, summer and autumn exceeding 1 indicated that the currently predominant vehicle exhaust makes a greater contribution to the aerosols. While more stationary sources such as coal and biomass burning existed in winter since the [NO3-]/[SO42 -] ratio was less than 1. Different sources and formation processes lead to a bimodal size

    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 Studies related to community ecology of medium and large mammals represent a priority in developing strategies for conservation of their habitats. Due to the significant ecological importance of these species, a concern in relation to anthropogenic pressures arises since their populations are vulnerable to hunting and fragmentation. In this study, we aimed to analyze the diversity of medium and large mammals in a representative area of the Cerrado biome, located in the National Forest of Silvânia, central Brazil, providing insights for future studies on the biodiversity and conservation of Cerrado mammals. Sampling was carried out by linear transects, search for traces, footprint traps and camera traps. We recorded 23 species, among which three are listed in threat categories (e.g., Myrmecophaga tridactyla, Chrysocyon brachyurus and Leopardus tigrinus. We registered 160 records in the study area, where the most frequently recorded species were Didelphis albiventris (30 records and Cerdocyon thous (28 records. Our results indicated that a small protected area of Cerrado can include a large and important percentage of the diversity of mammals in this biome, providing information about richness, abundance, spatial distribution and insights for future studies on the biodiversity and conservation of these biological communities.

    1985-01-01

    The evolution of radiation protection in Switzerland caused the Triemli City Hospital to implement building modifications throughout its 13 years of existence which have not been completed todate. However, modest methods allowed to find practicable solutions which largely comply with today's radiation protection regulation. Radiation protection provisions have been rendered more stringent thus resulting in more jobs. At least one additional staff member is required in order to discharge all supervisory functions required like incorporation controls, controls of cleaning and technical staff for their working correctly, contamination controls of floors and working areas, exit controls of special working clothes, etc. The best solution for the hospital would be to have one health physics man specifically commissioned with and employed for radiation protection.

    The developed countries have been prepared the national innovation for sustainable development for a long time. The international advanced enterprises, such as multinational enterprises, are enhancing the active and strategic environmental management. However, in spite of such changes in the world, small and middle-sized enterprises do not show any substantial changes. It is true that most of enterprises do not recognize the need of environmental management. Although they have intention for environmental improvement, it is also true that they do not have any strength to maintain effective management. Moreover, with over 99% of small and middle-sized enterprises among entire enterprises in Korea, it is hardly possible to establish an effective regulation system. The purpose of this study is to make a policy plan to induce the development of environmental friendly small and middle-sized enterprises under the recognition of such problems. 138 refs., 4 figs., 195 tabs.

    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.

  2. The Perspective of Small and Medium Size Nuclear Power Reactors in the Brazilian Isolated Electricity Grids

    1998-01-01

    As a consequence of the international crisis that has shaken the nuclear industry almost all over the world during the late 1980s, new academic contributions, which could settle a new basis for the nuclear energy in Brazil, have been scarce. This paper aims to partially fulfill this gap. We discuss some perspectives for the nuclear option to regain some prominence in the Brazilian energy matrix. Recent developments in the nuclear industry, including advances in plant design, have been opening interesting markets for small and medium nuclear power reactors (SMNPRs). We access the suitability and feasibility of such new technology in the Brazilian isolated electricity grids. We conclude by saying that, although the difficulties are still huge, SMNPRs may be a good strategy for Brazil to revitalize its nuclear policy. (author)

    Small and medium enterprises (SMEs) are a major source of dynamism, innovation and flexibility for emerging and developing countries, as well as for the economies of the most industrialised nations. However, the survival and growth of SMEs can be difficult in the current competitive business environment and global marketplace. It can be a real challenge to deliver the right product and service at the most opportune time and at the lowest possible cost to the right customer. The challenge stresses the importance of managing cross-boundary relationships between business partners. For gaining a competitive advantage, supply chain management (SCM) is an effective tool to SMEs. Therefore, this paper aims to review the tenet of SCM, its benefits and practices to SMEs.

    For the decades, organizations have endeavored to look for external sources for opportunities to achieve efficient and responsive supply chain with their partners especially for small and medium manufacturers (SMM). In this scenario, supply chain collaboration (SCC) is an interaction between supply chain members with the purpose of utilizes the knowledge and resources of customers and suppliers, and integrates the flows of products and information in order to achieve a common goal and obtain mutual benefit. The essential SCC dimensions for SMMs comprised of information sharing, joint knowledge creation, joint decision making, goal congruence and incentive sharing. The successful implementation of SCC can give SMMs an edge over their competitors. This paper aims to introduce a review of SCC practices for SMM. Overall, the findings provide managerial insights for the SMM in SCC implementation owing to resource scarcity and the need to draw SCC in order to ensure a sustainable competitive advantage.

    Full Text Available The use of self-compacting concrete (SCC has been on the rise in recent years. Research on this type of concrete has focused primarily on determining optimal dosage, while durability, particularly for medium strength SCC, has received much less attention. The present study explored the permeability of a number of medium strength (characteristic strength, 30 MPa self-compacting concretes, including SCCs made with common cement, in pursuit of a balance between performance and cost. Pressurised water and mercury intrusion porosimetry tests were conducted to determine concrete behaviour when exposed to aggressive agents. The findings showed that the capillary networks of these concretes are essentially impermeable to aggressive agents.

    El hormigón autocompactante ha experimentado un amplio desarrollo en los últimos años. Los estudios sobre este hormigón se han centrado en obtener dosificaciones óptimas, mientras los relativos a su durabilidad son escasos, especialmente en el caso de hormigones de resistencia moderada. Este trabajo se centra en el estudio de la permeabilidad de distintos hormigones autocompactantes de resistencia moderada (resistencia característica 30 MPa. El estudio incluye hormigones fabricados con cementos comunes, en los que se ha buscado un equilibrio entre prestaciones y precio. Con el fin de estudiar su comportamiento frente a la penetración de agentes agresivos, se han realizado los ensayos de permeabilidad al agua bajo presión y estudio de la porosimetría por intrusión de mercurio. Los resultados de los ensayos ponen de manifiesto el buen comportamiento de estos hormigones frente a la posible penetración de agentes agresivos por la red capilar.

    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.

    2013-01-01

    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 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 application

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

    Directory of Open Access Journals (Sweden)

    Mazur Jolanta

    2016-09-01

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

    The aim of this study is to examine innovative activities in small and medium enterprises (SMEs) in the Malaysian information technology (IT) industry. This study addresses three research questions: 1. What is the innovation pattern among SMEs in the Malaysian IT industry? 2. How significant is interactive learning between SMEs in the Malaysian IT industry and other agents in the innovation system? and 3. What is the role of the government in promoting innovation among SMEs in the Malaysian IT industry? Two approaches were taken to collect data for this study, that is, mail survey and face-to-face interviews. Based on findings from this study, the SMEs in the Malaysian IT industry were divided into four categories, namely, highly innovative, innovative, inventive, and non innovative. The patterns of knowledge acquisition and interactive learning vary among the different categories of firms, and on the whole, vertical linkages with suppliers were found to be the most significant. Finally, support through the provision of funding was considered to be among the most important roles of the government in promoting innovation in SMEs in the Malaysian IT industry. (author)

    Maurício Floriano Galimberti

    2015-12-01

    Full Text Available Implementations of software production processes usually ignore organizational, market, and economical attributes of products that are to be inserted in international markets. Software engineering has begun to deal with the business aspects of software products only recently. The Guide to the Software Engineering Body of Knowledge v3.0 presents two concepts of life cycle: the software development life cycle and the software product life cycle. The second is more concerned with business issues related to software products, but research on those issues is still due. In this sense, this paper aims to answer the following question: what factors allow small and medium software enterprises to offer high value added products in order to enter and remain in the international market? This work selects four research dimensions from literature and explores a number of variables inside those dimensions, which are considered as candidates to help explaining a successful process of active internationalization. The paper presents a multiple case study that shows that although innovation, entrepreneurship, and foreign market knowledge are important dimensions for the active internationalization, networking is not as relevant as it could be thought.

    2016-01-01

    The development of digital technologies for manufacturing has been challenged by the difficulty of navigating the breadth of new technologies available to industry. This difficulty is compounded by technologies developed without a good understanding of the capabilities and limitations of the manufacturing environment, especially within small-to-medium enterprises (SMEs). This paper describes industrial case studies conducted to identify the needs, priorities, and constraints of manufacturing SMEs in the areas of performance measurement, condition monitoring, diagnosis, and prognosis. These case studies focused on contract and original equipment manufacturers with less than 500 employees from several industrial sectors. Solution and equipment providers and National Institute of Standards and Technology (NIST) Hollings Manufacturing Extension Partnership (MEP) centers were also included. Each case study involved discussions with key shop-floor personnel as well as site visits with some participants. The case studies highlight SME's strong need for access to appropriate data to better understand and plan manufacturing operations. They also help define industrially-relevant use cases in several areas of manufacturing operations, including scheduling support, maintenance planning, resource budgeting, and workforce augmentation.

    Full Text Available The entry is aimed at analyzing the process of managing small and medium-sized enterprise, specifically in the Region of South Bohemia. The testing sample included 180 enterprises. The fundamental statistical information about SMEs is included, focusing of the numbers, the size category, and their specialization in the Region of South Bohemia. The research activities were aimed at the steepness of management structures and at their extent on all management levels. The analysis indicates that micro-enterprises prefer one management level, while small and middle-sized enterprises prefer two management levels with the statistic dependence on the size category. In regard to the number of employees on individual management levels, the top positions have from 6 employees up to 30 on the operative level. The general business trend involves a transfer to the functional management structure. With respect to the strategic management and decision- making, enterprises boost an attractive prospect of mainly their own sources. A statistical correlation was proved between the elaborated strategy, the size of the enterprise and number of management levels. A strong correlation between the number of management levels and the aim of the enterprise i.e. the type of organization structure was not proved.

    A multi-fractal framework of urban hierarchies is presented to address the rank-size distribution of cities. The three-parameter Zipf model based on a pair of exponential-type scaling laws is generalized to multi-scale fractal measures. Then according to the equivalent relationship between Zipf's law and Pareto distribution, a set of multi-fractal equations are derived using dual conversion and the Legendre transform. The US city population data coming from the 2000 census are employed to verify the multi-fractal models and the results are satisfying. The multi-fractal measures reveal some strange symmetry regularity of urban systems. While explaining partially the remains of the hierarchical step-like frequency distribution of city sizes suggested by central place theory, the mathematical framework can be interpreted with the entropy-maximizing principle and some related ideas from self-organization

    Full Text Available We analysed yearly estimates of population size data during 2001-2012 for five carnivores species of conservation interest (Ursus arctos, Canis lupus, Lynx lynx, Felis silvestris and Canis aureus. Population size estimations were done by the game management authorities and integrated by the competent authorities on the Ministry of Environment and Climate Change. Trends in data were detected using non-parametric Mann-Kendall test. This test was chosen considering the short length of data series and its usefulness for non-normal distributed data. The trend was tested at three spatial scales: game management units (n=1565, biogeographical region (n=5 and national. Trends depicted for each game management unit were plotted using ArcGIS, resulting species trend distribution maps. For the studied period increasing population trends were observed for Ursus arctos, Canis lupus, Canis aureus and Lynx lynx, while for Felis silvestris there was no trend recorded. Such an analysis in especially useful for conservation proposes, game management and reporting obligations under article 17 of the EC Habitat Directive, using population trend as a proxy for population dynamics. We conclude that the status of the five carnivore species is favourable during the study period.

    Background. When the same dose of iodine is given to all patients when performing abdominal computed tomography (CT) there may be a wide inter-individual variation in contrast medium (CM) enhancement of the liver. Purpose. To evaluate if any of the measures body height (BH), body mass index (BMI), lean body mass (LBM), ideal body weight (IBW), and body surface area (BSA) correlated better than body weight (BW) with hepatic enhancement, and to compare the enhancement when using iodixanol and iomeprol. Material and Methods. One hundred patients referred for standard three-phase CT examination of abdomen were enrolled. Body weight and height were measured at the time of the CT examination. Forty grams of iodine (iodixanol 320 mg I/mL or iomeprol 400 mg I/mL) was injected at a rate of 1.6 g-I/s, followed by a 50 mL saline flush. The late arterial phase was determined by using a semi-automatic smart prep technique with a scan delay of 20 s. The hepatic parenchymal phase started automatically 25 s after the late arterial phase. CM concentration was estimated by placement of regions of interest in aorta (native and late arterial phase) and in liver (native and parenchymal phase). Results. BW (r -0.51 and -0.64), LBM (r = -0.54 and -0.59), and BSA (r -0.54 and -0.65) showed the best correlation coefficients with aortic and hepatic parenchymal enhancement, respectively, without any significant differences between the measures. Comparing iodixanol and iomeprol there was no significant difference in aortic enhancement. The liver enhancement was significantly higher (P < 0.05) using iodixanol than iomeprol. Conclusion. To achieve a consistent hepatic enhancement, CM dose may simply be adjusted to body weight instead of using more complicated calculated parameters based on both weight and height.

    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.

    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

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.

  12. An empirical study on the critical success factors of small to medium sized projects in a South African mining company

    Full Text Available Projects that fail, for whatever reason, can impact negatively on society, organisations, and other stakeholders. A number of researchers have identified various critical success factors (CSFs that can influence the outcome and success of a project. This research therefore aims to determine the CSFs that influence various success measures of small- to medium-sized projects at a South African mining company, Exxaro Resources’ Grootegeluk Coal Mine. Other objectives of this research include determining the extent of the impacts of these CSFs on the different success measures of a project. The investigation suggests that there are correlations among CSFs, and that certain factors impact the outcome of projects far more than others. This research finds that the single most important CSF for small- to medium-sized projects is the selection of a competent project manager. The competent project manager is characterised by a group of interrelated CSF factors: good leadership, commitment, and learning from past experiences. Based on the research results, other CSFs are discussed and explored in order for recommendations to be made on how this mining company, and possibly other organisations, can achieve greater project success.

    Large-scale kinetic simulations of toroidal plasmas based on first principles are called for in studies of transition from low to high confinement mode and internal transport barrier formation in the core plasma. Such processes are best observed and diagnosed in detached plasma conditions in mid-sized tokamaks, so gyrokinetic simulations for these conditions are warranted. A first principles test-particle based kinetic model ELMFIRE[1] has been developed and used in interpretation[1,2] of FT-2 and DIII-D experiments. In this work we summarize progress in Cyclone (DIII-D core) and ASDEX Upgrade pedestal region simulations, and show that in simulations the choice of adiabatic electrons results in quenching of turbulence (copyright 2010 WILEY-VCH Verlag GmbH and Co.

    In 2014, Marshall McCall mapped out our Local Sheet, the cosmic wall containing the Milk Way and Andromeda galaxies. We use the large new Bolshoi-Planck cosmological simulation to investigate how rare our type of Local Sheet is, with 2 nearby halos like those of Milky Way and Andromeda. The conclusion of our investigation is that the occurrence of a pair of galaxies the size of Milky Way and Andromeda near the center of a wall 8 mpc in diameter, with the pair of galaxies within 0.7 mpc/h of each other, is very rare : it makes up only 0.05% of all walls in the simulation.

    2015-01-01

    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.

    2017-09-01

    Full Text Available Objective: The study goal was the investigation of relationships between accelerated internationalisation descriptors and antecedent firm- and entrepreneur-related factors in Polish and Czech SMEs. Research Design & Methods: In order to compare Polish and Czech companies, the data collected in two independent studies were used. The study of 233 Polish companies was conducted with the use of CATI method in 2014; 108 Czech companies were surveyed in 2013/2014 with the use of CAWI method. In both samples half of the surveyed SME-exporters were conforming to the accelerated internationalisation criteria. Findings: In both samples the “global vision” elements and company internationalisation scale and speed were interrelated. In the Polish companies this relationship was moderated by company size. There was the lack of strong positive relationships between innovativeness and internationalisation speed and scale in both samples. Implications & Recommendations:The managerial mindset has a decisive role for accelerated internationalisation in both Czech and Polish SMEs. The innovativeness of offering is not indispensable for fast foreign expansion. Larger companies may expand abroad faster if they have internationally oriented managers. Contribution & Value Added:This work addresses a research gap concerning idiosyncrasies of internationalisation antecedents in Polish and Czech enterprises. As the results show, there is no common internationalisation pattern for Polish and Czech SMEs.

    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.

    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.

    Full Text Available Changes in the South African media and management environment have had distinct influences on especially small to medium-sized mainstream media enterprises (media SMEs which often have to compete with bigger media organisations for the same news stories. Moreover, these media organisations are commonly faced with unique challenges related to human and other resources. This situation adds to the importance of effective and efficient management practices at these media sites. The management practices of first-line news managers in media SMEs are qualitatively and quantitatively evaluated in this paper by considering six managerial competencies found in general management theory. These competencies relate to communication, planning and administration, teamwork; strategic action, global awareness and self-management.

    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.

    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.

    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

    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)

    2016-06-01

    Full Text Available The aim of the paper is to investigate the internationalization (particularly exporting of small and medium-sized enterprises (SMEs taking a sample of United Kingdom (UK SMEs for the use in economic policy, academia and management. It focuses on the critical first and less risky step towards internationalization and separates the motivators into home country and host country. The paper investigates 44 specific, high impact, pre-selected exporting motivators from the literature and tests their effect on the firm’s initial export decision and latest (or sequential export decision. Results show that the first exporting choice affects later exporting choices and both are mostly affected by home country-specific, internal, motivators as opposed to host country-specific reactive motivators. In addition regionalization shows an association as European Union membership of the UK showed a relationship to subsequent entry mode choice. The paper’s results are of use to policy-makers and management.

    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.

    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.

    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.

    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.

    Full Text Available Urban heat islands (UHIs in large cities and different climatic regions have been thoroughly studied; however, their effects are becoming a common concern in smaller cities as well. We assessed UHIs in three tropical cities, analyzing how synoptic conditions, urban morphology, and land cover affect the heat island magnitude. Data gathering involved mobile surveys across Paranavaí (Paraná, Rancharia (São Paulo, and Presidente Prudente (São Paulo, Brazil, during summer evenings (December 2013–January 2014. Temperature data collected over five days in each city point to heat islands with magnitudes up to 6 °C, under calm synoptic conditions, whereas summer average UHI magnitudes peak at 3.7 °C. In addition, UHI magnitudes were higher in areas with closely spaced buildings and few or no trees and building materials that are not appropriate for the region’s climate and thermal comfort.

    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

    Inside the breathable fraction of the atmosphere of Mexico City, the presence of metals in suspended particles, is determined and quantified. The detection was carry out simultaneously in three places of the city, using collectors of the type stacking filter unit (SFU) which allow the separation of particles according to its size. The SFU detectors allow the separation in two size: 'Gross' mass from 2.5 to 1.5 μm and 'fine' mass for particles smallest than 2.5 μm. The analysis of the samples was fulfilled by means of PIXE method. Samples were irradiated with a proton beam, and based in the X-ray spectra the elements were identified and quantified, which allow to establish the temporal behavior of the concentrations per element for gross mass and fine mass in each one of the places of sampling.

    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.

    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.

    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

    Highlights: ► S-CO 2 cycle as candidate for SMS. ► MATLAB code used for S-CO 2 cycle analysis. ► Pressure ratio and split ratio comparison analyzed. - Abstract: The supercritical carbon dioxide (S-CO 2 ) Brayton cycle is being considered as a favorable candidate for the next generation nuclear reactors power conversion systems. Major benefits of the S-CO 2 Brayton cycle compared to other Brayton cycles are: (1) high thermal efficiency in relatively low turbine inlet temperature, (2) compactness of the turbomachineries and heat exchangers and (3) simpler cycle layout at an equivalent or superior thermal efficiency. However, these benefits can be still utilized even in the water-cooled reactor technologies under special circumstances. A small and medium size water-cooled nuclear reactor (SMR) has been gaining interest due to its wide range of application such as electricity generation, seawater desalination, district heating and propulsion. Another key advantage of a SMR is that it can be transported from one place to another mostly by maritime transport due to its small size, and sometimes even through a railway system. Therefore, the combination of a S-CO 2 Brayton cycle with a SMR can reinforce any advantages coming from its small size if the S-CO 2 Brayton cycle has much smaller size components, and simpler cycle layout compared to the currently considered steam Rankine cycle. In this paper, SMART (System-integrated Modular Advanced ReacTor), a 330 MW th integral reactor developed by KAERI (Korea Atomic Energy Institute) for multipurpose utilization, is considered as a potential candidate for applying the S-CO 2 Brayton cycle and advantages and disadvantages of the proposed system will be discussed in detail. In consideration of SMART condition, the turbine inlet pressure and size of heat exchangers are analyzed by using in-house code developed by KAIST–Khalifa University joint research team. According to the cycle evaluation, the maximum cycle efficiency

    Full Text Available The study intended to explore planning strategies gaps in ten-year perspective and medium-term development framework plans for agro-based industrial development in secondary cities of Sindh Province, Pakistan. Document review and key informant interviews survey techniques were used for data collection. A total of 30 interviews were conducted from agro-based officials. The SWOT analysis technique was applied for data analysis. The results revealed the weaknesses of high priority for textile and sugar industries, lack of planning strategies for agro-based development in secondary cities, dependency on federal government for development funds and absence of finances to implement plans. The threats were unavailability of strategic agro-based infrastructure facilities in secondary cities, centralized planning system, cross border threats such as the war in Afghanistan and migration of Afghan refugees, weak law and order situation and diversion of development budget for defense activities. The study suggests decentralization of powers and robust planning strategies in the development plans to strengthen secondary cities of Sindh Province economically.

    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

    Full text: Skeletal scintigraphy (SS) has been a workhorse in nuclear medicine departments, whether the department is in a developed country or in a developing country. It also plays an essential role in nuclear oncology in staging or diagnosing cancers or monitoring management of cancer patients. With the availability of improved imaging modalities like positron emission tomography, the role of skeletal scintigraphy is changing accordingly. This study was performed to evaluate the role of SS in nuclear oncology at a medium-sized (900-bed) university hospital in South Korea, by reviewing hospital cases along with the statistics of recently published papers in the journal of Clinical Nuclear Medicine. The hospital does not have a PET. The study period was three years (from 2000 to 2002). The SS is requested from many specialties for various reasons. Only cancer-related cases were selected. Using PubMed database, relevant articles in the Clinical Nuclear Medicine were assessed. To retrieve the articles, the keywords 'skeletal scintigraphy' and 'bone scan' were combined by using Boolean operation. There were a total of 9707 SS out of 16429 nuclear medicine imaging cases at the hospital during the study period. The hospital had 49% of SS contributed to cancer patients, while 52% percent of the SS in the CNM dealt with cancers. During the same period, articles regarding PET were 273 of which 171 were cancer-related PET studies (62%, more often than SS). 59% of the total nuclear medicine studies performed at the hospital were SS, whereas only 9% of the total articles were SS and 5% dealt with cancer-related cases. The cases of SS and cancer-related SS at the hospital increased during the period, whereas the articles in the CNM decreased. Analytic statistics were not considered necessary. In conclusion, there is an increasing demand of SS in nuclear oncology at a medium-sized hospital with non-availability of PET and the proportions of SS and cancer-related SS to the

    The spatial accuracy of top-down traffic emission inventory maps obtained with a simplified disaggregation method based on street density was assessed in seven mid-sized Chilean cities. Each top-down emission inventory map was compared against a reference, namely a more accurate bottom-up emission inventory map from the same study area. The comparison was carried out using a combination of numerical indicators and visual interpretation. Statistically significant differences were found between the seven cities with regard to the spatial accuracy of their top-down emission inventory maps. In compact cities with a simple street network and a single center, a good accuracy of the spatial distribution of emissions was achieved with correlation values>0.8 with respect to the bottom-up emission inventory of reference. In contrast, the simplified disaggregation method is not suitable for complex cities consisting of interconnected nuclei, resulting in correlation valuessituation to get an overview on the spatial distribution of the emissions generated by traffic activities.

    2011-01-01

    The study of particulate matter (PM) and nitrogen oxides emissions of diesel engines is nowadays a necessary step towards pollutant emission reduction. For a complete evaluation of PM emissions and its size characterization, one of the most challenging goals is to adapt the available techniques and the data acquisition procedures to the measurement and to propose a methodology for the interpretation of instantaneous particle size distributions (PSD) of combustion-derived particles produced by a vehicle during real driving conditions. In this work, PSD from the exhaust gas of a city bus operated in real driving conditions with passengers have been measured. For the study, the bus was equipped with a rotating disk diluter coupled to an air supply thermal conditioner (with an evaporating tube), the latter being connected to a TSI Engine Exhaust Particle Sizer spectrometer. The main objective of this work has been to propose an alternative procedure for evaluating the influence of several transient sequences on PSD emitted by a city bus used in real driving conditions with passengers. The transitions studied were those derived from the combination of four possible sequences or categories during real driving conditions: idle, acceleration, deceleration with fuel consumption and deceleration without fuel consumption. The analysis methodology used in this work proved to be a useful tool for a better understanding of the phenomena related to the determination of PSD emitted by a city bus during real driving conditions with passengers

    We present tomography of the circum-galactic metal distribution at redshift 1.7-4.5 derived from echellete spectroscopy of binary quasars. We find C IV systems at similar redshifts in paired sightlines more often than expected for sightline-independent redshifts. As the separation of the sightlines increases from 36 kpc to 907 kpc, the amplitude of this clustering decreases. At the largest separations, the C IV systems cluster similar to the Lyman-break galaxies studied by Adelberger et al. in 2005. The C IV systems are significantly less correlated than these galaxies, however, at separations less than R 1 ≅ 0.42 ± 0.15 h -1 comoving Mpc. Measured in real space, i.e., transverse to the sightlines, this length scale is significantly smaller than the break scale estimated previously from the line-of-sight correlation function in redshift space by Scannapieco et al. in 2006. Using a simple model, we interpret the new real-space measurement as an indication of the typical physical size of enriched regions. We adopt this size for enriched regions and fit the redshift-space distortion in the line-of-sight correlation function. The fitted velocity kick is consistent with the peculiar velocity of galaxies as determined by the underlying mass distribution and places an upper limit on the average outflow (or inflow) speed of metals. The implied timescale for dispersing metals is larger than the typical stellar ages of Lyman-break galaxies, and we argue that enrichment by galaxies at z ≥ 4.3 played a greater role in dispersing metals. To further constrain the growth of enriched regions, we discuss empirical constraints on the evolution of the C IV correlation function with cosmic time. This study demonstrates the potential of tomography for measuring the metal enrichment history of the circum-galactic medium.

    Work-related physical activity (PA) and work ability are of growing importance in modern working society. There is evidence for age- and job-related differences regarding PA and work ability. This study analyses work ability and work-related PA of employees in a medium-sized business regarding age and occupation. The total sample consists of 148 employees (116 men-78.38% of the sample-and 32 women, accounting for 21.62%; mean age: 40.85 ± 10.07 years). 100 subjects (67.57%) are white-collar workers (WC), and 48 (32.43%) are blue-collar workers (BC). Work ability is measured using the work ability index, and physical activity is obtained via the Global Physical Activity Questionnaire. Work ability shows significant differences regarding occupation (p = 0.001) but not regarding age. Further, significant differences are found for work-related PA concerning occupation (p Work ability is rated as good, yet, a special focus should lie on the promotion during early and late working life. Also, there is still a lack of evidence on the level of work-related PA. Considering work-related PA could add to meeting current activity recommendations.

    Advanced therapy medicinal products (ATMPs) are gene therapy, cell therapy, and tissue engineered products. To gain access to the market within the European Union, ATMPs must be authorized by the European Commission (EC). Especially for small and medium-sized enterprises (SMEs), the European centralized procedure of marketing authorization that is conducted by the European Medicines Agency (EMA) constitutes a major challenge, because SMEs often have little experience with regulatory procedures and many have limited financial possibilities. To tackle these challenges, a certification procedure exclusively for SMEs and their ATMP development was introduced by the EC. Independently from a marketing authorization application, development and/or production processes can be certified. An issued certificate demonstrates that the respective process meets the current regulatory and scientific requirements of the EMA, representing a valuable milestone for putative investors and licensees. This article highlights the background, the detailed procedure, the minimum requirements, as well as the costs of certification, while giving further noteworthy guidance for interested parties.

  2. An Influence of Strategic Awareness on Management Control: Evidence from Polish Micro, Small and Medium-sized Enterprises

    Full Text Available Purpose: The paper investigates whether employees’ strategic awareness influences the shape of management control systems (MCSs in Polish micro, small and medium-sized enterprises (mSMEs. Methodology: The study is based on data obtained from 223 companies between November 2010 and January 2012. The quantitative analysis used a set of variables which depicted MCSs: ‘goalsetting process’, ‘control framework’ and ‘organisation of control’. Strategic awareness was considered an independent variable. Findings: The results showed positive correlations between strategic awareness and considered variables. Regression models developed by the authors proved statistically valid. The study evidences, that increasing employees’ strategic awareness stimulates their participation in goal-setting, contributes to the development of more comprehensive MCSs, or may even imply formalisation of management control. Research limitations: The study does not include an analysis of the extent to which employees find MCSs useful in their work. This will be considered in future research. Another possible extension of the project is to identify factors which enable the capturing of the dynamic character of MCSs and their changes over time. Practical implications: The knowledge of MCSs does not explain whether or not the strategic orientation of a company stimulates a need for MCS. Such knowledge may be important to managers who have to face Polish employees’ general aversion to control. Originality: The study contributes to the limited body of knowledge in a scope of relations between employees’ strategic awareness and control mechanisms in Polish mSMEs.

    Objectives To assess the effectiveness of a comprehensive workplace stress management program consisting of participatory action-oriented training (PAOT) and individual management. Methods A comprehensive workplace stress management program was conducted in a medium-sized enterprise. The baseline survey was conducted in September 2011, using the Korean Occupational Stress Scale (KOSS) and Worker’s Stress Response Inventory (WSRI). After implementing both organizational and individual level interventions, the follow up evaluation was conducted in November 2011. Results Most of the workers participated in the organizational level PAOT and made Team-based improvement plans. Based on the stress survey, 24 workers were interviewed by a researcher. After the organizational and individual level interventions, there was a reduction of several adverse psychosocial factors and stress responses. In the case of blue-collar workers, psychosocial factors such as the physical environment, job demands, organizational system, lack of rewards, and occupational climate were significantly improved; in the case of white-collar workers, the occupational climate was improved. Conclusions In light of these results, we concluded that the comprehensive stress management program was effective in reducing work-related stress in a short-term period. A persistent long-term follow up is necessary to determine whether the observed effects are maintained over time. Both team-based improvement activities and individual interviews have to be sustainable and complementary to each other under the long-term plan. PMID:24524591

    A Study has been launched and supported by the Commission of the European Communities to assess the potential market of small and medium size nuclear reactors through EC Countries and to identify those factors which may play a dominant role in this respect. In its first phase, the Study addresses to modular high-temperature gas-cooled reactors that would be installed to produce low-temperature heat and power. Federal Republic of Germany, Italy and France are the countries for which the investigation has been either completed or is under way. The time span of interest is up to the year 2020. Referring to this horizon an appraisal has been made of the number of nuclear units which could come on line to cope with energy demand and their timing. Through the Study a distinction is made between technical potential, economic potential, and effective market potential. It is understood indeed that both economic competitiveness towards other energy sources and institutional or organizational factors may restrict the market which could be covered by this class of nuclear reactors.

    Full Text Available Small- and medium-sized enterprises (SMEs are the important driving forces for the growth of China’s economy. However, financing difficulty has always been the important problem besetting the development of SMEs for a long time. In particular, in recent years, US subprime crisis in 2008 caused a heavy blow to the development of some externally oriented SMEs. Thus, how to effectively overcome financing predicament for the SMEs is crucial for Chinese government. In this paper, based on microdata from China Industrial Enterprise Database, propensity score matching (PSM method is adopted to conduct empirical analysis about the treatment effects of indirect financing level of SMEs under different systems. Empirical results reveal that state-owned enterprises enjoy indirect financing advantages compared with other enterprises and there is certain ownership discrimination against foreign-funded enterprises and private enterprises. In particular, the indirect financing rate of state-owned enterprises is 1.4% higher than that of other enterprises, and the indirect financing rate of foreign-funded enterprises is 6% lower than that of other enterprises; private enterprises are advantageous in indirect financing compared with other enterprises; however, indirect financing rate of private enterprises is 1.8% lower than that of state-owned enterprises, which also reveals ownership discrimination to certain extent.

    Following a recent trend of scientific studies on artwork, we study here the thermodynamics of a jetting thermometer made of ceramic, related to the Chinese tea culture. The thermometer represents a boy who "urinates" shortly after hot water is poured onto his head. Long jetting distance indicates if the water temperature is hot enough to brew tea. Here, a thermofluid model describes the jetting phenomenon of that pee-pee boy. The study demonstrates how thermal expansion of an interior air pocket causes jetting. The validity of assumptions underlying the Hagen-Poiseuille flow is discussed for urethra of finite length. A thermodynamic potential is shown to define maximum jetting velocity. Seven optimization criteria to maximize jetting distance are provided, including two dimensionless numbers. The dimensionless numbers are obtained by comparing the time scales of the internal pressure buildup due to heating, with that of pressure relief due to jetting. Optimization results show that longer jets are produced by large individuals, with low body mass index, with a boyhood of medium size inclined at an angle π/4. Analogies are drawn with pissing contests among humans and lobsters. The study ends by noting similitudes of working principle between that politically incorrect thermometer and Galileo Galilei's thermoscope.

    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.

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

    This extended abstract intends to share the authors experience on the modelling of atmospheric pollutant dispersal and on the importance of building downwash considerations when assessing the need to heighten stacks of small and medium sized industrial enterprises (SME's). In order to understand the reasons that make industrial companies, especially SME's, consider stack heightening, in section 2 the existing Portuguese legislation on air quality and the stack heightening rules are briefly commented. New legislation that ought to appear soon (new Portuguese Air Act) is also commented and compared critically with the existing one. Then, section 3 characterizes Portuguese industry in terms of the ambient quality problems related to stack height. The adequacy of the stack heightening legislation to the particularities of the Portuguese case is discussed. In section 4 the authors experience in the specific study of stack heightening is presented. The methodology considered in these studies is discussed and compared with the application of existing and soon to appear legislation on stack height calculation. Finally, section 5 presents the conclusions and the need for an increased awareness on the pollutant dispersal problem is discussed. (orig.)

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

    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.

    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.

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

    The most important point of decommissioning nuclear facilities and nuclear power plants is to spend less money and do this process safely. In order to perform a better decommissioning nuclear facilities and nuclear power plants, a data base of radioactive waste from decontamination and decommissioning of nuclear facilities should be constructed. This data base is described herein, from the radioactive nuclide to the shape of component of nuclear facilities, and representative results of the status and analysis are presented. With the increase in number of nuclear facilities at the end of their useful life, the demand of decommissioning technologies will continue to grow for years to come. This analysis of medium-and large-sized radioactive metal wastes and 3D visualization technology of the radioactive metal wastes using the 3D-SCAN are planned to be used for constructing data bases. The data bases are expected to be used on development of the basic technologies for decommissioning nuclear facilities 4 session.

    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.

  18. The possible ways to IFRS (International Financial Reporting Standards for SME (Small and Medium sized Entities development

    Full Text Available The most business entities in Europe are small or medium-sized enterprises (SME, which have a legal obligation to prepare financial statements in accordance with a set of accounting principles accepted in their country. Those statements are available to creditors, suppliers, and national governments but they could be badly understandable to creditors, suppliers and subjects in other countries. This is a great obstacle of their activities in the EU internal market. The existence of 27 different national accounting systems in the EU can be held for the most important obstacle.There are many ways how to develop compatible accounting standards for SMEs but the most significant activity in this field is the research project of IASB (International Accounting Standards Board. IASB has developed IFRS (International Financial Reporting Standards. Even though IFRS are suitable for all enterprises, their application in case of SMEs would be very expensive and could significantly increase compliance costs of taxation. This development has not been finished yet and there are still some problems which need to be solved before the introduction of accounting standards to the public. The research has shown that IFRS for SMEs should be used mainly by the entities which do not have public accountability – i.e. that its equities are not publicly traded and do not hold assets in a fiduciary capacity for a broad group of outsiders. This paper discusses those IFRS modifications, which should be done in case of SMEs.

    Nowadays more than 20 million small and medium-sized enterprises (SMEs) are located in the European Union (EU): they are a key driver for economic growth, innovation, employment and social integration. The first step towards better industrial energy and environmental performance is the acknowledgement of the savings potential that can be realized by the company ownership and management board. Following this goal, the CEEM (Central Environmental and Energy Management) project provided to about 500 Central Europe SMEs of 5 countries (Austria, the Czech Republic, Hungary, Italy and Slovenia) a user friendly and free of charge web tool called 3EMT (Eco Energy Efficiency Management Tool). Through a questionnaire the 3EMT analyzes and sums up eco-energy patterns, helps to self-assess the company environmental performance, benchmarks a company with other Central Europe’s enterprises, delivers a customized Assessment Report, suggests further services and facilities. In this paper, the large 3EMT database is analyzed, and statistics focused on SMEs eco-energy performance and future & innovation perspectives are presented and discussed. Furthermore, key challenges and key intervention points were defined by local stakeholders (policy makers, Energy Service Companies, SMEs representatives, researchers), this paper summarizes the main policy outcomes. - Highlights: • Evaluation of Central Europe SME performance in energy efficiency and sustainability. • Extension of SME statistics at European and national level. • Identification of key challenges and key interventions for new industrial policies.

    Full Text Available In order to determine the organizational-economic and accounting aspects of franchising in the context of volatility of the macro-economic situation and the scarcity of entrepreneurs’ own funds, the current status of the franchising market in Ukraine, its economic essence and its role have been determined; the kinds of franchising that are known in world business practices have been provided; the types of distribution contracts that are close to the meaning of franchising have been defined; the legislative basis for franchising in Ukraine has been presented; the binding terms of a commercial concession contract as a legislated analogy of franchising in Ukraine have been determined; the features of reflection of the legality of franchising in accounting of both franchiser and franchisee have been provided. The objective advantages of franchising for both the large enterprises and the start-up entrepreneurs have been determined. On the basis of the legal nature of franchising relations in the accounting accounting, its reflection is close in the meaning to intangible assets. Implementation of franchising potential as a strategic tool for the development of small and medium-sized businesses requires the improvement of its legislative framework in the part of enhancing the responsibility of the parties.
