    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

    2014-08-01

    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.

  4. Managerial competencies among first-line newsroom managers at small to medium-sized mainstream media enterprises in South Africa

    2014-06-01

    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.

    Full Text Available Loxodonta africana (African Elephant are running out of living space so the protection of what space they have is essential. Existing areas of suitable elephant habitat need to be protected not only from human development but from the elephants themselves. As most elephant populations in South Africa are enclosed and multiplying, there is some increasing cause for concern as the damage caused will escalate and could reach unsustainable proportions. This study examined the utilization of satellite images for the detection of elephant induced ecosystem modification. A pilot study was conducted on four medium sized Game Reserves (each ±30 000 ha in South Africa. The aim was to ascertain the feasibility of using image analysis as instrument by which Game Reserve managers could assess biodiversity richness, habitat loss, and population-habitat viability. NDVI as indicator of primary production in vegetation is one of the instruments used to evaluate whether the carrying capacity for elephants of each Game Reserve has been reached and to compare the current biomass with those of previous years. The study also looked at the use of the woody canopy cover as target for change detection analysis. Spectral characteristics of specific trees species which are known for being preferred by elephants were used to conduct a temporal analysis on satellite images starting from the period when the elephants were re-introduced into each Game Reserve, thus attempting to identify possible impact on the biodiversity of the respective Game Reserves. Images from satellites such as Landsat, SPOT, Quickbird and SumbandilaSAT provided the needed data and maps.

    2011-03-01

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

  9. A perspective on open innovation in small- and medium-sized enterprises in South Africa, and design requirements for an open innovation approach

    Directory of Open Access Journals (Sweden)

    Krause, Willie

    2015-05-01

    Full Text Available This paper provides key results from an exploratory research study aimed at understanding the current landscape in small- and medium-sized enterprises (SMEs in South Africa with regard to their appetite for, and use of, open innovation. The survey, which was conducted within a contained group of SMEs that belong to business network groups on LinkedIn, explored the current use and perception of open innovation. It was found that collaboration is the approach most preferred by the SMEs surveyed, with customers and suppliers as their preferred innovation partners. Based on the findings of the survey, this paper proposes 25 design requirements, grouped into five functional categories, for an open innovation approach. The design requirements have been developed as a primer to a more complete open innovation approach for SMEs.

  10. The role of HIV/AIDS committees in effective workplace governance of HIV/AIDS in South African small and medium-sized enterprises (SMEs).

    2008-04-01

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

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

    Dongen, W. van [NedWind bv, Rhenen (Netherlands)

    1996-12-31

    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.

    2016-01-01

    The Cherenkov Telescope Array (CTA) is the planned next-generation instrument for ground-based gamma-ray astronomy, covering a photon energy range of ~20 GeV to above 100 TeV. CTA will consist of the order of 100 telescopes of three sizes, installed at two sites in the Northern and Southern Hemisphere. This contribution deals with the 12 meter Medium Size Telescopes (MST) having a single mirror (modified Davies-Cotton, DC) design. In the baseline design of the CTA arrays, 25 MSTs in the South and 15 MSTs in the North provide the necessary sensitivity for CTA in the core energy range of 100 GeV to 10 TeV. DC-MSTs will be equipped with photomultiplier (PMT)-based cameras. Two options are available for these focal plane instruments, that will be provided by the FlashCam and the NectarCAM sub-consortia. In this contribution, a short introduction to the projects and their status is given.

    Marfan syndrome is a relatively common connective tissue disorder that causes skin, ocular, skeletal, and cardiovascular abnormalities. High morbidity and mortality occur with aortic aneurysm and dissection. Other large-artery aneurysms, including carotid, subclavian, and iliac artery aneurysms, have also been associated with Marfan syndrome. It is not clear whether small- to medium-sized artery aneurysms are associated with Marfan syndrome. This report describes 4 patients with Marfan syndrome who have associated small- to medium-sized artery aneurysms with several complications. Additional investigations are needed to determine whether Marfan syndrome can cause small- to medium-sized artery aneurysms and how patients with these aneurysms should be treated.

    The Cherenkov Telescope Array (CTA) is the future instrument in ground-based gamma-ray astronomy in the energy range from 20 GeV to 300 TeV. Its sensitivity will surpass that of current generation experiments by a factor $\\sim$10, facilitated by telescopes of three sizes. The performance in the core energy regime will be dominated by Medium Size Telescopes (MST) with a reflector of 12 m diameter. A full-size mechanical prototype of the telescope structure has been constructed in Berlin. The performance of the prototype is being evaluated and optimisations, among others, facilitating the assembly procedure and mass production possibilities are being implemented. We present the current status of the developments from prototyping towards pre-production telescopes, which will be deployed at the final site.

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)

    2006-08-01

    The dipole polarizabilities of two families of low-lying structures, cage, and space filling, of the medium-sized AuN (N=32,38,44,50,56) clusters are studied using gradient-corrected density functional theory and finite field method. Both dipole moments and polarizabilities exhibit clear shape-dependent features and the cage structures have systematically smaller dipole moments and larger polarizabilities than the space-filling isomers. The mean polarizability per atom increases with cluster size for the cage structures, but it decreases slowly and tends to approach a constant for the space-filling structures. A linearly correlation between polarizability and cluster volume is noted, complying with the jellium model prediction for spherical metal clusters. The electronic effects including HOMO-LUMO gap and ionization energy on polarizabilities are also explored. The geometric effects play a dominant role on the determination of the polarizability of the cluster over the electronic effects.

    1989-05-24

    Results from these medium-sized rock heat source systems show that more functional trouble and inferior performance than expected are obtained if the borehole system is not adapted to the temperature demands of the heat pump cold transfer fluid. The design of the evaporator causes the evaporation temperature to become to low when the cold transfer fluid temperature reaches its lowest level for the year in two of the three plants studied. The third plant presents no functional trouble despite being operated at the same lowest cold transfer fluid temperature during the first years of operation. An analysis of complementary addition of boreholes in one of the plants with functional trouble reveals that the solution may be interesting if the heat pumps has to be capacity controlled for long periods during the heating season. In that plant the space for additional boreholes is limited, why the cost of this measure might be higher than the estimated SEK 240 per meter borehole. The computer code SBMA shows good agreement with measured weekly notations of the cold transfer fluid temperature during the first years of operation. The long-term temperature reduction caused by interaction between the closely located boreholes cannot be verified from only three years of operation. This fact gives cause for a follow-up of a number of medium-sized rock heat source systems for some additional years. 13 illus., 16 tabs. (author).

Buscando avaliar a situação de violência em uma cidade de médio porte, realizou-se um estudo transversal, de base populacional, investigando a prevalência de vitimização por violência urbana para furtos, roubos, agressões e furto/roubo à residência nos últimos cinco anos e 12 meses; e o perfil das vítimas e a prevalência de notificação à polícia. Foi construído um escore a fim de medir a vitimização por pelo menos um dos tipos de violência em cada período. Na análise bruta, a associação entre a vitimização por cada tipo de violência e as variáveis independentes foi investigada através do teste de Wald para heterogeneidade e para tendência linear, quando aplicável. A Regressão de Poisson foi utilizada na análise multivariável. Foram entrevistados 2.912 indivíduos (idade > 20 anos, sendo que 16,6% destes sofreram violência no último ano e 28% nos últimos cinco anos. As maiores prevalências de vitimização foram de furto/roubo à residência (9,7% e furto (6,0%. As principais vítimas de violência urbana foram homens e jovens. Mais da metade dos vitimizados não notificou a ocorrência por não confiar na polícia. Os achados confirmam a importância de pesquisas de vitimização além das metrópoles. As discussões sobre o tema mostram a necessidade de incrementar, executar ou criar políticas públicas de segurança e saúde em distintos contextos nacionais, sem desconsiderar cidades do interior.Urban violence affects individuals' lives, and therefore it is a complex problem of public health and security. To evaluate the occurrence of violence in a medium size city, a population-based cross-sectional study was carried out to investigate: prevalence of urban violence victimization (theft, robbery, aggression, and burglary in the period of five years and twelve months before the interview

    1998-01-01

    We present ground-state configurations and photoabsorption spectra of Na-7+, Na-27+ and Na-41+. For the first time, both the ionic structure and the photoabsorption spectra of medium-size sodium clusters beyond Na-20 have been calculated self-consistently with a non-spherical treatment of the valence electrons in density functional theory. We use a local pseudopotential that has been adjusted to experimental bulk properties and the atomic 3s level of sodium. Our studies have shown that both the ionic structure of the ground state and the positions of the plasmon resonances depend sensitively on the pseudopotential used in the calculation, which stresses the importance of its consistent use in both steps.

    Full Text Available This study aims to examine the role of entrepreneurial orientation (entrepreneurship orientation in innovation level among Small and Medium Size Enterprises (SMEs. A questionnaire survey was conducted among 137 firms in the Podlaskie Region. Three hypotheses related to entrepreneurial orientation and innovativeness level were examined by Structural Equation Modeling (SEM. The relation between two constructs of entrepreneurial orientation and innovativeness, that is proactiveness and risk taking were analyzed. The research results show that proactiveness has a significant positive total effect on improving innovativeness. The findings suggest, in contrast to the strategic orientation literature, that risk taking deters enterprises from organizational innovation. The results confirmed the significantly higher impact of the risk taking as an intermediate variable on the innovation through the mediator of proactivity. This work examines the relations between entrepreneurial orientation and innovativeness, thus contributes to the strategic orientation literature.

    Full Text Available The design, testing and realisation aspects during the development of a medium size aerostat envelope in the present work. The payload capacity of this aerostat is 300 kg at 1 km above mean sea level. The aerostat envelope is the aerodynamically shaped fabric enclosure part of the aerostat which generally uses helium for lifting useful payloads to a specified height. The envelope volume estimation technique is discussed which provides the basis for sizing. The design, material selection, testing and realisation aspects of this aerostat envelope are also discussed. The empirical formulas and finite element analysis are used to estimate the aerodynamic, structural and other design related parameters of the aerostat. Equilibrium studies are then explained for balancing forces and moments in static conditions. The tether profile estimation technique is discussed to estimate blow by distance and tether length. A comparison of estimated and measured performance parameters during trials has also been discussed.Defence Science Journal, Vol. 66, No. 2, March 2016, pp.93-99, DOI: http://dx.doi.org/10.14429/dsj.66.9291

    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.

    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.

    In this paper we give a summarized description of the HEAHP/J3 project, currently running under the support of the European Commission. In the frame of this project, a medium size reversible air to water heat pump for use with propane (R290) and appropriate for south European countries - in which refrigeration is a strong demand - is currently being developed by the partners. The starting point is a 20 kW, R22, commercial heat pump from CIATESA, a major Spanish heat pump manufacturer, which will be adapted and optimized for the use of propane as refrigerant. Computer simulations are under development aiming to identify the improvements and/or modifications needed in the components to ensure safe use and high efficiency, in terms of COP, of the heat pump. The scope of these models is to assist the optimization and design of the different elements of the heat pump. To aid the adjustment of these models while generating a large database covering the behavior of propane as a refrigerant, individualized characterization experiments of all pump components will be performed. Both aspects, modeling and measurements, are issued to converge in the reduction of size of all components resulting from the use of efficient extended surfaces in the heat exchangers and (for a given refrigeration or heat capacity) in the improvement of overall efficiency through the appropriate selection or adaptation, as far as possible, of the compressor.

    As produce consumption has increased, so have foodborne disease outbreaks associated with fresh produce. Little research has addressed food safety practices used on small to medium-sized farms selling locally or in farmers markets. This study evaluated current food safety practices used by farmers on small to medium-sized farms and managers of farmers markets in Georgia, Virginia, and South Carolina based on responses to surveys. Surveys were developed, pretested, and revised before implementation with target audiences and were implemented via mail and the Web to maximize participation, with reminders sent to nonrespondents. Data were collected from 226 farmers and 45 market managers. Frequencies and percentages were calculated for all response variables. Responses from farmers indicated that more than 56% of them use manures. Of those who use manures, 34% use raw or mixtures of raw and composted manure, and over 26% wait fewer than 90 days between application of raw manure and harvest. Over 27% use water sources that have not been tested for safety for irrigation, and 16% use such water sources for washing produce. Over 43% do not sanitize surfaces that touch produce at the farm. Only 33% of farmers always clean transport containers between uses. Responses from market managers indicated that over 42% have no food safety standards in place for the market. Only 2 to 11% ask farmers specific questions about conditions on the farm that could affect product safety. Less than 25% of managers sanitize market surfaces. Only 11% always clean market containers between uses. Over 75% of markets offer no sanitation training to workers or vendors. While farmers and market managers are using many good practices, the results indicate that some practices being used may put consumers at risk of foodborne illness. Consequently, there is a need for training for both farmers and market managers.

    In the fall of 1992, the TAC Team was presented with a Request for Proposal (PFP) for a mid-size (250-350 passenger) commercial transport. The aircraft was to be extremely competitive in the areas of passenger comfort, performance, and economic aspects. Through the use of supercritical airfoils, a technologically advanced Very High By-pass Ratio (VHBR) turbofan engine, a low overall drag configuration, a comparable interior layout, and mild use of composites, the JB-300 offers an economically viable choice to the airlines. The cents per passenger mile of the JB-300 is 1.76, which is considerably lower than current aircraft in the same range. Overall, the JB-300 is a technologically advanced aircraft, which will meet the demands of the 21st century.

    Significant changes have occurred over the past two decades in the volume, intensity, direction, and modalities of internal migration in Mexico. Interstate migration, for example, has increased greatly. The number of persons living in a state different from that of their birth grew from 7.5 million in 1970 to 15.4 million in 1990, equivalent to 14.5% and 18.1% of the population, respectively. The growing volume and intensity of interstate migration have been accompanied by a declining rate of migration to Mexico City and to a lesser extent Guadalajara and Monterrey. Cities of intermediate size, defined as 100,000 to one million inhabitants, have multiplied since 1970 and a few have achieved great economic and demographic dynamism. In 1970, 16.6% of the population or 33.6% of the urban population lived in 37 intermediate cities, while by 1990 nearly 23.7% of the population and 39.0% of the urban population lived in 56 intermediate sized cities. Census and survey data confirm the power of attraction of a group of intermediate cities, but also reveal a complex array of situations. 24 of the 56 intermediate cities had populations of 100,000-250,000, and 21 had populations of 250,000-500,000. Most intermediate cities are located in the Northwest, Center-North, or Gulf regions. Some states have a number of intermediate cities and some have only one that concentrates most of the urban population. 26 of the 56 had growth rates over the two decades of over 4% annually and 20 had rates varying from 3% to 4%. 1990 census data show that 35% or more of the population were in-migrants in five cities: Tijuana, Mexicali and Ensenada in the Northwest, Cuernavaca in the Center-North, and Cancun in the Yucatan peninsula. Between 20% and 34% of the population were in-migrants in 14 intermediate cities. Cancun and Tijuana had the highest proportions of recent migrants. The volume of net migration of most states generally reflected that of their intermediate cities. The economic crisis

    Full Text Available Abstract Background In South Africa, respiratory protective equipment is often the primary control method used to protect workers. This preliminary study investigated how well a common disposable P2 respirator fitted persons with a range of facial dimensions. Methods Quantitative respirator fit tests were performed on 29 volunteers from different racial, gender and face size groups. Two facial dimensions width (bizygomatic and length (menton-sellion were measured for all participants. Results In this study 13.8% of the participants demonstrated a successful fit with the medium sized mask. These included participants from three different racial and both gender groups. The large percentage of failed fit tests (86% indicates that reliance on off-the-shelf respirators could be problematic in South Africa. Conclusions The limitations of this preliminary study notwithstanding, respirator fit appear to be associated with individual facial characteristics and are not specific to racial/ethnic or gender characteristics.

    Rodent preference for scatter-hoarding large seeds has been widely considered to favor the evolution of large seeds. Previous studies supporting this conclusion were primarily based on observations at earlier stages of seed dispersal, or on a limited sample of successfully established seedlings. Because seed dispersal comprises multiple dispersal stages, we hypothesized that differential foraging preference on seed size by animal dispersers at different dispersal stages would ultimately result in medium-sized seeds having the highest dispersal success rates. In this study, by tracking a large number of seeds for 5 yr, we investigated the effects of seed size on seed fates from seed removal to seedling establishment of a dominant plant Pittosporopsis kerrii (Icacinaceae) dispersed by scatter-hoarding rodents in tropical forest in southwest China. We found that small seeds had a lower survival rate at the early dispersal stage where more small seeds were predated at seed stations and after removal; large seeds had a lower survival rate at the late dispersal stage, more large seeds were recovered, predated after being cached, or larder-hoarded. Medium-sized seeds experienced the highest dispersal success. Our study suggests that differential foraging preferences by scatter-hoarding rodents at different stages of seed dispersal could result in conflicting selective pressures on seed size and higher dispersal success of medium-sized seeds.

    Full Text Available Sector of small and medium-sized enterprises is regarded as the backbone of the economy and a driving force of innovation, employment and social integration. Development of the sector of small and medium-sized enterprises in the Czech Republic has a substantial impact on economic and social development of the country and its various regions. This article deals with the human resources management in small and medium-sized enterprises, because it is more than obvious recently that the prosperity of the organization is depended on human resources and management of them can determine not only whether the organizations succeed, but whether it will be able to survive in turbulent conditions in the present world. The main aim of this paper is to analytical describe the monitoring the process of human resources management in selected categories of enterprises by business activity and number of employees including statistical analysis of causal effects. Further to analytical describe the evaluation the process of human resources management and indicators of this process, which are monitored by small and medium-sized enterprises. To achieve this aim were used selected primary data collected in the project GAJU 068/2010/S titled “Process management and its possible implementation in small and medium-sized enterprises”.

    Full Text Available This study examines the awareness, the implementation status, and the results from implementing Lean among small- and medium-sized enterprises (SMEs in two segments of Virginia’s manufacturing industry. One hundred and eighty responses from a census mail survey (population size 1033 were analyzed and the results confirm previous research that smaller enterprises in these industries are marginally aware of Lean and its potential benefits. Smaller enterprises also have implemented Lean to a lesser degree than have medium or large enterprises. Also, fewer respondents working in small enterprises reported improvements in ‘lead-time,’ ‘on-time delivery,’ ‘inventory turnover,’ ‘cost per unit,’ and ‘sales per employee’ due to the implementation of Lean than respondents from medium and large enterprises. Small enterprises also indicated a lower need for Lean implementation support from third parties than did medium or large enterprises.

    Lunar pyroclastic deposits (LPDs) are low albedo features that mantle underlying terrain (Gaddis et al. 1985). They are high priority targets for science and exploration as they are believed to originate from and therefore reflect the composition of the deep lunar interior (NRC, 2011). They are also the best potential resource of oxygen out of any Apollo samples (Allen et al. 1996). Historically, LPDs have been divided into regional versus local categories (Gaddis et al. 2003). The large (>1000 km2 area) regional deposits are deeply sourced (>400 km deep) and result from fire fountaining. Small (medium-sized deposits to characterize this potential new class of deposits and understand the magnitude of variations in inferred FeO among pyroclastic deposits. We use the method of Greenhagen et al. (2010) to calculate the wavelength of the Christiansen Feature (CF) from Lunar Reconnaissance Orbiter Diviner Lunar Radiometer instrument thermal-infrared observations for four medium-sized deposits. From the CF values, we estimate each deposit's FeO abundance using the method of Allen et al. (2012). The four LPDs that we examined (Oppenheimer South, Beer, Cleomedes, and J. Herschel) all have average CF values from 8.22-8.28 microns, corresponding to FeO abundances of approx. 10-15 wt.%. All of these values are within the range and uncertainties of FeO abundances measured in Apollo samples. As previously identified, the Oppenheimer South deposit exhibits an area of enhanced CF values (8.49 microns) that, if the methods of Allen et al. (2012) can be extrapolated, correspond to a highest observed approx. 30 wt.% FeO. Moon Mineralogy Mapper near-infrared spectra indicate that this area is glass-rich as opposed to olivine-rich. While we are still investigating the nature of the high CF wavelength in Oppenheimer South, spatially-resolved observations there and (to a smaller degree) in our other study sites, shows that FeO wt.% can vary within LPDs. Thus, obtaining only the average

    Full Text Available In rural areas, we are now dealing with a surplus of labour in agriculture and lack of jobs for the population without land. The decreasing role of agriculture and the benefits of agricultural production as a primary source of income of the rural population makes it necessary to supplement income from other activities. Making activities in the sector of small and medium-sized enterprises can significantly be replenished. Small and medium-sized enterprises can be regarded as a manifestation of entrepreneurship in rural areas. The aim of the study is to identify the role and importance of small and medium-sized enterprises in rural activation. In this study, the statistical material available from GUS contained in the publications concerning rural areas in Poland and literature.

    Although the astronomy community is witnessing an era of large telescopes, smaller and medium sized telescopes still maintain their utility being larger in numbers. In order to obtain better scientific outputs it is necessary to incorporate modern and advanced technologies to the back-end instruments and to their interfaces with the telescopes through various control processes. However often tight financial constraints on the smaller and medium size observatories limit the scope and utility of these systems. Most of the time for every new development on the telescope the back-end control systems are required to be built from scratch leading to high costs and efforts. Therefore a simple, low cost control system for small and medium size observatory needs to be developed to minimize the cost and efforts while going for the expansion of the observatory. Here we report on the development of a modern, multipurpose instrument control system UNICS (Unified Instrument Control System) to integrate the controls of vari...

  15. Factors preceding CRM readiness in small- and medium-sized tourism enterprises

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

    Giancarlo Gomes

    Full Text Available Abstract Although the relation between the organizational learning capability, organizational innovation and performance has often been studied, there is little empirical evidence to support this perspective in small and medium-sized enterprises. This study aims at analyzing the influence of organizational learning capability in innovative performance and organizational performance of small and medium-sized enterprises. The research was conducted under the quantitative approach, descriptive and causal, and cross-sectional survey. The sample was composed of 92 enterprises in the textile industry. The data were analyzed through the technique of Structural Equation Modeling. The results show that the organizational learning capability influences the innovative performance of small and medium-sized enterprises, however, the influence of the learning capability in organizational performance was not significant. The study provides evidence for these relations and shows that they are significant and positive in the context of small and medium-sized textile enterprises, context in which the empirical literature is particularly scarce. For future research it is suggested to evaluate contingency factors for innovative and organizational performance. Other studies could analyze the differences in innovation between manufacturing and service sector.

    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.

    There has been no study about treatment guidelines for arthroscopic repair according to the size of bony Bankart lesions of less than 25% of the glenoid width. To evaluate the results of arthroscopic repair for bony Bankart lesions managed with different repair techniques based on their size. Case series; Level of evidence, 4. Between March 2005 and February 2009, 44 of 52 consecutive patients with bony Bankart lesions with a size of less than 25% of the entire glenoid were managed with an arthroscopic approach. Of those patients, 34 (77%) were available for outcome analysis at a minimum 24 months' follow-up (mean, 34 months; range, 24-60 months). The size of the fragment was measured by computed tomography (CT) and classified as small (lesions were classified as small (small group), and 18 were classified as medium (medium group). For small lesions, capsulolabral repair using suture anchors without excision of the bony fragment was performed. For medium lesions, anatomic reduction and fixation using suture anchors was performed, and the adequacy of reduction was assessed by CT postoperatively. The visual analog scale (VAS) for pain score and modified Rowe score for bony Bankart repair were compared and the postoperative recurrence rate investigated. One patient from the small group (6.3%) and 1 patient without anatomic reduction of the bony fragment in the medium group (5.6%) experienced traumatic redislocations. The mean VAS score improved from 1.7 preoperatively to 0.5 at final follow-up, and the mean Rowe score improved from 59 to 91 (both P Bankart lesions, restoration of capsulolabral soft tissue tension alone may be enough, whereas in medium lesions, the osseous architecture of the glenoid should be reconstructed for more functional improvement and less pain.

    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

    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.

    Full Text Available Angel investors are very important for small and medium sized enterprises because they provide more than money. They are hands-on investors and contribute their skills, expertise, knowledge and contacts in the businesses they invest in. They are wealthy persons with great business experience. They are willing to invest and offer their wealth and knowledge to owners of small and medium sized enterprises and to entrepreneurs to start or develop their businesses. One of the attributes of angel investors is that they like to remain anonymus. Due to this attribute, a lot of ideas can not be accomplished. To eliminate this, many countries establish angel investor syndicates (groups and networks. These syndicates (groups and networks facilitate the process of matching entrepreneurs and angel investors.

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

    Full Text Available This paper builds a sustainable financing credit rating index system for small- and medium-sized enterprises in China from the perspective of sustainability. Then, a quantitative model for credit rating evaluation based on our index system is proposed by using fuzzy analytic hierarchy process (FAHP, which has the advantage of considering both quantitative and qualitative factors. Our numerical example shows that the index system is effective and practical. Our system improves the existing credit rating system to a certain extent. The evaluation method proposed can play an important guiding role for China's small- and medium-sized enterprises in the current transformation age. In particular, interested stakeholders can use this model to evaluate the investment risk of companies, especially with a focus on sustainability.

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.

    The prevalence of workplace health promotion in small and medium-sized enterprises (SME) in Germany as well as age management were investigated. Representative data were collected by computer assisted telephone interviews in 1 441 SME (1-250 employees) in 7 regions of Germany. One-third of the SME have a system of health promotion. Disability management is known only in one third of the enterprises, another third of them knew the legal obligations. About half of the enterprises have a system to collect data about health-related absenteeism in business. Effects caused by the demographic change in Germany are feared by nearly 50% of the enterprises, but only 20% have taken action against it. The implementation of work health promotion is higher in enterprises with more employees. The study shows that workplace health promotion (WHP) in German small and medium-sized enterprises is not yet installed to a wide extent. The smaller the enterprises the less WHP is found. The results are verified by similar studies. Small and medium-sized enterprises have a need for consultation in cases of illness or health prevention. But there is not yet an organised structure available for getting advice. The study is the basis for a national project "Gesunde Arbeit", which will establish these consulting structures. © Georg Thieme Verlag KG Stuttgart · New York.

    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.

    The CO2 laser surface alloying technique was used to form wear resistance layers on medium carbon steel with a kind of spherical WC powder. The effects of WC particle size on the abrasive wear resistance were thoroughly investigated. The results indicate that the laser alloyed layer is characterized by dendritic primary phase and ledeburite microstructure, consisting of austenite, martensite and carbides of Fe3W3C, W2C and WC. The laser surface alloying with WC powder could improve the abrasive wear resistance of the medium carbon steel by over 63%. The factors such as the hardness, the amount and the distribution of WC particle determined the laser alloyed samples' wear resistance, and the laser alloyed sample with WC powder of 88-100 μm diameter presented the best wear resistance in this study. Furthermore, the wear resistance mechanisms of the laser alloyed layers were also explored.

    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.

    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

    Herein, we describe the synthesis of molecular scaffolds consisting of medium-sized fused heterocycles using amino acids, which are some of the most useful building blocks used by nature as well as chemists to create structural diversity. The acyclic precursors were assembled by using traditional Merrifield solid-phase peptide synthesis, and cyclization was carried out through acid-mediated tandem endocyclic N-acyliminium ion formation, followed by nucleophilic addition with internal nucleophiles. The synthesis of molecular scaffolds consisting of seven-, eight-, and nine-membered rings proceeded with full stereocontrol of the newly generated stereogenic center in most cases.

    Tiziani, D; Oakes, L; Schwanke, U

    2016-01-01

    An important aspect of the calibration of the Cherenkov Telescope Array is the pointing, which enables an exact alignment of each telescope and therefore allows to transform a position in the sky to a point in the plane of the Cherenkov camera and vice versa. The favoured approach for the pointing calibration of the medium size telescopes (MST) is the installation of an optical CCD-camera in the dish of the telescope that captures the position of the Cherenkov camera and of the stars in the night sky simultaneously during data taking. The adaption of this approach is presented in this proceeding.

    Full Text Available Competitiveness of national economies depends in great part on technological development and implementation of knowledge from science and research in practice. The phenomenon of cooperation represents an integral part of these processes. While its bounded forms, like mergers and acquisitions are relatively embedded in the Czech Republic, the advantages of less formal partnerships have been gradually discovered just recently.In the paper we focus on a special type of cooperation called networks. In order to get an initial overview, we introduce some of the basic definitions, as the specialized literature lacks single explanation and categorization. Within the framework of our research we have focused on such purposeful connections of small and medium enterprises that bring benefits for both sides and lead to the growth of competitiveness. The aim of the article is to investigate the prerequisites of interfirm network operation in the South Moravian Region.The first part of the paper introduces network cooperation, especially the motives standing behind network set-up, the typology of networks and the role of networks at regional level. Then we briefly describe the South Moravian region, where our investigation has been made. We focus especially on the demonstration of the most powerful and perspective economic branches in which we consider networks very important. This base is further extended by the information received in the South Moravian Innovation Centre, an interest association of legal persons having experience especially in research institution – company cooperation. The operation of a partnership network is analyzed on the case of DC Concept, a. s., a company from Brno producing and developing information system for middle and large companies. We introduce the six types of their partners, the system how the network works and the motives lying behind.The paper is based on the information gained during the pre-research which falls

    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

    The structures and melting properties of the medium-sized silicon nanoclusters have been comparatively studied using the molecular dynamics method. Structural and thermodynamic parameters are used to characterize the melting properties of the clusters. The size dependence of the melting temperature of silicon nanoclusters is determined using the computation results. Different from the homogeneous melting of bulk silicon, melting of silicon nanoparticles proceeds over a finite temperature range due to surface effects, which shows the heterogeneous melting of nanoclusters. We found that the melting starts at the cluster surface and progressively shifts into the core region. This study provides a fundamental perspective on the melting behaviors of semiconductor silicon nanoclusters at the atomistic level.

    Full Text Available It is a common fact, that innovations are the necessary prerequisite of economic development. With regard to the gradual globalization of the world economy, it is obvious that the strategic objectives of every country are directed to own economic wealth which is lead especially by the small and medium-sized enterprises. Due to the fact that these business entities are creating the most of economic growth of every country, the necessity of research, support and development of their innovation potential is obvious. The last and also the least that one could starve for is the building up the barriers to innovativeness of domestic companies, and to decrease competitiveness of the country.In the paper, the authors are focused on the determination of barriers to innovation potential of small and medium-sized enterprises. For this reason, the secondary research of recent studies on innovation barriers has been elaborated. Subsequently, the primary research has been realized on the statistical sample of 173 SMEs. Based on the data analyses, the authors have proved four statistical interactions between innovation potential and factors which stand as barriers to innovation potential development. This paper is based on the confrontation of outcomes of primary research with the secondary research on world-wide perceived barriers to innovations. Data obtained from the primary research had mostly the qualitative and categorical character. Due to this fact, especially Chi-square Test, normalized Pearson coefficient of contingence and Chuprov’s coefficient have been applied.

  5. Determinants of Supply and Demand for Trade Credit by Micro, Small and Medium-Sized Enterprises

    Directory of Open Access Journals (Sweden)

    Claudinê Jordão de Carvalho

    2015-08-01

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

    2015-06-01

    Full Text Available The promotion of domestic consumption in China will gradually ramp up the small and medium-sized port container industry, and this will require greater port efficiency and an updated development strategy. The aim of this paper is to evaluate operational and productivity efficiency change in 21 coastal small and medium sized-port container terminals in China. The first step was carried out using data envelopment analysis (DEA and the Malmquist productivity index (MPI, and the factors affecting productivity efficiency change were then estimated and quantified using Tobit regression. The empirical results indicate that the most efficient terminals are the Rizhao and Lianyungang port terminals. Furthermore, the terminals that hold a share of more than 50% of Chinese state-owned shipping line show the highest increase in productivity efficiency change. Lastly, the results indicate manpower structure; Chinese state-owned shipping line shareholding; registered capital; and shipping routes have positive effect and the factor, number of terminal operators, have a negative correlation.

    Fast neutron detectors with a sub-centimetric space resolution are required in order to qualify neutron beams in applications related to magnetically-controlled nuclear fusion plasmas and to spallation sources. Based on the results obtained with small area prototypes, the first medium-size (20 x 35.2 cm2 active area) nGEM detector has been realized for both the CNESM diagnostic system of the SPIDER NBI prototype for ITER and as a beam monitor for fast neutrons beam lines at spallation sources, too. The nGEM is a Triple GEM gaseous detector equipped with polyethylene layers used to convert fast neutrons into recoil protons through the elastic scattering process. This paper describes the performance of the medium-size nGEM detector tested at the VESUVIO beam line of the ISIS spallation source. Being this detector the actual largest area fast neutron detector based on the GEM technology, particular attention was paid in the study of detector response in different points over the active area. Measurements of GEM counting rate (both as a function of VGEM and of time) and of the capability of the detector to reconstruct the beam in different positions are presented. This detector serves as a basis for the realization of an even larger area detector that will be used in the MITICA NBI prototype for ITER that represents the evolution of SPIDER.

    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.

    We demonstrate a miniaturized acoustofluidic device composed of a pair of slanted interdigitated transducers (SIDTs) and a polydimethylsiloxane microchannel for achieving size-selective separation and exchange of medium around polystyrene particles in a continuous, label-free, and contactless fashion. The SIDTs, deposited parallel to each other, produce tunable traveling surface acoustic waves (TSAWs) at desired locations, which, in turn, yield an anechoic corner inside the microchannel that is used to selectively deflect particles of choice from their streamlines. The TSAWs with frequency fR originating from the right SIDT and propagating left toward the microchannel normal to the fluid flow direction, laterally deflect larger particles with diameter d1 from the hydrodynamically focused sample fluid that carries other particles as well with diameters d2 and d3, such that d1 > d2 > d3. The deflected particles (d1) are pushed into the top-left corner of the microchannel. Downstream, the TSAWs with frequency fL, such that fL > fR, disseminating from the left SIDT, deflect the medium-sized particles (d2) rightward, leaving behind the larger particles (d1) unaffected in the top-left anechoic corner and the smaller particles (d3) in the middle of the microchannel, thereby achieving particle separation. A particle not present in the anechoic corner could be deflected rightward to realize twice the medium exchange. In this work, the three-way separation of polystyrene particles with diameters of 3, 4.2, and 5 μm and 3, 5, and 7 μm is achieved using two separate devices. Moreover, these devices are used to demonstrate multimedium exchange around polystyrene particles ∼5 μm and 7 μm in diameter.

    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.

    2011-08-01

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

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

    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.

    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.

    2011-06-01

    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.

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

    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.

    2017-03-01

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

    2017-04-01

    In this paper, we study the longitudinal linear and nonlinear free vibration response of a single walled carbon nanotube (CNT) embedded in an elastic medium subjected to different boundary conditions. This formulation is based on a large deformation analysis in which the linear and nonlinear von Kármán strains and their gradient are included in the expression of the strain energy and the velocity and its gradient are taken into account in the expression of the kinetic energy. Therefore, static and kinetic length scales associated with both energies are introduced to model size effects. The governing motion equation along with the boundary conditions are derived using Hamilton's principle. Closed-form solutions for the linear free vibration problem of the embedded CNT rod are first obtained. Then, the nonlinear free vibration response is investigated for various values of length scales using the method of multiple scales.

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.

    , we propose that Human Resource Management (HRM) may provide a means by which SMEs can increase their capacity for deriving value from innovation networks, which is a rather unexplored area of the literature. To begin, we present a brief review of the relevant literature on networks, and innovation......Collaboration in innovation networks is particularly important for small and medium enterprises (SMEs) to remain competitive in a rapidly changing environment. Collaboration may however be particularly challenging for SMEs, due to their size and their inherent shortage of resources. In this paper...... in networks in particular, and HRM. We then analyze current models and empirical studies aimed at identifying specific HRM practices that support innovation and evaluate their applicability to SMEs in innovation networks. We argue that the HRM implications for network collaboration of SMEs are considerable...

    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.

    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.

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

    Full Text Available 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.

    2016-04-01

    This paper presents a small multi-model ensemble study of coupling two different ERA-Interim driven RCMs (WRF and COSMO-CLM) using different grid sizes (0.44°, 0.11°, 0.03°) with a hydrological model for representing floods in small to medium sized catchments in South-eastern Austria. The aim is to evaluate the benefit of grid size reduction and in particular, the added value of convection-permitting simulations with 0.03° (~ 3 km) resolution. The hydrological model is a spatially distributed model (1 km² grid), which was previously developed for operational flood forecasting and calibrated against data of more than 20 stream gauges with corresponding catchment sizes between 30 and 1000 km². The hindcast simulations (1989-2010) are evaluated in terms of accurately representing flood frequency, seasonality, as well as other flood event characteristics, such as weather type, antecedent soil moisture, etc. The results show, that for small catchments (frequency and seasonality is represented well in all catchments. In the larger catchments a resolution of 0.11° (~ 12.5 km) already yields statistically satisfying results. Also, due to the short response times in the small sub-catchments a time step of 1 hour is required. However, in all setups a bias still exists in precipitation and temperature, which sometimes leads to unrealistic hydrological conditions. Ongoing work comprises the test a of novel statistical error correction method, which is expected to improve results particularly for higher quantiles. Also, a future run ("time-slice" experiment) is planned with the coupled model setup using the RCP8.5 emission scenario, the GCM of the Max-Planck-Institute Hamburg (MPI-ESM-LR), dynamically downscaled to 3 km by COSMO-CLM, and the novel error correction method. The study is funded by the Austrian Klima- und Energiefonds through the Austrian Climate Research Programme (ACRP) by means of the project CHC-FloodS (id KR13AC6K11102).

    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.

    CTA (Cherenkov Telescope Array) is one of the largest ground-based astronomy projects being pursued and will be the largest facility for ground-based γ-ray observations ever built. CTA will consist of two arrays (one in the Northern hemisphere and one in the Southern hemisphere) composed of telescopes of several sizes. A prototype for the Medium Size Telescope (MST) of a diameter of 12 m will be installed in Berlin by the end of 2012. This MST prototype will be composed of the mechanical structure, drive system and mirror facets mounted with powered actuators to enable active control. Five Charge-Coupled Device (CCD) cameras and a weather station will allow the measurement of the performance of the instrument. The Atacama Large Millimeter/submillimeter Array (ALMA) Common Software (ACS) distributed control framework is currently being considered by the CTA consortium to serve as the array control middleware. In order to evaluate the ACS software, it has been decided to implement an ACS-based readout and control system for the MST prototype. The design of the control software is following the concepts and tools under evaluation within the CTA consortium, like the use of a Unified Modeling Language (UML) based code generation framework for ACS component modeling, and the use of OPen Connectivity-Unified Architecture (OPC UA) for hardware access. In this contribution, the progress in the implementation of the control system for this CTA prototype telescope is described.

    Full Text Available Non-metallic inclusions found in steel can affect its performance characteristics. Their impact depends not only on their quality, but also, among others, on their size and distribution in the steel volume. The literature mainly describes the results of tests on hard steels, particularly bearing steels. The amount of non-metallic inclusions found in steel with a medium carbon content melted under industrial conditions is rarely presented in the literature. The tested steel was melted in an electric arc furnace and then desulfurized and argonrefined. Seven typical industrial melts were analyzed, in which ca. 75% secondary raw materials were used. The amount of non-metallic inclusions was determined by optical and extraction methods. The test results are presented using stereometric indices. Inclusions are characterized by measuring ranges. The chemical composition of steel and contents of inclusions in every melts are presented. The results are shown in graphical form. The presented analysis of the tests results on the amount and size of non-metallic inclusions can be used to assess them operational strength and durability of steel melted and refined in the desulfurization and argon refining processes.

    Small- and medium-sized ventral hernias including umbilical hernias can be repaired using prosthetic patches placed in the peritoneum. However, bowel-associated complications secondary to intraperitoneally placed hernia patches have been reported. Herein, we report the outcome of small and medium umbilical hernia closure with prosthetic hernia patches in the preperitoneal space. Prospectively collected data of patients undergoing repair of small- and medium-sized umbilical hernias with the proceed ventral patch in a primary care hospital in Germany was retrospectively analyzed. A total of 39 cases, including 11 female and 28 male patients, were managed with prosthetic patches in the preperitoneal position. Small-sized patches were implantated in 16 cases, whereas medium-sized patches were used in 23 cases. The median duration of surgery was 40 minutes. The median length of hospital stay was four days. Four minor complications were recorded (10.3%) and the rate of recurrence was 2.6 per cent within a follow-up period of up to 30 months. Small and medium size umbilical hernias can be effectively closed with prosthetic patches placed in the preperitoneal space without risk of serious bowel associated complications.

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

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

    Full Text Available The nucleus accumbens is a limbic nucleus, representing part of the striatum body, and together with the caudate nucleus and putamen, it lies on the septum. The aim of this study was to examine morphological sexual dimorphism in spine density and also to undertake an immunohistochemical study of expression for estrogen and progesterone receptors in the medium-sized neurons in the nucleus accumbens. The research was conducted on twenty human brains of persons of both sexes, between the age of 20-75 years. The Golgi method was applied to determine the types and subtypes of neurons, morphologies of soma, dendrites and axons, as well as the relations between the cells and glial elements. The following were quantitatively examined: the maximum diameter of the neurons, the minimal diameter of the neurons, and the total length of the dendrites. The expression of receptors for estrogen and progesterone, their distribution and intensity were defined immunohistochemically. The parameters of the bodies of neurons in the shell and core of the nucleus accumbens were studied in both men and women. No statistically significant differences were found. Examination of the spine density showed statistical significance in terms of a higher density of spines in women. Immunohistochemically, in the female brain estrogen expression is diffusely spread in a large number of neurons; it is extra nuclear, of granular appearance and high intensity. In the male brain, expression of estrogen is visible and distributed over about one half of different types of neurons; it is extra nuclear, of granular appearance, mostly of middle and low staining intensity. Expression of progesterone in the female brain was very discreet and on a very small number of neurons; it was extra nuclear and with a weak staining intensity. Expression of progesterone in the male brain was distributed on a small number of neurons. It had a granular appearance, it was extra nuclear, with a very low

    Full Text Available Urban climate is the result of both atmospheric and geographic factors affecting a region, as well as the morphology, structures and human activities in a city. Urban vegetation in particular affects this climate at a local scale and provides many other social, economic and ecological benefits. Thus, it is important to explore the effects of different green areas used for urban and periurban agriculture and forestry activities (UPAF on daily atmospheric temperature and the required degrees of cooling or refrigerating temperature. Comfort temperatures were defined using a range 18-24°C and analyzed using actual measured as well as forecasted temperatures using a future scenario. Actual temperatures were recorded from September 2013 to August 2014 using digital sensors across eight sites in Rosario, Argentina: three in the central core with no vegetation, one in the central core with street trees, one in an urban agriculture site, one in a public park and two in periurban agricultural areas. Results show that air temperature in the central core with no vegetation were higher than those in other sites with vegetation during day and night, with the exception of the temperatures measured at the central core site with street trees. Findings also show that temperature effects in urban agricultural gardens of approximately 0.2 ha were similar to those of gardens and public parks 2-3 ha in size. Three UPAF types were classified according to cooling degree days, which decreased in order from (1 central core with no trees; (2 central core with street trees and public parks; and (3 urban and periurban agriculture areas. Conversely, the opposite trends for heating degree days were found. Results from this study can be used for integrating UPAF measures into climate change mitigation and urban planning policies in medium-sized cities in the developing world.

    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.

    Porter, R. W.

    1982-09-01

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

    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 ABSTRACT The study aimed to evaluate the water distribution from a medium-size sprinkler working in solid set sprinkler systems. Water distribution radial curves from the sprinkler operating under four nozzle diameter combinations (4.0 x 4.6; 5.0 x 4.6; 6.2 x 4.6 and; 7.1 x 4.6 mm and four working pressures (196; 245; 294 and 343 kPa were evaluated on the sprinkler test bench of the State University of Maringá, in Cidade Gaúcha, Paraná, Brazil. The sixteen water distribution curves were normalized and subjected to clustering analysis (K-Means algorithm, identifying the occurrence of normalized distribution curves with three different geometric shapes. A computer algorithm, in Visual Basic for Applications in Excel spreadsheet, was developed to simulate the water application uniformity (Christiansen's Coefficient - CU from the sprinklers working with rectangular and triangular layouts in solid set sprinkler systems. For the three geometric shapes of the normalized water distribution curves, digital simulation results of water distribution uniformity for the sprinklers on mainline and lateral line spaced between 10 to 100% of wetted diameter indicated that sprinkler spacings around 50% of the wetted diameter provide acceptable CU values.

    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.

    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 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.

    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 physiologically active substances in apple vinegar have not yet been chemically characterized. We studied the biological functions of apple vinegar produced from crushed apples, and found that the constituent neutral medium-sized alpha-glycan (NMalphaG) acts as an antitumor agent against experimental mouse tumors. NMalphaG is a homoglycan composed of glucose having a molecular weight of about 10,000 and a branched structure bearing alpha (1-4,6) linkages. In this study, we clarified the origin of NMalphaG in apple vinegar by examination of its content in alcohol and acetic acid fermentation products sequentially. We found that NMalphaG appeared in acetic acid fermentation, but not in alcohol fermentation. Furthermore we investigated NMalphaG origin using acetic acid fermentation from alcohol fortifiied apple without alcohol fermentation and from raw material with varying amounts of pomace. The results indicate that NMalphaG originated in the apple fruit body and that its production requires both fermentation processes.

    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.

    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.

    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.

  16. Signaling from the cytoplasm to the nucleus in striatal medium-sized spiny neurons

    2011-07-01

    Full Text Available Striatal medium-sized spiny neurons (MSNs receive massive glutamate inputs from the cerebral cortex and thalamus and are a major target of dopamine projections. Interaction between glutamate and dopamine signaling is crucial for the control of movement and reward-driven learning, and its alterations are implicated in several neuropsychiatric disorders including Parkinson’s disease and drug addiction. Long-lasting forms of synaptic plasticity are thought to depend on transcription of gene products that alter the structure and/or function of neurons. Although multiple signal transduction pathways regulate transcription, little is known about signal transmission between the cytoplasm and the nucleus of striatal neurons and its regulation. Here we review the current knowledge of the signaling cascades that target the nucleus of MSNs, most of which are activated by cAMP and/or Ca2+. We outline the mechanisms by which signals originating at the plasma membrane and amplified in the cytoplasm are relayed to the nucleus, through the regulation of several protein kinases and phosphatases and transport through the nuclear pore. We also summarize the identified mechanisms of transcription regulation and chromatin remodeling in MSNs that appear to be important for behavioral adaptations, and discuss their relationships with epigenetic regulation.

  17. Fully Flexible Docking of Medium Sized Ligand Libraries with RosettaLigand.

    Directory of Open Access Journals (Sweden)

    Samuel DeLuca

    Full Text Available RosettaLigand has been successfully used to predict binding poses in protein-small molecule complexes. However, the RosettaLigand docking protocol is comparatively slow in identifying an initial starting pose for the small molecule (ligand making it unfeasible for use in virtual High Throughput Screening (vHTS. To overcome this limitation, we developed a new sampling approach for placing the ligand in the protein binding site during the initial 'low-resolution' docking step. It combines the translational and rotational adjustments to the ligand pose in a single transformation step. The new algorithm is both more accurate and more time-efficient. The docking success rate is improved by 10-15% in a benchmark set of 43 protein/ligand complexes, reducing the number of models that typically need to be generated from 1000 to 150. The average time to generate a model is reduced from 50 seconds to 10 seconds. As a result we observe an effective 30-fold speed increase, making RosettaLigand appropriate for docking medium sized ligand libraries. We demonstrate that this improved initial placement of the ligand is critical for successful prediction of an accurate binding position in the 'high-resolution' full atom refinement step.

  18. ADVANTAGES OF CROWDFUNDING AS AN ALTERNATIVE SOURCE OF FINANCING OF SMALL AND MEDIUM-SIZED ENTERPRISES

    Directory of Open Access Journals (Sweden)

    Zorica Golić

    2014-08-01

    Full Text Available The lack of funding, and limited access to it are the basic problems faced by small and medium-sized enterprises (SMEs. Given the great role and importance of SMEs in every national economy, any progress in solving these problems in terms of creating and finding alternative sources of funding should attract great attention in both professional and scientific and the wider socio-political communities. Crowdfunding is an innovative and relatively new concept that connects entrepreneurs and investors through the Internet. This method allows the entrepreneurs to collect funds through the Internet by "open invitation" to finance their projects/ventures and thus raise the necessary funds by relatively small contributions of a relatively large number of investors. As such, crowdfunding is a fast-growing model increasingly debated of in academic circles and the European institutions. This paper will consider crowdfunding as an alternative means of financing SMEs and try to give different aspects of crowdfunding - and explain how it works, what are the advantages of using it for SMEs and thus expand the knowledge on the topic.

    Full Text Available The flexibility coefficient is popularly used to implement the macroevaluation of shape, safety, and economy for arch dam. However, the description of flexibility coefficient has not drawn a widely consensus all the time. Based on a large number of relative instance data, the relationship between influencing factor and flexibility coefficient is analyzed by means of partial least-squares regression. The partial least-squares regression equation of flexibility coefficient in certain height range between 30 m and 70 m is established. Regressive precision and equation stability are further investigated. The analytical model of statistical flexibility coefficient is provided. The flexibility coefficient criterion is determined preliminarily to evaluate the shape of low- and medium-sized arch dam. A case study is finally presented to illustrate the potential engineering application. According to the analysis result of partial least-squares regression, it is shown that there is strong relationship between flexibility coefficient and average thickness of dam, thickness-height ratio of crown cantilever, arc height ratio, and dam height, but the effect of rise-span ratio is little relatively. The considered factors in the proposed model are more comprehensive, and the applied scope is clearer than that of the traditional calculation methods. It is more suitable for the analogy analysis in engineering design and the safety evaluation for arch dam.

    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.

    This study aimed to estimate the prevalence of gastrointestinal nematodes and the intensity of infection in grazing dairy cattle from small and medium-sized farms in southern Poland. The level of antibodies against Ostertagia ostertagi in the bulk tank milk (BTM) from the animals was also assessed. Rectal fecal samples collected from 361 cows on 20 farms were examined using Willis-Schlaaf flotation and the McMaster method. BTM samples were tested for the presence of O. ostertagi antibodies using ELISA. Multiplex PCR was used to identify the third-stage larvae (L3) of gastrointestinal nematodes derived from the culture of pooled fecal samples from sampled farms. Gastrointestinal nematode eggs were found in the samples from 18 of the 20 herds with a prevalence range from 20.4 to 94.5%. The average number of eggs excreted in the feces of the herds was 200 eggs per gram (EPG). Antibodies to O. ostertagi were found in 20 of the examined herds (100%), of which 6 had optical density ratios (ODR) greater than 0.5. PCR results showed the presence of three nematode species: Ostertagia ostertagi, Cooperia oncophora and Oesophagostomum radiatum.

    Full Text Available The study aims to contribute to the literature by empirically examining the relationship between small and medium sized enterprises’ (SMEs mission statements and their performance in sustainable strategy formulation. Although it seems that there is a relatively vast amount of research with regard to mission statements of companies, very few studies have focused on the relationship between mission statements and performance. When these few studies are taken into consideration, it is difficult to reach any overall conclusion since their findings are mixed and inconclusive. To achieve this aim, 3034 SMEs operating in organized industrial zones in Turkey were examined via a survey approach. In order to investigate the relationships among the variables, nine categories of mission statements as independent variables and four performance indicators (financial, market, production, and overall as dependent variables were analyzed through logistic regression. This study identified three mission components, (1 survival, growth, and profit; (2 philosophy and values; and (3 public image, as the common independent variables in explaining the performance of SMEs. Survival, growth, and profit is the most frequently observed mission component regardless of the subsector differentiation in the entire sample, which reflects the significance of business sustainability for SMEs in the Turkish manufacturing context. Besides, among all performance indicators, SMEs’ market performance was found to be the lowest when compared to other performance indicators (financial, production, overall. Although the firms were placed in different manufacturing subsectors, similar mission statements were highlighted so that the discourse similarity might be considered as evidence of isomorphism characteristics for SMEs.

    Pointing calibration is an offline correction applied in order to obtain the true pointing direction of a telescope. The Cherenkov Telescope Array (CTA) aims to have the precision to determine the position of point-like as well as slightly extended sources, with the goal of systematic errors less than 7 arc seconds in space angle. This poster describes the pointing calibration concept being developed for the CTA Medium Size Telescope (MST) prototype at Berlin-Adlershof, showing test results and preliminary measurements. The MST pointing calibration method uses two CCD cameras, mounted on the telescope dish, to determine the true pointing of the telescope. The "Lid CCD" is aligned to the optical axis of the telescope, calibrated with LEDs on the dummy gamma-camera lid; the "Sky CCD" is pre-aligned to the Lid CCD and the transformation between the Sky and Lid CCD camera fields of view is precisely modelled with images from special pointing runs which are also used to determine the pointing model.

    2013-12-01

    Full Text Available The activity of service companies is more complex today than before the use of Information and Communication Technology (ICT became widespread in business. Fewer service companies can be found on the market based solely on physical customer interaction; however, they have been replaced with standardized and automated services. This structural change can be observed particularly among Knowledge Intensive Business Services (KIBS companies where the use of ICT is not simply a market requirement, but a competition tool, as well. Without the application of any ICT instrument, a KIBS company could not meet market expectations, and furthermore, business developments are mainly ICT-based. On the other hand, companies need to develop their businesses more and more, as KIBS companies which are not able to differentiate themselves as trustworthy on the business services market will disappear. ‘Just another business service company’ cannot really sell today. This is applicable to a greater extent to Small and Medium Sized Enterprises (SME, where ICT has opened market opportunities that have never existed for them before. The aim of this paper is to highlight the new features of KIBS business activities in the SME sector and the related research questions.

    2013-09-01

    Full Text Available The AnnAGNPS model was used to estimate runoff, peak discharge and sediment yield at the event scale in the Carapelle watershed, a Mediterranean medium-size watershed (506 km2 located in Apulia, Southern Italy. The model was calibrated and validated using five years of runoff and sediment yield data measured at a monitoring station located at Ordona – Ponte dei Sauri Bridge. A total of 36 events was used to estimate the output of the model during the period 2007-2011, in comparison to the corresponding observations at the watershed outlet. The model performed well in predicting runoff, as was testified by the high values of the coefficients of efficiency and determination during the validation process. The peak flows predictions were satisfactory especially for the high flow events; the prediction capability of sediment yield was good, even if a slight over-estimation was observed. Finally, the model was used to evaluate the effectiveness of different Management practices (MPs on the watershed (converting wheat to forest, using vegetated streams, crop rotation corn/soybean, no tillage. While the maximum reduction in sediment yield was achieved converting wheat to forest, the best compromises between soil conservation and agriculture resulted to be crop rotations.

    1993-01-01

    The authors present a concept of continuously graded multilayer structures for medium-sized X-ray telescopes which is based on several material combinations. They show that the theoretical reflectivity characteristics of these structures make them very advantageous when applied to high energy X......-ray grazing incidence telescopes. They consider the performance of continuously graded Ni/C multilayers in a multi-focus, Kirkpatrick-Baez, geometry and show a significant improvement when compared to standard coatings of gold. For a total length of 3.3 m, a total aperture of 48 cm by 48 cm and 64 foci......, an effective area of 250 cm2 at 60 keV and a FWHM field of view of 6' is obtained. It is shown that a modular array of conical telescopes (conical approximation to a Wolter-I geometry), with the same length and aperture provides similar effective areas. Energy-dispersive X-ray reflectivity data (15-70 ke...

    2008-05-01

    This study reports the first assessment of organotin pollution in the Hérault watershed, a medium size Mediterranean basin. Organotin compounds were analyzed in surface waters, wells supplying drinking water and sewage treatment plants (STPs). In surface and ground waters, a background contamination by total organotin compounds has been identified in the range of 0.51 +/- 0.02-71 +/- 2 ng(Sn) L(-1), which is of the same order of magnitude as those observed in other European areas. Organotins were systematically present in STP influents and sludge. Total or partial elimination of organotin compounds from treated wastewater was observed. STP effluents appeared nevertheless to be a non-negligible source of contamination not only of rivers but also of aquifers tapped for drinking water supply. Tributyltin concentration was higher than the maximum allowable concentration proposed by the European Commission in some surface waters and wells supplying drinking water. This could compromise the water resource and have serious and irreversible consequences for the aquatic eco-system. As it was the case for the ban of antifouling paints, a regulatory regime in decreasing point-source emissions of these harmful compounds used in household products might be applied.

    1991-05-01

    Energy Analysis and Diagnostic Centers (EADCs) provided energy-conserving and cost saving assistance in 339 small and medium-size manufacturing plants nationwide during 1988-89. This report presents the results of what was recommended to those manufacturers, the record of what was implemented by them, and an analysis of the financial rewards gained by them. It also includes an accounting of the financial returns to the federal government, derived from taxes upon the cost savings, or incremental income, of the manufacturers who implement the EADCs` recommendations. EADCs collect implementation data within a year of the energy audit, and for these results that time period extended through 1990. The EADCs are located at accredited engineering departments of universities and staffed by faculty and students. At present there are 18 EADCs serving manufacturers in 37 states; of these, two were established as a result of the 1989 competition, and five more were chosen competitively in 1990. Most of the results in this report were generated by 11 EADCs (named in the Appendix); two others withdrew voluntarily after completing only 10 energy audits during 1988-89. Primary responsibility for selecting, training, evaluating, and managing the EADCs belongs to the Industrial Technology and Energy Management (ITEM) division of University City Science Center (UCSC). The Department of Energy`s Office of Industrial Technologies sponsors the EADC program through an agreement with UCSC.

    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.

    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 In this article innovative capability, i.e. the ability of new products and markets development, is analyzed and empirically tested. The results have proven that the companies with more developed innovative capabilities achieve higher performance levels, but that there is no difference in innovative capabilities between large and medium-sized companies. On the other hand, medium-sized companies have slightly higher levels of sales growth and increase in market share. Also, companies in foreign ownership are better at development of new products and new production methods, and they have higher levels of sales growth, market share and increase in market share.

    Immunosuppressive drugs and biological agents may represent a potential risk of lymphoma development in patients with rheumatoid arthritis. But most cases are diffuse, large B-cell lymphomas. Primary cutaneous CD4+ small/medium-sized pleomorphic T-cell lymphoma, a provisional entity in the 2005 WHO-EORTC classification of cutaneous lymphomas, is only described in a limited number of reports. To our knowledge, our case is a rare instance of primary cutaneous CD4+ small/medium-sized pleomorphic T-cell lymphoma, after associated treatment with methotrexate and etanercept, in a patient with moderate rheumatoid arthritis who had undergone an orchidectomy incorrectly.

    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.

    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)). The two spin component scaled (SCS) MP2 methods resulted in

    Full Text Available  This work studied the deterioration of commercial Frytol oil in controlled frying conditions using the anisidine index (AI as standard evaluation method. The effect of temperature and time was studied at 170°C for up to 10 hours and at 200°C for up to 6 hours in the presence of factors which speeded up oil deterioration: 1% and 8% water based on the mass of oil and non-lipid material, 1% and 6% based on the mass of oil. Air flow rate was kept constant at 25 L h-1. The relationship between AI, colour and viscosity was studied to evaluate the technical viability of measuring these variables as a function of time to be used as a method for rating oil deterioration by small and medium sized enterprises (SME. Oil deterioration was higher and faster at maximum study interval values for each experimental factor, although only the effect of temperature was significant (p2=0.558 and R2=0.526, respectively, colour depending on frying temperature. Viscosity measured at 30°C had the highest coefficient of determination (R2=0.809 and was independent of frying temperature. Viscosity is thus a variable which can be used for determining frying oil deterioration in SME as a consequence of a significant change from 10 cP to 45 cP which is closer to frying oil deterioration limit (AI 156. It can facilitate determination and lower associated costs, thereby improving product quality and customer confidence in them.

    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.

    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

    Asylum seekers constitute a particularly vulnerable group. Not only is their physical and mental health exposed to multiple stresses, but also their access to health care in Germany is legally restricted. Up to now, there is very limited scientific literature investigating the health-outcomes of asylum seekers in Germany. The aim of this study was to provide prevalence data on the morbidity and vaccination status of asylum seekers in a medium-sized German city. We used a structured questionnaire in a cross-sectional study on 214 adult asylum seekers (182 males, 24 females, 8 unknown) in Halle, Germany, 2015. The questionnaire inquired about the respondent's self-reported physical health and vaccination status and assessed their mental health using the Hopkins-Symptom-Checklist-25 and the Harvard Trauma Questionnaire. Pain (37.9 %) and psychological illness (depression: 54.7 %, anxiety disorder: 40.2 %; post-traumatic stress disorder: 18.2 %) were the most prevalent complaints. Among asylum seekers with psychological complaints, co-morbidity was high (64.2 % had more than one psychological disease). 5.6 % of the respondents mentioned suicidal thoughts. The prevalence of chronic diseases was low. We suggest interventions to improve asylum seekers' health on two levels: first, the obligatory initial medical examination after the refugees' arrival at the reception centre should be complemented with questions related to the vaccination status and the most common complaints including pain and psychological diseases. Second, medical infrastructure should be expanded to better serve the needs of culturally and linguistically diverse patient populations, so that those screened positive can be referred for early diagnosis and treatment.

    Full Text Available 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.

    At company level responsibility increases for the employment of workers with health-related problems or disabilities, but realisation in small and medium-sized enterprises (SME) is lacking. Therefore a model is developed based on theory and a survey. Minimum requirements for "betriebliches Eingliederungsmanagement" (integration management at company level) according to section 84 (2) SGB IX Book 9 of the German Social Code, the main products of the international movement "disability management", a description of roles for realisation and the main sources of employers' support are described. Although external supporting of SMEs is unquestioned, it is expensive and retards own initiative and own activity counting solely on this. Only by developing a minimum of SME's awareness, acceptance and competence, this will open up to (currently suboptimal) external support. Goal is identifying SME managers' attitudes, activities, proposals and expectations referring integration management at company level to derive concepts of SME's support. 13 interviews are analysed by qualitative content analysis identifying the following barriers: information deficit, absence of priority, limited possibilities for transitional work, cost, partially limited workers' self-responsibility, illness as a "tabes" subject. Possibilities overcoming these barriers are delineated. On that basis a model is presented: pragmatically for realisation, a company contact person with minimum competence, uniform external support, institutional partners' integration and quality assurance according to disability management. Interlocking SME world and social insurance world means first to support SME's awareness, acceptance and competence, second to create for SME a central contact in the "rehabilitation jungle" and third to develop SME-suitable premiums according to section 84 (3) SGB IX, Book 9 of the German social code.

    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.

    Whereas microbiological quality of drinking water in water distribution systems is routinely monitored for reasons of legal compliance, microbial numbers in tap water are grossly understudied. Motivated by gross differences in water from private households, we applied in this study flow cytometry as a rapid analytical method to quantify microbial concentrations in water sampled at diverse taps in a medium size research building receiving chlorinated water. Taps differed considerably in frequency of usage and were located in laboratories, bathrooms, and a coffee kitchen. Substantial differences were observed between taps with concentrations (per mL) in the range from 6.29 x 10(3) to 7.74 x 10(5) for total cells and from 1.66 x 10(3) to 4.31 x 10(5) for intact cells. The percentage of intact cells varied between 7% and 96%. Water from taps with very infrequent use showed the highest bacterial numbers and the highest proportions of intact cells. Stagnation tended to increase microbial numbers in water from those taps which were otherwise frequently used. Microbial numbers in other taps that were rarely opened were not affected by stagnation as their water is probably mostly stagnant. For cold water taps, microbial numbers and the percentage of intact cells tended to decline with flushing with the greatest decline for taps used least frequently whereas microbial concentrations in water from hot water taps tended to be somewhat more stable. We conclude that microbiological water quality is mainly determined by building-specific parameters. Tap water profiling can provide valuable insight into plumbing system hygiene and maintenance.

  5. Geological constraints of giant and medium-sized gas fields in Kuqa Depression

    Institute of Scientific and Technical Information of China (English)

    2002-01-01

    There is a gas-rich and well-charged petroleum system in the Kuqa Depression where Triassic and Jurassic source rocks play important roles. Distributed in an area of more than 10000 km2 and with a thickness of up to 1000 m, they are composed of dark mudstones, carbonaceous mudstones and coal seams containing 6%, 40% and 90% of TOC, respectively, and are mainly the humic organic matter. As high-quality regional cap rocks, the Neogene and Eogene gypsum rocks and gypseous mudstones matched well with the underlying Neogene and Cretaceous-Eogene sandstones. They have formed the most favorable reservoir-seal assemblages in the Kuqa Depression. Also the Jurassic sandstones and mudstones formed another favorable reservoir-seal assemblage. The traps are shaped late in the fold-thrust belt, mainly fixed in the Tertiary-Quaternary, where ten structure styles have been distinguished. These traps spread as a zone in N-S, are scattered like a segmental line in W-E and show tier-styled vertically. The best traps are gypsum-salt covered fault-bend anticlines related to the passive roof duplex. This petroleum system is characterized by late accumulation. In the early Himalayan Movement, mainly gas condensate and oil accumulated and were distributed in the outer circular region of the kitchen; whereas in the middle and late Himalayan the gas accumulations mainly formed and were distributed in the inner circular region near the kitchen. The overpressure of gas pools is common and is formed by seal capacity of thick gypsum layers, extensive tectonic compression and large uplift. The well-preserved anticline traps underlying the high-quality regional cap rocks of the Tertiary gypsum rocks and gypseous mudstones are the main targets for the discovery of giant and medium-sized gas fields. Above conclusions are important for the petroleum geology theory and the exploration of the fold-thrust belt in foreland basins in central and western China.

    Fragment-based quantum chemistry methods are either based on the many-body expansion or the inclusion-exclusion principle. To compare the applicability of these two categories of methods, we have systematically evaluated the performance of the generalized energy based fragmentation (GEBF) method (J. Phys. Chem. A, 2007, 111, 2193) and the electrostatically embedded many-body (EE-MB) method (J. Chem. Theory Comput., 2007, 3, 46) for medium-sized water clusters (H2O)n (n = 10, 20, 30). Our calculations demonstrate that the GEBF method provides uniformly accurate ground-state energies for 10 low-energy isomers of three water clusters under study at a series of theory levels, while the EE-MB method (with one water molecule as a fragment and without using the cutoff distance) shows a poor convergence for (H2O)20 and (H2O)30 when the basis set contains diffuse functions. Our analysis shows that the neglect of the basis set superposition error for each subsystem has little effect on the accuracy of the GEBF method, but leads to much less accurate results for the EE-MB method. The accuracy of the EE-MB method can be dramatically improved by using an appropriate cutoff distance and using two water molecules as a fragment. For (H2O)30, the average deviation of the EE-MB method truncated up to the three-body level calculated using this strategy (relative to the conventional energies) is about 0.003 hartree at the M06-2X/6-311++G** level, while the deviation of the GEBF method with a similar computational cost is less than 0.001 hartree. The GEBF method is demonstrated to be applicable for electronic structure calculations of water clusters at any basis set.

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

    Directory of Open Access Journals (Sweden)

    Christina Valeska Sager-Klauss

    2016-04-01

    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

  11. The Conduciveness of the South African Economic Environment and Small, Medium and Micro Enterprise Sustainability: A Literature Review

    Directory of Open Access Journals (Sweden)

    Juan-Pierré BRUWER

    2017-01-01

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

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

    Directory of Open Access Journals (Sweden)

    Meleancă Raluca-Cristina

    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

    2010-01-01

    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 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

  15. Improving HVAC operational efficiency in small-and medium-size commercial buildings

    Energy Technology Data Exchange (ETDEWEB)

    Kim, Woohyun; Katipamula, Srinivas; Lutes, Robert

    2017-08-01

    Small- and medium-size (<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 use 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 United States for many reasons, chief among them being 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, when an RTU goes through ON and OFF cycles too frequently. Excessive cycling can lead to excessive wear and to premature failure of the compressor or its components. Also, short cycling can result in a significantly decreased average efficiency (up to 10%), even if there are no physical failures in the equipment. 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 paper describes two algorithms for detecting the zone set point temperature and RTU cycling rate 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 field data from a number of RTUs from six buildings in different climate locations. Overall, the algorithms were successful in detecting the set points and ON

    Full Text Available Problem statement: The value and importance of knowledge, as seen by numerous organisations today, does without a doubt play a crucial role in the current ever-challenging and aggressive business environment. As a result, businesses that aspire to be labelled as being successful and competitive need to seek and find better ways to improve their firms’ performance. Hence, Knowledge Management (KM, which is viewed as a source of sustainable competitive advantage, has attracted the attention of various companies all over the business world, including Small and Medium-Size Enterprises (SMEs in Malaysia. With the realisation of KM, the systematic management of organisation knowledge - a strategic corporate asset not to be taken lightly; can thus be created, transferred, shared and, utilised, in pushing for greater organisational competitiveness, innovativeness and, productivity. This research examined the success factors that help to increase the business performance of SMEs in Malaysia. Besides, it also highlighted the importance and contribution of KM amongst SMEs. Therefore, the reason behind this study is to understand and recognised the acceptance of KM and therefore further classified the success factors that contributed to the business performance outcome amongst SMEs in Malaysia. With this, the success factors observed in this research; culture; leadership; employee participation; Information and Communications Technology (ICT; organisational structure; are thoroughly investigated to explore on whether these factors have an impact on knowledge creation; knowledge transfer; knowledge sharing and knowledge utilisation; of KM processes among SMEs in Malaysia. Approach: This study aids to determined and examined the success factors; culture; leadership; employee participation; Information and Communications Technology (ICT; organisational structure; of SMEs that further influences KM processes; knowledge creation, transfer, sharing, utilisation

    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

    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

    Full Text Available Approach: The amount of energy related costs as a portion of the total farm operating cost can be as high as 29% and the continuing increase of the real cost of energy related farm input has been one of the major factors impacting the cost of agricultural production. However, agricultural has the potential of replacing some of the purchased energy in the form of fossil fuels, commercial fertilizer and field production of animal feed with bioenergy and organic fertilizer from onsite renewable biomass such as animal manure in order to economically and environmentally sustain it. The aim of this study was to develop an innovative energy efficient pilot scale anaerobic digester composting facility. Methodology: A solid/liquid manure separator farm scale anaerobic digester and composting facility for a medium sized dairy farm were designed, constructed and tested. In order to make the anaerobic digestion economically viable under Canadian climatic conditions, the design, installation and operation of the system were based on advantages gained from the digester as a component of the total farm management system. In addition to the biogas production, benefits related to manure handling and storage, environmental quality improvement through odor control and water pollution reduction, fertilizer recovery and water recycling, were considered. Results: The layout of the farm was modified to provide solutions for four environmental problems related to: disposal of milkhouse wastes and overflow from the manure storage facility into the fire pond. The system possesses high energy conversion efficiency at relatively low capital cost and reduced labour requirement and has indirect energy ramifications through the production of organic fertilizer (compost to replace expensive and energy consuming commercial fertilizer as well as the production of bioenergy (biogas which will reduce the demand for energy. The overflow from the system (purified water can be

    The purpose of this report is to exemplify and clarify the need for ventilation in medium-sized and large boiler houses. We will furthermore present some recommendations, guidelines and advice for the design and construction of a boiler house ventilation system to the plant owners and suppliers of equipment. Boiler house ventilation can be performed in different ways using mechanical or natural ventilation. The solution to be chosen depends on the following factors: Working environment requirements and a necessity to control temperature and pressure in the boiler house; The design of the boiler plant and house; The need for combustion air; The investment expenditure as well as operation and maintenance costs. Mechanical ventilation should be chosen if the aim is a controllable 'climate'. The mechanical ventilation can be either centrally situated or distributed with many aggregates in the boiler house. Centrally situated ventilation equipment will give a higher accessibility and lower maintenance costs than a distributed ventilation system. If the boiler house is designed with natural ventilation the air and flue gas fans will be the only ones installed. In this case temperature and pressure inside the boiler house will be difficult to control. The design factor for the ventilation plant in a boiler house is in most cases the demand to cool the air inside the boiler house to approximately 45 deg C. This is the highest temperature allowed by the Occupational Safety and Health Act in a work environment where the boiler operator is working alone. The air flow which is required for the combustion is normally less than the air flow needed to cool the air in the boiler house. The supply air which is cooling the air inside the boiler house should be supplied on several different levels to attain an efficient cooling. If the combustion air is taken from the heated indoor air the boiler house will work as a heat reclaimer. The difference between outdoor and indoor

    Conclusions: Medium-sized hepatocellular carcinoma can be effectively ablated with monopolar radiofrequency ablation by either single-electrode overlapping ablation or a multiple-electrode switching system. Regarding mid-term treatment responses, both RFA approaches can achieve similar treatment effectiveness, local tumor progression rate, and survival probabilities. Multiple-electrode switching RFA can treat larger medium-sized HCC with comparable mid-term efficacy as smaller medium-sized HCC treated with single-electrode overlapping RFA.

    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.

    In archaeology, it is not always possible to identify bone fragments. A novel approach was chosen to assess the potential of histology as an identification tool. Instead of studying a few bones of different categories from many species, this study concentrated on the diaphyses of long bones in four species of comparable size which are relevant to archaeology; young humans, pigs, sheep and goats, to broaden the insight into variations in diaphyseal bone structure within and between these species. A general difference in the primary bone structure was found between children older than one year and the three medium-sized mammals, namely lamellar vs. fibro-lamellar primary bone. Although, the diaphyseal bone structure of children below the age of one year also showed (developing) fibro-lamellar bone, its composition was distinctive from the medium-sized mammals. A difference in the secondary bone structure was also observed. Connecting (Volkmann's) canals, giving the secondary bone a reticular aspect, were seen in the medium-sized mammals but not in the young human long bones. To confirm the validity and applicability of these observed histological differences, a blind test was conducted on 14 diaphyseal fragments of identified long bones from archaeological sites. The results were very promising. All the bone fragments were correctly attributed using the difference in primary bone structure, even when the bone was severely degraded.

    BACKGROUND: Abdominal aortic aneurysm (AAA) is thought to develop as a result of inflammatory processes in the aortic wall. In particular, mast cells are believed to play a central role. The AORTA trial was undertaken to investigate whether the mast cell inhibitor, pemirolast, could retard...... the growth of medium-sized AAAs. In preclinical and clinical trials, pemirolast has been shown to inhibit antigen-induced allergic reactions. METHODS: Inclusion criteria for the trial were patients with an AAA of 39-49 mm in diameter on ultrasound imaging. Among exclusion criteria were previous aortic....... There was no statistically significant difference in growth between patients receiving placebo and those in the three dose groups of pemirolast. Similarly, there were no differences in adverse events. CONCLUSION: Treatment with pemirolast did not retard the growth of medium-sized AAAs. REGISTRATION NUMBER: NCT01354184...

    Assessment of time and space relationships among magmatism, volcanism, and resurgence of medium-size calderas is a necessary tool to formulate a general model for their dynamics which also permits to forecast their evolution. To define a general hypothesis for the Campi Flegrei caldera, in a persistent state of unrest, the Ischia and Pantelleria medium-size resurgent structures, in variable stages of evolution, have been investigated. In particular some parameters such as the structural and volcanological evolution, with emphasis on resurgence dynamics and coeval volcanism, and the evolution, present state and role of the magmatic system in resurgence, have been defined. For the Campi Flegrei caldera, the data collected during unrest episodes have also been taken into account. This innovative approach adds a time-perspective on how resurgent calderas behave. The proposed general hypothesis will help in long- and short-term volcanic hazards assessment and will support Civil Defence Authorities in elaborating actions devoted to volcanic risk reduction.

    Rockfill dams are mostly constructed using blasted rockfill materials obtained by blasting rocks or al-luvial rockfill materials collected from the riverbeds. Behaviors of rockfill materials and their charac-terization 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.

    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.

    The spatiotemporal dynamics of an excitable medium with multiple spiral defects is shown to vary smoothly with system size from short-lived transients for small systems to extensive chaos for large systems. A comparison of the Lyapunov dimension density with the average spiral defect density suggests an average dimension per spiral defect varying between three and seven. We discuss some implications of these results for experimental studies of ventricular fibrillation.

    An injection barrel was designed and fabricated for a small size 0.8 mm cryogenic pellet with a low speed of 200-300 m/s in medium-sized plasma fusion devices. Pellet injection with pneumatic acceleration was examined using a conventional in situ technique. A tapered structure was applied in the downstream side of the injection barrel to satisfy the requirement of pellet speed reduction by expansion of the propellant gas. Shadowgraph and light gate measurements show that the intact pellets have speeds of 260 ± 30 m/s and a typical size of 1.1-1.2 mm. The pellet ablation code based on a neutral gas shielding model shows that the penetration depth of the measured pellet parameters does not cross the plasma center, even in medium-sized plasma devices such as the Heliotron J helical device. The injection barrel with a tapered structure developed in this study is feasible for low speed pellet injection.

    Neurolymphomatosis (NL) refers to nerve infiltration by neurotropic neoplastic cells in the setting of a known or an unknown hematological malignancy. It typically presents as painful or painless peripheral mononeuropathy, mononeuritis multiplex, polyneuropathy, polyradiculopathy, or cranial neuropathy. A 32-year-old male presented with a hyperpigmented hypoesthetic plaque over the anterolateral aspect of the right leg with thickening of the right common peroneal nerve and foot drop clinically diagnosed as Hansen's disease. Biopsy taken from skin showed infiltrates of pleomorphic small and medium sized lymphocytes in the dermis and subcutis. On immunohistochemistry, the cells were positive for CD3, CD4 and negative for CD8, CD20, and CD30. Ultrasonography-guided fine-needle aspiration of the thickened nerve showed infiltrates of atypical lymphoid cells. Based on these findings, a diagnosis of NL in primary cutaneous CD4+ pleomorphic small/medium-sized T-cell lymphoma was made. The disease responded to systemic chemotherapy and localized radiotherapy with no evidence of relapse during 3 years follow-up. NL in primary cutaneous CD4+ pleomorphic small/medium-sized T-cell lymphoma presenting with manifestations redolent of Hansen's disease is not described in available literature. This case also demonstrates the utility of fine needle aspiration of nerve, a minimally invasive procedure in the diagnosis of NL.

    The tympanomeatal flap elevation technique has been used in tympanoplasty for decades; however, this procedure has disadvantages. In recent years, endoscopic transcanal myringoplasty (ETM) has been increasingly practiced and has yielded positive results.This study compares the efficacy of ETM and endoscopic type I tympanoplasty (ETT) in repairing medium-sized perforations of the tympanic membrane. This retrospective medical record review included patients undergoing surgery for medium-sized perforations of the tympanic membrane from January 1, 2013 to August 1, 2015. We divided our patients into 2 groups: the ETM group and ETT group. The main outcome measure was comparison of the graft take rates and hearing results between ETM and ETT. A total of 113 patients were enrolled in this study; of these patients, 64 underwent ETM and 49 received ETT. The overall graft take rates and improvement of air-bone gaps were comparable between the groups. However, the patients in the ETM group had shorter operative times and fewer follow-up visits over 3 months than those in the ETT group did. We recommend that ETM (instead of ETT) be used for repairing medium-sized perforations of the tympanic membrane. Copyright © 2017 Elsevier B.V. All rights reserved.

    Mixtures of polycylic aromatic hydrocarbons (PAHs) have been produced by means of laser pyrolysis. The main fraction of the extracted PAHs were primarily medium-sized, up to a maximum size of 38 carbon atoms per molecule. The use of different extraction solvents and subsequent chromatographic fractionation provided mixtures of different size distributions. UV-VIS absorption spectra have been measured at low temperature by matrix isolation spectroscopy and at room temperature with PAHs as film-like deposits on transparent substrates. In accordance with semi-empirical calculations, our findings suggest that large PAHs with sizes around 50 to 60 carbon atoms per molecule could be responsible for the interstellar UV bump at 217.5 nm.

  7. Predation selectively culls medium-sized species from island mammal faunas.

    Hanna, Emily; Cardillo, Marcel

    2014-01-01

    Globally, elevated extinction risk in mammals is strongly associated with large body size. However, in regions where introduced predators exert strong top-down pressure on mammal populations, the selectivity of extinctions may be skewed towards species of intermediate body size, leading to a hump-shaped relationship between size and extinction risk. The existence of this kind of extinction pattern, and its link to predation, has been contentious and difficult to demonstrate. Here, we test the hypothesis of a hump-shaped body size-extinction relationship, using a database of 927 island mammal populations. We show that the size-selectivity of extinctions on many islands has exceeded that expected under null models. On islands with introduced predators, extinctions are biased towards intermediate body sizes, but this bias does not occur on islands without predators. Hence, on islands with a large-bodied mammal fauna, predators are selectively culling species from the lower end of the size distribution, and on islands with a small-bodied fauna they are culling species from the upper end. These findings suggest that it will be difficult to use predictable generalizations about extinction patterns, such as a positive body size-extinction risk association, to anticipate future species declines and plan conservation strategies accordingly.

    Saika-Voivod, Ivan; Poon, Louis; Bowles, Richard K

    2010-08-21

    The free energy of a 600-atom Lennard-Jones cluster is calculated as a function of surface and bulk crystallinity in order to study the structural transformations that occur in the core of medium sized clusters. Within the order parameter range studied, we find the existence of two free energy minima at temperatures near freezing. One minimum, at low values of both bulk and surface order, belongs to the liquid phase. The second minimum exhibits a highly ordered core with a disordered surface and is related to structures containing a single fcc-tetrahedral subunit, with an edge length of seven atoms (l=7), located in the particle core. At lower temperatures, a third minimum appears at intermediate values of the bulk order parameter which is shown to be related to the formation of multiple l=6 tetrahedra in the core of the cluster. We also use molecular dynamics simulations to follow a series of nucleation events and find that the clusters freeze to structures containing l=5, 6, 7, and 8 sized tetrahedra as well as those containing no tetrahedral units. The structural correlations between bulk and surface order with the size of the tetrahedral units in the cluster core are examined. Finally, the relationships between the formation of fcc tetrahedral subunits in the core, the phase behavior of medium sized clusters and the nucleation of noncrystalline global structures such as icosahedra and decahedra are discussed.

    2011-10-01

    Small businesses need to engage in continuity planning to assure delivery of goods and services and to sustain the economy during an influenza pandemic. This is especially true in New York City, where 98 per cent of businesses have fewer than 100 employees. It was an objective therefore, to determine pandemic influenza business continuity practices and strategies suitable for small and medium-sized NYC businesses. The study design used focus groups, and the participants were owners and managers of businesses with fewer than 500 employees in New York City. The main outcome measures looked for were the degree of pandemic preparedness, and the feasibility of currently proposed business continuity strategies. Most participants reported that their businesses had no pandemic influenza plan. Agreement with feasibility of specific business continuity strategies was influenced by the type of business represented, cost of the strategy, and business size. It was concluded that recommendations for pandemic-related business continuity plans for small and medium-sized businesses should be tailored to the type and size of business and should highlight the broad utility of the proposed strategies to address a range of business stressors.

    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.

    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.

    Full Text Available Although the vision and mission are important to the strategic planning of a business and much time and effort are spent on their formulation, they aren’t used as planning instruments. The purpose of this paper was to determine whether management understands the vision and mission as complementary concepts and whether they use them effectively in the planning process. This study was conducted by sending questionnaires to businesses in the Gauteng Province where most SMEs in South Africa are situated. Findings confirmed that the majority of businesses, especially small businesses, can distinguish between and have visions and missions, but do not apply them optimally in strategy implementation. Recommendations include that businesses should have a written vision and mission statement, which should be communicated effectively and applied in planning and strategy implementation.

    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.

    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.

    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.

    2012-11-01

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

    Diego Castanera

    Full Text Available BACKGROUND: Recent work on the Jurassic-Cretaceous transition of the Iberian Range (Spain has opened a new window onto the interpretation of the trackmakers of some medium-sized tridactyl tracks. The ichnotaxon Therangospodus oncalensis has been described in the Huérteles Formation (Berriasian and is one of the classical tracks from the area assigned to medium-sized theropods. METHODOLOGY/PRINCIPAL FINDINGS: A review of the type locality of Therangospodus oncalensis (Fuentesalvo tracksite and other tracksites from the Huérteles Formation (Berriasian has yielded new information on the morphology, gait and trackmaker identity of the aforementioned ichnospecies. The new data suggest that the trackmaker is an ornithopod rather than a theropod on the basis of the length/width ratio, the anterior triangle length-width ratio, the short steps, the round to quadrangular heel pad impression and the probable manus impressions. CONCLUSIONS/SIGNIFICANCE: T. oncalensis shows similarities with various tracks from the Berriasian of Europe assigned to Iguanodontipus. The ichnotaxonomical status of this ichnospecies is here considered as Iguanodontipus? oncalensis due to the current state of knowledge of the ichnotaxonomy of medium-sized ornithopod tracks. This reassessment of I? oncalensis also has two significant implications for the palaeoecology of the faunas during the deposition of the Huérteles Formation: 1- the high number and percentage of theropod tracks would be lower than previous papers have suggested. 2- the gregarious behaviour described in the type locality (Fuentesalvo would be among ornithopods instead of theropods.

  9. THE RELATIONSHIP BETWEEN TANGIBLE ASSETS AND CAPITAL STRUCTURE OF SMALL AND MEDIUM-SIZED COMPANIES IN CROATIA

    Directory of Open Access Journals (Sweden)

    Martina Harc

    2015-07-01

    Full Text Available The asset structure of companies should matter for financing decisions. Small and medium-sized companies in Croatia may use tangible assets as collateral, either providing more access to creditors or as a guarantee in case of bankruptcy. The aim of this paper is to investigate the relationship between tangible assets and the capital structure of Croatian small and medium-sized enterprises. Most previous studies have shown various relationships between tangible assets and leverage. This study has been conducted on a sample of 500 Croatian SMEs for the period between 2005 and 2010. The data used for the empirical analysis were taken from companies’ annual reports. The Pearson Correlation Coefficient is applied in order to examine the relationship between tangible assets and leverage measures. The results of this research indicate that tangible assets are differently correlated with short-term and long-term leverage. The relationship between tangible assets and short-term leverage is negative and statistically significant in all observed years. The relationship between tangible assets and long-term leverage is positive in all observed years and statistically significant. The results show that small and medium-sized companies use their collateral to attract long-term debt, which means that small and medium-sized companies use lower costs and the interest rate of long-term debt in relation to short-term debt. These findings correspond with the maturity matching principle, according to which long-term assets are financed with long-term financing and short-term assets are financed with short-term funds. These results suggest that tangible assets have a positive impact on the long-term debt of Croatian SMEs because tangible assets constitute a positive signal to the financial institutions, which can request the selling of these assets in case of bankruptcy. These findings are consistent with the trade-off theory which predicts a positive relation

    We present studies for optimizing the next generation of ground-based imaging atmospheric Cherenkov telescopes (IACTs). Results focus on mid-sized telescopes (MSTs) for CTA, detecting very high energy gamma rays in the energy range from a few hundred GeV to a few tens of TeV. We describe a novel, flexible detector Monte Carlo package, FAST (FAst Simulation for imaging air cherenkov Telescopes), that we use to simulate different array and telescope designs. The simulation is somewhat simplified to allow for efficient exploration over a large telescope design parameter space. We investigate a wide range of telescope performance parameters including optical resolution, camera pixel size, and light collection area. In order to ensure a comparison of the arrays at their maximum sensitivity, we analyze the simulations with the most sensitive techniques used in the field, such as maximum likelihood template reconstruction and boosted decision trees for background rejection. Choosing telescope design parameters repre...

  15. Magic number behavior for heat capacities of medium sized classical Lennard-Jones clusters

    CERN Document Server

    Frantz, D D

    2001-01-01

    Monte Carlo methods were used to calculate heat capacities as functions of temperature for classical atomic clusters of aggregate sizes $25 \\leq N \\leq 60$ that were bound by pairwise Lennard-Jones potentials. The parallel tempering method was used to overcome convergence difficulties due to quasiergodicity in the solid-liquid phase-change regions. All of the clusters studied had pronounced peaks in their heat capacity curves, most of which corresponded to their solid-liquid phase-change regions. The heat capacity peak height and location exhibited two general trends as functions of cluster size: for $N = 25$ to 36, the peak temperature slowly increased, while the peak height slowly decreased, disappearing by $N = 37$; for $N = 30$, a very small secondary peak at very low temperature emerged and quickly increased in size and temperature as $N$ increased, becoming the dominant peak by $N = 36$.

    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 structural and rheological evolution of an initially disordered lamellar phase system under a shear flow is examined using a mesoscale model based on a free energy functional for the concentration field, which is the scaled difference in the concentration between the hydrophilic and hydrophobic components. The dimensionless numbers which affect the shear evolution are the Reynolds number (γ ˙ ¯ L2 /ν ) , the Schmidt number (ν /D ) , a dimensionless parameter Σ =(A λ2 /ρ ν2 ) , a parameter μr which represents the viscosity contrast between the hydrophilic and hydrophobic components, and (L /λ ) , the ratio of system size and layer spacing. Here, ρ, ν, and D are the density, kinematic viscosity (ratio of viscosity and density), and the mass diffusivity, and A is the energy density in the free energy functional which is proportional to the compression modulus. Two distinct modes of structural evolution are observed for moderate values of the parameter Σ depending only on the combination ScΣ and independent of system size. For ScΣ less than about 10, the layers tend to form before they are deformed by the mean shear, and layered but misaligned domains are initially formed, and these are deformed and rotated by the flow. In this case, the excess viscosity (difference between the viscosity and that for an aligned state) does not decrease to zero even after 1000 strain units, but appears to plateau to a steady state value. For ScΣ greater than about 10, layers are deformed by the mean shear before they are fully formed, and a well aligned lamellar phase with edge dislocation orders completely due to the cancellation of dislocations. The excess viscosity scales as t-1 in the long time limit. The maximum macroscopic viscosity (ratio of total stress and average strain rate over the entire sample) during the alignment process increases with the system size proportional to (L/λ ) 3 /2. For large values of Σ, there is localisation of shear at the walls

  18. Fast 3C 279 gamma flares by a merging medium size black hole jet aligned to the AGN one by tidal torque?

    The shorter-than-Schwarzschild 3C 279 variability flare on June 2015 is very puzzling. Its nature cannot naturally be due to a NS merging nor to a medium sized (a hundred solar masses) BH collapse onto the AGN. Our preliminary model is based on the long-life (nearly a year) merging of a medium size BH spiralling toward the largest AGN one, that is dragging by tidal torques the medium size BH jet along the same 3C 279 one, aligning both jets toward Earth. The twin overlapping blazars may offer at once a long and a short scale variability consistent with the surprising Fermi discover.

  19. Changes in concentration and size distribution of aerosols during fog over the south Indian Ocean

    Measurements of the concentration and size distribution of aerosol particles in the size-ranges of 0.5–20 m and 16–700 nm diameters were made during six fog episodes over the south Indian Ocean. Observations show that concentrations of particles of all sizes start decreasing 1–2 hours before the occurrence of fog. This decrease is more prominent for coarse particles of < 1 m diameter and continues until 10–20 minutes before the onset of fog when particle concentrations in all size ranges rapidly increase by one/two orders of magnitude in ∼20 minutes. Thereafter, concentrations of particles of all sizes gradually decrease until the dissipation of fog. After the fog dissipation, concentrations of coarse mode particles rapidly increase and restore to their pre-fog levels but concentrations of the Aitken mode particles decrease slowly and reach their pre-fog levels only after 1–2 hours. The net effect of fog is to change the bimodal size distributions of aerosols with a coarse mode at 1.0 m and an accumulation mode at 40–60 nm to a power law size distribution. It is proposed that the preferential growth and sedimentation of the coarse mode hygroscopic particles in the initial phase cause a large decrease in the aerosol surface area. As a result, the low vapour pressure gases which were initially being used for the growth of coarse mode particles, now accelerate the growth rates of the accumulation and Aitken mode particles.

    Seed tracer particles must be large enough to scatter sufficient light while being sufficiently small to follow the flow. These requirements motivate a desire for control over the particle size. For gas measurements, it is common to use atomized oil droplets as tracer particles. A Laskin nozzle is a device for generating oil droplets in air by directing high-pressure air through small holes under an oil surface. The droplet diameter frequency distribution can be varied by altering the hole diameter, the number of holes, or the inlet pressure. We will present a systematic study of the effect of these three parameters on the resultant particle distribution as it leaves the Laskin nozzle. The study was repeated for cases where the particles moved through a typical jet facility before their size was measured. While the jet facility resulted in an elimination of larger particles, the average particle diameter could be varied by a factor of two at both the seeder exit and downstream of the jet facility.

    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.

    Meteorite impacts are a common occurrence throughout Earth's geologic history. Many of the surface expressions of large ancient impacts have been subsequently erased by weathering and erosion processes. The study of preserved meteorite impacts is necessary to better understand this natural hazard which has been increasingly linked to rapid climate change and mass extinctions. The 60 ka Odessa meteorite crater located in Ector Co. Texas, is unique because it is not only well-preserved, but also has been the subject of extensive geologic examination. Geologic mapping and numeric models indicate that the crater was caused by a relatively small oblique impactor. The crater rim is remarkably well exposed. Much of the ejecta blanket is present, although deeply eroded. There has been considerable site disturbance due to drilling, shaft excavation, trenching, construction of a museum, trails, and the oil/gas activity in surrounding fields. Two previous geophysical investigations have shown that our data clearly corresponds to large-scale thrust deformation. With this in mind we have performed 3D high resolution magnetic gradiometer surveys that will allow us to quantify and characterize the magnetic signature of small to medium impacts. We will tie this data set to a 3D photorealistic outcrop image provided by laser scanning with coarser-scale, below-ground geophysical information. Our geophysical imagery provides a useful constraint on numerical simulations of the impact and its immediate regional-scale environmental effects. This information can be used to identify impact sites whose surface expression has been erased by natural erosional processes, allowing for improved frequency estimates and improved geo-hazard assessment.

    Full Text Available Nowadays, sources of competitive advantage and economic development are sought in the sphere of innovation. They are at the centre of interest of representatives of the world of politics, science, and business. Moreover, they have been incorporated into governmental and international strategic development programmes. This article attempts to characterize and evaluate cooperation in creating innovation in small and medium-sized enterprises in Poland. Empirical research, a fragment of which is presented in this article, was conducted at the turn of March and April 2015 on a representative sample of Polish small and medium-sized enterprises. The subject of the analysis was business innovation expressed through the indicators of innovation and frequency of cooperation with different entities from the business environment to create new solutions, as well as forms of business innovation. The evaluation of the existing dependence was performed on the basis of the estimation results of the logit model. The objective of this study was to identify key factors related to cooperation and their impact on the innovativeness of Polish companies, using the tools of econometric analysis. The article presents a contemporary approach to managing innovative activity – open innovation, which is both widely reported and reflected in the results of research conducted. The logit model that was developed also indicates that companies that are open to cooperation with customers and academic institutions of the Polish Academy of Sciences (PAN and are members of clusters are more likely to implement innovations of a radical nature.

    Obesity is a risk factor for the development of umbilical hernia. Open hernia closure could be challenging in obese patients leading to high rates of recurrence. The aim of this study was to investigate the effectiveness and safety of hernia patches in the management of obese patients with umbilical hernias. All the patients included in this study were managed in the department of surgery of a primary care hospital in Germany. The data of patients undergoing umbilical hernia repair within a two-year period was retrospectively reviewed. Patients managed with the PVP were included for analysis. 24 obese patients were analyzed. Small and medium size patches were used in 15 and 9 patients respectively. The median duration of surgery was 40 min and the median length of hospital stay was 4d. The mean length of follow-up was 12 ± 9 months (range: 6-30 months). The rate of recurrence was 4.1% and the rate of complication was 8.3%. Obese patients presenting with small and medium size umbilical hernias could be safely and effectively managed with prosthetic patches like the Proceed Ventral Patch. However, the limited overlap zone following hernia closure with such a patch can be an issue.

    Full Text Available Small and medium-sized enterprises play an important role in the European economy as a source of entrepreneurial skills, innovation and employment. Strategic management is vital for long-term competitiveness of these organizations, and even more significant when struggling with a crisis. Enterprises with strategic management are able to look into their future and their managers are able to recognize upcoming issues in advance so they are much better prepared for them. Crisis is then perceived as a phenomenon which is more common than rare. It is therefore essential that businesses reflect the aspects and impacts of the crisis in a corporate strategy and managers learn to manage crises effectively. The article deals with a partial research of the management of small and medium-sized enterprises in the Czech Republic. It is focused on defining a strategy by the managers of these organizations and the assessment of the significance of crises. Only about 25% of the companies formulated a strategy for the future direction of the organization. The crises happen in all organizations, varying in degrees and intensity. The importance of crisis is evaluated by the managers by an average rate of 3.4 (where the highest rate was five. The aim of the article is an assessment of the importance of crisis as seen by the managers in strategically managed organizations structured according to sectors of the economy. For primary data collection, the questionnaire method was used.

  7. Determining Sustainable Land Use by Modal Split Shift Strategy for Low Emissions: Evidence from Medium-Sized Cities of China

    Full Text Available The rapid urbanization in medium-sized cities in China has led to revolution of transportation systems resulting in negative impacts on the environment. Evaluating the relationship among land use, modal split, and traffic emission can help propose regional optimal land use pattern by modal shift strategy to reduce carbon emissions. Data were collected from seven medium-sized cities in China. The study first evaluated the land use that influences mode split and the relationship between modal split and traffic emission. Then a sustainable mode shift strategy was provided to reduce emissions. Lastly, we provided constructive suggestions for sustainable land use pattern by mode shift strategy. To reduce emission per trip, nonmotorized trip modes and public transit should be increased, and, accordingly, the residence-industry and residence-retain mix entropy should be increased. The study found that the regions with job-housing balance or retail-housing mix could increase the mode share of nonmotorized vehicle traffic and reduce car use. The modal shift can in the future benefit emission reductions.

    This paper deals with the estimation of the performance of a medium-size aircraft (3-hour flight range) equipped with an adaptive trailing edge device (ATED) that runs span-wise from the wing root in the flap zone and extends chord-wise for a limited percentage of the MAC. Computations are calculated referring to the full wing and do not refer to the complete aircraft configuration. Aerodynamic computations, taking into account ideal shapes, have been performed by using both Euler and Navier- Stokes method in order to extract the wing polars for the reference and the optimal wing, implementing an ATED, deflected upwards and downwards. A comparison of the achieved results is discussed. Considering the shape domain, a suitable interpolation procedure has been set up to obtain the wing polar envelop of the adaptive wing, intended as the set of "best" values, picked by each different polar. At the end, the performances of the complete reference and adaptive wing are computed and compared for a symmetric, centered, leveled and steady cruise flight for a medium size aircraft. A significant fuel burn reduction estimate or, alternatively, an increased range capability is demonstrated, with margins of further improvements. The research leading to these results has gratefully received funding from the European Union Seventh Framework Programme (FP7/2007- 2013) under Grant Agreement n° 284562.

    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.

    2015-01-01

    Since the seventies, several reconstruction techniques have been proposed, and are currently used, to extrapolate and quantify eruptive parameters from sampled deposit datasets. Discrete numbers of tephra ground loadings or stratigraphic records are usually processed to estimate source eruptive values. Reconstruction techniques like Pyle, Power law and Weibull are adopted as standard to quantify the erupted mass (or volume) whereas Voronoi for reconstructing the granulometry. Reconstructed values can be affected by large uncertainty due to complexities occurring within the atmospheric dispersion and deposition of volcanic particles. Here we want to quantify the sensitivity of reconstruction techniques, and to quantify how much estimated values of mass and grain size differ from emitted and deposited ones. We adopted a numerical approach simulating with a dispersal code a mild explosive event occurring at Mt. Etna, with eruptive parameters similar to those estimated for eruptions occurred in the last decade. T...

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.

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

    Yielding and work-hardening phenomena in an Fe-10.62Mn-2.84Al-0.17C-0.5Mo steel, which is composed of nanometer-sized lamellae of α' and γ, are described on the basis of the Hall-Petch relations. Unlike the general expectation, yielding in the steel, which consists of lamellae of α' and mechanically stable γ, occurs through the propagation of pileup dislocations from α' to γ. However, when γ is mechanically unstable, yielding occurs through the stress-assisted martensitic transformation (SAMT) within the unstable γ region, resulting in a low YS of about 500 MPa. The overall prominent work-hardening behavior of this steel after yielding is due to the active SAMT, which does not accompany the increase in mobile dislocation density and so causes the high elastic strain rate. The carbon partitioning treatment increases the SAMT starting strength to about 980 MPa, which is caused by the mechanical stabilization of γ. The overall low work-hardening behavior of this case is mainly attributed to the active propagation of pile-up dislocation from α' to γ which causes the high plastic strain rate through the abrupt increase of mobile dislocation density.

    Currently there are no suitable wastewater treatment systems for effluents from small food processing industries (dairy, cheese, wine production). Such raw sewages are characterized by high organic matter concentrations (about 10 g COD L-1) and relatively low daily volumes (about 2 m3). An adaptation of attached-growth cultures on fine media processes, known to be easy and inexpensive to use, could fit both the technical and economical context of those industries. Coarser filter particle size distributions than those normally used allow a better aeration and reduce clogging risk. The transit time of the effluent through the porous filter materials is shortened and requires recycling to increase the contact time between the biomass and the substrate. A pilot plant was built to compare the efficiency of two kinds of filter materials, gravel (2-5 mm) and pozzolana (3-7 mm). Two measurement campaigns were undertaken on a full-scale unit dealing with cheese dairy effluents. Both pilot-scale and full-scale plants show high COD removal rates (> 95%). Pilot-scale experiments show that accumulation of organic matter leads to the clogging of the recycling filter. To prevent early clogging, a better definition of feeding cycles is needed.

    For a long time, under the influence of system and environment and other factors, some small and medium-sized agricultural enterprises in China only seek growth of profit in quantity, but neglect the growth of profit in quality, leading to low profit quality. This study reasonably defines the concept of profit quality of small and medium-sized agricultural enterprises, and expounds general characteristics of high quality profit. On the basis of general factors influencing profit quality of enterprises, it builds indicator system for evaluating the profit quality of small and medium-sized agricultural enterprises. Also, it conducts an empirical analysis on profit quality of Chinese small and medium-sized enterprises with YM Industrial Co., Ltd in Guang’an City of Sichuan Province as an example.

    Highlights: • Mn–Zn ferrite NPs were synthesized by two different methods are polyol and sonochemical. • The sonochemical method produced NPs with high crystallinity than polyol method. • The ferrite samples synthesized by sonochemical method showed high magnetization values and superparamagnetic properties. • XRD, TEM, EDS, TGA, FTIR, and VSM techniques used to characterize the samples. - Abstract: Monodisperse Mn{sub x}Zn{sub 1−x}Fe{sub 2}O{sub 4} (x = 0.2, 0.5 and 0.8) nanoparticles have been synthesized using two different routes namely sonochemical and polyol methods, and the shape and size along with physiochemical properties of the nanoparticles were compared in detail. In both the routes, the synthesis was performed in a single reaction without the use of any surfactant and deoxygenated conditions. The reaction kinetics and surface adsorption characteristics of nanoparticles were observed by thermogravimetric analysis and Fourier transform infrared spectroscopy measurements. X-ray diffraction patterns confirmed the formation of a pure ferrite phase with cubic spinel structure, and the patterns further clearly indicate that the sonochemical method produces highly crystalline particles without any post calcination reaction, comparing with the polyol process. Transmission electron microscopy results reveal that the nanoparticles synthesized by polyol method are mostly aggregated and spherical in nature whereas the nanoparticles produced by sonochemical method are monodisperse large particles with cubic like shapes. The overall studies demonstrated that the sonochemical method is facile, reliable, rapid and very attractive for the aqueous synthesis of highly crystalline and high magnetic moment (84.5 emu/g) monodisperse superparamagnetic Mn–Zn ferrite nanoparticles which considered as potential materials for various applications.

    Our understanding of mammal ecology has always been hindered by the difficulties of observing species in closed tropical forests. Camera trapping has become a major advance for monitoring terrestrial mammals in biodiversity rich ecosystems. Here we compiled one of the largest datasets of inventories of terrestrial mammal communities for the Neotropical region based on camera trapping studies. The dataset comprises 170 surveys of medium to large terrestrial mammals using camera traps conducted in 144 areas by 74 studies, covering six vegetation types of tropical and subtropical Atlantic Forest of South America (Brazil and Argentina), and present data on species composition and richness. The complete dataset comprises 53,438 independent records of 83 species of mammals, includes 10 species of marsupials, 15 rodents, 20 carnivores, 8 ungulates and 6 armadillos. Species richness averaged 13 species (± 6.07 SD) per site. Only six species occurred in more than 50% of the sites: the domestic dog Canis familiaris, crab-eating fox Cerdocyon thous, tayra Eira barbara, south American coati Nasua nasua, crab-eating raccoon Procyon cancrivorus and the nine-banded armadillo Dasypus novemcinctus. The information contained in this dataset can be used to understand macroecological patterns of biodiversity, community, and population structure, but also to evaluate the ecological consequences of fragmentation, defaunation, and trophic interactions.

  5. Anisotropic finite-size scaling of an elastic string at the depinning threshold in a random-periodic medium

    Full Text Available We numerically study the geometry of a driven elastic string at its sample-dependent depinning threshold in random-periodic media. We find that the anisotropic finite-size scaling of the average square width $overline{w^2}$ and of its associated probability distribution are both controlled by the ratio $k=M/L^{zeta_{dep}}$, where $zeta_{dep}$ is the random-manifold depinning roughness exponent, $L$ is the longitudinal size of the string and $M$ the transverse periodicity of the random medium. The rescaled average square width $overline{w^2}/L^{2zeta_{dep}}$ displays a non-trivial single minimum for a finite value of $k$. We show that the initial decrease for small $k$ reflects the crossover at $k sim 1$ from the random-periodic to the random-manifold roughness. The increase for very large $k$ implies that the increasingly rare critical configurations, accompanying the crossover to Gumbel critical-force statistics, display anomalous roughness properties: a transverse-periodicity scaling in spite that $overline{w^2} ll M$, and subleading corrections to the standard random-manifold longitudinal-size scaling. Our results are relevant tounderstanding the dimensional crossover from interface to particle depinning. Received: 20 October 2010, Accepted: 1 December 2010; Edited by:  A. Vindigni; Reviewed by: A.

    2002-01-01

    With the method of trend analysis of sediment grain size, the sediment transport trend of the fine-grained sediments area in the central South Yellow Sea was studied. The results demonstrated that there is a sedimentation center around the point of 123.4°E, 35.1°N, and the sediments outside the center are transported to it. The patterns of sediment transportation and deposition in the Yellow Sea should be controlled by cyclonic circulation (including the Yellow Sea Cold Water Mass) and cold water gyre. The study also showed that the method of trend analysis of sediment grain size has prospective utilization in the fine-grained sediment deposited area on large-scale continental shelf.

    2014-01-01

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

    2014-12-01

    This study examines the associations between neighbourhood perceptions and social participation in a sample of older adults living in medium-sized cities in Flanders, Belgium. Strong evidence of the influence of place on older people's physical and mental health exists. However, the question of how neighbourhoods promote or hinder social participation remains under-explored in social gerontology. Using data generated from the Belgian Ageing Studies, a multivariate regression model (n = 1877) is tested, with personal characteristics, subjective neighbourhood assessments and objective city-level measures as independent variables, and two indicators of social participation as dependent variables: social activity and formal participation. Positive predictors included neighbourhood involvement, frequent contact with neighbours and availability of activities for older people. However, the predictive role of neighbourhood perceptions is stronger for formal participation than for social activity, which is explained more by individual characteristics. The article concludes by discussing the implications of the findings for research and practice pertaining to health promotion interventions.

    Full Text Available In China, a large number of small and medium-sized food enterprises (food SMEs rarely adopt the hazard analysis and critical control points (HACCP system, which results in a low product quality. Some local governments have encouraged food SMEs to implement HACCP systems through financial subsidies, but because of an incomplete understanding of the willingness to pay (WTP for implementing HACCP systems in food SMEs, relevant policies have not enhanced the adoption rate of HACCP systems. Based on our questionnaire survey data of 132 food SMEs in China's Henan, Guangdong, and Zhejiang provinces, this study estimates Chinese food SMEs' WTP for implementing HACCP systems by a double bounded dichotomous choice contingent valuation method (CVM. According to the estimated results, the WTP for implementing HACCP systems under the log-logistic model is approximately 115,714 Chinese RMB (113,149 Chinese RMB for the log-normal model.

    Banjo G. Roxas

    2008-01-01

    Full Text Available This article proposes a conceptual framework that explains that the social capital of a community shapes the innovation performance of small and medium-sized enterprises (SMEs through knowledge management within the firm. The study's significance stems from the unprecedented effort in explaining how community social capital matters in the innovation performance of SMEs, a departure from previous studies that have typically examined market-related or hierarchical social capital in the form of formal networks and directly linked them to a firm's innovation performance without due regard for knowledge management within the firm as an antecedent of organisational innovation performance. The aim is to stimulate further thinking and empirical research on the subject of social capital of a community in the SME and/or entrepreneurial context.

    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.

    Gamma-ray observations in the very-high-energy domain (E > 30 GeV) can exploit the imaging of few-nanosecond Cherenkov flashes from atmospheric particle showers. Photomultipliers have been used as the primary photosensors to detect gamma-ray induced Cherenkov light for the past 25 years, but they are increasingly challenged by the swift progress of silicon photomultipliers (SiPMs). We are working to identify the optimal photosensors for medium-sized Schwarzschild-Couder telescopes (SCT), which are proposed to contribute a significant fraction of the sensitivity of the Cherenkov Telescope Array in its core energy range. We present the capabilities of the latest SiPMs from the Hamamatsu, SensL, and Excelitas companies that we have characterized in our laboratory, and compare them to the SiPMs equipping the prototype SCT camera that is under construction.

    2014-11-07

    Novel molecular scaffolds comprising two to four bridged and fused heterocycles were synthesized from amino acids using seven-membered endocyclic N-acyliminium ions as key intermediates in acid-mediated tandem reactions with internal nucleophiles. This complexity-generating synthesis proceeds with high efficiency and with full stereocontrol of the newly generated stereogenic center. These results have extended the scope of medium-sized cyclic iminium ion chemistry, making it applicable as a regio- and stereoselective synthetic strategy for the generation of complex polycyclic structures. Furthermore, its compatibility with the traditional Merrifield synthesis of peptides on solid supports allowed the incorporation of the previously unexplored conformationally restricted cyclic systems into peptides without a need to independently synthesize the scaffold.

    2011-01-01

    Management of medium to large-sized terrestrial mammals (Antilocapridae, Canidae, Cervidae, Leporidae, Mustelidae, Ochotonidae) in the western United States is multifaceted and complex. Species in this group generally are charismatic and provide economic opportunities, although others are considered a nuisance at one extreme or are listed as species of conservation concern at the other. Understanding the relative influence of land cover, habitat fragmentation, and human land use on their distribution during the breeding season is imperative to inform management decisions on land use and conservation planning for these species. We surveyed medium to large-sized sagebrush (Artemisia spp.)-associated mammal species in 2005 and 2006 on 141 random transects (mean length = 1.1 km) in the Wyoming Basins, an area undergoing rapid land cover transformation due to human actions including energy development. Overall, we observed 10 species but only obtained enough observations of pronghorn (Antilocapra americana) to develop spatially explicit distribution models. For pronghorn, occurrence related positively to proportion of sagebrush land cover within 0.27 km, mixed shrubland land cover within 3 km, riparian land cover within 5 km, Normalized Difference Vegetation Index (NDVI) within 0.27 km, road density within 5 km, and decay distance to power line corridors at 1 km, but negatively to salt-desert shrubland cover within 18 km and an interaction between sagebrush and NDVI within 0.27 km. We found excellent predictive capability of this model when evaluated with independent test data. The model provides a basis for assessing the effects of proposed development on pronghorn and can aid planning efforts to avoid or mitigate adverse effects on pronghorn.

    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.

    The meso-scale landscape dynamics model, CALEROS, has been developed to simulate the interactions between climate, soil production and erosion, vegetation and land use on geomorphological to human time scales in Mediterranean environments. Starting from an initial landscape consisting of a DTM, soil distribution and underlying lithology, the landscape is free to develop in response to the imposed climate variability and seismicity. In addition to changes in soil distribution and bedrock lowering, this includes the establishment of vegetation as conditioned by a selection of plant functional types and, optionally, population and land use dynamics as conditioned by land use scenarios specifying technological and dietary constraints for different periods. As such CALEROS is well-suited to investigate the relative impacts of climate, land cover and human activities on the hydrological catchment response and the associated sediment fluxes due to soil erosion and mass movements. Here we use CALEROS to i) investigate the redistribution of water and sediment across the landscape in a medium-sized Mediterranean catchment (Contrada Maddalena; ~14km2, Calabria, Italy) and ii) to establish patterns of co-evolution in soil properties and vegetation under pristine and anthropogenically impacted conditions on a millennium-scale. Using summary statistics to describe the emergent properties and to verify them against observations, we then delineate areas of uniform morphology and describe the various pathways of development. This information allows us to identify elements of consistent hydrological response and the associated transfer of material across different scales. It also provides essential information on essential feedbacks and the resulting convergence or divergence in landscape development under the impact of climatic or seismic events or human intervention. Although the results are evidently conditioned by the physiographic setting of the study area and by the

    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.

    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.

    Using radiotelemetry, we studied variation in home-range size of the Bachman's Sparrow (Aimophila aestivalis) at the Savannah River Site (SRS), South Carolina, during the 1995 breeding season. At SRS, sparrows occurred primarily in two habitats: mature pine habitats managed for Red-cockaded Woodpecker (Picoides borealis) and pine plantations 1 to 6 years of age. The mean 95% minimum convex polygon home-range size for males and females combined (n = 14) was 2.95 ha + 0.57 SE, across all habitats. Mean homerange size for males in mature pine stands (4.79 ha + 0.27, n = 4) was significantly larger than that in 4-year-old (3.00 ha + 0.31, n = 3) and 2-year-old stands (1.46 ha + 0.31, it = 3). Home-range sizes of paired males and females (it = 4 pairs) were similar within habitat type; mean distances between consecutive locations differed by habitat type and sex. We hypothesize that a gradient in food resources drives home-range dynamics.

    The transformation from Ag templates to Au-Ag nanoshells via galvanic replacement reaction with HAuCl{sub 4} was systematically studied in an organic medium in the presence of oleylamine. Decahedral ({approx}43 nm in size) and triangular prism ({approx}53 nm in edge length) Ag templates transformed into equiaxed and triangular prismatic Au-Ag nanoshells, respectively. The first step involved structural and morphological changes from Ag templates to Au-Ag nanoshells with an interior cavity. In the second step, the growth of the shells continued through the deposition of Au. The shell thickness increased from {approx}5 to {approx}10 nm for the equiaxed Au-Ag nanoshells ({approx}39-nm interior cavity) and {approx}5 to {approx}8 nm for the triangular prismatic Au-Ag nanoshells ({approx}52-nm interior edge length). Oleylamine not only served as a surfactant but also removed AgCl precipitates and reduced HAuCl{sub 4}. For the nanoshells derived from the {approx}20-nm Ag decahedrons, further reaction in excess HAuCl{sub 4} collapsed the nanoshells into Au-rich solid fragments. However, the nanoshells derived from the {approx}43-nm Ag decahedrons, the nanoshell structure not only persisted in excess HAuCl{sub 4}, but its shell thickness also increased. The size-dependent transformation of these nanoshells is discussed.

    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.

    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.

    Full Text Available In southern Italy many cities are characterized by a lack of public urban greenspaces. Non-urbanized areas in these cities are suffering from surrounding urbanization pressures. These areas still provide important ecosystem services even if they are limited in size, highly fragmented and often neglected by local planning. New planning strategies are needed in order to protect and enhance the provision of ecosystem services delivered by existing Non-Urbanized areas, but municipalities usually have limited funds for acquiring public green areas via land expropriations. At the same time, requests for new urban development are still considerable. Consequently, it is not realistic to propose strategies for green areas that do not include new developments. The paper illustrates a strategy for a Green Oriented Urban Development (GOUD that has been applied for the Master Plan of Catania, a medium sized city in Sicily (southern Italy. The strategy includes a limited amount of developments as well as new greenspaces in selected areas (Resource Zones, through the transfer of property and development rights between the municipality and developers. The strategy will allow to enhance the provision of ecosystem services, especially cultural services (thanks to a dramatic increase of accessibility to new greenspaces, regulating services (through climate regulation by new green land covers and provisioning services such as urban agricultural products. Results show that it is possible to improve urban ecosystem services creating a more liveable and healthy urban environment at reduced cost for the municipal administrations.

    The Cherenkov Telescope Array (CTA) is the next generation Very High Energy (VHE, defined as > 50GeV to several 100TeV) telescope facility, currently in the design and prototyping phase, and expected to come on-line around 2016. The array would have both a Northern and Southern hemisphere site, together delivering nearly complete sky coverage. The CTA array is planned to have ~100 telescopes of several different sizes to fulfill the sensitivity and energy coverage needs. Each telescope has a number of subsystems with varied hardware and control mechanisms; a drive system that gets commands and inputs via OPC UA (OPC Unified Architecture), mirror alignment systems based on XBee/ZigBee protocol and/or CAN bus, weather monitor accessed via serial/Ethernet ports, CCD cameras for calibration, Cherenkov camera, and the data read out electronics, etc. Integrating the control and data-acquisitions of such a distributed heterogeneous system calls for a framework that can handle such a multi-platform, multi-protocol scenario. The CORBA based ALMA Common software satisfies these needs very well and is currently being evaluated as the base software for developing the control system for CTA. A prototype for a Medium Size Telescope (MST, ~12m) is being developed and will be deployed in Berlin, by end of 2012. We present the development being carried out to integrate and control the various hardware subsystems of this MST prototype using ACS.

    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.

    Full Text Available This study sought to establish the social and environmental factors that influence sustainable entrepreneurship (SE in Small- and medium-sized enterprises (SMEs. It also attempted to identify whether the demographic background of the entrepreneur influences the SE in SMEs of the Iranian food industry. A mixed method approach, employing the use of questionnaires and interviews from a sample size of approximately 130 participants and 12 owner-managers of SMEs in food industry, was used to collect data. Data were analyzed using descriptive statistics and several inferential analyses. Findings showed that certain characteristics of the entrepreneur, including work experience and education, have a significant impact on SE. Furthermore, out of the eight identified factors, according to the participants’ perception, the most important factors towards sustainable performance of SMEs in food industry are social factors, including customer orientation, as well as human resources and environmental factors, including recycling and the future of Earth. This research paper concludes that considering the social and environmental aspects of sustainability and employing experienced staff would majorly contribute to the pursuit of SE in SMEs of food industry.

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

  4. CONSIDERATIONS REGARDING THE USE OF MODERN MANAGEMENT METHODS IN PLANNING THE MARKETING ACTIVITY WITHIN THE SMALL AND MEDIUM-SIZED ENTERPRISES

    Full Text Available This paper aims to highlight, from a marketing perspective, the manner and conditions in which small and medium-sized enterprises can use modern management methods in planning the marketing activity. Using modern methods of management are particularly important for managers of these organizations and especially for marketers. Thus, the following methods play a significant role within the marketing activitiesn#8217; development for marketing specialists, namely: management by objectives, management by budgets, management by projects, and management by product. The high degree of understanding and using the above methods is, in the current economic environment, one of the determinants of the market success of small and medium-sized enterprises. In the current context, the adoption of the management by objectives is not a facultative option for the small and medium-sized enterprises, but rather a binding one in the context of adopting and practicing an efficient marketing with significant results on the development of marketing programs comprised within them. Similarly to the management by objectives, the use of the management by budgets within the small and medium-sized enterprises has a series of features required by their smaller size, features that should be considered by marketers. Regarding the use of management by projects, this method has to constitute the foundation for the elaboration of marketing programs developed within the small and medium-sized enterprises, thereby allowing shaping an action that can be accompanied by success in achieving the goals comprised within the marketing programs. Finally, the role of the management by product is extremely important in the marketing activity within the small and medium-sized enterprises, especially in the operationalization of concepts such as strategic marketing and tactical marketing. This paper thus outlines from a marketing point of view the main issues aiming at understanding and using

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

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

    The population size and movement patterns of small fish (>50 mm SL) in a small intermittently open estuary (Grant's Valley estuary: 33°40'12.1″S, 26°42'12.6″E) situated on the south-east Cape coast of South Africa were examined during the closed phase over the period May and August 2004. The estuary was subdivided into four discrete areas and the fish within each area sampled using a 30 m seine net (15 mm mesh). Fish captured were marked by fin clipping according to the area of capture. Fish population size was estimated by using three methods: the Schnabel estimator, the Hilborn estimator, and a derived estimator. A total of 12 species was captured and marked during the study. The total number of fish in the estuary was estimated at ca. 12 000 individuals (11 219-13 311). Marine-breeding species ( Rhabdosargus holubi, Monodactylus falciformis, and two mullet species) numerically dominated the ichthyofauna, possibly as a result of their effective use of overtopping events, when seawater washes over the sandbar, to enter the estuary during the closed mouth phase. The two mullet species, Myxus capensis and Liza richardsonii, and the Cape stumpnose, R. holubi moved extensively throughout the estuary, while the remaining species exhibited restricted movement patterns possibly due to the preference for refuge and foraging areas associated with reed beds. The observed movement patterns of individual fish species appeared to be associated with both foraging behaviour and habitat selection.

    Full Text Available In modern conditions the region's sustainable development and economic growth is largely determined by its ability to implement innovations. One of the determining factors of long-term economic development of the territories, to date, is innovation. A mechanism to give impetus to the innovative development of the regions is to create effective small and medium-sized innovative enterprises. Voronezh region, like many Russian regions, has considerable potential for innovation, but usually it is not used efficiently or not used at all. The article deals with the concept and the need to develop innovative entrepreneurship and the role of small and medium innovative enterprises in the formation of scientific and technical potential of the Voronezh region. The basic conditions and factors promoting and impeding the development of small and medium innovative businesses in the region, determined the willingness of subjects of innovation activity in the development, implementation and promotion of innovation in the region. The problems of development of small and medium-sized businesses at the regional level. The evaluation of actions to improve SMEs management programs in the region.

    Size of methyl ricinoleate droplets during biotransformation into gamma-decalactone by Yarrowia lipolytica was measured in both homogenized and non-homogenized media. In non-homogenized but shaken medium, droplets had an average volume surface diameter d32 of 2.5 microm whereas it was 0.7 microm in homogenized and shaken medium. But as soon as yeast cells were inoculated, both diameters became similar at about 0.7 microm and did not vary significantly until the end of the culture. The growth of Y. lipolytica in both media was very similar except for the lag phase which was lowered in homogenized medium conditions.

    Aims and Objectives: Attainment of ideal occlusion is often restricted by disproportionate sizes of individual teeth, which is otherwise termed as tooth size discrepancy (TSD). While extraction of teeth for orthodontic purposes is not uncommon, there is considerable resistance against this school of thought. The extraction of premolars, in particular, received considerable attention because of the potential TSD that could result following the extraction of premolars. The aim of the present study was to identify the consequence of premolar extractions on Bolton's overall ratios in South Indian population. Materials and Methods: One hundred participants were recruited into the study through purposive nonproportionate quota sampling. Pretreatment dental casts of the study participants were measured for mesiodistal tooth widths to determine Bolton's overall ratio before the hypothetical tooth extractions were performed. The hypothetical extractions were executed in four different combinations as follows: (a) Maxillary and mandibular first premolars, (b) maxillary first premolars and mandibular second premolars, (c) maxillary second premolars and mandibular first premolars, and (d) maxillary and mandibular second premolars. Bolton's overall ratios were calculated after the hypothetical tooth extractions were performed. Statistical analysis was done using the Statistical Package for the Social Sciences, version 20 software. Results: It was observed that extractions performed in any of the combinations followed in this study resulted in a decrease of overall Bolton's ratios. However, the discrepancy in tooth size was highest with the extraction of all first premolars, whereas least discrepancy was recorded with all second premolars extraction. It was also found that, based on the combination of teeth chosen for extraction, there was significant difference in Bolton's overall ratios between males and females. Conclusion: In formulating a treatment plan involving premolar

  11. 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 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.

    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.

    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.

    Ultrafine particles (UFP) have attracted much attention in recent years due to their influence on atmospheric concentrations of cloud condensation nuclei (CCN) and the consequent effect on cloud albedo and global climate. To understand UFP lifetime in the atmosphere, both sources and sinks need to be known. One important sink for UFP is removal by vegetation. The main collection mechanism by vegetation is Brownian diffusion with a possible contribution of electrostatic forces. Here we report measurements of collection efficiency of UFP by pine and juniper branches in a wind tunnel at different wind speeds, branch orientations, and packing densities. The effect of particle charge is also investigated. Two modeling approached have been developed to describe UFP deposition to vegetation branches. One treats vegetation as a fibrous filter with a characteristic fiber size; the other treats it as a random porous medium. The experiments agreed well with predictions from both models within 20%. Upon bridging these two modeling approaches, estimates of the effective fiber diameter can now be derived from conventional canopy attributes, such as the leaf area index. These results can benefit future air quality and climate models incorporating UFP.

    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.

    Providing the best care in both the inpatient and outpatient settings to pediatric oncology patients is all programs goal. Using continuous improvement methodologies, we changed from a solely team-based physician care model to a hybrid model. All patients were assigned a dedicated oncologist. There would then be 2 types of weeks of outpatient clinical service. A "Doc of the Day" week where each oncologist would have a specific day in clinic when their assigned patients would be scheduled, and then a "Doc of the Week" week where one physician would cover clinic for the week. Patient satisfaction surveys done before and 14 months after changing the model of care showed that patients were very satisfied with the care they received in both models. A questionnaire to staff 14 months after changing showed that the biggest effect was increased continuity of care, followed by more efficient clinic workflow and increased consistency of care. Staff felt it provided better planning and delivery of care. A hybrid model of care with a primary physician for each patient and assigned clinic days, alternating with weeks of single physician coverage is a feasible model of care for a medium-sized pediatric oncology program.

    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.

    In this study a fesibility design study of medium sized (1000 MWt) gas cooled fast reactors which can utilize natural uranium as fuel cycle input has been conducted. Gas Cooled Fast Reactor (GFR) is among six types of Generation IV Nuclear Power Plants. GFR with its hard neuron spectrum is superior for closed fuel cycle, and its ability to be operated in high temperature (850° C) makes various options of utilizations become possible. To obtain the capability of consuming natural uranium as fuel cycle input, modified CANDLE burn-up scheme[1-6] is adopted this GFR system by dividing the core into 10 parts of equal volume axially. Due to the limitation of thermal hydraulic aspects, the average power density of the proposed design is selected about 70 W/cc. As an optimization results, a design of 1000 MWt reactors which can be operated 10 years without refueling and fuel shuffling and just need natural uranium as fuel cycle input is discussed. The average discharge burn-up is about 280 GWd/ton HM. Enough margin for criticallity was obtained for this reactor.

    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.

    2015-02-01

    Full Text Available The manufacturing of medium-sized hollow parts using a foamed high density polyethylene was studied using a conventional accumulator blow extrusion machine and a systematic capture of pictures during the parison formation. To fully monitor the parison formation, several experiments were carried out varying the chemical foaming agent content from 0 wt.% to 2 wt.% and increasing the push extrusion speed. Results pointed out greater wall thickness, diameter, and length of parisons with higher weight percentage of blowing agent and extrusion speed. A full experimental characterisation of parison dimensions was essential to assure a proper prediction of the blowing step. Information was used as input for modelling and simulations of the blowing phase of an industrial container. To validate the proposed methodology, a blow moulding process of a generic container was simulated using Ansys Polyflow v13 software and its finite element analysis which provided an accurate approximation of the wall thickness expected. Further real tests on the simulated container also demonstrated that, in those parisons with a 1 wt.% CFA concentration and higher blowing pressure, there was remarkable improvement on their packaging properties such as decreasing of the total weight of the container and an enhancement of its surface quality.

    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.

    In Uganda, a low-income country in east Africa, African swine fever (ASF) is endemic with yearly outbreaks. In the prevailing smallholder subsistence farming systems, farm biosecurity is largely non-existent. Outbreaks of ASF, particularly in smallholder farms, often go unreported, creating significant epidemiological knowledge gaps. The continuous circulation of ASF in smallholder settings also creates biosecurity challenges for larger farms. In this study, an on-going outbreak of ASF in an endemic area was investigated on farm level, including analyses of on-farm environmental virus contamination. The study was carried out on a medium-sized pig farm with 35 adult pigs and 103 piglets or growers at the onset of the outbreak. Within 3 months, all pigs had died or were slaughtered. The study included interviews with farm representatives as well as biological and environmental sampling. ASF was confirmed by the presence of ASF virus (ASFV) genomic material in biological (blood, serum) and environmental (soil, water, feed, manure) samples by real-time PCR. The ASFV-positive biological samples confirmed the clinical assessment and were consistent with known virus characteristics. Most environmental samples were found to be positive. Assessment of farm biosecurity, interviews, and the results from the biological and environmental samples revealed that breaches and non-compliance with biosecurity protocols most likely led to the introduction and within-farm spread of the virus. The information derived from this study provides valuable insight regarding the implementation of biosecurity measures, particularly in endemic areas.

    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.

    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.

    Full Text Available The purpose of this article is to understand the barriers faced by small and medium-sized enterprises in their path to internationalization. The intention of this paper is to provide an overview about the barriers faced by SMEs in their path to internationalization and discuss in detail different approaches taken by SMEs to overcome these barriers. This article is a literature review on the barriers faced by SMEs in internationalization and new approaches in this domain based on Leonidou’s (1995, 1998, 2004 model of export barrier classification. Modern approaches by SMEs are effective in handling most of the traditional challenges posed in internationalization. Firms have evolved in handling internal barriers by finding dynamic solutions from within. SMEs need support from governmental and policy makers to overcome external barriers. Indications on the work to be done in overcoming certain barriers which impede the internationalization of SMEs are more in the context of external barriers. The originality of this work is in creating a framework of barriers and finding solutions to some of the identified barriers.

    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.

    Medium-sized spiny neurons (MSNs) are the only neostriatum projection neurons, and their degeneration underlies some of the clinical features of Huntington's disease. Using knowledge of human developmental biology and exposure to key neurodevelopmental molecules, human pluripotent stem (hPS) cells were induced to differentiate into MSNs. In a feeder-free adherent culture, ventral telencephalic specification is induced by BMP/TGFβ inhibition and subsequent SHH/DKK1 treatment. The emerging FOXG1(+)/GSX2(+) telencephalic progenitors are then terminally differentiated, resulting in the systematic line-independent generation of FOXP1(+)/FOXP2(+)/CTIP2(+)/calbindin(+)/DARPP-32(+) MSNs. Similar to mature MSNs, these neurons carry dopamine and A2a receptors, elicit a typical firing pattern and show inhibitory postsynaptic currents, as well as dopamine neuromodulation and synaptic integration ability in vivo. When transplanted into the striatum of quinolinic acid-lesioned rats, hPS-derived neurons survive and differentiate into DARPP-32(+) neurons, leading to a restoration of apomorphine-induced rotation behavior. In summary, hPS cells can be efficiently driven to acquire a functional striatal fate using an ontogeny-recapitulating stepwise method that represents a platform for in vitro human developmental neurobiology studies and drug screening approaches.

    2011-07-01

    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.

  12. Impact of local urban design and traffic restrictions on air quality in a medium-sized town.

    2012-01-01

    Traffic is the major air pollution source in most urban areas. Nowadays, most of the strategies carried out to improve urban air quality are focused on reducing traffic emissions. Nevertheless, acting locally on urban design can also reduce levels of air pollutants. In this paper, both strategies are studied in several scenarios for a medium-sized town of the Basque Country (Spain). Two main actions are analysed in order to reduce traffic emissions: (1) minor extension ofa pre-existing low emission zone (LEZ); (2) substitution of 10% of passenger cars that are older than 5 years by hybrid and electric vehicles. Regarding local urban design, three alternatives for the development of one side of a street canyon are considered: (1) a park with trees; (2) an open space without obstacles; (3) a building. Two different urban traffic dispersion models are used to calculate the air quality scenarios: PROKAS (Gaussian&box) to analyse the reduction of traffic emissions in the whole urban area and WinMISKAM (CFD) to evaluate specific urban designs. The results show the effectiveness of the analysed actions. On one hand, the definition of a small LEZ, as well as the introduction in 2015 of vehicles with new technology (hybrid and electric), results in minor impacts on PM10 and NO2 ambient concentrations. On the other hand, local urban design can cause significant variation in spatial distribution ofpollutant concentrations emitted inside street canyons. Consequently, urban planners should consider all these aspects when dealing with urban air pollution control.

    Full Text Available Corporate social responsibility (CSR has become increasingly important to the competitiveness of small and medium-sized enterprises (SMEs. A positive relationship between the CSR activities of SMEs and their enhanced competitiveness exists, at least if a long-term perspective is adopted (European Competitiveness Report, 2008:106; Mandl & Dorr, 2007:2. Despite the widespread practical and academic interest in CSR and its impact on the competitiveness of SMEs, few theoretical and empirical contributions could be found. The primary objective of this study was to identify and empirically test the CSR factors influencing the competitiveness of SMEs in Uganda. The outcomes of this study will assist SMEs to effectively and responsibly manage their activities to increase their competitiveness. A structured, self-administered questionnaire was distributed to 750 potential SME respondents. The respondents were identified by means of a purposive sampling technique, and the data were collected from 383 usable questionnaires. An exploratory factor analysis was carried out, and Cronbach’s alpha coefficients calculated to determine the discriminant validity and reliability of the measuring instrument. Correlations were assessed using structural equation modeling. The empirical results of this study indicate that workforce-oriented CSR activities, society-oriented CSR activities, market-oriented CSR activities and regulated CSR activities significantly influence the competitiveness of SMEs.

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

    Compared with the large-sized enterprises, the small and medium-sized enterprises have the characteristics of small scale, low management level, fragile fund basis and low capacity to resist business risk and external impact. Starting with the problems faced by the small and medium-sized enterprises in modern competition and informatization process, this paper explores the concrete policies and measures the small and medium-sized enterprises should adopt in the informatization construction.

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

    2013-04-01

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

    A previously developed model was modified to derive three phytoplankton size classes (micro-,nano-,and pico-phytoplankton) from the overall chlorophyll-a concentration,assuming that each class has a specific absorption coefficient.The modified model performed well using in-situ data from the northern South China Sea,and the results were reliable and accurate.The relative errors of the size-fractioned chlorophyll-a concentration for each size class were:micro-:21%,nano-:41%,pico-:26%,and nano+pico:23%.The model was then applied on ocean color remote sensing data to examine the distribution and variation of phytoplankton size classes in northern South China Sea on a large scale.

    Light-absorbing dissolved organic carbon (DOC) constitutes a major part of the organic carbon in glacierized regions, and has important influences on the carbon cycle and radiative forcing of glaciers. However, few DOC data are currently available from the glacierized regions of the Tibetan Plateau (TP). In this study, DOC characteristics of a medium-sized valley glacier (Laohugou Glacier No. 12, LHG) on the northern TP were investigated. Generally, DOC concentrations on LHG were comparable to those in other regions around the world. DOC concentrations in snow pits, surface snow and surface ice (superimposed ice) were 332 ± 132, 229 ± 104 and 426 ± 270 µg L-1, respectively. The average discharge-weighted DOC of proglacial stream water was 238 ± 96 µg L-1, and the annual DOC flux released from this glacier was estimated to be 6949 kg C yr-1, of which 46.2 % of DOC was bioavailable and could be decomposed into CO2 within 1 month of its release. The mass absorption cross section (MAC) of DOC at 365 nm was 1.4 ± 0.4 m2 g-1 in snow and 1.3 ± 0.7 m2 g-1 in ice, similar to the values for dust transported from adjacent deserts. Moreover, there was a significant relationship between DOC and Ca2+; therefore, mineral dust transported from adjacent arid regions likely made important contributions to DOC of the glacierized regions, although contributions from autochthonous carbon and autochthonous/heterotrophic microbial activity cannot be ruled out. The radiative forcing of snow pit DOC was calculated to be 0.43 W m-2, demonstrating that DOC in snow needs to be taken into consideration in accelerating melt of glaciers on the TP.

    The incidence and findings of tuberculous invasion of the peripheral bronchus have not been fully investigated with MDCT. Purpose To evaluate the prevalence and findings of MDCT abnormalities of small- and medium-sized bronchus (SMB) in active pulmonary tuberculosis (TB). Using multiplanar reformation, 35 consecutive MDCT scans (follow-up exams available in 14 patients with a mean interval of 8.1 months) were assessed for following abnormalities of SMB: bronchial impaction (BI), wall thickening, dilatation, peribronchial cuff of soft tissue, and bronchocavitary fistula. It was also assessed whether tree-in-buds (TIB) have a tendency to distribute in the territories of diseased SMB, and whether SMB abnormalities are present in patients with relatively mild disease. SMB abnormalities were observed in 23 (65.7%) patients with active TB. The most frequent finding was wall thickening (n = 18, 51.4%), followed by BI (n = 13, 37.1%; zigzag-shaped in four), dilatation (n = 11, 31.4%), amputated appearance of air column (n = 11, 31.4%), peribronchial cuff of soft tissue (n = 10, 28.6%), and bronchocavitary fistula (n =8, 22.9%). TIB (n = 29; absent in two patients with SMB) was mainly within (n = 14) or close to (n = 4) the territory of diseased SMB. Follow-up CT frequently showed improvement of wall thickening (11/12) and persistence of bronchial dilatation (11/13). SMB abnormality was present in all of six patients with mild disease. MDCT shows that tuberculous invasion of the peripheral bronchus may be more frequent than previously thought, of which findings include wall thickening, BI, dilatation, amputated appearance of air column, peribronchial cuff of soft tissue and bronchocavitary fistula.

    Full Text Available There is a demonstrable association between exposure to air pollutants and deaths due to cardiovascular diseases. The objective of this study was to estimate the effects of exposure to sulfur dioxide on mortality due to circulatory diseases in individuals 50 years of age or older residing in São José dos Campos, SP. This was a time-series ecological study for the years 2003 to 2007 using information on deaths due to circulatory disease obtained from Datasus reports. Data on daily levels of pollutants, particulate matter, sulfur dioxide (SO2, ozone, temperature, and humidity were obtained from the São Paulo State Environmental Agency. Moving average models for 2 to 7 days were calculated by Poisson regression using the R software. Exposure to SO2 was analyzed using a unipollutant, bipollutant or multipollutant model adjusted for mean temperature and humidity. The relative risks with 95%CI were obtained and the percent decrease in risk was calculated. There were 1928 deaths with a daily mean (± SD of 1.05 ± 1.03 (range: 0-6. Exposure to SO2 was significantly associated with mortality due to circulatory disease: RR = 1.04 (95%CI = 1.01 to 1.06 in the 7-day moving average, after adjusting for ozone. There was an 8.5% decrease in risk in the multipollutant model, proportional to a decrease of SO2 concentrations. The results of this study suggest that residents of medium-sized Brazilian cities with characteristics similar to those of São José dos Campos probably have health problems due to exposure to air pollutants.

    2014-11-01

    Full Text Available : INTRODUCTION: There are several studies on the microstructure of main arteries of the body but limited have been dealt with the neck arteries. It has been mentioned that the vascular pathologies like the thrombo-embolism, atherosclerosis and infarction are common in the branches of vertebral and internal carotid artery as compared to the branches of external carotid artery. OBJECTIVE: To study the histological structure of the 3 medium sized arteries of neck namely external carotid, internal carotid and vertebral artery, calculation of their mean pulse pressure and pulsatory power and to find any association between them if present. METHOD: Fresh samples of external carotid, internal carotid and vertebral artery each measuring 10mm in length were taken from five cadavers and prepared for histological examination under microscope using orcein and H&E stain. The mean pressure and pulsatory power of these arteries were calculated by taking the measurements such as wall thickness, lumen circumference, arterial wall area, and smooth muscle fibre density in tunica media in that arterial segment. RESULT: The pulsatory power of external carotid artery, internal carotid artery and vertebral artery is found to be 120, 273.3, 400 Joules /heart beat and the mean pressure is 17.1 mm Hg, 27.3 mm Hg and 33.3 mm Hg respectively. CONCLUSION: The thickness of tunica media of an artery is directly proportional to its pulsatory power. The mean pulse pressure, pulsatory power as well the number of smooth muscles fibres in tunica media are more in internal carotid artery and vertebral artery in comparison to external carotid artery. It may be a very important reason why vascular pathologies are less common in branches of external carotid as compare to internal carotid and vertebral artery.

    Full Text Available Orientation: The paper investigates the situation facing SME’s in Nigeria, who have to function in an environment with depleted infrastructure.Research purpose: To examine the effects of infrastructure deficiency on the performance of manufacturing small and medium sized enterprises in Nigeria.Motivation for the study: Low budgetary allocation by the Nigerian government toward investment and rehabilitation of infrastructure in favor of attempts to conform to the tenets of trade liberalisation, has created a situation where basic infrastructure provision is a huge challenge in the creation of SME’s.Research design, approach and method: A longitudinal approach was followed, where a survey was conducted amongst 500 SME’s in Nigeria. To complement this, semi-structured interviews were conducted in 2007 and 2011 respectively. Main findings: The deficiency in infrastructure negatively impacts the profitability and performance of SMEs, due to the high cost incurred by SMEs in the self-provision of infrastructure and distribution of finished goods. Furthermore, despite the successful privatisation of electricity production in November 2013, there is still no significant improvement in the power supply in Nigeria. However, the government has embarked on road rehabilitation to ease the transportation of goods and services.Practical/managerial implications: The study uncovers the practical realities of the challenges faced by SME’s operating in an environment with insufficient infrastructure, which is typical of much of the developing world.Contribution/value add: The study highlights the necessity of sound infrastructure provision as a key factor to the development of SME’s.

  5. Development of a Low NOx Medium sized Industrial Gas Turbine Operating on Hydrogen-Rich Renewable and Opportunity Fuels

    This report presents the accomplishments at the completion of the DOE sponsored project (Contract # DE-FC26-09NT05873) undertaken by Solar Turbines Incorporated. The objective of this 54-month project was to develop a low NOx combustion system for a medium sized industrial gas turbine engine operating on Hydrogen-rich renewable and opportunity Fuels. The work in this project was focused on development of a combustion system sized for 15MW Titan 130 gas turbine engine based on design analysis and rig test results. Although detailed engine evaluation of the complete system is required prior to commercial application, those tasks were beyond the scope of this DOE sponsored project. The project tasks were organized in three stages, Stages 2 through 4. In Stage 2 of this project, Solar Turbines Incorporated characterized the low emission capability of current Titan 130 SoLoNOx fuel injector while operating on a matrix of fuel blends with varying Hydrogen concentration. The mapping in this phase was performed on a fuel injector designed for natural gas operation. Favorable test results were obtained in this phase on emissions and operability. However, the resulting fuel supply pressure needed to operate the engine with the lower Wobbe Index opportunity fuels would require additional gas compression, resulting in parasitic load and reduced thermal efficiency. In Stage 3, Solar characterized the pressure loss in the fuel injector and developed modifications to the fuel injection system through detailed network analysis. In this modification, only the fuel delivery flowpath was modified and the air-side of the injector and the premixing passages were not altered. The modified injector was fabricated and tested and verified to produce similar operability and emissions as the Stage 2 results. In parallel, Solar also fabricated a dual fuel capable injector with the same air-side flowpath to improve commercialization potential. This injector was also test verified to produce 15

    Marcelo André Machado

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

    We report long-term changes in population size of three species of sympatrically breeding pygoscelid penguins: Adélie (Pygoscelis adeliae), chinstrap (Pygoscelis antarctica) and gentoo (Pygoscelis papua ellsworthii) over a 38 year period at Signy Island, South Orkney Islands, based on annual counts from selected colonies and decadal all-island systematic counts of occupied nests. Comparing total numbers of breeding pairs over the whole island from 1978/79 to 2015/16 revealed varying fortunes: gentoo penguin pairs increased by 255%, (3.5% per annum), chinstrap penguins declined by 68% (-3.6% per annum) and Adélie penguins declined by 42% (-1.5% per annum). The chinstrap population has declined steadily over the last four decades. In contrast, Adélie and gentoo penguins have experienced phases of population increase and decline. Annual surveys of selected chinstrap and Adélie colonies produced similar trends from those revealed by island-wide surveys, allowing total island population trends to be inferred relatively well. However, while the annual colony counts of chinstrap and Adélie penguins showed a trend consistent in direction with the results from all-island surveys, the magnitude of estimated population change was markedly different between colony wide and all island counts. Annual population patterns suggest that pair numbers in the study areas partly reflect immigration and emigration of nesting birds between different parts of the island. Breeding success for all three species remained broadly stable over time in the annually monitored colonies. Breeding success rates in gentoo and chinstrap penguins were strongly correlated, despite the differing trends in population size. This study shows the importance of effective, standardised monitoring to accurately determine long-term population trajectories. Our results indicate significant declines in the Adélie and chinstrap penguin populations at Signy Island over the last five decades, and a gradual

    Full Text Available The Welsh-medium education system has long been seen as an effective tool of Welsh language production in Wales. The aim of this paper is to provide an overview of Welsh medium education in one south Wales Valley, ‘Cwm Rhymni / Rhymni Valley’. The main reasoning behind the primary research is to focus on the reasons why non-Welsh speaking parents chose Welsh medium education for their children. The research focuses on education but recognises the over lapping nature of the main language transmission spheres within Welsh language planning, i.e. family,community and workplace. This study adopts a mainly qualitative research strategy by administering 60 unstructured interviews to parents who chose Welsh medium nursery, primary and secondary schools for their children. However, as a secondary methodological tool, a semi-structured questionnaire was given out prior to the interviews and the interview sample was then drawn from these. Moreover, Welsh language resurgence within Anglicized areas of South Wales is a fairly unexplored field, this study is hoped to be a catalyst for many more future studies in this field and attempts to address the existing lacunae.

    Full Text Available Purpose - The purpose of this paper is to ask one question. How the implementation of the requirements of ISO 9001 system affects the costs of running the business? Design/methodology/approach - The research covered time from 2006 to 2011 and was an attempt to assess the impact of the maintenance of the ISO 9001 Quality Management System on the costs of small and medium sized business organizations. The main objective was the selection of right research subjects that would allow the formulation of the most reliable and statistically valid conclusions. For this purpose we obtained permissions to conduct research in organizations characterized by comparable futures such as size, industry, type of business and strategy. Findings - The study shows that the costs associated with the implementation and maintenance of the Quality Management System standard is still too high, and effectively discourages representatives of small and medium-sized commercial organizations from implementing ISO 9001 system.

    Spatial distribution of phaeopigment and size-fractionated chlorophyll a (Chl a) concentrations were examined in relation to hydrographic conditions in the northern South China Sea (NSCS) during a survey from 20 August to 12 September, 2014. The total Chl a concentration varied from 0.006 to 1.488 µg/L with a mean value of 0.259±0.247 (mean±standard deviation) µg/L. Chl a concentration was generally higher in shallow water (200 m), with mean values of 0.364±0.311 µg/L and 0.206±0.192 µg/L respectively. Vertically, the maximum total Chl a concentration appeared at depths of 30-50 m and gradually decreased below 100 m. The size-fractionated Chl a concentrations of grid stations and time-series stations (SEATS and J4) were determined, with values of pico- (0.7-2 µm), nano- (2-20 µm) and micro-plankton (20-200 µm) ranging from 0.001-0.287 (0.093±0.071 µg/L), 0.004-1.149 (0.148±0.192 µg/L) and 0.001-0.208 (0.023±0.036 µg/L), respectively. Phaeopigment concentrations were determined at specific depths at ten stations, except for at station A9, and varied from 0.007 to 0.572 (0.127±0.164) µg/L. Nano-and pico-plankton were the major contributors to total phytoplankton biomass, accounting for 50.99%±15.01% and 39.30%±15.41%, respectively, whereas microplankton only accounted for 9.39%±8.66%. The results indicate that the contributions of microplankton to total Chl a biomass were less important than picoplankton or nanoplankton in the surveyed NSCS. Different sized-Chl a had similar spatial patterns, with peak values all observed in subsurface waters (30-50 m). The summer monsoon, Kuroshio waters, Zhujiang (Pearl) River plume, and hydrological conditions are speculated to be the factors controlling the abundance and spatial heterogeneity of Chl a biomass in the NSCS.

    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

    Arid environments are often remote, expansive, difficult to access and especially vulnerable to flash flood hazards due to the poor understanding of the phenomenon and the lack of meteorological, geomorphological, and hydrological data. For many years, catchment characteristics have been observed using point-based measurements such as rain gauges and soil sample analysis; on the other hand, use of remote sensing technologies can provide spatially continuous hydrological parameters and variables. The advances in remote sensing technologies can provide new geo-spatial data using high spatial and temporal resolution for basin-scale geomorphological analysis and hydrological models. This study used high spatial resolution remote sensing for hydro-geomorphologic analysis of the arid medium size Rahaf watershed (76 km2), located in the Judean Desert, Israel. During the research a high resolution geomorphological map of Rahaf basin was created using WorldView-2 multispectral satellite imageries; surface roughness was estimated using SIR-C and COSMO-SkyMed Synthetic Aperture Radar (SAR) spaceborne sensors; and rainstorm characteristics were extracted using ground-based meteorological radar. The geomorphological mapping of Rahaf into 17 classes with good accuracy. The surface roughness extraction using SAR over the basin showed that the correlation between the COSMO-SkyMed backscatter coefficient and the surface roughness was very strong with an R2 of 0.97. This study showed that using x-band spaceborne sensors with high spatial resolution, such as COSMO-SkyMed, are more suitable for surface roughness evaluation in flat arid environments and should be in favor with longer wavelength operating sensors such as the SIR-C. The current study presents an innovative method to evaluate Manning's hydraulic roughness coefficient (n) in arid environments using radar backscattering. The weather radar rainfall data was calibrated using rain gauges located in the watershed. The

  7. Striatal medium-sized spiny neurons: identification by nuclear staining and study of neuronal subpopulations in BAC transgenic mice.

    Directory of Open Access Journals (Sweden)

    Full Text Available Precise identification of neuronal populations is a major challenge in neuroscience. In the striatum, more than 95% of neurons are GABAergic medium-sized spiny neurons (MSNs, which form two intermingled populations distinguished by their projections and protein content. Those expressing dopamine D(1-receptors (D1Rs project preferentially to the substantia nigra pars reticulata (SNr, whereas those expressing dopamine D(2- receptors (D2Rs project preferentially to the lateral part of the globus pallidus (LGP. The degree of segregation of these populations has been a continuous subject of debate, and the recent introduction of bacterial artificial chromosome (BAC transgenic mice expressing fluorescent proteins driven by specific promoters was a major progress to facilitate striatal neuron identification. However, the fraction of MSNs labeled in these mice has been recently called into question, casting doubt on the generality of results obtained with such approaches. Here, we performed an in-depth quantitative analysis of striatal neurons in drd1a-EGFP and drd2-EGFP mice. We first quantified neuronal and non-neuronal populations in the striatum, based on nuclear staining with TO-PRO-3, and immunolabeling for NeuN, DARPP-32 (dopamine- and cAMP-regulated phosphoprotein Mr approximately 32,000, and various markers for interneurons. TO-PRO-3 staining was sufficient to identify MSNs by their typical nuclear morphology and, with a good probability, interneuron populations. In drd1a-EGFP/drd2-EGFP double transgenic mice all MSNs expressed EGFP, which was driven in about half of them by drd1a promoter. Retrograde labeling showed that all MSNs projecting to the SNr expressed D1R and very few D2R (<1%. In contrast, our results were compatible with the existence of some D1R-EGFP-expressing fibers giving off terminals in the LGP. Thus, our study shows that nuclear staining is a simple method for identifying MSNs and other striatal neurons. It also

    Regular physical activity (PA) promotes and excessive sedentary behavior (SB) deteriorates health. Yet the Finnish working-aged population spends most of the day sitting. A 1-year Moving To Business (MTB) -intervention supported small and medium-size workplaces to combat sedentariness. This paper reports the changes in employees' PA and SB from before MTB (baseline) to 1 year after baseline (follow-up). Twelve workplaces with a total of 396 employees participated. Each workplace nominated a team to promote PA and reduce SB at organizational, working unit and employee level. The teams were mentored regionally through meetings, workshop and tools. Changes in PA and SB were assessed with a questionnaire and an accelerometer. Wald Confidence Interval (Cl) for a difference of proportions with matched pairs was used in the questionnaire data (%-points with 95% CI) and linear mixed model in the accelerometer data (minutes and % of wear-time with 95% CI). The mean age of the respondents to the questionnaire (N = 296; 75%) was 42.6 (SD 10.9), 64% were women, 95% had some education after high school, 74% worked in the day shift, 71% did sedentary work and 51% were overweight. The mean number of actions implemented in the workplaces was 6.8 and the multilevel approach was fully applied in 6 workplaces. Based on the questionnaire the time spent in SB decreased from baseline to follow-up 16% (95% CI -29 to -3) in total and 22% (-41 to -3) at work. The accelerometer showed daily increases of 33.7 min (15.3 to 52.1) and 6.8% (3.1 to 10.4) in total PA, 30.9 min (15.3 to 46.5) and 6.1% (2.9 to 9.2) in light PA and 673 (209 to 1139) more steps at work. Daily SB at work decreased 44.9 min (-68.0 to -21.8) and 7.6% (-11.9 to -3.2). Daily leisure PA declined 11.0 min (-24.9 to 2.9) and 3.2% (-6.2 to -0.2). Number of levels or actions had no effect on changes. Employees' PA increased and SB reduced at work during the intervention. At the same time leisure PA decreased slightly

    Full Text Available The improvement of the short- and mid-range numerical runoff forecasts over the flood-prone Spanish Mediterranean area is a challenging issue. This work analyses four intense precipitation events which produced floods of different magnitude over the Llobregat river basin, a medium size catchment located in Catalonia, north-eastern Spain. One of them was a devasting flash flood – known as the "Montserrat" event – which produced 5 fatalities and material losses estimated at about 65 million euros. The characterization of the Llobregat basin's hydrological response to these floods is first assessed by using rain-gauge data and the Hydrologic Engineering Center's Hydrological Modeling System (HEC-HMS runoff model. In second place, the non-hydrostatic fifth-generation Pennsylvania State University/NCAR mesoscale model (MM5 is nested within the ECMWF large-scale forecast fields in a set of 54 h period simulations to provide quantitative precipitation forecasts (QPFs for each hydrometeorological episode. The hydrological model is forced with these QPFs to evaluate the reliability of the resulting discharge forecasts, while an ensemble prediction system (EPS based on perturbed atmospheric initial and boundary conditions has been designed to test the value of a probabilistic strategy versus the previous deterministic approach.

    Full Text Available In the framework of AMPHORE, an INTERREG III B EU project devoted to the hydrometeorological modeling study of heavy precipitation episodes resulting in flood events and the improvement of the operational hydrometeorological forecasts for the prediction and prevention of flood risks in the Western Mediterranean area, a hydrometeorological model intercomparison has been carried out, in order to estimate the uncertainties associated with the discharge predictions. The analysis is performed for an intense precipitation event selected as a case study within the project, which affected northern Italy and caused a flood event in the upper Reno river basin, a medium size catchment in the Emilia-Romagna Region.

    Two different hydrological models have been implemented over the basin: HEC-HMS and TOPKAPI which are driven in two ways. Firstly, stream-flow simulations obtained by using precipitation observations as input data are evaluated, in order to be aware of the performance of the two hydrological models. Secondly, the rainfall-runoff models have been forced with rainfall forecast fields provided by mesoscale atmospheric model simulations in order to evaluate the reliability of the discharge forecasts resulting by the one-way coupling. The quantitative precipitation forecasts (QPFs are provided by the numerical mesoscale models COSMO and MM5.

    Furthermore, different configurations of COSMO and MM5 have been adopted, trying to improve the description of the phenomena determining the precipitation amounts. In particular, the impacts of using different initial and boundary conditions, different mesoscale models and of increasing the horizontal model resolutions are investigated. The accuracy of QPFs is assessed in a threefold procedure. First, these are checked against the observed spatial rainfall accumulations over northern Italy. Second, the spatial and temporal simulated distributions are also examined over the catchment of interest

    In April 2010 the Dutch decree on emission limit values (ELVs) on medium-sized combustion installations entered into force. Bems sets ELVs for NOx, SO2, PM and CxHy. In 2013 the Bems legislation was transferred to the Activities Decree (In Dutch: Ab - Activiteitenbesluit). At the same time the Industrial Emissions Directive (IED) was implemented in the Ab. At the time Bems entered into force, it was decided to evaluate this legislation in 2014. Due to incorporation of Bems and the implementation of the IED in the Ab, it was decided to perform this evaluation a year earlier, thereby enabling the consideration of several stakeholders' comments on these implementations. This report presents the main conclusions of this evaluation. In Bems, combustion installations smaller than 50 MWth have to comply with ELVs based on Best Available Technology (BAT). Five possible ELVs have been discussed but not implemented in Bems, due to a lack of knowledge. These ELVs have been included in this evaluation. For gas engines < 2.5 MWth the NOx ELV could be more stringent, namely 140 mg/Nm{sup 3} instead of 340 mg/Nm{sup 3}; all ELVs are set at dry conditions in the flue gas and 3% O2. For biogas engines, introduction of the same ELV might be postponed until a comparable ELV enters into force in 2016 in a Californian region. Both the Californian ELV and this ELV need a gas cleaning technology. For (bio)diesel engines the dust ELV could be more stringent, namely 15 mg PM/Nm{sup 3} instead of 50 mg PM/Nm{sup 3}, while for NOx the ELV can be tightened from 450 mg/Nm{sup 3} to 250 mg/Nm{sup 3}. Both ELVs may be postponed until Tier 4 limits in the USA enter into force in the period 2014-2017. The Netherlands is one of the very few countries with CxHy ELVs for gas engines. The current CxHy ELV of 1500 mg C/Nm{sup 3} may be tightened to 1200 mg C/Nm{sup 3}. Other issues and changes, directly related to the Dutch legislation, have been discussed as well. These include exemption rules

    Using density functional theory calculations, we compared four kinds of possible structural motifs of the medium-sized Aun (n = 21-28) clusters, i.e., fcc-like, double-layered flat, tubular cage, and close-packed. Our results show strong competition between those structural motifs in the medium-sized gold clusters. Aun (n = 21-23) adopt fcc-like structure owing to the high stability of tetrahedral Au20. A structural transition from fcc-like to tubular occurs at Au24, and the tubular motif continues at Au27 and Au28. Meanwhile, a double-layered flat structure was found at Au25, and a pyramid-based structure at Au26. The relationship between electronic properties and cluster geometry was also discussed.
