    Get PDF
    How should intellectual property (IP) be protected and appropriated to gain value for the firm? This study aims to answer this question by examining the impact of the key determinants of IP appropriability, namely organizational resources, IP management practices and organizational learning culture, on innovation performance. The study uses quantitative survey data obtained from the Australian biotechnology, pharmaceutical and ICT industries in order to test several hypotheses. Our results show that exploitation and protection of IP within an organisational learning culture have a significant effect on the firm's innovation performance. The implication for managers is that IP appropriation is likely to be most successful when trade secrets and profits from innovation are applied simultaneously within an organizational learning culture

    Purpose – The purpose of this paper is to examine the impact of operations and maintenance (O&M) practices, individually and collectively, on power plant performance. Design/methodology/approach – Data were collected from more than 100 power plants in Australia and Malaysia. The reliability and validity (content, construct, and criterion) of the practice and performance measures were evaluated. Findings – Committed leadership and maintenance-oriented practices as part of a total productive maintenance (TPM) philosophy were found to be the main differentiators between high and low performing plants. Research limitations/implications – The research is cross-sectional in nature, therefore, it does not permit us to account for the lag between implementation and performance. Second, the performance measures are subjective and may be subject to response bias. Practical implications – The implication of the research findings for plant managers is that they need to allocate more β€œsofter” resources to the O&M function if they expect high plant availability. Social implications – Apart from capacity and fuel cost, operating costs are an important source of differentiation for power plants. The implication is that reduction in operating costs is directly related to the reduction of consumer power bills. Originality/value – The reader will learn from this paper that committed leadership and maintenance-oriented practices have greater explanatory power in the regression models than employee involvement, customer focus, strategic planning, and knowledge management. This knowledge is important because it emphasises that in addition to quality management practices, which are focussed on the development of the people aspects of the organization, the plant equipment and physical assets should also be given equal emphasis, in order to improve operational performance of power plants

    Entangled-state cycles from conditional quantum evolution

    Get PDF
    A system of cascaded qubits interacting via the oneway exchange of photons is studied. While for general operating conditions the system evolves to a superposition of Bell states (a dark state) in the long-time limit, under a particular resonance condition no steady state is reached within a finite time. We analyze the conditional quantum evolution (quantum trajectories) to characterize the asymptotic behavior under this resonance condition. A distinct bimodality is observed: for perfect qubit coupling, the system either evolves to a maximally entangled Bell state without emitting photons (the dark state), or executes a sustained entangled-state cycle - random switching between a pair of Bell states while emitting a continuous photon stream; for imperfect coupling, two entangled-state cycles coexist, between which a random selection is made from one quantum trajectory to another.Comment: 12 pages, 10 figure

    The use of GNSS zenith total delays in operational AROME/Hungary 3D-Var over a central European domain

    Get PDF
    The delay of satellite signals broadcasted by Global Navigation Satellite System (GNSS) provides unique atmospheric observations which endorse numerical weather prediction from global to limited-area models. Due to the possibility of its frequent and near-real-time estimation, the zenith total delays (ZTDs) are valuable information for any state-of-the-art data assimilation system. This article introduces the data assimilation of ZTDs in a Hungarian numerical weather prediction system, which was carried out by taking into account observations from central European GNSS analysis and processing centres. The importance of ZTD observations is described and shown by a diagnostic tool in the 3-hourly updated 3D-Var assimilation scheme. Furthermore, observing system experiments are done to evaluate the impact of GNSS ZTDs on mesoscale limited-area forecasts. The results of the use of GNSS ZTDs showed a clear added value to improve screen-level temperature and humidity forecasts when the bias is accurately estimated and corrected in the data assimilation scheme. The importance of variational, i.e. adaptive bias correction, is highlighted by verification scores compared to static bias correction. Moreover, this paper reviews the quality control of GNSS ground-based stations inside the central European domain, the calculation of optimal thinning distance and the preparation of the two above-mentioned bias correction methods. Finally, conclusions are drawn on different settings of the forecast and analysis experiments with a brief future outlook.</p

At the end of the XX century, systematic investigations of health promotion effects of wine were began. The obtained results showed that positive activity of wine directly depends on the content and bioavailability of phenolic compounds. Researches, involving more than 3,700 published papers, indicate that beer is also a significant source of phenolic and other bioactive compounds with prophylactic action and positive effects on human health. The phenolic compounds in beer and wine are quantitatively and qualitatively different, but red wines contain a much higher concentration of these compounds compared with beer. The main objective of this dissertation was to investigate the possibility of unite of positive effects of these two beverages through the contribution to the development and optimization of technological production process of special type of beer from wort and grape mash. The basic hypotesis was that the resulting grape beers will have higher biological value and increased functionality compared to commercial lager beer, but also pleasant sensory characteristics and an acceptable price in the market. In the experimental production of special grape beers three grape varieties were used: prokupac, cabernet sauvignon and pinot noir. The following parameters of production were examined: the optimal proportion of grapes in the fermentation medium, the possibility of using different yeast strains in the production, dynamic of fermentations, the impact of autochthonous grape microflora on the products quality, and dynamics of phenolic compounds extraction. Twelve different grape beers (four beers from each grape variety) and two control beers without the addition of grape were produced. Also, wines from each grape variety were produced according to the procedure for the production of red wines..

    Red raspberry (Rubus idaeus) juice was produced by maceration of raspberry pulp at 50 Β°C for 2 h using 400 mg kg Klerzyme150 enzymatic pectolitic preparation followed by raw juice clarification with gelatin and bentonite or cross-flow membrane filtration. A minimal loss of anthocyanins from 630 to 540 mg l was obtained when the juice was clarified using a ceramic multichannel microfilter (MF) with a pore size of 0.2 ΞΌm. A light transmission at 625 nm in MF permeate was above 85% and the residual pectin (900 mg l) was completely removed. During ultrafiltration through ceramic or polysulfone membranes with a molecular weight cut-off of 30-300 kDa, the content of anthocyanins was reduced to 220-370 mg l, but a light transmission at 625 nm was as high as 96%. The permeate flux in MF was maintained at high values above 170 l m h at 3 bar for more than 2 h by backwashing the membrane with a compressed air every 6 min for 1 min. The cake compression at high pressures was avoided by short filtration times between backwashing

    Get PDF
    Local domestic Kombucha was used in fermentation of 1.5 g L-1 of black tea (Indian tea, " Vitamin ", HorgoΕ‘, Serbia and Montenegro), sweetened with approximately 70 g L'1 of sucrose. Inoculation was performed either with 10% or 15% (v/v) of fermentation broth from previous process. The fermentation was conducted in geometrically similar vessels with 0.4 L, 0.8 L, 4 L and 8 L of substrate, at 22Β±1 Β°C for 28 days. The samples were analyzed after 3, 4 5, 6, 7, 10, 14 and 28 days, so that their pH values, content of total acids sucrose, glucose and fructose contents, as well as contents of ethanol and vitamin C were determined. Based on the experiment design, the response surface for the product pH, as a function of time, beverage volume and inoculum concentration, was defined in the form of a second-order polynomial. From the obtained response surface, a formula for scaling-up of the process was derived
