NewConnect - an alternative platform for new innovative companies
The article discusses the attributes of innovation in the context of creating a knowledge-based economy and presents the alternative stock market NewConnect where the small and medium-sized firms may seek funds to finance their innovative projects. NewConnect's functions and goals are shown with respect to capital circulation, stock market training, education and promotion of SMEs aspiring to enter the Warsaw Stock Exchange in the future, as well as the expansion of the financial infrastructure in Poland and the EU.W artykule zaprezentowano atrybuty innowacyjności w kontekście kreacji Gospodarki Opartej na Wiedzy oraz alternatywny parkiet NewConnect, stanowiący szanse pozyskiwania kapitału na nowatorskie projekty przez małe i średnie firmy. Wskazano na realizowane funkcje i zadania NewConnect w dziele przepływu kapitału, treningu giełdowego, edukacji i promocji małych i średnich spółek aspirujących w przyszłości do zajęcia pozycji na GPW oraz rozbudowy infrastruktury finansowej Polski i Unii Europejskiej
Microstructure evolution in aluminium 6060 during incremental ECAP
An AA6060 Al-Mg-Si alloy was used to investigate the microstructure evolution on X, Y and Z planes after processing by Incremental Equal Channel Angular Pressing (IECAP) at room temperature after 1 and 4 passes. The basic microstructural parameters (mean grain size, grain boundary statistics) were evaluated

Dynamics and Critical Behaviour of the q-model
The -model, a random walk model rich in behaviour and applications, is
investigated. We introduce and motivate the -model via its application
proposed by Coppersmith {\em et al.} to the flow of stress through granular
matter at rest. For a special value of its parameters the -model has a
critical point that we analyse. To characterise the critical point we imagine
that a uniform load has been applied to the top of the granular medium and we
study the evolution with depth of fluctuations in the distribution of load.
Close to the critical point explicit calculation reveals that the evolution of
load exhibits scaling behaviour analogous to thermodynamic critical phenomena.
The critical behaviour is remarkably tractable: the harvest of analytic results
includes scaling functions that describe the evolution of the variance of the
load distribution close to the critical point and of the entire load
distribution right at the critical point, values of the associated critical
exponents, and determination of the upper critical dimension. These results are
of intrinsic interest as a tractable example of a random critical point. Of the
many applications of the q-model, the critical behaviour is particularly
relevant to network models of river basins, as we briefly discuss. Finally we
discuss circumstances under which quantum network models that describe the
surface electronic states of a quantum Hall multilayer can be mapped onto the
classical -model. For mesoscopic multilayers of finite circumference the
mapping fails; instead a mapping to a ferromagnetic supersymmetric spin chain
has proved fruitful. We discuss aspects of the superspin mapping and give a new
elementary derivation of it making use of operator rather than functional
methods.Comment: 34 pages, Revtex, typo correcte
Evolution of airway inflammation in preschoolers with asthma : results of a two-year longitudinal study
Fractional exhaled nitric oxide (FeNO) is a non-invasive marker for eosinophilic airway inflammation and has been used for monitoring asthma. Here, we assess the characteristics of FeNO from preschool to school age, in parallel with asthma activity. A total of 167 asthmatic children and 66 healthy, age-matched controls were included in the 2-year prospective PreDicta study evaluating wheeze/asthma persistence in preschool-aged children. Information on asthma/rhinitis activity, infections and atopy was recorded at baseline. Follow-up visits were performed at 6-month intervals, as well as upon exacerbation/cold and 4-6 weeks later in the asthmatic group. We obtained 539 FeNO measurements from asthmatics and 42 from controls. At baseline, FeNO values did not differ between the two groups (median: 3.0 ppb vs. 2.0 ppb, respectively). FeNO values at 6, 12, 18 and 24 months (4.0, CI: 0.0-8.6; 6.0, CI: 2.8-12.0; 8.0, CI: 4.0-14.0; 8.5, CI: 4.4-14.5 ppb, respectively) increased with age (correlation p <= 0.001) and atopy (p = 0.03). FeNO was non-significantly increased from baseline to the symptomatic visit, while it decreased after convalescence (p = 0.007). Markers of disease activity, such as wheezing episodes and days with asthma were associated with increased FeNO values during the study (p < 0.05 for all). Age, atopy and disease activity were found to be important FeNO determinants in preschool children. Longitudinal and individualized FeNO assessment may be valuable in monitoring asthmatic children with recurrent wheezing or mild asthma
