Carbon dioxide emission during forest fires ignited by lightning
Magdalena Pelc,Radoslaw Osuch
Physics , 2009,
Abstract: In this paper we developed the model for the carbon dioxide emission from forest fire. The master equation for the spreading of the carbon dioxide to atmosphere is the hyperbolic diffusion equation. In the paper we study forest fire ignited by lightning. In that case the fores fire has the well defined front which propagates with finite velocity.
Nuclear survivin expression is a positive prognostic factor in taxane-platinum-treated ovarian cancer patients
Anna Felisiak-Golabek, Alina Rembiszewska, Iwona K Rzepecka, Lukasz Szafron, Radoslaw Madry, Magdalena Murawska, Tomasz Napiorkowski, Piotr Sobiczewski, Beata Osuch, Jolanta Kupryjanczyk, the Polish Ovarian Cancer Study Group (POCSG)
Journal of Ovarian Research , 2011, DOI: 10.1186/1757-2215-4-20
Abstract: Survivin and TP53 expression was evaluated immunohistochemically in 435 archival samples of ovarian carcinomas (244 patients were treated with platinum/cyclophosphamide-PC/PAC; 191-with taxane-platinum (TP) agents). Univariate and multivariate statistical analyses were performed in patients groups divided according to the administered chemotherapeutic regimen, and in subgroups with and without TP53 accumulation (TP53+ and TP53-, respectively).Nuclear and cytoplasmic survivin expression was observed in 92% and 74% of the carcinomas, respectively. In patients treated with TP, high nuclear survivin expression decreased the risk of disease recurrence and death, and increased the probability of high platinum sensitivity (p < 0.01), but only in the TP53(+) group, and not in the TP53(-) group.It appears that TP53 status determines the clinical importance of nuclear survivin expression in taxane-platinum treated ovarian cancer patients.Recently molecular anticancer therapies have undergone rapid development. Survivin, the smallest member of the family of the protein inhibitors of apoptosis (IAP) [1], is considered to be a potential target for molecular therapy [2]. Target survivin arose from data obtained from cancer cell lines, showing that survivin inhibition contributes to increased tumour response to various anticancer agents [3]. The results of clinical analyses are less consistent, as high survivin expression had been associated with both favourable and unfavourable prognosis [4].Ovarian cancer is the most lethal gynaecological malignancy. In the last decade, taxanes combined with cisplatin or its analogues (TP therapy) have been considered standard first-line treatment for ovarian cancer [5,6]. Although the introduction of taxanes has significantly improved treatment results, still 20% to 30% of the patients fail to achieve complete remission [6-8].Taxanes interact with β-tubulin and increase its polymerisation and stabilisation.

Bridge Structures with GFRP Composite Deck  [PDF]
Beata Stankiewicz
Open Journal of Civil Engineering (OJCE) , 2015, DOI: 10.4236/ojce.2015.51006
Abstract: In this paper, author’s first part of research of GFRP bridge deck (using ASSET fiber line composite modular system) took part at AGH University of Science and Technology Laboratory of Glass Technology and Amorphous Coatings Department. The analysis consisted spectrometer analysis of chemical constitution of glass fiber, identification of material according to Fourier spectroscopy, electronic scan microscopy (SEM/EDAX) and DTA analysis. The modal FEM analysis of chosen footbridge with light GFRP deck has been presented in the paper.

Rational Cost Estimation of Dedicated Software Systems  [PDF]
Beata Czarnacka-Chrobot
Journal of Software Engineering and Applications (JSEA) , 2012, DOI: 10.4236/jsea.2012.54031
Abstract: Dedicated software systems hold a character of individual solutions that entail particular problems with regard to their cost estimation. Thus for many years now objective and reliable approaches to the cost estimation of such systems have been sought out so that they could provide the possibility to make rational investment decisions concerning those systems. The purpose of this paper is to bring in the approach to cost estimation of dedicated software systems that has been recently growing in global popularity, using it as a background for presenting conclusions resulting from practical verification of author’s own model of dedicated software system cost estimation based on that approach.
Analysis of Software Development and Enhancement Projects Work Effort per Unit Based on the COSMIC Method with Regard to Technological Factors—Case Study  [PDF]
Beata Czarnacka-Chrobot
Journal of Software Engineering and Applications (JSEA) , 2013, DOI: 10.4236/jsea.2013.611072
Abstract:

This paper aims to present a case study that consists in the analysis of work effort per unit of software systems Development and Enhancement Projects (D&EP) depending on technological factors. That analysis was commissioned by one of the largest public institutions in Poland. This is the COSMIC (Common Software Measurement International Consortium) function points method that is chosen by this institution as a point of reference for size of software systems developed/enhanced for supporting its functions and therefore this method is the base for the analysis of D&EP work effort per unit with regard to technological factors.

Contractive projections in Orlicz sequence spaces
Beata Randrianantoanina
Abstract and Applied Analysis , 2004, DOI: 10.1155/s108533750431105x
Abstract: We characterize norm-one complemented subspaces of Orlicz sequence spaces ℓM equipped with either Luxemburg or Orlicz norm, provided that the Orlicz function M is sufficiently smooth and sufficiently different from the square function. We measure smoothness of M using AC1 and AC2 classes introduced by Maleev and Troyanski in 1991, and the condition for M to be different from a square function is essentially a requirement that the second derivative M″ of M cannot have a finite nonzero limit at zero. This paper treats the real case; the complex case follows from previously known results.
Increase of the Photocatalytic Activity of by Carbon and Iron Modifications
Beata Tryba
International Journal of Photoenergy , 2008, DOI: 10.1155/2008/721824
Abstract: Modification of TiO2 by doping of a residue carbon and iron can give enhanced photoactivity of TiO2. Iron adsorbed on the surface of TiO2 can be an electron or hole scavenger and results in the improvement of the separation of free carriers. The presence of carbon can increase the concentration of organic pollutants on the surface of TiO2 facilitating the contact of the reactive species with the organic molecules. Carbon-doped TiO2 can extend the absorption of the light to the visible region and makes the photocatalysts active under visible-light irradiation. It was proved that TiO2 modified by carbon and iron can work in both photocatalysis and photo-Fenton processes, when H2O2 is used, enhancing markedly the rate of the organic compounds decomposition such as phenol, humic acids and dyes. The photocatalytic decomposition of organic compounds on TiO2 modified by iron and carbon is going by the complex reactions of iron with the intermediates, what significantly accelerate the process of their decomposition. The presence of carbon in such photocatalyst retards the inconvenient reaction of OH radicals scavenging by H2O2, which occurs when Fe-TiO2 photocatalyst is used.

Effects of Interviewee's Job Experience and Gender on Ratings and Reliability in a Behavioral Interview
Choragwicka,Beata;
Revista de Psicología del Trabajo y de las Organizaciones , 2009, DOI: 10.4321/S1576-59622009000100005
Abstract: in this paper, the potential unfairness when using a behavior description interview (bdi) is analyzed. twelve interviewees (6 experienced and 6 inexperienced ones, half of them men and the other half women) were assessed using a bdi. the average scores of participants and the interrater reliability coefficients when using 12 or 6 raters were calculated. statistically significant differences were not found between experienced and inexperienced interviewees, or between male and female ones. the implications of these findings in the use of the bdi for personnel selection processes are discussed.
