It was demonstrated that even though the mean values of hydroxyproline within the experimental groups were higher than the respective control groups, no statistical significance could be attributed to this observation.

Повний текст джерелаCorrosion resistance and soldering tendency of different materials in moltenAl–Si–Cu alloy were studied. Hot-working tool steel, plasma nitrided steel andduplex layers with CrN, TiAlN, TiAlSiN and CrAlN top coatings, which wereproduced to various degree of surface roughness, were covered by the study.An ejection test was employed for investigation of the concerned phenomena.The ejection test was improved in order to increase its accuracy and thereliability of process simulation. Samples were examined in both short andextended periods of contact (5 and 20 min) with liquid casting. Castingsolidification was extended in order to intensify the corrosion effects. Contraryto common findings, it was found that the ejection force of the investigatedmaterials does not depend on their chemical composition. For the coatedsamples, a pronounced dependence of the ejection force on the surfaceroughness was found. The ejection force increases with decrease in surfaceroughness. All investigated coatings are prone to mechanical soldering by Al–Si–Cu alloy. Still, their corrosion resistance substantially exceeds the corrosionresistance of steel and plasma nitrided layer. Longer exposure of coatedsamples to cast alloy induced lower ejection forces, which is a consequenceof coatings oxidation. It was found that the investigated coatings are inert toliquid aluminium. However, the underlying material undergoes oxidation andcorrosion through coating growth defects. The findings concerning the wearmechanisms of protective layers support further development of duplex layersintended for die casting tools protection.

The photo captured by the camera is often different from what we see due to the limited dynamic range of the camera sensors. To produce an image with true luminance, the high dynamic range (HDR) image capturing technique is a good solution. It provides a wider dynamic range than the traditional techniques, and is able to re-produce the luminance with high fidelity. This work proposes an adaptive high dynamic range image fusion algorithm. By utilizing the exposure curve characteristics of image sensors and the exposure parameters of each image, it can convert the actual luminous intensity into image data with high accuracy. This method can extend the linear range of the luminous intensity by effectively fusing images with different exposures. The luminance processing is based on the principle of preserving the image information so as to re-produce the true luminous distribution of the image. In addition, the edge information is also kept with the propose method. The simulation results show that the proposed algorithm is able to reach wide system dynamic range. Both objective and subjective measures show superior performance compared with existing methods. With different capturing environments, it generally produces high dynamic range images with better performance of details and contrast in both bright and dark areas.

Повний текст джерелаA linha celular contínua BEAS-2B, derivada de células epiteliais brônquicas humanas normais, foi estabelecida em 1988, pelo grupo de Curtis C. Harris, como um modelo in vitro do epitélio brônquico normal, para o estudo da carcinogénese pulmonar.De igual maneira às células de outras linhas celulares contínuas, as células BEAS-2B sofrem variações genéticas e fenotípicas quando cultivadas in vitro por longos períodos de tempo, nomeadamente ao nível da expressão genética e morfologia. Estas variações podem explicar, pelo menos em parte, as inconsistências encontradas na literatura em estudos que utilizaram esta linha celular. Mais importante, a linha celular alterada pode deixar de ser um modelo confiável do material original.O primeiro objetivo de presente estudo foi caracterizar ainda mais os efeitos das passagens sucessivas no fenótipo da linha celular BEAS-2B, nomeadamente no conteúdo proteico, taxa de produção de lactato, capacidade migratória, resposta ao stress e resistência a concentrações levemente citotóxicas de dicromato de potássio, um agente carcinogénico pulmonar. Observámos que duas destas características (resposta ao stress e taxa de produção de lactato) variaram significativamente ao longo do tempo em cultura. Em conjunto, as nossas observações e as de outros sugerem que o grau de transformação desta linha celular muda com as passagens extensivas.O segundo objetivo do presente trabalho foi avaliar o impacto da exposição prolongada a uma leve concentração citotóxica de Cr(VI) em várias características da linha celular BEAS-2B, nomeadamente na morfologia e padrão de crescimento, taxa de crescimento, potencial clonogénico e resistência a Cr(VI). Concluímos que a exposição ao Cr(VI) por vários meses afetou a morfologia e o padrão de crescimento da linha celular BEAS-2B e diminuiu as suas taxas de crescimento. Por outro lado, não foram observadas diferenças significativas no potencial clonogénico e na resistência ao Cr(VI).
The BEAS-2B continuous cell line, derived from normal human bronchial epithelial (NHBE) cells, has been established in 1988, by the group of Curtis C. Harris, as an in vitro model of normal bronchial epithelium, for the study of lung carcinogenesis.Similar to cells from other continuous cell lines, the BEAS-2B cells are known to undergo genetic and phenotypic variations when grown in vitro over extended periods of time, namely at the level of gene expression and morphology. These variations might explain, at least partly, inconsistencies found in the literature in studies conducted using this cell line. Importantly, the altered cell line may no longer be a trustworthy model of the original material.The first aim of the present study was to further characterize the effects of extended passaging on the phenotype of the BEAS-2B cell line, namely in terms of protein content, rate of lactate production, migratory capacity, stress response and resistance to mildly cytotoxic concentrations of potassium dichromate, a lung carcinogen. We found that two of these traits (stress response and rate of lactate production) changed significantly over time in culture. Altogether, our observations and those of others suggest that the degree of transformation of this cell line changes upon extensive passaging.The second aim of the present study was to assess the impact of a prolonged exposure to mildly cytotoxic concentration Cr(VI) on several traits of the BEAS-2B cell line, namely their morphology and pattern of growth, growth rate, clonogenic potential and resistance to Cr(VI). We found that exposure to Cr(VI) for several months changed the morphology and the growth pattern of the BEAS-2B cell line and decreased its growth rates. On the other hand, no significant changes were observed in terms of clonogenic potential and resistance to Cr(VI).

Facing the variety of consumer’s demand nowadays, firms develop market in different segments. Firms operate market by using different ways as well as different types of information exposure. However, what are consumers’ response to the exposure of information? Do the perceived values of consumers be influenced by the extends of different information exposure? These topics are really worth study. This study, which is the first try, integrate 3 constructs of information exposure, the information exposure content, the information exposure volume and the information exposure frequency in consist of the extend of information exposure. Try to measure and to explicit the relationship between the extend of information exposure and consumers perceived values by adopting varies of products categories and products involvements as moderators. Random samples are selected from individual consumers, located at Taipei city and Taipei county, and reached a total of 1205 valid questionnaires. The results of this study support the hypothesis that the degree of exposure content is related positively to the degree of influence in consumers perceived values. Whereas, the degree of exposure frequency and exposure volume are unrelated to consumers perceived values. However, the products categories have significant difference between information exposure and consumers perceived value. In addition, the results indicate a significant positive association between the information exposure and consumers perceived value in consumers incomes.. On the contrary, it also indicates that a significant negative association between the information exposure and consumers perceived values in consumers educational backgrounds. Therefore we suggest that a firm should persuade consumers of different levels into objective products in different ways besides a firm should fully disclose the information if the objective product is superior on that attribute.
