    Opis:
    Elevated water tanks in an empty condition, though not important in structural design, becomes an important problem in seismic design. The objective of the present research is to investigate the elevated water tanks in empty and in filled conditions and to emphasize the importance of seismic response. Four elevated tanks with various parameters are selected for seismic analysis with the base isolation technique. It is found out that empty tanks are highly vulnerable to earthquake effects, whereas filled tanks can be mitigated by providing base isolation. A simple experimental investigation has also been carried out to validate the analytical results.

    Opis:
    The structural concept of the dome dates back to the Pantheon in Rome. It is used as the cover of many churches and mosques all around the world. Light solutions, with a well-visible dome-shaped truss skeleton, are often preferred in modern architecture. Base isolation techniques can be adopted to mitigate the seismic effects. This paper aims to investigate the efficiency of different designs for the truss skeleton. To solve the problem, one has to assign the constraints, the materials and the geometry of the dome, its supporting structure and the isolation devices (number, locations, and type). The screening of the effects of different scheme assumptions on structural behaviour provides a better insight into the problem.

    Opis:
    Candida albicans is a major human fungal pathogen especially as an etiologic agent of opportunistic oral and genital infections. Moreover, C. albicans can be involved in the deep infections and recent evidence suggests that the majority of diseases produced by this pathogen are associated with biofilm growth. The aims of this study were to evaluate biofilm production ability of C. albicans strains isolated from different sources, and to evaluate the effect of serum for enhancement the growth of biofilm. The strains used in this study were obtained from three sources; 12 from feces of patients with gastrointestinal disturbances, 13 from the oral cavity of patients with oral candidiasis, and 16 from the vagina of patients with Candida vulvovaginitis (CVV). Polystyrene 96-well plates were used to grow biofilms and crystal violet (CV) staining method was used to evaluate the growth. There were no differences in biofilm growth expressed as CV absorbance between C. albicans strains from different origins neither in Yeast Nitrogen Base broth (YNB) or in bovine serum (BS) (ANOVA, P=0.1648, P=0.5106, respectively). In the BS, the biofilm production was greater than in YNB medium for all samples (ANOVA, P=0.0003).
