    Opis:
    This paper investigates the influence of isolation systems on the seismic behavior of urban reinforce concrete bridge. The performance of the Hesarak Bridge constructed in Karaj city, Iran with two isolation systems; i.e. the existing elastomeric rubber bearing (ERB) and a proposed lead rubber bearing (LRB) is discussed. The numerical model was implemented in the well-known FEM software CSIBridge. The isolated bridge has been analyzed using nonlinear time history analysis method with seven pairs of earthquake records and the results are compared for the two isolation systems. The LRB isolators are shown to have superior seismic performance in comparison with the existing ERB systems based on the response evaluation including force on the isolator, pier base shear, deck acceleration, bending moment, pier displacement, and energy dissipation.

    Opis:
    Collocations are one of the most important elements in language proficiency but the effect of error correction feedback of collocations has not been thoroughly examined. Some researchers report the usefulness and importance of error correction (Hyland, 1990; Bartram & Walton, 1991; Ferris, 1999; Chandler, 2003), while others showed that error correction was of little or no use (Leki, 1990; Truscott, 1996). However, teachers use error correction feedback of collocations most of the time in teaching even though it has not been proven whether there was effect on the improvement of collocation competence of EFL students or not. The researcher tried to investigate the effect of error correction feedback on various categories of lexical collocations (V+N, Adj.+N, N+N), and grammatical collocations (Adj.+Prep.,V+Prep., N) in this study based on Benson, Benson and Ilson's (1986) collocations model. The results revealed that error correction feedback was significant and had a positive effect on the collocation competence at advanced and intermediate levels, but not at the elementary level.

    Opis:
    This study was conducted to evaluate the effects of liquid organic fertilizers (LOFs) and soil moisture status on some biological and physical properties of postharvest soil of maize cultivation. For this purpose, a factorial greenhouse experiment was performed based on the completely randomized design with three replications. Treatments consisted of five levels of LOFs (control, vermicompost tea, vermiwash, plant growth-promoting rhizobacteria [PGPR] enriched vermicompost tea and PGPR enriched vermiwash) and three levels of soil moisture status (field capacity [FC], 0.8 FC and 0.6 FC). The results showed LOFs caused an increase of soil biological properties (soil microbial respiration, soil microbial biomass, dehydrogenase activity and the number of aerobic heterotrophic bacteria) and the improvement of soil physical condition. LOFs increased aggregate stability, hydrophobicity and total porosity, while decreased bulk density and soil penetration resistance. Increasing water stress levels reduced soil biological activity and made soil physical properties more unfavorable. In general, LOFs improved soil conditions by enhancing soil physical and biological properties and decreased the negative effects of water stress. In addition, results showed that LOFs enriched with PGPR could be more effective than non-enriched ones.

    Background. Nanoparticles have been applied worldwide, posing substantial effects on the environment and its living organisms. Plants as sessile organisms are always exposed to considerable fluctuations of nanoparticles concentrations. Here, the effects of different concentrations of bulk and nanosized $Al_2O_3$ on seed germination and seedling growth of Cynara scolymus were investigated in a randomized completely design with four replications. Material and methods. The experimental treatments included four concentrations of bulk $Al_2O_3$ (10, 50, 100 and 500 ppm), four concentrations of nanosized $Al_2O_3$ (10, 50, 100 and 500 ppm), and control without any $Al_2O_3$. Results. The results indicated that among the Cynara scolymus germination indices, only mean germination time and weighted germination index was not affected by treatments. In addition, plumule length, radicle length, seedling fresh and dry weight were affected by bulk and nanosized $Al_2O_3$concentrations, significantly. Radicle length at 50 ppm concentration of nanosized $Al_2O_3$ was higher than those of the untreated control and bulk $Al_2O_3$Al 2O3 at 10, 100 and 500 ppm concentrations. It is concluded that treatment with bulk $Al_2O_3$ treatments have more inhibitory effects on germination indices of Cynara scolymus in comparison to nanosized $Al_2O_3$. Conclusion. Overall, we found through our study that bulk and nano sized $Al_2O_3$ in high concentrations have a negative impact on the seed germination and seedling growth of Cynara scolymus. We saw an overall significant reduction in plumule length, seedling dry biomass, and vigor index of Cynara scolymus seedlings after being exposed to different concentrations of bulk and nano sized $Al_2O_3$, but no significant change in the mean germination time, weighted germination index and radicle length of the seedlings. The two common possibilities are either the bulk and nano sized $Al_2O_3$ will adhere to the roots impeding any uptake of water and nutrients, or that the nanoparticles are up taken and translocated within the plant therefore causing toxicity internally.
    Nanocząstki są stosowane na całym świecie, wywierając znaczny wpływ na środowisko i żywe organizmy. Rośliny jako organizmy ukorzenione są zawsze narażone na znaczne wahania stężeń nanocząstek. Zbadano wpływ różnych stężeń $Al_2O_3$ w masie i nanocząsteczkach na kiełkowanie nasion i wzrost siewek Cynara scolymus w całkowicie losowym projekcie z czterema powtórzeniami. Zabiegi doświadczalne obejmowały cztery stężenia $Al_2O_3$ w masie (10, 50, 100 i 500 ppm), cztery stężenia $Al_2O_3$ w postaci nanocząstek (10, 50, 100 i 500 ppm) oraz kontrolę (bez $Al_2O_3$). Wyniki wskazują, że spośród wskaźników kiełkowania Cynara scolymus zabiegi nie miały wpływu na średni czas kiełkowania i ważony wskaźnik kiełkowania. Na długość pędu embrionalnego, długość korzonków, świeżą i suchą masę siewek istotnie wpływały stężenia $Al_2O_3$ w masie i nanoskali. Długość rodnika przy stężeniu 50 ppm $Al_2O_3$ w postaci nanocząstek była wyższa w porównaniu z kontrolą i masowym $Al_2O_3$ przy stężeniach 10, 100 i 500 ppm. Stwierdzono, że traktowanie dużą ilością $Al_2O_3$ ma bardziej hamujący wpływ na wskaźniki kiełkowania Cynara scolymus niż stosowanie $Al_2O_3$ w postaci nanocząstek. W badaniach określono, że Al2O 3 w dużych ilościach i w wysokich stężeniach nanocząsteczek ma negatywny wpływ na kiełkowanie nasion i wzrost siewek Cynara scolymus. Zaobserwowano znaczne zmniejszenie długości pędu embrionalnego, suchej masy sadzonek i wskaźnika wigoru siewek Cynara scolymus po ekspozycji na różne stężenia $Al_2O_3$ w rozmiarze masowym i nano, ale bez znaczących zmian w średnim czasie kiełkowania, ważonym wskaźniku kiełkowania i długości korzonków siewek. Wynika to albo z przywierania $Al_2O_3$ do korzeni w rozmiarze masowym i nanometrowym, utrudniając wchłanianie wody i składników odżywczych, albo nanocząsteczki są pobierane i przemieszczane w obrębie rośliny, powodując w ten sposób toksyczność wewnętrzną.

    Opis:
    The study was aimed to characterize the antioxidant and anti-microbial activities of Cynodon dactylon with special reference on its precise biochemical analysis. Physiological analysis that total carotenoids content (0.3884 ± 0.0172 mg/g), total chlorophyll content (6.1460 ± 0.2915 mg/g), total phenolic contents (13.4703 ± 0.1494 mg/g), chlorophyll a (3.7708 ± 0.1528 mg/g, catalase (CAT) contents (40.2844 ± 0.1515 units/ mg), total anthocyanin contents (5.0166 ± 0.2966 g–1 FW) total soluble proteins (2.9916 ± 0.1734 mg/g) and total flavonoids content (TFC) (4.7863 ± 0.0442 μg/g) was found higher in the leaves of the Cynodon dactylon whereas, chlorophyll b (2.4881 ± 0.1326 mg/g) was found higher in the stem of Cynodon dactylon, while, peroxidase (POD) contents (81.8763 ± 4.6609 units/mg) and superoxidase dismutase (SOD) activity (80.4346 ± 5.9367 units/mg) was investigated higher in roots of Cynodon dactylon. The anti-microbial activity of Cynodon dactylon extracts was performed using a good diffusion technique against two microbial strains. Among all the plant extracts, the methanolic extracts showed a maximum inhibition zone (26.87 mm) against anti-bacterial strain Escherichia coli whereas n-hexane extract showed a maximum inhibition zone (17.88 mm) against anti-fungal strain Candida albicans. This study reported the antimicrobial activity of Cynodon dactylon against some common pathogens such as Staphylococcus aureus, Escherichia coli, and Candida albicans, which are highly associated with nosocomial infection. From the given results it is concluded that Cynodon dactylon could be exploited in pharmacology due to its antioxidant and anti-microbial properties.

    Opis:
    This study investigates Thomas’ cyclically symmetric attractor dynamics with mathematical and electronic simulations using a proportional fractional derivative to comprehend the dynamics of a given chaotic system. The three-dimensional chaotic flow was examined in detail with Riemann-Liouville derivative for different values of the fractional index to highlight the sensitivity of chaotic systems with initial conditions. Thus, the dynamics of the fractional index system were investigated with Eigenvalues, Kaplan-Yorke dimension, Lyapunov exponent, and NIST testing, and their corresponding trajectories were visualized with phase portraits, 2D density plot, and Poincaré maps. After obtaining the results, we found that the integer index dynamics are more complex than the fractional index dynamics. Furthermore, the chaotic system circuit is simulated with operational amplifiers for different fractional indices to generate analog signals of the symmetric attractor, making it an important aspect of engineering. The qualitative application of our nonlinear chaotic system is then applied to encrypt different data types such as voice, image, and video, to ensure that the developed nonlinear chaotic system can widely applied in the field of cyber security.

    Opis:
    We present the numerical study of unsteady hydromagnetic (MHD) flow and heat trans- fer characteristics of a viscous incompressible electrically conducting water-based nanofluid (containing Al₂O₃ nanoparticles) between two orthogonally moving porous coaxial disks with suction. Different from the classical shooting methodology, we employ a combination of a direct and an iterative method (SOR with optimal relaxation parameter) for solving the sparse systems of linear algebraic equations arising from the FD discretization of the linearized self similar nonlinear ODEs. Effects of the governing parameters on the flow and heat transfer are discussed and presented through tables and graphs. The findings of the present investigation may be beneficial for electronic industry in maintaining the electronic components under effective and safe operational conditions.

    Opis:
    In this paper, the geometric distribution parameter is estimated under a type-I censoring scheme by means of the Bayesian estimation approach. The Beta and Kumaraswamy informative priors, as well as five loss functions are used for this purpose. Expressions of Bayes estimators and Bayes risks are derived under the Squared Error Loss Function (SELF), the Quadratic Loss Function (QLF), the Precautionary Loss Function (PLF), the Simple Asymmetric Precautionary Loss Function (SAPLF), and the DeGroot Loss Function (DLF) using the two aforementioned priors. The prior densities are obtained through prior predictive distributions. Simulation studies are carried out to make comparisons using Bayes risks. Finally, a real-life data example is used to verify the model’s efficiency.
