Opis:
One of the ways to reduce the water consumption by plants while maintaining their proper quality is to use substances that limit excessive transpiration. Three preparations at following concentrations: Moisturin (10%), Root-Zone (4.5%) and Vapor Gard (1%), were used in the experiment. Moisturin and Vapor Gard were applied in the form of a single spray, and Root-Zone as a single irrigation in mid July.The aim of the research was to assess the effect of several anti-transpirants on some biometric features of the ‘Tardiva’ panicled hydrangea depending on the frequency of irrigation. The following parameters were measured: area, perimeter, width and length of leaf blade, length and width of inflorescences, and the diameter of shoots. Treatment of H. paniculata cv. ‘Tardiva’ with Root-Zone and Moisturin anti-transpirants with a single irrigation every other day allows to reduce the water consumption and obtain shrubs of a quality comparable with plants irrigated twice a day. The use of Moisturin with a twice daily irrigation positively affected the length and width of inflorescences.

Opis:
Purpose: In this study, the free vibration analysis of functionally graded materials (FGMs) sandwich beams having different core metals and thicknesses is considered. The variation of material through the thickness of functionally graded beams follows the power-law distribution. The displacement field is based on the classical beam theory. The wide applications of functionally graded materials (FGMs) sandwich structures in automotive, marine construction, transportation, and aerospace industries have attracted much attention, because of its excellent bending rigidity, low specific weight, and distinguished vibration characteristics. Design/methodology/approach: A mathematical formulation for a sandwich beam comprised of FG core with two layers of ceramic and metal, while the face sheets are made of homogenous material has been derived based on the Euler–Bernoulli beam theory. Findings: The main objective of this work is to obtain the natural frequencies of the FG sandwich beam considering different parameters. Research limitations/implications: The important parameters are the gradient index, slenderness ratio, core metal type, and end support conditions. The finite element analysis (FEA), combined with commercial Ansys software 2021 R1, is used to verify the accuracy of the obtained analytical solution results. Practical implications: It was found that the natural frequency parameters, the mode shapes, and the dynamic response are considerably affected by the index of volume fraction, the ratio as well as face FGM core constituents. Finally, the beam thickness was dividing into frequent numbers of layers to examine the impact of many layers' effect on the obtained results. Originality/value: It is concluded, that the increase in the number of layers prompts an increment within the frequency parameter results' accuracy for the selected models. Numerical results are compared to those obtained from the analytical solution. It is found that the dimensionless fundamental frequency decreases as the material gradient index increases, and there is a good agreement between two solutions with a maximum error percentage of no more than 5%.

Opis:
Here, we report the unusual behavior shown by the PbS samples prepared using a multilayer deposition approach by chemical solution deposition method. Thin samples were prepared by depositing several films at different deposition conditions on glass substrates. X-ray diffraction showed that final multilayer samples showed a peculiar variation. Even when they showed well defined structure the intensities of the peaks do not correspond to those of the initial films.
