This paper investigates the nonlinear vibration of saturated porous functionally graded plate subjected to the combination of mechanical and thermal loadings. Three different distributions of porosity are considered. Based on the Biot and higher order shear deformation theories, the vibration characteristics including natural frequency, deflection amplitude – time curves and relation between frequency ratio and amplitude of the saturated porous plate are determined.

This article is to show how risk can be managed in the transport business according to the ISO 31000:2018 risk management model. The method used in the research article is comparison, evaluation and application. Risk management as well as handling of each crisis situation has its own and unique nature, associated with different circumstances, implemented in different conditions and associated with different event contexts. The resolution of each crisis situation requires practical experience and special expertise in different fields.

In relational and object-oriented database systems, fuzzy or uncertain data will always be naturally present. However, these systems have many limitations for handling complex data types of fuzzy nature. Therefore, to represent and process fuzzy data, they need a flexible and efficient fuzzy query system. To solve this challenge, this paper proposes two different approaches to increase the flexibility of the fuzzy interrogation system.

Endocrine conditions requiring surgical intervention in the pediatric age­ group are uncommon. When diagnosed, they are the source of great in­ terest and, often, considerable debate. This is understandable, since few centers and even fewer individual surgeons can draw on vast experience of this subject. The great divergence of opinion regarding management is also understandable in that pediatric endocrine lesions often differ considerably from their adult counterparts in histology, natural history and response to treatment.

Any technological advance, innovation or economic growth created by an organization is dependent on how that organization's culture and environment fosters or inhibits these developments. This process is further complicated by the global nature of economic activity and differences in national cultures due to country-specific histories, experiences, traditions and rules. The distinguished authors in this important new book aim to study the nature of organizational innovation and change by examining the complex interplay between entrepreneurship, innovation and culture.

In this study, we used the reliable GC-FID/MS technique to analyze the methyl ester derivatives of 37 different kinds of fatty acids. The results showed that high saturated fat concentration in all samples was mostly palmitic acid, whereas the low unsaturated fatty acid content in the cis form was primarily oleic acid and linoleic acid. The amount of monounsaturated and polyunsaturated fats is quite low.

Jasminum binhchauense, a new species of the family Oleaceae, is described and illustrated. The species was collected during 2022–2023 from Binh Chau-Phuoc Buu Nature Reserve, Ba RiaVung Tau province, southern Vietnam. The new species differs from its congeners in its branchlets, leaf blade, petioles and calyx. A taxonomic description, a table comparing morphological characters of the allied species, and illustrations, a color photo-plate are provided.

The derived temperature dependences of the peak intensities, separations and half-widths of the separate spectral peaks in the A-band phonon progressions indicate the different trends for vibration-free zero-phonon electronic transition and vibration-related lower-energy electronic transitions to high vibrational levels of the ground electronic state – lower thermal damping and more softened phonon for the zero-phonon transition, also implying the extended defect origin of the A-band photoluminescence.

In ebook "Developmental biology of neoplastic growth" tumour growth is perceived as a deviation from the normal development of the human organism. The molecular, cellular, and tissue determinants of different tumours are discussed showing that each is a different disease, often corresponding to a particular developmental stage. The natural history of several cancers illustrates how clinical incidence can be just the visible part of the iceberg, while the first changes at the tissue level sometimes occur several years before tumour growth becomes manifest.

Ebook "Chemistry of polymeric metal chelates" deals with the chemistry of polymeric metal chelates. The main results and the production and chemical structure of polymers with chelate units as well as the specificity of metal complex binding of different structure are presented here. This book also reveals the transformations which components undergo in the course of chelation. Special attention is paid not only to synthetic but also to natural (including living) systems. The usage of polymeric metal chelates and their development are examined.
