And Function

Plants seem to be rather defenceless, they are unable to do motion, have no nervous system or immune system unlike animals. Besides this, plants do have hormones, though these substances are produced not in glands. In view of their complexity they lagged behind animals, however, plant organisms show large scale integration in their structure and function. In higher plants, such as in animals, the intercellular communication is fulfilled through chemical messengers. These specific compounds in plants are called phytohormones, or in a wide sense, bioregulators. Even a small quantity of these endogenous organic compounds are able to regulate the operation, growth and development of higher plants, and keep the connection between cells, tissues and synergy beween organs. Since they do not have nervous and immume systems, phytohormones play essential role in plants’ life. Orv. Hetil., 2014, 155(26), 1011–1018.

What Matters

This third volume of this series develops further previous treatment of reasons, normativity, the meaning of moral discourse, and the status of morality. It engages with critics, and shows the way to resolution of their differences. This volume is partly about what it is for things to matter, in the sense that we all have reasons to care about these things. Much of the book discusses three of the main kinds of meta-ethical theory: normative naturalism, quasi-realist expressivism, and non-metaphysical non-naturalism, which this book refers to as non-realist cognitivism. This third theory claims that, if we use the word ‘reality’ in an ontologically weighty sense, irreducibly normative truths have no mysterious or incredible ontological implications. If instead we use ‘reality’ in a wide sense, according to which all truths are truths about reality, this theory claims that some non-empirically discoverable truths — such as logical, mathematical, modal, and some normative truths — raise no difficult ontological questions. This book discusses these theories partly by commenting on the views of some of the contributors to Peter Singer's collection Does Anything Really Matter? Parfit on Objectivity.

Abstract The basic problem of satisfaction of boundary conditions is considered when the generalized stress vector is given on the surfaces of elastic plates and shells. This problem has so far remained open for both refined theories in a wide sense and hierarchic type models. In the linear case, it was formulated by I. N. Vekua for hierarchic models. In the nonlinear case, bending and compression-expansion processes do not split and in this context the exact structure is presented for the system of differential equations of von Kármán–Mindlin–Reisner (KMR) type, constructed without using a variety of ad hoc assumptions since one of the two relations of this system in the classical form is the compatibility condition, but not the equilibrium equation. In this paper, a unity mathematical theory is elaborated in both linear and nonlinear cases for anisotropic inhomogeneous elastic thin-walled structures. The theory approximately satisfies the corresponding system of partial differential equations and the boundary conditions on the surfaces of such structures. The problem is investigated and solved for hierarchic models too. The obtained results broaden the sphere of applications of complex analysis methods. The classical theory of finding a general solution of partial differential equations of complex analysis, which in the linear case was thoroughly developed in the works of Goursat, Weyl, Walsh, Bergman, Kolosov, Muskhelishvili, Bers, Vekua and others, is extended to the solution of basic nonlinear differential equations containing the nonlinear summand, which is a composition of Laplace and Monge–Ampére operators.

The genus Iris Linnaeus (1753: 38), when considered in a wide sense (Mathew 1989, Goldblatt et al. 2008), was established with a total of eighteen species. Presently, it comprises approximately 225 species (Goldblatt et al. 1998), distributed mostly in temperate regions of the Northern Hemisphere.

Clear Idea

The task of our science of medicine, to put it briefly, is to heal the suffering man; but this simple and briefly expressed task is extremely difficult, extremely responsible, and the possibility of its fulfillment is achievable only with the satisfaction of certain well-known requirements. Among these requirements, it is necessary to mention the desire to establish an understanding of the average normal human organism, a clear idea of ​​normal individual deviations, the study of conditions that are conducive not only to the preservation, but also to the prosperity of these two types of life in the study of the wide sense of the causes of this organism; hence the need to establish an understanding of "diseases", their types, signs, reasons in each individual case ...

Linked and maximal linked systems (MLS) on π -systems of measurable (in the wide sense) rectangles are considered (π-system is a family of sets closed with respect to finite intersections). Structures in the form of measurable rectangles are used in measure theory and probability theory and usually lead to semi-algebra of subsets of cartesian product. In the present article, sets-factors are supposed to be equipped with π-systems with “zero” and “unit”. This, in particular, can correspond to a standard measurable structure in the form of semialgebra, algebra, or σ-algebra of sets. In the general case, the family of measurable rectangles itself forms a π -system of set-product (the measurability is identified with belonging to a π - system) which allows to consider MLS on a given π -system (of measurable rectangles). The following principal property is established: for all considered variants of π -system of measurable rectangles, MLS on a product are exhausted by products of MLS on sets-factors. In addition, in the case of infinity product, along with traditional, the “box” variant allowing a natural analogy with the base of box topology is considered. For the case of product of two widely understood measurable spaces, one homeomorphism property concerning equipments by the Stone type topologies is established.

The Difference

This chapter gives an overview of how Byzantines conceptualized “poetry.” It argues that from the Byzantine point of view, poetry only differs from prose in a very formal way, namely that it is written in verse. Both prose and poetry belonged to the category of logoi, the only label that was very frequently used, in contrast to the term “poetry,” which was reserved for the ancient poetry studied at schools. Many authors considered (and exploited) the difference between their own prose texts and poems as a primarily formal one. Nevertheless, poetry did have some functions that set it apart from prose, even if these features are for us less expected. The quality of “bound speech” gained a spiritual dimension, since verse was seen as a restrained form of discourse, also from a moral point of view. Finally, the chapter gives a brief overview of the social contexts for which (learned) poetry was the medium of choice: as an inscription, as paratext in a wide sense, as a piece of personal introspection, as invective, as summaries (often of a didactic nature), and as highly public ceremonial pieces.
