This article introduces the notion of pleasant musical imagery (PMI) for denoting everyday phenomena where people want to cherish music “in their heads.” This account differs from current paradigms for studying musical imagery in that it is not based a priori on (in)voluntariness of the experience. An empirical investigation of the structure and experiential content in 50 persons’ experiences of PMI applied the elicitation interview method. Peer judgments of the interviews helped to bridge a phenomenological investigation of particular experiences with systematic between-subjects analysis. Both structural features of the imagery (e.g., Looseness of structure or Looping) and content features of the imagery (e.g., Embodied evocativeness and Object-directedness) showed significant associations with participants’ individual characteristics, personality, and/or cognitive style. The approach taken suggests a new paradigm for studying musical imagery—one that is based on tracing the interactional and enactive processes of “inner listening.”

Subjective Well Being

The article analyzes the basic theory of subjective well-being. It is indicated that the desire for well-being is one of the main driving forces of human society, its subjective feeling is an important condition for a full-fledged life of a person, therefore, attention is drawn to the need for psychological research related to the analysis of methodological and systemic approaches aimed at studying subjective well-being. The main differences between the theories, as well as the relationship between the concepts of "well-being", "subjective well-being" and "psychological well-being" are shown, a theoretical analysis of existing modern approaches to the problem of studying subjective well-being and its components is carried out. Subjective well- being is considered as an integral psychological formation, including the assessment and attitude of a person to his life and himself. The main approaches to elucidating the components of subjective well-being are characterized – hedonistic and eudemonistic. Based on the analysis of modern and research, a study of its sources and determinants is carried out, the component composition, terminology base is clarified, the influence of various factors, such as: social relations, genetic predisposition, material well-being, joy of needs, existence of goals and meaning of life, physical activity are investigated , individual characteristics, accepting oneself as a person, etc. Through a synthesis of various approaches to understanding subjective well-being, several key statements have been identified in the framework of the study: the positivity of measuring well-being as the presence of positive intensity indicators and experiences of different intensities; global dimension – the interconnection of all aspects of human life (social, biological, psychological, physical) time lag, dynamism; subjectivity as the dependence of the experience of well-being on assessment, attitude and personal experience. Attention is drawn to the fact that the term "subjective well-being" is interdisciplinary and has its meaning in psychology, sociology, economics and the political sciences. The prospect of further research is seen in continuing to study the structural features of models and components of well-being.

Commercial polyimide films have shown to be homogeneous on a scale of 5 to 200 nm. The observation of Skybond (SKB) 705 and PI5878 was carried out by using a Philips 400, 120 KeV STEM. The objective was to elucidate the structural features of the polymeric samples. The specimens were spun and cured at stepped temperatures in an inert atmosphere and cooled slowly for eight hours. TEM micrographs showed heterogeneities (or nodular structures) generally on a scale of 100 nm for PI5878 and approximately 40 nm for SKB 705, present in large volume fractions of both specimens. See Figures 1 and 2. It is possible that the nodulus observed may be associated with surface effects and the structure of the polymers be regarded as random amorphous arrays. Diffraction patterns of the matrix and the nodular areas showed different amorphous ring patterns in both materials. The specimens were viewed in both bright and dark fields using a high resolution electron microscope which provided magnifications of 100,000X or more on the photographic plates if desired.

Insight Into

Echinodermata is a phylum of marine invertebrates which has been extant since Cambrian time (c.a. 500 m.y. before the present). Modern examples of echinoderms include sea urchins, sea stars, and sea lilies (crinoids). The endoskeletons of echinoderms are composed of plates or ossicles (Fig. 1) which are with few exceptions, porous, single crystals of high-magnesian calcite. Despite their single crystal nature, fracture surfaces do not exhibit the near-perfect {10.4} cleavage characteristic of inorganic calcite. This paradoxical mix of biogenic and inorganic features has prompted much recent work on echinoderm skeletal crystallography. Furthermore, fossil echinoderm hard parts comprise a volumetrically significant portion of some marine limestones sequences. The ultrastructural and microchemical characterization of modern skeletal material should lend insight into: 1). The nature of the biogenic processes involved, for example, the relationship of Mg heterogeneity to morphological and structural features in modern echinoderm material, and 2). The nature of the diagenetic changes undergone by their ancient, fossilized counterparts. In this study, high resolution TEM (HRTEM), high voltage TEM (HVTEM), and STEM microanalysis are used to characterize tha ultrastructural and microchemical composition of skeletal elements of the modern crinoid Neocrinus blakei.

Different Cell Types

Various types of intermediate-sized (10-nm) filaments have been found and described in many different cell types during the past few years. Despite the differences in the chemical composition among the different types of filaments, they all yield common structural features: they are usually up to several microns long and have a diameter of 7 to 10 nm; there is evidence that they are made of several 2 to 3.5 nm wide protofilaments which are helically wound around each other; the secondary structure of the polypeptides constituting the filaments is rich in ∞-helix. However a detailed description of their structural organization is lacking to date.

Identical Unit

Highly ordered or crystalline biological macromolecules become severely damaged and structurally disordered after a brief electron exposure. Evidence that damage and structural disorder are occurring is clearly given by the fading and eventual disappearance of the specimen's electron diffraction pattern. The fading and disappearance of sharp diffraction spots implies a corresponding disappearance of periodic structural features in the specimen. By the same token, there is a oneto- one correspondence between the disappearance of the crystalline diffraction pattern and the disappearance of reproducible structural information that can be observed in the images of identical unit cells of the object structure. The electron exposures that result in a significant decrease in the diffraction intensity will depend somewhat upon the resolution (Bragg spacing) involved, and can vary considerably with the chemical makeup and composition of the specimen material.

Human And Mouse

Metaphase chromosomes from human and mouse cells in vitro are isolated by micrurgy, fixed, and placed on grids for electron microscopy. Interpretations of electron micrographs by current methods indicate the following structural features.Chromosomal spindle fibrils about 200Å thick form fascicles about 600Å thick, wrapped by dense spiraling fibrils (DSF) less than 100Å thick as they near the kinomere. Such a fascicle joins the future daughter kinomere of each metaphase chromatid with those of adjacent non-homologous chromatids to either side. Thus, four fascicles (SF, 1-4) attach to each metaphase kinomere (K). It is thought that fascicles extend from the kinomere poleward, fray out to let chromosomal fibrils act as traction fibrils against polar fibrils, then regroup to join the adjacent kinomere.
