ArcStereoNet is a new ArcGIS® based toolbox for stereographic projections that we implement here using Python 2.7 programming language. The reason to develop another stereographic projection package arises from the recent use of Python as an exclusive programming language within the ArcGIS® environment. This permits a more flexible approach for the development of tools with very intuitive GUIs, and also allows the user to take full advantage of all potential GIS mapping processes. The core of this new projections toolbox is based on the capability to easily apply and compare most of the commonly used statistical methods for cluster and girdle analysis of structural data. In addition to the well-known Fisher, K-means, and Bingham data elaborations, a completely new algorithm for cluster analysis and mean vector extraction (Mean Extractor from Azimuthal Data), was developed, thereby allowing a more reliable interpretation of any possible structural data distribution. Furthermore, as in any other GIS platform, users can always precisely correlate each single projected data point with the corresponding geographical/locality position, thereby merging or subdividing groups of structural stations with a simple selection procedure. ArcStereoNet also creates rose diagrams, which may be applied not only to fault/joint planes orientation data, but also for the analysis of 2D microstructural fabric parameters. These include geometrical datasets derived from the minimum bounding approach as applied to vectorized grains in thin sections. Finally, several customization settings ensure high-quality graphic outputs of plots, that also allow easy vector graphics post-processing.

Abstract. We present measurements of crystal c-axis orientations and mean grain area from the Dome Summit South (DSS) ice core drilled on Law Dome, East Antarctica. These data are from 185 individual thin sections obtained between a depth of 117 m below the surface and the bottom of the DSS core at a depth of 1196 m. The median number of c-axis orientations recorded in each thin section was 100, with values ranging from 5 through to 111 orientations. The data from all 185 thin sections are provided in a single comma separated value (csv) formatted file which contains the c-axis orientations in polar coordinates, depth information for each core section from which the data were obtained, the mean grain area calculated for each thin section and other data related to the drilling site. The data set is also available as a MATLAB™ structure array. Additionally, the c-axis orientation data from each thin of the 185 thin sections are summarised graphically in figures containing a Schmidt diagram, histogram of c-axis colatitudes and rose plot of c-axis azimuths. All of these data are referenced by doi:10.4225/15/5669050CC1B3B and are available free of charge at https://data.antarctica.gov.au.

The crystalloid core in peroxisomes of the methylotrophic yeast Hansenula polymorpha is composed of the octameric flavoprotein methanol oxidase (MOX). We transformed yeast cells with a high-copy-number vector harboring the cloned MOX gene in order to study the effects on regulation, protein import, and peroxisome biosynthesis. In transformed wild-type cells, no increase in expression of MOX was detectable. Mutants defective in MOX activity were isolated by a specific selection procedure. Two structural MOX mutants are described that allow overproduction of a fully active enzyme upon transformation at quantities of about two-thirds of the total cellular protein. The overproduced protein was imported into peroxisomes, altering their morphology (in thin sections) and stability in cell lysates; the organelles showed a tendency to form rectangular bodies, and their lumina were completely filled with the crystalloid structure. The overall size of the peroxisomes was increased severalfold in comparison with the size of nontransformed yeast cells. The results suggest high capacities of peroxisomal growth conferred by overproduction and import of a single protein.

AbstractA study of c-axis orientations in the upper 1500m of the Dome C (East Antarctica) deep ice core has been carried out using an automatic ice-fabric analyzer (AIFA). Twenty-nine vertical and a few horizontal thin sections from different depths in the core have been analyzed. Several statistical parameters describing fabric strength and fabric shapes have been calculated from the c-axis orientation data. The fabric diagrams display a near-random c-axis orientation distribution in the uppermost parts of the ice sheet. A tendency of c-axis rotation towards a broad single-maximum fabric is observed in the lowest part of the studied interval. The fabric development at Dome C thus appears typical for ice-sheet summit and dome sites. The fabric development at Dome C is compared with the fabric evolution in the Dome F and GRIP ice cores, and data on crystal size obtained with image-analysis techniques are presented. Studies of misorientation angles between the c axes of neighbouring crystals reveal little evidence for polygonization, but microscopic observations show that sub-grain boundaries are present in half of the grains at any depth.

AbstractThe fabric of polycrystalline ice is typically described using the c-axis orientation alone, but this is insufficient for a full description of grain orientations in this hexagonal material. Electron backscatter diffraction (EBSD) provides full c- and a-axis orientation of individual grains, and is used here to study Greenland Ice Sheet Project 2 (GISP2) ice specimens from depths of 1551, 1642 and 1745 m. Complete orientation data are used to compare nearest-neighbor relationships to overall fabric and to differentiate between recrystallization mechanisms. Changes in orientation between grains and subgrains in GISP2 specimens were correlated with the appearance of grain boundaries on thin sections and used to identify grain sets that were probably produced by polygonization. Comparison of grain misorientations that take into account both c- and a-axis differences with those derived from c-axis directions alone reveals the presence of polygonization and illustrates the usefulness of this technique.

Electron microscopy of the filamentous gliding marine bacterium Flexibacter polymorphus demonstrated that the cell envelope consists of an electron-dense intermediate layer located between two unit-type membranes: an outer membrane, presumably of lipopolysaccharide, and an inner cytoplasmic membrane. Separation of living filaments into single cells by lysozyme suggests that a peptidoglycan moiety, possibly corresponding to the intermediate layer, might be situated between the two membranes. Cell division proceeds by invagination of the cytoplasmic membrane and intermediate layer forming a transverse septum. Cells generally fail to separate after the division process, so that a common outer membrane encloses all of the cells in a single filament.There is a continuous layer of macromolecular cup-shaped elements ('goblets') attached to the outermost surface of the lipopolysaccharide membrane. Tangential thin sections, as well as negatively stained preparations of envelope fragments (produced by sonication of autolyzed cells), showed that the goblets are arranged in a close-packed hexagonal array. The presence of electron-dense structures located between the outer and inner membranes, and exhibiting the same periodicity as the goblets, suggests that some part of the goblets penetrates the outer membrane and extends across the periplasmic space to the dense intermediate layer or cytoplasmic membrane. Spontaneous autolysis in aging cultures is accompanied by the formation and release into the culture medium of large numbers of outer membrane vesicles coated with goblets. A tentative reconstruction of the envelope of F. polymorphus, based on the fine-structural data, is presented.

Purpose. Investigate the national component and stylistic features of satirical graphics of P. Kovzhun and E. Kozak in popular Lviv humorous magazines of the interwar period. Methodology. The applied art analysis makes it possible to investigate, identify, compare and describe the features of satirical graphics and artistic design of Lviv humorous publications of the interwar period. Comparative and historical methods help to trace the work of leading artists in Lviv satirical periodicals of 20–30s years of XX century. Results.Stylistic features of satirical graphics by P. Kovzhun and E. Kozak in Lviv humorous magazines of 20–30s years of the XX century are determined. It is noted that the artistic style of these artists was influenced by Western European art trends, such as: modernism, expressionism, cubism, futurism. In their graphics, cartoonists use similar tools to achieve a greater effect – grotesque, allegory, zoomorphism. It is traced that each of these artists had his own individual style of satirical illustration, which was supported by national motives. The article draws parallels between German and Lviv satirical magazine graphics on the example of the magazine "Simplicissimus". It was found out that P. Kovzhun and E. Kozak, as leading artists of humorous publications, in addition to highly artistic illustrations, made high-quality graphic design for the magazines «Maski», «Zyz», «Komar». The artistic design of the covers and technical features of these publications are analyzed. Most satirical magazines had a symmetrical hierarchical composition of the title page with a limited polychrome palette. The logo-name on the cover of the magazine was harmoniously perceived together with the title illustration. The cover was made in color, usually in two colors, magazine covers were monochrome. The semantic load of visual satirical material in humorous editions of the interwar period is established. Scientific novelty. The satirical graphics with an emphasis on the national component of the leading illustrators P. Kovzhun and E. Kozak in Lviv humorous magazines of 20–30s years of the XX century is investigated and compared. The peculiarities of the design of the covers of popular Lviv satirical editions of the interwar twentieth century, such as «Maski», «Zyz», «Komar» are determined. Practical significance. Given data on satirical graphics in Lviv magazines of the 20–30s of the XX century and their artistic design will help in understanding the traditions of Ukrainian Galician satirical illustration and magazine design.
