Journalists in Switzerland : structures and attitudes revisited

It is often stated that journalism and the media are going through some fundamental changes. In this article, we present a description of the journalists in Switzerland, based on a nation-wide survey conducted in 2015. This data gives a quantitative description of journalists in Switzerland. Furthermore, this article makes comparison between various groups of journalists, for example between the different language regions in Switzerland, in order to give a differentiated picture of who the journalists are, what their working situation looks like and how they perceive their own professional role in society

Application of Scanning Electron Microscopy to the Study of Shark Dermal Denticles

Clear, high resolution scanning electron micrographs of shark dermal denticles are essential to allow the study of their morphology and micro-relief. Various techniques were tried to remove mucus and adventitious debris, including KOH, trypsin enzyme, and ultrasonication. In most species examined the best results were obtained with enzyme treatment followed by ultrasonication. For scanning electron microscopic examination it was found that 15 nm gold coating, or more, and 10 kV, or less, had to be employed to reduce charging of the denticles

Elemental and Ultrastructural Characteristics of the Egg Capsules of Nautilus Pompilius

Six pearly nautili (Nautilus pompilius) raised in captivity produced nonviable egg capsules which were examined using scanning electron microscopy ( SE M) and energy dispersive x-ray spectrometry (EDS). Macro and microscopic observations revealed two distinct and separate walls encircling the yolk sac. Both walls exhibited a porous appearance in cross-section. Protein analysis demonstrated the proteinaceous nature of nidimental gland secretions and egg capsule walls. EDS analysis of each wall shows the elemental composition to be identical in both, with each wall containing similar proportions of S, CI, Mg, Na, K, and trace amounts of Ca. X-ray mapping of Na and Cl along each wall surface suggests similar construction of both walls. EDS analysis of the nidimental gland secretions of the adult female nautilus have shown a composition similar to that of the egg capsule

Family Hemiscyllidae

93 p. : ill., maps ; 26 cm.Includes bibliographical references (p. 91-93)."The genera Hemiscyllium and Chiloscyllium and their species are revised, and two new species of Chiloscyllium are described. Hemiscyllium includes five species: H. freycineti, H. hallstromi, H. ocellatum, H. strahani, and H. trispeculare. One juvenile specimen cannot be assigned to species and differs from all known juveniles. It may represent a new species, but adults must be acquired before this can be conclusively shown. Chiloscyllium includes seven species: C. burmensis, new species, C. confusum, new species, C. hasselti, C. griseum, C. indicum, C. punctatum, and C. plagiosum. Skeletal anatomy and dermal denticles are studied and described for all species. A scheme of interrelationships within the family is proposed. The family Hemiscyllidae and the included genera of Hemiscyllium and Chiloscyllium are shown to be monophyletic"--P. 3
