A study of the species of Entyloma on North American composites suggests that almost every form can be assigned to one of two phyletic groups. E. polysporum contains most of the forms with densely crowded, rather large teliospores and no conidia. E. Davisii on Rudbeckia hirta and, probably, a fungus on Lepachys columnaris are segregated from it. E. Compositarum contains most of the forms with smaller, uncrowded spores and abundant conidia. E. arnicale and possibly one or two other forms may be regarded as segregates from this species.Emended descriptions of E. polysporum and E. Compositarum are given to clarify the differences between these two species. Corrections are also made in the identification of some exsiccati specimens.Comparisons are made with European forms to the extent that material has been available, but far more study of European specimens is needed to allow assessment of some species.Species concepts for these fungi are discussed, and criteria are suggested for adequate morphological studies.

Limnological Parameters

The Cenote Jennifer is an important and unique aquatic sinkhole in Cayo Coco (Jardines del Rey Tourist Destination) that has brackish to saline water. Two samplings were made in 1998 and 2009, and 4 metabolism community experiments in 2009. Some limnological parameters were measured in both samplings (temperature, salinity, pH, dissolved oxygen major ions, hydrogen sulfide, nutrients and others). Community metabolism was measured through incubated oxygen concentration in clear and dark oxygen bottles. Results showed that the sinkhole limnology depends on rainfall and light incidence year, with some stratification episodes, due to halocline or oxycline presence, rather than thermocline. The sinkhole water was oligotrophic (total nitrogen of 41.5 ± 22.2 μmol l−1 and total phosphorus of 0.3 ± 0.2 μmol l−1) and with low productivity (gross primary productivity of 63.0 mg C m−2 d−1). Anoxia and hypoxia were present at the bottom with higher levels of hydrogen sulfide, lower pH and restricted influence of the adjacent sea (2 km away). To protect the Cenote Jennifer, tourist exploitation should be avoided and more resources to ecological and morphological studies should be allocated, and eventually use this aquatic system only for specialized diving. For conservation purposes, illegal garbage disposal in the surrounding forest should end.

Peanut allergens are both stable and potent and are capable of inducing anaphylactic reactions at low concentrations. Consequently, the consumption of peanuts remains the most common cause of food-induced anaphylactic death. Since accidental exposure to peanuts is a common cause of potentially fatal anaphylaxis in peanut-allergic individuals, we tested for the presence of peanut protein in chocolate bars produced in Europe and North America that did not list peanuts as an ingredient. Ninety-two chocolate bars, of which 32 were manufactured in North America and 60 were imported from Europe, were tested by the Veratox assay. None of the 32 North American chocolate products, including 19 with precautionary labeling, contained detectable peanut protein. In contrast, 30.8% of products from western Europe without precautionary labeling contained detectable levels of peanut protein. Sixty-two percent of products from eastern Europe without precautionary labeling contained detectable peanut protein at levels of up to 245 ppm. The absence of precautionary labeling and the absence of the declaration of “peanut” as an ingredient in chocolate bars made in eastern and central Europe were not found to guarantee that these products were actually free of contaminating peanut protein. In contrast, North American manufacturers have attained a consistent level of safety and reliability for peanut-allergic consumers.

The history of European videogames has been so far overshadowed by the global impact of the Japanese and North American industries. However, European game development studios have played a major role in videogame history, and prominent videogames in popular culture, such as <i>Grand Theft Auto</i>, <i>Tomb Raider</i> and <i>Alone in the Dark</i> were made in Europe. This book proposes an exploration of European videogames, including both analyses of transnational aspects of European production and close readings of national specificities. It offers a kaleidoscope of European videogame culture, focusing on the analysis of European works and creators but also addressing contextual aspects and placing videogames within a wider sociocultural and philosophical ground. The aim of this collective work is to contribute to the creation of a, so far, almost non-existent yet necessary academic endeavour: a story of the works, authors, styles and cultures of the European videogame.

During the past seven years I have published several papers based upon preliminary investigations on the anatomy of the Holectypoida, an order of the Euechinoidea which, by general consent, is regarded as transitional between the Regular and Irregular sections of the class. Continued study, aided by increased mental and technical experience, has revealed an ever-increasing number of interesting features in the order, and has made possible more definite and confident surmises as to its affinities with other groups. The series of contributions here commenced is intended to amplify, and in some cases to correct, the statements made in my earlier papers. With very few exceptions the actual descriptions that are given in the former work still seem to be essentially correct, but every fresh examination, even of the same specimens, testifies to the incompleteness of most of the observations hitherto published. New material, better or differently preserved, often draws attention to features overlooked or discarded as unimportant in the examples already studied. No apology is needed for the publication of incomplete descriptions of natural objects, since complete knowledge is as yet nowhere attained. When inaccuracies of observation have been detected, their nature and cause will be stated frankly, accompanied, verbally or not, by suitable contrition.

Relative Motions

We use the baseline variation rates, which are obtained by the VLBI measuring in the past years (1979. /-1991.1), to estimate the relative motions among Eurasian, Pacific and North American plates. A comparion with the geological-based models has been made. In order to strengthen the VLBI constraints on the Euler vectors, we estimate the velocities of unstable stations in addition to the Euler vectors.

Recent reports from China, based mostly on the travels of North-American and European scholars, have broadened our knowledge of social conditions in that country. In most cases, the journeys of these scholarly visitors have been greatly facilitated by the availability of Chinese guides and interpreters who at times become their main source of contact with the people, especially in non-Mandarin speaking regions. Thus, great strides have been made in our understanding of the new society. But there is another source of traveller's reportage from China — the hundreds of ordinary overseas Chinese, especially those between the ages of 50 and 90, who every day visit their relatives on the mainland — and about whose personal observations and experiences we know very little. Consequently, there are gaps in our knowledge of every-day life in China, especially in the remote countryside of provinces such as Fukien, which are least frequented by delegations from Europe and America.
