The object of this paper was to show the true character of storms, illustrated by those of 2d, 3d, and 4th December 1863. It was pointed out that the mode usually adopted of laying down the isobarometric lines was calculated to present an erroneous view of their figure or form. The laying down representative lines in round numbers of 5 millemetres in each, or in two-tenths of an inch of barometric readings, lead deceptively to the conclusion that the areas of least pressure were circular or elliptical.It was then shown that the lines of equal pressures were ribbed into the latitudinal line of minimum barometer, which was usually found running north and south, sometimes nearly straight, but often curved, with its convex side towards the east. The minimum line of barometer was easily fixed by consulting the self-registering barometers. The minimum line of barometer was shown to have been on the meridian of London at 8 a.m. of the 3d December, and apparently nearly straight from Algiers to the Orkney Islands.

Too many of Africa’s nation-states, both north and south of the Sahara, remain convulsed by combatants, infiltrated by insurgents, and damaged deeply either by the self-inflicted wounds of civil conflict or attacked from within by Islamists supported from without and loyal to externally propagated ideologies. In their founding years, independent northern and southern Africa harbored conflicts that tore new nations apart. In contemporary times some of those civil wars linger, joined as they have been since the dawning of the new century by newly spawned fundamentalist revolutionaries and by reactionaries who regard constituted authority and modern political instrumentalities as illegitimate, even haram—“forbidden.” Although there are fewer civil conflict deaths per year than there were in the 1980s and 1990s, there are many more episodes of terror, and fatalities, than there were in those times. And the seemingly intractable nature of some of the conflicts and many of the campaigns against terror give the impression that sections of Africa—Egypt and the Sinai; Algeria, Libya, and the Sahel; the Horn of Africa and Kenya; Nigeria and its northeastern neighbors; and the Democratic Republic of Congo—are today immured in warfare that will not easily end.

The division of Sudan into two countries on 9 July 2011 following the self-determination referendum of 9 January represents a rare development in Africa. Few examples exist of new state formations in the continent after the end of the colonial period. Answering the call of the IJMES editor to reflect on what this event will mean for our understanding of Sudan might take us in several directions. Let me use this opportunity to comment on two themes that have concerned me lately: the role of the state and the possibility that multiple national identities will evolve in North and South Sudan.

Islanders tend to develop rules and methods for regulating the use of the marine environment and its accessible resources. Where islands have been subject to the influence or domination of external political forces, and such resources have become the subject of increased demand, then differences of approach, of understanding and of patterns of use can come into conflict. This is especially so where there is increased emphasis on coastal development, pressures to privatize and register coastal land and to regulate the commercial exploitation of marine resources. This article considers the Shetland & Orkney Islands from the north and Fiji, Vanuatu and the Solomon Islands from the south, drawing out similarities and differences of legal approaches to key issues relevant to the foreshore and the coastal zone.

How do stereotypes – as rhetorical, homogenising claims about the Self and Other – survive despite their users having personal experiences that contradict them? This article addresses this question by examining why the Christian and Muslim inhabitants of the Spanish enclave of Ceuta insist the ‘moro’ is a cunning, hostile antagonist, even when their interactions with Moroccans tend to be profitable, and even as ethnographers of mainland Spain report widespread revisions of the Moorish migrant’s negative image and the country’s Islamic past. Building on the interpretative model of stereotypes developed by Herzfeld, Brown and Theodossopolous, I argue that the ‘moro’ persists as an unequivocally malevolent character because it (1) is cultivated by a number of financially interested actors and (2) is central to the discursive strategies Ceutans use to respond to the political threats to their españolidad from both north and south.

The essence of Eurasia is being in between East and West, North and South Georgia as a Eurasian country undeniably belongs neither to West nor to East and does not bridge them being geographically flanked by these continents. The self-contained miniature world of part-singing in Georgia is considered as a model for the study of Eurasian polyphony, i.e., an ethnogeomusical unity whose characteristics supposedly occur in different ethnogeographical areas. The author avoids the paradigm of origin and concentrates on an examination of spatial patterns in the distribution of part-singing that constitutes the most puzzling scholarly question.

The current article investigates the relation between values and modernization applying some elements of the method proposed by Inglehart and Welzel (the authors of the Human Development Sequence Theory) to the data of Shalom Schwartz. The values survey by Schwartz specifies two main value axes, namely, conservation versus openness to change and self-transcendence versus self-enhancement. Our research has revealed that the correlation between these two value axes differs in its direction when estimated for “macro-Europe” (that includes Europe and former settlement colonies of North and South America and Oceania) and “Afroasia” (that includes Asia and Africa). In “macro-Europe,” we deal with a significant positive correlation between openness to change and self-transcendence, whereas in “Afroasia,” this correlation is strong, significant, and negative. We investigate the possible impact of modernization on this difference. To do this, we approximate modernization through such indicators as gross domestic product (GDP) per capita and the proportions of the labor force employed in various sectors of economy. We find that, in both megazones, modernization is accompanied by increasing openness to change values. As for the self-transcendence/self-enhancement axis, we propose two possible explanations of the different dynamics observed in Europe and in “the East” (Asia and North Africa), namely, (a) that Eastern and Western societies find themselves at different modernization stages and (b) that this difference is accounted for by different civilizational patterns. Further analysis suggests that the latter explanation might be more plausible.

Chthamalus stellatus is a littoral barnacle very similar in habitat and general ecological relations to another littoral barnacle, Balanus balanoides. In those localities where both species flourish they compete considerably for space, and also possibly for food. The fact that B. balanoides settles sooner after the winter storms than does Chthamalus probably favours the former.Chthamalus is characteristically a southern species and Balanus balanoides a northern one, but the north and south ranges of the two species overlap in the British Isles and in France. The determining factor is presumably temperature.Chthamalus is an Atlantic species, and Balanus balanoides is more characteristically a North Sea species. The essential factor in Atlantic water remains unknown, although in respect of a need for Atlantic water Chthamalus resembles Sagitta elegans and intertidal Echinus esculent.

AbstractAutism spectrum disorder (ASD) subjects can present temporary behaviors of acute agitation and aggressiveness, named problem behaviors. They have been shown to be consistent with the self-organized criticality (SOC), a model wherein occasionally occurring “catastrophic events” are necessary in order to maintain a self-organized “critical equilibrium.” The SOC can represent the psychopathology network structures and additionally suggests that they can be considered as self-organized systems.

The major protein of the blue-green algae is the biliprotein, C-phycocyanin (Amax = 620 nm), which is presumed to exist in the cell in the form of distinct aggregates called phycobilisomes. The self-assembly of C-phycocyanin from monomer to hexamer has been extensively studied, but the proposed next step in the assembly of a phycobilisome, the formation of 19s subunits, is completely unknown. We have used electron microscopy and analytical ultracentrifugation in combination with a method for rapid and gentle extraction of phycocyanin to study its subunit structure and assembly.To establish the existence of phycobilisomes, cells of P. boryanum in the log phase of growth, growing at a light intensity of 200 foot candles, were fixed in 2% glutaraldehyde in 0.1M cacodylate buffer, pH 7.0, for 3 hours at 4°C. The cells were post-fixed in 1% OsO4 in the same buffer overnight. Material was stained for 1 hour in uranyl acetate (1%), dehydrated and embedded in araldite and examined in thin sections.

A mutant of Bacillus licheniformis 749/C, NM 105 exhibits some notable properties, e.g., arrest of alkaline phosphatase secretion and overexpression and hypersecretion of RS protein. Although RS is known to be widely distributed in many microbes, it is rarely found, with a few exceptions, in laboratory cultures of microorganisms. RS protein is a structural protein and has the unusual properties to form aggregate. This characteristic may have been responsible for the self assembly of RS into regular tetragonal structures. Another uncommon characteristic of RS is that enhanced synthesis and secretion which occurs when the cells cease to grow. Assembled RS protein with a tetragonal structure is not seen inside cells at any stage of cell growth including cells in the stationary phase of growth. Gel electrophoresis of the culture supernatant shows a very large amount of RS protein in the stationary culture of the B. licheniformis. It seems, Therefore, that the RS protein is cotranslationally secreted and self assembled on the envelope surface.
