Managing new PV plant connection to available grids to stay within standard limits with a case study

PV plants are increasing all over the world and they are becoming a distinct part of electric grids. Due to abundance of solar irradiation and almost constant amount of it in certain geographical latitudes, selection of proper capacity of PV plants depends mostly on available places for the site. in this paper, important measures for safe connection of a PV plant in terms of voltage requirements are addressed and several guidelines are introduced for this purpose. In addition, simulation results are included to prove some of the mentioned suggestions. a general algorithm is finally proposed to show the directions for safe connection of PV plants.

The mind games have already started: An in-depth examination of trash talking in Counter-Strike: Global Offensive esports using practice theory

Trash talking is a contentious and prevalent practice in traditional sports but few studies have examined its practice in esports – a computer-mediated form of sports competition in videogaming. This study used practice theory to identify different forms and dialectical relationships of trash talking in Counter-Strike: Global Offensive. Fifty hours of structured observations of professional tournaments were conducted followed by semi-structured interviews with fifteen spectators/casual gamers. Inductive analysis of data based on practice theory-related constructs identified varying perspectives on trash talk, and six distinct forms. Trash talk was directed towards players from opposing players, coaches, fans, casters and analysts. ‘Teabagging’ was the most controversial, but a predominantly positive ethos for trash talk was found, such that it was a distinct part of this esports scene. Theoretical and practice-oriented implications are discussed and a conceptualization of the practice of trash talk is given to encourage further debate and discussion in the field.

Redefinition of the cicada tribe Hemidictyini Distant, 1905, status of the tribe Iruanini Boulard, 1993 rev. stat., and the establishment of Hovanini n. tribe and Sapantangini n. tribe (Hemiptera: Cicadidae)

A recent paper by Ruschel & Campos (2019) on “leaf-winged” cicadas proposed a significant reorganization of the cicada tribe Hemidictyini Distant, 1905g, including synonymization of the monogeneric tribe Lacetasini Moulds & Marshall, 2018 following the results of a cladistic parsimony analysis of morphological characters. In this study, we reconsider and revise the morphological analysis of Ruschel & Campos and obtain new genetic data for Hemidictya. We find that their study suffers from a limited taxon sample, inappropriate outgroup selection, and misinterpretation of genitalic characters (uncus vs. claspers). We show that Hemidictyini sensu Ruschel & Campos includes members of multiple tribes and subfamilies, and we conclude that some of the taxonomic transfers by Ruschel & Campos are not supported. The two most similar and leaf-like cicadas, Hemidictya Burmeister, 1835 (South America) and Hovana Distant, 1905g (Madagascar), are probably not closely related but rather an excellent example of convergent evolution. Lacetasini is not a junior synonym of the Hemidictyini but a distinct part of the Tettigomyiinae Distant, 1905g as originally classified. We return or transfer the genera Lacetas Karsch, 1890, Iruana Distant, 1905g, Bafutalna Boulard, 1993, and Murphyalna Boulard, 2012 to the Lacetasini. With the transfer of all genera of Iruanina Boulard, 1993 and Bafutalnina Boulard, 1993 to Lacetasini and with Lacetas transferred to the Iruanina, Lacetasini n. syn. becomes a subjective junior synonym of Iruanini rev. stat. in the Tettigomyiinae. We assign Hovana to Hovanini n. tribe in the Tettigomyiinae and Sapantanga Distant, 1905g to Sapantangini n. tribe in the Tibicininae Distant, 1905b. We propose that Hemidictyini sensu novo contains only the genus Hemidictya and we assign the tribe to Tibicininae with a revised diagnosis.

Exploring the language layer of the dānastuti genre

The linguistic variedness of the ancient Vedic texts is a well-known fact. This can be observed within the Ṛgveda itself, the most ancient collection of hymns, and if one compares the language of the Ṛgveda with that of the Atharvaveda. Glimpses of Vedic dialects can be detected in several passages and words, although the poetic language displays a high degree of convention and normalisation. Among the hymns of the Rigveda few specific features can be attributed to the different families of bards, even though one can surmise that they belonged to different regions of the Vedic world. It is also likely that some families or so-called “branches” were linguistically mixed. The hymns resort to different genres of discourse. The dānastuti, lit. ‘praise of the gift’, marks a distinct part of the poetic competence. The passages in question, which are often limited to a single stanza, although others are more developed, making up a substantial part of the poem, are devoted to praise of the generosity of the patron, who is expected to reward the poet appropriately for his work. A comprehensive survey of these parts of the hymns of the Rigveda was made in the dissertation of Manilal Patel (1929), a student of Karl F. Geldner. This meritorious book describes mostly cultural, historical and ritual features. On the other hand, the familiar, and in cases crude or mischievous, tone of these pieces has been noted by several commentators of the Rigveda. It would be too simple, however, to consider that these parts faithfully reflect everyday speech. The paper aims to explore the linguistic traits of the dānastutis which contrast with the standard layer of the Ṛgvedic language at all levels: phonology, morphology, syntax, vocabulary. On the level of stylistics and poetics, it will be shown that the phraseology of the dānastutis relies on sophisticated devices derived from the standard phraseology which was used otherwise for the praise of the gods and goddesses in the core of the hymns.

Distribution and significance of foraminiferal biofacies on an aphotic Danian bryozoan mound, Karlstrup, Denmark

In this study, the distribution of benthic foraminifers across a Danian bryozoan mound in Karlstrup quarry, Denmark, is analysed in 22 samples using multivariate analysis. Three foraminiferal biofacies are established, each representing a distinct part of the mound. The Anomalinoides-Cibicides- Osangularia Biofacies is characteristic of the relatively pure carbonate sediments on the crest and flanks of the bryozoan mound. The Patellina Biofacies occurs at the mound flanks and is particularly common in marly sediments. The Spirillina Biofacies characterises the crest of the bryozoan mound in both marly and pure carbonate sediments. Variations in the plankton/benthos ratio indicate that the benthic foraminifers prefer the marly sediments to pure limestone and mound flanks relative to the mound top. It is likely that the benthic foraminifers avoided the more powerful currents at the mound crest. The common occurrence of spirillinids on the mound top may represent the remnant of a rich, siliceous sponge community.

Smoke, but No Fire? In Social Science, Focus on the Most Distinct Part

Causality in social science is hard to establish even through the finest comparative research. To ease the task of extracting causes from comparisons, we present the benefits of tracing particularities in any phenomenon under investigation. We introduce three real-world examples from 2011: British riots, worldwide anticapitalist protests, and the highway crash near Taunton in southwestern England. Whereas all of these three examples have broad causes, we embark on the quest after specific factors. The Taunton accident can send a powerful message to social scientists, which is about the danger of making general statements in their explanations. Instead of saying much but explaining little, the merit of singling out the specific is substantial. As social scientists, when we are faced with “smoke” but no “fire,” let us then focus on the part that is distinct.

The Distribution of Ascents of Size d or More in Partitions of n

A partition of a positive integer n is a finite sequence of positive integers a1, a2, . . ., ak such that a1+a2+ċ ċ ċ+ak=n and ai+1 ≥ ai for all i. Let d be a fixed positive integer. We say that we have an ascent of size d or more if ai+1 ≥ ai+d.We determine the mean, the variance and the limiting distribution of the number of ascents of size d or more (equivalently, the number of distinct part sizes of multiplicity d or more) in the partitions of n.
