Earlier research on feather morphology emphasized comprehensively on the body contour feather than various other types of feathers. Therefore, we conducted a systematic study on all feather types of the Indian Pitta Pitta brachyura, a passerine bird native to the Indian subcontinent. Feather barbs from wing contour, tail contour, body contour, semiplume, down, powder down, and bristle feathers were retrieved from the bird and observed under a light microscope. Primary flight feathers from the right and left wing were longest (85.17 mm and 87.32 mm, respectively), whereas bristle feathers were the shortest (5.31 mm). The mean barb length was observed to be the highest (11.37±0.47 mm) in the wing feather followed by body contour (8.31±0.39 mm), semiplume (8.27±0.22 mm), tail feather (7.85±0.50 mm), down (6.45±0.21 mm), powder down (6.04±0.23 mm), and bristle (2.70±0.07 mm).  Pearson correlation was found positive for barb length and feather length of down feathers (r= 0.996, p ≤0.05). We observed a novel type of barb the first time from dorsal body contour feather having plumulaceous barbules at the base followed by pennaceous barbules. This unique barbule arrangement is termed ‘sub-plumulaceous’ as it is distinct and analogous to known ‘sub-pennaceous’ type arrangement found absent in passerines.

The 1992 Salvadoran peace accords ended a 12-year civil war and forced modest democratic reforms on a state long dominated by a ruthless oligarchy and military. However, the new system represented a shallow version of democracy that remained largely unresponsive to the population. For two decades the far-right Alianza Republicana Nacionalista (Nationalist Republican Alliance [ARENA]) party held the presidency and used it to enact pro-business economic policies of austerity, privatization, and deregulation. In 2009, the left-wing opposition party, the Farabundo Martí National Liberation Front (FMLN), won the presidential elections for the first time. Yet despite winning some notable progressive reforms, the FMLN did not seek, much less achieve, a radical break from the neoliberal policies of previous administrations. FMLN leaders opted to continue a number of pro-capitalist policies while pursuing reforms to ameliorate the worst symptoms of the system, not overthrow it. The FMLN’s shift away from revolutionary socialism is attributable to several factors: a political and media terrain that still heavily favors the right, the continued influence of the United States government, and private investors’ control over the economy. These constraints were vitally important during the tenures of FMLN presidents Mauricio Funes (2009–2014) and Salvador Sánchez Cerén (2014–2019). El Salvador’s political trajectory since 1992, and especially during the FMLN’s decade in the presidency, offers insights into the constraints facing various left-of-center governments elected across Latin America in the early 21st century.

Abstract: Estimated height has an important role in identifying unknown bodies, incomplete, and the residual bone. Measurements in the long bones such as the forearm are better used to determine the height because it is the best result among the other members of the body size. The purpose of this study was to analyzed a correlation between the forearm length with the height of Banjar Tribe’s students of Medical Faculty of Lambung Mangkurat University and to obtain height estimation formula based on the forearm length in Banjar Tribe’ female. The research method is an analytical observation with cross sectional approach. The research subjects were taken by purposive sampling with samples of 52 people and were analyzed by Pearson correlation and linear regression analysis. The results of Pearson test showed that the value of p = 0,00 for the right and left arm with the value of r = 0.974 for the right arm and r = 0.972 for the left arm, which means there is a very strong relationship between the forearm length with height. It is concluded that there is a very strong correlation between the forearm length with students height of Banjar tribe Medical Faculty of Lambung Mangkurat University with height estimation formula Height = 63,838 + 3,693 x length of the right forearm and Height = 61,873 + 3,780 x left forearm length. Keywords: identification, height estimation, Banjar tribe’ female Abstrak: Memperkirakan tinggi badan mempunyai peranan penting dalam mengidentifikasi jenazah tidak dikenal, tidak lengkap, dan sisa tulang.

Using Schwarz's integral formula, new series expressions are obtained for the low-and high-frequency limiting values of the added-mass tensor of partially submerged cylinders of arbitrary shape, including nonsmooth and non-symmetric ones. These series contain the Fourier coefficients of simple geometric quantities of the body contour, and their rate of convergence is controlled by geometrical parameters reflecting the smoothness of the double-body contour. Alternative expressions of a more usual form, in terms of the conformal mapping coefficients of the body contour, are also presented. The off-diagonal elements of the limiting added-mass tensors as well as the low-frequency added moment of inertia for nonsymmetric sections are apparently given for the first time. As an application, closed-form expressions for the limiting added-mass coefficients of an extended-Lewis family of ship sections are obtained. Numerical results are also presented for an extended-Lewis, a rectangular, and three ogival sections. The convergence of the frequency-dependent elements of the added-mass tensors towards their limiting values is also discussed in detail, and it is numerically illustrated for a heeled ship-like section.

Marine representatives of the phylum Gastrotricha are reported for the first time from the State of New Jersey, USA. Littoral and shallow sublittoral sediment collected at Ship Bottom on Long Beach Island, near Atlantic City, yielded 11 species belonging to eight genera in six families in the orders Macrodasyida (four genera in three families) and Chaetonotida (four genera in three families). Littoral samples were richer than the one sublittoral sample (7 vs 4 spp.). Among the taxa was a large, undescribed species of Tetranchyroderma characterized by the following key traits: total body length up to 605 μm; cuticular covering complete, made up of pentancres; a pair of cephalic tentacles; dorsal adhesive tubes arranged in dorsal and dorsolateral columns; a pair of ventral adhesive tubes arising from a common base, near the perigenital area only on the right side; peculiar cuticular openings ‘stomata’ along the ventrolateral margins of the body; protogynous hermaphroditism. Tetranchyroderma weissi sp. nov. is, at least in the investigated location, restricted to the sediment layers below 20 cm of the intertidal zone, and is able to live in thiobiotic sediment. A key to the described species of the world based on easily discernible traits, visible in both living and formalin-fixed specimens is provided.

Social and economic inequalities between the city centre and peripheral belts persist for many years in Rome districts, in parallel to the on-going suburban sprawl. That yields political effects too, since electoral results from 2000 to 2018 highlight sharp political polarization: votes for left-wing (right-wing or Five Star Movement) candidates are inversely (directly) proportional to distance from Capitoline Hill. Notably, in 2018 general election, the left-wing coalition prevailed in central districts only, where education levels and personal income are very high, and (even if only slightly) in historical periphery, where it keeps consensus on progressive, inclusive and liberal policies. The opposite holds for the new populist Five Star Movement, that prevailed in low-density periphery inside the Orbital, in far-off sprawled districts and in Ostia coastal area. However, the right-wing coalition won in Rome as a whole, by more homogeneous and even inter-classist consensus, and prevailed outside the Orbital thanks to the League, that had for the very first time many votes in the Roman peripheries. As a matter of facts, both right-wing and populist policies seem easier to the extent that suburban citizens feel deprived since harmed by economic crisis, unsafe and worried about immigrants, far from elected bodies, scarcely endowed with public services.

Motor asymmetries are wide spread among vertebrate and invertebrate animals. More frequently asymmetries in the use of paired appendages and turns of the body in space become the subject of research. Unpaired organs, positioned along the long axis of the body become the subjects of investigation of the functional asymmetries less often. Here we performed a preliminary estimation of populational characteristics of asymmetry in the turn of the head while resting in Mallards (Anas platyrynchos) from two distinct wintering groups. On tracks along the banks of rivers and channels in the center of Saint-Petersburg, Russia, and along the Buksnesfjord at the Vestvagøy island (Lofoten Islands, Norway Sea, Norway), we recorded the position of the head (under the left wing, or under the right wing) in resting birds ones for each individual. Totally we recorded head position in 151 individuals from Saint-Petersburg and in 77 individuals at Vestvagøy. Individuals keeping heads under the right wing were predominant in Saint-Petersburg, while at Vestvagøy the proportion of «left» and «right» individuals did not differ significantly from 1:1. Difference between the populations was significant, while sex differences in both populations were not found. We discuss possible reasons for the differences in population characteristics of asymmetry in the head position («head-under-wing»), particularly conditions of wintering, birds behaviour. We conclude that the study of different wintering groups of mallards can be possibly perspective for estimation of population status by assessment of relative proportion of «left» and «right» birds.

The Butterfly Flower Shower (BFS) Human Behaviour Model describes human behaviour in each demanding, possible accidental situation. The BFS human behaviour model is presented for a traffic situation. The key elements (perception, cognition, reaction) of the human behaviour are identified. Also possible limitations and errors in all elements of human behaviour are presented. The model is presented as the butterfly on the flower under the shower of interventions. The flower is environment describing traffic infrastructure composed of the environment, technology and organization. The body of the butterfly is human cognition with personality and motivation. The left wing of the butterfly is the driver’s perception. The right wing of the butterfly is the driver’s reaction. The butterfly presents the driver, the flower presents the road – the traffic infrastructure and the shower presents the shower of humanization interventions into the traffic infrastructure and into the driver. The drops from the shower are related to identified limitations in the traffic infrastructure and to the driver. They are focused on the improvements of perception, cognition and reaction abilities of the driver also with investments into the traffic infrastructure.

The post-Brexit, post-Trump climate in the EU has seen a series of challenges from the right wing of politics to the liberal consensus of recent years (e.g. the rise of Gert Wilders in the Netherlands and the increased support for Alternativ für Deutschland in the 2017 German election). This article examines the gendering and embodiment of the new far right in France and the UK. It offers a comparative focus on two recent political challengers from the right who are female: Marine Le Pen (born 1968), the leader of the Front national in France since 2011, and Anne Marie Waters (born 1977), the Islam-critical candidate who was runner-up for the UK Independence Party (UKIP) leadership in the UK in 2017, and who has since started her own political party, For Britain. The article focuses on media coverage of, and self-representation by, these two figures. It argues that the discourse of the ‘right’ and ‘left’ wings has, historically, been gendered on the basis of assumptions that women are naturally more inclined towards consensus-building, collectivity and compassion (and therefore left-wing politics), by dint of their biological function as child-bearers and traditional gender role as care-givers. Right-leaning women have been treated as anomalies, by both feminist political analysts and the mainstream media. Feminist concerns over the very existence of right-wing women is suggested by books such as second-wave feminist Andrea Dworkin’s Right-Wing Women (1983), the more recent edited collection by Paola Bacchetta and Margaret Power, also called Right-Wing Women (2013) and, in the French context, Claudie Lesselier and Fiametta Venner’s L’Extrême Droite et les femmes (1997). Le Pen and Waters appear as doubly aberrant, doubly exceptional figures – firstly as (far-)right-wing women and secondly as (far-)right-wing female leaders. The article considers the stakes of our categorical understandings of (gendered and political) identity more broadly. Specifically, by introducing the original critical concept of ‘identity category violation’, it analyses the ways in which the recent trend for identity politics on the left in the West, often under the banner of ‘intersectionality’, leads to over-simplified understandings of how categories of gendered, sexual, class and race-based identities are assumed to determine political affiliation.
