Abstract:
During the spring and summer of 2003, symptoms of mosaic, mottle, and crinkle were observed in cauliflower (Brassica oleracea) and turnip (Brassica rapa) fields in the Qazvin and Esfahan provinces of Iran, respectively. Leaf extracts of these plants, made infective by mechanical inoculation, caused necrotic local lesions on Chenopodium amaranticolor, chlorotic ring spot on Nicotiana tabacum cv. Samsun, and chlorotic local lesions followed by systemic mosaic on Brassica rapa (1). Using double-antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA) and specific polyclonal antibodies (As-0120 and PV-0355) that were kindly prepared by S. Winter (DSMZ, Braunschweig, Germany), the samples were tested for the presence of Radish mosaic virus (RaMV) (family Comoviridae, genus Comovirus). ELISA results showed that the original leaf samples and inoculated indicator plants reacted positively to RaMV antibodies. RaMV has been reported in the United States, Japan, and Europe on turnip and other crucifers (1,2). To our knowledge, this is the first report of RaMV occurring in Iran. References: (1) R. N.

Abstract:
AbstractIn recent years, the modernisation process has led to a radical transformation of the territory, producing waste in various forms (José Zapata Campos and Michael Hall in Organising waste in the city, Bristol University Press, 2013). Waste, not only in the sense of domestic or industrial waste but also in a broader concept linked to the territory and landscape’s spatial context. The concept relates to the degraded and subsequently abandoned area. Places understood as waste, areas expelled from the city and extraneous as they have no use and are now at the end of their life cycle.These areas, recognised as wastescapes (Amenta and Attademo in CRIOS 12:79–88, 2016) or a waste of land (Berger in Drosscape: Wasting land in urban America, Princeton Architectural Press, 2007), draw the and landscape’s mosaic increasingly fragmented. Also, current mobility requirements lead to a discussion on the design of road infrastructure. While in some cases the tendency is to upgrade existing ones, in others the choice is to design and build new routes. These new routes are causing many problems for the landscape, which is becoming even more devastated. A territory made up of linear elements, and ecosystem networks that physically connect urban space to environmental space create multiple landscapes within which transport networks act as a glue between the different urban poles and as a generator of abandoned areas (Russo in Techne 15:39–44, 2018).With this in mind, the study aims to analyse and assess, through spatial indicators, the potential that abandoned sites close to major road infrastructures can offer to society not only in economic but also in environmental terms.Starting from the Focus Area’s municipalities identified in the Horizon 2020 REPAiR project (Geldermans et al., in REPAiR project: REsource Management in Peri-urban AReas: Going beyond urban metabolism, 2017) for the Neapolitan context, only four of the eleven municipalities identified by the project are considered to make the analyses exhaustive and replicable in other contexts.The methodology defined the relationships between the built environment and abandoned infrastructure spaces, which cross and fragment the city and are devoid of functionality.The study had structured in three main phases: Identification of the abandoned interstitial areas of the road and neighbouring infrastructures in the municipalities of Afragola, Cardito, Casalnuovo di Napoli and Casoria (municipal territories of the metropolitan city of Naples); Analysis of the indexes of proximity to the urbanised areas and connectivity between the abandoned interstitial areas and the urbanised fabric; Evaluate these indices for the suburban areas to identify the attractiveness for future urban regeneration processes. In this sense, the attractiveness potential of abandoned interstitial spaces of road infrastructures had assessed.If included in a decision support system, these analyses and evaluations would support the definition of urban regeneration actions. In this sense, it evaluated the potential for the attractiveness of abandoned interstitial areas of road infrastructure. In this context, particular attention is paid to the environment in which we live and its protection and preservation.

Abstract:
Abstract Atlantic’s simultaneous release of James Carter’s Chasin’ the Gypsy, a tribute to Django Reinhardt, and Layin’ in the Cut, an exercise in jazz funk, reminds me of a moment from my childhood when the same label released two LPs by Bobby Darin, At the Copa and For Teenagers Only. Darin was trying to cross over to a grown-up, moneyed audience while keeping the allowanced one in line. Carter, as he notes in a press release, wants, “in light of the millennium thing, to have one foot in the past, in a musical sense, and another moving forward in time.” So which is which? The way I hear it, the noisily diverting Layin’ in the Cut takes the limited idea of virtuoso noodling over an electric backbeat as far as it can go, while the creamy homage opens new vistas in the realm of reinterpretation. Admittedly, this realm is no longer a princely one. The jazz landscape is littered with pointless tributes and reinterpretations. What a relief to hack through all the Monk and Ellington salutes to get back to Monk and Ellington. Still, I don’t think Chasin’ the Gypsy will fade so quickly. It will make you want to hear the great Django—the better you know the originals, the more you can savor Carter’s heady adaptations. But loving the Romany legend, many of whose best sides have now been issued by Mosaic as The Complete Django Reinhardt and Quintet of the Hot Club of France Swing/HMV Sessions 1936–1948, will not satisfy the anticipation Carter creates for his own faithfully intense, high-calorie vision. Carter’s approach to the past, demonstrated less pointedly on earlier records, is not to turn backward on bended knee, but to go after it like a benevolent Ahab. He makes Django a 21st-century man.

Abstract:
In an epoch defined by China's staggering economic ascent, the global panorama witnesses an expansive sprawl of Beijing's interests, notably in regions as diverse as the Middle East and North Africa. Central to this burgeoning influence is China's deft and strategic employment of “soft power” strategies, fostering calculated and symbiotic “strategic partnerships” with Arab states. This diplomatic approach, characterized by nuanced elements such as non-interventionism, cultural dissemination, and collaborative economic ventures, stands as a linchpin in China's diplomatic toolkit. In the face of Western portrayals casting shadows of a “Chinese menace,” Beijing finds itself compelled to vehemently defend its peaceful policy objectives. Beyond mere economic gains, China's motives are laced with geopolitical and geostrategic considerations, adding layers of depth to its engagements. This meticulously orchestrated outreach encapsulates a significant facet of China's broader recalibration towards the Western sphere. This chapter undertakes a comprehensive exploration of the intricate and manifold facets of China's soft power diplomacy, offering a panoramic view of its profound influence extending across the intricate landscapes of Asia and the Middle East. Through a nuanced lens, it illuminates the mosaic of strategies, motivations, and implications that underpin China's burgeoning presence in these pivotal regions, painting a vivid tapestry of its ever-evolving global entrenchment. Various sources are used as support for the chapter. Press conferences, readings, academic journals, and scholarly articles are just some of the references found in the chapter. Additionally, expert opinions from well-renowned scholars were taken into consideration about China's growing influence in Asia and the Middle East in the fields of trade, technology, and politics. Furthermore, visual representations, such as images and graphs, are placed to facilitate selected aspects for the readers.

Abstract:
Abstract This chapter discusses the illustration of Yeats’s poetry and prose across his writing life as he moved publishers from Charles Kegan Paul to T. Fisher Unwin, to the Cuala Press, and to Macmillan. Yeats revised and refined his aesthetic preferences from photomechanically reproduced narrative paintings to Celtic interlace designs, symbolist flora and fauna to line work inspired by Byzantine mosaics, and abstract, geometrical renderings that aligned with his mythography of gyres and historical cycles. The chapter begins with Yeats’s earliest illustrated poems for magazines decorated by his brother, Jack Yeats, before turning to the poet’s more sustained collaboration with Althea Gyles for Unwin book covers at the turn of century, including The Secret Rose. The third section discusses the minimalist decorative aesthetic of Dun Emer and the Cuala Press, and the extent to which Yeats favoured a more restrained and uniform design identity to his books in later years. The fourth section traces Yeats’s correspondence and collaboration with Norah McGuinness and T. Sturge Moore on some of his most iconic book covers for Macmillan. His growing interest in geometry and the aesthetics of Byzantine mosaics in the 1920s inform several of these covers, including The Tower, The Winding Stair, and the Stories of Red Hanrahan and the Secret Rose. With the selection of new artists and livery to cover old books, illustration afforded Yeats an opportunity to step backwards in history to an abstract or symbolic phase of art that was antiquated and yet strikingly modern and refreshing.

Abstract:
Among the books owned by Edward Pococke (1604–1691), Regius Professor of Hebrew and Laudian Professor of Arabic at Oxford, were numerous copies of the Mishnah with Maimonides’ Commentary, including a manuscript now known to have been annotated by Maimonides himself (Bodleian Library, MS Poc. 295). This chapter considers how Pococke studied these texts and whether he realized that he owned part of Maimonides’ working copy. An analysis of Pococke’s annotated books and published works shows that he acquired texts from Aleppo, studied the Mishnah under Rabbi Jacob Roman of Constantinople, used his copies of Maimonides’ Commentary to edit excerpts for publication (Porta Mosis, 1655), and deposited manuscripts at the press to serve as printers’ copy. Pococke’s incomplete knowledge of the transmission of Maimonides’ works and the caution with which he treated the autograph emendations in MS Poc. 295 suggest that the provenance of this manuscript was unknown.

Full text
Abstract:
The human retina discretely samples the visual scene with spatial arrays of sampling elements such as photoreceptors and ganglion cell receptive fields. These sampling operations potentially render the human visual system susceptible to aliasing; if the retinal image changes too rapidly over distances comparable to the spacing between sample points, the visual system can make errors in reconstructing the visual scene. Aliasing can be seen when interference fringes of sufficiently high spatial frequency are imaged on the cone mosaic (reviewed in Williams, in press). Subtle aliasing effects can also be seen when viewing conventional high contrast, high spatial frequency gratings in the periphery (e.g. Smith and Cass, 1987; Thibos, Walsh, and Cheney, 1987; Galvin and Williams, submitted). However, aliasing is remarkably difficult to observe under most normal viewing conditions. Many mechanisms have been suggested as offering the visual system protection against aliasing at various locations across the visual field. This talk will assemble the available evidence in order to weigh the the effectiveness of these proposed mechanisms.

Grumet, Rebecca, and Benjamin Raccah. Identification of Potyviral Domains Controlling Systemic Infection, Host Range and Aphid Transmission. United States Department of Agriculture, July 2000. http://dx.doi.org/10.32747/2000.7695842.bard.

Full text
Abstract:
Potyviruses form one of the largest and most economically important groups of plant viruses. Individual potyviruses and their isolates vary in symptom expression, host range, and ability to overcome host resistance genes. Understanding factors influencing these biological characteristics is of agricultural importance for epidemiology and deployment of resistance strategies. Cucurbit crops are subject to severe losses by several potyviruses including the highly aggressive and variable zucchini yellow mosaic virus (ZYMV). In this project we sought to investigate protein domains in ZYMV that influence systemic infection and host range. Particular emphasis was on coat protein (CP), because of known functions in both cell to cell and long distance movement, and helper component-protease (HC-Pro), which has been implicated to play a role in symptom development and long distance movement. These two genes are also essential for aphid mediated transmission, and domains that influence disease development may also influence transmissibility. The objectives of the approved BARD project were to test roles of specific domains in the CP and HC-Pro by making sequence alterations or switches between different isolates and viruses, and testing for infectivity, host range, and aphid transmissibility. These objectives were largely achieved as described below. Finally, we also initiated new research to identify host factors interacting with potyviral proteins and demonstrated interaction between the ZYMV RNA dependent RNA polymerase and host poly-(A)-binding protein (Wang et al., in press). The focus of the CP studies (MSU) was to investigate the role of the highly variable amino terminus (NT) in host range determination and systemic infection. Hybrid ZYMV infectious clones were produced by substituting the CP-NT of ZYMV with either the CP-NT from watermelon mosaic virus (overlapping, but broader host range) or tobacco etch virus (TEV) (non- overlapping host range) (Grumet et al., 2000; Ullah ct al., in prep). Although both hybrid viruses initially established systemic infection, indicating that even the non-cucurbit adapted TEV CP-NT could facilitate long distance transport in cucurbits, after approximately 4-6, the plants inoculated with the TEV-CPNT hybrid exhibited a distinct recovery of reduced symptoms, virus titer, and virus specific protection against secondary infection. These results suggest that the plant recognizes the presence of the TEV CP-NT, which has not been adapted to infection of cucurbits, and initiates defense responses. The CP-NT also appears to play a role in naturally occurring resistance conferred by the zym locus in the cucumber line 'Dina-1'. Patterns of virus accumulation indicated that expression of resistance is developmentally controlled and is due to a block in virus movement. Switches between the core and NT domains of ZYMV-NAA (does not cause veinal chlorosis on 'Dina-1'), and ZYMV-Ct (causes veinal chlorosis), indicated that the resistance response likely involves interaction with the CP-NT (Ullah and Grumet, submitted). At the Volcani Center the main thrust was to identify domains in the HC-Pro that affect symptom expression or aphid transmissibility. From the data reported in the first and second year report and in the attached publications (Peng et al. 1998; Kadouri et al. 1998; Raccah et al. 2000: it was shown that: 1. The mutation from PTK to PAK resulted in milder symptoms of the virus on squash, 2. Two mutations, PAK and ATK, resulted in total loss of helper activity, 3. It was established for the first time that the PTK domain is involved in binding of the HC-Pro to the potyvirus particle, and 4. Some of these experiments required greater amount of HC-Pro, therefore a simpler and more efficient purification method was developed based on Ni2+ resin.
