    Nature-based solutions (NBSs) are measures reflecting the ‘cooperation with nature’ approach: mitigating fluvial flood risk while being cost-effective, resource-efficient, and providing numerous environmental, social, and economic benefits. Since 2015, the United Nations (UN) 2030 Agenda has provided UN member states with goals, targets, and indicators to facilitate an integrated approach focusing on economic, environmental, and social improvements simultaneously. The aim of this study is to evaluate the contribution of fluvial NBSs to the UN 2030 Agenda, using all its components: Sustainable Development Goals (SDGs), targets, and indicators. We propose a four-step framework with inputs from the UN 2030 Agenda, scientific literature, and case studies. The framework provides a set of fluvial flooding indicators that are linked to SDG indicators of the UN 2030 Agenda. Finally, the fluvial flooding indicators are tested by applying them to a case study, the Eddleston Water Project, aiming to examine its contribution to the UN 2030 Agenda. This reveals that the Eddleston Water Project contributes to 9 SDGs and 33 SDG targets from environmental, economic, societal, policy, and technical perspectives. Our framework aims to enhance the systematic considerations of the SDG indicators, adjust their notion to the system of interest, and thereby enhance the link between the sustainability performance of NBSs and the UN 2030 AgendaRivers, Ports, Waterways and Dredging Engineerin

    An Interesting Charmonium State Formation and Decay : ppˉ1D21P1γp \bar p \to ^1D_2 \to ^1P_1 \gamma

    Massless perturbative QCD forbids, at leading order, the exclusive annihilation of proton-antiproton into some charmonium states, which, however, have been observed in the ppˉp\bar p channel, indicating the significance of higher order and non perturbative effects in the few GeV energy region. The most well known cases are those of the 1S0^1S_0 (ηc\eta_c) and the 1P1^1P_1. The case of the 1D2^1D_2 is considered here and a way of detecting such a state through its typical angular distribution in the radiative decay 1D2^1D_2 \to 1P1γ^1P_1 \gamma is suggested. Estimates of the branching ratio BR(1D2ppˉ)BR(^1D_2 \to p\bar p), as given by a quark-diquark model of the nucleon, mass corrections and an instanton induced process are presented.Comment: 9 pages (no figures), Plain TeX, CBPF-NF-014/94, INFNCA-TH-94-

    <p>Abstract</p> <p>Background</p> <p>The structure of health care in Greece is receiving increased attention to improve its cost-effectiveness. We sought to examine the epidemiological characteristics of patients presenting to the vascular emergency department of a Greek tertiary care hospital during a 2-year period. We studied all patients presenting to the emergency department of vascular surgery at Red Cross Hospital, Athens, Greece between 1<sup>st </sup>January 2009 and 31st December 2010.</p> <p>Results</p> <p>Overall, 2452 (49.4%) out of 4961 patients suffered from pathologies that should have been treated in primary health care. Only 2509 (50.6%) needed vascular surgical intervention.</p> <p>Conclusions</p> <p>The emergency department of vascular surgery in a Greek tertiary care hospital has to treat a remarkably high percentage of patients suitable for the primary health care level. These results suggest that an improvement in the structure of health care is needed in Greece.</p

    On the Nucleon Distribution Amplitude: The Heterotic Solution

    Full text link
    We present a new nucleon distribution amplitude which amalgamates features of the Chernyak-Ogloblin-Zhitnitsky model with those of the Gari-Stefanis model. This "heterotic" solution provides the possibility to have asymptotically a small ratio \hbox{GMn/GMp0.1\vert G_{M}^{n}\vert/G_{M}^{p}\le 0.1}, while fulfilling most of the sum-rule requirements up to the third order. Using this nucleon distribution amplitude we calculate the electromagnetic and weak nucleon form factors, the transition form factor γpΔ+\gamma p \Delta^{+} and the decay widths of the charmonium levels 3S1^3S_{1}, 3P1^3P_{1}, and 3P2^3P_{2} into ppˉp\bar p. The agreement with the available data is remarkable in all cases.Comment: 15 pages, RUB-TPII-21/92 Preprin

    Clientelistic networks and local corruption: Evidence from Western Crete DIMITRIOS CHRISTOPOULOS

    Get PDF
    In this article, the attitudes and interaction of local political and business elites in western Crete are examined by means of an attitudinal survey, triangulated with data from in-depth interviews, conducted between July and October 1991. The data examined indicate that the endemic prevalence of clientelistic networks creates the background for corruption, although evidence of corrupt practice is not strong. In this analysis it is presumed that the attitudes and perceptions of key actors are affected by a definition of corruption that is relevant to their particular civil society alone. Data analyzed here suggest that local élite attitudes towards corruption are not perceived to affect the standards of conduct at the local level. It can also be deduced that if corruption is linked to the problems of administrative efficiency and economic development of the region, these can be related to vertical clientelistic networks with the national centre

    Extranodal NK/T Cell Lymphoma, Nasal Type with Palatal Involvement: A Rare Case Report and Literature Review

    No full text
    T-cell lymphomas are infrequently encountered in the head and neck area, with the most common subtype being Extranodal NK/T cell lymphoma, nasal type (ENKTL-NT). ENKTL-NT shows a predilection for midline facial structures presenting with ulcerative destructive lesions, whereas palatal involvement is one of the most prominent signs from the oral cavity. Herein, we describe a case of a 76-year-old Greek man with nasal obstruction and an extensive painful necrotic ulcer with ragged borders on the left distal portion of the soft palate and palatine tonsil of 4-months duration. After an initial non-diagnostic biopsy from the nasopharynx, a second incisional biopsy from the palatal lesions was performed. Histopathology was suggestive of an angiocentric lymphoproliferative neoplasm and immunohistochemical examination and in situ hybridization for EBV RNA led to a final diagnosis of ENKTL-NT. The patient was placed under combined chemotherapy and radiotherapy and no recurrence has been noted. Additionally, a retrospective review of the cases in the English literature with an established diagnosis of ENTKL-NT between 2000 and 2019, based on the latest WHO classification of Head and Neck tumors, is performed. © 2020, Springer Science+Business Media, LLC, part of Springer Nature

    E-Cigarette and palatal ulcer: a possible relationship?

    No full text
    Tobacco smoking is a major public health issue with far-reaching implications on the global economy. Electronic cigarettes are advertised as a new promising cessation treatment that can gratify the behavioural aspects of smoking. However, there are still many unanswered questions regarding e-cigarette’s safety and effects on general and oral health. We report a case of a 68-year-old Caucasian male patient with a large ulcerative lesion on the hard palate that was possibly associated with the use of an electronic cigarette. © 2020 The British Association of Oral Surgeons and John Wiley &amp; Sons Lt

    Lichenoid lesions of the upper lip: A retrospective study of 24 cases

    No full text
    Background: Lichenoid lesions of the upper labial mucosa, without other oral or extraoral manifestations seem to be rare. The clinicopathologic features of 24 such cases are presented and the pertinent literature is reviewed. Materials and Methods: 24 Caucasian patients that clinically presented lichenoid features on the upper labial mucosa, with or without lichenoid lesions on the adjacent gingiva, were included in the study. Clinical features were extracted from the patients’ records, while dental plaque/calculus accumulation and composite resin restorations of the adjacent teeth were recorded. Four cases where an incisional biopsy was performed were further evaluated. Results: There were 8 males and 16 females, with a mean age of 62.7 years. 64.2% were under hypertensive therapy. In 13 cases gingival involvement was noticed, 16 cases exhibited calculus deposition, while 6 cases presented with composite resin fillings of the adjacent teeth. In 4 cases an incisional biopsy was performed showing features of lichenoid reaction. In 37.5% significant improvement was observed after topical treatment with corticosteroids and antimicrobial agents. Conclusions: Lichenoid lesions of the upper lip may represent a distinct variety of oral lichenoid lesions, but as the number of cases reported so far is too small for definite conclusions on pathogenesis and management to be made, a long-term follow-up is mandatory. © 2018, Medicina Oral S.L.
