Institutional settings play a key role in shaping land cover and land use. Our goal was to understand the effects of institutional changes on agricultural land abandonment in different countries of Eastern Europe and the former Soviet Union after the collapse of socialism. We studied ∼273 800 km2 (eight Landsat footprints) within one agro-ecological zone stretching across Poland, Belarus, Latvi...

River deltas grow in large part through repeated cycles of lobe construction and channel avulsion. Understanding avulsion cycles is important for coastal restoration and ecology, land management, and flood hazard mitigation. Emerging theories suggest that river avulsions on lowland deltas are controlled by backwater hydrodynamics; however, our knowledge of backwater-controlled avulsion cycles i...

Preexisting wells and well bores are high-permeability pathways through the crust, and as such present zones of elevated risk to CO2 storage projects. Although current well closure and abandonment technology appears sufficient to contain CO2 at most sites, individual wells may suffer from a variety of factors that limit their integrity, including improper cementation, improper plugging, overpre...

Møller and co-workers (Møller et al. 2007) observe an ‘elevated frequency of abnormalities in barn swallows (Hirundo rustica) at Chernobyl’ and ‘can think of no alternative explanations other than exposure to radiation that can have caused the observed patterns’. However, an obvious alternative hypothesis (e.g. Pikulik & Plenin 1994) is that apparent impacts on birds may be due to ecosystem cha...

Access abandonment after arteriovenous (AV) fistula (AVF) or graft (AVG) creation can pose clinical challenges for patients with end-stage renal disease. Our objective was to track AV access and identify factors that affect its rate. A single institutional database queried all AVF/AVG creations from 2014 2020. Demographics, comorbidities, outcomes were collected. defined as an no longer used in...

Introduction: Lichen diversity, community structure, composition and species abundance have been used as indicators of the integrity ecological continuity tropical forest ecosystems. Objectives: To assess corticolous lichen composition, importance three forested stands differing in time abandonment how passive restoration influences assemblage. Methods: We surveyed individual lichens on tree st...

OBJECTIVE Analyze the profile and outcome of children with rhabdomyosarcoma from a pediatric-oncology unit. DESIGN Retrospective analysis of case records over 23 years (1990-2012). Setting Government-run, tertiary-care, university hospital in Northern India. PARTICIPANTS 159 children (<12-years) with a diagnosis of rhabdomyosarcoma were enrolled. The median age was 4 years; 13% were infan...
