B814: Performance Evaluations of Potato Clones and Varieties in the Northeastern States - 1985

New potato clones and varieties must be tested against commercially accepted cultivars to determine If they possess advantages over existing varieties. Possible Improvements over the existing varieties could Include greater disease resistance or tolerance, higher yield, more uniform tuber size distribution, Improved storagability, good processing characteristics, etc. Often new cultivars are sought to fill local special-purpose needs. The cooperative potato variety trials reported In this bulletin were conducted to provide Information on the performance, adaptation, and performance stability of new potato clones under a wide range of geographic, climatic, soil, and cultural conditions. These tests are contributions to Regional Project NE-107 entitled, Breeding and Evaluation of New Potato Clones for the Northeast. The objectives of this regional project are: 1). To develop high quality, widely adapted, productive, pest resistant potato varieties for use In the northeast; 2). To determine regional performance, quality, and storage characteristics for promising potato clones and new varieties; 3). To evaluate promising clones and varieties for special-purpose needs such as pest outbreaks, processing, export, specialized market opportunities and/or production situations; 4). To develop management practices such as plant population, fertilizer rate, disease, weed, and Insect control strategies that will I Improve the yield and/or quality of promising clones. Data presented In this report primarily address objectives 2 and 3.https://digitalcommons.library.umaine.edu/aes_bulletin/1118/thumbnail.jp

B801: Performance Evaluations of Potato Clones and Varieties in the Northeastern States 1983

Cooperative potato clone and variety trials were conducted at 23 locations to determine field, storage, and processing behavior of selected clones and varieties grown under soil, climatic, and cultural management common to the potato growing areas of 13 cooperating states and the Province of New Brunswick, Canada. These tests are all contributions to Regional Project NE107 entitled, Breeding and Evaluation of New Potato Clones for the Northeast. The primary objective of this project is to determine clone stability over a wide range of soil, climate, and cultural conditions.https://digitalcommons.library.umaine.edu/aes_bulletin/1119/thumbnail.jp

Spatial ecology of closely related taxa: the case of the little shearwater complex in the North Atlantic Ocean

Este artículo contiene 21 páginas, 6 figuras, 5 tablas.Seabirds inhabiting vast water masses provide numerous examples where opposing phenomena, such as natal and breeding philopatry vs. vagility have dug cryptic taxonomic boundaries among closely related taxa. The taxonomy of little shearwaters of the North Atlantic Ocean (Little–Audubon’s shearwater complex, Puffinus assimilis–lherminieri) still remains unclear, and complementary information on non-breeding distributions and at-sea behaviour becomes essential to unravel divergent local adaptations to specific habitats. Using miniaturized light-level geolocators from seven study areas in the North Atlantic, we evaluate the spatial and habitat segregation, estimate the timing of their key life-cycle events and describe the at-sea behaviour of three taxa of these little shearwaters year-round to distinguish ecological patterns and specializations that could ultimately unravel potential lineage divergences. We also assess morphometric data from birds that were breeding at each study area to further discuss potential adaptations to specific habitats. Our results show that, while birds from different taxa segregated in space and habitats, they share ecological plasticity, similar annual phenology and diel foraging behaviour. These ecological inconsistencies, while defining the evolutionary stressors faced by these taxa, do not suggest the existence of three Evolutionary Significant Units. However, they confirm the recent evolutionary divergence among the three little shearwaters of the North Atlantic.We acknowledge the Ministerio de Economía y Competitividad (MINECO), the Fondos FEDER (CGL2009-11278/BOS, CGL2013-42585-P), the EU LIFE Programme (LIFE09 NAT/PT/000041) and the British Ornithologists’ Union for funding.RR was supported by postdoctoral contracts of the Juan de la Cierva (JCI-2012–11848) and PLEAMAR (2017/2349) programs from the Spanish MINECO and the European Maritime and Fisheries Fund (EMFF), respectively, VHP by a postdoctoral fellowship of Fundação para a Ciência e a Tecnologia (FCT; SFRH/BPD/85024/2012) and ZZ by a PhD grant (APIF-2012) from Universitat de Barcelona (Spain).Peer reviewe

DART : modèle physique 3D d'images de télédétection et du bilan radiatif de paysages urbains et naturels

Le modèle DART (Discrete Anisotropic Radiative Transfer) simule le transfert radiatif optique dans le système "Terre - Atmosphère", du visible à l'infrarouge thermique, pour des paysages urbains et naturels (e.g., forêts multi-espèces), avec atmosphère et relief. Ses deux principales sorties sont : - images de télédétection spatiale (i.e., réflectance ou température directionnels), pour toute direction solaire et de visée, altitude du capteur, résolution spatiale, etc. - Bilan radiatif 3-D. ce bilan est utilisé pour simuler la photosynthèse ainsi que les bilans d'énergie et de masse des surfaces terrestres. DART génère aussi des séries de simulations où certains paramètres (e.g., LAI, temps, longueur d'onde) varient, ce qui permet de créer des courbes spectrales et temporelles. De plus, il inverse les images de télédétection pour calculer certains paramètres biophysiques (e.g., LAI, taux de couverture). DART simule les paysages en tant que matrices 3-D de cellules parallélépipédiques qui contiennent de la matière turbide et/ou des éléments de surface opaques ou translucides dotés de propriétés optiques isotropes (i.e., lambertien) ou non (e.g., spéculaire). Ces propriétés peuvent être spécifiées par des bases de données spectrales ou via le couplage de DART avec le modèle foliaire PROSPECT. Une interface graphique gère la simulation du paysage et l'affichage des résultats (e.g., images, spectres). Validé lors de l'expérience RAMI, puis breveté en 2003, DART est désormais un outil très utile pour analyser et interpréter les images de télédétection.

Surgical treatment of aseptic forearm nonunion with plate and opposite bone graft strut. Autograft or allograft?

Purpose of the study: Adequate treatment of forearm nonunion should achieve both biological stimulation of the bone and mechanical stability. The use of bone graft could enhance the healing of a nonunion providing osteogenic, osteoconductive and osteoinductive stimulation and an optimal stability of the fixation. We retrospectively reviewed two cohorts of patients affected by forearm nonunion and treated with plate and opposite bone graft to determine whether the use of autograft versus allograft differs in terms of (1) rate of healing of the nonunion and (2) time of healing. Materials and methods: Thirty-four patients were treated for aseptic forearm nonunion with cortical graft strut with opposite plate and intercalary graft in case of segmental bone defect. In 20 patients an autograft harvest from the fibula (group A) and in 14 (group B) an allograft provided by the bone bank of our institution were used. Results: All the nonunions healed in a mean of four months in both groups, ranging from two to 12 months in group A and from three to ten months in group B. At the latest follow up forearm function and pain were satisfactory in both groups. Conclusion: The use of plate and opposite bone graft demonstrated to be effective in promoting the healing of forearm nonunions, without significant differences in terms of rate and time of healing in the two groups. Considering the higher surgical time and the comorbidity of the donor site, if a bone bank is available, we suggest to use homologous cortical bone strut graft with opposite plate and screw fixation for the treatment of aseptic forearm nonunion rather than autograft
