The Tool for Exploratory Landscape Scenario Analyses (TELSA) is a spatially explicit model of vegetation succession, natural disturbances, and forest management activities. TELSA is a strategic planning tool designed to support adaptive management by projecting the consequences of alternative scenarios at the scale of landscape units (i.e. 10 000–200 000 ha) over time frames of decades to centu...

A new family of iterative methods, the family of EN-like methods, is introduced, and its relationship to other methods is investigated. The complexity and convergence behavior of the new methods as well as their restarted and truncated versions are examined. The methods are also shown to be suitable in the context of inner/outer iteration schemes. Their adaptive versions are included into a rob...

Rising atmospheric carbon dioxide (CO2) concentration and global warming could impact growth of citrus trees. Five 2-year-old Ambersweet orange trees on Swingle citrumelo rootstocks were transplanted into soil containers in two temperature-gradient greenhouses on 9 August 1994 at Gainesville, FL, USA. Either 360 or 720 mmol (CO2) mol 1 (air) was maintained in the greenhouses. Two containers wer...

The behavioural response to infection is well organized and may enhance disease resistance and facilitate recovery, but the behaviour of pigs with an acute respiratory infection has not been assessed. Therefore, the purpose of this study was to evaluate behaviour of pigs inoculated with Mycoplasma hyopneumoniae (Mh) and porcine reproductive and respiratory syndrome virus (PRRSV). Sixty-four pig...

Dogs show considerable variation in morphology, genetics and behaviour caused by long periods of artificial selection. This is evident in the large number of breeds we have today. Behavioural differences among breeds have often been regarded as remnants from past selection during the breeds’ origin. However, the selection in many breeds has, during the last decades, gone through great changes, ...

Increasing atmospheric carbon dioxide (CO2) likely will affect future water requirements of most plants, including agricultural crops. This research quantifies such effects on the energy balance and evapotranspiration (ET) of sorghum (Sorghum bicolor (L.) Möench, a C4 grain crop) using a residual energy balance approach. During the summer and autumn of 1998 and 1999, sorghum was grown under fre...

The performances of 3, 2 and 1.5 mm gap RPCs operated with a heavy, environmentally safe industrial gas, C 2 H 2 F 4 , have been tested at cosmic ray fluxes. Emphasis is given to the study of avalanche-to-streamer transition. ( 1998 Elsevier Science B.V. All rights reserved. Resistive Plate Chambers will be used as the LVL1 muon trigger detector in the barrel region (DgD(1) of the ATLAS experim...

Disturbance and house soiling during the night are common problems faced by the new puppy dog owner. They may result as consequence of a mismatch between the developmental status of the puppy and its new environment and/or separation distress in a typically social animal. The aim of this study was to examine the effect of Dog Appeasing Pheromone (DAP, Ceva Santé Animale) as well as a range of o...

A new reconstruction method has been developed for material-selective tomography that allows non-negativity and maximum density constraints to be enforced on each pixel. In addition, uncertainty in the projection data is appropriately accounted for . Results of applying the constrained reconstruction to simulated data demonstrate significant improvements over unconstrained reconstructions. Dual...
