Adverse weather conditions can cause deterioration of wireless channels, leading to reduced link capacities. Unlike in other types of networks, in radio-based wireless mesh networks, the link capacities depend not only on the prevailing conditions, but also on interfering transmissions, as well as the transmission power and modulation and coding schemes used. This leads to increased difficulty in Adverse weather conditions can cause deterioration of wireless channels, leading to reduced link capacities.

The EU's farmers are no longer required to produce commodities to receive direct payments as long as they keep their land in good condition. Some believe this is bad for development because it encourages passive farming. We evaluate, using a real options approach, the implications of decoupled payments for the desirability and optimal timing of agricultural land development when considering sunk i

Birds, and especially long-distance migrants, are excellent indicators of climate-induced phenological change. Advanced spring arrival is a typical response reported in a great number of species. Earlier arrival can lead to e.g. earlier egg-laying and thus have potentially great fitness consequences. Studies have suggested that certain aspects of avian life-history can predict a likely response to

Biological responses to climate change have been widely documented across taxa and regions, but it remains unclear whether species are maintaining a good match between phenotype and environment, i.e. whether observed trait changes are adaptive. Here we reviewed 10,090 abstracts and extracted data from 71 studies reported in 58 relevant publications, to assess quantitatively whether phenotypic trai

The principle aim of the study is to describe, analyze and problemize the ways in which television science documentaries (within a public service context) discursively represent scientific theories, research results and conclusions about the origins of human nature and the causes of human behavior. The study covers 25 programs broadcasted by SVT and UR during a period of four years, 2002-2005, and

As requirements regarding energy efficiency are getting tougher, buildings in the arctic, as well as the rest of the world, need to be more energy efficient without compromising a good indoor climate. This article presents measured moisture supply and occupancy level in a Swedish arctic multi-family apartment block. Measurements were done over 1 year every 30 minutes in a building consisting of 51

Growing research on social capital and health has fuelled the debate on whether there is a place effect on health. A central question is whether health inequality between places is due to differences in the composition of people living in these places (compositional effect) or differences in the local social and physical environments (contextual effects). Despite extensive use of multilevel approa

Purpose To investigate the accuracy, reproducibility and sensitivity to respiratory gating, field strength and ventricle segmentation of hemodynamic force quantification in the left and right ventricles of the heart (LV and RV) using 4D-flow magnetic resonance imaging (MRI), and to provide free hemodynamic force analysis software. Materials and methods A pulsatile flow phantom was imaged using 4D

This paper examines the bus rapid transit (BRT) legacies of mega sporting events (MSEs) held in the Global South cities of Cape Town and Rio de Janeiro. It discusses the extent to which these transport systems have been operationally sustainable, post-MSE; in other words, their ability to be maintained at a certain rate or level and hence their ability to act as public good as planned and accordin

A robust water supply system is significant to the local ecosystem of riparian vegetation in the arid basin. Considering the elasticity and relative importance of ecological water use in different regions of the basin, this study defines the ecological water rights on a multi-year scale, divides the priority of those rights based on the ecological network, and proposes a rights allocation method.

Particle separation is one of the fundamental processes in wastewater treatment and a good understanding of the basic separation mechanisms ? sedimentation, flotation and filtration ? is critical in the design of wastewater treatment systems. Upgrading of treatment plants for enhanced primary treatment and effluent polishing are current examples of applications where effective, high-rate separatio
