Introduction Many infectious diseases are sensitive to climatic changes; specifically, flooding. This systematic literature review aimed to strengthen the quality and completeness of evidence on infectious diseases following flooding, relevant to Europe. Methods A systematic literature review from 2004-2012 was performed. Focused searches of the following databases were conducted: Medline, Scop...

Roots of 1.5-year-old ;Woodard' rabbiteye blueberry plants (Vaccinium ashei Reade) were flooded in containers or maintained at container capacity over a 5-day period. Carbon assimilation, and stomatal and residual conductances were monitored on one fully expanded shoot/plant using an open flow gas analysis system. Quantum yield was calculated from light response curves. Carbon assimilation and ...

There is a wide usage of mobiles anywhere and anytime to access the multimedia data. Thus there will be more oppurtunity for wireless adhoc networks. Because, comparing with the wired networks, wireless networks provides low cost and easy accesibility. But the main disadvantage for Consumer electronic devices were generally operate on limited battery power and therfore are vulnerable to securit...

After the flood disaster in 1953 in the southwestern part of the Netherlands, Van Dantzig tried to solve the economic decision problem concerning the optimal height of dikes. His solution has a fixed probability of flooding after each investment. However, when there is economic growth, not the probability of flooding but the expected yearly loss by flooding is the key variable in the real optim...

Black willow (Salix nigra) cuttings are used for streambank stabilization where they are subjected to a range of soil moisture conditions including flooding. Flooding has been shown to adversely impact cutting performance, and improved understanding of natural adaptations to flooding might suggest handling and planting techniques to enhance success. However, data assessing the root aeration in ...

We propose Fast Flooding in Power Save Mode (FFPSM), a modification of IEEE 802.11 power save mode operation for Mobile Ad hoc NETworks (MANET). The previous works for the power save mode operation usually focused on shortening the duration of the awake state to minimize the power consumption of mobile nodes. We observed that the longer sleeping period results in seriously long delivery latency...

Flooding is one of the most hazardous natural disasters, and there are several levels of flooding. Recently, research on flood-tolerant rice plants revealed that some rice varieties have evolved to overcome two different flood types, 'flash flood' and 'deepwater flood', using two different mechanisms, and their molecular mechanisms were determined. During flash flooding, the tolerant plants tha...

Many protocols for Mobile Ad-hoc Networks propose construction of routes reactively using flooding. The advantage hereof is that no prior assumption of the network topology is required in order to provide routing between any pair of nodes in the network. In mobile networks, where the topology may be subject to frequent changes, this is a particularly attractive property. In this paper, we inves...

Storm surges, leading to catastrophic coastal flooding, are amongst the most feared natural hazards due to the high population densities and economic importance of littoral areas. Using the Central Mediterranean Sea as a model system, we provide strong evidence for enhanced periods of storminess leading to coastal flooding during the last 4500 years. We show that long-term correlations can be d...

BACKGROUND AND AIMS Despite concerns about the impact of rising sea levels and storm surge events on coastal ecosystems, there is remarkably little information on the response of terrestrial coastal plant species to seawater inundation. The aim of this study was to elucidate responses of a glycophyte (white clover, Trifolium repens) to short-duration soil flooding by seawater and recovery follo...
