Wireless sensor networks have emerged as a fastgrowing technology that has enabled us to monitor physical and environmental states. As of yet these valuable sensor networks have been bound to terrestrial terrains; however, seventy percent of the Earth’s surface is covered by enormous bodies of water: oceans, seas and rivers. Most of this territory remains unchartered, and this primarily gave a ...

T HE discrete memoryless broadcast channel (%P(YJlX), 94 x 3) consists of three finite sets % ., 9, % and a probability transition matrixp(y,zjx). Let p,(ylx) andp,(zIx) be the two marginals of p(y,zlx), and let P, and P2 denote the discrete memoryless channels with probability transition matrices p&y Ix) and pz(zlx), respectively. Recall the following three relations between P, and P2. Definit...

We observed the behavior and ecology of Chaetodon capistratus infected and uninfected with the ectoparasitic isopod Anilocra chaetodontis to assess whether there may be parasite induced alterations in host biology, host defenses against infection, and/or pathology related to infection. We also examined habitat related differences in infection rates. Infected fish had higher rates of interaction...

This study aims at finding out if households or organizations are faster in their acceptance of a technological innovation. The object of this study is digital terrestrial television (DTT), specifically the implementation of DTT in Denmark. The theoretical framework is diffusion of innovation theory. Three surveys were carried out for both households and organizations. Based on the surveys, the...

As digital television matures, applications which utilize data embedded in the broadcast television signal are likely to be an important feature of the new medium. This paper explores some of the issues involved in the implementation of systems for the utilization of data which accompanies digital television's video and audio content. Chief among these issues are those which

Chitinaceous organisms have been found to ingest microplastic; however, a standardised, validated, and time- cost-efficient method for dissolving these without affecting microplastic particles is still required. This study tested four protocols with chitin exoskeleton: 1) potassium hydroxide (KOH) + chitinase, 2) Creon® 3) hydrogen peroxide (H2O2) and, 4) Nitric Acid (HNO3) (H2O2). The effects ...

The present study was motivated by the paucity of reports on cellular internalization of ingested titanium dioxide (TiO(2)) nanoparticles (nano-TiO(2)). The model invertebrate (Porcellio scaber, Isopoda, Crustacea) was exposed to food dosed with nano-TiO(2) containing 100, 1,000, 3,000, or 5,000 µg nano-TiO(2) per gram of food. After 14 d of exposure, the amount of Ti in the entire body was ana...

In previous studies we detected lower species richness and lower Hg sensitivity of the bacteria present in egested guts of Porcellio scaber (Crustacea, Isopoda) from chronically Hg polluted than from unpolluted environment. Basis for such results were further investigated by sequencing of 16S rRNA genes of mercury-resistant (Hgr) isolates and clone libraries. We observed up to 385 times higher ...
