This study examines the composition and activity of the planktonic community during the polar night in the high Arctic Kongsfjord, Svalbard. Our results are the first published evidence of bioluminescence among zooplankton during the Arctic polar night. The observations were collected by a bathyphotometer detecting bioluminescence, integrated into an autonomous underwater vehicle, to determine ...

1 Aim of This research is a Strategic analysis of seaports using multiple-criteria decision-making methods. At first, the strengths, weaknesses, opportunities and threats of Iranian seaports has been extracted from literature. Then, with respect to the importance concluded from LIKRET questionnaire distributed between experts (taking the views of the experts and specialist), five high importanc...

A bow-mounted surface pushnet and an obliquely towed plankton net were compared to evaluate gear efficiency and effectiveness in collecting larval fishes under daytime and nighttime conditions. The diadromous species targeted were striped bass Morone saxatilis, white perch, Morone americana, and river herring Alosa sp. We sampled the lower Roanoke River, North Carolina, from March through June ...

The development of Diapterus peruvianus (Sauvage 1879) is based on 60 larvae collected in superficial tows made in Bahía Concepción, and on 16 pre-juvenile and juvenile organisms collected in Bahía de La Paz, B. C. S., México, using a standard plankton net and a rectangular epibenthonic net, respectively. Larvae of D. peruvianus show three large blotches on the dorsum of the gut that can fuse t...

E-government has become an important phenomenon which attracted every country toward itself. However e-government is facing challenges which have significant effects on its performance. In order to overcome these challenges good strategies are inevitable for the e-government implementation. In this paper we analyzed Saudi Arabia's e-government using strengths, weaknesses, opportunities and...

cientists have discovered a new function for amyloid precursor protein (APP), a protein linked to Alzheimer’s disease. The finding may reveal how APP gets mixed up with the enzymes that make it go bad. APP has an evil reputation. The and secretases transform it into amyloidpeptide, a component of the plaques that riddle the brain in Alzheimer’s disease. Previous work by Larry Goldstein (Univesi...

The second micronekton inter-calibration experiment (MIE-2) was carried out in the coastal area off southeastern Hokkaido Island, Japan, during September 23–October 3, 2005. Comparative tows were made at four stations situated over the upper continental slope with bottom depths of approximately 500 m (Fig. 3.1). This area is strongly influenced by the coastal branch of the Oyashio Current (Kono...

Trace metal clean plankton tows, river samples, aerosol leachates, and porewater samples from the Amazon River system were measured for their iron isotopic composition. The overall isotopic range observed was 1.5‰ with Fe isotopic variability observed between different types of tributaries. Dissolved Fe and suspended load Fe from two main channel sites were isotopically similar (≈ −0.1 to −0.3‰...
