background: in this paper, paleoparasitological findings from rodent excrements ob-tained from chehrabad salt mine archeological site located in northwest of iran are demonstrated and discussed. methods : chehrabad salt mine archeological site located in northwest of iran, dated to the achaemenid (mid 1st mill. bce) and to sassanid (3rd cent. - 7th cent. ce) period, is a unique study area to in...

At the international level, there is an increasing awareness that many of the environmental problems that our civilisation has brought upon itself are either focused on the shorelines or most obvious in their vicinity. Fertiliser run-off from agricultural lands produces eutrophication of coastal waters, marine litter washes up on Norway’s otherwise flawless beaches, and disoriented whales as we...

background: cutaneous leishmaniasis due to leishmania major has become a hot topic in iran. the objective of this study was to determine some ecological aspects of sand flies in the study area. methods: sand flies were collected biweekly from indoors and outdoors fixed places in the selected villages, using 30 sticky paper traps from the beginning to the end of the active season of 2006 in kerm...

introduction: cutaneous leishmaniasis is a parasitological disease that is spread in many tropical and subtropical areas in world. this disease transmitted by female sand flies. it is clear that knowledge on sand flies ecology has the main role to planning of control of cl. this study was carried out for determination of cl vectors, in ghanavat district in qom province during 2012. material and...

background phlebotomus papatasi and p. salehi are reported as vectors of cutaneous leishmaniasis in southeast of iran. seasonal activity of these species is different in zoogeographical zones and must be known well for better management of the disease. objectives to determine the nocturnal activity of sand flies and their leptomonad infection rates. materials and methods a cross-sectional study...

A Burrows-Wheeler Compressor breaks input into blocks, quickly makes each more compressible, and compresses the modified block with a simple arithmetic or Huffman compressor. We propose an error-resilient Inverse Burrows-Wheeler Compressor. It uses a small amount of overhead alongside output from an ordinary BWT and MTF. It is also size-competitive with BZIP, a popular Burrows-Wheeler compressor.

Like many other species of petrel, blue petrel (Halobaena caerulea) are able to return to their nest burrows at night in complete darkness. Since petrels have a well-developed olfactory system, we carried out an experiment to test whether blue petrels use olfaction to localise their nest burrows. Incubating birds were injected intranasally with a zinc sulphate solution, which reversibly impairs...
