the introduction of l. vannamei to iran was initiated when high mortality occurred in shrimp farms of abadan in  2002 then in bushehr during summer of 2004.. inspection of l. vannamei for infectious agents , specially virus and  bacteria and relationship between them were the main objectives of this study. therefore about 240 samples consisting  of shrimps of l. vannamei were collected from far...

"Fairy rings" resulting from fungus-stimulated plant growth occur all over the world. In 2010, 2-azahypoxanthine (AHX) from a fungus Lepista sordida was identified as the "fairy" that stimulates plant growth. Furthermore, 2-aza-8-oxohypoxanthine (AOH) was isolated as a common metabolite of AHX in plants, and the endogenous existence of AHX and AOH in plants was proved. The structure of AHX allo...

Fairy tales, folktales and more generally children stories have lately attracted the Natural Language Processing (NLP) community. As such, very few corpora exist and linguistic resources are lacking. The work presented in this paper aims at filling this gap by presenting a syntactically and semantically annotated corpus. It focuses on the linguistic analysis of a Fairy Tales Corpus, and provide...

22 23 The evolution of fairy tales often involves complex interactions between oral and 24 literary traditions, which can be difficult to tease apart when investigating their 25 origins. Here, we show how computer-assisted stemmatology can be productively 26 applied to this problem, focusing on a long-standing controversy in fairy tale 27 scholarship: did Little Red Riding Hood originate as an ...

Abstract The effects of banana shrimp Fenneropenaeus merguiensis stocking density on water quality, growth performance, survival rate and body composition was assessed in a biofloc system with limited exchange. study conducted for 32 days an average larvae weight 10 ± 0.85 mg fiberglass tanks containing 120 L at four densities. Five experimental treatments consisted control (density 1000 shrimp...

Mantis shrimps (Crustacea: Stomatopoda) are potential aquaculture species as they are constantly fished from the wild to satisfy demands of the seafood industry. Breeding capacity of mantis shrimps in captivity is scarce and implies a gap in this area to achieve successful aquaculture practices for this species. A preliminary observation was conducted with locally obtained mantis shrimps Miyake...

In Namibia of southwestern Africa, the sparse grasslands that develop on deep sandy soils under rainfall between 50 and 100 mm per annum are punctuated by thousands of quasi-circular bare spots, usually surrounded by a ring of taller grass. The causes of these so-called "fairy circles" are unknown, although a number of hypotheses have been proposed. This paper provides a more complete descripti...

Male secondary sexual characters can provide females with information regarding the fertilizing capacity of a male’s sperm. In some fishes and birds, intense nuptial coloration is correlated with male fertilizing capacity, but no mechanistic link between coloration and sperm quality has been established. One plausible mechanism is that carotenoid pigments, which color skin and feathers in many ...
