anastrepha bezzii (diptera: tephritidae) larvae are common inside fruits of sterculia chicha (malvaceae) in minas gerais state, brazil. the seed dormancy and attack by a. bezzii of the native species s.chicha can be detrimental to seed germination and thus the natural spread of this plant. the objectives of the current study were to compare ecological observations of a. bezzii and s. chicha in ...

wych elm (ulmus glabra hudson) is one of the forest species in hyrcanian forests of iran and considered as threatened species due to its narrow ecological range, over-exploitation, as well as dutch elm disease. in order to evaluate the possibility of cryopreservation of ulmus glabra seeds for long-term preservation, seeds were collected from natural habitats and three pre-treatment methods incl...

We investigated how foragers are activated in colonies of the red harvester ant, Pogonomyrmex barbatus. Each day, a harvester ant forager makes many trips out of the nest to gather seeds and bring them back to the nest. The rate at which foragers return to the nest is linked to food availability: when food is easy to find, foragers return more quickly. We examined how the return of successful a...

Business matching and collaboration support systems are useful, in particular for small-and-medium sized companies. Most of them developed so far are based on the server-client architecture and provide their services on Web servers. They require special administrative facilities, ask users to upload their data for matching between business needs and seeds, and leave to themselves peer-to-peer c...

Novel vesicles that accumulate large amounts of proprotein precursors of storage proteins were purified from maturing pumpkin seeds. These vesicles were designated precursor-accumulating (PAC) vesicles and had diameters of 200 to 400 nm. They contained an electron-dense core of storage proteins surrounded by an electron-translucent layer, and some vesicles also contained small vesicle-like stru...

Detecting opinion relation is a crucial step for fine-gained opinion summarization. A valid opinion relation has three requirements: a correct opinion word, a correct opinion target and the linking relation between them. Previous works prone to only verifying two of these requirements for opinion extraction, while leave the other requirement unverified. This could inevitably introduce noise ter...
