abstract irregular extraction from agricultural wells around parishan lake, moreover fall of groundwater surface and water salty, would affect the level of lake water and move lake water into wells. in this study we have evaluated the externalities of extraction from agricultural wells around the lake. therefore feedback effect is considered between agricultural activity around the lake and lev...

The results of 501 day-case cataract extractions are presented. This is a safe way to manage an operation for which there will be an increased demand. Only 13% of these patients stated that they would have preferred to stay in hospital after surgery.

a simple, inexpensive and efficient method was used for extraction and determination of fexofenadine and levocetirizine with three–phase hollow fiber liquid-phase microextraction and high-performance liquid chromatography. several parameters influencing the extraction recoveries such as the nature of organic extraction solvent, ph of donor and acceptor phases, stirring rate, extraction time and...

Keyphrase extraction is the task of finding phrases that represent the important content of a document. The main aim of keyphrase extraction is to propose textual units that represent the most important topics developed in a document. The output keyphrases of automatic keyphrase extraction methods for test documents are typically evaluated by comparing them to manually assigned reference keyphr...

Systems which build on top of information extraction are typically challenged to extract knowledge that, while correct, is not yet well-known. We hypothesize that a good confidence measure for relational information has the property that such interesting information is found between information extracted with very high confidence and very low confidence. We discuss confidence estimation for the...

-------------------------------------------------------------------ABSTRACT----------------------------------------------------------------Nowadays various applications are available that claim to extract the correct information from such colored image databases which have different kinds of images and their own semantics. During information extraction based on the content of images various kin...

Background and objectives: Colchicum kurdicum (Bornm.) Stef. is a flowering perennial monocotyledon plant that has many important bioactive compounds especially colchicine and colchicine derivatives. In this study, the ultrasound-assisted acidic-solvent extraction method coupled with response-surface method was presented as the successful method for large scale extract...

We propose a static relation extraction task to complement biomedical information extraction approaches. We argue that static relations such as part-whole are implicitly involved in many common extraction settings, define a task setting making them explicit, and discuss their integration into previously proposed tasks and extraction methods. We further identify a specific static relation extrac...
