The authors investigated the effects of di-n-butyl phthalate (DBP) on root physiology and rhizosphere microbial communities of cucumber seedlings (sativus L. cv Jinyan No. 4). Root protein content and root activity were observed to decrease. From the ultrastructural micrographs, visible impact on the mitochondria, endoplasmic reticulum and vacuole were(More)
Phthalic acid esters (PAEs) are one kind of persistent organic pollutants. This study was conducted to investigate the effects of diethylphthalate (DEP) and di(2-ethyl)hexylphthalate (DEHP) with different concentrations (0, 30, 50, 100, and 200 mg L(-1)) on early seedling growth of Cucumis sativus L. Physiological, biochemical, and ultrastructure of(More)
Due to the independence of the domain knowledge, general search engine has "theme drift" problem in the search of domain knowledge. Topic specific search engine offers a faster, and more accurate web resources retrieval service, and a good web page sorting algorithm can improve user experience. In this paper, we proposed a new sorting algorithm for topic(More)
With the continuous development of the information technology, ontology has been widely applied to various fields. Ontology has become an advanced technology in artificial intelligence and knowledge engineering, playing an increasingly important role in knowledge representation, knowledge acquisition and ontology application. As the base of ontology(More)
Nowadays, the scale of wireless sensor network is getting bigger, and the data in transmission is increasing. Due to the amount of data and unstable network status, leading to the high loss rate of data packet, so part of important data may not be sent in time, especially in the network which has real-time requirements. Currently the research work on the(More)
OBJECTIVE To explore the relationship between dopamine β-hydroxylase gene polymorphisms and Parkinson's disease (PD) in Uygurs and Hans populations of Xinjiang. METHODS The polymorphisms of DBH gene were determined by polymerase chain-reaction restriction fragment length polymorphism (PCR-RFLP) in 239 PD patients (including 100 Uygurs and 141 Hans) and(More)
