BACKGROUND E. faecalis is the predominant micro-organism recovered from root canal of the teeth where previous endodontic treatment has failed. Thorough debridement and complete elimination of micro-organisms are objectives of an effective endodontic treatment. For many years, intracanal irrigants have been used as an adjunct to enhance antimicrobial effect of cleaning and shaping in endodontic...

In this paper we present a generative model entitled the Author Perspective Model for the classification of deontic modality in event mentions. In the model modals, adverbials, and predicates associated with an event mention are generated by either a topic or author perspective where the author perspective is one of the three high level categories of deontic modality. We train the model with da...

Canola (Brassica napus L.) is one of the important sources of vegetable oils and protein-rich meals. Canola ranks third in global production of oilseed crops and fifth among economically important crop next to wheat, rice, maize, and cotton. The present work was undertaken with the aim to investigate the effect of Ethylmethyl sulphonate (EMS) on the yield contributing characters of brassica nap...

Salmonella serovars have been associated with the majority of foodborne illness outbreaks involving tomatoes, and E. coli O157:H7 has caused outbreaks involving other fresh produce. Contamination by both pathogens has been thought to originate from all points of the growing and distribution process. To determine if Salmonella serovar Typhimurium and E. coli O157:H7 could move to the mature toma...

Crassocephalum crepidioides, Conyza canadensis, and Ageratum conyzoides are alien annuals naturalized in China, which produce a large number of viable seeds every year. They widely grow in Xishuangbanna, becoming troublesome weeds that compete with crops for water and nutrients. As seed germination is among the most important life-stages which contribute to plant distribution and invasiveness, ...
