Two isolates of Staphylococcus xylosus (urease producer and non urease producer) were injected in mice at a dose of 2 × 108 colony-forming units (CFU) intraurethrally. Results showed that both isolates were able to colonize kidney and bladder of the injected mice, regardless of their urease production. Moreover, there were insignificant differences between the two groups. These results emphasized the pathogenicity of this bacteria in UTI.
152 sera were collected from healthy individuals residing A;-Haweja City were tested for antibody titers for brucella antigens by slide agglutination test

The paper generates its data from six M. A. dissertations from Nigerian University and equal number of the M. A. dissertations from Iraqi University to qualitatively and quantitatively investigate the contextual use of modality within the pragmatic perspective. The data analysis reveals that modality such as usuality, potentiality, necessity, probability and obligation in the dissertations encapsulates interpersonal and authorial voice in which the mean

It is a communicative strategy which enables speakers to soften the force of utterances or moderate the assertive force of utterances. It is resulted from different features such as uncertainty, doubt, tentativeness, ambiguity, neutrality, mitigation, and subjectivity. Hedging is used widely in TV debates to make utterances more acceptable to the interlocutors. Hedges are expressions used to communicate the speaker's weak commitment to information conveyed. The utterances in debates are often hedged because in an unhedged form might sound threatening to the addressees, and, therefore, be likely to be rejected.

A native speaker intuitively feels the difference between metonymy and i
