Results: Our sample size is too small to draw empirical conclusions about whether clickers alone improve grades, but subjectively there was a clear improvement in the classroom dynamic when using the clicker technology. The students were engaged and enjoyed the immediate feedback and resulting peer interaction. The instant feedback also enabled the professor to recognize and address a grammatic...

OBJECTIVE The risk factors of bladder cancer recurrence after transurethral resection of bladder tumor (TURBt) were poorly understood, especially in Chinese population. This study evaluated the potential risk factors of recurrence based on a Chinese population. MATERIALS AND METHODS A total of 698 patients that received TURBt procedure in our institute from 2000 to 2012 were recruited in this...

People tend to be overconfident when predicting their performance on a variety of physical and mental tasks (i.e., they predict they will perform better than they actually do). Such a pattern is commonly found in educational settings, in which many students greatly overestimate how well they will perform on exams. In particular, the lowest-performing students tend to show the greatest overconfi...

in the open-pit mining, one of the first decisions that must be made in production planning stage, after completing the design of final pit limits, is determining of the processing plant cut-off grade. since this grade has an essential effect on operations, choosing the optimum cut-off grade is of considerable importance. different goals may be used for determining optimum cut-off grade. one of...

i.p.s. hypergroups are canonical hypergroups such that$[forall(a,x),a+xni x]longrightarrow[a+x=x].$i.p.s. hypergroups were investigated in [1], [2], [3], [4] and it was proved thatif the order is less than 9, they are strongly canonical (see [13]). in this paperwe obtain the sequences of fuzzy sets and of join spaces determined (see [8])by all i.p.s. hypergroups of order seven. for the meaning ...

nano-hydroxyapatite/gelatin (nha/ge) microspheres are currently used in bone tissue engineering as bone filler. in this  study, the effect of fabrication process parameters on the particle size of nano-hydroxyapatite/gelatinmicrospheres was investigated. the nha/ge microspheres were fabricated using water in oil emulsion. in order to design an experimental design, a surface response model with ...

background : invasive ductal carcinoma is one of the most common type of tumors in females, constituting a single large group of breast cancers. there are various prognostic factors, of which tumor grade, size and axillary lymph node metastasis are among the important ones. fine needle aspiration cytology is a commonly used diagnostic technique in the initial evaluation of breast lumps. in the ...
