Inspired by recent work of Batanin and Berger on the homotopy theory of operads, a general monad-theoretic context for speaking about structures within structures is presented, and the problem of constructing the universal ambient structure containing the prescribed internal structure is studied. Following the work of Lack, these universal objects must be constructed from simplicial objects ari...

Objective: To review internal impingement of the shoulder. Design: Review article. Anatomic & Biomechanical Factors: Internal impingement is typically understood to be the impingement of the cuff on the posterior-superior labrum, with shoulder abduction and external rotation, a position seen in overhead athletes. While pinching of the cuff on the posterior labrum can be seen in normal subjects,...

uniaxial compressive strength (ucs) and internal friction coefficient (µ) are the most important strength parameters of rock. they could be determined either by laboratory tests or from empirical correlations. the laboratory analysis sometimes is not possible for many reasons. on the other hand, due to changes in rock compositions and properties, none of the correlations could be applied as an ...

during spring and summer of 2012, a disease characterized by panicle blight was observed on some pistachio (pistacia vera l.) trees grown in kerman province. eighteen isolates of a botryosphaeriaceae were obtained from affected panicles. based on morphological and molecular characteristics, isolates were identified as botrysphaeria dothidea. to our knowledge, this is the first report of b. doth...
