Xiong proved that if f : I ! I is any map of the unit interval I , then the depth of the centre of f is at most 2, and Ye proved that for any map f : T ! T of a finite tree T , the depth of the centre of f is at most 3. It is natural to ask whether the result can be generalized to maps of dendrites. In this note, we show that there is a dendrite D such that for any countable ordinal number 1⁄2 ...

In this paper we provide a simple characterization of the dominance in two classes of continuous triangular norms. In particular, we solve the dominance of (i) ordinal sum t-norms that use the Łukasiewicz t-norm as the only summand operation and (ii) ordinal sum t-norms that use the product t-norm as the only summand operation. In both cases, the dominance relation is characterized by a simple ...

If δ is an ordinal, we denote by C(δ) the class of all cardinal sequences of length δ of locally compact scattered (in short: LCS) spaces. If λ is an infinite cardinal, we write Cλ(δ) = {s ∈ C(δ) : s(0) = λ = min[s(ζ) : ζ < δ]}. An LCS space X is called Cλ(δ)-universal if SEQ(X) ∈ Cλ(δ), and for each sequence s ∈ Cλ(δ) there is an open subspace Y of X with SEQ(Y ) = s. We show that • there is a...

background: cervical spine sustains most of thevertebral column injuries, among other injuries, the disc degeneration and damage that lead to replacement of the damaged disc with cage or artificial disc. methods: the c4 to c6 vertebrae of a normal subject and a person with interbody fusion cage were 3d modelled and then analyzed using finite element method. the results of maximum stress and str...

In this paper we examine middle managers’ struggle over their subject position as strategists in the context of participative strategy processes. Based on a longitudinal case study company undertaking an Open Strategy process, show how wider inclusion front-line employees developing new undermines traditional managers. these findings, develop process model depicting recursive dynamics struggles...

Critical Discourse Analysis uncovers the relationship between discourse, ideology, and power. This study investigated and analyzed contents, social relations, and subject positions in conversations of four popular advanced ELT textbooks. The findings indicated that for contents, giving/asking for information and interaction were outstandingly significant. Regarding social relations, friend was ...
