Formability of Tailor Welded Blank (TWB) is an important parameter which limits this kind of blanks usage. A forming criterion for tailor welded blank is presented based on the analytical model in this research. This criterion suggests Limit Strength Ratio (LSR) and Limit Thickness Ratio (LTR) for forming limit of TWB. When thickness ratio or strength ratio in tailor welded blank is greater tha...

BACKGROUND/PURPOSE Dental rotary instruments can be applied in multiple conditions of canals, but unpredictable fatigue fracture may happen. This study evaluated the fatigue lives of two batches of nickel-titanium (NiTi) dental rotary files operating in clinically simulated root canals. METHODS Single-step cyclic fatigue tests were carried out to assess the performance of two batches of NiTi ...

BACKGROUND Beliefs that it is unacceptable to experience or express negative emotions have been found to be associated with various clinical problems. It is unclear how such beliefs, which could be viewed as a form of unhelpful perfectionism about emotions, may contribute to symptomatology. AIMS This study investigated two hypotheses: a) greater endorsement of beliefs about the unacceptabilit...

The Fatigue Symptom Inventory has been used extensively to assess and measure fatigue in a number of clinical populations. The purpose of the present study was to further establish its utility by examining its operating characteristics and determining the optimal cutoff score for identifying clinically meaningful fatigue. The MOS 36-Item Short Form Vitality scale, a measure widely used to ident...

Greater transparency and disclosure of bank activities will not prevent future banking crises unless appropriate monetary, fiscal, and regulatory policies are also adopted. Nonetheless, greater disclosure of banking problems can reduce the costs of banking crises, even if transparency is not a panacea for preventing banking crises. key words: Disclosure, Transparency, Banking Crisis This paper ...
