when shareholders have agreement about divestiture of company’s share in stock exchange, they decide to change and improve their business ownership structure and the presence of a large shareholder to help divestiture. the present study was aimed to investigate the effect of presence of large shareholder to tends firm to divestiture by a new approach. for this purpose, the propensity score a sa...

The resin blocks are mounted on a motorized microtome. The microtome has to be modified to allow the block holder to reproducibly come to rest at a "photoposition" after each cut. E.g., the apparatus we operate in Vienna has its photoposition at the upper stopping point of the block holder excursion of a rotary microtome (Microtec CUT 4060E, microTec Laborgeräte GmbH). It is reproducibly reache...

Can institutional stock sales influence firm governance? Theory suggests that informed selling is likely to depress prices and disperse shareholding. Combined, both effects can influence firm governance by facilitating takeovers. I formalize this hypothesis and test its predictions on firms that undertake large acquisitions. Using acquisitions to identify firms with potential agency problems, I...

BACKGROUND Adhesive tape is commonly used to secure the endotracheal tube (ETT) in anesthesia and intensive-care settings. OBJECTIVE To determine the force required to extubate when the ETT is secured with adhesive tape or commercially available ETT holders. METHODS We orally intubated a simulation manikin with a standard 8.0-mm inner-diameter ETT, inflated the cuff to 20 cm H(2)O, and mea...

there are many parameters that affect the sheet hydroforming process such as fluid pressure, material properties, interfacial friction between blank and tool surfaces, etc. in this paper, a fem-based taguchi method is used to determine the effects of forming parameters on the quality of part formability in the process of hydrodynamic deep drawing assisted by radial pressure. four important form...

the aim of this paper is to develop a systematic method to analyze the effects of forming parameters on the quality of part formability and determine the optimal combination of the forming parameters for the sheet hydroforming process. in this paper, the effects of four important process parameters namely fluid pressure, friction coefficient at blank/punch interface, gap between die rim block a...

Most wireless systems receive a license that gives them exclusive access to a block of spectrum. Exclusivity guarantees adequate quality of service, but it also leads to inefficient use of spectrum. Even when the license holder is idle, no other device can use the spectrum. This paper explores an alternative paradigm for secondary access to spectrum, where a secondary device can transmit when a...
