The article reviews the weldability of clad steel used for protection inner surface oil-and-gas pipelines from corrosion by different welding materials. It is indicated that during root pass stainless electrodes in one transition structures appear on interface two dissimelar metals. This process leads to formaion cracks. To reduce negative impact characteristics welded joints it recommended wel...

New diode structures without the field-oxide boundary across the p/n junction for ESD protection are proposed. A NMOS (PMOS) is especially inserted into the diode structure to form the NMOS-bounded (PMOS-bounded) diode, which is used to block the field oxide isolation across the p/n junction in the diode structure. The proposed N(P)MOSbounded diodes can provide more efficient ESD protection to ...

Given self-protection from an undesirable environmental externality, we examine. under several conditions, the efficiency properties of cooperative and noncooperative behavior. We demonstrate that if self-protection can transfer the externality to another agent, then noncooperative behavior will lead to overprotection. If self-protection filters or dilutes the externality, then noncooperation l...

i I I D B c A supraaortic arteries and, particularly, to carotid bifurcations [4-17] . We previously reported an angioplasty technique involving temporary occlusion of the internal carotid artery to prevent cerebral embolization during manipulation of ulcerated plaques [18]. The present article describes a new triple coaxial catheter system (Schneider [Europe] AG, Zurich, Switzerland) (Fig. 1 )...

Five selected China IT business incubators are studied with grounded theory, after coding the interview data, we establish the model of influence factors that affect IT business incubator’s incubation performance with dimensions of the external factor, the internal factor and the associated factor. The external factors that affect the incubation performance are institution and industry environm...
