the main objective of this study is to swing krull intersection theorem in primary decomposition of rings and modules to the primary decomposition of soft rings and soft modules. to fulfill this aim several notions like soft prime ideals, soft maximal ideals, soft primary ideals, and soft radical ideals are introduced for a soft ring over a given unitary commutative ring. consequently, the p...

CMOS switches are one of the main components of today's analog circuits. Among the many types of non-idealities that can affect the performance of the switch, its leakage current is of utmost importance. In order to reduce the leakage current or equally increase the OFF resistance of any switch, a novel technique is presented in this paper. The proposed technique employs the body effect to incr...

We present and examine two cases of the dramatic hemostasis with SOFT COAG in general thoracic surgery. SOFT COAG is a coagulation mode unique to VIO electrosurgical units (ERBE Elektromedizin GmbH, Germany). This system regulates the temperature rise below boiling point without generating sparks, which is high enough to denature protein. In addition to clinical applications, this coagulation s...

In this paper, design, analysis and fabrication of a low loss capacitive RF MEMS shunt switch, which made on the coplanar waveguide transmission line and alumina substrate in the frequency band of 40-60 GHz, is presented. The CPW is designed to have 50Ω impedance matching on the alumina substrate. Then the desired switch is designed with appropriate dimensions. Afterward the important par...

Since the PCS needs to handle high power high voltage, the soft-switching topologies utilized in the design should have both ZVT and ZCT functions. A novel soft-switching topology that has both ZVT and ZCT functions is suggested. The new topology has both ZVT and ZCT functions by using two additional components, a switch and a diode. The auxiliary inductor for soft-switching is implemented insi...

A semiconductor solid state switch has been constructed and tested in the prototype extraction kicker pulse generator of CERN's Large Hadron Collider (LHC) [1]. The switch is made of 10 modified 4.5 kV, 66 mm symmetric GTO's (also called FHCT-Fast High Current Thyristor), connected in series. It holds off a d.c. voltage of 30 kV and conducts a 5 μs half-sine wave current of 20 kA with an initia...

SUGAR-SWEETENED SOFT DRINKS CONTRIBUTE 7.1% OF total energy intake and represent the largest single food source of calories in the US diet. Coincidentally or not, the rise of obesity and type 2 diabetes in the United States parallels the increase in sugarsweetened soft drink consumption. Several studies have found an association between sugar-sweetened beverages and incidence of obesity in chil...

The flange climb derailment is one of the cause of derailment for a typical switch. The derailment for the switch is a complex phenomenon since the contact area is changing dynamically. The contact angle between the wheel flange and the switch point is investegated in terms of the risk on the derailment. The contribution of this study is proving that UIC716R standard recommendation about the sw...
