the area of musa bay (khor musa) on which two vital and important ports of imam khomeini (port shapour) and mahshar have taken place on its shore is located geographically at the far northeast of the persian gulf, south of khuzestan province. early in the world war ii, despite iran’s neutral declaration, port shapour was blitzed and occupied by british navy on august 24, 1941. iran's resis...

We developed a flexible port for NOTES which allows the use of conventional forceps for laparoscope-assisted surgery without change. The port is not affected by the location of the through hole in the gastrointestinal tract or vagina which elicits a problem in conventional NOTES, and its length can be adjusted during surgery by cutting the port itself. The port is made of polymer resin with a l...

in coastal areas, hydrodynamic factors make changes in shorelines geomorphology. this can affect coastal facilities and cause hazards to human societies in the areas. this study has investigated the influence of wave and tide properties on khamir port, hormoz strait in coast of persian gulf. the purpose of the study is to make a mathematical regional and local modeling of water level fluctuatio...

significant advantages of intermodal and containerized transport have increased the global interest to this mode of transportation. this growing interest is reflected in the annual volume of container cargo growth. however, the container transport inside iran does not have a proper place. comparing the count of containers entering and leaving ports with the statistics obtained from railway and ...

A digital look-up table adaptive predistortion technique using a six-port receiver for power amplifier linearization is presented. The system is designed in Ka-band for a DVB-S2 satellite link. We use a six-port receiver at the linearizationloop in place of classic heterodyne receivers. The six-port receiver is implemented by the use of passive microwavecircuits and detector diodes. This approa...

Port-wine stain is a vascular malformation characterized pathologically by ectasia of superficial dermal capillaris and clinically by persistent macular erythema. The association of a port-wine stain on a limb with soft tissue swelling, with or without bony overgrowth, is termed klippel-Trenaunay syndrome. Phakomatosis pigmento-vascularis is a combination of port-wine stain and cutaneous ...

BACKGROUND An implantable port device provides an easily accessible central route for long-term chemotherapy. Venous catheter migration is one of the rare complications of venous port implantation. It can lead to side effects such as pain in the neck, shoulder, or ear, venous thrombosis, and even life-threatening neurologic problems. To date, there are few published studies that discuss such co...

The variable displacement pump control system has greater energy-saving advantages and application prospects than the valve control system. However, the variable displacement pump control of differential cylinder is not concurrent with the existing technologies. The asymmetric pump-controlled cylinder is, therefore, used to balance the unequal volume flow through a single rod cylinder in closed...
