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 ...

Effect of traditional fermentation on pH, titratable acidity, proteins, amino acids, and sugars contents three local sorghum cultivars namely Hamra, Biadah Shahla used in making khamir bread were investigated. During 24 fermentations, the pH fermented dough dropped sharply this was coincided with increase total acidity. Fermentation found to cause no significant change protein content cultivars...

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...

BACKGROUND The purpose of the current study was to evaluate whether a totally implanted valved subcutaneous port system would have fewer complications as compared to a standard nonvalved port. METHODS Study subjects requiring port placement were randomized to receive a valved port (PASV; Boston Scientific, Natick, MA) or a nonvalved port (BardPort; Bard Accesss Systems, Salt Lake City, UT). E...

This paper studies the comparison of two kinds of port regulation modes – the centralization mode and the decentralization mode – using principal-agent theory and dynamic game theory. The optimal tariffs, port capacities and port efficiency levels under these two regulation modes are determined. The theoretical results are applied to the container terminals in Port of Shanghai in China. Sensiti...
