this research uses computational modeling to explore another method to increase diesel engine performance while maintaining low pollutant emission levels. previous studies have shown that injection-rate profiles and injector configurations play important roles on the performance and emissions of particulate and nox in di diesel engines. since the most important engine design parameters, includi...

Despite efficient carbon monitoring system and the commercialization of battery technology for intra-port transportation, port management are found not adopting these environmental yet costly equipments. Port authority who regulates environmental policies lacks leverage to impose tangible reduction on emission through concession. This model integrates sustainability into port equipment expansio...

In this data article, we evaluated the daily fluoride contents in 20 household desalinators working by reverse osmosis (RO) process in Bushehr, Iran. The concentration levels of fluoride in inlet and outlet waters were determined by the standard SPADNS method using a spectrophotometer (M501 Single Beam Scanning UV/VIS, UK). The fluoride content in outlet waters were compared with EPA and WHO gu...

implantable ports are used for intravenous infusion therapy and play an important role in management of oncology patients. these ports are best suited for patients requiring long-term therapy (>4 weeks). implanted ports provide reliable venous access protect peripheral access increase patients’ comfort through reducing repeated and difficult vein punctures allow for safe and comfortable adminis...

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...

Background: Laparoscopic Surgery (LS) may be associated with many port site complications such as hernia, bleeding, infection, subcutaneous emphysema and ugly scars. Some of these complications are serious such as obstructed port site hernia . Rate of these complications is low depending  on size and site of the port incision, type of the trocar that it is used, the condition of  the patient a...
