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...

This paper presents the effect of inlet port diameter–bore ratios (IPD/B) on effective release energy and internal exhaust residual gas a spark-ignition engine. To investigate in combustion chamber, simulation model is setup based AVL-boost software, to validate an experimental also setup. The results research show that: IPD/B have large energy. When ratio increases from 0.3–0.5, 0.11% 0.14%, 0...

Twisted atrioventricular connections occur almost exclusively in the hearts with biventricular atrioventricular connections. Only one example of double inlet left ventricle has been illustrated in which the axes of the two atrioventricular valves crossed each other. We describe herein three patients, and one autopsied specimen, with double inlet right ventricle in which magnetic resonance imagi...

Organic Rankine Cycle (ORC) is a proven technology in the field of waste heat recovery and present days ORC extensively being used exploiting biomass, geothermal solar energy. The overall performance depends on expander, making it core component system. Generally, these expanders are classified into velocity type displacement type. find their applications large scale power generation not prefer...

The prevalence of heterotopic gastric mucosa of the upper esophagus (inlet patch) has a wide range depending on the method and detail of examination. The inlet patch is believed to be a congenital malformation that rarely leads to symptoms. We aimed to quantify the prevalence of the inlet patch in a non-referred population and determine if there are any risk factors or associated symptoms. Men ...
