The EGR system routes a number of the exhaust gases (6 ? 10%) from the EGR valve, last on the Intake System, and ultimately within the combustion chamber. The exhaust gases are inert i.e. they cannot burn in the combustion chamber; also, the exhaust gases take up a number of the space which would preferably be taken with the intake air. This reduces the volume of intake air readily available for the combustion process during each Power Stroke; which in turn decreases the peak combustion temperatures. This brings about lower NOx emissions. '10 February. The Peregrine flew north across the valley. He was half miles away, but I could see the brown and black of his wings, the shining gold of his back. The pale cream of his tail coverts looked like a band of straw twisted across the base of his tail. Thinking he'd return downwind, I went into fields with the river to watch for him. I stood in the lee of the hawthorn hedge, looking through it on the north, sheltered in the bitter wind' A digital personal health record (PHR) can be a computer-based software that lets you store a variety of personal health information including illnesses, hospitalizations, encounters (i.e. visits and communications), journal information in between doctor visits, medications, allergies, immunizations, surgeries, lab results, and ancestors and family history. The personal health record differs from an electronic digital medical record which can be a similar application with considerably more all-encompassing features used by healthcare providers for example scheduling and insurance billing, besides the storage of patient health data. Owning and looking after an up-to-date digital personal health record has several benefits and is the cornerstone of proactive healthcare involvement and better healthcare experiences.
