gravity and orthostatic changes‚ but first‚ what is blood pressure and why is it important? Blood pressure is the force exerted by blood against a unit area of the blood vessel walls (Marieb‚ Hoehn 2013)‚ and is measured in millimeters of mercury (mm Hg) with two different pressures‚ the systolic‚ which is the number on top‚ and the diastolic‚ the number on the bottom. The systolic pressure represents the amount of force being excreted during the peak of ventricular contraction‚ also the time when

The headwaters of the Doce River rise in the southeast-east area (SE-E) of the Iron Quadrangle‚ located in south-central portion (C-S) of the state of Minas Gerais (Figure 1). The Iron Quadrangle is historically known as a rich auri-ferriferous province and is a classic region of the world Precambrian geology (Dorr‚ 1959). Its designation results from the area’s planimetric features‚ with a surface area of around 7‚000 km2‚ comprising the most important iron mines of Minas Gerais (Barbosa‚ 1968)

however‚ science to an efficient mercury capture. Jacob described this as the 3 Cs- the Contact of mercury (which is in very dilute concentrations in the flue gas) with the capture media; Conversion of elemental mercury (Hg0) to an oxidized state (Hg+ or Hg++) to enhance the mercury’s receptivity to the capture media‚ and Capture of the mercury in the capture media’s structure. The 3Cs are an exact science and must occur in seconds to work. Activated carbon is basically a giant butterfly net to catch

in your vessels when your heart rests between beats ("High Blood Pressure"‚ 2010). A healthy blood pressure reading is lower than 120/80mmHg and pre-hypertension is between 120/80mm Hg and 139/89mmHg. Stage one hypertension is between 140/90mm Hg and 159/99mm Hg and stage two hypertension is a reading of 160/100mm Hg or higher ("About High Blood Pressure"‚ 2012). High blood pressure raises your risk for heart disease and stroke and is one of leading causes of death in the United States. It is often
