The value of the pK a changes with temperature and can be understood qualitatively based on Le Châtelier's principle: when the reaction is endothermic, K a increases and pK a decreases with increasing temperature; the opposite is true for exothermic reactions. The value of pK a also depends on
Body mass index (BMI) is a value derived from the mass and height of a person. The BMI is defined as the body mass divided by the square of the body height, and is expressed in units of kg/m 2, resulting from mass in kilograms (kg) and height in metres (m).

So that practical clothing may be described conveniently by a range of small integers, the unit of thermal resistance, to be called the “tog,” is the resistance that will maintain a temperature difference of 0-1°C. with a flux of 1 watt per square metre, or in more practical terms, 10°C. with a flux of 1 watt per square decimetre.
A normal bladder can hold up to 16 ounces (half a liter) for 3–5 hours comfortably. Numerous diseases affect the urinary system including kidney stones , which are formed when materials in the urine concentrate enough to form a solid mass, urinary tract infections , which are infections of the urinary tract and can cause pain when urinating ...
Modalities applied to measurement of ejection fraction is an emerging field of medical mathematics and subsequent computational applications. The first common measurement method is echocardiography, [7] [8] although cardiac magnetic resonance imaging (MRI), [8] [9] cardiac computed tomography, [8] [9] ventriculography and nuclear medicine (gated SPECT and radionuclide angiography) [8] [10 ...
Mean kinetic temperature (MKT) is a simplified way of expressing the overall effect of temperature fluctuations during storage or transit of perishable goods. The MKT is used to predict the overall effect of temperature fluctuations on perishable goods. It has more recently been applied to the pharmaceutical industry.
With a normal P a O 2 of 60–100 mmHg and an oxygen content of F I O 2 of 0.21 of room air, a normal P a O 2 /F I O 2 ratio ranges between 300 and 500 mmHg. A P a O 2 / F I O 2 ratio less than or equal to 200 mmHg is necessary for the diagnosis of acute respiratory distress syndrome by the AECC criteria . [ 7 ]
