The SA (sinoatrial node) is a pacemaker that is in the right atrium of the heart. SA node control the heart rate using the electrical impulses that sends to the heart muscles and this is how the heart pumping blood out to the entire body and how the heart contract. The stages of the pathway of action potential: 1) The Action Potential is in the Sinoatrial node (SA). Action potential then travels from the SA node to the AV (atrioventricular node) by crossing to the wall of the atrium. 2) Then the

Design technique of P-type CMOS circuit for gate-leakage Reduction in deep submicron Aneesha R1‚ Shabnoor Naaz M2 8th Semester‚ E&C Dept‚ BIT Mangalore 1anee.star@ymail.com 2naazshaik.44@gmail.com Abstract— Before the CMOS process is scaled into deep sub-micron process‚ dynamic energy loss has always dominated power dissipation‚ while leakage power is little. The aggressive scaling of device dimensions and threshold voltage has significantly increased leakage current exponentially‚ thus the

Activity 1 Pre-Lab Quiz K+ inside a cell = 150 mM; K+ outside a cell = 5 mM Na+ inside a cell = 5 mM; Na+ outside a cell = 150 mM Stop & Think question What is the polarity of the resting membrane potential (voltage)? Negative What does it mean that the voltage just inside the membrane is negative? B Membrane of most cells contains K+ leak channels…..b What will happen to the resting membrane potential if the extracellular K+ concentration is increase? Less negative What happens

Gravitation Gravitational field strength at a point is defined as the gravitational force per unit mass at that point. Newton’s law of gravitation: The (mutual) gravitational force F between two point masses M and m separated by a distance r is given by F = | GMm | (where G: Universal gravitational constant) | | r2 | | or‚ the gravitational force of between two point masses is proportional to the product of their masses & inversely proportional to the square of their separation. Gravitational

pH In chemistry‚ pH is a measure of the acidity or basicity of an aqueous solution. Solutions with a pH less than 7 are said to be acidic and solutions with a pH greater than 7 are basic or alkaline. Pure water has a pH very close to 7. pH is defined as the decimal logarithm of the reciprocal of the hydrogen ion activity‚ aH+‚ in a solution. Universal indicator consists of a mixture of indicators such that there is a continuous color change from about pH 2 to pH 10. Universal indicator paper
