Introduction The natural source of both plasma and electromagnetic radiation (EMR) is the sun. There are various similarities such as the presence of electric and magnetic field in both EMR and plasma. Both transport contain energy and are ubiquitous in the universe. However‚ there are large differences between EMR and plasma. Differences between EMR and plasma EMR is energy that propagates through a medium in the form of EM waves. It has an electric and magnetic field which oscillate in

2. Experiment 2.1. Cold Plasma Jet System This research used a cold atmospheric pressure plasma jet system with an inclined style of treatment (gradient = 45o) as shown in Figure 1. This system was developed based on Teschke et al.32 Medical-grade argon gas (99.999% purity) produced by the Samator Company (Indonesia) was used as a carrier gas. Two aluminium foil ring electrodes were used around the quartz tube for this system. It had a quartz tube with a 1.5 mm inner diameter and a 2.7 mm outer

Bio152 Final Exam Review Essay Questions: Quest 1-2: Describe the fluid mosaic model of plasma membrane structure and list the major components of the membrane. How did scientists discover that the membrane was “fluid”? Explain one experiment that we discussed. • The fluid mosaic model of plasma membrane was the idea that lipids or proteins could move in the membrane laterally. The plasma membrane is made up of a phospholipid bilayer and controls a lot of what goes in and out of the membrane by the

Was America Founded on Christian Principles? Mark Weldon Whitten (1999) refutes that the United States and our fore fathers founded this nation as a Christian nation. Whitten (1999) says there are seven main points that make him believe America was not founded on Christian principles: 1. No prayers or divine guidance or approval‚ were offered during the Constitutional Convention of 1787. 2. The Constitution makes no appeals to religious authorities‚ rationales‚ or purposes. The Constitution

Why is a drug’s plasma half-life important to health care providers? Half life is important in determining the frequency of a drug administered in order to maintain a continuous drug effect. Identify 2 diseases/conditions that can increase the plasma half-life of a drug. It can be prolonged when liver or kidney disease is present. What could happen if a medication with a long half-life continues to be given to a patient with one of the diseases/conditions identified in above? Patients with hepatic

Outline the roles of membrane at the surface of the cell The plasma membrane encloses the cell‚ defines it boundaries and maintains the essential differences between the cytosol and the extra-cellular environment. The separation of the internal and external environment maintains a constant internal environment which is essential for the cell to function efficiently. Membrane receptors can interact with specific molecules corresponding to stimuli such as hormones to generate a signal cascade which

Materials & Methods Brook trout blood was used throughout our experiment as our erythrocyte suspension‚ which consisted of ten drops of fish blood in a test tube containing 10mL of 0.7% NaCl. Eleven other solutions‚ (erythritol‚ xylose‚ monacetin‚ diacetin‚ triacetin‚ urea‚ thiourea‚ glycerol‚ ethylene glycol‚ glucose and fructose) all isosmotic but not necessarily isotonic with the cytoplasm of the erythrocyte‚ were combined with a 0.2mL of well-mixed stock suspension were added to 0.27M of each
