| Microelectronic Pill | | | | | | 1.INTRODUCTION The invention of the transistor enabled the first radio telemetry capsules‚ which utilized simple circuits for in vivo telemetric studies of the gastro-intestinal tract. These units could only transmit from a single sensor channel‚ and were difficult to assemble due to the use of discrete components. The measurement parameters consisted of temperature‚ pH or pressure‚ and the first attempts of conducting real-time noninvasive

in the heart. • ECG waveforms are produced by the movement of charged ions across the semipermeable membranes of myocardial cells. • There are 12 recording leads in the standard ECG. Changes in a 12-lead ECG may occur with ischemia‚ infarction‚ electrolyte imbalance‚ conduction disturbances‚ dysrhythmias‚ or drug toxicity. • Continuous ECG monitoring is done using one or more leads and based on the patient’s clinical status. • Telemetry monitoring involves the observation of a patient’s heart rate

November 2014 Tej Kulkarni Types of Corrosion and Their Effects on Aircraft Structural Integrity Introduction Today the vast majority of aircraft are made out of various types of metal. All metals are susceptible to corrosion which is why from the moment that any metallic aircraft component is manufactured it is treated to prevent corrosion. Certain elements are often added to base metals by manufacturers in order to create corrosion resistant alloys and metallic components are normally

the past three years and have been trained in identifying the various rhythms that the heart can have. In my training‚ I have learned that there are chemical reasons why the heart will behave in certain ways. The body needs to have a balance of electrolytes (substances that can conduct electricity) to function properly. This is especially important in the heart. Sodium is needed for the generation of electrical signals vital for movement. The heartbeat is generated through electrical impulses that

The statue of Liberty first arrived in America in 1886 and took up permanent residency on Bedloe’s island in New York Harbor. The statue weighs in at 280 tons and is visible for more than 42 miles on a clear day. The statue of Liberty is without a doubt‚ among the most monumental figures in American history. The Statue of Liberty is made of an aluminum scaffolding‚ an iron framework and metal skin made from copper. Originally‚ she was to be made of bronze‚ but weight problems required a switch to

CaCO3+H2SO4 CaSO4+ H20+CO2. In general terms‚ this is the simplest form of what’s going on in a metathesis reaction: AX + BY AY + BX. A metathesis reaction will result in one or more of the following: formation of a precipitate‚ weak or non- electrolyte‚ and/or gas. Metathesis reactions are one of the three chemical reactions possible in an aqueous solution. Chemical reactions are the transforming of any chemicals from one state of chemicals (gas‚ liquid‚ or solid) into another state. There are

back to the heart to receive more oxygen in the lungs. Blood is also part of the cardiovascular system. Blood is the fluid that transports the disease-fighting white blood cells‚ the oxygen-supplying red blood cells‚ and the fuel-replenishing electrolytes to the body’s various tissues. There are two systems for circulating blood. During pulmonary circulation‚ the deoxygenated blood that has been returned to the heart is pumped into the lungs‚ where it receives more oxygen‚ and then pumped back into

Clinical features and diagnosis of diabetic ketoacidosis in children INTRODUCTION — Diabetic ketoacidosis (DKA) is the leading cause of morbidity and mortality in children with type 1 diabetes mellitus. DKA can less commonly occur in children with type 2 diabetes mellitus [1‚2]. (See "Classification of diabetes mellitus and genetic diabetic syndromes".) In recent years‚ the incidence and prevalence of type 2 diabetes mellitus have increased across all ethnic groups. This has been coupled with an

However‚ the myth that bed rest is good for you when ill or recuperating still persists in our world. An abundance of scientific research in the past 50 years demonstrates the specific damage done to each of the body’s
