Atmospheric chemistry is a branch of atmospheric science in which the chemistry of the Earth’s atmosphere and that of other planets is studied. Environmental chemistry is the scientific study of the chemical and biochemical phenomena that occur in natural places. It can be defined as the study of the sources‚ reactions‚ transport‚ effects‚ and fates of chemical species in the air‚ soil‚ and water environments; and the effect of human activity on these. Environmental chemistry is an interdisciplinary

What would you do if the phenomenal discovery that you made wasn’t even known as your revelation at all? Unfortunately‚ this happened to me. Despite all of my hard work‚ I was given no credit until recently. I‚ Rosalind Franklin‚ discovered something so fundamental that it has led to a study that could save thousands of lives. To understand how important this is‚ you must know where I started‚ how I made the discovery‚ and what this really all led to. When I was born on July 25‚ 1920

Bellamar Caves are a National Monument that is located in Matanzas‚ Cuba‚ they are a set of cave with more than 23 kilometers of galleries. By the beauty of its gallery and caves‚ they were declared a National Monument. The galleries and passages of the cave started forming about 300 thousand years ago. According to the studies the caves were originally under the sea‚ part of the bat of Matanzas. While they were under sea level‚ these caves were full of water. The tectonic movements caused the area

source oriented medical record (SOR)‚ the information about a patient’s care and illness is organized according to the "source" of the information within the record‚ that is‚ if it is recorded by the physician‚ the nurse‚ or data collected from an xray or laboratory test are filed under their specific sectionalized areas in the chart usually in chronological order. Many facilities use this format since it is easy to locate documents. For example‚ if a physician needs to reference a recent lab report

Firstly the "biomedical model of health" (no hyphen) is sort of open to interpretation and not always defined the same way. And generally speaking a biopsychosocial model is almost universally used. But when I think of a biomedical model is it practicing medicine to "fix" things with the view that medical problems are organic (physical) without considering anything else. Some times it is referred (in an insulting way) to as the biomechanical model. To some extent that is true since a biomedical

detected UHF radio waves. The device proved his theory of the existence of electromagnetic waves. During his research he also found depending on frequency that some waves could be transmitted through some materials and reflected by others‚ as in the xray. His discoveries concerning wavelength and frequency‚ led to many future innovations such as wave based wire telegraphy‚ radio‚ audio‚ and television to come later on. In 1878 Thomas Edison invented an improved version of the incandescent light bulb
