Essentially, APNs are registered nurses with advanced education in regard to a specific role as well as patient population, particularly prepared at the Masters level (Mancuso & Udlis, 2012). As such, APNs are usually prepared through training as well as certification mainly to assess, order tests, diagnose, prescribe medications and manage patients with various health problems. In the United States, APNs are categorized into four categories based on their preparation and specific role, these categories include; nurse practitioners, clinical nurse specialists, certified nurse-midwives ...

Brightlight is constructing a boutique hotel with 200 guest rooms, and a lighting system that would best suit the rooms has to be decided. Given a choice between conventional incandescent bulbs and compact fluorescent bulbs (CFLs), CFLs are the best option as they have longer lives, consume less energy and are cost effective.

Incandescent bulbs contain a tungsten filament which, when heated to high temperature glows and emits light. But, most of the electricity is wasted as heat and only a part is converted into light. Whereas in CFLs, vaporized mercury emits ultraviolet radiation, this in turn excites fluorescent phosphor coating in the bulb ...

Industries produce things and commodities. The increase in population has also increased the number of industries in the world. It means the industrialization is taking place with a rapid speed. But this industrialization has put forward the matter of pollution to the environment. These industries when working they emit various harmful gases. Along with these gases there are many wastes that are also thrown out of the industries. This waste is usually called in many articles and journals as “by humans for humans”. But the industrial waste is not actually for humans only but is dangerous and hazardous for sea ...

- What causes climate change? Define the Greenhouse Effect

Greenhouse gases (GHG) allow sunlight to enter the atmosphere and absorbs the heat produced by that light. Most of this heat energy is trapped within the atmosphere by the GHG while some of them are let out into the space. The phenomenon of atmospheric heating due to the GHG is called as the greenhouse effect. Gases such as carbon dioxide, methane, nitrous oxide and fluorinated gases form the greenhouse gases. Burning of fossil fuels, manufacturing processes, decay of organic matter, agricultural industries and emission of synthetic fluorinated gases from various ...

Carbon Footprint

Introduction The number of private vehicles are now increasing. It is an alarming issue since more cars mean more sources of greenhouse gas emissions. These vehicles used traditional diesel and gasoline engines which emits large amounts of greenhouse gases (Barmore, 2013). The current number of cars reached about 1 billion. The largest quantity of cars is from the United States which is the birthplace of the land vehicles. The latest trend about the quantity of private vehicles is that it will be doubled in 2030. That is about 2 billion cars that are contributing to the air pollution ...

What is sunlight?

The sun provides tirelessly every square meter of the earth's surface, which it attacks, with an average of about 1370 watts of power (in the form of electromagnetic radiation). We say that the sun burns, but actually it does not. Instead, the sun is a giant nuclear reactor (Layton & Freudenrich, 2000). This solar energy is called the solar constant, since it does not change, except for minor fluctuations. Solar energy is sent in the form of light waves. Light is an electromagnetic wave. The frequency of light - or how fast the waves vibrate - determines the differences in color. ...
