Peak Flow Meter A peak flow meter is a device that helps you determine how well your asthma is being controlled and how well your lungs are working at a given time. This is a simple but important tool in daily asthma management. Peak flow meters are available over the counter. The readings from the meter will help you and your health care provider: • Determine the severity of your asthma. • Evaluate the effectiveness of your current treatment. • Determine when to add or stop certain
2.7.1 What is a peak flow meter A Peak flow meter is a medical device that measures how well your lungs are able to expel air [2.1]. By blowing rough a mouthpiece a peak expiatory flow (PEF) reading can be found. This reading is measured in litres per minute and can be read directly from the device. When the person’s airways are more closed the lower the rate in which air can be blown out. The peak flow meters are used as a simple and efficient way of monitoring how well your lungs are and see if
rough cross section, big boulders and turbulent flow. An electrical conductivity (EC) meter was used for discharge measurement. Salt dilution method is particularly used for measurement of flow in mountainous stream and any other sites where high degree of turbulence exists to ensure complete mixing of injected solution in the pre-determined length of the channel. Under such condition of flow, the conventional approach to flow gauging such as current meter or calibrated structure are not feasible. NaCl
of a prolonged attack (Grossman, 2014). Diagnosis of asthma is comprised of a focused history, physical examination, and diagnostics such as laboratory testing, chest x-ray, and pulmonary function testing. According to Grossman (2014), the peak expiratory flow (PEF) can help to determine the level of asthma exacerbation. Treatment is typically based on the severity and can consist of pharmacological as well as non-pharmacological
another process that estimates the narrowing of bronchial tubes by checking how much air an individual can exhale after a deep breath and how fast the patient breathes out. Peak flow meters are a common test procedure for asthma.1 The peak flow meter is a device that measures how hard you breathe out or exhale. Lower readings on the meter shows a diminished lung capacity resulting in less effective breathing. It is generally a strong signal that an individual's asthma may be getting worse.2 These measurements
Volcanos: Mount Rainier Mount Rainier is a volcano that is located in the Cascade Range in Mount Rainier National Park, Washington. This volcano is 14,411 feet (4,392 meters) in its elevation. This is the highest mountain in Washington. This volcano is in the same mountain range as Mount Adams, Mount Baker, Mount St. Helens and Glacier Peak. It is known as a stratovolcano which is a large, steep volcano built up of alternating layers of lava and ash or cinders. This volcano is an active volcano and the
filters incorporating an alkaline medium are used to increase the pH value of acidic water. Rapid gravity sand filters usually consist of rectangular tanks containing silica sand (size range 0.5 to 1.0 mm) to a depth of between 0.6 and 1.0 m. The water flows downwards and solids become concentrated in the upper layers of the bed. Treated water is collected via nozzles in the floor of the filter. The accumulated solids are removed periodically by backwashing with treated water, usually preceded by scouring
The Netherlands vs. Deerania The Kingdom of the Netherlands and Deerania have many similarities as well as differences between each other. For instance, Deerania is a lot bigger, but they are both quite dense-although The Netherlands is even denser because of its small size compared to its large population. Since the Netherlands is so dense, there are even three times as many bikes as there is as cars (to keep road traffic down)! They also use boats to get to work and travel. Deerania also uses
Why Mt. Lassen is what it is today Lassen Peak, also known as Mount Lassen, is the southernmost active volcano in the Cascade Range. It is part of the Cascade Volcanic Arc which is an arc that covers southwestern British Columbia to northern California. Located in the Shasta Cascade region of Northern California, Lassen rises 2,000 meters above the surrounding terrain and has a volume of 0.5 cubic miles, making it one of the largest lava domes on Earth. It was created on the destroyed northeastern

Tabo Monestery The ancient village of Tabo situated on the left bank of the river Spiti, is about 163 km from Kalpa or 47 Kms from Kaza. Located at an altitude of 3050 meters above sea level, the village has one of the most important cave Buddhist monastery, next only to the Tholing Gompa in Tibet. The largest monastic complex in the valley and one of the oldest functioning Buddhist monastery, it has been declared a protected
highest population density in the world with 847 inhabitants per square kilometer. Bangladesh is one of the world's least developed countries and prone to natural disasters, such as cyclones, floods and droughts. Half of it is less than five meters above sea level. Therefore any change in the earth’s temperature that causes the level of the oceans to rise would seriously affect the flooding of the delta area of Bangladesh. A fifth to a third of the country is annually flooded by the river
1-Introduction: For the last 40 years, Riyadh, the capital city of Saudi Arabia, has developed from a modest town into a metropolis with a population of around 8 million people today. The increased economic activity, as well as the increase in traffic and yet traffic congestion in the modern road networks due to the growing number of cars have generated additional delays and less road safety. Can anyone imagine that drivers spend a lot of time behind their wheels in Riyadh? Traffic jams are causing
Ethiopia is located in the Eastern region of Africa. According to the Embassy of Federal Democratic Republic of Ethiopia, Ethiopia lies between the geographical coordinates of 3’ and 14. 8’ latitude and 33’and 48’ longitude. Ethiopia encompasses a majority of the area known as the Horn of Africa. The CIA World Factbook states that Ethiopia is approximately 1,104,300 square kilometers (686,180 miles). To give a better perspective of the sheer size of this country, it is about twice the size of the

Flooding has plagued the Yangtze for centuries; Chinese authorities estimate that some 300,000 people were killed in the 20th century's largest Yangtze River floods. In 2012 during the peak flood season, with a peak flow of 70,000 cubic meters of water per second (Angela), the TGD performed as expected controlling the floodwaters, from flooding the Yangtze saving thousands of lives. Production of power has been as inclusive as preventing flooding, “the hydropower
1. Introduction Obesity is a label given to individuals who have a body mass index (BMI) of above 30. Any individual male or female is considered to be morbidly obese if the BMI was above 40 (NHS, 2012). Being obese for a period of time can increase the risk of obesity related diseases including diabetes, heart disease and certain types of cancers (colon cancer, bowel or breast cancer) and even a greater risk of strokes (NHS, 2012). The World Health Organisation (Who) (2013) states that obesity

Over the years my family has taken numerous road trips across the country. During these trips we would pass through countless wind farms which would peak my curiosity. Therefore, I decided to do some research into wind turbines. A wind turbine is a device that converts kinetic energy from the wind into mechanical energy. If the mechanical energy is used to produce electricity, the device may be called a wind generator, wind charger or wind turbine. If the mechanical energy is used to drive machinery
also has effects the resistivity of the conducting surface. Resistivity is a "bulk property of material describing how well that material inhibits current flow. This is slightly different from resistance, which is not a physical property. If one considers current flowing through a unit cube of material (say, a solid metal cube that measures 1 meter on each side), resistivity is defined as the voltage measured across the unit cube length (V/m) divided by the current flowing through the unit cube's cross
to power. To do this, solar cells are made with a material called a semiconductor, which, for solar cells is almost always silicon. When light hits this material, it causes electrons to break loose and flow throughout the material. By placing metal plates on the solar cell, we can capture this flow of electrons, otherwise known as current. Using the equation Power= Volts * Current, you can calculate the voltage output of a cell, which, using silicon, is about 1.1 volts- a 25% or so efficiency. There
