Washington State: an embarrassment to college football (again)

whatshouldicareabout

Yeah, there could be a hundred things I could put here to make that title true, but since the topic of scheduling is hot, here's Wazzu's TUFF and AWESOME non-con schedules from 2014-2018. Try not to vomit in your mouth

http://www.fbschedules.com/2014/05/washington-state-non-conference-football-schedule-2018/

Someone should tell Woody that if he tries this bullshit, he'll be ASS.DOOR.OUT.

PostGameOrangeSlices

Lots of Palouse championship games against idaho and boise.

What cool offseasons to be a potato farmer, man

Disagree. Those schedules aren't C, C, F schedules at all. They are barely a C, F, F schedule.

I mean this could very well be an all F schedule.

09/01 – at Wyoming
09/08 – San Jose State
09/15 – Eastern Washington

I'll give Wyoming a D since it's on the road but still. Also you know your football program sucks donkey balls when you have to give Wyoming a fucking return trip.

Sidenote: Why the hell are NW schools playing SUNJ so much? Do they think NE recruits will come 3,000 miles west? Is UConn next or something?

Schedules are pathetic now. It's time to stop watching the games in person or on TV. Don't even take free tickets from work or friends, at least not to OOC shit games.

Altitude
From Wikipedia, the free encyclopedia
For other uses, see Altitude (disambiguation).
Not to be confused with Attitude.

Altitude or height is defined based on the context in which it is used (aviation, geometry, geographical survey, sport, and more). As a general definition, altitude is a distance measurement, usually in the vertical or "up" direction, between a reference datum and a point or object. The reference datum also often varies according to the context. Although the term altitude is commonly used to mean the height above sea level of a location, in geography the term elevation is often preferred for this usage.

Vertical distance measurements in the "down" direction are commonly referred to as depth.

Altitude in aviation and in spaceflight
Vertical Distance Comparison

In aviation, the term altitude can have several meanings, and is always qualified by either explicitly adding a modifier (e.g. "true altitude"), or implicitly through the context of the communication. Parties exchanging altitude information must be clear which definition is being used.[1]

Aviation altitude is measured using either Mean Sea Level (MSL) or local ground level (Above Ground Level, or AGL) as the reference datum.

Pressure altitude divided by 100 feet (30m) as the flight level, and is used above the transition altitude (18,000 feet (5,500 m) in the US, but may be as low as 3,000 feet (910 m) in other jurisdictions); so when the altimeter reads 18,000 ft on the standard pressure setting the aircraft is said to be at "Flight level 180". When flying at a Flight Level, the altimeter is always set to standard pressure (29.92 inHg / 1013.25 mbar).

On the flight deck, the definitive instrument for measuring altitude is the pressure altimeter, which is an aneroid barometer with a front face indicating distance (feet or metres) instead of atmospheric pressure.

There are several types of aviation altitude:

Indicated altitude is the reading on the altimeter when the altimeter is set to the local barometric pressure at Mean Sea Level.
Absolute altitude is the height of the aircraft above the terrain over which it is flying. Also referred to feet/metres above ground level (AGL).
True altitude is the actual elevation above mean sea level. It is Indicated Altitude corrected for non-standard temperature and pressure. In UK aviation radiotelephony usage, the vertical distance of a level, a point or an object considered as a point, measured from mean sea level; this is referred to over the radio as altitude.(see QNH)[2]
Height is the elevation above a ground reference point, commonly the terrain elevation. In UK aviation radiotelephony usage, the vertical distance of a level, a point or an object considered as a point, measured from a specified datum; this is referred to over the radio as height, where the specified datum is the airfield elevation (see QFE)[2]
Pressure altitude is the elevation above a standard datum air-pressure plane (typically, 1013.25 millibars or 29.92" Hg). Pressure altitude and indicated altitude are the same when the altimeter is set to 29.92" Hg or 1013.25 millibars.
Density altitude is the altitude corrected for non-ISA International Standard Atmosphere atmospheric conditions. Aircraft performance depends on density altitude, which is affected by barometric pressure, humidity and temperature. On a very hot day, density altitude at an airport (especially one at a high elevation) may be so high as to preclude takeoff, particularly for helicopters or a heavily loaded aircraft.

These types of altitude can be explained more simply as various ways of measuring the altitude:

Indicated altitude – the altimeter reading
Absolute altitude – altitude in terms of the distance above the ground directly below
True altitude – altitude in terms of elevation above sea level
Height – altitude in terms of the distance above a certain point
Pressure altitude – the air pressure in terms of altitude in the International Standard Atmosphere
Density altitude – the density of the air in terms of altitude in the International Standard Atmosphere

Altitude regions

The Earth's atmosphere is divided into several altitude regions:[3]

Troposphere — surface to 8,000 metres (5.0 mi) at the poles – 18,000 metres (11 mi) at the equator, ending at the Tropopause.
Stratosphere — Troposphere to 50 kilometres (31 mi)
Mesosphere — Stratosphere to 85 kilometres (53 mi)
Thermosphere — Mesosphere to 675 kilometres (419 mi)
Exosphere — Thermosphere to 10,000 kilometres (6,200 mi)

High altitude and low air pressure

Regions on the Earth's surface (or in its atmosphere) that are high above mean sea level are referred to as high altitude. High altitude is sometimes defined to begin at 2,400 metres (8,000 ft) above sea level.[4][5][6]

At high altitude, atmospheric pressure is lower than that at sea level. This is due to two competing physical effects: gravity, which causes the air to be as close as possible to the ground; and the heat content of the air, which causes the molecules to bounce off each other and expand.[7]

Because of the lower pressure, the air expands as it rises, which causes it to cool.[8][9] Thus, high altitude air is cold, which causes a characteristic alpine climate. This climate dramatically affects the ecology at high altitude.
Relation between temperature and altitude in Earth's atmosphere
Main article: Lapse rate

The environmental lapse rate (ELR), is the rate of decrease of temperature with altitude in the stationary atmosphere at a given time and location. As an average, the International Civil Aviation Organization (ICAO) defines an international standard atmosphere (ISA) with a temperature lapse rate of 6.49 K(°C)/1,000 m (3.56 °F or 1.98 K(°C)/1,000 Ft) from sea level to 11 kilometres (36,000 ft). From 11 to 20 kilometres (36,000 to 66,000 ft), the constant temperature is −56.5 °C (−69.7 °F), which is the lowest assumed temperature in the ISA. The standard atmosphere contains no moisture. Unlike the idealized ISA, the temperature of the actual atmosphere does not always fall at a uniform rate with height. For example, there can be an inversion layer in which the temperature increases with height.
Effects of high altitude on humans
Main article: Effects of high altitude on humans

Medicine recognizes that altitudes above 1,500 metres (4,900 ft) start to affect humans,[10] and there is no record of humans living at extreme altitudes above 5,500–6,000 metres (18,000–19,700 ft) for more than two years.[11] As the altitude increases, atmospheric pressure decreases, which affects humans by reducing the partial pressure of oxygen.[12] The lack of oxygen above 2,400 metres (8,000 ft) can cause serious illnesses such as altitude sickness, high altitude pulmonary edema, and high altitude cerebral edema.[6] The higher the altitude, the more likely are serious effects.[6] The human body can adapt to high altitude by breathing faster, having a higher heart rate, and adjusting its blood chemistry.[13][14] It can take days or weeks to adapt to high altitude. However, above 8,000 metres (26,000 ft), (in the "death zone"), altitude acclimatization becomes impossible.[15]

There is a significantly lower overall mortality rate for permanent residents at higher altitudes.[16] Additionally, there is a dose response relationship between increasing elevation and decreasing obesity prevalence in the United States.[17] In addition, the recent hypothesis suggests that high altitude could be protective against Alzheimer's disease via action of erythropoietin, a hormone released by kindney in response to hypoxia.[18] However, people living at higher elevations have a statistically significant higher rate of suicide.[19] The cause for the increased suicide risk is unknown so far.[19]
Athletes

For athletes, high altitude produces two contradictory effects on performance. For explosive events (sprints up to 400 metres, long jump, triple jump) the reduction in atmospheric pressure signifies less atmospheric resistance, which generally results in improved athletic performance.[20] For endurance events (races of 5,000 metres or more) the predominant effect is the reduction in oxygen which generally reduces the athlete's performance at high altitude. Sports organizations acknowledge the effects of altitude on performance: the International Association of Athletic Federations (IAAF), for example, marks record performances achieved at an altitude greater than 1,000 metres (3,300 ft) with the letter "A".[21]

Athletes also can take advantage of altitude acclimatization to increase their performance. The same changes that help the body cope with high altitude increase performance back at sea level.[22][23] These changes are the basis of altitude training which forms an integral part of the training of athletes in a number of endurance sports including track and field, distance running, triathlon, cycling and swimming.
Effect of altitude on animals

Decreased oxygen availability and decreased temperature make life at high altitude challenging. Despite these environmental conditions, many species have been successfully adapted at high altitudes. Animals have developed physiological adaptations to enhance oxygen uptake and delivery to tissues which can be used to sustain metabolism. The strategies used by animals to adapt to high altitude depend on their morphology and phylogeny.
Fish

Fish at high altitudes may also have a lower metabolic rate, as has been shown in highland westslope cutthroat trout compared to introduced lowland rainbow trout in the Oldman River basin.[24] There is also a general trend of smaller body sizes and lower species richness at high altitudes observed in aquatic invertebrates, likely due to lower oxygen partial pressures.[25][26][27] These factors may decrease productivity in high altitude habitats, meaning there will be less energy available for consumption, growth, and activity, which provides an advantage to fish with lower metabolic demands.[24]

The naked carp from Lake Qinghai, like other members of the carp family, can use gill remodelling to increase oxygen uptake in hypoxia.[28] The response of naked carp to cold and low-oxygen conditions seem to be at least partly mediated by hypoxia-inducible factor 1 (HIF-1).[29] It is unclear whether this is a common characteristic in other high altitude dwelling fish or if gill remodelling and HIF-1 use for cold adaptation are limited to carp.
Rodents

Rodents living at high altitude include deer mice, guinea pigs and rats. As small mammals they face the challenge of maintaining body heat in cold temperatures, due to their large volume to surface area ratio. As oxygen is used as a source of metabolic heat production, the hypobaric hypoxia at high altitudes is problematic.

There are a number of mechanisms that help them survive these harsh conditions including altered genetics of the hemoglobin gene in guinea pigs and deer mice.[30][31] Deer mice use a high percentage of fats as metabolic fuel at high altitude to retain carbohydrates for small burst of energy.[32] To convert fats to energy in the form of ATP, more oxygen is required than to convert the same amount of carbohydrates. The reason they use fats is believed to be because they have it in large stores, but also means that they must eat more or they will begin to lose weight.

Other physiological changes that occur in rodents at high altitude include increased breathing rate[33] and altered morphology of the lungs and heart allowing more efficient gas exchange and delivery. Lungs of high altitude mice are larger, with more capillaries,[34] and hearts of mice and rats at high altitude have a heavier right ventricle,[35][36] which pumps blood to the lungs.

At high altitudes, some rodents even shift their thermal neutral zone so they may maintain normal basal metabolic rate at colder temperatures.[37]
Birds

Birds have been especially successful at living at high altitudes.[38] In general, birds have physiological features that are advantageous for high-altitude flight. The respiratory system of birds moves oxygen across the pulmonary surface during both inhalation and exhalation, making it more efficient than that of mammals.[39] In addition, the air circulates in one direction through the parabronchioles in the lungs. Parabronchioles are oriented perpendicular to the pulmonary arteries, forming a cross-current gas exchanger. This arrangement allows for more oxygen to be extracted compared to mammalian concurrent gas exchange; as oxygen diffuses down its concentration gradient and the air gradually becomes more deoxygenated, the pulmonary arteries are still able to extract oxygen.[40] Birds also have a high capacity for oxygen delivery to the tissues because they have larger hearts and cardiac stroke volume (mL / min) compared to mammals of similar body size.[41] Additionally, they have an increased vascularization in flight muscle due to increased branching of capillaries and small muscle fibres (which increases surface-area-to-volume ratio).[42] These two features facilitate oxygen diffusion from the blood to muscle, allowing flight to be sustained during environmental hypoxia. Bird's hearts and brains, which are very sensitive to arterial hypoxia, are more vascularized compared to mammals.[43] The bar-headed goose (Anser indicus) is an iconic high flyer that surmounts the Himalayas during migration,[44] and serves as a model system for derived physiological adaptations for high-altitude flight.
