About 45 percent of the loss in growth was attributable to disease, 20 percent to insects, 17 percent to fire, and 18 percent to weather, animals, and various other causes.

This serious condition, popularly known as pyorrhea, is one of the chief causes of tooth loss in adults.

It has been claimed by one study that abiotic stress causes the most crop loss of any other factor and that most major crops are reduced in their yield by more than 50 % from their potential yield.

Excessive erosion causes problems such as desertification, decreases in agricultural productivity due to land degradation, sedimentation of waterways, and ecological collapse due to loss of the nutrient rich upper soil layers.

The loss of kinetic energy via reacting electrons causes light to be released.

Other common causes of low hemoglobin include loss of blood, nutritional deficiency, bone marrow problems, chemotherapy, kidney failure, or abnormal hemoglobin ( such as that of sickle-cell disease ).

Risk is the likelihood that something bad will happen that causes harm to an informational asset ( or the loss of the asset ).

Any factor that causes a greater likelihood of loss should theoretically be charged a higher rate.

An important caveat about lossy compression is that ( formally, transcoding ) or editing lossily compressed files causes digital generation loss from the re-encoding.

The more tightly bound the nucleus, the more energy is lost during formation and this binding energy loss causes the elemental masses not to be related through simple fractions.

Schizophrenia causes a total loss of 16. 8 million DALY, and bipolar disorder 14. 4 million.

Efundja, the annual flooding of the northern parts of the country, often causes not only damage to infrastructure but loss of life.

In an October 2010 report titled Saving Our Vanishing Heritage, Global Heritage Fund named Nineveh one of 12 sites most " on the verge " of irreparable destruction and loss, citing insufficient management, development pressures and looting as primary causes.

Collapse ( transient loss of postural tone with or without loss of consciousness ) leads to a significant risk of falls ; causes of syncope are manifold, but may include cardiac arrhythmias ( irregular heart beat ), vasovagal syncope, orthostatic hypotension ( abnormal drop in blood pressure on standing up ), and seizures.

* In general, immobilization causes bone loss ( following the ' use it or lose it ' rule ).

Inflammation of the optic nerve causes loss of vision usually because of the swelling and destruction of the myelin sheath covering the optic nerve.

The extinction of the Passenger Pigeon has two major causes: commercial exploitation of pigeon meat on a massive scale and loss of habitat.

This often causes a loss of function in the protein, as critical parts of the amino acid chain are no longer created.

The aging process results in evaporation, so each year in the cask causes a loss of volume as well as a reduction in alcohol.

In packet switched systems where the load and the throughput always are equal ( where packet loss does not occur ), the maximum throughput may be defined as the minimum load in bit / s that causes the delivery time ( the latency ) to become unstable and increase towards infinity.

** An American Airlines Boeing 707 crashes on takeoff at New York International Airport, after a rudder malfunction causes an uncontrolled roll, resulting in the loss of control of the aircraft, with the loss of all life on board.

Although the cause of the decline is not fully understood, habitat loss and conflicts with humans are currently the greatest causes of concern.

It occurs in a hypotonic environment, where water moves into the cell by osmosis and causes its volume to increase to the point where the volume exceeds the membrane's capacity and the cell bursts.

In 2010, Currie, though still favouring the hunting pack hypothesis, admitted that the concentration could have been brought about by other causes, such as a slowly rising water level during an extended flood.

Earthquakes he asserted were the result either of lack of moisture, which causes the earth to break apart because of how parched it is, or of overabundance thereof, which also causes cracks in the earth because of the excess of water.

The increasing eastward momentum imparted by the winds causes water parcels to drift outwards from the axis of the Earth's rotation ( in other words, northward ) as a result of the Coriolis force.

In other words, it is not the relative motion of the pail and water that causes concavity of the water, contrary to the idea that motions can only be relative, and that there is no absolute motion.

When water percolates through limestone or other soluble carbonate rocks, it partially dissolves the rock and causes cave formation and characteristic stalactites and stalagmites and also forms hard water.

Cement sets or cures when mixed with water which causes a series of hydration chemical reactions.

Rapid correction of hypernatremia causes water to move into cells, leading to multiple cerebral hemorrhages, equally catastrophic as osmotic demyelination.

For iron rust to occur the metal has to be in contact with oxygen and water, although chemical reactions for this process are relatively complex and not all of them are completely understood, it is believed the causes are the following:

When the rains return and soils become wet, the osmotic gradient between the bacterial cells and the soil water causes the cells to gain water quickly.

Cold weather causes water trapped in tiny rock cracks to freeze and expand, breaking the rock into several pieces.

This increased runoff, in addition to eroding and degrading the land that it flows over, also causes major disruption to surrounding watersheds by altering the volume and rate of water that flows through them, and filling them with chemically polluted sedimentation.

The increased flow of water through local waterways also causes a large increase in the rate of bank erosion.

The water contained in the plant stem expands and causes long cracks along the stem.

This turning of the water causes higher pressure on the bottom and reduced pressure on the top of the foil.

The momentum of the water flow in the supply pipe against the now closed waste valve causes a water hammer that raises the pressure in the pump, opens the delivery valve, and forces some water to flow into the delivery pipe.

Sometimes this addition causes both substance and water molecule to split into two parts.

There are various circulatory causes, including alteration of the voltage-gated potassium channel, as in arsenic poisoning from drinking water.

Besides treating the underlying causes such as potassium deficiency or arsenic contamination of drinking water, the first line treatment of erectile dysfunction consists of a trial of PDE5 inhibitor drugs ( the first of which was sildenafil or Viagra ).
