  1. Stage 1 is characterized of β-cell as confirm by at least <em>with normoglycemia and two islet autoantibodies  and is presymptomatic.  </em>
  2. Stage 2 is the β-cell autoimmunity with the presymptomatic  and dysglycemia. Beginning of symptomatic illness coming about <em>because of insulin lack in youngsters with type 1 diabetes.  </em>
  3. Stage 3 Reception of this arranging characterization gives an institutionalized scientific categorization to type 1 diabetes and may help <em>the improvement of treatments and the plan of clinical preliminaries to forestall symptomatic sickness.</em>

What is the relationship of nitrogen and grass
fredd [130]

Nitrogen is the major nutrient required by grass and is used to stimulate high growth rates and is key to achieving high yields, however if too much nitrogen is applied this can have a negative effects on quality.

High rates of nitrogen can also cause problems with silage fermentation due to excess nitrate having a negative impact on the fermentation process and will produce silage that is less palatable and the animals will be less keen to eat it.

<span> <span> </span> </span> <span> Nitrate is generally taken up by grasses quicker than it is incorporated into proteins and until used this excess known as luxury uptake is stored in the leaves. Excess nitrate will be present if insufficient time is allowed between application and mowing and can also occur under conditions of poor growth eg low light levels, cool temperatures. It is also a problem if there is a dry spell after application, when nitrate cannot be taken up by the roots, followed by a period of wet weather that results in luxury uptake. The plant cannot convert it to protein quickly enough so it accumulates in the plant. </span>

High rates of nitrogen may cause a reduction in crop sugars as they are used to provide energy for the increased rate of plant growth and for the manufacture of plant proteins and this increased growth rate may in turn lead to lower crop dry matter content although in practice this is often not significant.

Excess nitrate can be avoided by following the Grassland Rule to apply nitrogen at the rate of no more than 2.5 kg N/ha/day.
