A plant nutrient is a chemical element that is essential for plant growth and reproduction. Essential
element is a term often used to identify a plant nutrient. The term nutrient implies essentiality, so it
is redundant to call these elements essential nutrients. Commonly, for an element to be a nutrient,
it must fit certain criteria. The principal criterion is that the element must be required for a plant to
complete its life cycle. The second criterion is that no other element substitutes fully for the element
being considered as a nutrient.
Sedation is the important factor in comfort of brain trauma patients. Insuffient sedation
causes hypertension, tachycardia, hypoxia, hypercapnia and uncomfortable with ventilator.
On the other hand excess sedation causes hypotansion, bradycardia, coma, respiratory
depresion, ileus, renal insufficiency, veinous stasis and immunosupression.
For the patients in the critical care unit firstly nonpharmacological method should be
experinced for sedation. The patients should be frequently oriented.
This paper reviews the use of diagnostics in buildings, both in commissioning and in operations and maintenance. The difference between fault detection and fault diagnosis is defined. The kinds of fault that can arise at different stages of the building life cycle are described and the ways that these different kinds of fault can be detected are discussed. Other issues addressed include manual and automatic methods and whole building vs. component-level approaches.
In the late 1980’s, a considerable amount of research addressing the
effects of acidic deposition was begun, much of it related to the Congressionally
mandated National Atmospheric Precipitation Assessment Program
(NAPAP). As a result of the 10-year NAPAP program, effects on human
health, materials, structures, visibility and terrestrial and aquatic ecosystems
were evaluated. As a result of NAPAP funded research, negative effects of
acidic deposition were documented on freshwater lakes in the Adirondacks
and on the red spruce of the Adirondacks and northern Appalachians....
