night in the case of long-term stays, it is possible to negotiate the price per night. this is because in such situation, the hotel bears slightly lower costs than usual, i.e. compared to a scenario when a person moves out and another moves in straight after. frequent cleaning and re-supply are the primary...
and ( ) chromosomal mutation in cultured mammalian cells and/or bone marrow within living mice. some of the assays within this second category can also detect aneuploidy. although these assays do not detect mutations in germ cells, they are used primarily because of the extra cost and complexity of...
"they have too few cops, too few prison cells, too few programs to help our children avoid crime," he said. he then addressed critics in the media who argued that everything he was proposing in the bill had been tried before....
other cells when mounting an immune response. a different population of t cells, the cd + t cells, function as "helper cells". unlike cd + killer t cells, these cd + helper t cells function by indirectly killing cells identified as foreign: they determine if and how other parts of the immune system respond...
rigidity. these motor symptoms can seriously affect a person's quality of life, so specialists have put a lot of work into finding ways of lessening their effects. so far, the prevalent view among parkinson's disease specialists has been that the motor symptoms occur when dopaminergic neurons — the brain cells...
-percent rate. alaska overstated the federal share of ihs medicaid expenditures by more than $ million because of data entry errors. in similar audits in oregon and south carolina, we found that although the state agencies correctly claimed ihs expenditures, they incorrectly claimed aca enhanced primary...
from our sun should be one of the most significant and free source of alternative energy available . every year trillion watts of sun energy reaches the earth surface . if less than % of earth landed surface is covered with energy harvesting device with just % conversion efficiency , like solar power cells...

[ ] b cells and t cells are derived from the same multipotent hematopoietic stem cells , and are morphologically indistinguishable from one another until after they are activated. b cells play a large role in the humoral immune response , whereas...
