Natural obstacles and available locations for carriers to lease space for their equipment and switching offices usually determine rate center boundaries, said Jack Ott, a numbering planner at U.S. West, which is in the midst of an area code split along city borders in Minnesota that is similar to Long Island's.
College administrators should help teachers make plans to solve problems and overcome obstacles with available resources [ 55, 58].
"Removing a simple obstacle like available sanitary towels makes a huge impact on the risk of girls missing school each month or dropping out altogether".
Specialist pastoral care, such as mentoring from other students who have overcome similar obstacles, should be available once young people reach university.
These include wind, runway surface conditions, landing or take-off distances required, the presence of obstacles, runway distance available, the existence and dimensions of runway safety areas.
The CHWs in every country named various transport related challenges as the top obstacles, (no transport available, transport always broken down, resupply point too far away, rainy season).
Recently, the advance in sensor technology makes a number of obstacle avoidance technologies available for visually impaired people [19].
On the other hand, Kurasin and Väljamäe showed that the degree of processivity of cellobiohydrolases was limited by the length of obstacle-free path available on the cellulose chain [ 19], and thus proposed that enzymes capable of faster desorption would be needed to overcome the retardation of hydrolysis by cellulases being blocked by obstacles.
Kurasin and Väljamäe measured Cel7A processivity and found cellulose hydrolysis was more than an order of magnitude lower than the values of the ratio of catalytic and dissociation rate constants, suggesting that the length of the obstacle-free path available for a processive run on a cellulose chain limits the processivity of cellobiohydrolase [ 52].
But nevertheless, the emission densities and short emission lifetimes present obstacles for the practically available electron field emitters based on CNTs.
