UNICEF has sought additional financial support to address the ongoing lack of food and water, a shortage of medicines, a need for generators and supplies to repair damaged homes and schools, support needed for the most disadvantaged and displaced families, a need for psycho-social support particularly to children.
Intermittent wind and sun power creates a need for backup generators, while playing havoc with business models that justify investing in them.
The storm's aftermath also revealed a need for emergency generators to run at least one elevator in tall residential buildings and to pump water to high floors so the buildings remain habitable after a severe storm, some owners said.
Customers are paying more for their electricity while the generators are earning less, there is a need for massive investment in new power plants and power lines as ageing nuclear and coal plants come offline and rock-bottom carbon prices encourage the use of more polluting coal instead of cleaner gas.
There is a need for continuous adjustment of generator output as the load demand varies.
Novel radioisotopes such as Ga, Rb, or Cu can be produced on-demand from a radioisotope generator without the need for an on-site cyclotron and may serve as radionuclides for PET.
In a recent prospective US registry of pacemaker/ICD generator replacements, the need for an additional lead increased the rate of major complications from 4.0 to 15.3%.
The labeling procedures are straightforward and efficient, thanks to the low elution volume and high purity of the generator eluate (no need for fractionation or post-elution purification).
Siemens has begun selling a three-megawatt turbine using a so-called direct-drive system that replaces the conventional high-speed generator with a low-speed generator that eliminates the need for a gearbox.
When designing the hierarchical control structure of MTDC systems, those control approaches inspired by AC grids allow power converters to operate independently, in a similar manner to AC power generators, without the need for inter-station communications [38].
