Beneficiaries in poor health or with the most severe disabilities were most likely to perceive access and cost difficulties, regardless of coverage type.
The high cost, difficulties, and possible dangers of providing dock and quay walls of the kind just described have always encouraged a search for alternative solutions that would eliminate the need for operations on or below the seabed.
In Hong Kong, respondents who were widowed were about 19 times more likely [OR=19.81, CI=5.37 73.05, p<0.001] to state that cost difficulties were not an issue on the last occasion they required to see a doctor/specialist than those who had never married.
Most conventional derivative-based color edge detectors have shortcomings such as high computational cost, difficulty in implementation and missing edges.
High cost, difficulty in execution, reduction in headroom, loss of aesthetic value, increase in self-weight, careful surface preparation, de-bonding failure are some of the innate limitations of these techniques.
MEMS devices offer small size and low power consumption and improved physical parameters such as FQ product; however, significant impediments to a large scale commercial adoption include: production cost, difficulty of implementation and signal transduction.
However, factors such as high cost, difficulty of integrating with Si substrate, and complicated fabrication process have drawn back the potential application of planar-type ZnO photodetectors.
However, NZVI was not feasible for wastewater treatment in practice due to its relatively high cost, difficulty to be stored and easiness to be oxidized.
Among the aforementioned methods, adsorption is considered to be one of the most appropriate techniques, but there are disadvantages to this method, including small capacity, high cost, difficulty for large-scale application, etc.
However, cost, difficulty of implementation, and other barriers impede adoption of such systems, and studies have documented low rates of technology acquisition and implementation in emergency department (ED) and other settings [2].
Current drug treatments of visceral leishmaniasis suffer from various drawbacks such as host toxicity, high cost, difficulty to administer and drug-resistance development.
