However, because of their sensitivity to the magnetic fields, inadequate long-term durability especially in harsh environments, difficulties in installation on existing structures, and maintenance cost, installation of strain gauges is not always possible for all structural components.
However, the commercialization of PEFCs still faces three critical obstacles: high cost, insufficient activity, and inadequate long-term durability.
The commercialization of PEFCs encounters three critical obstacles, viz., high cost, insufficient activity, and inadequate long-term durability.
Production of PET-75D LLINs is faster and cheaper than production of PE-LLINs, 18 thereby giving it a competitive advantage over PE LLINs, and resulting in an uneven marketplace with a prevalence of inadequate LLINs regarding durability and serviceable life.
The difference in Id2 values between durable vs. non-durable mudrocks can sometimes be very small, due to the fact that fragments of material retained in the test drum can be larger than 2 mm making the slake durability test inadequate to quantify durability of mudrocks.
Inadequate performance, short term durability and high cost of polymer electrolyte membrane (PEM) are the major roadblocks that need to be resolved for successful commercialization of high temperature PEM fuel cell.
Patients remain inadequately treated, because existing therapies have a number of shortcomings, including inadequate efficacy in glucose lowering, limited durability of glycemic response, inconvenient dosing regimens, and safety and tolerability issues.
The US Army Armored Board released a critical report on the Locust in September 1943, stating that it was inadequate in the areas of reliability and durability, and indicating that it would not be able to be successfully used during airborne operations.
The structures that were built after World War II had little attention paid to durability issues and the U.S, and Japan had inadequate knowledge of seismic design.
