Furthermore, the inclusion of this proxy of absolute poverty allows us to consider a socioeconomic variable for a larger sample of countries, avoiding the aforementioned possible bias regarding the non availability of socioeconomic inequality data for an important number of countries.
First, while refusal rates in the community cohort were low, and multiple contact attempts were made at all eligible households, including on Saturdays and Sundays, it is possible that non-availability may have biased the community sample toward those with no or less stable income sources; it is not clear whether such biases were amplified or reduced in the MVCT cohort.
Breeding for genetic resistance against aphids has not been possible owing to the non-availability of resistance source within the crossable germplasms and lack of knowledge of the genetics of the trait.
Comparison of serology data with the incidence of clinical disease was not possible due to the non-availability of baseline seropositivity in representative pre-pandemic sera, non-reliability of disease incidence estimates due to changing policies of sampling and testing of throat swab specimens at different time periods, and co-circulation of seasonal and pandemic viruses in the community.
The possible reason could be the non-availability of polar oxirane ring of EBR30 to function as compatibilizer because of the stoichiometric reaction between amino-group of APS and oxirane ring of EBR30 as represented in Scheme 4.
In practice, those alleles can be traced to origin by comprehensive genotyping of the pedigree, but expending those types of resources is not possible considering the cost and non-availability of DNA representing maternal lines.
Due to non-availability of accident data with respect to driving side in Rwanda, it was not possible to assess the incremental impacts of odd vehicles on road accidents using primary data.
non-availability of oxidative free radicals; 3.
The estimated monthly capacity factor values are multiplied by measured monthly machine availability and monthly grid availability given in Table 5 for adjusting the losses associated with machine non-availability and grid non-availability.
Especially a full availability of resources (see: CO7) requires strategies in case of non-availability (see: SY2).
