Confronted with massive electrical shortfalls, limited access to outside material, and questionable domestic research and development, the North only manages to manufacture and export 1960s military technology.
The validity of relationships between concrete ingredients and supplementary cementing materials is questionable.
Unfettered speculation on the true motivations of the federal government to pursue political demonstrators is of limited and questionable utility, but the material consequences of such pursuits can be clearly tracked.
Although the focus of the majority of these investigations is on identifying mechanical properties of mixes containing waste materials, the judgment about the effectiveness of these waste materials on improving mechanical properties of the mixes is suspicious and questionable.
The rankings of binder and mixture parameters (Jnr, G∗/sinδ, softening point and FN) are the same only for Jnr and FN, and the applicability of G∗/sinδ to modified materials is questionable.
Currently there is a small number of useable materials, accuracy is questionable and the size of parts is also limited.
Memory is selective, unreliable and questionable.
Furthermore, all of the immunostaining they do show is questionable and likely non-specific staining (in the materials and methods the appropriate species-matched isotype control is not listed, the one that is listed is of incorrect species).
The star marks the questionable detection of an Inoviridae genome in a Caldiserica SAG, which could originate from another bacterium contaminating MDA reagents (see 'Materials and methods').
