Additionally, in the literature there is a lack of comparative analyses of the contributions to local air pollution from different technologies.
However, there is still a lack of scientific analyses of the accuracy of satellite based settlement monitoring resulting in low acceptance of this technology in the daily application, for example in tunnelling.
At present, there is a lack of reliable analyses and mass balances that would allow for quantification of the variable mixing fractions, the fraction of the extracted fracking fluid, and possible reaction products.
Consequently, there is a lack of independent analyses of the current and future savings from the use of biosimilars.
Moreover, there is a lack of systematic analyses that integrate DNA methylation changes with genetic/epigenetic factors (copy number variations (CNVs), microRNA (miRNA) expression and histone modification, etc).
This was mostly due to a retrospective study design, a small sample size, a poor definition of the study domain, an uncertain diagnosis of the determinant (that is, the occurrence of AF), and a lack of multivariable analyses when assessing risk factors.
But there is a lack of investigations analysing the effect of the additional normal stresses on the bending resistance of the corrugated web girders.
There is a lack of studies analysing the population of patients with poor-grade SAH, which indeed represent a special cohort of patients, particularly due to the different clinical course with extremely high mortality and morbidity rates as well as the undefined clear treatment protocol.
Our review clearly shows that there is a lack of advanced epidemiologic analyses.
However, there is a lack of any comparative analyses that examines the similarities and differences between different landscapes, and why these might exist.
