However, there are several obstacles to this process because germ cells are relatively transcriptionally quiescent and prone to switching off transgene expression [ 52, 53].
The developmental process of becoming a mother, and the many potential obstacles to this process, were described in detail in Ramona Mercer's theory of Becoming a Mother (BAM) [ 6, 7].
Efforts are made to translate new knowledge and evidence-based practices into routine care, but there are a number of obstacles to this translation process.
However, the problem of high internal resistance (Rint), which results in low power density, is a technical obstacle related to this process, and the preferential conversion of the organic fraction by bioelectrogenesis remains unclear.
Despite their efficiency, the cost of the current lactic acid bio-processes is still an obstacle to this application (Miller et al., 2011 [2011
Obstacles to automating this process include technical difficulties in translating annotations into proper biochemical activities, and also the fact that methods for model refinement have been designed and applied separately for each type of experimental data.
Still, Mr. Monroe, who could not say how many of his museum's Indian works have so far been attributed, conceded that there are serious obstacles to the process.
Initially progress was greatest in the open-field areas, particularly the Paris Basin, where there were few physical obstacles to the process.
These "wind tails" are seen around boulders, where the rock acts as a natural obstacle to some process - forming a streak of material "downwind" of it.
