Barriers in relation to health insurance and the subsequent difficulties in obtaining services were identified in a number of participating countries.
Acid leaching of spent hydrodesulphurization (HDS) catalysts solubilizes efficiently all metals present in the catalyst; however, this methodology poses subsequent difficulties in achieving metals separation with high purity.
In spite of a poor entrepreneurial culture and subsequent difficulties in this area, the Portuguese people are extremely creative and with some guidance they reach their dreams easily.
The low contraceptive use and subsequent difficulties in fertility regulation are explained in the literature by various barriers.
The concept of efficiency itself is variously used by researchers with different scopes, causing subsequent difficulties in the comparison and generalization of findings [19].
It may be possible to use thermal cycling to reduce this problem, however this not necessarily advisable as it can introduce other problems – quench cooling may trap a high temperature phase in a metastable form, whereas thermal cycling will allow it to form a low-temperature pseudo-symmetric phase leading to subsequent difficulties in the analysis.
The effectiveness of this bond could be compromised because sealed dentin surfaces have the potential to strongly attach to resin-based provisional materials, suggesting that this type of provisional material should be avoided [6] due to subsequent difficulties in removing resin-based provisional restorations.
Due largely to their nocturnal behavior and the subsequent difficulties in accurately quantifying abundance, data about the population size or distribution patterns of slow lorises is limited.
This may be explained by incomplete or inaccurate reporting and the subsequent difficulties in assessing the methodological quality of trials [ 57, 58].
Most previous studies investigating the incorporation of topoisomerase-I inhibitors into first-line therapy of EOC have used triplet combinations, with subsequent difficulties in dose escalation owing to myelotoxicity (Herben et al, 1999; Cacciari et al, 2000; Bolis et al, 2001; Escobar et al, 2004).
