There exists an inherent difficulty in imparting knowledge on complex topics that are difficult to grasp for medical students who often have had minimal exposure to direct patient care.
It should be pointed out that there exist a number of difficulties encountered in the study of the stability for mild solution to neutral stochastic partial differential equations with delays since the neutral item is present.
Regardless of whether the additional disorder exists, the difficulty may still warrant intervention if it impairs the child's daily functioning.

There exists difficulty in monitoring the efficacy of bolus transport through the deglutitive apparatus in vivo, especially in patients which exhibit pathological difficulties.
In Algorithms 3.1 and 3.2, there still exists difficulty to implement the projections P C and P Q with respect to the defined norms, especially when C and Q are general closed convex sets.
For example, a large difference existed in difficulty dressing.
The failures listed include noise, cooling and calibration problems; finding targets in space where none existed; and difficulty distinguishing mock warheads from decoys.
Orange: some level of expressed demand exceeding available workforce - either through mal-distribution or insufficient workforce numbers, some vacancies exist, with difficulty in filling positions.
