A frequent problem encountered in crystallizers is the control of the crystal size distribution (CSD) produced in the crystallizer.
A frequent problem encountered in rare diseases such as SSc is the difficulty in obtaining adequate patient numbers.
Another frequent problem encountered during genome annotation is the identification of a CDS located in two different reading frames that clearly encodes a unique, conserved protein.
Under the "others" category, the most frequent problem encountered was the "insufficient awareness of health and diseases," accounting for 22% of all the cases.
The most frequent problem encountered was septal deviation, found in 14 patients (15%), followed by turbinate hypertrophy in 6 patients (7%).
Structural pathology was found in 62% of RP patients, with septal deviation being the most frequent problem encountered (54%), followed by internal nasal valve dysfunction (14%).
A frequent problem encountered by clinicians is that patients appearing to have the same disease may not respond to the same treatment.
The most frequent problem encountered was septal deviation, found in 145 patients (54%), followed by internal nasal valve dysfunction in 38 patients (14%), inferior turbinate hypertrophy in 30 patients (11%), and external nasal valve dysfunction in 21 patients (8%).
Excessive torque/drag, upright equivalent circulation densities, hindering drillpipe sliding which results in limiting the lateral reach of the well, lost circulation, barite sag, inefficient hole cleaning and frequent sticking are some of the engineering problems encountered while drilling horizontally.
