  For positive integers $s$ and $L \geq 3$, Berkovich and Uncu (Ann. Comb. $23$
($2019$) $263$--$284$) conjectured an inequality between the sizes of two
closely related sets of partitions whose parts lie in the interval $\{s,
\ldots, L+s\}$. Further restrictions are placed on the sets by specifying
impermissible parts as well as a minimum part. The authors proved their
conjecture for the cases $s=1$ and $s=2$. In the present article, we prove the
conjecture for general $s$ by proving a stronger theorem. We also prove other
related conjectures found in the same paper.
