An n x m sonar sequence is a subset of the n x m grid with exactly one point in each column, such that the (r~) vectors determined by them are all distinct. We show that for fixed n the maximal m for which a sonar sequence exists satisfies n-Cn 11/20 < m < n + 4n 2/3 for all n and m > n + c log n log log n for infinitely many n. Another problem concerns the(More)
1. The fall in chlorine concentration of Dakin's hypochlorite solution is more rapid in contact with necrotic than in contact with normal tissue. 2. The fall in chlorine concentration of chloramine-T solution is very slight when applied to necrotic tissue and is negligible when applied to normal tissue. 3. The action of the hypochlorite solution on tissue(More)
1. Dakin's hypochlorite and chloramine-T solutions will protect pigeons against multiple fatal doses of the toxin of Bacillus welch when the antiseptic and the toxin are mixed in vitro and allowed to stand in contact for 5 minutes before injection. 2. The detoxicating action of the solutions is demonstrable also in the presence of serum. 3. Phenol solution,(More)
