In this paper, given a composite integer n, we propose a method of constructing quaternary low correlation zone(LCZ) sequences of period 2n− 1 from binary m-sequences of the same length. The correlation distribution of these new quaternary LCZ sequences is derived.
We consider the problem of finding bounds on the size of ternary and quaternary equidistant constant weight codes. We present a computer realization of an algorithm for solving the maximum clique problem. We use it for finding the exact values of the maximum size for ternary and quaternary equidistant constant weight codes for all open cases for n ≤ 10 are found.
A simple construction of quaternary hermitian self-orthogonal codes with parameters [2n + 1, k + 1] and [2n + 2, k + 2] from a given pair of self-orthogonal [n, k] codes, and its link to quantum codes is considered. As an application, an optimal quaternary linear [28, 20, 6] dual containing code is found that yields a new optimal [[28, 12, 6]] quantum code.

The concept of quaternary prevention (P4) refers to the idea that medicine has acquired the ability to damage through the proper exercise. Family medicine or general practice has the duty of recovering the ethical values and the exercise of a profession with the doctor-patient relationship serving to people's humanity. In the fourth Congress of Family and Community Medicine, held in Montevideo ...
Objectives: The aim of this study was to evaluate and compare the efficacy of 3 rd generation quaternary ammonium compounds and formaldehyde for fumigation of operation theatres. Materials and Methods: Fumigation and fogging of operation theatres by formaldehyde and 3 rd generation quaternary ammonium compounds respectively were done by standard procedures. A total of 144 samples (swabs as well...
Quaternary ammonium compounds, effective as sanitizing agents for food plant equipment under certain conditions, are not well suited as sanitizers for water of high mineral content. Mueller and Seeley (1951) have demonstrated under controlled conditions that various metallic cations can decrease the germicidal action of a quaternary in solution. Knowledge of how such interference takes place co...
The progress of antimicrobial therapy contributes to the development of strains of fungi resistant to antimicrobial drugs. Since cationic surfactants have been described as good antifungals, we present a SAR study of a novel homologous series of 140 bis-quaternary imidazolium chlorides and analyze them with respect to their biological activity against Candida albicans as one of the major opport...
In the title compound, C(19)H(26)O(2), the A ring adopts a chair conformation, whereas the B and C rings both adopt distorted half-chair conformations with the quaternary C atom common to both rings lying 0.577 (3) and 0.648 (3) Å out of the approximate plane defined by the remaining five C atoms (r.m.s. deviations = 0.1386 and 0.1156 Å) for the B and C rings, respectively. Mol-ecules are assem...
