Objective: To determine health care seeking attitude and behaviour and the predictors of combined orthodox and traditional health care use among households in communities in Owerri, Imo State. Nigeria. Methods: A cross sectional design that used a multistage random sampling technique to select 500 participants from households in two communities in Owerri, Imo State. Data was collected using a pretested, semi structured questionnaire. Descriptive analyses were done with frequencies and summary statistics. Chi square statistics were computed to determine significant relationships and binary logistic regression was used to determine predictors of combined use. P was set at 0.05 significance level. Results: The results revealed that, while just more than half of the respondents (56.4%) had a moderate to good level of overall knowledge of health care, almost all of the respondents (96.2%) also had a moderate to good level of overall positive attitude towards seeking health care;with less than one third (29.4%) using combined orthodox and traditional health care treatments. It further revealed that, respondents who were female, traders and from households of polygamous families were significantly more likely to use combined orthodox and traditional health care treatments (p < 0.05) while those with a tertiary level of education, from households with a professional as head, having private water closet toilets and earning a monthly income of more than 50,000 Naira ($140) were significantly less likely to use combined orthodox and traditional health care treatments (p < 0.05). Conclusion: There is a need to be more sensitive to the realities of the combined use of orthodox and traditional treatments, as its use will be difficult to prevent because this behaviour is rooted in the traditional and cultural belief system of our societies.展开更多

C(S) denotes the set of all congruences on S. In this paper we introduce the concept of admissible triples for S, where admissible triples are constructed by the congruences on S/γ , the equivalences on E(S)/L and E(S)/R. The notation Ca(S) denotes the set of all admissible triple for S. We prove that every congruence ρ on S can be uniquely determined by the admissible triple induced by ρ, and there exists a lattice isomomorphism between C(S) and Ca(S).展开更多

As an analogy of the type W semi-groups in the class of abundant semigroups, we introduce the U-orthodox semigroups. It is shown that the maximum congruence μ contained in HU on U-orthodox semigroups can be determined. As a consequence, we show that a U-orthodox semigroup S can be expressed by the spined product of a Hall semigroup WU and a V-ample semigroup (T,V ). This theorem not only generalizes a known result of Hall-Yamada for orthodox semigroups but also generalizes another known result of El-Qallali and Fountain for type W semigroups.展开更多

Survival of Antiaris toxicaria axes rapidly decreased and that of immature maize embryos very slowly decreased with dehydration. To understand their different responses to dehydration, we examined the changes in mitochondria activity during dehydration. Although activities of cytochrome (Cyt) c oxidase and malate dehydrogenase of the A. toxicaria axis and maize embryo mitochondria decreased with dehydration, the parameters of maize embryo mitochondria were much higher than those of A. toxicaria, showing that the damage was more severe for the A. toxicaria axis mitochondria than for those of maize embryo. The state I and III respiration of the A. toxicaria axis mitochondria were higher than those of maize embryo, the former rapidly decreased, and the latter slowly decreased with dehydration. The proportion of Cyt c pathway to state III respiration for the A. toxicaria axis mitochondria was low and rapidly decreased with dehydration, and the proportion of alternative oxidase pathway was high and slightly increased with dehydration. In contrast, the proportion of Cyt c pathway for maize embryo mitochondria was high, and that of alternative oxidase pathway was low. Both pathways decreased slowly with dehydration.展开更多

However, the class of regular semigroups with inverse transversals does not belong to this variety. We now call this class of semigroups the ist-variety of semigroups, and denote it by IST . In this paper, we consider the class of orthodox semigroups with inverse transversals, which is a special ist-variety and is denoted by OIST . Some previous results given by Tang and Wang on this topic are extended. In particular, the structure of free bands with inverse transversals is investigated. Results of McAlister, McFadden, Blyth and Saito on semigroups with inverse transversals are hence generalized and enriched.展开更多
