Abstract
This study examined the relationship between occupational stress and academic staff productivity in public tertiary educational institutions in Lagos State, with two tested hypotheses. With the study’s foundation anchored on correlational and descriptive research designs were adopted, its population comprised all academic staff in public tertiary educational institutions in Lagos State. The sample size was 700. Questionnaire was used to collect data after ensuring its validity and establishing their reliability using test-retest method. The questionnaire is named “Occupational Stress Questionnaire for Teachers” (OSQT). Analysis was carried out using inferential statistics of Pearson’s Product-Moment Correlation Analysis and Regression Analysis by using the Statistical Package for Social Science (SPSS) version 24.0. Findings indicate that there is no significant relationship between occupational stress and productivity among academic staff in public tertiary educational institutions in Lagos State; also, the findings shows that there is a significant difference in the extent to which the identified factors of teaching (workload), research and publications, and community service are responsible for occupational stress among academic staff in public tertiary educational institutions in Lagos State. It is concluded that occupational stress has a considerable influence on the lecturers’ productivity in tertiary educational institutions in Lagos State. The study therefore recommended that tertiary educational institution managers should ensure that lecturers are assigned duties in line with their carrying capacities.

Abstract
Uniformly accelerated reference systems are obtained. They are described by two types of metrics with nonzero curvature. These systems contain an arbitrary strictly positive differentiable function.

Methodological notes. Consistent definition of the local equivalence principle
Parana J. Sci. Educ., v.9, n.5, (17-19), August 1, 2023.
(Short Communication)
Abstract
The opinion that the mathematical training of physicists, even leading ones, is insufficient is confirmed. These are the claims of V. A. Fock and N. N. Bogolyubov was presented to Landau. Mathematics is not reduced to a set of formulas and solutions to equations. A new formulation of the local principle of equivalence of the gravitational field and the accelerated frame of reference based on the standard mathematical epsilon-delta method is proposed.

Antibiotics and Resistance Genes: Influencing the Microbial Ecosystem in the Gut (Mini-Review)
Parana J. Sci. Educ., v.9, n.5, (20-28), August 1, 2023.
Abstract
The normal flora of human gastrointestinal tract (GIT) bacterial have many roles in human health, most of which are beneficial or neutral for the host. The intestinal bacteria play a significant role of being traffickers in antibiotics which supports the hypothesis that intestinal bacterial not only exchange resistance genes among themselves but might also interact with bacteria that are passing through the colon, causing these bacteria to acquire and transmit antibiotic resistance genes. The human gastrointestinal tract is a massive reservoir of bacteria with a potential for both receiving and transferring antibiotic resistance genes. The increased use of fermented food products and probiotics, as food supplements and health promoting products containing massive amounts of bacteria acting as either donors and/or recipient of antibiotic resistance genes in the human gastrointestinal tract, also contributes to the emergence of antibiotic resistant strains.
