Wadende, Pamela(Nordic Journal of Vocational Education and Training, 2025)
The article questions the feasibility of the universalist discourse on academic drift in
vocational education from the perspective of the Global North-South configuration. We
will discuss examples from Finland, Bangladesh, ...

Studies show that mental health promotion is an effective strategy that can reduce the burden of
mental health disorders and improve overall well-being in both children and adults. In addition
to promoting high levels ...
Marabi Maruti, Phidelis; Musyoki, Stanslaus Kiilu; Monari, Fred Nyamitago; Kosiyo, Paul M; Ouma, Collins(African Journal of Laboratory Medicine, 2024-09-17)
Background: Despite the significant burden of menorrhagia (bleeding > 80 mL every menstrual
cycle) among women in Western Kenya, it remains unknown whether coagulation disorders
are an important underlying cause of this ...
Kosiyo, Paul M; Marabi Maruti, Phidelis; Musyoki, Stanslaus Kiilu; Ouma, Collins(African Journal of Laboratory Medicine, 2025-04-10)
Background: Menorrhagia, characterised by menstrual blood loss exceeding 80 mL per cycle,
is a common issue in Western Kenya. However, there are insufficient data on how hormonal
disorders contribute to its occurrence. ...

Let n be a positive integer, yn 1 cyclotomic polynomial and Zq be a given finite field. In this study we
determined the number of cyclic codes over Z31. First, we partitioned the cyclotomic polynomial yn 1 using
cyclotomic ...
