Annual rainfall exhibited no significant trends at most stations (p > 0.05), except for a notable decline at one eastern site. Seasonal rainfall and streamflow showed …

Numerical Simulation Of Corner Reinforced Concrete Column-Beam Joint With Differential Concrete Grades And Steel Fibres Under Monotonic Loading, Daudi S. Augustino, Emmanuel Safari Leo

Tanzania Journal of Engineering and Technology (TJET)

Structural elements are composed of joints that are essential for force transfer. In particular, for concrete structures, the column-beam joint is an integral section that requires insight due to the traditional use of different concrete grades, forming a strong-column-weak-beam (SCWB) system. A numerical model of the joint was developed in Abaqus to explore the axial load performance and damage tolerance of corner column-beam joints with different concrete grades under monotonic static loading. A concrete-damaged plasticity model (CDPM) was used to model the damage behaviour of concrete, utilising the available strain-stress models in literature and EuroCode 2. Results show that concrete …

The Syntax And Semantics Of Reciprocal Constructions In Chibarwe: A Lexical Mapping Account, Tendai Chirimaunga

Journal of Humanities and Social Sciences

Bantu languages have a robust structure, which is usually stated to be agglutinative, accommodates affixations of a wide range of morphemes both as prefixes (to the left of the root), as well suffixes (to the right of the root) before placing the terminal vowel. In their verbal morphology, the reciprocal is one of the many derivational affixes that have, however, not gained similar prominence as the study of the applicative and the causative construction. The thrust of this study is to investigate the syntax and semantics of reciprocal constructions in ChiBarwe, a marginalised cross-border language spoken in Zimbabwe and Mozambique. …
