Before a port is set, a lot of feasibility study, environmental study and stakeholder analysis is seriously carried out. Despite this, there are a number of triggers that may precipitate port relocation. The role of this paper is to establish the triggers of port relocation. The paper will begin with a literature review and a discussion on triggers of port relocation. Case studies of world port relocations will be addressed. The paper will cover the triggers of port relocation and the relative effects of each trigger on port relocation. Factors like economic, social, environmental, political, infrastructural, nautical will be addressed. Data will be collected by use of a structured questionnaire to assess the ranking of these triggers. The triggers will be arranged as per their order of effects Fri, 01 Mar 2024 00:00:00 GMT http://ir.mu.ac.ke:8080/jspui/handle/123456789/10321 2024-03-01T00:00:00Z http://ir.mu.ac.ke:8080/jspui/handle/123456789/10313 Title: A review on the characterization of silk fibers and their composites after Alkali treatment Authors: Sabore, Joel; Makonde, Huxley Mae; Mwasiagi, Josphat Igadwa; Ratanya, Scholastica Nkirote Abstract: Natural fibers are becoming a more viable alternative as people become more conscious of the negative effects that making and discarding synthetic fibers have on the environment and the rising expense of materials made from petroleum. Among the natural fibers, silk commands considerable respect. Silk is a proteinaceous polymer secretion in the form of a cocoon, consisting of a continuous filament. Researchers are paying more attention to natural fiber-reinforced polymer matrix composites because of their availability, low density, biodegradability, and good mechanical qualities. On the material characterization of silk fiber and its composites based on polymer matrices, a significant study has been done. Natural fibers have a low interfacial adhesion between the fiber and the matrix and are hydrophilic by nature. Researchers have employed chemical ways to alter the fiber surface to improve the drawbacks of natural fibers. This review paper focuses on the effect of alkali treatment on the material properties of silk fibers and their composites.

M.; Uto, O. Timothy; Olawole, O. C. Abstract: Half-Heusler compounds hold great promise for thermoelectricity due to their excellent thermal stability and electronic transport properties. This study unveils the physical characteristics of half-Heusler compounds XCoSi (X = V, Nb, Ta) as potential materials for thermoelectric using the Quantum ESPRESSO and PHONOPY codes with PBEsol-GGA correlation functional. The electronic band structure calculations revealed the semiconducting nature of the compounds with an indirect band gap (X → W) of size 0.55 eV, 0.84 eV, and 1.25 eV for VCoSi, NbCoSi, and TaCoSi, respectively. The XCoSi(X=V, Nb, Ta) compounds demonstrate dynamic and mechanical stability, with ionic bonds and predicted ductility of these alloys. Additionally, critical parameters for thermoelectric application are computed, including the Seebeck coefficient (S), electrical conductivity (σ), thermal conductivity (κ), and the figure of merit (ZT). At room temperature, both p-type and n-type XCoSi (X = V, Nb, Ta) exhibit figure of merit values close to unity: 0.96 for VCoSi, 0.98 for NbCoSi, and 0.99 for TaCoSi, based solely on the electronic contribution to thermal conductivity. Including the lattice thermal conductivity provides a more accurate assessment of the thermoelectric potential of XCoSi (X = V, Nb, Ta). Among them, VCoSi shows greater potential for thermoelectric applications compared to TaCoSi and NbCoSi.

Failure to report adverse events following immunization (AEFI) can lead to death and misconceptions about vaccine safety hence vaccine hesitancy. Alleged vaccine quality and safety issues must be dealt with rapidly and effectively. This study assessed level of knowledge and reporting of AEFI among healthcare workers and caregivers at Mengo Hospital, Kampala.
