M.; Uto, O. Timothy; Olawole, O. C. 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.

Using descriptive survey design and stratified randomsampling, data was collected from 20 publishing firms using questionnaires, personalinterviews, and content analysis of their websites. The research findings revealed thatmajority of the respondent firms were engaged in the e-publishing activities of onlineproduction, distribution, marketing, sales and customer service. Very few publishers havefully adopted e-book or e-journal publishing technologies and even though the majority ofthose which have adopted these technologies have their e-publications in Portable DocumentFile format. Organizational factors influencing the adoption of e-publishing among therespondent firms were; existence of innovation champions, availability of funds and marketdemands for e-publications. Yeas in existence, staff sizes and threat of competition fromother publishers were not considered significant influencing factors. The major challenges tothe adoption of e-publishing in Kenya are; high implementation cost of e-publishing, lack orhigh cost of electricity, inadequate awareness of the existence and use of e-resources and lowInternet skills among potential customers. Resistance by both authors and readers, fears ofpiracy and low market demands for e-publications were identified as impediments to thesuccess of e-publishing in Kenya. The researchers recommend that Kenyan publishers shouldbe more proactive so as to embrace e-book technology, reliable security codes to counterpiracy are used. Mass media should play a key role in disseminating information on theoperations, advantages and attributes of e-publishing. The Government of Kenya through theMinistry of Education should provide computers to public schools. The government shouldexpand Internet access and electricity supply especially in rural areas. Local publishersshould devise mechanisms for partnerships with foreign publishers who have successfullyembraced e-publishing technologies (1) (PDF) Organizational Factors Influencing the Adoption of Electronic Publishing Among Book and Journal Publishers in Kenya.
