- Description: Prompt management of side effects is critical to supporting adherence to antiretroviral (ARV) medication. This study examines the impact of presenting side effect information using simple text combined with pictograms on sustained knowledge of ARV side effects over three months. Previously designed side effect pictograms, combined with simple text, were incorporated into a side effects panel within an ARV information leaflet. In a randomised controlled study, 116 limited literacy HIV patients taking ARVs were randomly allocated to either control (standard care) or intervention groups (standard care plus illustrated information). Side effect knowledge was assessed at baseline, and intervention patients received the illustrated leaflet. Knowledge was re-tested at one and three months. Interpretation of side effect pictograms was evaluated at one month.

- Description: We report the influence of dopants on the thermoluminescence of Sr2MgSi2O7. Samples studied comprise undoped Sr2MgSi2O7 and doped versions, namely, Sr2MgSi2O7:Dy3+, Sr2MgSi2O7:Eu3+, Sr2MgSi2O7:Tb3+ and Sr2MgSi2O7:Tb3+,Eu3+ phosphors. All samples show a broad glow peak near 60 °C when measured at 1 °C/s after irradiation to 10 Gy. The peak changes with partial heating, irradiation and fades between irradiation and measurement in a manner expected of a composite one. The behaviour is used to exemplify the analysis of a composite peak on the basis that particular features reflect those of the dominant component.

- Description: This paper examines internet memes as a unique form of narratives about political discourse in Nigeria. Through the use of social media platforms as a vehicle of political communication, internet memes about politics explore issues that contain visual metaphors aimed at provoking discourse and stimulate political participation. By employing semiotic theory, this paper examines 200 pictorial internet memes on Nigerian politics between 2015 and 2018. I argue that internet memes about politics are related to political cartoons in form and context. But unlike cartoons, memes require less artistic prowess and figurative expression in rendition but could achieve the same desire in viewers. Owing to their composition of easily digestible visual elements, they appeal to more audience who in turn could easily lend their voices to a popular meme by adding more textual or visual enhancement to create more layers of meaning.
