abstract = {A comparative analysis of the composition of two species of Ocimum found in Makueni County, Kenya was undertaken. These were Ocimum kilimandscharicum (Mutaa) and Ocimum gratissimum (Mukandu). They are locally known by the names, Mutaa and Mukandu respectively. The Ocimum kilimandscharicum and Ocimum gratissimum were analysed qualitatively for the presence of minerals and phytochemicals. The phytochemicals analysed include reducing sugars, proteins, alkaloids, tannins, flavanoids, terpenoids and anthraquinones. The possible health benefits of the Ocimum species from Kenya were determined in view of the composition.

Addition of a drop of aqueous sodium hydroxide and ammonium hydroxide till in excess, to test for minerals present showed no precipitate. The Fehlings’ test for reducing sugars using 1ml Fehling’s solution No.1 added to 0.5ml of extract gave a green solution with a brown precipitate at the bottom. The precipitate was more for O. gratissimum than O. kilimansdcharicum. The biuret test for proteins was negative. A Wagner test (dilute iodine) for alkaloids gave a red-brown precipitate. Tannins/phenols were analysed using Ferric chloride. A dark green-black precipitate was formed. An orange solution was formed in the flavanoid test using Magnesium metal and dilute hydrochloric acid. Salkowski test for terpenoids using 2ml chloroform with 3ml concentrated sulphuric acid was done. Red –brown upper layer and lower layer with a colourless interface between was observed in O. kilimandscharicum. Similar observations were made in O. gratissimum with a pink lower layer and a red-brown top layer. The test for anthraquinones gave a brick-red layer at the bottom of the test tube with a black ring at the top. The brick red layer was slightly darker for sample B (Mukandu) compared to sample A (Mutaa).

In conclusion, the findings suggest the absence of proteins in both species of Ocimum. They point to the presence of calcium, magnesium, manganese, potassium and sodium minerals as confirmed by the flame test. Further, both species of Ocimum studied contain reducing sugars, alkaloids, tannins, flavanoids, terpenoids and anthraquinones. Variation in quantities of phytochemicals and minerals is suggested by the differences in colour intensities. In view of the findings Ocimum species in Kenya present great opportunities in the health sector that need to be explored. The phytochemical and minerals play significant roles in fighting microbes and ensuring a healthy body. A quantitative determination of the phytochemicals and minerals is required using Gas Chromatography-Mass Spectrometry (GC-MS) and Atomic Emission Spectrometry (AES) or Atomic Absorption Spectrometry (AAS) to determine the difference in the quantities between the two species. Further, isolation of active ingredients remains a great need.

Baro (2013) assert that for a medical practitioner or student to derive maximum benefits from information he/she must possess information literacy skills.

The objectives of the study were to: Examine the status of information literacy skills offered to medical undergraduate students at University of Nairobi and Moi University and ascertain the usefulness of these skills; examine the information literacy skills curriculum and assess the methods used in delivering the programme to undergraduate medical students in the two universities; analyze the adequacy of policies and regulations supporting information skills literacy programmes in the two institutions; determine the perceptions of undergraduate medical undergraduate students towards ILS; assess knowledge, skills and training possessed by staff engaged in facilitating ILS among medical undergraduate students; examine the role of ICT in facilitating and promoting information literacy skills among medical undergraduate students at the University of Nairobi and Moi University; and find out the challenges in ILS delivery and develop a framework to enhance ILS among medical undergraduate students in the University of Nairobi and Moi University.

The study was guided by both the Sauce Model as developed by Bond (2009) and the Six Frames of Information Literacy Education Model as developed by Bruce, Edwards & Lupton, (2015).

abstract = {Light Emitting Diodes (LEDs) are used in a variety of devices ranging from watches to solar home systems, as status indicators or communicative tools. They are typically designed to produce light in different colors and intensities. However, the communicative output varies across devices of similar or different functions. This variation and the sense that there is a wide array of expressions that can be employed, makes it hard for users of the devices to deduce the feedback easily. To address this gap, this paper looks at researches that highlight the importance of LEDs, their incorporation in various devices especially solar home systems and the challenges that arise from lack of standardization of their expressivity.

The findings show that LEDs are a dominant lighting technology and that through Internet of Things (IoT) they are going to become even more prevalent in user devices. The study also finds that solar home systems have become a lifeline for many people not covered by grid electricity, but their adoption can be affected by user perception. It is also found out that with their limited iconography these systems can be challenging to use and so this not only affects usability but also distribution because of the level of support needed.

This paper also investigates how Human Computer Interaction (HCI) frameworks can be employed to solve the identified usability challenges concludes that using a HCI framework to standardize the interface design of LED-touting devices can increase expressivity and user understanding of feedback relayed by these devices. Thus, manufacturers and industry governing bodies need to consider a universal vocabulary of light-based design that can be widely adopted to solve device usage challenges.},

abstract = {Women in the global south continue to experience the pain of Obstetric Fistula (OF), despite the increased use of new technology in the health sector. Obstetric Fistula is a medical condition in which a hole develops between the rectum and vagina (recto-vaginal fistula) or between the bladder and vagina (vesico-vaginal fistula) after a long and obstructed childbirth where medical care is not available. The World Health Organization shows that 50,000 to 100,000 women globally develop obstetric fistula each year. In the Sub Saharan Africa, about two million women have the condition with about 75000 new cases developing yearly.
