Appraisal of the Principles and Practices of Electronic Health Records (EHR) In Public Hospital. A Case of Narok County Hospital

The paper tries to investigate all the principles and practices in the management of the electronic medical records. ABSTRACT For many years, health records have been controlled through paper based systems which are vulnerable to destruction, wear and loss hence hinders adequate usability, retrieval and access. In addition, this made health processes to be time consuming and expensive, making the manual records more unreliable. In bid to mitigate these challenges, the Ministry of Health in Ke...

Design and Implementation of a Student Chat Information System

ABSTRACT Basically, it has been observed over the years that number of students live far away from the educational institutions as well as the lecturer who are few times occupied. Thus the main objective of this research work is to develop a general purpose interactive information system where information becomes easier and feedback faster, course materials and assignments also gotten at any location regardless of the time. The student chat information system makes use of Object Oriented Anal...

PHYTOCHEMICAL ANALYSIS AND ISOLATION OF COMPONENTS OF STEM-BARK OF CHRYSOPHYLLUM ALBIDUM (G.Don)

Chrysophyllum albidum (Sapotaceae) is known to possess bioactive compounds belonging to important phytochemical groups. This work aims at exploring the bioactive constituents of the stem-bark of Chrysophyllum albidum, and further investigating their phytochemical compositions. Stem bark of Chrysophyllum albidum was collected, dried, powdered and extracted with hexane for 13 hours using soxhlet extraction. This was concentrated using a rotary evaporator.

Antimicrobial Effect of Natural Honey and Mango Leave on Pathogenic Bacteria

ABSTRACT  Honey has since been found to possess antibacterial property and is therefore employed for wound and gastro-intestinal disease therapy. This study evaluates the antibacterial spectrum and efficacy of honey and compared with tetracycline.  Different concentrations (50, 75 and 100.0 %) of honey were studied in-vitro using Staphylococcus aureus, Klebsiella spp, Escherichia coli and Citrobacter spp. The data obtained showed the inhibitory action of honey with clear zones of inhibition...

Relating Geology and Geological Structures with Regional Episodes: Implication for Groundwater Exploration and Development around Kwal-Kanke Area, Jos Plateau

Abstract The  study  addressed  the  Geology  and  geological structures around  Kwal-Kanke  area  around  the  Jos  plateau. Three (3) rock types namely; Quaternary dolerite/basic rocks, aplo-pegmatitic  granite  gneiss  and  migmatite-gneiss  were delineated. The  quaternary  dolerites  and  the  aplo-pegmatitic granite  are  emplaced  in  form  of  dykes  with  lateral  extent greater than 3km trending NW-SE and conforms to the trend of the fractures around J...

EFFECTOF METHANOL EXTRACT OF cirtullus lanatus SEEDSON HEMATOLOGICAL PARAMETERS IN MODULATION OF DIHYDROTESTOSTERONE ESTRADIOL VELERATE INDUCED BENIGN PROSTATIC HYPERPLASIA IN MALE WISTAR RA

Citrullus lanatus is medicinal plants believed to have many agents acting in different ways for the health benefits of human. This study investigated the acute phytochemical contents and effect of the methanol extract on weight changes, relative organ weight, hematological parameters and biomarkers of prostate dysfunction. The result indicated the presence of alkaloids, terpenes, flavonoids, Reducing sugar, tannins and phenols. Acute toxicity studies showed that the extract was safe at 5000mg...

Jatropha Tanjorensis Leaf Extract as an Environmentally Friendly Mild Steel Corrosion Inhibitor in Acidic Medium

Abstract : The inhibition of the corrosion of mild steel in 1 M H2SO4 solution by Jatropha tanjorensis leaf extract (JTLE) has been studied using weight loss and hydrogen evolution techniques. The results obtained reveal that JTLE effectively inhibited the corrosion of mild steel in H2SO4 solution. The highest inhibition efficiency of 89.73% occurred at 5.0 g/L JTLE concentration at 333K by weight loss measurements. Inhibition efficiency was found to increase with increase in JTLE concent...
