A GHG Metric Methodology to Assess Onsite Buildings Non-Potable Water System for Outdoor Landscape Use
This paper documents a water:energy greenhouse gas (GHG) metric methodology for a decentralized non-potable water system that was developed as part of a Professional Doctorate in Engineering (DEng) research project by the first author. The project identified the need to investigate the challenges in changing the use of potable water to recycled water for landscape irrigation (LI) and for water features (WFs) at a medical facility case study (MFCS) in Abu Dhabi (AD) (the capital city of the United Arab Emirates (UAE). The drivers for the research project were based on the need for AD to decrease desalinated potable water as well as reduce the environmental impact and operational costs associated with the processing and use of desalinated water. Thus, the aim of the research discussed and presented in this paper was to measure the impact of using recycled and onsite non-potable water sources at the MFCS to alleviate the use of desalinated potable water and reduce associated energy consumption, operational costs, and GHG emissions (latterly in terms of carbon dioxide equivalent (CO2e), for LI and WFs. The analysis of three case scenarios at the MFCS compared different approaches to alleviate energy use, costs, and GHG impacts for the use of recycled water in LI and WFs against a baseline. The findings led to a proposed sustainable water conservation and reuse (SWC) strategy, which helped save 50% desalinated potable water for LI use by soil improvement, building water system audits, and alternate non-potable water reuse. The recommendations for this paper are to develop a SWC strategy forming the basis for a water protocol by the competent authority for regional medical facilities including an assessment methodology for building decentralized non-potable water systems to measure their energy, GHG emissions and financial impact

Tracking Adaptation and Measuring Development in Kenya
Tracking Adaptation and Measuring Development (TAMD) is a twin-track framework that evaluates adaptation success as a combination of how widely and how well countries or institutions manage climate risks (Track 1) and how successful adaptation interventions are in reducing climate vulnerability and in keeping development on course (Track 2). With this twin-track approach, TAMD can be used to assess whether climate change adaptation leads to effective development, and also how development interventions can boost communities' capacity to adapt to climate change. Importantly, TAMD offers a flexible framework that can be used to generate bespoke frameworks for individual countries that can be tailored to specific contexts and used at different scales. This report compiles the results of TAMD feasibility testing phase in Kenya
Surgical techniques used for closure of perimembranous ventricular septal defects
Includes bibliographical references.A retrospective study was done at Red Cross Children's Hospital, Rondebosch, Cape Town in which two separate case-matched groups of children undergoing different surgical closure techniques for their isolated perimembranous ventricular septal defects were compared. Group I consisted of 77 children who had their VSDs closed between 1987 to 1990, mainly with a double velour dacron patch using interrupted alternating 5.0 silicone coated braided polyester suture ( Ticron®) and 5.0 polypropylene (Prolene®) pledgetted sutures (n=71). Five patients in Group I had bovine pericardium used and 1 patient's VSD was closed by a direct suture technique. Group II consisted of 93 children operated on between 1995 to 1998, and had their VSDs closed with a 0.6% glutaraldehyde-treated autologous pericardial patch using 5.0 polypropylene suture material in a continuous horizontal mattress suture without pledgets. Surgical time, discharge echocardiograms and follow up records were reviewed to assess the incidence of complications, reoperation or residual VSD needing further follow up
Temporal Interpolation via Motion Field Prediction
Navigated 2D multi-slice dynamic Magnetic Resonance (MR) imaging enables high
contrast 4D MR imaging during free breathing and provides in-vivo observations
for treatment planning and guidance. Navigator slices are vital for
retrospective stacking of 2D data slices in this method. However, they also
prolong the acquisition sessions. Temporal interpolation of navigator slices an
be used to reduce the number of navigator acquisitions without degrading
specificity in stacking. In this work, we propose a convolutional neural
network (CNN) based method for temporal interpolation via motion field
prediction. The proposed formulation incorporates the prior knowledge that a
motion field underlies changes in the image intensities over time. Previous
approaches that interpolate directly in the intensity space are prone to
produce blurry images or even remove structures in the images. Our method
avoids such problems and faithfully preserves the information in the image.
Further, an important advantage of our formulation is that it provides an
unsupervised estimation of bi-directional motion fields. We show that these
motion fields can be used to halve the number of registrations required during
4D reconstruction, thus substantially reducing the reconstruction time.Comment: Submitted to 1st Conference on Medical Imaging with Deep Learning

A BIOGRAPHY OF MOSES BUDAMBA MUDAVADI, 1923-1989
Moses Mudavadi a Loogoli or Maragoli born in Vihiga district was a grandee civil servant in colonial and nascent Kenya. The absence of an authentic and documented history on the legendary politician dubbed "King of Mululu" necessitated the study titled " A Biography of Moses Budamba Mudavadi, 1923 - 1989" The purpose of the study was to examine the life and times of Moses Mudavadi in the colonial era, the president Kenyatta epoch and the president Moi regime. The study anchored on Stogdill (1974) trait theory of leadership per se the big five factor model. It deployed historical research design, purposive and snowball sampling techniques that sampled 30 respondents from a target population of 307, 815 people - residents of Vihiga County in Kenya. The data was collected using field research and library search. . It was analyzed using narrative, conversation and content techniques; presented in prose. The findings actualized the findings. They showed that Moses Mudavadi was born in Vihiga district in 1923, was well educated during colonial era and served in the Ministry of education and tourism, made first entry in parliament in 1976 and a coveted minister in President Moi regime between 1979 and 1989. He demised in early1989. Had failures depicted by his temperamental character and blind support of President Moi`s populism that plummeted Kenya`s economy in 1980`s. His legacy was wrapped in his amiability, benevolence, projects he initiated and his renowned son cum formidable politician - Musalia Mudavadi. It was recommended that a book to be written from the thesis for posterity and another research of the kind to be carried out using a different design and methods
Occupational exposure to blood-borne or body fluid pathogens among medical interns at Addington Hospital, Durban
Background: Healthcare workers are at risk of transmission of hepatitis B and C and human immunodeficiency viruses following accidental exposure to blood and body fluids. Interns are a vulnerable group of healthcare workers, cited as having the highest incidence of accidental needle-stick injuries and splashes with blood or body fluids. The main reasonis thought to be a lack of experience and confidence, and underdeveloped dexterity skills, all of which increase risk of exposure. Since the introduction of the new two-year internship, to date no study has been carried out in South Africa comparing the incidence of occupational exposure between first- and second-year interns.Methods: A descriptive study design was devised and a structured questionnaire distributed to all interns employed at Addington Hospital in December 2008. All the interns had completed either one or two years of internship. Data were analysed using the SPSS software package and chi-square tests were applied for comparable variables.Results: The response rate was 83% (53/64). During 2008, 29 (55%) interns had at least one incident of accidental exposure to blood or body fluids. Eighteen (62%) were first-year interns and 11 (38%) were second-year interns (p < 0.01). In total, there were 42 exposures, of which 64% (27/42) were percutaneous and 36% (15/42) mucosal. First-yearinterns experienced 70% (19/27) of the needle-stick injuries and 73% (11/15) of the mucosal exposures (p < 0.01). A significant difference was noted between the first- and second-year interns (p < 0.01).Conclusion: The high level of exposure of interns to blood and blood products highlights the need for improvement in occupational health safety to prevent transmission of pathogens. Closer supervision of first-year interns and more focus on undergraduate awareness and skills development is necessary
