Perspectives on waiting times in an antenatal clinic: A case study in the Western Cape

Background: Antenatal care (ANC) is vital in reducing maternal and neonatal morbidity and mortality. Globally, 85% of women had one ANC visit with a skilled birth attendant and only 58% received the recommended four ANC visits. Long waiting times (LWTs) in the antenatal clinic affects the utilisation of the service. Long waiting times are viewed as a significant barrier to ANC utilisation and needs further investigation. Aim: The aim of this study was to explore and describe the contextual realities within the antenatal clinic that influenced waiting times (WTs). Setting: This study was conducted in an antenatal clinic, within a Midwife Obstetric Unit (MOU), Western Cape, South Africa. Methods: This study utilised a qualitative methodology with a single case study design with three embedded units of analysis. Purposive sampling was used to recruit the participants. Data were collected through unstructured observation and semi-structured interviews with pregnant women and midwives. Interviews were audio recorded, transcribed and analysed using the framework method. Results: The antenatal clinics had LWTs. The barriers to WTs were related to staff factors, patient factors, operational factors, communication, equipment and infrastructure and other research participant recruitment. Conclusion: The factors that influenced WTs are multifaceted and interrelated. Many of the factors influencing the WTs could be remedied by implementing appropriate workflow strategies, improving communication and increasing equipment availability. The findings can be used to develop waiting time guidelines and improve WTs in the antenatal clinic

Temperature dependent characterization of optical fibres for distributed temperature sensing in hot geothermal wells

This study was performed in order to select a proper fibre for the application of a distributed temperature sensing system within a hot geothermal well in Iceland. Commercially available high temperature graded index fibres have been tested under in-situ temperature conditions. Experiments have been performed with four different polyimide coated fibres, a fibre with an aluminum coating and a fibre with a gold coating. To select a fibre, the relationship between attenuation, temperature, and time has been analyzed together with SEM micrographs. On the basis of these experiments, polyimide fibres have been chosen for utilisation. Further tests in ambient and inert atmosphere have been conducted with two polyimide coated fibres to set an operating temperature limit for these fibres. SEM micrographs, together with coating colour changes have been used to characterize the high temperature performance of the fibres. A novel cable design has been developed, a deployment strategy has been worked out and a suitable well for deployment has been selected.Comment: PACS: 42.81.Pa, 93.85.Fg, 47.80.Fg, 91.35.Dc, 07.20.Dt, 07.60.V

Rapid faults detection for controlling multi-terminal high voltage DC grids under AC grid contingencies

To control power flow for integration of distributed energy onto urban power grids, rapid and accurate detection of the amplitude, phase-angle, and frequency offset of the grid voltage's positive and negative sequence components especially under grid fault conditions are more significant. This paper presents a new faults detection method that is capable of tracking signal deviations on the grid-voltage accurately and rapidly even in the case that bus-voltage contains high order harmonics and random noises. The experimental results verify the validity of the proposed method under various grid-fault conditions

Chiral Supergravity

We study the linearized approximation of N=1 topologically massive supergravity around AdS3. Linearized gravitino fields are explicitly constructed. For appropriate boundary conditions, the conserved charges demonstrate chiral behavior, so that chiral gravity can be consistently extended to chiral supergravity.Comment: 30 page

An Update on Current Resuscitation Council (UK) Guidelines.

On 15 October 2015, The Resuscitation Council (UK) published new resuscitation guidelines following the review of resuscitation science by the International Liaison Committee on Resuscitation (ILCOR). The 2015 guidelines emphasize the importance of interactions between the emergency medical dispatcher, the bystander who provides cardiopulmonary resuscitation (CPR) and the prompt deployment of an automated external defibrillator (AED); the co-ordination of these three elements is crucial to improving out-of-hospital cardiac arrest survival. Medical emergencies in dental practices are thought to occur on average once every 3−4 years per dentist in primary care. The GDC consider medical emergencies as a highly recommended topic for Continuing Professional Development (CPD) and recommend at least 10 hours in every CPD cycle. Clinical relevance: The publication of the updated guidelines serves as a reminder to the clinical team of the importance of being up to date with recognition and treatment of cardiac arrest and choking and how seamless interaction between members of both the dental and medical teams improves long-term outcomes for patients
