Mechanisms of observed spatial heterogeneity in rainfall variability over the winter rainfall zone of South Africa
… (WRZ) has emerged in the wake of the 2015–2017 “Day Zero” drought and water crisis. However, this has yielded little insight into the spatial heterogeneity in WRZ climatological seasonality and rainfall variability or their drivers, despite such understanding being crucial for interpreting past …

Exploring impacts and effectiveness of the City of Cape Town’s interventions on household water use practices during the drought
… restrictions, increased water tariffs, and the Day Zero communication campaign. However, little is known about how effective these measures were at encouraging people to save water. There is no clear documentation of how the public understands, interprets and incorporates these mechanisms into …

Compensation in movement behaviours following exercise of different intensities in older adults
… at baseline (two weeks prior to exercise), day zero (the day of exercise), and the subsequent three days. Overall, compensation was observed in all movement behaviours but sleep. It appears that the greatest compensation occurred following SPRT, with increases in ST and decreases in LPA and …

Investigating the use of CO-oximetry for simultaneous measurement of carboxyhaemoglobin and methaemoglobin in post-mortem blood
… at 4°C or –80°C and retrieved from storage on days 0, 1, 4, 7, 14, and 30, for analysis. While COHb remained stable in all storage conditions over a 30-day period, this was not true for MetHb. When samples were stored at 4°C, a rapid increase followed by a gradual decline was observed for MetHb …

Post-Weaning, Early Gestation Sows: Housing and Welfare
… We coded fourteen sow behaviors from day zero post weaning until day seven post weaning. Included in the study were fifty-three subjects in five batches. Each sow was recorded using scan sampling and instantaneous recording on day one, three, four and seven post-weaning every 5 minutes …

Generation of focal Depdc5 knockout mouse model and implications for focal epilepsy
… into the unilateral motor cortex of postnatal day zero or day one Depdc5 floxed (Depdc5c/c or Depdc5c/-) mouse pups. We confirmed a significant reduction in DEPDC5 levels and increased mTOR activity in the AAV-Cre injected hemisphere compared to the contralateral hemisphere or control AAV-GFP …

A flood of communications in a drought: a frame analysis of the City of Cape Town's communications during the 2017-2018 water crisis
… and household – water consumption which delayed Day Zero (when water supply would be cut-off and daily water rations would only be available at collection points for the public). The key implication of this study is that despite contradictions, idiosyncrasies and lack of planning, a heterogenous …

The Role of ERK5 in Dopamine Neuronal Survival
… phosphorylated ERK5 was observed at postnatal day zero (PND0) in all dopaminergic regions, which declined with the postnatal development. However, expression of total ERK1 and ERK2 increased with the postnatal development. An increase in the p-ERK1 and p-ERK2 peak was observed in both …

Cellular and molecular mechanisms underlying anesthetic-induced cytotoxicity, and their impact on learning and memory
… were extracted from rat pups at postnatal day zero, and these were then exposed to various clinically relevant concentrations of sevoflurane and dexmedetomidine (DEX). Specifically, I tested sevoflurane, to determine its effects on cell viability, growth, synapse formation, mitochondrial …

A CMIP5 Model Selection Specific to South Africa's Winter Rainfall Zone
… metrics to assess models against, the ‘Day Zero' drought is used as a characteristic episode. Here initially the extensive literature produced subsequent to the drought has been drawn on to identify and evaluate relevant regional process metrics, before utilising the anomalous conditions …

Using Hi-Spots to investigate in vitro network dysfunction in Cysteine String Protein ? knockout mice
… and re-aggregation. Hi-Spots made from postnatal day zero (P0) rats self organised into a complex 3D tissue-like structure containing anatomically synaptically-interconnected neurons, astroglia and microglia. This CNS analogue of brain tissue provides for the emergence of a co-ordinated excitatory …

How has environmental violence been experienced during the Cape Town water crisis using the Newlands Spring as a case-study
… which mostly related to the media campaign for Day Zero. Although no violent conflict on a mass scale has transpired as a result of the ongoing water crisis, there have been cases of civil violence. From protests at the greater Cape Town scale to physical altercations witnessed at Newlands …

Investigating the potential for utilising a water equity metric to benchmark differential access in Global South cities: a case study of Cape Town
In the wake of the day-zero drought the City of Cape Town (CCT or the City) has made the commitment to become water sensitive in its Water Strategy (CCT, 2019). According to the United Nations SDG 6.1, universal access to water has to take priority in any form of water policy. This is reflected in …

Extension and verification of the PWM_SA model to incorporate SANI-specific bioprocesses using experimental data from the Hong Kong SANI saline sewage treatment pilot plant.
… and pollution challenges. Cape Town's 2018 "Day Zero" crisis high lighted the need for innovative solutions. Adapting Hong Kong's SANI system, proven effective for saline wastewater treatment, offers a sustainable approach to conserve fresh water and enhance resilience. This study extends the …

An analysis of anomalously wet summers in the South Western Cape of South Africa
… from an extended dry period, known as the ‘Day Zero Drought' during 2015-2018, where greater Cape Town nearly ran out of piped water supply. Despite most rainfall in the SWC occurring from MaySeptember, considerable rainfall events have been known to occur during the summer (October-March). …

Genetic Analysis of Variation in Neuron Number
… number by counting ganglion cells at postnatal day zero. Approximately 77% of the variation among adult strains result from differences in the production of ganglion cells. Thus, the variation in adult ganglion cell number among inbred mouse strains results predominantly from differences in cell …
