Dialogues of healing in the management of psychosocial health challenges in an indigenous KhoiSan community
(North-West University, 2018)During the researcher's experiential learning in the KhoiSan community, it was noted that this community deals with various psychosocial challenges, despite the fact that there is no nurse, councillor or therapist in this ... -
Dialogues of memory, heritage and transformation: re-membering contested identities and spaces in Postcolonial South African and Zimbabwean White writings
(Taylor & Francis, 2016)The protean and contested symbols of Zimbabwean literature remain the land and invented heroes, including a hagiographic iconisation of shrines, best seen in the Zimbabwe ruins, the Zimbabwe Bird and the national heroes’ ... -
Diamond formation by carbon saturation in C–O–H fluids during cold subduction of oceanic lithosphere
(Elsevier, 2014)Microdiamonds in garnet of graphite-free ultrahigh pressure metamorphic (UHPM) rocks from Lago di Cignana (western Alps, Italy) represent the first occurrence of diamond in a low-temperature subduction complex of oceanic ... -
Diamond precipitation from ascending reduced fluids in the Kaapvaal lithosphere: thermodynamic constraints
(Elsevier, 2012)Previous research has shown that the Kaapvaal lithospheric mantle is generally reduced and characterised by a decreasing redox state with increasing depth. As a consequence, CO- H fluids in the Kaapvaal lithospheric ... -
Diaphragmatic-intercostal breathing and the occurrence of gastroesophageal reflux disease in singers
(2014)This article was inspired by our awareness of an increasing number of voice students and professional singers who specialize in Western art music and who present with symptoms relating to gastro-esophageal reflux disease ... -

Diaspora missiology : the emerging apostolic role of Chinese migrants in Africa and Middle East colligate with Trinitarian Missio Dei
(2015)Missio Dei is a phrase used to describe the mission of God, as revealed in Scripture. One of the key verses to understanding the ultimate goal of God’s mission is the vision of heaven given to the Apostle John in the Book ... -
Diatom communities in the High Arctic aquatic habitats of northern Spitsbergen (Svalbard)
(Springer, 2017)As High Arctic environments are particularly sensitive to global and regional climate changes, a growing number of studies have focused on that region. It has been shown that living and fossil diatoms can be successfully ... -
Diatom community structure and relationship with water quality in Lake Sibaya, KwaZulu-Natal, South Africa
(Elsevier, 2019)Monitoring of wetland ecosystems is crucial as these ecosystems provide numerous services and resources to both humans and the biota found therein. Wetlands are characterised by variations in inundation time and depth and ... -
Diatom diversity and response to water quality within the Makuleke Wetlands and Lake Sibaya
(North-West University (South Africa), Potchefstroom Campus, 2017)All forms of life are dependent on water for survival. South Africa is a water scare country, due to seasonal rainfall and high temperatures, thus it is important to manage water resources in such a way that it benefits ... -
Diatom diversity on the skin of frozen historic loggerhead sea turtle specimens
(MDPI, 2020): In recent years, biofilm-forming diatoms have received increased attention as sea turtle epibionts. However, most of the research has focused on carapace-associated taxa and communities, while less is known about diatoms ... -
A diatom functional-based approach to assess changing environmental conditions in temporary depressional wetlands
(Elsevier, 2017)Functional-based assessments to identify the effects of human-induced disturbances on diatom communities are increasingly used. However, information on the response of functional groups to natural disturbances in temporary ... -
Diatom teratologies as biomarkers of contamination: are all deformities ecologically meaningful?
(Elsevier, 2017)Contaminant-related stress on aquatic biota is difficult to assess when lethal impacts are not observed. Diatoms, by displaying deformities (teratologies) in their valves, have the potential to reflect sub-lethal responses ... -
The diatom types of M. Giffen from Kidd’s Beach, Eastern Cape, South Africa
(North-West University (South Africa), 2022)Marine littoral diatoms are rarely studied and are important in the littoral zone ecosystem. Diatoms contribute to numerous aquatic ecosystem functions including: primary productivity, sediment binding, and stability. ... -
Diatom types of R.E.M. Archibald from Lake Sibaya and Lake Nhlange, South Africa
(Taylor & Francis, 2020)Natural lakes are rarely found in South Africa and are usually restricted to coastal regions. One of the larger coastal lakes is Lake Sibaya, which is situated in North-Eastern Kwa-Zulu Natal, a subtropical summer rainfall ... -

Diatoms as indicators of historical water quality: a comparison of samples taken in the Wemmershoek catchment (Western Province, South Africa) in 1960 and 2008
(WRC (Water Research Commission), 2014)Historical diatom records provide a means of retrospectively determining water quality and inferring ecological condition in rivers and streams. In this study we re-sampled sites originally sampled 48 years previously. We ...
