Diagnosing emerging fungal threats: a one health perspective
(Frontiers Media, 2018)Emerging fungal pathogens are a growing threat to global health, ecosystems, food security, and the world economy. Over the last century, environmental change and globalized transport, twinned with the increasing application ... -
Diagnosing relativistic particle acceleration in AGN jets
(AIP, 2017)Mildly relativistic, oblique shocks are generally considered to be among the most plausible sites of relativistic particle acceleration and the subsequent production of strongly variable, polarized multi-wavelength emission ... -
A diagnostic biomarker profile for fibromyalgia syndrome based on an NMR metabolomics study of selected patients and controls
(BioMed Central, 2017)Background: Fibromyalgia syndrome (FMS) is a chronic pain syndrome. A plausible pathogenesis of the disease is uncertain and the pursuit of measurable biomarkers for objective identification of affected individuals is a ... -
Diagnostic DIVA tests accompanying the Disabled Infectious Single Animal (DISA) vaccine platform for African horse sickness
(Elsevier, 2018)African Horse Sickness Virus (AHSV) (Orbivirus genus, Reoviridae family) causes high mortality in naïve domestic horses with enormous economic and socio-emotional impact. There are nine AHSV serotypes showing limited cross ... -
Diagnostic tests for the distribution of random effects in multivariate mixed effects model
(Taylor & Francis, 2016)Fourier methods are proposed for testing the distribution of random effects in classical and robust multivariate mixed effects models. The test statistics involve estimation of the characteristic function of random effects. ... -
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 ... -
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 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 ... -
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 ... -
Diatom types of REM 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 ... -
Diatoms as water quality indicators in the upper reaches of the Great Fish River, Eastern Cape, South Africa
(Taylor & Francis, 2015)This study focused on the spring-fed upper reaches of the economically important Great Fish River with the aim of determining if diatoms could be used for biomonitoring in semi-arid conditions in southern Africa. Five ... -
Diatoms associated with two South African kelp species: Ecklonia maxima and Laminaria pallida
(Taylor & Francis, 2019)Kelp forests are believed to host a large biomass of epiphytic fauna and flora, including diatoms, which constitute the base of aquatic food webs and play an important role in the transfer of energy to higher trophic levels. ... -
Diatoms on sea turtles and floating debris in the Persian Gulf (Western Asia)
(Taylor & Francis, 2020)The current study investigated diatom communities on juvenile green turtles foraging in neritic habitats around five Iranian islands. The primary objectives were to (1) compare species composition, growth form structure, ... -
Dichlorodiphenyltrichloroethane (DDT) levels in rat livers collected from a malaria vector control region
(Japanese Society of Veterinary Science, 2019)Dichlorodiphenyltrichloroethane (DDT) is an organochlorine insecticide that has been used for indoor residual spraying for the control of mosquito-borne diseases including malaria. However, due to its toxicity and ... -
Did bank capital regulation exacerbate the subprime mortgage crisis?
(Hindawi, 2009)This contribution is the second in a series of papers on discrete-time modeling of bank capital regulation and its connection with the subprime mortgage crisis (SMC). The latter was caused by, amongst other things, the ...
