Lower Cretaceous marine isopods (Isopoda: Cirolanidae, Sphaeromatidae) from the San Juan Raya and Tlayúa formations, Puebla, Mexico
(Oxford Univ Press, 2019)The fossil record of marine isopods is rather scarce and specimens are frequently incomplete. Our research for the paleobiota of the San Juan Raya Formation led to the finding of three species of marine isopods whose age, ... -
LQ control for coordinated linear systems
(IEEE, 2014)Coordinated linear systems are a special class of hierarchical linear systems, with a strict top-to-bottom information structure. The LQ problem over all structure-preserving static state feedbacks is discussed. The ... -
LTI modelling of active magnetic bearings by means of system identification
(SAIEE Publications, 2011)A relatively unknown phenomenon in active magnetic bearings (AMBs) is that the frequency content of their rotor position signal can induce nonlinear behaviour in the bearings. The existence of such frequency-induced nonlinear ... -
Lucky Marais: die verpersoonliking van kameleontiese manlikheid
(AOSIS, 2015)Hierdie artikel fokus op die representasie van manlikheidsbeelde in Eben Venter se roman Santa Gamka (2009) en meer spesifiek op die uitbeelding van die veelfasettigheid van manlikheid in die hoofkarakter Lucky Marais. Die ... -
The Lukan covenant concept: the basis of Israel's mandate in Luke-Acts
(AOSIS, 2013)Upon analysis of Luke's Gospel and the Acts of the Apostles conjoined theoretically in the reading event, the basis of Israel's mandate became pellucid in Lukan terms. This kind of analysis required the viable assumption ... -
Lung function, inflammation and cardiovascular mortality in Africans
(Wiley, 2016)Background The link between impaired lung function and cardiovascular outcome is well established in European and American populations. It is possible that this association may be driven by a systemic spillover of ... -
Lure and infect strategy for application of entomopathogenic fungus for the control of bean flower thrips in cowpea
(Elsevier, 2017)The efficacy of spot spray and cover spray applications of Metarhizium anisopliae (Metsch.) Sorok. in combination with the thrips attractant Lurem-TR (methyl-isonicotinate) was compared in field experiments for the management ... -

Machine learning digital soil mapping to inform gully erosion mitigation measures in the Eastern Cape, South Africa
(Elsevier, 2020)Soil erosion is probably the most common form of land degradation, leading to on and off site detrimental effects, such as an increase in river sediment load which have been shown to drastically decrease dam storage capacity. ... -
Machine learning for radio frequency interference mitigation using polarization
(IEEE, 2017)Radio frequency interference (RFI) is electromagnetic interference (EMI) from signals in the radio frequencies of the electromagnetic spectrum. RFI reduces the sensitivity of radio telescope and produces artefacts in ... -
Macro and trace elements of 26 browse species growing in semi-arid grazing lands of Eastern Cape, South Africa
(National Inquiry Services Centre (NISC), 2017)Leaves and twigs from woody plants provide essential nutrients to range animals. We examined variation in the mineral status of 26 woody species, and the influence of harvesting height as well as the interactions of the ... -
Macrobenthic communities in selected river-dominated estuaries in KwaZulu-Natal, South Africa: effects of contrasting environmental variables and seasonal flow changes
(CERF, 2020)Globally, estuaries are ecologically important, but many are threatened by anthropogenic activities. Macrozoobenthos organisms are suitable ecological indicators in estuaries because they can detect the effects of stress ... -
Macrocyclic inhibitor for corrosion of N80 steel in 3.5% NaCl solution saturated with CO2
(Elsevier, 2016)The inhibition of the corrosion of N80 steel in 3.5 wt.% NaCl solution saturated with CO2 by the 1,2,4,7,9,10-hexaazacyclo-pentadeca-10,15-dien-3,5,6,8-tetraone (HPT) has been studied using Fourier transform infrared ... -
Macroinvertebrate variation in endorheic depression wetlands in North West and Mpumalanga provinces, South Africa
(Natl Inquiry Services Centre Pty Ltd, 2015)Aquatic macroinvertebrates are rarely used in wetland assessments due to their variation. However, in terms of biodiversity, these invertebrates form an important component of wetland fauna. Spatial and temporal variation of ... -
