Concentrations of metallic elements in kidney, liver, and lung tissue of Indo-Pacific bottlenose dolphin Tursiops aduncus from coastal waters of Zanzibar, Tanzania
(Elsevier, 2017)Concentrations of metallic elements in kidney, liver and lung tissues of Indo-Pacific bottlenose dolphins Tursiops aduncus from coastal waters of Zanzibar were determined using inductively coupled plasma – optical emission ... -
Concentrations, distributions and critical level exceedance assessment of SO2, NO2 and O3 in South Africa
(Springer, 2010)South Africa has been identified as a source of industrial pollution that is significant at a global scale. This study was designed to provide quantitative information, by direct measurement, across northeastern South ... -
Concept analysis of collaboration in implementing problem-based learning in nursing education
(AOSIS, 2016)Objectives: The purpose of this concept analysis was to better understand and define collaboration as it relates to the implementation of problem-based learning (PBL). Methods: The process of concept analysis was conducted ... -
Concept confusion and concept discernment in basic magnetism using analogical reasoning
(IOP Publishing, 2017)Analogical reasoning is central to all learning, whether in daily life situations, in the classroom or while doing research. Although analogies can aid the learning process of making sense of phenomena and understanding ... -
The concept of ecosystem services in adaptive urban planning and design: a framework for supporting innovation
(Elsevier, 2014)Recent research and professional interest in planning for sustainable and resilient cities emphasizes the assessment of a broad spectrum of urban ecosystem services. While such assessments are useful to establish specific ... -
Conceptual Model: psychosocial implications of caring for people living with HIV among nurses
(Kamla-Raj, 2016)Nursing is an occupation that is subjected to a high degree of stress. Stress had been seen as a predictor of the nature of care provided by nurses caring for people living with Human Immunodeficiency Virus (HIV) (PLWH). ... -
Conceptualising and managing trade–offs in sustainability assessment
(ELSEVIER, 2013)One of the defining characteristics of sustainability assessment as a form of impact assessment is that it provides a forum for the explicit consideration of the trade-offs that are inherent in complex decision-making processes. ... -
Conceptualising the effectiveness of impact assessment processes
(Elsevier, 2013)This paper aims at conceptualising the effectiveness of impact assessment processes through the development of a literature-based framework of criteria to measure impact assessment effectiveness. Four categories of ... -
Concurrent class analysis identifies discriminatory variables from metabolomics data on isovaleric acidemia
(Springer, 2012)Metabolomics data are typically complex and high dimensional. Multivariate dimension-reducing techniques have thus been developed for analysing metabolomics data to disclose underlying relationships, with principal component ... -
Conductivity as an indicator of surface water quality in the proximity of ferrochrome smelters in South Africa
(WRC, 2015)South Africa is one of the leading ferrochrome (FeCr) producing countries. One of the main environmental and healthrelated issues associated with FeCr production is the possible generation of Cr(VI). However, Cr(VI) is ... -
Confirming the pest status of Trimen’s false tiger, Agoma trimenii (Felder) (Lepidoptera: Agaristidae), on grapevines in South Africa
(Entomological Society of Southern Africa, 2012)Various lepidopteran pests attack grapevines in South Africa, but they are mostly regarded as sporadic pests that seldom cause economic damage. The leaf-feeding silver-striped hawk moth, Hippotion celerio (Linneaus) ... -
Conflict dynamics within the gender spectrum of a large manufacturing company
(Taylor & Francis, 2017)The primary objective of this study was to investigate the perception and handling of interpersonal conflict within the gender spectrum compilation of biological sex and gender identity. The empirical analysis utilised a ... -
Conflicting traffic: characterization of the hazards of birds flying across an airport runway
(Wiley, 2016)Bird–aircraft collisions cost millions of dollars to aviation globally and cause deaths. We designed and tested a protocol to study the hazards to aircraft from birds flying across runways where aircraft rotate and climb ... -
Conflicts in adaptation: case studies from Nepal and the Maldives
(Emerald, 2019)Purpose Adaptation appears to be regarded as a panacea in policy circles to reduce the risk of impending crises resulting from contemporary changes, including but not restricted to climate change. Such conceptions can be ... -
Consensus ranking: an ICT security awareness
(Elsevier, 2008)There are many disciplines where the problem of consensus ranking plays a vital role. Decision-makers are frequently asked to express their preferences for a group of objects, e.g. new projects, new products, candidates ... -
Consensus sequence determination and elucidation of the evolutionary history of a rotavirus Wa variant reveal a close relationship to various Wa variants derived from the original Wa strain
(Elsevier, 2013)The consensus nucleotide sequence of a human rotavirus Wa strain, with only a partially known passage history, was determined with sequence-independent amplification and next generation 454 pyrosequencing. This rotavirus ... -
Conservation Laws and Exact Solutions of a Generalized Zakharov Kuznetsov Equation
(Mdpi Ag, 2015)In this paper, we study a generalized Zakharov–Kuznetsov equation in three variables, which has applications in the nonlinear development of ion-acoustic waves in a magnetized plasma. Conservation laws for this equation ... -
Conservation laws and solutions of a generalized coupled (2+1)-dimensional Burgers system
(Elsevier, 2017)In this paper we study a generalized coupled (2+1)-dimensional Burgers system, which is a nonlinear version of a bilinear system under some dependent variable transformations. It was introduced recently in the literature ... -
Conservation laws and traveling wave solutions of a generalized Nonlinear ZK-BBM equation
(Hindawi publishing corporation, 2014)We study a generalized two-dimensional nonlinear Zakharov-Kuznetsov-Benjamin-Bona-Mahony (ZK-BBM) equation, which is in fact Benjamin-Bona-Mahony equation formulated in the ZK sense. Conservation laws for this equation are ... -
