A nonnative Palmer amaranth (Amaranthus palmeri) population in the Republic of South Africa is resistant to herbicides with different sites of action
(2022)Palmer amaranth (Amaranthus palmeri S. Watson) is not native to Africa. Based on the presence and persistence of A. palmeri populations, its invasive status in southern Africa is classified as “naturalized.” Globally, A. ... -
Nonparametric estimation of location and scale parameters
(Elsevier, 2012)Two random variables X and Y belong to the same location-scale family if there are constants μ and σ such that Y and μ+σX have the same distribution. In this paper we consider non-parametric estimation of the parameters μ ... -
Nonparametric estimation of the cross ratio function
(Springer, 2020)The cross ratio function (CRF) is a commonly used tool to describe local dependence between two correlated variables. Being a ratio of conditional hazards, the CRF can be rewritten in terms of (first and second derivatives ... -
A nonparametric point estimation technique using the m-out-of-n bootstrap
(SASA, 2018)We investigate a method which can be used to improve an existing point estimator by a modification of the estimator and by using the m-out-of-n bootstrap. The estimation method used, known as bootstrap robust aggregating ... -
Nonparametric probability weighted empirical characteristic function and applications
(Elsevier, 2016)We study certain properties of probability weighted quantities and suggest a nonparametric estimator of the probability weighted characteristic function introduced by Meintanis et al. (2014). Some properties of this estimator ... -
Nonparametric testing for no covariate effects in conditional copulas
(Taylor & Francis, 2017)In dependence modelling using conditional copulas, one often imposes the working assumption that the covariate influences the conditional copula solely through the marginal distributions. This so-called (pairwise) simplifying ... -
Nonuniform internal structure of fibrin fibers: protein density and bond density strongly decrease with increasing diameter
(Hindawi, 2017)Themajor structural component of a blood clot is ameshwork of fibrin fibers. It has long been thought that the internal structure of fibrin fibers is homogeneous; that is, the protein density and the bond density between ... -
Non–destructive foliar chlorophyll measurement has the potential to predict crude protein concentration and in vitro ruinal organic matter digestibility in Bracharia decumbens herbage
(ELSEVIER, 2014)Quick and accurate estimation of crude protein (CP) concentration and in vitro ruminal organic matter digestibility (IVOMD) of tropical pastures is critical to determine possible nutrient deficits prior to herbage utilization. ... -
Non–Governmental organisations and rural poverty reduction strategies in Zimbabwe: A case of Binga rural district
(Virtus Interpress, 2015)The purpose of this paper is to evaluate the effectiveness of strategies implemented by Non-governmental organisation (NGOs) for poverty alleviation in Zimbabwe with specific reference to Zimbabwe’s Binga Rural District. ... -
A non–member spouse's entitlement to the member's pension interest
(P.E.R, 2014)It is important that married couples seek legal advice with regard to the assets falling within their joint estate, more particularly their retirement benefits. This article reflects on the entitlement (if any) of non-member ... -
Noodle waste based biorefinery: an approach to address fuel, waste management and sustainability
(Taylor & Francis, 2017)Noodle waste contains significant amounts of starch, lignocellulosic material and oil. Pretreatment involving extraction followed by centrifugation is necessary to separate the oil from the starch and lignocellulosic ... -
Normal- and reverse-phase paper chromatography of leaf extracts of dandelions
(American Chemical Society, 2012)This demonstration describes how normal and reverse phase chromatography can be illustrated using only chromatography paper for the separation of extracts of dandelions. -
Normality of spaces of operators and quasi-lattices
(Springer, 2015)We give an overview of normality and conormality properties of pre-ordered Banach spaces. For pre-ordered Banach spaces X and Y with closed cones we investigate normality of B(X,Y) in terms of normality and conormality of ... -

A normative model for integrating organisations for disaster risk reduction and climate change adaptation within SADC member states
(Emerald, 2017)Purpose Research has demonstrated that governance of disaster risk reduction (DRR) and climate change adaptation (CCA) have evolved largely in isolation from each other – through different conceptual and institutional ... -

The normative sense of the concept of law part II - systematic considerations
(Sabinet, 2013)Modern philosophy left us with an unbridgeable divide between factual reality and the domain of values (normativity). This article first of all analyze modal norms, such as the principle of avoiding what is legally ... -
The North-West University (NWU) Zoology centennial special issue
(Taylor & Francis, 2020)This special issue of African Zoology celebrates 100 years of Zoology as a scientific discipline on the Potchefstroom Campus of the North-West University (NWU), previously known as the Potchefstroom University College ... -
Northern NGOs, southern NGOs and international environmental law: The common interest of humankind is the interest of northern mankind!
(VerLoren van Themaat Centre for Public Law Studies, 2008)States need to address global environmental problems that threaten humankind. Sovereign states, however, seem ill equipped to find solutions to counter global environmental degradation. It is in this regard important to ... -
The Norwegian Missionary Society under apartheid in Durban: attitudes towards the Nationalist Government,the loss of educational endeavours, and the emergence of an autonomous Zulu Lutheran Church
(Church History Society of Soutern Africa (CHSSA)/Unisa, 2011)Active in rural Natal and the Kingdom of Zululand since the middle of the nineteenth century, the Norwegian Missionary Society (NMS) undertook evangelisation and other forms of ministry to urbanised Zulus in and around ...
