Analysis on incomplete could lead to biased estimation when using standard statistical procedure since it ignores the missing observations.The disadvantage of ignoring missing data is that the researcher might not have enough data to conduct an analysis.The main objective of the study is to compare the performance between listwise deletion (LD), me
A compact and high-resolution optical orbital angular momentum (OAM) sorter is proposed and demonstrated.The sorter comprises a quadratic fan-out mapper and a dual-phase corrector positioned in the pupil plane and the Fourier plane, respectively.The optical system is greatly simplified compared to previous demonstrations of OAM sorting, and the per
Defining ecologically relevant upper temperature limits of species is important in the context of environmental change.The approach used in the present paper estimates the relationship between rates of temperature change and upper temperature limits for survival in order to evaluate the maximum Avocado Oil long-term survival temperature (Ts).This n
Mentoring is intended to guide student teachers towards pedagogical decision-making Laminate Tops within the complexity of the classroom.In this article we focus on the mathematics mentoring practices of 1 primary school teacher at a university-affiliated teaching school in Johannesburg.The teacher had many years of experience and had undergone som
This paper considers the possibility of using vortex devices for interphase interaction while carrying out various physical and chemical processes ball-stretchers in the chemical, food, gas production, construction and other industries.In the processes of mass transfer, one or several distributed components perform the transition from one phase to
