In die lig van ontwikkelings in die gesondheidsdienste is dit noodsaaklik dat verpleegadministrateurs bekwame bestuurders moet wees. Die gebied van personeelbestuur is van fundamentele beiang en hiervan is personeelontwikkeling en -onderrig ’n belangrike onderdeel. Enkele gebiede van personeelontwikkeling wat op plaaslike vlak meer aandag behoort te kry, word toegelig met spesifieke verwysing n...

’n Opname oor die houding van geregistreerde verpleegkundiges teenoor hulle beroep is by die Addington-hospitaal, Durban, gemaak. Altesaam 212 geregistreerde verpleegkundiges het op ’n vraelvs reageer. Die belangrikste bevinding is dat verpleegkundiges hulle werk geniet, dat hulle wesenlik sorgsame mense is wat, om humanistiese redes besluit het om te verpleeg. Hulle is egter ontevrede met onto...

Opvoedkundige teorie en praktyk berus op teveel mites wat verwerp behoort te word. Die ware beginsels van leer is dat alle mense ’n natuurlike gawe en potensiaal tot leer en ’n gretige nuuskierigheid oor die wêreld het. Leer sal meer geredelik plaasvind as die leerder voel dat die vak met sy behoeftes verband hou en as hy aktief in die leerproses betrokke is. Die waardevolste les is om te leer ...

We consider the Navier-Stokes equation in a domain with rough boundaries. The small irregularity is modeled by a small amplitude and small wavelength boundary, with typical lengthscale ε ¿ 1. For periodic roughness, it is well-known that the best homogenized (that is regular in ε) boundary condition is of Navier type. Such result still holds for random stationary irregularities, as shown recent...

We investigate the irregularity strength (s(G)) and total vertex irregularity strength (tvs(G)) of circulant graphs Cin(1, 2, . . . , k) and prove that tvs(Cin(1, 2, . . . , k)) = ⌈ n+2k 2k+1 ⌉ , while s(Cin(1, 2, . . . , k)) = ⌈ n+2k−1 2k ⌉ except if either n = 2k + 1 or if k is odd and n ≡ 2k + 1(mod4k), then s(Cin(1, 2, . . . , k)) = ⌈ n+2k−1 2k ⌉ + 1.

Implantable devices capable of several modes of therapy will require differentiation of various ventricular tachyarrhythmias. Three methods of arrhythmia analysis, magnitude-squared coherence, ventricular rate, and irregularity of cycle length were performed for 45 episodes of induced ventricular tachyarrhythmia in 15 patients. Differentiation of monomorphic ventricular tachycardia from polymor...

car body acceleration is an important factor affecting track safety and ride comfort, which are two primary aspects of railway systems. though track level is an important source of wagon body acceleration, no quantitative relation between them is available and the aim of this paper is to propose a method to address this issue. to do so, car body acceleration is determined using a 10 dof simulat...

We compare constrained and unconstrained power law irregularity models for characterizing and interpreting scintillations caused by field-aligned irregularities in the equatorial ionosphere. The unconstrained irregularity model we consider is the two-component power law model described in (Carrano and Rino, Radio Sci., 2016). The constrained irregularity model encapsulates this twocomponent mod...

We investigate a modification of well known irregularity strength of graph, namely the total edge irregularity strength. An edge irregular total k-labeling φ : V ∪E → {1, 2, . . . , k} of a graph G is a labeling of vertices and edges of G in such a way that for any two different edges uv and u′v′ their weights φ(u)+φ(uv)+φ(v) and φ(u′)+φ(u′v′)+φ(v′) are distinct. The total edge irregularity str...

In the cortex, the timing of successive action potentials is highly irregular. The interpretation of this irregularity has led to two divergent views of cortical organization. On the one hand, the irregularity might arise from stochastic forces. If so, the irregular interspike interval reflects a random process and implies that an instantaneous estimate of the spike rate can be obtained by aver...
