koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

How Large Does n Have to Be for Z and t Intervals?
No full textStudents invariably ask the question "How large does n have to be for Z and t intervals to give appropriate coverage probabilities?" In this article we review the role of p fi 1 (X)= p n, where p fi 1 (X) is the skewness coefficient of the random sample, in the answer to this question. We also comment on the opposite effect that p fi 1 (X) has on the behavior of t intervals compared to Z intervals. Finally, we suggest a simple exercise for determining rules of thumb for n that result in appropriate confidence interval coverage. KEY WORDS: Confidence interval; Convergence to normality; Central Limit Theorem; Edgeworth expansion; Kurtosis; Skewness; t statistic.

Lidskii's Theorem Via Nonsmooth Analysis
No full textLidskii's theorem on eigenvalue perturbation is proved via a nonsmooth mean value theorem. 1 Research partially supported by the Natural Sciences and Engineering Research Council of Canada. The author thanks the School of Operations Research and Industrial Engineering at Cornell University, where this work was completed. One of the central tools for studying perturbation theory for the eigenvalues of symmetric matrices is Lidskii's theorem. This states that any matrices Z and Y in S n , the Euclidean space of n \Theta n real symmetric matrices (with trace inner product), satisfy (Z + Y ) \Gamma (Z) OE (Y ); (1) where (Z) 2 R n is the column vector of eigenvalues of Z written by multiplicity and in decreasing order. The symbol OE denotes majorization: u OE v for vectors u and v in R n means u 2 conv fPv : P 2 P n g; where P n is the group of n \Theta n permutation matrices and `conv ' denotes convex hull. A standard separation argument (see [6], for example) shows this..
Effect of gravity on clustering patterns and inertial particles attractors
No full textIn this contribution we study the clustering of inertial particles using a periodic kinematic simulation. The systematic Lagrangian tracking of particles makes it possible to identify the particles’ clustering patterns for different values of particle’s inertia and drift velocity. The different cases are characterised by different pairs of Stokes number St and drift parameter ϒ. For the present study 0 ≤ St ≤ 1 and 0 ≤ ϒ ≤ 2. The main focus is to identify and then quantify the clustering attractor - when it exists - that is the set of points in the physical space where the particles settle when time goes to infinity. Depending on gravity or drift effect and inertia values, the Lagrangian attractor can have different dimensions varying from the initial three-dimensional space to two-dimensional layers and one-dimensional attractors that can be shifted from an horizontal to a vertical position
Where Are Ennahdha’s Competitors?
No full textEnnahdha, a political party of Muslim democrats, is a major force in Tunisia's emergence as a democracy. The author explains why a viable Islamic rival has not appeared and explores the implications for Tunisia should one emerge.

Accreditation where accreditation is due
No full textA laboratory with fully developed and accredited quality systems is highly desirable.\ud
In some cases it is mandatory. This is evidenced by the concerns raised when\ud
certain medical testing laboratories have not maintained appropriate standards to\ud
retain their accreditation with NATA. Whether or not third party accreditation is\ud
mandated, good laboratory practice based on sustainable systems is required.\ud
\ud
Internationally accepted standard ISO/IEC 17025 provides specific guidelines for\ud
operating a laboratory that may be accredited. To what extent should a university\ud
laboratory implement this standard? Is NATA accreditation necessary? As staffing\ud
and funding reduce is it possible to maintain high standard quality systems that are in\ud
reality truly required if assurance of results is due? Accreditation may be required\ud
where accreditation is due but is credit given by the institutions for the resources\ud
required to get there or stay there? These issues are considered in relation to\ud
university and commercial laboratories and specific case points are raised from\ud
experience with NATA accreditation in the School of Civil Engineering, QUT
Stably stratified shear-produced turbulence and large-scalewaves in a lid driven cavity
No full textWe study experimentally stably stratified sheared turbulence and large-scale flows and waves in a lid driven cavity with a non-zero vertical mean temperature gradient. Geometrical properties of the large-scale vortex (e.g., its size and form) and the level of small-scale turbulence inside the vortex are controlled by the buoyancy (i.e., by the temperature stratification). The observed velocity fluctuations are produced by the shear of the large-scale vortex. At larger stratification obtained in our experiments, the strong turbulence region is located at the upper part of the cavity where the large scale vortex exists. In this region the Brunt-Väisälä frequency is small and increases in the direction outside the large-scale vortex. This is the reason of that the large-scale internal gravity waves are observed in the regions outside the large-scale vortex. We found these waves by analyzing the non instantaneous correlation functions of the temperature and velocity fields. The observed large-scale waves are nonlinear because the frequency of the waves determined from the temperature field measurements is two times smaller than that obtained from the velocity field measurements. The measured intensity of the waves is of the order of the level of the temperature turbulent fluctuations
Some z<sub>n-1</sub> terraces from z<sub>n</sub> power-sequences, n being an odd prime power
No full textA terrace for Zm is a particular type of sequence formed from the m elements of Zm. For m
odd, many procedures are available for constructing power-sequence terraces for Zm; each terrace of this
sort may be partitioned into segments, of which one contains merely the zero element of Zm, whereas
every other segment is either a sequence of successive powers of an element of Zm or such a sequence
multiplied throughout by a constant. We now refine this idea to show that, for m=n−1, where n is an odd prime power, there are many ways in which power-sequences in Zn can be used to arrange the elements of Zn \ {0} in a sequence of distinct entries i, 1 ≤ i ≤ m, usually in two or more segments, which becomes a terrace for Zm when interpreted modulo m instead of modulo n. Our constructions provide terraces for Zn-1 for all prime powers n satisfying 0 < n < 300 except for n = 125, 127 and 257
