rates have been observed to depend on aspect ratio ~ depth/width ! rather than the absolute feature size. 1 Several mechanisms have been invoked to explain the ‘‘rule’’ of aspect-ratio-dependent etching ~ ARDE ! ‚ but no general theory has emerged that captures the variety of seemingly conflicting experimental observations reported in the literature. 1‚2 For example‚ while an ion-neutral synergy model with pure neutral flux shadowing appears to be con- sistent with a wealth of

Answers to Questions Activity 1: Simulating Dialysis (Simple Diffusion) (pp. 2–4) 9. All solutes except albumin are able to diffuse into the right beaker. Using distilled water in the right beaker and either the 100 MWCO or 200 MWCO membrane will remove urea from the left beaker and leave albumin If the left beaker contains NaCl‚ urea‚ and albumin‚ you can selectively remove urea by dispensing a concentration of NaCl into the right beaker equivalent to that in the left beaker and by using

Calculating Tank Volume Saving time‚ increasing accuracy By Dan Jones‚ Ph.D.‚ P.E. C alculating fluid volume in a horizontal or vertical cylindrical or elliptical tank can be complicated‚ depending on fluid height and the shape of the heads (ends) of a horizontal tank or the bottom of a vertical tank. Exact equations now are available for several commonly encountered tank shapes. These equations can be used to make rapid and accurate fluid-volume calculations. All equations are rigorous‚

on the results by varying different variables such as selling price‚ variables cost‚ etc. This altering of variables to determine the net effect of changing original estimates is called sensitivity analysis. Using the computerized application of CVP‚ managers can study various combinations of ‘changes in selling price‚ fixed and variables and assess their effect on profit’ (SWTAFE‚ 2012). Based on the CVP analysis of the three business plans provided by Digital Ltd‚ I would like to recommend the

INTRODUCTION Absence is the failure of a worker to report for work when he is scheduled to work. A worker is to be considered as scheduled to work when the employer has work available for him and the worker is aware of it. A worker is to be treated as absent for purpose of this absenteeism. Statistics even when he does not turn up for work after obtaining prior permission any worker who reports for duty even for a part of the day or shift should not be‚ counted among absentees. The statistics

am investigating the relationship between surface area and the volume of a model cactus and to determine whether this relationship affects the loss of water. We used oasis blocks‚ an absorbant material used by florists as a substitute for a cactus‚ that would soak up the water‚ and thus ideally show the percentage water loss by weighing the before and after evaporation weights. Independent Variable The independent variable is the total surface area for each size of the blocks and I think this

Physical development can have an emotional effect on a child because if the child does something good then they will get praised with will have a positive effect on the child which will make them happy. However‚ the child’s social development could be affected because if the child has a physical disability‚ e.g. the child is in a wheelchair‚ then the child would find it hard

The purpose of this lab was to observe the rate of osmosis and diffusion‚ as well as the effect of molecular size of the particles on this rate. Part I of the lab was a demonstration of osmosis and diffusion‚ that dealt with raisins in different liquid environments‚ each with a different concentration of sugar. Part IV of the lab was using the same idea as the demonstration‚ by putting objects in different concentrations of a substance; in this case elodea leaves in salt water. In both cases‚ the
