Conditional watch

A conditional watch expression causes VBA to enter break mode only when a variable changes in value or when an expression evaluates to True. 

To establish conditional watch expressions, choose Add Watch from the Debug menu and press the appropriate Watch Type button (see Figure 14-22). There are three possibilities, which are indicated by different icons in the Watches pane ... 

The fire department blamed the accident on welders cutting in hazardous areas without a fire watch, highly combustible structural components (fiber-glass-resin), high-density storage of highly flammable and detonable material, spilled ammonium perchlorate about the plant, and high w ind conditions. 

Under cavitating conditions a pump will perform below its head-performance curve at any particular flow rate. Although the pump may operate under cavitation conditions, it will often be noisy because of collapsing vapor bubbles and severe pitting, and erosion of the impeller often results. This damage can become so severe as to completely destroy the impeller and create excessive clearances in the casing. To avoid these problems, the fol-iotving are a few situations to watch ... 

The strippable films deposited from solvents in the cold are much thinner (= 0.05-0.25 mm) than those from the hot-dip materials, and their protective properties are not nearly so good. A possible difficulty which must be watched for is the development of brittleness on ageing and consequent difficulty of stripping. Latex films containing inhibitors such as sodium benzoate have been found to deteriorate under tropical conditions, but may have a use in more temperate climates. 

One method we might use is to cool the melt to incipient nuclei-formatlon. toss in the seed-crystal, and allow the melt to freeze into a single crystal. This is the KYROPOULOS method which we will discuss in detail later. Alas, this method only works for a few systems, notably alkali halides (cubic) and the like. We find that we can use a seed-crystal to grow single crystals, but only if we use it under carefully defined conditions. A modified K5rropoulos method has been used for many years to form single-crystal sapphire up to 13.0 inches in dieimeter. Plates cut from such crystals are used as windows and substrates for all sorts of integrated circuits, as well as watch "crystals". 

Control of exudation depends mainly on the suitable choice of the nitrocellulose used. Some lack of uniformity in this product is certainly desirable. This offers no serious difficulty, although it is necessary to ensure a constant watch on manufacturing processes to see that quality is maintained. In other gelatine explosives, particularly those containing ammonium nitrate, exudation can be induced by slow chemical reaction. The addition of alkalis, for example, can liberate ammonia which in turn can react with nitrocellulose and cause it to lose its power of binding nitroglycerine. Such effects are accelerated at high temperatures and under wet conditions and it is usual practice to test all explosives under such adverse conditions before they are put on the market. 

For similar human reasons, we should document every single oscilloscope plot carefully the moment we capture it (assuming it seems meaningful of course). Write down the input and output voltages, currents, specific applied conditions (i.e., power-up into short circuit), the state of the other pins, and so on. Don t forget to keep close track of what each channel represented (or later, just watch yourself suffer Hey look, by moving the pole-zero pair apart, I now have negligible overshoot at start-up. Oops, that must have been the Enable... 

For a socially living individual it is of high relevance to be aware of the emotional state of one s conspecifics. It is a fairly well-known phenomenon that animals of different species react to odour emitted by another animal which is under stressful conditions. This led several researchers to the question of whether emotional state in humans can influence their body odour. This possibility was first tested by Chen and Haviland-Jones (2000), who asked their subjects to wear armpit pads while watching 13 min excerpts from a comedy or a fearful movie. Most of them watched both excerpts. Subsequently three and six choice tests were presented to raters who were instructed to pick the sample that smelled of people when they are happy or... 

Investigate the influence of temperature TR by running at slightly higher and lower temperatures. Watch changes in all variables listed in Exercise 1. See if safe conditions result, such that TMRad is always greater than 24 h. 

We have attempted to find conditions which will allow us to watch the species build up, to isolate it kinetically, and to observe its reactions directly. That does not imply that the intermediate is unreactive. The remarkable feature of the intermediate in your rhenium system is the apparently facile oxygen atom transfer. 

It was tme. For about seventy feet in all directions there was a thick fog, only a few feet deep, hugging the ground. Even as we watched, the condition thickened and spread outward, becoming finally a general fog over the whole area. We had come from depthless, clear night sky to dense fog in a few minutes. I was frankly amazed. Dennis was the first to offer an explanation, with a certainty that seemed as puzzling as the thing itself... 

This method works for every urine test, every time (provided that some conditions are met). You simply give them clean urine (not yours). This works very well if you are not supervised. If you are going to be supervised, try to talk them out of it. Someone told me they were going to be monitored, and they said I don t want you to fuckin watch me piss So the supervisor waited outside probably with his/her ear to the door to listen for opening containers. Members in active duty are often watched as the urine flows from source to destination (but substitution will even work on this test, as you will find out). Abbie Hoffman, author of Stealing This Urine Test, suggested leaving a few drops of urine on the seat or on your shoe for as an added measure of authenticity. ... 

Traditionally the most popular of the phosphorescent pigments are based on activated zinc sulfide, especially by copper, which glow green. These find their outlets in clock, watch and instrument dials, which are required to be visible in temporary, poor lighting conditions. They are also widely used in novelty items such as plastic toys and in sporting goods, for example as fish floats. Some typical commercial materials are shown in Table 3.2. ...
