First signs

There are numerous reasons why seals fail prematurely. The origin of the failure can reside in the pumping system, in the pump operation, or the maintenance shop, the storeroom, or even before the seal arrived into the plant. The first sign of failure normally is lit]uid on the floor. 

Al Preparation of 7-Hydroxy-4,8-Dimethy/coumarin Chilled ethyl acetoacetate (157 ml, 1.20 mols) followed by 2-methyl-resorcinol (130 g, 1.04 mols) was dissolved in well-stirred concentrated sulfuric acid (600 ml) at such a rate as to keep the temperature below 10°C (ice bath). The stirred solution was allowed to warm gradually and after 3 hours was added to water (ca 8 liters) with mechanical stirring. The product was collected, washed twice with water, and dried at 70° to 80°C until the first sign of darkening. Yield 191.3 g (95.4%). Recrystallization from aqueous ethanol gave 7-hydroxy-4,8-dimethylcoumarin as colorless needles, MP 260.5° to 261°C. In dilute sodium hydroxide, the compound gives a yellow solution which exhibits blue fluorescence. 

In permeation measurements the first signs of hydrogen diffusing through 1 mm steel membranes can be observed in a few minutes. The practical measurement of diffusion parameters tends to be rather unreproducibie. 

In most GRPs debonding can occur after even a small number of cycles, even at modest levels. If the material is translucent, the buildup of fatigue damage can be observed. The first signs (for example, with glass-fiber TS polyester) are that the material becomes opaque each time the load is applied. Subsequently, the opacity becomes permanent and more pronounced, as can occur in... 

Closed-loop systems should lose very little water, perhaps only 5 to 10% of the system volume per year. In practice, however, losses often tend to be much higher than this, perhaps due to unforeseen maintenance work that necessitates a system to be partially drained. A typical loss is more likely to be 50% of the system volume per season. This obviously causes problems with regard to maintaining adequate chemical treatment reserves for effective deposit and corrosion control. In fact, often the first sign that a closed-loop system is losing water is when a periodic test is undertaken and the result indicates a reduced level or complete lack of treatment reserve.

Demonstrate that the first signing of a continuous session uses all electronic signature components. 

When to stop a fermentation is a very complex decision and several factors have to be taken into account. Quite often a manufacturer will find it appropriate to harvest shortly after the first signs of a faltering in the efficiency of conversion of the most costly raw material (the carbon source, e.g. glucose) into penicillin. 

The PAMIR study predicts fine chemicals as one of the first fields where commercialization of micro-reactor technology will start [241, 337]. The small quantities, sometimes only in the kilogram range, and the large margins make the substitution of existing processes by micro reactors attractive. Currently, we can see the first signs of this, e.g. the work of Merck, Siemens-Axiva, Clariant and others. 

Ascites is the accumulation of fluid in the peritoneal space and is often one of the first signs of decompensated liver disease. Ascites is the most common complication of cirrhosis and portends a dire prognosis.14...

The longer it persists the more difficult it is to remove. So it is important to act immediately there are signs of algal growth. That first sign is most probably the greenish colour appearing in the pool water. 

At the first sign of a cold, it can be mixed with hyssop (Hyssopus officinalis), peppermint (Mentha piperita) and yarrow (.Achillea millefolium).
