Winter interruptions

In winter, lightning is not a severe problem, but snow and ice can collect on power lines and tear them down. This results in interruptions that last for a number of days because thousands of kilometers of wire must be replaced. Winter interruptions are less common than summer interruptions, but when they occur they often last longer because the damage is greater and the repair crews have a difficult time working in ice and snow. 

Although winter wheat is grown on more land than any other crop in England and Wales, it is not usually grown continuously, because of problems from pests and diseases. Break crops are grown to interrupt the build-up of these problems, so we need to look at the behaviour of nitrogen under these and other crops, but much less information is available than for winter wheat. 

In such diverse and sophisticated gas-using economies, security of supply and the efficient employment of producing assets depend upon an extensive network of pipelines that interconnect regions with diverse climates and diverse consumption patterns winter-peaking and summer-peaking demand that is climate-sensitive, business cycle-sensitive, and price-sensitive customers who place a high premium on continuity of supply, and those who are relatively insensitive to risk of interruption. These parties depend to a different degree, and place... 

Interruptible contract. There is an obligation for the user to provide an alternative standby fuel to be used at the request of the gas supplier. The maximum period of interruption is one of the conditions agreed in the contract. The advantage to the user is that he or she can obtain a more favorable gas price. The advantage to the supplier is that at times of peak demand, such as a cold winter, he can balance supply and demand without investing in excessive storage capacity. 

After Hardegger received his degree of Diplom Ingenieur Che-miker in the Autumn of 1938, he joined Ruzicka s sex-hormone research-team. His doctoral thesis comprised two parts the first dealt with the elimination products of anhydro-oxyprogesterone in human urine, and the second, with the preparation and reactions of A4-17,20-oxypregnen-3-one. Despite lengthy interruptions in his research, caused by active duty during the war years, he finished his thesis in the winter of 1941, three years after he started it. 

Winter et al. [41] could demonstrate that the intra-operative treatment of retinal detachments with PFCLs, followed by an exchange to intraocular gas, resulted in total coating of the retinal surface with the fatal effect of complete sealing, creating an interruption of essential transretinal exchange processes. Equivalent scenarios have to be taken into consideration in the situation of a completely filled eye or if the droplets of an endotamponade media show a non-spherical shape. 

Probably Klaus s experiments on the residues from platinum ores and on the new metal ruthenium have already been described in the German journals. He sent me his paper in manuscript. You see thereby that he has also prepared colorless salts of iridium with sulfurous acid. The early severe winter in November interrupted the postal communication between Ystad and Stralsund, so that I have not received the German journals for three months (28). 

As the site is snowbound for about six months of each year, the treatment plant was designed to operate unattended for months on end. Unattended operation over short periods was demonstrated, though after the final inspection before winter the wastewater supply from the mine to the treatment plant was interrupted by rupture of the feed pipe under snow loading, which also crushed two sheds at the site. However, a flume packed with crushed limestone to neutralize mine drainage operated continuously through the winter under snowpack. 

An accidental fire interrupted the startup of a U.S. Gulf Coast Plant during a cold winter morning. The plant experienced 100,000 (U.S. 1978) of property damages. All it took to cause such extensive damage was less than 50 gallons (200 liters) of combustible heat transfer fluid. 

The annual mean values of the Wamemunde/Rostock time series of surface air temperature have increased by more than 0.3°C from 8.32°C in 1987 to 8.65°C in 2004 (Fig. 4.27, see also Chapter 5). This continuous and strong rise of the annual mean temperature over the past 20 years was only shortly interrupted in 1996 by the cold European winter of 1995/1996. 

IF DURING RAINY SEASON / WINTER (SNOW) JAM IS SEVERE THAT FULL LINE NEEDS DISMATLING TO REMOVE JAM. THEN INTERRUPTION. MAY BE FOR LONG PERIOD AND IF THERE IS NO ALTERNATE PATH. SEVERITY COULD BE S4.
