Maintain the water temperature between 25°C and 30°C. Many laboratories maintain their colonies at 28°C or 28.5°C. Measure and record the temperature daily. It is recommended to maintain room air temperature at approximately the same temperature or slightly less to minimize condensation. 

This procedure can be utilized to determine whether heavy fuel wax crystal modifiers will lose their performance properties after long-term storage at fluctuating temperatures. Daily heating and overnight cooling may interfere with the ability of some wax crystal modifiers to maintain their performance properties in some residual oils and crude oils. This loss of performance is frequently termed pour point reversion. The British Admiralty Pour Point Test can be utilized to help predict these reversion tendencies.

The reduction and decorrelation of weather records were considered for a heating season when air pollutants concentrations are particularly high. In decorrelation calculations the weather records for heating seasons (December, January and February) for the last 20 years were used. Each record (daily average) consists of eight weather components, namely mean daily air temperature, daily precipitation totals, mean daily wind direction and velocity, cloudiness, pressure, relative air humidity and sun duration. On the basis of the PCA procedure it was found that four components in the decorrelated system are sufficient to describe the weather vector. An error resulting from the size reduction did not exceed 0.25 % in this case. The method was described by Kaminski et al. [2]. 

This expression is known as the vapor lock index (VLI) or the front-end volatility index (EEVI). The value of n for U.S. cars is generally reported as 9 when RVP is in kPa (0.13 when pressure is in psi) (23). The maximum level of VLI is set by month and by region according to the ninetieth percentile daily maximum temperature. 

Vehicle volatihty requirements are a strong function of ambient temperatures. ASTM has defined five volatihty classes based on expected minimum and maximum daily temperatures. These classes and their ranges are shown in Table 3. Each month, each state is assigned a volatihty class, depending on its temperature history. Table 3 also shows the ASTM volatihty specifications for each class. 

Iodized Salt. Iodized table salt has been used to provide supplemental iodine to the U.S. population since 1924, when producers, in cooperation with the Michigan State Medical Society (24), began a voluntary program of salt iodization in Michigan that ultimately led to the elimination of iodine deficiency in the United States. More than 50% of the table salt sold in the United States is iodized. Potassium iodide in table salt at levels of 0.006% to 0.01% KI is one of two sources of iodine for food-grade salt approved by the U.S. Food and Dmg Administration. The other, cuprous iodide, is not used by U.S. salt producers. Iodine may be added to a food so that the daily intake does not exceed 225 p.g for adults and children over four years of age. Potassium iodide is unstable under conditions of extreme moisture and temperature, particularly in an acid environment. Sodium carbonate or sodium bicarbonate is added to increase alkalinity, and sodium thiosulfate or dextrose is added to stabilize potassium iodide. Without a stabilizer, potassium iodide is oxidized to iodine and lost by volatilization from the product. Potassium iodate, far more stable than potassium iodide, is widely used in other parts of the world, but is not approved for use in the United States. 

Diethylcarbama2ine [98-89-1/ is a pipera2ine derivative which is given daily as a prophylactic for canine heartworm disease Dirofilaria immitis) or as a therapeutic for roundworms. D. immitis is transmitted only by mosquitoes, and therefore the period of administration varies geographically, depending on temperatures and humidity which regulate the mosquito life cycle. 

For extended, noncyclic exposures, it can be assumed that the entire piece teaches the temperature of the heating medium and is, therefore, subject to permanent strength losses throughout the piece, regardless of size and mode of stress application. Because dry wood is a good insulator, it often does not teach the daily extremes in temperature of the air around it in ordinary constmction thus, estimates of long-term effects should be based on the actual wood temperatures experienced by critical stmctural parts. 

The best quahty to be found may be a temperature, a temperature program, a concentration, a conversion, a yield of preferred product, a cycle period for a batch reaction, a daily production level, a land of reactor, a size for a reactor, an arrangement of reactor elements, provisions for heat transfer, profit or cost, and so on—a maximum or minimum of some of these factors. Among the constraints that may be imposed on the process are temperature range, pressure range, corrosiveness, waste disposal, and others. 

The downtime is 1 h per batch. Find the temperature at which the daily production is a maximum. 

While process design and equipment specification are usually performed prior to the implementation of the process, optimization of operating conditions is carried out monthly, weekly, daily, hourly, or even eveiy minute. Optimization of plant operations determines the set points for each unit at the temperatures, pressures, and flow rates that are the best in some sense. For example, the selection of the percentage of excess air in a process heater is quite critical and involves a balance on the fuel-air ratio to assure complete combustion and at the same time make the maximum use of the Heating potential of the fuel. Typical day-to-day optimization in a plant minimizes steam consumption or cooling water consumption, optimizes the reflux ratio in a distillation column, or allocates raw materials on an economic basis [Latour, Hydro Proc., 58(6), 73, 1979, and Hydro. Proc., 58(7), 219, 1979].
