WORKING CONDITION

The RCCA s (32 to 52 assemblies in the core), regulate the neutron flux in the reactor, and are used for emergency shutdown of the reactor activity. In normal working conditions, the RCCA s are suspended above the fuel elements. 

Benefits resulting from better control of glass melting ate lower fuel consumption, better glass quality, more efficient production time, and better pollution control. Fewer operators are needed and working conditions are better. 

Hydrogen chloride in air is an irritant, severely affecting the eye and the respiratory tract. The inflammation of the upper respiratory tract can cause edema and spasm of the larynx. The vapor in the air, normally absorbed by the upper respiratory mucous membranes, is lethal at concentrations of over 0.1% in air, when exposed for a few minutes. HCl is detectable by odor at 1—5 ppm level and becomes objectionable at 5—10 ppm. The maximum concentration that can be tolerated for an hour is about 0.01% which, even at these levels, causes severe throat irritation. The maximum allowable concentration under normal working conditions has been set at 5 ppm. 

Naphthaleneamine. 1-Naphthylamine or a-naphth5iamine/7i5 -i2- can be made from 1-nitronaphthalene by reduction with iron—dilute HCl, or by catalytic hydrogenation it is purified by distillation and the content of 2-naphthylamine can be reduced as low as 8—10 ppm. Electroreduction of 1-nitronaphthalene to 1-naphthylamine using titania—titanium composite electrode has been described (43). Photoinduced reduction of 1-nitronaphthalene on semiconductor (eg, anatase) particles produces 1-naphthylamine in 77% yield (44). 1-Naphthylamine/7J4-J2-. can also be prepared by treating 1-naphthol with NH in the presence of a catalyst at elevated temperature. The sanitary working conditions are improved by gas-phase reaction at...

The composition data should always be appHed to in-service performance (64,65) in order to properly evaluate the behavior of the asphaltic binder under tme working conditions. 

Additions of cadmium (0.05—1.3%) to copper raise the recrystallization temperature and improve the mechanical properties, especially in cold-worked conditions, with relatively Htde reduction in conductivity. Copper containing 0.07% cadmium is used in automotive cooling fins, heavy-duty radiators, motor commutators, and electric terminals. 

Most wrought alloys are provided in conditions that have been strengthened by various amounts of cold work or heat treatment. Cold worked tempers are the result of cold rolling or drawing by prescribed amounts of plastic deformation from the annealed condition. Alloys that respond to strengthening by heat treatment are referred to as precipitation or age hardenable. Cold worked conditions can also be thermally treated at relatively low temperatures to affect a slight decrease in strength (stress rehef annealed) to benefit other properties, such as corrosion resistance and formabiUty. 

Base-plate waxes are formulated for specific uses or working conditions into types 1,11, and 111. Consequentiy, the flow requirements differ. Type 1 waxes are soft waxes for building contours and veneers, type 11 waxes are medium waxes used for pattern production in the mouth in temperate weather, and type 111 waxes are hard waxes used for production in the mouth in hot weather. At 37°C, type 1 waxes have a 45—85% flow at 45°C, type 11 waxes have a 50—90% flow and type 111 waxes have a 5—50% flow. 

Evaluation of the Dusting Properties of Powder (or Other Solid Dyes). A number of methods exist to test this increasingly important behavior because of the greater awareness of working conditions and good industrial practice present today. 

Biosensors ai e widely used to the detection of hazardous contaminants in foodstuffs, soil and fresh waters. Due to high sensitivity, simple design, low cost and real-time measurement mode biosensors ai e considered as an alternative to conventional analytical techniques, e.g. GC or HPLC. Although the sensitivity and selectivity of contaminant detection is mainly determined by a biological component, i.e. enzyme or antibodies, the biosensor performance can be efficiently controlled by the optimization of its assembly and working conditions. In this report, the prospects to the improvement of pesticide detection with cholinesterase sensors based on modified screen-printed electrodes are summarized. The following opportunities for the controlled improvement of analytical characteristics of anticholinesterase pesticides ai e discussed ... 

The working conditions of the immunosensor (enzyme and antigen concentrations, dilutions of the antibodies, pH of the buffer solution) were found. The cholinesterase immobilized demonstrated the maximum catalytic activity in phosphate buffer solution with pH 8.0. The analytical chai acteristics of the sensor - the interval of the working concentrations and detection limit - have been obtained. The proposed approach of immunoassay made possible to detect 5T0 mg/ml of the bacterial antigen. 

Turnover rate is a key indicator of how an employer values their employees. Employees who have a career path, are rewarded for good performance, and provide contributions to the success of their employer are less likely to leave. On the other hand, companies with high turnover rates may not provide such good working conditions and the resulting turnover results in employees who may not have much experience. 

Due to excessive starting and braking heat losses it is not advisable to switch an induction motor ON and OFF frequently. The number of starts and stops a motor is capable of performing will depend upon its working conditions such as type of switching, braking and load demand etc. and can be determined from... 

Figure 8.12 shows the arc of contact, i.e. the contact angle, the belt would make with the pulley. As for a motor a belt is also subject to unfavourable operating conditions that require deratings depending upon the working conditions, arc of contact and the length of the belt selected as noted below ... 

All these standards have since been adopted by the member countries as their national standards, fully or in slightly modified forms, to suit their own requirements and working conditions. These standards define and clarify the quality norms and aim at in-house quality disciplines, to automatically and continually produce a product, provide a service or programme to the stipulated specifications, quality norms and customer needs. They guarantee a product or service with a minimum quality. The envisaged quality systems thus aim at a work culture that pervades all those involved in different key activities or processes, to achieve the desired goal through carefully evolved systems. 

For meticulous protection, therefore, it is advisable to use a motor protection relay for large LT and all HT motors. The following motor details and working conditions are essential to know before making i proper selection of a protective scheme ... 

To maintain reproducible excitation conditions in the glow discharge source, the working conditions (e. g. argon pressure, dc-current or rf-power) are carefully controlled. 

The emission yield, Ra, defined as the radiation of the spectral line, k, of an element, i, emitted per unit sputtered mass must be determined independently for each spectral line. The quantities g, and Ry are derived from a variety of different standard bulk samples with different sputtering rates. In practice, both sputtering rates and excitation probability are influenced by the working conditions of the discharge. Systematic variation of the discharge voltage, L/g, and current, I, leads to the empirical intensity expression [4.185] ...

The quality of bonding and hence the properties and the performanee of the wood-based panels and beams are determined by three main parameters (1) the wood, espeeially the wood surface, including the interface between the wood surface and the bond line (2) the adhesive (3) the working conditions and process parameters. 

For the production of wood-based panels various adhesives are in use like aminoplastic resins (UF, MU(P)F), phenolic resins (PF) or isocyanate (PMDI). The proper choice of the adhesive depends on the required properties of the wood-based panels, on the working conditions during the production as well as often on the costs for the adhesive system this not only means the net price of the adhesive but the overall costs of the gluing system including glue spread factor.
