Fall—same level (FS). An employee can trip on a shoe lace, or slip on ice, hydraulic fluid, oil, brake fluid, or any other chemical. All examples involve falls at the same level that the employee is working.

After nitration is finished the apparatus is slowly emptied at the rate of about 150 1. of acid per hour. At the same time cold water supplied by a rubber pipe is allowed to flow at the same rate onto the surface of the aluminium plate so as to maintain the same level of liquid in the nitrator. During this operation acid is displaced by water that also mixes with the acid retained in the guncotton. The boundary between the two liquids falls in the vessel at a rate of 2.5 mm/min. 

Compressors are also served by high-liquid-level trips in their upstream knockout drums. These high-liquid-level trips work in the same way as the low-level boiler trips discussed above, except that the mercuroid switch is activated by a rising, rather than a falling, liquid level so as to protect the compressor from a slug of liquid. 

Other evidence which has been adduced to support the significance of neurogenic factors in renal hypertension is the observation that the arterial pressures of normal and renal hypertensive dogs and rabbits were reduced to essentially the same level after complete destruction of the central nervous system (18,19). However, interpretation of the results obtained with this drastic procedure is difficult. Other workers have observed a sharp fall in pressure when the spinal cord was destroyed below C5 (the level of the fifth cervical vertebra) in renal hypertensive dogs, but the pressures returned to hypertensive levels as the acute effects of the operation wore off (32). Other experiments involving elimination of the central connections of the sympathetics by cervical cord section in the region of C7... 

The phenomenon of electro-osmosis can be studied by using a U-tube [fig. (9)] in which a plug of moist clay (a negative sol) is fixed. The two limbs of the tube are filled with water to the same level. The platinum electrodes are dipped in water and potential applied. It is observed that water level rises on the cathode side, while it falls on the anode side. This motion of the medium towards the negative electrode, shows that the charge on the medium is positive. Similarly, for a positively charged sol, electro-osmosis will occur in the reverse direction. 

In each study, the dynamics revealed concentrations over time that are influenced by the presence or absence of a feed-forward or preadaption state in the system. The concentration of A steadily diminishes as successive concentrations of B, C, and D rise and fall at the same levels. The concentration of E rises at the end of the run, eventually becoming the only ingredient in the system. The concentration of D is ca. 0.25 in a nonanticipatory model. In contrast, with an anticipatory or feed-forward step in the system there is created an additional amount of enzyme specific for substrate D (enzyme, 2,4) that is available at a future time to catalyze the conversion of D to E. This anticipatory attribute creates a property of the system in which the concentration of ingredient D is not allowed to accumulate to its normal level. In contrast, the concentration of D in an anticipatory model is approximately 0.13, about half the D concentrations for the nonanticipatory models. The concentration of B therefore serves as a predictor of the concentration of D at a later time. 

A person may fall down on the floor at the same level by slipping while working or walking briskly. A person may fall because of the collapse of a piece of equipment, ladder, structural support, or hoist on which he is working. Preventive measures should be adopted while working at these places. 

Thus if we consider a wide U-tube containing water in which initially the water level is higher in one arm than in the other. The level in this arm falls, passes through the equilibrium position, and then rises in the other arm to nearly the same level the reverse process then occurs. If we were able to reduce friction and viscosity to zero, we should obtain in the limit a reversible change. 

While determining the liquid height, it is better to measure with a falling (or receding) meniscus, so that the liquid level is initially raised above its equilibrium value by a slight suction above the capillary tube, and then left to equilibrate. On the other hand, two-armed capillary tubes, connected with a cross tube above the liquid level, are also used to ensure that the pressure in both arms of the glass apparatus is the same. An interesting modification of the capillary rise method is to measure the pressure, AP, that is required to force the meniscus down until it is on the same level as the plane surface of liquid outside the capillary tube. This method is useful to compare the surface tension of water and its dilute solutions. 

Another electronic method is based on the use of a manometer liquid such a.s butyl glycol that has been made feebly conducting by the. addition of a small quantity of a salt such as sodium nitrite. The current passing at 6—8 V need be only about 10 A with an electronic relay it can be made to switch a current of 10—15 A at 220 V. The controller functions as follows. In one limb of a U-shaped vessel, maintained at a constant temperature, the required control vacuum is established (Fig. 374b). If the same pressure is present in the apparatus connected to the other limb, the contact liquid is at the same level in the two limbs. An increase in pressure in the apparatus causes the liquid in the limb joined to it to fall contact is then made in the other, and an electronic relay starts the pump, which continues to run until contact... 

In diabetic rats, the HMGR activity at any time of the day is very low and the circadian rise and fall in activity is absent [36]. Treatment of a diabetic animal with insulin restores the reductase activity to about the same level as in a control animal assayed at the same time of day, and daily injections of a slowly-released form of insulin restores the circadian rhythm of cholesterol biosynthesis to normal. 

It is important to keep in mind that chemical weapons and explosives are designed to kill people. Even in the worst-case scenario in industrial site remediation—such as Love Canal in Niagara Falls, New York— the contaminants are by-products and often do not rise to the same level...
