The hazards of chemicals are commonly detected in the workplace first, because exposure levels there are higher than in the general environment. In addition, the exposed population is well known, which allows early detection of the association between deleterious health effects and the exposure. The toxic effects of some chemicals, such as mercury compounds and soot, have been known already for centuries. Already at the end of the eighteenth century, small boys who were employed to climb up the inside of chimneys to clean them suffered from a cancer of the scrotum due to exposure to soot. This was the first occupational cancer ever identified. In the viscose industry, exposure to carbon disulfide was already known to cause psychoses among exposed workers during the nineteenth century. As late as the 1970s, vinyl chloride was found to induce angiosarcoma of the liver, a tumor that was practically unknown in ocher instances. ... 

Figure 9.11 Several minimum energy paths for O2 dissociation on PtsCo) 11) (labeled by respective initial states), generating ML of atomic O, compared with equilibrium and 2% compressed Pt(lll). The points on each path are the images or states used to discretize the path with the climbing-image nudged elastic band method. The zero of the energy axis corresponds to an O2 molecule and the respective clean surfaces at infinite separation. The points located on the right vertical axis represent atomic O at ML.

Even if there are already many suitable nest sites, a bird box may encourage a normally shy species of bird to stay in your yard. Bird boxes can be made of untreated wood or "woodcrete" (a concrete/sawdust composition). The latter version is useful if your garden has predatory squirrels or even woodpeckers with a taste for young birds. All bird boxes should be positioned so that you can access them easily to clean them out in fall, which is important. Put your bird box on a sheltered wall or tree trunk, well away from predators, rain, and direct sunlight. Cats can climb up and reach into boxes from all sorts of unlikely angles, as can gray squirrels, so position the box carefully. 

Cutting off a small branch Never attempt to cut large limbs off a tree yourself, or climb a tree to prune it. But if you need to remove a small, low branch, first equip yourself with a garden pruning saw, as shown below. Make an undercut about 1 in (2.5 cm) from the trunk of the tree first below left), to stop the bark from tearing should the branch fall, then cut cleanly down center) to the undercut. Do not cut flush to the trunk leaving the branch collar intact far right) helps the tree recover from the wound much more quickly. 

Thus we would expect water to climb up the walls of a clean (i.e. water-wetting) glass vessel for a few millimetres but not more, and we would expect a sessile water droplet to reach a height of several mm on a hydrophobic surface, before the droplet surface is flattened by gravitational forces. The curved liquid border at the perimeter of a liquid surface or film is called the Plateau border after the French scientist who studied liquid shapes after the onset of blindness, following his personal experiments on the effects of sunlight on the human eye. 

It was claimed by the Russians that the use of prossal nik increased the life of the gun (Ref 1), but according to US sources (Ref 2), the use of bore lubrication decreased the muzzle velocity. When oil was used as a lubricant, the muzzle velocity of the first round was practically the same as in the gun previously cleaned and dried, but velocities of the 2nd, 3rd, etc rounds were appreciably lower. After firing a number of rounds (number not stated) the muzzle velocity started to climb back to that obtained when firing was conducted in a gun not previously lubricated (Ref 2)... 

Brazzein is a sweet protein that was isolated from the fruit of the West African climbing plant Oubli (Pentadiplandra brazzeana Baillon). Along with pentadin, which was discovered in 1989, brazzein is the second sweet protein that was discovered in this fruit. Like other natural sweet proteins such as monellin and thaumatin, it is highly sweet. On a weight basis, brazzein is 500 times sweeter than sucrose when compared to 10% sucrose solution and 2000 times sweeter when compared to 2% sucrose solution. Its sweet perception is more similar to that of sucrose than that of thaumatin, and it presents a clean sweet taste with a lingering aftertaste. Brazzein is stable over a broad pH range from 2.5 to 8 and is heat stable at 80 °C for 4h.84... 

The first test with cellulose (Experiment 1.05) used no steam flow. Because the evolved volatile matter cracked on the vycor walls depositing an opaque, black material thereon, the wall temperature of the reactor rapidly climbed to temperatures above 1000°C. Gasification data is presented in Table 1 for the 0.54 g of cellulose fed into the reactor during the test. Subsequent, brief exposure of the reactor to the solar flux with steam (but no biomass) flow cleaned the reactor s walls nicely. 

The evaluation of functional capacity should focus on the presence and severity of symptoms the patient experiences during activities of daily living and how those symptoms affect these activities. Questions directed toward the patient s ability to perform specific activities may be more informative than general questions about what symptoms the patient may be experiencing. For example, ask patients if they can participate in exercise, climb stairs, get dressed without stopping, check the mail, or clean the house. Another important component of assessment of functional capacity is to ask patients what activities they would like to do but are now unable to perform. 

People must leam how to use ladders correctly. They need to know how to select them for the job, and how to place, use, carry and store them. Ladders are not intended for transporting materials. Carrying an object while climbing a ladder violates the three-point support principle because one cannot grasp the ladder at all times. A slip is very likely to lead to a fall. Hoist materials and tools to the upper work level. Users should clean their shoes and ladder steps or rungs to reduce the chances of slipping.
