Leg Room

Don t get too granular in your thinking. For example, if you re listing the features of a first class airplane seat, some characteristics might be ample leg room or reclines to a bed. This leaves more opportunity for creativity than specifying that the seat has 10 inches more leg room than a coach class seat, or that the seat reclines to a 160 degree angle. 

Size differences The workplace allows for all size differences between people in terms of clearance, reach, eye height, leg room, etc. 1 2 3 4 5... 

Some of these problems are relatively simple in nature, and simple to cure. In one local school where evidence was gathered recently, a new Acorn Rise PC system had been set up on a purpose-built trolley. The VDU was positioned well above normal head height, even for a tall Year 6 child. This meant that the pupils had to look upwards at quite a steep angle to use the system comfortably. In reality, pupils were observed standing to nse the computer, so that the monitor was at a suitable height. This then caused problems with control of the mouse and keyboard on the desk-top, which was situated much lower down. Sustained use of such a system would be likely to induce spinal problems. The solution here would be to move the system off the trolley and place it on a table of the correct height. In another school, the computer was set up on a cupboard with no leg room for the pupils. This meant that they had to sit twisted sideways to use it, forcing them to adopt bad posture. The solution here would be similar. 

This will generally be tr-ue as we proceed to look at other alkanes as the number of carbon atoms increases, so does the boiling point. All the alkanes with four car bons or less are gases at room temperature and atmospheric pressure. With the highest boiling point of the three, propane is the easiest one to liquefy. We are all faniliar- with propane tanks. These are steel containers in which a propane-rich mixture of hydrocar bons called liquefied petroleum gas (LEG) is maintained in a liquid state under high pressure as a convenient clean-burning fuel. 

Cabinets come in a variety of units to suit individual needs. These are then bolted together to make benches. Any combination of drawers, cupboards, and knee-hole units is possible. Some fume hoods come complete with their own base cabinets. Where desirable, desk-height units can be integrated into the system. All units come with legs which can be acijusted for an uneven floor. Standard installation leaves room behind the counters or along the middle of peninsulas for utilities. After the cabinets are installed, counter tops are put in place and bench-mounted fume hoods added. 

A 56-year-old man presents to the emergency room with complaints of right lower leg pain and redness. Examining his leg, you notice that he has erythema and edema extending from his ankle to proximal tibia. The area feels warm. On questioning, the patient states that the redness started approximately 2 days ago. He has felt feverish over the previous 48 hours but did not check his temperature. He has had no other symptoms. He states that he bumped his shin on the bed frame last week and sustained a bruise but no apparent breaks in the skin. His vital signs at the clinic reveal a temperature of 38.3°C, pulse 102 beats per minute, blood pressure 11 0/72 mm Hg, and respiratory rate 20 breaths per minute. The physician diagnoses this patient with cellulitis. 

The synthesis of [Ircp Cl(bpy-cd)]Cl, where bpy-cd is a /3-cyclo-dextrin attached at the 6 position to a bpy ligand, is detailed.138 The complexes [Ircp (diimine)X]+, X = C1, H, diimine = bpy, phen, are active catalysts for the light-driven water-gas-shift reaction.139 The hydride complexes luminesce at 77 K and room temperature, whereas the chloride complexes do not.140 The three-legged piano-stool arrangement of the ligands in [Ircp (bpy)Cl]+ and [Ircp (4,4 -COOFl-bpy)Cl]+ is confirmed by X-ray crystallography.141,142 Further mechanistic studies on the catalytic cycle shown in reaction Scheme 11 indicate that Cl- is substituted by CO and the rate-determining step involves loss of C02 and H+ to leave the Ir1 species, which readily binds Fl+ to yield the lrIH hydride species.143... 

Appears to be sleeping - moving extremities spasmodically. HR 124, BP 110/5003 00 HR 120 I feel very tired and loss of coordination also. I can t keep my legs still. I feel like I want to go, go, go. To latrine at 03 05. Voided 260 cc. To Audiology at 03 10. Back to padded room at 03 13. Walked with assistance. 

Effect of Oxygen on the Reaction of Syringyl Alcohol with Alkali. Ethanolic solutions of syringyl alcohol (0.0545M in 5 ml.) and sodium hydroxide (0.0923M in 5 ml.) were placed separately in each leg of an inverted Y-tube. After the system was exhaustively evacuated, the solutions were mixed and allowed to react at room temperature. For comparison, an identical experiment was conducted in the presence of air. 

Back in the atelier, I went straight to the fireplace and lit more lamps to make the room bright. Every shadow held a lurking demon. I needed sunlight, lots and lots of noon sun. Tomorrow was going to be foggy. I sat cross-legged on the hearth rug, hunched close to the warmth. 

Meanwhile in America, laughing gas was appearing in traveling medicine shows and carnivals. Gardner Quincy Colton, a former medical student, presided over one of these nitrous oxide demonstrations in Hartford, Connecticut, in December of 1844. One of the audience volunteers who had just inhaled the gas injured his leg without feeling any pain. In the audience was dentist Horace Wells, who took note of this and immediately seized on the idea that nitrous oxide might be a powerful anesthetic in the operating room. 

An ACME operating table has four legs. Each leg is square, closed on the end and measures 0.10 m x 0.10 m. If the table weighs 1200 N and the patient on the table weighs 800 N, what is the total pressure exerted on the operating room floor ...
