Stiffening joints

In addition to the obvious health risks, extreme cold can decrease efficiency and increase the likelih(X)d of work-related accidents, because it affects the performance of both mental and physical tasks. Manual tasks are impaired because the sensitivity and dexterity of fingers are reduced in the cold, notes the The Canadian Centre for Occupational Health Safety. At even lower temperatures, the cold affects the deeper muscles, resulting in reduced muscular strength and stiffened Joints. ... 

Chilly, damp weather stiffens joints In studying the relationship of weather to arthritic pain in weight-bearing joints, preliminary data show a significant correlation between joint pain and changes in weather. 

Overexposure to cold causes discomfort and a variety of health problems. Cold stress impairs performance of both manual and complex mental tasks. Sensitivity and dexterity of fingers lessen in cold. At lower temperatures still, cold affects deeper muscles, resulting in reduced muscular strength and stiffened joints. Mental alermess is reduced due to cold-related discomfort. For all these reasons accidents are more likely to occur in very cold working conditions. 

Structural baghouses are limited to very large baghouses. All structural components are fabricated as separate panels with formed flanges. The panels are bolted or welded in the field. These flanged joints serve as stiffeners to the hoppers, plenum, tube sheets, and baghouse enclosures.

Thin to large wall Designing around TP problems is the joint responsibility of the product and mold designers. For example, one way to handle the problem of thin to large area walls is by the inclusion of long ribs into the product in the direction of plastic flow. These ribs are not a functional requirement of the product but they act as auxiliary runners attached to the product to facilitate plastic flow in difficult to fill areas. In some instances the ribs may be used as a surface decoration like a corrugation or they may be on the concealed side of the product where they are stiffeners. 

From the standpoint of long life and freedom from maintenance, dished, hemispherical and cone bottoms are the best for cylindrical tanks, and are the designs of necessity if a vessel is to be "prestressed" (see Chapter 47), or if there is a desire or necessity to eliminate expansion joints. Flat bottoms, unless provided with properly designed expansion joints, will heave upward with brick growth. In addition, adequate and frequent stiffening is required if flexing and... 

The elbow joint is a comparatively weak part of the body and a forceful blow can dislocate it. Grasp your opponent s wrist or forearm and pull it behind him, stiffening his whole arm (fig. 29). As... 

Courts that apply the rule only to fact probabilities essentially seek a yes-or-no belief in a >50% fact probability. By contrast, traditional courts that apply the rule only to belief probabilities seek a >50% belief in a yes-or-no fact. In toxic tort/occupational disease claims where both fact probability and belief probability are issues, there are at least two other approaches. Courts could apply the more-likely than-not standard jointly, reducing alleged fact probability by a factor reflecting the jury s doubt about its truth. By contrast, the rule could be applied sequentially to require only a > 50% belief in a fact probability which itself may barely exceed the >50% threshold. It is important to see that joint application stiffens the causation burden-of-produc-tion/burden-of-persuasion, while sequential application substantially lessens the causation production/ persuasion requirements. The point here is that, regardless of approach, a court that deals with causal indeterminacy characteristic of toxic tort/occupational disease claims should be explicit about what it is doing, especially if defendant s culpability of conduct or duty to prevent risk is factored into determination of the causation issue. 

A 4-year-old boy presents to the physician s office with coarse facies, short stature, stiffening of the joints, and mental retardation. Both parents, a 10-year-old sister, and an 8-year old brother all appear unaffected. The patient s mother is pregnant. She had a brother who died at 15 years of age with similar findings that seemed to worsen with age. She also has a nephew (her sister s son) who exhibits similar features. Based on the probable mode ot inheritance, the risk that her fetus is affected is...

As depicted in Pigs. 9.11 and 9.12, the BM investigations reveal broad, mechanically stiffened interphases in the EP adjacent to all the metal films. The v level of these interphases is almost the same but the position of the peak maximum and the half-width at half-maximum (HWHM) depend on the kind of metal. The EP interphases on aluminum and copper are almost twice as wide as on magnesium and gold. In contrast to the polished metals considered above, the adhesion strength is good enough to maintain the EP-metal joint in the mechanical test. The samples fail between the metal film and the silicon wafer.
