Subject contraction

In the region with pesticide contamination where subjects contracted viral hepatitis A, the pre-jaundice period was 4.2 days (in the control area, 5.1), the jaundice period lasted 32 days (22.4 in the control area), the liver enlarged more than in the control area and took longer to return to normal size, there was a larger number of patients who also had an enlarged spleen, there was more frequent damage to the nervous and cardiovascular systems (1.5-2 times higher than in the control area), mixed syndrome was observed more often (45% of the time, compared to 12.6% in the control area), and the illness was more frequently serious.

They are classified apart in this text because their use differs from that of petroleum solvents they are used as raw materials for petrochemicals, particularly as feeds to steam crackers. Naphthas are thus industrial intermediates and not consumer products. Consequently, naphthas are not subject to governmental specifications, but only to commercial specifications that are re-negotiated for each contract. Nevertheless, naphthas are in a relatively homogeneous class and represent a large enough tonnage so that the best known properties to be highlighted here. 

The end product specification of a process may be defined by a customer (e.g. gas quality), by transport requirements (e.g. pipeline corrosion protection), or by storage considerations (e.g. pour point). Product specifications normally do not change, and one may be expected to deliver within narrow tolerances, though specification can be subject to negotiation with the customer, for example In gas contracts. 

In discussing Fig. 4.1 we noted that the apparent location of Tg is dependent on the time allowed for the specific volume measurements. Volume contractions occur for a long time below Tg The lower the temperature, the longer it takes to reach an equilibrium volume. It is the equilibrium volume which should be used in the representation summarized by Fig. 4.15. In actual practice, what is often done is to allow a convenient and standardized time between changing the temperature and reading the volume. Instead of directly tackling the rate of collapse of free volume, we shall approach this subject empirically, using a property which we have previously described in terms of free volume, namely, viscosity. 

Specifications for raw cane sugar are set by purchase contracts. There are no international specifications, although the Codex JUimentarius is composing a draft specification. Because raw sugar is not sold as a food product in the United States (it is transported in bulk, like grain or coal), it is not subject to food regulations. Purchase contracts outside the United States are generady based only on pol U.S. contracts are discussed in the Hterature (6). 

Vacuum must be considered. It is nearly always possible that the contents of a vessel might contract or condense sufficiently to subject it to an internal vacuum. If the vessel cannot withstand the vacuum, it must have vacuum-breaking valves. 

Quite often problems arise when instruments for normal seiwice are subjected to low temperature use. Since some metals become brittle at low temperatures, the instrument hteraUy falls apart. Elastomeric gaskets and seals contract faster with decreasing temperatures than the surrounding metal parts, and the seal often is lost. Even hermetically sealed instruments can develop pin holes or small cracks to permit ciyogenic liqmds to enter these cases with time. Warming the instrument causes the trapped hquid to vaporize, sometimes generating excessive gas pressure and failure of the case.

In a small mechanism, a polypropylene spring is subjected to a fixed extension of 10 mm. What is the initial force in the spring and what pull will it exert after one week. The length of the spring is 30 mm, its diameter is 10 mm and there are 10 coils. The design strain and creep contraction ratio for the polypropylene may be taken as 2% and 0.4 respectively. 

If the spring is subjected to a 50% overload for 1 day, estimate the percentage increase in the extension over the normal 1 day extension. The shear stress in the material is given by 16 WR/d. Use the creep curves supplied and assume a value of 0.4 for the lateral contraction ratio.

Ensuring that the policy is relevant to the expectations and needs of the organization s customers is a little more difficult. Companies need to predict what their customer expectations and needs are (now a requirement in clause 4.1.4 under Business plans). They may be beyond what they specify in contracts although they may in fact be identical to such specifications. For companies to create satisfied customers they not only need to meet requirements specified by the customer but meet national and international legislation and have consideration for the needs and expectations of society. As explained in Part 1 Chapter 1 on Quality characteristics, customers are not only the buyers but comprise several other interested parties. You need to provide a means of determining what the customer expectations and needs are and then subject the written quality policy to a review against those expectations and needs to determine if there is any conflict. As part of your business planning procedure you should indicate how you determine your customer s current and future needs and expectations. 

An adequately documented requirement would be a written contract, schedule of work, and/or specification. However simple the requirement, it is wise to have it documented in case of a dispute later. The document needs to carry an identity and if subject to change, an issue status. In the simple case this is the serial numbered invoice and in more complicated transactions, it will be a multi-page contract with official contract number, date, and signatures of both parties. 

Consider an angle-ply laminate composed of orthotropic laminae that are symmetrically arranged about the middle surface as shown in Figure 4-48. Because of the symmetry of both material properties and geometry, there is no coupling between bending and extension. That is, the laminate in Figure 4-48 can be subjected to and will only extend in the x-direction and contract in the y- and z-directions, but will not bend. 

Smooth muscle contractions are subject to the actions of hormones and related agents. As shown in Figure 17.32, binding of the hormone epinephrine to smooth muscle receptors activates an intracellular adenylyl cyclase reaction that produces cyclic AMP (cAMP). The cAMP serves to activate a protein kinase that phosphorylates the myosin light chain kinase. The phosphorylated MLCK has a lower affinity for the Ca -calmodulin complex and thus is physiologically inactive. Reversal of this inactivation occurs via myosin light chain kinase phosphatase. 

The Environmental Protection Agency (EPA) and other federal, state and local authorities govern security of supply in relation to quantity for surface and groundwater by the granting of an abstraction license. The license limits the total daily quantity and the rate at which the waters may be abstracted, taking account of the natural resource and the needs of other abstractors. Metered water supply is subject to contract with the water companies, who may impose quantity and draw-off rate limitations. The limitations imposed by the license or contract may influence plant location.
