International control need

When mitosis has been completed, the cell requires signals in the form of growth factors to direct towards a new roimd of division. The signals become effective in the first two-thirds of Gi phase. In this time window, the cell is programmed to begin a new cell cycle or to enter Go phase. After a particular point, the restriction point R, no further signals are needed to continue the cell cycle. The cell cycle apparatus is self-contained from this point onwards. S, G2 and M phase occur without external control. The cell cycle may still be halted after crossing the restriction point, however, if the cell detects, via internal control mechanisms or checkpoints, that defects have occurred in the correct course of the phases. [Pg.406]

Although it is the responsibility of an excipient user to qualify their excipient suppliers, that burden is shared with the distributor as well. A pharmaceutical distributor must provide the user with the assurance that the excipients supplied are unadulterated, have not been tampered with, and are free from contamination. To ensure this, a distributor must have warehouse and internal controls in place, comply with current regulatory standards, and should be an active NACD member. Trace-ability of ingredients is another critical need that must be met by pharmaceutical distributors. This can be achieved by providing the manufacturer s original packaging, documentation, and manufacturing site address, confirmed by the manufacturer. [Pg.425]

The controls required to keep the internal reflux flow of the column constant (a) and the controls needed to eliminate the effect of accumulator lag in controlling the external reflux to a column (b). [Pg.249]

A Digi-Sense digital thermometer was used. The internal temperature needs to be monitored, and the additions should be slow enough to avoid significant exotherms. The checkers found that temperature control is the major factor influencing the outcome of the reaction. The initial procedure was submitted as double scale i.e. 11 g (56.2 mmol) (-)-bomyl acetate]. However, the checkers found temperature control on full scale to be difficult, resulting in incomplete reaction and/or over-reduction of the bomyl acetate. The checkers found that the procedure is reliably reproducible on half scale (5.5 g (-)-bomyl acetate). [Pg.82]

Stressing therefore the need for continued systematic and progressive efforts to reduce nuclear weapons globally, with the ultimate goal of eliminating those weapons, and of general and complete disarmament under strict and effective international control. [Pg.643]

Decisions regarding the choice of a specific amplification test for the detection of CT and GC should not be based solely on the cost of reagents. Other key factors to consider include test performance characteristics, such as diagnostic sensitivity and specificity, and whether the test has been cleared for urine and swab specunens in both symptomatic and asymptomatic individuals. Ideally the test should include an internal control, particularly if a crude lysate is used in the assay. Other factors to consider are degree of automation, ease of use, work flow issues, and space and equipment needs. [Pg.1565]

While there are no specific provisions requiring the industry to perform internal prescription of norms (the need for this activity simply follows from the fact that the legally binding safety norms are not precise), there are several provisions requiring the industry to establish a system for internal control. [Pg.128]

Because of the internally controlled mass transfer, drying times for atmospheric freeze-drying are longer than for the vacuum freeze-drying. The difference in drying time increases with particle size (thickness). Thus, for 5-mm-thick particles, about 2 hours are needed to reduce the moisture content from 4 kg/kg to 2 kg/kg in the vacuum process, whereas 6 hours are required... [Pg.307]

Specification Model. This is an abstract representation of the externally observable properties of the software. It defines what the software needs to do, but not how it does it. It does not define any software design details, such as internal data structures, internal data flow or internal control flow. A specification model may be used to express software high-level requirements. It may not be used to express software architecture or software low-level requirements. [Pg.307]
