Testing frequency programs

I hypothesised (Baker and Beilis 1995 Baker 1996) that the within-population frequency distribution of testes size reflects a balanced polymorphism. In this hypothesis, men with larger testes were programmed to spend less time with partners, ejaculate often, and expose their sperm more often to sperm competition. Men with smaller testes were programmed to invest more in mate guarding and only infrequently to expose their sperm to competition. Between the two extremes, the intermediate men were programmed to pursue a more mixed strategy. 

A well-designed stability program meets all regulatory requirements and attains its objectives with minimal expenditure of resources. It provides all necessary data in a form that can be easily interpreted and evaluated, and distinguishes between analytical variability and instability. It specifies a testing frequency, which will provide early detection of instability and support the desired expiration-dating period. 

It takes years to develop and fine-tune a prooftest program. Time is required to identify all of the instrument loops that need to be included, and more time is needed to systematically collect or develop data sheets containing basic operational information for each device or loop. During the development stage, test methods need to be defined, and the appropriate personnel responsible for testing must be identified and trained. Finally, test frequencies must be decided. 

Equipment used to process, store, or handle highly hazardous chemicals must be designed constructed, installed and maintained to minimize the risk of release. A systematic, scheduled, test and maintenance program is preferred over "breakdown" maintenance " that could compromise safety. Elements of a mechanical integrity program include 1) identification and categorization of equipment and instrumentation, 2) documentation of manufacturer data on mean time to failure, 3 ) test and inspection frequencies, 4) maintenance procedures, 5) training of maintenance personnel, 6) test criteria, and 7) documentation of test and inspection results. 

Also, the particular boiler plant water-steam chemistries must be reviewed and interpreted at regular intervals. The specifics and complexity of this work depend on the type of boiler plant involved and the respective chemical treatment programs employed. The frequency of testing may range from hourly to perhaps monthly, again depending on the type of boiler operation. 

These analysers exist in many forms but are essentially relatively small bench instruments, which use small test pieces and can be programmed to measure damping and dynamic moduli as a function of temperature and frequency. Apart from their importance for measuring the dynamic properties where these are relevant to service, they allow the generation of a large quantity of data over ranges of temperature and frequency extremely efficiently. Hence, they can be used effectively to obtain modulus even if the application is not dynamic. Another valuable use is to obtain glass transition temperatures. 

Improve documentation of relief valve inspection and pop tests. Annual testing of relief valves is recommended until a valve has a history of good pop tests. Then the frequency can be slowly extended. (Program established by March 2002)... 

The treatment of HP has become increasingly difficult due to the frequency of antibiotic resistance and recurrence after successful treatment. In Peru, the recurrence rate of the infection is as high as 73% even after successful eradication. In this instance, recurrence is not attributed to antibiotic resistance but to re-infection of patients. In the United States, resistant HP is also of concern. The Helicobacter pylori Antimicrobial Resistance Monitoring Program (HARP) is a multicenter US network that tracks HP patterns of resistance. In 2004, HARP reported that 34% of 347 HP isolates tested were resistant to one or more antibiotics commonly used to treat HP infections.In the US, most antibiotic resistance is associated with metronidazole and clarithromycin, both standard treatment options for HP. Thus, antibiotic resistance and high re-infection rates strongly argue for the development of new therapeutic modalities to prevent and treat HP infections worldwide.
