摘要:
Borehole conditions can be determined using distributed measurement data. Real time data measurements can be taken from sensors distributed along the length of a drill string to assess various conditions or properties of the borehole. In particular, the distributed data can be used for example, to track the progress of a chemical pill or also track the location of different types of borehole fluids, and also to determine the hole size or volume of the borehole.

Systems, methods, non-transitory computer-readable media storing computer program instructions for causing a computer device to implement methods, and the like utilize weather information from one or a variety of locations to estimate costs for providing weather-dependent work, and to provide financial controls for weather-dependent work allegedly performed. One method includes utilizing historical weather information relating to performance of weather-dependent work at a work location to generate an estimate of an anticipated frequency with which weather-dependent work will be necessary, utilizing information to estimate an anticipated cost per incident for performing weather-dependent work at the selected work location, and using such information at a plurality of locations to generate an aggregate bid for performing weather-dependent work at the locations. Weather information is also used to audit weather-dependent work allegedly performed at the work locations to provide financial controls to the aggregated weather-dependent work in compliance with law and regulation.

Compounds of the formula ##STR1## wherein R is H, halo, C.sub.1-4 alkyl, C.sub.1-4 alkoxy, 3,4-methylenedioxy, CF.sub.3, NO.sub.2, NH.sub.2, N(C.sub.1-4 alkyl).sub.2, CN, OH, --S(C.sub.1-4 alkyl) or --SO.sub.2 (C.sub.1-4 alkyl); R.sub.1 and R.sub.2 are independently each H or C.sub.1-4 alkyl or taken together with the attached N atom are morpholino, piperidino, pyrrolidino, piperazino, or N-- C.sub.1-4 -alkyl piperazino; and, when R is halo, C.sub.1-4 alkyl or C.sub.1-4 alkoxy, x is 0-3 and, otherwise, is 0 or 1;or a pharmaceutically acceptable salt thereof with an acid or for the compounds wherein R.sub.1 and R.sub.2 are both not H, a quaternary ammonium salt thereof with a C.sub.1-4 alkyl halidehave valuable antiviral activity, e.g., for treatment of infections caused by a herpes virus.
摘要:
Methods of determining borehole conditions using distributed measurement data are disclosed herein. The disclosed methods utilize real time data measurements taken from sensors distributed along the length of a drill string to assess various conditions or properties of the borehole. The disclosed methods of processing or using distributed measurement data have not been described before. In particular, the distributed data may be used for example, to track the progress of a chemical pill or also track the location of different types of borehole fluids, and also to determine the hole size or volume of the borehole.

This invention relates to 1-aryl-3-pyridinyl-2-propene-1-ones, the use of these compounds as calcium uptake inhibitors in leukocytes and thrombocytes, and pharmaceutical compositions containing these compounds as active ingredients, and the process of their preparation.
摘要:
The present invention relates to certain novel polyamine compounds of the formula: ##STR1## wherein Z is a saturated (C.sub.2 -C.sub.6) alkylene moiety, each R group independently is hydrogen, methyl, ethyl, or n-propyl with the provisos that both R groups cannot be hydrogen and that R is hydrogen or methyl when Z is a branched chain alkylene; or a pharmaceutically acceptable acid addition salt thereof.
摘要:
Certain chalcone derivatives are reported to inhibit the polymerization of tubulin to form microtubules and are therefore antimitotic agents which can be used to control the growth of tumor tissue and can be used as antigout agents.
