Common heart arrhythmia monitors are limited to the electrical activity of the ventricles. Severe cardiac malfunctions exhibit typical defects of atrioventricular conduction which often can be efficiently treated with medicine or electrotherapy. The method described here enables the detection of complete atrioventricular blocks and may be used for the improvement of arrhythmia monitoring.

The alternation of stationary periods and periods of movement may be an important feature of an animal's search tactic. Unambiguously differentiating stops and moves may be difficult, especially from highly resolved digitized pathways, but their identification may be essential for understanding an animal's searching behavior. In this paper, we describe a method for defining stops in search pathways. A computer program that identifies the stop-and-go movement patterns from digitized pathway data is available upon request from the authors.

The impacts on overall water supply resulting from different water management strategies for conjunctive use of surface and ground waters were studied for a 90-mile section of the South Platte River. A computer simulation study was conducted using data for the 10 years between 1952 and 1961. A drought period in the early '50s is included. The management strategies considered included: 1) lining some of the canals to improve conveyance efficiency; 2) improving water use efficiency on the farm; 3) pumping with relaxed restrictions; and, 4) a combination of all these strategies. The study indicates that the most effective strategy by far to alleviate the serious consequences of a drought on irrigated agriculture is to fully use the ground water reservoir capacity of the stream-aquifer system. Under increased pumping the stream and the aquifer quickly reach a new equilibrium and after two years there is no indication of a continued mining condition in the aquifer. This strategy is not only effective in the short term but also safe in the long *** impacts on overall water supply resulting from different water management strategies for conjunctive use of surface and ground waters were studied for a 90-mile section of the South Platte River.

Earth-resistance measurement of large electrodes, carried out by the fall-of-potential method, can involve difficulties and errors. To eliminate these disadvantages, the authors have developed a systematic analysis of different grounding systems buried in nonhomogeneous soils. The analysis is made by using a computer program based both on Maxwell's subareas method and on the method of electric images; the soil is represented by a two-layer equivalent model with known parameters. This paper shows the computer program theory in full. Moreover, systematic analysis provides numerous curves allowing accurate measurements of the earth resistance of large grounding systems with often-used shape when the auxiliary current electrode is located near the grounding system under test. Finally, the authors show that the given curves can also be used for earth-resistance measurement of those systems whose shapes are different. In conclusion, this paper supports the contents of IEEE Standard 81-1983 and extends its application range.

Non-uniform distribution of absorbed dose in cross-section of any polymeric pipe is caused by non-uniform thickness of polymer layer penetrated by unidirectional electron beam. The special computer program was created for a prompt estimation of dose non-uniformity in pipes subjected to an irradiation by 1-10 MeV electron beam. Irrespective of electron beam energy, the local doses absorbed in the bulk of a material can be calculated on the basis of the universal correlations offered in the work. Incomplete deceleration of electrons in shallow layers of a polymer was taken into account. Possibilities for wide variation of pipe sizes, polymer properties and irradiation modes were provided by the algorithm. Both the unilateral and multilateral irradiation can be simulated.

Instrumental neutron activation analysis (INAA) using rabbit irradiation system at ETRR-2 reactor was utilized to analyze some elements namely Na, Mg, Al, Cl, V, Mn, In, and Br in four different crude petroleum samples from different oil fields in the Suez-Gulf region of Egypt. The INAA was performed by four different standardization methods. Namely absolute, single comparator based on effective cross section concept, single comparator based on k(O,Au) factors, and that based on k(0,ic) factors defined versus any suitable internal comparator method. A FORTRAN computer program was written to calculate the extracted concentrations by these methods. A reasonable agreement between the obtained results was noticed. (C) 2010 Elsevier Ltd.

A combined radioimmunoassay for glucagon and insulin in biological fluids is presented. It is based on the use of 131I-glucagon and 125I-insulin tracers and a charcoal-dextran separation procedure. Standard curves, sample determinations and recovery studies gave comparable results whether in the combined or individual assay for glucagon and insulin. The combined assay, especially if supported by a decoding and calculating computer program, offers the advantages that it requires a smaller volume of the material to be sampled, is more economical and less timeconsuming.
