Pelvic muscle contractions during sexual response can be monitored conveniently by the anal probe method described. Eleven young adult male subjects were each recorded for three sessions of masturbation to orgasm. Electrical signals from an anal pressure probe were automatically digitized by computer. Orgasmic contractions were easily distinguished from voluntary contractions by the steadily in...

in order to evaluate the effect of different irrigation intervals on some morphophysiological traits of sesame (sesamum indicum l.), an experiment was conducted under greenhouse conditions during 2009. the experiment was based on a randomized completely design with three replications. treatments included four irrigation intervals with 4, 8, 12 and16 days intervals and two ecotypes of sesame (ka...

Regular bursts of electric field radiation pulses produced by three multiple-stroke cloud-to-ground discharges recorded in 1991 at the NASA Kennedy Space Center are analyzed. The bursts are similar in the number of pulses per burst and inter-pulse intervals to the “multiple burst” component (so-called component H) of the standard lightning environment for the design and testing of aerospace veh...

rangelands have been composed of different plant species that emergence of phenological stages in every one of them will be influenced by environmental and genetic factors. in order to exploit the time and achieve acceptable performance in each plant species, it is necessary that the emergence of biological phenomena are recorded and studied. the objective of the present study is to survey the ...

We present an empirical model of Arabidopsis (Arabidopsis thaliana), intended as a framework for quantitative understanding of plant development. The model simulates and realistically visualizes development of aerial parts of the plant from seedling to maturity. It integrates thousands of measurements, taken from several plants at frequent time intervals. These data are used to infer growth cur...

We say a string has a cadence if a certain character is repeated at regular intervals, possibly with intervening occurrences of that character. We call the cadence anchored if the first interval must be the same length as the others. We give a sub-quadratic algorithm for determining whether a string has any cadence consisting of at least three occurrences of a character, and a nearly linear alg...

in this research the effects of mycorrhizal symbiosis and irrigation intervals on growth indices and grain yield of two sorghum cultivars was studied. field experiment was laid out as a split plot factorial based on randomized complete block design with three replications. irrigation intervals as main factor in three levels (7, 14 and 21days) and factorial combination of two sorghum cultivars (...

background: when family planning programmes offer a wide variety of contraceptives, contraceptive prevalence would be higher overall. objective: to determine the acceptability of cyclofem© and to evaluate its side effects and continuation rate in iran. materials and methods: an introductory study of cyclofem© was conducted in seven districts of kerman province, the largest province of iran, in ...
