Longitudinal distributions of the photospheric magnetic field studied on the basis of National Solar Observatory (Kitt Peak) data (1976 – 2003) displayed two opposite patterns during different parts of the 11-year solar cycle. Heliolongitudinal distributions differed for the ascending phase and the maximum of the solar cycle on the one hand, and for the descending phase and the minimum on the o...

with the introduction of communicative language teaching, a large number of studies have concerned with students’ oral participation in language classrooms. although the importance of classroom participation is evident, some language learners are unwilling to engage in oral activities. this passivity and unwillingness to participate in language classroom discussions is known as “reticence”. rev...

Mid-range periodicities in solar flare occurrence have been analyzed with new methods for cycles 19–23. During cycle 23, periodicities of 129-d and 33.5-d were in operation. Five episodes of high activity occurred periodically with the 129-d period. The 33.5-d periodicity mainly operated for energetic flares. Results for cycles 19–21 are generally in agreement with previous analyses. For cycle ...

An influence of solar irradiance variations on Earth’s surface climate has been repeatedly suggested, based on correlations between solar variability and meteorological variables1. Specifically, weaker westerly winds have been observed in winters with a less active sun, for example at the minimum phase of the 11-year sunspot cycle2–4. With some possible exceptions5,6, it has proved difficult fo...

Background: Ultrasound is preferred as first imaging modality in the study of the female pelvis. In this article, we have tried to mention 8 points that each midwife or nurse needs to know for planning the time of sonography and analysis of findings. Results: During the menstrual cycle, all pelvic organs are influenced by cyclic changes. Thus, pathologic conditions of pelvis need to be well ass...

background: in general, measurements of solar ultraviolet (uv) radiation are related to horizontal surfaces. while the hu­mans walking and standing outdoors expose to the natural solar uv radiation, their eyes, cheeks, extremities, trunks, or many other anatomical sites are close to vertical plane and random orient to different directions. in this study, we character­ized the diurnal variations...
