Přehlédl jsem odkaz na konci článku tady na ekolistu - k původní práci se dá dostat, o teplotě píšou toto: Fractions A (control group) were incubated under similar conditions without the computer. Incubation of Spermatozoa Under Laptop For each sperm sample, one of the dishes (fraction B) was incubated at room temperature under a laptop computer (Toshiba Satellite M305D-S4829) connected to the internet wirelessly (Wi-Fi, frequency 2.4 GHz defined by IEEE 802.11b). To induce the greatest possible effect, the laptop worked actively (uploading and downloading information) throughout the period of exposure (24). To maximize the likelihood of observing deleterious effects the distance between the computer and each specimen was kept constant at 3 cm. This distance was the estimated distance between the computers resting on the lap and the testis/epididymis (Fig. 1B and C). The duration of exposure was 4 hours (Fig. 1A). The temperature under the laptop was kept at 25C during the incubation time by an air conditioning system. The temperature on each medium drop was thoroughly controlled by an IVF Thermometer (Research Instruments) and recorded every 5 minutes. Unexposed aliquots (fraction A) were used as control and kept under identical temperature and conditions in another room away from any computers or electronic devices. After the incubation period, sperm vitality, motility, and DNA fragmentation were determined on each aliquot. Což vypadá rozumě, asi to bude stát za přečtení celé... | |
