electromagnetic field (emf) radiation affects cellular and brain chemistry and function, resulting in deleterious effects such as free radicals formation, impaired dna repair, reduced melatonin and blood brain barrier protection, and defects on learning and memory and other higher brain functions. in this paper the effects of low frequency emf of 50- and 217 hz, ranges often associated with com...
manual citrus harvesting is commonly performing hard, expensive and time consuming. in this study, a factorial experiment with a completely randomized design in three replications was performed to find out the effect of frequency (three levels of 5, 7.5 and 10 hz), vibration time (three levels of 10, 15 and 20 seconds) on harvesting capacity and losses of thomson cultivar of orange. the results...
the efficacious effects of pulsed electromagnetic field (pemf) under the certain field parameters like frequency and the field intensity have been reported for various tissue and molecules. since collagen is found abundantly in most tissue structures, this research was designed to further investigate the effects of extremely low frequency (elf) pemf on the synthesis of the epidermal collagen. t...
This article aims to examine the Ṣūfī interpretation of story prophet Jesus in Qurʾān. The fate Jesus, who came world a miraculous way, resulted similar way. fact that verses Qur’an mention Jews wanting kill him (as well as other verses) do not state what his ultimate was has been focus much discussion. interpretations made by Ṣūfīs, put forward different method Islamic tafsīr tradition terms t...
Introduction: Access to modern methods for increasing the percentage of in vitro human and animal mature oocytes can be useful in the treatment of some forms of human infertility as well as proliferation of many domestic and wild animals which generation is endangered. Effect of low- frequency electromagnetic fields on in vitro growth and maturation of mouse oocytes is recently considered as a ...
