introduction: there are general concerns about the hazardous impacts of the cell phones radiation on the human health. in this study, the structural and biochemical changes of the mice kidney were assessed after cell phone exposure in. materials and methods: a total of 40 balb/c mice were randomly divided into the control and experimental groups. the experimental group exposed to cell phone dev...

In this paper, a new model based on the thevenin equivalent circuit for investigating the ultra-saturation phenomenon during the energization of a loaded power transformer is presented and its effect on the differential protection of the transformer is considered. The ultra-saturation phenomenon causes the mal-operation of the power transformer differential protection. So, the description a...

introduction: foot-and-mouth disease (fmd) is a highly contagious and economically devastating viral disease of livestock that is categorized in list a of animal diseases by the world organisation for animal health (oie). vaccination is effective against fmd and the vaccine production centers largely use the industrial ultra-filtration and chromatography in order to remove the cellular proteins...

Sub-Saharan Africa (SSA) is home to two-thirds of the world’s ultra-poor today. This paper offers current thinking on the structural causes of the spatially concentrated, persistent ultrapoverty that has plagued Africa for a generation and some key entry points for facilitating Africans’ escape from persistent ultra-poverty. The increased recognition of persistent ultra-poverty has rekindled lo...

purpose the aims of the present study were to investigate (i) the changes in participation and performance and (ii) the gender difference in triple iron ultra-triathlon (11.4 km swimming, 540 km cycling and 126.6 km running) across years from 1988 to 2011. methods for the cross-sectional data analysis, the association between with overall race times and split times was investigated using simple...

background: the possible role of cochlear function in tinnitus generation is still a matter of debate. to assess the role of outer hair cell dysfunction in tinnitus and its possible relationship with ultra-high frequency (uhf) hearing sensitivity, transient evoked otoacoustic emissions (teoae) and uhf hearing thresholds were investigated in normal hearing individuals with and without tinnitus. ...

regarding many disadvantages of traditional method to produce concentrated yoghurt, several attempts have been done for mechanization of process in industrial scale. using membrane systems especially ultra filtration is one of these methods. in this survey, method to produce direct concentrated yoghurt, fresh milk was concentrated to 19% snf by ultra filtration method then diluted to 13 and 16 ...

objective: to compare the outcome of patients with up to 60% total body surface area (tbsa) thermal burns undergoing ultra-early and early excision and grafting. methods: this historical cohort study was performed in two referral burn centers of shiraz during a 1-year period from 2015 to 2016. we included those patients with thermal burns up to 60% tbsa who underwent ultra-early (48-72 hours) a...

the ultra-nanocrystalline diamond (uncd) was synthesized by the detonation of a high explosive mixture in water confinement. the presence of a diamond phase was revealed by x-ray diffraction (xrd) and transmission electron microscopy (tem). x-ray line broadening (xrlb) was used to evaluate the peak profiles of diamond nanoparticles and their corresponding average crystallite sizes. the micro st...

In this letter, atomically resolved scanning tunneling microscopic (STM) images obtained from monolayer SiO2/Mo(112) are presented. The results are consistent with a previously proposed structural model of isolated [SiO4] units based on vibrational features observed by high-resolution electron energy loss spectroscopy (HREELS) and infrared reflection–absorption spectroscopy (IRAS), and oxygen s...
