Nanostructured hematite thin films are doped with zirconium successfully and also modified by introducing CNT using sol-gel method for their implementation as photo-electrode in photo-electrochemical (PEC) cell for hydrogen generation. XRD, UV-visible spectroscopy and PEC study techniques are used to characterize the thin films. The PEC responses of thin films are improved by introducing carbon...

the aim of this investigation is to compare the effect of applying two transcutaneous electrical nerve stimulation (tens) current with different frequencies (2 hz & 100 hz) on hoffmann reflex recorded from gastrosoleus muscle of healthy people. forty female subjects between 20 to 30 years of age were participated in this quasi-experimental design. twenty of them were exposed to the 100 hz curre...

background: motor function impairment occurs in approximately two-thirds of patients with subcortical stroke. repetitive transcranial magnetic stimulation (rtms) is a noninvasive technique for modulating cortical excitability. objectives: the present study was designed for assessing the efficacy of high-frequency rtms (5 hz) on ipsilesional primary motor cortex in patients with subcortical stro...

Background: Low level laser therapy (LLLT), commonly known as photo-stimulation or phototherapy has emerged. Methods: One hundred rats were used and streptozotocin (45mg /kg body weight) was applied for diabetic induction. An 2cm2 full thickness skin wound was created a specifically with a scalped in 10 groups of non-diabetic rats and diabetic rats on the shaved back of the animal. The study wa...

The aim of this work is to compare the antimicrobial efficiency of aminolevulinic acid-based photosensitization (ALA-photo) and chlorophyllin-based photosensitization (CHL-photo) against Gram-positive Listeria monocytogenes and Gram-negative Salmonella enterica, to assess some quantitative inactivation parameters of their survival curves and to propose a strategy for their effective inactivatio...

Our previous study revealed that aqueous extract of grape pomace obtained from a winemaking process could exert bactericidal action upon photo-irradiation via reactive oxygen species (ROS) formation. In the present study, we focused on chemical composition and prooxidative profile of the extract. Liquid chromatography-electrospray ionization-mass spectrometry (LC-ESI-MS) analysis showed that po...

The photo-oxidative decolorization of Direct Red 23 (DR23), a textile dye which is suspected to be carcinogenic was investigated using peroxydisulfate activated by UV irradiation and heat in a batch photo-reactor at experimental conditions. A very simple analytical method, direct UV–vis spectrophotometric detection, was utilized for the progress of photo-oxidative decolorization of dye in aqueo...

With increasing penetration of mobile devices, photo sharing services are experiencing a resurgence. Aside from providing storage, photo sharing services enable bandwidth-efficient downloads to mobile devices by performing server-side image transformations (resizing, cropping). On the flip side, photo sharing services have raised privacy concerns such as leakage of photos to unauthorized viewer...

This paper presents an approach to semi-automate photo annotation. Instead of using content-recognition techniques this approach leverages context information available at the scene of the photo such as time and location in combination with existing photo annotations to provide suggestions to the user. An algorithm exploits a number of technologies including Global Positioning System (GPS), Sem...
