INTRODUCTION Trichophyton rubrum is one of the most common species of dermatophytes which affects superficial keratinous tissue. It is not especially virulent but it can be responsible for considerable morbidity. Although there are different therapeutic modalities to treat fungal infections, clinicians are searching for alternative treatment because of the various side effects of the present th...

BACKGROUND Although several studies have demonstrated the effects of low-level laser therapy (LLLT) on skin flap viability, the role of higher doses has been poorly investigated. OBJECTIVE To investigate the inhibitory effect of the LLLT (λ=670 nm) on the viability of random skin flaps in a rat model using an irradiation energy of 2.79 J at each point. METHODS Sixteen Wistar rats were rando...

The neutron energy spectra have been calculated in the fuel region, inner and outer irradiation sites of the zero power research reactor using the MCNP-4C code and the combination of the WIMS-D/4 transport code for generation of group constants and the three-dimensional CITATION diffusion code for core analysis calculations. The neutron energy spectrum has been divided into three regions and co...

Serial studies of the serum levels of trypsin inhibitor have been performed on monkeys following injection of turpentine-falba, total body irradiation, thermal injury, splenectomy, administration of cortisone acetate and egg albumin. Following the injection of turpentine-falba mixture there was a prompt elevation in the trypsin inhibitor power of the serum. A similar response accompanied the ad...

AIM The aim of this study is to evaluate the potential effects of laser irradiation, which is commonly performed in periodontal surgery, on the surfaces of restorative materials. MATERIALS AND METHODS Five different restorative dental materials were used in this study, as follows: (1) Resin composite, (2) poly acid-modified resin composite (compomer), (3) conventional glass ionomer cement (GI...

Photovoltaic (PV) systems suffer from partial shade and nonuniform irradiance conditions. Meanwhile, each PV module has a bypass shunt diode (BSD) to prevent hotspots. BSD also causes series of peak in the power-voltage characteristics array, trapping traditional maximum Power Point Tracking (MPPT) methods local peaks. This study aims address these challenges by combining cuckoo search (CS), gr...

Nanoparticles of a one-dimensional coordination polymer [Pb(L)(μ2-I)]n (1), (Lˉ = 1H1,2,4-triazole-3-carboxylate), have been synthesized by a sonochemical process and characterized by field emission scanning electron microscopy (FESEM), X-ray powder diffraction (XRPD), FT-IR spectroscopy and elemental analyses. The thermal stability of compound 1 both its bulk and nano-size has been studied by ...

AIM To examine the effect of carbon dioxide laser irradiation on mineralization in dental pulp cells. METHODOLOGY Rat dental pulp cells were irradiated with a carbon dioxide laser at 2 W output power for 20, 40 and 60 s, and were cultured in ascorbic acid and beta-glycerophosphate containing media. Cell viability was examined 24 h after laser irradiation by a modified MTT assay. Alizarin Red ...

We present the development of a dynamic software simulation environment for modelling small and large scale photovoltaic (PV) energy generation systems. The model elements of solar panels, Maximum Power Point Trackers (MPPT) and solar inverters were integrated to a simulator system providing weather and power grid models as well as simulation of combustion power plants. The integrated system en...
