background diabetic foot ulcer is a worldwide health care concern affecting tens of thousands of patients. if these ulcers left untreated, they can create severe complications. objectives this study was designed to examine the effect of infrared radiation on the healing of diabetic foot ulcer. patients and methods this clinical trial was performed on 50 patients referred to dr. ganjavian hospit...
Although, that the solar energy is important for life continuity, there is need to protect large buildings from these radiations in summer and if the buildings are permitted to take these radiations, the cost of cooling will be too much. One of the most effective methods used to solve this problem is to coat buildings with specific pigments that reflect the solar infrared radiation. This wo...
Infrared imagers are important for reorganization and monitoring. This paper discusses the design of an infrared imager. Optical design in medium wavelength infrared (MWIR) and long wavelength infrared (LWIR) bands is different and needs distinct detectors and materials. Reflective systems are not suitable due to their small field of view (FOV) and vignetting. Refractive dual band optical syste...
abstract in this study, we synthesized a novel template polymer by using methacrylic acid (mma) as functional monomer, ethylene glycol dimethacrylate(egdma) as cross linker, 2,2-azobisisobutyronitrile (aibn) as initiator and olanzapine as targeted molecule in the presence of chloroform and acetonitrile as solvent. the products have been characterized and confirmed by (chn)elemental analysis,...

The infrared night vision illuminates are a kind of flare that, with radiation in the near infrared range (700-900 nm) cause illuminates the target in the battlefield and night operations. These illuminates have problems such as low infrared radiation, low burning rate, and so on. Many physical and chemical parameters affect the burn rate and radiation intensity. But the most effective paramete...
the synthesis of [cu3o(oac)6(h2o)3]cl.ch3oh.6h2o is described. the x-ray crystallographic study of thecomplex revealed an isosceles triangle of copper atoms with a triply bridging oxo atom nearly in the plane of thetriangle. the coordination sphere around each metal center is close to distorted octahedral and the central{cu3(μ3-o)} core is planar. every two copper atoms were connected to each o...
abstract background: in recent years, infrared thermography tools are used for viral disease detection. however, no study has been to evaluate the value of this device. the current study was designed to review the effectiveness of infrared thermography technique for diagnosis of viral diseases in international airports. materials and methods: this study was conducted as a systematic review. all...
Objective: The main objective pursued in this paper is to investigate the energy consumption for drying of potato slices using vacuum-infrared drying method. Methods: Drying of potato slices with the thicknesses of 1, 2 and 3 mm were conducted at vacuum levels of zero (without vacuum), 20, 80 and 140 mm [Hg], infrared radiation at power levels of 100, 150 and 200 W in the three repetition. Resu...
