Chemical image fusion refers to the combination of chemical images from different modalities for improved characterisation of a sample. Challenges associated with existing approaches include: difficulties with imaging the same sample area or having identical pixels across microscopic modalities, lack of prior knowledge of sample composition and lack of knowledge regarding correlation between mo...
The Corbino approach, where the sample of interest terminates a coaxial cable, is a well-established method for microwave spectroscopy. If the sample is dielectric and if the probe geometry basically forms a conductive cavity, this combination can sustain well-defined microwave resonances that are detrimental for broadband measurements. Here, we present detailed simulations and measurements to ...
food preservation has always been a concern for mankind. different methods have been developed to preserve food for long periods, such as cold storage, plastic covers, and modified atmospherethis study examined the physicochemical and biological effects of a modified atmosphere on packaged romaine lettuce at three levels (g1: 40% oxygen, 15% carbon dioxide, 45% nitrogen; g2: 70% oxygen, 15% car...
Dispersive Liquid-Liquid Microextraction / Thermal Lens Microscopy (DLLME/TLM) was developed as a new combination method for preconcentration and determination of Cd. Thermal Lens Microscopy is suitable for the determination of analyte after DLLME because of the low volume of the remained phase after DLLME and increasing of the enhancement factor for the nonpolar organic solvents. Some effe...
The aim of conducting this research was to evaluate the viscosity change in the continuous casting of steel mold powders by altering their chemical compositions, using hot stage microscope analysis. 4 low-fluorine samples containing such compositions as MnO, Fe2O3, Li2O, TiO2 and ZnO, as well as another fluorine-free sample containing a combination of Fe2O3 and TiO2, were prepared in this resea...
The purpose of this study was to find a combination of nanocomposite polymer with biomechanical and physical properties suitable for use in the treatment of nerve damage.In this research PCL and PHBV with a ratio of 25/75, 10/90 And its nanocomposites were prepared using the same MWCNT nanoparticle with different weight percentages of 1 and 3 wt% by solvent method. To evaluate morphological...
Backgrounds: Finding an efficient biomarker or combination of them as predictors of early-onset neonatal sepsis is very important. On the other hand, the use of umbilical cord blood samples in laboratory tests, along with its simplicity and availability, reflects neonate metabolic status. Background and Aim: The aim of this study was to investigate the association between umbilical cord bloo...
conclusions our study indicated a high frequency of cotrimoxazole resistance gene in e. coli isolates from ilam and tehran (milad) hospitals, and sul genes had a major role in cotrimoxazole resistance of these isolates. materials and methods one-hundred and forty-four e. coli isolates were identified during march 2007 to april 2012 at ilam hospitals and milad (tehran) hospital. antibiotic susce...
