Phthalates are esters of phthalic acid, mainly used as plasticizer in polymeric packaging materials. The main objective of this research was to determine the exact roots of the phthalate esters in the Iranian flexible/laminated packaging films commercially used for food products such as ketchup, spaghetti, mayonnaise, black tea and snack foods. This investigation was carried out by analyzing th...

The work presents application of previously proposed approach for transverse profile forming high energy electron beams with plastic samples made using 3D printing technology. collimator PLA (polylactide) is designed and produced in a frame this work. results 6 MeV beam clinical linear accelerator Elekta Synergy presented. Obtained comparison data from XiO dosimetry planning system shows good a...

During recent decades due to the increase in pollutants release from various industries, reduction or elimination of volatile organic compounds VOCs has become one of the main purposes of researches in order to protect the environment. In this research, two acrylic emulsion resins and an adhesion promoter polyester emulsion resin were used to optimize water-based printing ink formulation for pr...

Photoplethysmography (PPG) devices are widely used for monitoring cardiovascular function. However, these devices require skin contact, which restricts their use to at-rest short-term monitoring. Photoplethysmographic imaging (PPGI) has been recently proposed as a non-contact monitoring alternative by measuring blood pulse signals across a spatial region of interest. Existing systems operate in...

The Data Availability Statement appearing with the published article is incorrect. The correct Data Availability Statement should read: There are legal restrictions on the student outcome data. National Child Measurement Programme data was used as determined by the data sharing agreement with the then Information Centre of the National Health Service (NHS IC), now Health and Social Care Informa...

Powder-based inkjet 3D printing method is one of the most attractive solid free form techniques. It involves a sequential layering process through which 3D porous scaffolds can be directly produced from computer-generated models. 3D printed products' quality are controlled by the optimal build parameters. In this study, Calcium Sulfate based powders were used for porous scaffolds fabrication. T...

Creating sustainable bioeconomies for the 21st century relies on optimizing the use of biological resources to improve agricultural productivity and create new products. Arbuscular mycorrhizae (phylum Glomeromycota) form symbiotic relationships with over 80% of vascular plants. In return for carbon, these fungi improve plant health and tolerance to environmental stress. This symbiosis is over 4...
