The production of ROS was studied on white blood cells as a model to screen the effect on eukaryotic cells after being exposed to samples and solar simulated irradiation (according to the level of penetration under the skin). For that purpose, the leukocytes were separated from anticoagulated fresh blood using the Ficoll-Hypaque reactive in a well-known technique [33]. Then, 50 μL of suspensions of P25TiO2NPs (0.2 mg/mL and 0.02 mg/mL), vitaminB2@P25TiO2NPs (0.2 mg/mL and 0.02 mg/mL) and vitamin B2 (0.2 mg/mL and 0.02 mg/mL) were prepared and mixed with 50 μL of white blood cells suspension. A solution of 3% H2O2 was used as positive control and PBS as negative control. Then, the samples were irradiated using the LED panel for 3 and 6 h to simulate the light penetration into the skin. Also, a set of samples was kept in the dark as control. Finally, the ROS were detected through the colorimetric assay employing the nitroblue tetrazolium salt (NBT salt) and the absorbance at 650 nm was measured. The experiment was reproduced twice; the standard deviation was calculated and p-value < 0.05 were considered significant.

  • The operational mechanics of a split sleeve repair clamp are relatively straightforward. When a leak occurs, the split sleeve is positioned over the damaged section, effectively covering the compromised area. By tightening the bolts, the clamp expands to encapsulate the pipe, pressing the sleeve firmly against it. This action not only seals the leak but also reinforces the structural integrity of the pipe, preventing future failures. The simplicity of this mechanism makes split sleeve clamps an attractive choice for quick and effective repairs.

  • FRP manhole covers are removable panels used to cover manhole covers, to prevent anyone from entering the cover and to prevent falling into it. Different types of materials are used to manufacture manhole covers. Cast iron and concrete materials are widely used to manufacture manhole covers, but they have disadvantages such as their high weight, high cost, and tendency to encounter water.

  • First and foremost, the environmental implications of choosing used bike racks are significant. The production of new bike racks involves the extraction of raw materials, energy consumption, and the emission of greenhouse gases. By purchasing a second-hand bike rack, consumers are effectively reducing demand for new products, thus minimizing their carbon footprint. This simple choice aligns with the principles of sustainability and encourages a circular economy where products are reused instead of being discarded.
