We consider antennas that are small compared to the wavelength, and can be fitted on a small PCB. The key point regarding small antennas is that their performance is heavily dependent on their electrical size. The product of the bandwidth and the gain is a function of the size of the ...
Phthalates are chemicals that have been used for over 80 years in large quantities due to their wide range of applications, mainly in the plastic industry. For many years, these compounds were not considered dangerous for humans due to their low toxicity
Though scientists believe phthalates don't stay in human tissue forever, studies suggest that regular exposure to these chemicals can adversely affects multiple organ systems, as well as reproductive health, and child development. One study links high levels of phthalate exposure to early death in ol...
Recently the Environmental Protection Agency, EPA, put phthalates on a list of chemicals that "may present a risk" to the environment or human health. That's because they disrupt hormone activity and some preliminary studies show that they may be causing a slow and steady demasculinizing of me...

Evidence from experimental and observational studies suggests that prenatal phthalate exposures may be associated with autism spectrum disorder (ASD). We examined whether prenatal phthalate exposures were associated with an increased risk of ASD. We quan
Toxicity, risks to human health and the environment The toxicity of phthalate, as that of bisphenol A, depends primarily on its ability to migrate from the plastic in the human body. In other words, all plastic is not toxic because it contains phthalates. The risk, bringing more reliably on...
Data from the National Health and Nutrition Examination Survey for the years 20052010 were used for this purpose. Regression models with logs of these metabolites as dependent variables and age, race/ethnicity, education, pregnancy, smoking and iron storage status, study year, family poverty income ...

Widespread exposure to phthalates has been evidenced by their presence in human body fluids. We have assessed the genotoxic potential of selected phthalates and mechanism of their action in human peripheral blood mononuclear cells (PBMCs). Studied cells were incubated with di-n-butyl phthalate ...
