Inefficient soil characteristics are a major problem in engineering projects today. Sometimes the first stage in the building is to change the characteristics of inappropriate soil. Early signs of degradation in pavement structures on low soil subgrades include pavement that fails too soon. The potential for clayey soil to exhibit unfavorable engineering features, such as low bearing capacity, high shrinkage, swell characteristics, and high moisture susceptibility, is typically present. It is common practice to stabilize these soils to increase their strength. In order to enhance the engineering performance of soil, a technique called soil stabilization is used to add a binder to the soil. This study details how the addition of both lime and fly ash increased the cohesive soil's strength in the surrounding area. Fly ash has been used to bind non-cohesive soil, granular soil, or soil that is poorly cohesive in place of the typical usage of lime alone in soil that contains clay and is highly cohesive. Fly ash is mostly utilized to support the base course or sub-base.

A new study has shown that many of the complaints about the effects of coronavirus vaccines on periods were valid. Twenty-nine thousand people around the world were studied on a wide range of factors and compared with those who hadn’t been vaccinated. The results showed that people who received the vaccination experienced an average delay in getting their periods by 1 day compared with those who hadn’t been vaccinated. The study published in the British Medical Journal Tuesday reports on data from a popular period-tracking app called Natural Cycles, which includes women from around the world. Most of the participants were from North America, Britain, and Europe; researchers analyzed 14,936 cycles among those who received the vaccine and 4686 cycles among those who did not. Because users tracked their menstrual cycles every month on the app—which included information about contraceptive use and other factors—researchers were able to analyze three menstrual cycles before vaccination and at least one cycle after. They compared these results with four cycles in unvaccinated participants.
