Soil is the basic foundation for any civil engineering structures and is one of nature’s most abundant construction materials for base. The most important part of a road pavement is subgrade soil and its strength. It is required to bear the loads without failure. If strength of soil is poor, then stabilization is normally needed. Subgrade is sometimes stabilized or replaced with stronger soil material so as to improve the strength. Numerous methods are available in the literature for soil stabilization but sometimes, some of the methods like chemical stabilization, lime stabilization, cement stabilization, fly ash stabilization adversely affect the chemical composition of the soil. In this study bitumen emulsion, cement and lime were mixed with dredged soil to investigate the relative strength of gravel soil in terms of Unconfined Compression Test (UCC), Bearing Capacity and California Bearing Ratio (CBR). The effect of bitumen emulsion, Cement and Lime on the geotechnical characteristics of cement and lime mixtures was investigated by conducting various tests like CBR and UCC. A little cement added to provide better soil strength. It is observed that excellent soil strength results by using cationic bitumen emulsion (CMS) with little quantity of cement used as filler. The appropriate mixing conditions for gravelly soil with CMS Bitumen emulsion have been first attempted. This is followed by deciding four particular material conditions to show the variation in dry density and CBR value to achieve the best possible strength properties of gravel soil. However, in this study, without additives soil was tested to find the Optimum Moisture Content (OMC), CBR value, Plasticity Index and Unconfined Compression Strength.

The iconic Pillars of Creation, where new stars are forming beneath dense clouds of gas and dust, have been imaged by NASA's James Webb Space Telescope as a rich, extremely realistic environment. Although they are far more porous, the three-dimensional pillars resemble beautiful rock formations. The chilly interstellar gas and dust that make up these columns may seem semi-transparent in near-infrared light. By identifying much more accurate counts of newly formed stars as well as the quantities of gas and dust in the region, Webb's new view of the Pillars of Creation, which NASA's Hubble Space Telescope first made famous when it imaged them in 1995, will aid researchers in revising their models of star formation. They will gradually get a better grasp of how stars grow in these dusty clouds over millions of years and then explode out of them.

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.
