Spitting is a human reflex as old as civilization, related, mainly, as is shown, to the evacuation of internal contamination with alpha-emitting nanoparticulates, a contamination with many causes, from car fumes and industrial smokes, coal ashes and cement, radon, phosphated fertilizers, to depleted uranium weapons and natural dust and tap water in areas of high natural radioactivity, as well as cigarettes, for the main sources. Strong levels of coal ash pollution together with high natural radioactivity explain for instance the spitting “custom” in Chinese streets, together with long distances between workplace and home, widespread cigarette use, and lack of public toilets. Alphaemitting nanoparticulates become a part of the digestion cycle in meat-eaters, but not without collateral damage.

This paper presents results of the author on Salvia officinalis and Salvia microphylla and COVID19. The results were achieved with dried Salvia officinalis leaves and with fresh Salvia microphylla leaves. The properties of fresh leaves appear with the taste as being much richer in antiviral agents, drying reduces the antiviral activity. The experiments presented in this paper are on the author himself, do not involve biosampling to confirm in laboratory but existing data in the published literature confirms the excellent efficiency of Salvia officinalis against COVID19 and a large array of other diseases. The self-experiments were very successful against COVID19, opening a path for natural treatment.

Innovations assets during the pandemic time and gradually commitment formed it fundamental to transform traditional education methods and made current many crucial breakpoints in the educational process in early childhood education. The present study is an augmentation to the issue of the virtual learning environment at preschools. Multiplying the lines of open and distance learning, including cyberculture as a new note in learning, attracting the Internet as a source and means of teaching, increasing in real-time the links between computer-mediated education partners, reporting on cyberspace as a privileged environment, on the performance of the education, in general, are conclusive examples of the stated evolution. It does not mean that everything in school is moving from the current to the virtual. This study selected descriptive survey research for quantitative methods. The research design used appropriate frequencies to collect responses through an online data from Facebook group members ("Pregătim preşcolarii pentru şcoală"). The target population comprised of 280 parents in Romania. One-self administered questionnaires were used to obtain data on parents' perceptions of conventional schooling and in decision making, they should involve pupils in a homeschool setting. We suggest that a parent's moderate degree of engagement through online learning is essential as it involves reinforce to a child. The results provided here shows that learning process based on inquiry-approach could contribute to the development of home education programs and curriculum resources and materials for early childhood education. Also, present the perspectives of accelerated curricula for gifted children from the mainstream education system during pandemic times.

This subcritical concept is framed in a way that allows use in a single room for some electricity production purposes. It involves a tungsten casing and also helps using depleted uranium dust. The single series of anneals for closure and direct laying of the top opening window onto the left side of the tungsten casing make pressure work impossible ; it also allows for a relatively cheap production.
