Petrichor Petrichor (/ˈpɛtrɨkɔər/) is the earthy scent produced when rain falls on dry soil. The word is constructed from Greek, petra, meaning ‘stone’ + ichor, the fluid that flows in the veins of the gods in Greek mythology. In 2015, MIT scientists used high-speed cameras to record how the scent moves into the air.[5] The tests involved approximately 600 experiments on 28 different surfaces, including engineered materials and soil samples.[6] When a raindrop hits a porous surface, small bubbles form that float to the surface and release aerosols.[5] Such aerosols carry the scent as well as bacteria and viruses from the soil.[5] Raindrops that move at a slower rate tend to produce more aerosols; this serves as an explanation for why the petrichor is more common after light rains.[5] Some scientists believe that humans appreciate the rain scent because ancestors may have relied on rainy weather for survival.[7] References[edit] Jump up ^ Bear, I.J.; R.G.

Database introduction Introduction BiblioMap, the EPPI-Centre database of health promotion research, contains over 14,100 records at present. The studies included in Bibliomap have been compiled over a number of years as a result of searching and coding research for inclusion in systematic reviews at the EPPI-Centre. All studies are coded for specific characteristics of health focus, population group and study type. Using Bibliomap Searches can be carried out using keyword and free-text terms. To record results of your searches, you can print out your searches or reports, or cut and paste the table into word processing software. How current is the register? Bibliomap is updated each time a systematic review is completed within the EPPI-Centre's Health Promotion and Public Health Reviews Facility. User consultation on the EPPI-Centre Health Promotion and Public Health Research Registers We welcome any feedback on the utility and usability of Bibliomap.
Virtual Medicine Online Open Access Journals Free video lectures,Free Animations, Free Lecture Notes, Free Online Tests, Free Lecture Presentations Database introduction Introduction DoPHER is unique in its focussed coverage of systematic and non-systematic reviews of effectiveness in health promotion and public health worldwide. This register currently contains details of over 2,500 reviews of health promotion and public health effectiveness. All reviews are assessed and coded for specific characteristics of health focus, population group and quality. They have been systematically keyworded with: generic keywords (e.g. health focus and population group), keywords concerning review quality (aims, search, inclusion criteria, quality assessment methods, data extraction methods and analysis methods). To record results of your searches, you can print out your searches or reports, or cut and paste the table into word processing software. How are the reviews identified? Since January 2006 DoPHER is updated quarterly to keep it as current as possible. User consultation on the EPPI-Centre Health Promotion and Public Health Research Registers
