Is COVID-19 Infection Transmitted Through Food?

 Coronavirus disease (COVID) has had a growing outbreak around the world. China reported COVID-19 infection for the first time in December 2019. Symptoms of this disease often include respiratory symptoms, but gastrointestinal symptoms (nausea, vomiting, and diarrhea) were also reported in COVID-19 infection. Coronavirus transmits through direct droplets, contact, or fomites. However, other mod...

Man made deltas

The review of geochronological and historical data documents that the largest southern European deltas formed almost synchronously during two short intervals of enhanced anthropic pressure on landscapes, respectively during the Roman Empire and the Little Ice Age. These growth phases, that occurred under contrasting climatic regimes, were both followed by generalized delta retreat, driven by tw...

Man-made Mineral Fibres

practice, the detection Ii mit of scanning electron microscopy is about 0.1 j.m (Middleton, 1982). Transmission electron microscopy may be required to detect very thin fibres (Rood & Streeter, 1985). The elemental composition of individual fibres can be determined with an energy-dispersive X-ray ana1ysis attachment combined with an electron microscope (Middleton, 1982). Fibres are counted and s...
