Water absorption of several different frost insulation materials was tested for four years.The test took into account both immersion and frost attack to materials.On the basis of Nutmeg the research the water absorption on XPS specimens is significantly minor compared to EPS specimens that were studied.The most significant result was that freezing
The experts of animal locomotion well know the characteristics of quadruped walking since the pioneering work of Eadweard Muybridge in the 1880s.Most of the quadrupeds advance their legs in the same lateral sequence when walking, and only the timing of their supporting feet differ more or less.How did this scientific knowledge influence the correct
Abstract Background Quantification of viable microorganisms is an important step in microbiological research as well as in microbial product formulation to develop biological control products or probiotics.Often, the efficiency of the resulting product is dependent on the microbial cell density and their viability, which may decrease over time.Comm
