Geometrical Approach To Length-Biomass Allometry In Predominantly Bidimensional Seaweeds, Ji-Huan He
Geometrical Approach To Length-Biomass Allometry In Predominantly Bidimensional Seaweeds, Ji-Huan He
Ji-Huan He
Scosati studied experimentally length-biomass allometry in primary producers (vascular plants and unicellular microalgae), and found the allometric exponent (0.5, 95% confidence) differs significantly from the “universal” value, 0.25 suggested by Niklas and Enquist. Here, a geometrical similarity is proposed to elucidate Scosati’s findings.
Nano Bubble Dynamics In Spider Spinning System, Ji-Huan He
Nano Bubble Dynamics In Spider Spinning System, Ji-Huan He
Ji-Huan He
A possible mechanism in the spider-spinning process is illustrated and a nanobubble dynamical model is suggested. The spinning system consists of thousands of nano scale spigots and a bubble can be produced at the apex of each nano-spigot. Nano-effect enables the dragline silk to have of extraordinary strength and toughness, while the extremely small surface tension of nanobubbles enables the spider to use an awfully small force during the spinning procedure.
Hierarchy Of Wool Fibers And Fractal Dimensions, Jie Fan, Jun-Fang Liu, Ji-Huan He
Hierarchy Of Wool Fibers And Fractal Dimensions, Jie Fan, Jun-Fang Liu, Ji-Huan He
Ji-Huan He
Wool fiber shows excellent advantages in warmth-retaining and many other practical properties possibly due to its hierarchical structure. Its fractal dimension of wool fiber is calculated which is very close to the Golden Mean, 1.618. The present study might provide a new interpretation for the reason why wool fiber has so many excellent properties
Fatalness Of Virus Depends Upon Its Cell Fractal Geometry, Ji-Huan He
Fatalness Of Virus Depends Upon Its Cell Fractal Geometry, Ji-Huan He
Ji-Huan He
Why do more complex viruses (e.g., HIV, AIDS-virus and SARS coronavirus) tend to be more fatal? The paper concludes that the cell fractal geometry of viruses is the key. This paper also suggests two possible new approaches using nanotechnology and temperature to cure or prevent virus infection
