Slope of Dry Granular Materials Surface is Generally Curved
Fathan Akbar, Elfi Yuliza, Nadya Amalia +2
As if it has become a consensus that the slope of the granular heap is straight, and from that, an angle of repose is defined. However, closer inspection shows that the slopes are…
How a Snake Can Raise its Neck High although its Body is Very Soft. Similarity with a Thin Plastic Tube Filled with Air
Handika Dany Rahmayanti, DesyanaOlenka Margaretta, Nadya Amalia +5
The bodies of snakes, such as king cobras, are very soft so that it is nearly impossible for them to raise their heads higher than around one meter. By direct measurement, we were…
Second Order Phase Transition and Universality of Self-Buckled Elastic Slender Columns
Desyana Olenka Margaretta, Nadya Amalia, Fisca Dian Utami +2
Self-buckling is an interesting phenomenon that is easily found around us, either in nature or in objects made by human. Palm fronds which initially directed upward when they were…
Stability of Granular Tunnel
Elfi Yuliza, Nadya Amalia, Handika Dany Rahmayanti +4
We demonstrated the stability of tunnels made of granular matters is strongly dependent on the grain size, tunnel diameter, and water content in the granules. Larger tunnel radius,…
Thickness Effect on Fluctuation of Electron States in Thin Film and Implication to Lattice Constant Change Due to Size Reduction
Mikrajuddin Abdullah
We propose a model for predicting the fluctuations of electron states in thin films as function of film thickness. The model was derived based on the assumption of the existence of…
Reduction in Rebound of Concrete Piles Driven into Clays by Coating Pile Surface with Titanium Dioxide Nanoparticles
Nadya Amalia, Asifa Asri, Mamat Rokhmat +2
Using a model for concrete piles driven into clays, we compared penetration depths between uncoated piles and piles coated with titanium dioxide (TiO2) nanoparticles. The behavior…
