Beam samples containing cranial sutures were prepared from embalmed and unembalmed cranial bone and were tested to determine their flexural stiffness and strength. With the aid of layered beam theory, the flexural stiffnesses of beams containing cranial sutures were compared to hypothetical layered cranial bone beams which did not contain sutures. The bending stiffnesses and strengths of crania...

Soil (topsoil and overburden) above the granite quarry in pit 2 (two) PT. Karya Sumber Alam Perkasa has experienced a landslide. It is probably caused by condition of slopes at Perkasa, which currently being mined, quite steep. External factors that can trigger movement rock masses are vibrations due to breakers. This potential increase risk slope stability. Slope stability influenced geologica...

This paper presents an experimental study of laser interferometry-based closed-loop motion tracking for flexure-based four-bar micro/nano manipulator. To enhance the accuracy of micro/nano manipulation, laser interferometry-based motion tracking control is established with experimental facility. The authors present and discuss open-loop control, model-based closed-loop control, and robust motio...

Landslide hazard characterization in the Setijhora landslide, located near Kalijhora village, along National Highway 10, was carried out a qualitative way using Rock Mass Rating (RMR), Continuous Slope (CSMR) and Geological Strength Index (GSI). CSMR data helped understanding of slope failures (wedge, planner, rotational toppling), while RMR & GSI provides better rock mass quality its deformati...

Rock block tilting is one of the most common types dangerous rock failures with no clear indicator displacement prior to failure. Existing stability evaluation methods remain limited in their ability constrain non-penetrating section area, which closely related stability, and evaluations are therefore associated large uncertainties. The dynamic characteristic parameters toppling structural plan...

Splenic flexure volvulus is rare, only 22 cases having been reported. Though these usually present with chronic intermittent clinical features we recently encountered a case presenting as acute intestinal obstruction which, on plain abdominal X-rays, had classical features of this condition.

By combining the influence of excess alcohol, temperature and monomer-to-initiator ratios in the feed, dinuclear salan aluminum complexes L(R)Al(2)Me(4) exhibited a high degree of control towards the copolymerization of L-LA and ε-CL, producing blocky, gradient, tapered and random copolymers.
