We report a diverted route to [1]rotaxane and tris-branched [1]rotaxane that are devoid of any efficient template and which could not be obtained by classical straightforward strategies. The described chemical route relies on the utilization of a "macrocycle transporter", which is able first to bind a macrocycle, second to link temporarily a triazolium-containing molecular axle, and third to de...

The rollover tendency of upland farm machinery needs to be carefully considered because crop fields are typically irregular, and accidents frequently result in injuries even death the operators. In this study, characteristics an underdeveloped 12 kW automatic onion transplanter were determined theoretically evaluated through simulation validation tests considering mounting position transplantin...

A recursive non-linear model was developed for the prediction of pavement performance as a function of traffic characteristics, pavement structural properties and environmental conditions. The model highlights some of the advantages of relaxing the linear restriction that is usually placed on the specification form of pavement performance models. First, a functional form that better represents ...

A new [2]rotaxane host system containing nitro-isophthalamide macrocycle and polyether functionalised pyridinium axle components is prepared via clipping and stoppering synthetic methodologies using chloride anion templation. After removing the chloride anion template, (1)H NMR titration experiments reveal the unique interlocked host cavity to be highly selective for binding chloride and bromid...

In this research, Ride quality of a three-axle truck is investigated to understand its vibration specifications and influence of it on special load. The truck is Benz 2624, and the load is rather sensitive to vibrations. The system is considered for an off-road duty. Hence, the vehicle is modeled as a nineteen-degree of freedom system and its equations of motion are derived by employing Lagrang...

Abstract Some of the factors causing early damage to Indonesia’s flexible pavement system in Indonesia were allegedly caused by several things, including Equivalent axle load (EAL) equation incompatible with situation where most heavy vehicles carry overloaded loads. One effort that can be done avoid severe road is overlaid pavement. It suspected overlay on will affect shape EAL equation. This ...

Abstract Infrastructure worldwide is facing the challenge of aging bridges and increasing traffic loads. Prolonged serviceability safety these structures can be enabled by Structural Health Monitoring (SHM) methods. Knowledge actual operating loads critical for evaluation remaining service life. However, direct measurement challenging requires a significant financial investment. Bridge Weigh‐In...
