Abstract Additive manufacturing or 3D-Printing technology is being utilized heavily in recent times, especially a range of industries. Many types and sizes 3D-printers are producing ceramic, metal, plastic components. This serving society many aspects, such as minimizing environmental impact, reduction cost, even material consumption. Polylactic acid (PLA) thermoplastic filament type used Fused...

Gavril [GA4] defined two new families of intersection graphs: the interval-filament graphs and the subtree-filament graphs. The complements of intervalfilament graphs are the cointerval mixed graphs and the complements of subtree-filament graphs are the cochordal mixed graphs. The family of interval-filament graphs contains the families of cocomparability, polygon-circle, circle and chordal gra...

this work has setup to determine the effects of a solvent on the structure and properties of polypropylene fibres with different physical structures. samples of continuous filament yarns with different physical structures (partially oriented (poy) and drawn yarns) are treated with decahydronaphthalene (decalin) at 28, 55, 75 and 95oc. at 95oc, the samples are dissolved completely in decalin and...

Traditional additive manufacturing (also known as 3D printing) of continuous carbon fiber reinforced plastic (CCFRP) lacks the ability to manufacture parts with high speed and energy efficiency. This is mainly because contact needed slow heat transfer from conventional hotend composite filaments. A microwave heating assisted method here presented which allows CCFRP a higher compared methods. Th...

Amorphous polymers exhibit a viscoplastic strain hardening behavior at large strains. To describe this behavior, we have developed an effective temperature model for the nonequilibrium of amorphous that incorporate effects network orientation and relaxation plastic deformation. The development is introduced as backstress produces kinematic in stress response, while describes rate on response. w...

This paper presents an experimental study of topology-optimised passive heat sinks produced in a thermally-conductive plastic using material extrusion additive manufacturing. The thermal performance the filament is investigated through test printing, conductivity testing and scanning electron microscope imaging. Topology optimisation used to generate novel sink designs for cooling natural conve...

Ultrasonic welding is a high-frequency method of that uses mechanical energy to generate heat. This clean and very suitable for plastic welding. In this study, using the Taguchi experimental method, control factors an ultrasonic machine were optimized affect durability knots trawl nets made from polyamide (PA) polypropylene (PP) filaments as alternative traditional mesh knitting method. After o...

In muscle, force emerges from myosin binding with actin (forming a cross-bridge). This actomyosin binding depends upon myofilament geometry, kinetics of thin-filament Ca(2+) activation, and kinetics of cross-bridge cycling. Binding occurs within a compliant network of protein filaments where there is mechanical coupling between myosins along the thick-filament backbone and between actin monomer...

How intracellular transport controls the probability that cargos switch at intersections between filaments is not well understood. In one hypothesis some motors on the cargo attach to one filament while others attach to the intersecting filament, and the ensuing tug-of-war determines which filament is chosen. We investigate this hypothesis using 3D computer simulations, and discover that switch...

The nucleotide turnover rates of bipolar myosin thick filament along which actin filament slides were measured by the displacement of prebound fluorescent ATP analog 2'(3')-O-[N-[2-[(Cy3)]amindo]ethyl] carbamoyl]-adenosine 5' triphosphate (Cy3-EDA-ATP) upon flash photolysis of caged ATP. The fluorescence of the thick filament where actin filament slides decayed with two exponential processes. T...
