Abstract In recent years, extrusion 3D printing processes have undergone an important development. They allow obtaining complex shapes in easy way and relatively low cost. Different plastic materials can be printed with the fused filament fabrication (FFF) technology. Bioinert ceramics such as alumina or zirconia excellent physical mechanical properties (high melting point, high strength…) that...

We determine the inviscid dynamics of a point vortex in the vicinity of a flexible filament. For a wide range of filament bending rigidities, the filament is attracted to the point vortex, which generally moves tangentially to it. We find evidence that the point vortex collides with the filament at a critical time, with the separation distance tending to zero like a square root of temporal dist...

The design and development of machine tools play a vital role in the current economic growth. It facilitates reduction manufacturing cost coping with quickly changing business environment. During tool, dynamic characteristics need to be calibrated for avoiding uncertainties. This paper investigates design, characteristics, single screw conveyor which is used blend waste plastic material catalys...

the development of yielded or failure zone due to an engineering construction is a subject of study in different disciplines. in petroleum engineering, depletion from and injection of gas into a porous rock can cause development of a yield zone around the reservoir. studying this phenomenon requires elasto-plastic analysis of geomaterial, in this case the porous rocks. in this study, which is a...

During cell locomotion and endocytosis, membrane-tethered WASP proteins stimulate actin filament nucleation by the Arp2/3 complex. This process generates highly branched arrays of filaments that grow toward the membrane to which they are tethered, a conflict that seemingly would restrict filament growth. Using three-color single-molecule imaging in vitro we revealed how the dynamic associations...

The disturbances of a quiescent filament and associated evolution of photospheric magnetic field were examined. The whole filament was broken into three sections by two filament breaks. In different sections, three distinct disturbances took place: two major ones with similar characteristics and a transient one. The presence of filament twist and the highly sheared filament magnetic field were ...

Adhesion of motile flagella to the cell body in Trypanosoma brucei requires a filamentous cytoskeletal structure termed the flagellum attachment zone (FAZ). Despite its essentiality, the complete molecular composition of the FAZ filament and its roles in FAZ filament assembly remain poorly understood. By localization-based screening, we here identified a new FAZ protein, which we called FAZ2. K...

topical application with 100, 200 and 300 ng/ml phytohormone salicyclic acid on commercial traits was analysed in bivoltine csr2, csr4 and csr2xcsr4 crossbreed races of the silkworm, bombyx mori l. the results showed that there was significant increase in larval weight female cocoon weight, male cocoon shell weight, and hatching percentage with 100 and 200 ng/ml, silkgland weight, female cocoon...
