When printing a plate (or dish) by an FDM 3D printer, the process normally requires support material, which causes several problems. This paper proposes a method for forming thin plates without using wasteful support material. This method requires several extraordinary parameter values when slicing plates. The experiments show that the plates can, for the most part, be successfully formed using...

The implementation of the voicing of the English word-final obstruents constitutes a serious problem for foreign speakers of English whose native languages organize the phonological 'voicing' contrast differently. Polish teachers and learners of English implement too few and too sharply-cut rules whose application produces unnatural rendering of the English voicing distinction, with overemphasi...

Trees are valued in California’s urban areas for the many benefits they provide, including modification of the local environment. Besides serving as a source of oxygen and water vapor, trees give off other chemical compounds into the atmosphere, including volatile organic compounds (VOC) that can react in the atmosphere and contribute to the formation of ozone, a principal air quality problem i...

Nanoparticles made of biodegradable polymers has become the best approach for nanoparticle making due to their compatibility with the human body. New glycerol adipate polymers with hydroxyl group substituted with different percent of acyl group, sited as figures within the abbreviated name in the text, and triptophan were synthesized and proposed to be used in the preparction of dexamethason ph...

The main objective of this project was to investigate the behavior and the damaging effects of hot tear segregations in the continuously cast steel blooms on the final product quality. To achieve this aim, plant data from three different types of steels were used. Investigations using the scanning electron microscope (SEM) equipped with energy dispersive x-ray spectroscopy (EDS) probe and metal...

Abstract In this paper, we study the packing optimization problem of square plates under conditions that cutting mode is guillotine cut, number stages cannot exceed 3, and order sequence not considered. Because it difficult to determine constraint in process stacking items into stacks, divide nonlinear integer programming model two establish: one stage stacks followed by splicing them stripes, ...

Syntheses of ZSM-5 coatings on stainless steel plates were carried out via the substrate heating method. The reaction mixture was kept at temperatures below 100 C, while the metal plates were heated to temperatures above 100 C. It was demonstrated that continuous ZSM-5 coatings of different textures with different crystal morphologies and void fractions could be formed. ZSM-5 coatings were char...
