Abstract:

The effect of hot multistage drawing conditions on the structure and properties of nylon 6 fibers was investigated by varying second stage draw ratio. Total draw ratio was changed from 3.3 to 5.775 to clarify the structural changes in nylon 6 fiber at a broad range of draw ratio. The structural development of the fibers was studied with FTIR spectroscopy, differential scanning calorimetry (DSC), optical microscopy, and tensile testing. A continuous drop of the γ crystalline form content is observed as a function of draw ratio, in parallel with an increased content of α crystalline phase. The γ

Abstract:

This paper argues that the vertical spread of computer-assisted language learning (CALL), i.e., a spread throughout language materials and curricula, makes it difficult to draw a clear distinction between CALL and other language materials. In view of the emphasis that teachers, researchers, and administrators have placed on evaluating CALL, I argue that some valuable lessons about materials evaluation can be drawn from reflection on issues in CALL evaluation. In particular, I discuss the opportunities for professionals to reconsider assumptions held about comparative research, draw upon resear

Abstract:

Concave/convex wall features are usually generated in the deep-drawn parts with complicated geometry, especially the difficult-to-deep draw materials. The application of the draw bead could reduce the concave/convex wall features. However, it is difficult to determine the suitable draw bead geometry and its position to obtain a straight wall. In this study, the effects of draw bead height were investigated using the finite element method (FEM) and experiments. The application of the draw bead and the effects of its height on the concave/convex wall features could be theoretically clarified on

The mechanical yielding and necking behaviors of metallocene-catalyzed high density polyethylenes were investigated from a structural point of view. In particular the natural draw ratio was investigated with different crosshead speeds, molecular weights, and the cross-section shapes of sample specimens. We proposed a structural model for explaining the necking formation in addition to the molecular weight and the cross-sectional shape dependences of the natural draw ratio.

Abstract High-modulus and high-tenacity polypropylene fibres were prepared by drawing as-spun filaments on a heater with a temperature gradient. The results on two different MFI PP show that the fibre properties are significantly affected by the temperature profiles at the final stage of drawing on a gradient heater. High crystal perfection and crystallinity at very high draw ratios have been obtained for the gradient drawn fibres. The gradient drawn filaments showed superior mechanical properties when compared to filaments drawn over a constant temperature heater. Fibres with an initial modul

HDPE-based nanocomposite fibers have been extruded from a melt and drawn up to draw ratio DR = 8. Two kinds of carbon nanodiscs (original ones and those exposed to additional annealing) have been used as fillers. Obtained nanocomposite fibers have been investigated with the help of different experimental methods: rheology, SEM and WAXS. It has been demonstrated that the annealed carbon nanodiscs possess a nucleation ability that finally leads to strong transformation of the material morphology.

Abstract:

The settlement of the American West was directly dependent on the extraction of resources including minerals, precious metals, timber, and the commerce that resulted. The infrastructure that developed around these extraction activities was intended to be merely functional, and therefore temporary. Readily available forest resources made timber structures relatively inexpensive and easy to build; they could be put into service quickly and were adequate to immediate needs. Many of these structures survive today at former mining and milling sites, along with remnants of the railroad lines that se

Abstract:

Initially amorphous PET sheets were prepared from recycled flake made from post-consumer PET bottles. Drawing and/or rolling of the sheets were performed at 80°C using a draw ratio up to 4.2. The influence of draw ratio on the structure, molecular orientation, and mechanical properties of drawn sheet was investigated. Not only was the tensile strength at yield stronger, but the modulus of the deformed sheets was much higher than that of as- extruded sheets. This was attributed to the enhanced chain orientation and crystallinity of PET with increasing draw ratio. In this work, no particular inf

Abstract:

In an effort to improve performances of forward osmosis (FO) systems, several innovative draw spacers have been proposed. However, the small pressure generally applied on the feed side of the process is expected to result in the membrane bending towards the draw side, and in the gradual occlusion of the channel. This phenomenon potentially presents detrimental effects on process performance, including pressure drop and external concentration polarization (ECP) in the draw channel.

Abstract:

The properties of false-twist textured yarns in the aspects of crimp characteristic and tensile behavior depend mainly on the draw ratio and the D/Y ratio. This study comprises investigations of the effect of D/Y ratio and draw ratio on the crimp and tensile properties and percent crystallinity. While there was no noticeable change on the percent crystallinity by altering these parameters, tenacity increased and crimp contraction decreased with increasing draw ratio, and crimp stability decreased when the D/Y ratio increased. K/S value also decreased with increasing draw ratio.

As the draw height increases, both the major and minor axes of the extraction zone’s maximum cross-section continuously enlarge, stabilizing beyond a draw height of 80 cm.

Abstract:

Background and Objectives: A reduction forced toward the posterior side during graft fixation may help to lessen anterior tibial translation after ACL reconstruction. The purpose was to compare the clinical and radiological outcomes of graft fixation when a posterior draw was used and when it was not used during anterior cruciate ligament (ACL) reconstruction surgery. Materials and Methods: Of 110 patients who had undergone primary arthroscopic ACL reconstruction between January 2017 and August 2020, in all, 76 patients had been operated on without a posterior draw (non-draw group), and 34 pat

AbstractThe world of patents has always expanded exponentially in line with innovative inventions and materials, and this has been particularly true in the first few decades of the 21st century, which have delivered numerous construction materials and jointing and bonding techniques. ETH Zurich's Silke Langenberg, Sarah M Schlachetzki and Robin Rehm draw attention to the fact that within the academic field of construction heritage, little research has been done to review historical patents for possible sustainable construction materials and methods left by the wayside in the pursuit of industr

Abstract:

PVDF polymer is well known with its high strength, toughness and piezoelectric properties. It is commonly used in film form for sensor applications, mechanical actuators, energy harvesters, artificial muscles, and membranes. PVDF polymer is also used as hollow fiber membranes in filtration applications, such as nanofiber-web produced using electrospinning and as solid PVDF fiber produced using melt spinning for research purposes. According to a literature study, research on PVDF solid fiber production using wet spinning is limited. This article is about the optimization of the process paramete

Abstract:

The aim of this paper is to determine the mechanical properties of textile reinforcements laminated composite material and to establish the influence of thickness about these properties. The composite material used for this is a laminated sheet of HGW 2082. In order to study the mechanical behaviour of these kinds of materials we select two experimental tests: uniaxial test and bending test. For the uniaxial test we have measured the maximum load, the maximum extension, the maximum tensile stress and the maximum tensile strain. Also, using an optical extensometer we measured the major and the

Abstract:

Here we draw attention to the development of smart materials with embedded vasculatures that provide multiple functionality: volumetric cooling, self-healing, mechanical strength, etc. Vascularization is achieved by using tree-shaped (dendritic) and grid-shaped flow architectures. As length scales become smaller, dendritic vascularization provides dramatically superior volumetric bathing and transport properties than the use of bundles of parallel microchannels. Embedded grids of channels provide substantially better volumetric bathing when the channels have multiple diameters that are selecte
