Abstract:

The development of the production of knitwear will lead to the further application of new technologies and the expansion of the range of knitwear. In the fields of trade industry, as well as in the service sector, the main requirement is the production of knitwear, which is combined with high manufacturability and wide distribution, which will lead to low cost, with relatively acceptable consumer characteristics and parameters. In this regard, the solution to the above problems in the technological part of the production of knitwear is of particular importance and is necessary. The article exp

The obtaining of graphene directly on SiC substrates by a single step thermal decomposition process is promising, but optimal standardized conditions are not established.

Flat raft unit with high coefficient of raft section density is improved, characterizing in that it frames are fixed with oblique angles and screws, and after assembling it may be wrapped with flexible waterproof material. This gives shallow draft and stable buoyancy to the raft unit, because there is no water saturation of wood over time, and the space between the wood is not filled with a liquid that provides additional buoyancy.

Additionally, laboratory experiments were conducted using sediments on a tidal flat containing macrobenthos to examine the possibility of hydrogen sulfide formation in tidal flats. The bottom layer at the offshore station was intermittently hypoxic, and the station of the tidal flat was occa

Abstract:

We propose a novel mechanism of flat band formation based on the relative biasing of only one sublattice against other sublattices in a honeycomb lattice bilayer. The mechanism allows modification of the band dispersion from parabolic to “Mexican hat”–like through the formation of a flattened band. The mechanism is well applicable for bilayer graphene—both doped and undoped. By angle-resolved photoemission from bilayer graphene on SiC, we demonstrate the possibility of realizing this extremely flattened band (< 2-meV dispersion), which extends two-dimensionally in a k-space area around the

The physical meaning of the ABC lies in their fulfillment by the desired solution at the boundary points, which is equivalent to satisfying the original differential equation at these points.

Abstract:

Abstract The ‘DAP’ Field is one of the oil and gas fields within the Central Sumatera Basin that is proven to have hydrocarbon reserves. One of the proven reservoirs in the ‘DAP’ Field is the ‘Perahu’ Sand, Bekasap Formation. This study aims to determine the depositional environment and facies distribution focusing on the ‘Perahu’ Sand, Bekasap Formation through a sequence stratigraphic approach. The research was based on an integrated analysis of sedimentary facies from one core data and a key well log to interpret the facies association. Then the key well is correlated to eight other well lo

Abstract:

A 33MnCrTiB is a high-strength low alloy steel used for a forklift truck. This study investigates the root causes of the edge cracks in 33MnCrTiB steel produced by a steel manufacturer. After sampling, inspecting and analyzing the 33MnCrTiB flat steel with edge cracks taken from the plant, it was found that the crack and porosity contain similar residues to the deoxidation products and continuous casting mold flux. It can be concluded that the edge surface cracking in the flat steel are mainly caused by the non-deformable inclusions in steel, slag sticking and surface cracks on the original bi

Abstract:

We study the effects of surface stress on the dynamics of a solid interface which evolves by surface diffusion. In the absence of surface stress, it is known that a flat interface is unstable for long wavelength perturbations and that in the nonlinear regime this instability develops into the formation of a sharp cusp. We compute the stability spectrum for a circular pore and for a flat interface considering the surface stress contribution, and analyze its effect on the process of formation of the cusp. Analyzing the length scales involved in the problem, we show that, within the context of co

Abstract:

The Middle-Upper Cambrian Waterfowl Formation of the southern Canadian Rocky Mountains comprises (1) subtidal shelf facies, (2) ooid-peloid shoal facies, (3) outer-shelf tidal flat facies, (4) inner-shelf tidal flat facies, and (5) siliciclastic playa-mudflat facies. These facies are arranged in a deepening to shallowing to deepening pattern, representing one complete third-order cycle and the beginning of another. The Basic program MAPS was modified to model the facies of the Waterfowl Formation. Two examples are given: (1) a high-amplitude, oscillatory relative sea-level regime; and (2) a lo

Abstract:

Water entry slamming is a complicated issue in marine engineering, characterized by significant impact loads and complex flow. This paper establishes a 3D numerical model of flat plate water entry slamming based on smoothed particle hydrodynamics (SPH), and the dynamics and flow field evolution are analyzed during water entry. The results indicate that SPH effectively captures the key dynamic characteristics of flat plate water entry. The experimental data validate the model, and the SPH particles reproduce the phenomena of jet formation, cavity development, and fluid splashing. The observed p

Abstract: The article presents a graphical interpretation of the magnetic field in the return cores of a triangular cable and flat formation current line, using the commercial software Ansoft Maxwell. In the aspect of the discussed issue, the determination of the magnetic field distribution in the triangular formation (TF) determines the correct description of the correlated secondary phenomena, which include, among others, thermal or mechanical stresses, intensifying the aging process and the occurrence of losses in the transmission of electricity.
