ObjectiveTo improve the rock-breaking efficiency and durability of drill bits in the theoretical research on the optimal design of drill bits, the key is to systematically reveal both the rock-breaking mechanisms of poly...

Nonradiating sources of energy realized under a wave scattering on high-index dielectric nanoparticles have attracted a lot of attention in nano-optics and nanophotonics. They do not emit energy to the far-field, but si...

Questions: (1) Can above-ground net primary production (ANPP) of Patagonian meadows be estimated from remote sensing? (2) How does ANPP of Patagonian meadows change in space and time? Location: Northwestern Patagonia, me...

We analysed the main plant strategies to conserve nitrogen in the Patagonian Monte. We hypothesized that the two main plant functional groups (xerophytic evergreen shrubs and mesophytic perennial grasses) display differe...

Providing feed is a major input cost in beef production, hence improvements in the efficiency of feed utilisation will reduce the cost of production. Residual feed intake (RFI) is a measure of feed efficiency, and is def...

The spinning metering pump serves as a critical component that delivers the spinning solution with high precision and directly governs the efficiency of wet spinning industrialization. Nevertheless, manual adjustment of ...

ABSTRACT We investigated the effects of corn grain, finely or coarsely ground, rehydrated and ensiled to 35% moisture in substitution of dry corn grain on performance of beef cattle in the feedlot. Forty non-castrated yo...

The efficiency and longevity of photovoltaic (PV) systems are fundamentally constrained by excessive operating temperatures, which reduce electrical output and accelerate material degradation. To address this issue, this...

Abstract This paper investigates a massive MIMO–NOMA system in which the base station (BS) employs a large antenna array with low-resolution (1–2-bit) spatial Sigma–Delta (ΣΔ) ADCs to shape and suppress quantizat...

Abstract Conventional farming practices are energy-intensive and contribute significantly to greenhouse gas emissions making low-carbon agricultural production essential for India’s net-zero transition. This study asse...

A regional raw clay was used as the starting material to prepare iron-pillared clays with different iron contents. The catalytic activity of these materials was tested in the heterogeneous photo-Fenton process, applied t...

In this work four nonplanar wing configurations were studied using the vortex-lattice method: the wing-winglet, the C-wing, the biplane, and the box wing. It has been shown that linear twist, which is more practical in a...

ABSTRACT The limitations of traditional direct current–electrocoagulation (DC–EC) in wastewater treatment encompass electrode passivation, high energy consumption and substantial sludge generation. Alternating curren...

Abstract Ultra-short-wave wireless parameter distribution is one of the important means of parameter distribution in mobile communication systems. Compared with manual parameter distribution, it can significantly reduce ...

Abstract The adoption of Electric Vehicles (EVs) has accelerated due to ongoing technological advancements, cost reductions, and a growing awareness of environmental issues. However, despite this progress, challenges per...

Introduction. Self-excited induction generators (SEIGs) play a vital role in renewable energy systems, particularly in remote regions. However, their performance is highly sensitive to excitation capacitance, rotor speed...

Avaliaram-se os efeitos de diferentes porcentagens (0, 10, 20 e 30%) de inclusão da torta de macaúba (TM) no comportamento ingestivo de 24 cordeiros Santa Inês, com média de cinco meses de idade e peso vivo de 23,9kg...

The article is devoted to the issue of economic justification for management decisions on tax planning at Ukrainian enterprises. The research objective is to elaborate an approach to comparative analysis of tax alternati...

The availability of quality water is crucial for human survival. This study aims to evaluate the efficiency of reducing water colour through the upflow filtration method with variations in silica sand filter media and ba...

Reconstructing the early spatiotemporal dynamics of emerging infectious diseases (EIDs) is essential for effective public health response but remains difficult due to reporting delays, heterogeneous surveillance systems,...

The porous electrodes used in the EC treatment of emulsified oil wastewater were designed, and a study of the synergistic electro-flotation mechanism in this process was conducted using COMSOL Multiphysics simulation sof...

Ray tracing is an important computational method in electromagnetism. To improve the efficiency of electromagnetic simulation, spatial division structures such as the Bounding Volume Hierarchy (BVH) are often used to acc...

Abstract Similar to any telecommunication network, energy efficiency is a desirable feature for fiber wireless (FiWi) access networks. These networks have optical back end and wireless front end. Both ends may contribute...

Color centers in silicon have recently gained considerable attention as single-photon sources and as spin qubit-photon interfaces. However, one of the major bottlenecks to the application of silicon color centers is thei...
