Dry ice blasting plays an essential role in today’s cleaning industry, where many industry players have used it after realizing its advantages. The disadvantage of dry ice blasting is relatively small kinetic energy and offer less aggressive clean effect, especially for dual-hose nozzle geometry. This project was mainly to study the impact force of nozzle geometry of dry ice blasting concerning pr...... hiện toàn bộ
Parametrization of cross sections for elementary hadronic collisions involving strange particlesThe European Physical Journal Plus - Tập 133 - Trang 1-34 - 2018

The production of strange particles (kaons, hyperons) and hypernuclei in light charged-particle-induced reactions in the energy range of a few GeV (2-15 GeV) has become a topic of active research in several facilities (e.g., HypHI and PANDA at GSI and/or FAIR (Germany), JLab (USA), and JPARC (Japan)). This energy range represents the low-energy limit of the string models (degree of freedom: quark ...... hiện toàn bộ
Anisotropic strange quark stars with a non-linear equation-of-stateThe European Physical Journal Plus - Tập 134 - Trang 1-8 - 2019
Ilídio Lopes, Grigoris Panotopoulos, Ángel Rincón
We obtain an exact analytical solution to Einstein’s field equations assuming a non-linear equation-of-state and a particular mass function. Our solution describes the interior of anisotropic color flavor locked strange quark stars. All energy conditions are fulfilled, and therefore the solution obtained here is a realistic solution within General Relativity. The mass-to-radius profile is obtained...... hiện toàn bộ
Synchronization of frustrated phase oscillators in the small-world networksThe European Physical Journal Plus - Tập 137 - Trang 1-9 - 2022
Esmaeil Mahdavi, Mina Zarei, Farhad Shahbazi
We numerically study the synchronization of an identical population of Kuramoto–Sakaguchi phase oscillators in Watts–Strogatz networks. We find that, unlike random networks, phase shift could enhance the synchronization in small-world networks. We also observe abrupt phase transition with hysteresis at some values of phase shifts in small-world networks, signs of an explosive phase transition. Mor...... hiện toàn bộ
An insider view of the Portuguese ion beam laboratoryThe European Physical Journal Plus - Tập 136 - Trang 1-18 - 2021

Accelerators are behind many major scientific and technological breakthroughs giving a gigantic contribution to unveil the mysteries of matter. This quest continues nowadays using the high-energy machines operating at large research centres like CERN, GANIL and FAIR, among others. Meanwhile most of the small and medium size accelerators running in laboratories located in universities and research ...... hiện toàn bộ
Control of non-Newtonian fluid flow and heat transfer in microchannel by using porous triangular ribs and pulsating jetThe European Physical Journal Plus - Tập 137 - Trang 1-14 - 2022
Somayeh Davoodabadi Farahani, Mahdi Hosseni, Amir Zakinia, Hakan F. Öztop
In this study, the numerical exploration of heat transfer of non-Newtonian fluid in a ribbed microchannel (MCH) with a pulsating impingement jet is inspected. The coolant is CMC-Water, which is a non-Newtonian fluid. The ribs are intended to be triangular with different angles as
$$30^\circ ,40^\circ \mathrm{and} 60^\circ $$

Ma thuật của tiền và ảo tưởng về sinh liệu: hướng tới một hiểu biết liên ngành về công nghệ Dịch bởi AI The European Physical Journal Plus - Tập 132 - Trang 1-5 - 2017
Alf Hornborg
Trong nhiều thế kỷ, thế giới quan chủ đạo trong các xã hội công nghiệp đã cho rằng các vấn đề khác nhau – chẳng hạn như những vấn đề gần đây được xác định liên quan đến tính bền vững – có thể được giải quyết thông qua tiến bộ công nghệ. Tiến bộ công nghệ đã được coi là thành quả của khoa học kỹ thuật, kiến thức mới và đổi mới. Mặc dù kiến thức về các nguyên lý vật lý chắc chắn là điều kiện cần thi...... hiện toàn bộ
