The Anti-Hitler Coalition: From Enmity to Military Alliance — A Formula for Success by A. Yu. Borisov

“…In order to combat these attempts it is necessary to examine once again a turbulent history of the inter-war period and, particularly, the reasons why all attempts to form a united antifascist front had failed in the 1930s, but eventually led to the formation of the anti-Hitler coalition.The paper focuses on a complex set of political considerations, including cooperation and confrontation, mutual suspicions and a fervent desire to find an ally in the face of growing international tensions, which all together determined the dynamics of relations within a strategic triangle of the Soviet Union — the United States — Great Britain in the late 1930s and early 1940s. …”

Simulation study on catalytic oxidation of low concentration mine gas in an oxidation device by Yuhang Liu, Xijian Li, Qi Xiao, Xingfa Jiang, Weilai Dong, Xianyong Chen, Yuyan Feng

“…To study the combustion and heat transfer reactions of low-concentration coal mine methane in a catalytic oxidation device, a numerical simulation approach was employed to establish a model of the catalytic oxidation device that includes periodic boundary conditions, methane combustion mechanisms, and turbulent-laminar flow characteristics. The core focus of this study is on the dynamic changes in the bed temperature of the oxidation device, the temperature of the extracted hot air, and the methane conversion rate. …”

Assessing the salinization mechanisms of coastal brackish springs by Sanz, Esteban, Carrera, Jesús, Ayora, Carlos, Barón, Alfredo, González, Concha

“…To this end, we derive the equations governing variable-density turbulent flow through the conduits. These turn out to be similar to the traditional ones, except that (1) Bernouilli’s head (energy per unit weight) is substituted by the energy per unit volume, and (2) this energy is not a potential, as a flow path dependent term needs to be added. …”

Women’s mental health in the doctoral context: Protective function of the psychological capital and academic motivation by Angel Deroncele-Acosta, Roger Pedro Norabuena-Figueroa, Emerson Damian Norabuena-Figueroa

“…Background: Science recognizes the anxieties, depression, stress, and “turbulences” that women face in doctoral studies, but women’s mental health in this context is still little addressed, even though it is a critical aspect for the well-being, persistence, and success of women doctoral candidates, who continue to be underrepresented in many professional fields. …”

Investigating the role of gravity waves in mesosphere and lower-thermosphere (MLT) inversions at low latitudes by C. Lingerew, U. J. P. Raju

“…<p>The mesosphere and lower-thermosphere (MLT) transitional region, encompassing a height range of 60–100 km, is a distinct and highly turbulent zone within Earth's atmosphere. The region is significant owing to dynamics of atmospheric processes like planetary, tidal, and particularly gravity waves, which contribute to the formation of the mesospheric inversion layer (MIL). …”

A comparative filling materials study on microstructure and mechanical properties of welded joints of dissimilar Al–Mg–Si alloys using CMT-laser beam oscillation hybrid welding by H.Y. Shen, J.M. Yu, L. Wang, F. Vogel, C.J. Li, H. Nagaumi

“…Microstructural analysis revealed a distinct layered structure on the 6061 side, contributing to a hard-soft microstructural configuration that enhances ductility, with fracture strains of 3.4% for ER4047 and 4.8% for ER5183. In this study, turbulent flow dominates over previously proposed laminar flow, but a prolonged duration for complete solute mixing is still required, leading to the persistent presence of unmixed and partially mixed zones in the liquid weld pool before solidification. …”
