    Determination of long-term permissible currents in wires of power supply systems of railways by E. P. FIGURNOV, Yu. I. ZHARKOV, V. I. KHARCHEVNIKOV

    Published 2019-06-01
    “…This requires recalculation of previously valid values of long-term permissible currents. Authors considered revised method for calculating the long-term permissible currents, based on a more rigorous consideration of the laws of heat transfer and experimental studies of the conditions of heating and cooling of shaped (contact) and stranded wires. …”

    Thermal Load Influence during the Formation of Al-Al Contacts on the Electrical Parameters of the Integrated Circuits with Aluminum-Polysilicon Contacts by V. A. Pilipenko, V. A. Solodukha, N. S. Kovalchuk, J. A. Solovjov, D. V. Shestovski, D. V. Zhyhulin

    Published 2022-12-01
    “…An analysis of the currentvoltage characteristics showed that they are all identical, except for the course of the direct branch of the base current value from the emitter-base voltage. The deviation of the linear nature of this dependence in the region of their low voltage values (£ 200 mV) in the case of the formation of ohmic Al-Si and Al-Al contacts with the use of long-term heat treatments is due to the predominance of the generation-recombination current in this region associated with an increased density of traps in the depleted region and on the surface of the semiconductor. …”

    Ways to improve the efficiency of automatic control systems of pressing current collectors for railway service of high speeds by A. S. GOLUBKOV, O. A. SIDOROV, S. N. SMERDIN

    Published 2019-06-01
    “…With increasing operation speeds, the dynamic loads on the current collector from the rolling stock increase and the aerodynamic impact increases as well, which leads to an increase in the variation of the contact pressure, tearing off the current collector from the contact wire, arcing in contact and increased wear of the contact elements. …”

    Evaluation of Temporal Changes in Evapotranspiration and Crop Water Requirements in the Context of Changing Climate: Case Study of the Northern Bucharest–Ilfov Development Region,... by Florentina Iuliana Mincu, Daniel Constantin Diaconu, Dana Maria Oprea Constantin, Daniel Peptenatu

    Published 2025-06-01
    “…The methodology used highlights this fact, showing that major changes are needed in the choice of crop schemes and future technological processes in the current context of climate change. The current results of the study, conducted over a period of 30 years (1991–2020), showed that the climatic, land use and economic changes in the study area have led to a decrease in evapotranspiration and crop water requirements due to the amounts of precipitation that can provide for the water needs of strawberry, sunflower and pea crops. …”

    Impact of strategic public health interventions to reduce tuberculosis incidence in Brazil: a Bayesian structural time-series scenario analysisResearch in context by Klauss Villalva-Serra, Beatriz Barreto-Duarte, Moreno M. Rodrigues, Artur T.L. Queiroz, Leonardo Martinez, Julio Croda, Valeria C. Rolla, Afrânio L. Kritski, Marcelo Cordeiro-Santos, Timothy R. Sterling, Mariana Araújo-Pereira, Bruno B. Andrade

    Published 2025-01-01
    “…Additional reductions were seen with increased coverage of DOT, TPT adherence, and contact investigation rates (−14.4 [−13 to −16.2]), and by combining these with efforts to reduce TB cases among vulnerable populations (−23.6 [−26.3 to −41.4]), potentially lowering incidence to 18.5 [7.8–28.4] per 100,000, though still above WHO targets. …”
