This study aims to understand the effect of decarburization on microcrack formation rails by an onsite (laying) test. Test pieces with and without were compared under same test conditions. The results show that affects microcracks plastic flow. Furthermore, we investigated using taken from actual tracks. A comparison a decarburized layer showed crack density unground was 2.7-5.7 times higher th...

Salinity stress is one of the main factors that limit seed germination and plant growth. Therefore, magnetic water was used because it had a positive effect on germination. This study conducted to investigate (MT1, MT2, MT3, MT4, MT5) treatment passing through magnets 1, 2, 3, 5, 8 times respectively, non-magnetic (NMT) cucumber seeds (Cucumis sativus L.) under salinity (NaCl) (S1 = 0.38 dSm-1,...

determination of the starter torque-speed diagram is a major task in the design or selection of a proper gas turbine starter. in this paper, the maximum power of the mgt-40 gas turbine starter was calculated based on the dynamics of the rotor, start-up logic, and compressor map. in a recent research, the pressure ratio was assumed as a linear function of the rotor speed and the required starter...

Phytotoxic activity of Ocimum tenuiflorum (Lamiaceae) plant extracts was investigated against the germination and seedling growth of cress (Lepidium sativum), lettuce (Lactuca sativa), alfalfa (Medicago sativa), Italian ryegrass (Lolium multiflorum), barnyard grass (Echinochloa crus-galli), and timothy (Phleum pratense) at four different concentrations. The plant extracts at concentrations grea...

<p style='text-indent:20px;'>The Jordan–Moore–Gibson–Thompson (JMGT) equation is a well-established and recently widely studied model for nonlinear acoustics (NLA). It third–order (in time) semilinear Partial Differential Equation (PDE) with distinctive feature of predicting the propagation ultrasound waves at <i>finite</i> speed. This due to heat phenomenon known as <i>...
