Yield at Thermal Engines Internal Combustion [PDF]
American Journal of Engineering and Applied Sciences, 2017 The paper presents an algorithm to set the parameters of the dynamics of the classic mechanism the main of internal combustion. It shows the distribution of the forces (on the main mechanism of the engine) on engines with internal combustion. With these strong points and together with speeds of kinematic couplings shall be determined when the output of

The Yield of the Thermal Engines [PDF]
Journal of Mechatronics and Robotics, 2019 This paper presents an algorithm for determining the dynamic parameters of the main classic mechanism of internal combustion engines. It shows the distribution of forces (on the main engine mechanism) to internal combustion engines. With these forces and together with the kinematic coupling speeds, the efficiency of the thermal engine is determined ...

Pathway engineering for high-yield production of lutein in Escherichia coli [PDF]
Synthetic Biology, 2021 Abstract Lutein is an industrially important carotenoid pigment, which is essential for photoprotection and photosynthesis in plants. Lutein is crucial for maintaining human health due to its protective ability from ocular diseases. However, its pathway engineering research has scarcely been performed for microbial production using ...

Effects of GaN Buffer Resistance on the Device Performances of AlGaN/GaN HEMTs
Crystals, 2020 We investigated the effects of GaN buffer resistance of AlGaN/GaN high-electron-mobility transistors (HEMTs) on direct current (DC), low-frequency noise (LFN), and pulsed I-V characterization performances.

Estimation of Crop Yield Distribution: Implication for Crop Engineering Risk
Systems Engineering Procedia, 2012 AbstractIn this paper we use parametric and nonparametric density estimation procedures to evaluate crop yield distributions in Yunnan province. Akaike Information Criterion (AIC) is used to select a proper crop yield distribution. Maximum likelihood methods are explored to obtain reliable estimates.

The metabolic engineering of Escherichia coli for the high-yield production of hypoxanthine [PDF]
Microbial Cell FactoriesHypoxanthine, prevalent in animals and plants, is used in the production of food additives, nucleoside antiviral drugs, and disease diagnosis. Current biological fermentation methods synthesize quantities insufficient to meet industrial demands. Therefore, this study aimed to develop a strain capable of industrial-scale production of hypoxanthine.De ...

Low-Frequency Noise Behavior of AlGaN/GaN HEMTs with Different Al Compositions
Crystals, 2020 AlxGa1−xN/GaN heterostructures with two kinds of Al composition were grown by metal organic chemical vapor deposition (MOCVD) on sapphire substrates. The Al compositions in the AlGaN barrier layer were confirmed to be 13% and 28% using high resolution X ...
