In this paper, case study on outlet cracking is first conducted for the Goupitan and Xiaowan arch dams. A nonlinear FEM method is then implemented to study effects of the outlets on integral stability of the Xiluodu arch dam under two loading conditions, i.e., normal loading and overloading conditions. On the basis of the case study and the numerical modelling, the outlet cracking mechanism, ri...

This paper presents the heat transfer coefficients measured during HC-290 (Propane) vaporisation inside a brazed plate heat exchanger: the effects of heat flux, saturation temperature (pressure) and outlet conditions are investigated. The heat transfer coefficients show weak sensitivity to saturation temperature (pressure) and great sensitivity to heat flux and outlet conditions. The saturated ...

In this research, solar-drived integrated Hydrogen production (HP) using high-temperature steam electrolysis (HTSE) is thermodynamically evaluated. This system includes an organic Rankine cycle (ORC), Rankine cycle, Brayton cycle, solar tower, and High Temperature Steam Electrolysis (HTSE). Solar energy supplies thermal energy. This heat source is applied for generating power. This energy is us...

• Production of maximally viable B. amyloliquefaciens H57 probiotic dried powder. Understanding the inherent thermostability bacterium is key for process development. Spray drying at an optimal outlet temperature provided best cell survivability. more efficient than freeze in preserving viability. Refrigeration prolonged shelf-life and practices production Bacillus as a power feed applications ...

In situ non-intrusive measurements of water vapor partial pressure and temperature were performed simultaneously along two gas channels on he cathode side of a PEM fuel cell using tunable diode laser absorption spectroscopy. This measurement technique developed by us was utilized arlier to make measurements in a single bipolar plate channel of a prototype PEM fuel cell. The current study examin...

The 2,379,636-bp draft genome sequence of Thermus scotoductus strain K1, isolated from geothermal spring outlet located in the Karvachar region in Nagorno Karabakh is presented. Strain K1 shares about 80% genome sequence similarity with T. scotoductus strain SA-01, recovered from a deep gold mine in South Africa.

Abstract Whereas evidences of single-cell studies have suggested the cellular diversity medulloblastoma, most common malignant brain tumor in childhood, understanding spatial status for specific cell populations and gene modules remains rudimentary. Herein, we comprehensively analyze single-nucleus RNA expression, chromatin accessibility transcriptomic profiling from 52 human medulloblastomas s...

Model-based control of the outlet temperature of a distributed solar collector eld is studied. An energy-based controller is derived using internal energy as a storage function and controlled variable. The controller relies on a distributed parameter nonlinear plant model and includes feedforward from the solar irradiation and inlet temperature. Stability of the closed loop is proved, and the m...
