Thermally efficient compact fluorescent fixtures [PDF]

Conference Record of the 1990 IEEE Industry Applications Society Annual Meeting, 2002
A series of prototype fixtures that employ convective venting and heat sinking to reduce elevated lamp temperatures is described. Experimental data show that decreases in fixture efficiency can approach 20% due to elevated temperature conditions inside the lamp compartment.

Burn threshold prediction for high efficiency deep grinding [PDF]

, 2006
Burn threshold diagrams are useful for the prediction of thermally induced grinding damage and were originally developed to describe the conventional shallow cut grinding regime.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Influence of usage and model inaccuracies on the performance of smart hot water heaters: lessons learned from a demand response field test

Frontiers in Energy Research
Domestic hot water heaters are considered to be easily integrated as flexible loads for demand response. While literature grows on reproducible simulation and lab tests, real-world implementation in field tests considering state estimation and demand ...

Efficient quantum thermal simulation

Nature
Abstract Quantum computers promise to tackle quantum simulation problems that are classically intractable 1 . Although a lot of quantum algorithms 2–4 have been developed for simulating quantum dynamics, a general-purpose method for ...

Investigation of the thermal efficiencies of a solar dryer

Energy Conversion and Management, 1995
Abstract This paper deals with the construction and performance of a solar powered drying system consisting of a solar air heater and a drying chamber. The thermal efficiencies of both the solar air heater and the drying section as a function of typical physical parameters and the experimental results for different food products at different air flow

Thermal Modelling and Simulation of Parabolic Trough Receiver Tubes [PDF]

, 2010
Receiver tubes (or heat collecting elements — HCE) are a key component of parabolic trough solar thermal power plants. They are mounted in the focal line of the collectors, absorb the concentrated solar irradiance and transfer the absorbed energy to the ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...
