An overview of biodiesel energy [PDF]

, 2020
Over the last ten years’ attention to biofuels production has increased dramatically and become crucial. One of the main factors is the rise in world oil prices, coupled with the abatement of greenhouse gas emissions and concerns about energy security ...

Analysis of the service life of wooden bridge structures using structural protection

Case Studies in Construction Materials
This article deals with the use of polyurea contact insulator as structural protection for wooden bridge structures. The waterproof coating is applied to a spruce wood substrate to create a composite element with a protective layer to protect the wood ...

Risk assessment of desert pollution on composite high voltage insulators

Journal of Advanced Research, 2014
Transmission lines located in the desert are subjected to desert climate, one of whose features is sandstorms. With long accumulation of sand and with the advent of moisture from rain, ambient humidity and dew, a conductive layer forms and the subsequent

Superfluid and Mott Insulator phases of one-dimensional Bose-Fermi mixtures [PDF]

, 2008
We study the ground state phases of Bose-Fermi mixtures in one-dimensional optical lattices with quantum Monte Carlo simulations using the Canonical Worm algorithm. Depending on the filling of bosons and fermions, and the on-site intra- and inter-species

Cis‐regulatory and long noncoding RNA alterations in breast cancer – current insights, biomarker utility, and the critical need for functional validation

Molecular Oncology, EarlyView.
The noncoding region of the genome plays a key role in regulating gene expression, and mutations within these regions are capable of altering it. Researchers have identified multiple functional noncoding mutations associated with increased cancer risk in the genome of breast cancer patients.

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

Molecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Interaction and filling induced quantum phases of dual Mott insulators of bosons and fermions

, 2010
Many-body effects are at the very heart of diverse phenomena found in condensed-matter physics. One striking example is the Mott insulator phase where conductivity is suppressed as a result of a strong repulsive interaction. Advances in cold atom physics

Dog Wool Microparticles/Polyurethane Composite for Thermal Insulation [PDF]

Polymers, 2020
A polyurethane (PU)-based eco-composite foam was prepared using dog wool fibers as a filler. Fibers were acquired from pet shops and alkaline treated prior to use. The influence of their incorporation on the PU foams’ morphological, thermal, and mechanical properties was investigated.
