Energy recovery in a commercial building using pico-hydropower turbines: An Australian case study

open access: yesHeliyon, 2023
Optimising energy use in systems and buildings is crucial to reduce climate change. This paper aims to address the gap in knowledge for pico-hydropower (

Human ES-derived MSCs correct TNF-α-mediated alterations in a blood–brain barrier model

open access: yesFluids and Barriers of the CNS, 2019
Background Immune cell trafficking into the CNS is considered to contribute to pathogenesis in MS and its animal model, EAE. Disruption of the blood–brain barrier (BBB) is a hallmark of these pathologies and a potential target of therapeutics.

Permeability Barrier and Microstructure of Skin Lipid Membrane Models of Impaired Glucosylceramide Processing

open access: yesScientific Reports, 2017
Ceramide (Cer) release from glucosylceramides (GlcCer) is critical for the formation of the skin permeability barrier. Changes in β-glucocerebrosidase (GlcCer’ase) activity lead to diminished Cer, GlcCer accumulation and structural defects in SC lipid ...

Characterizations of safety in hybrid inclusions via barrier functions [PDF]

open access: yes, 2019
This paper investigates characterizations of safety in terms of barrier functions for hybrid systems modeled by hybrid inclusions. After introducing an adequate definition of safety for hybrid inclusions, sufficient conditions using continuously ...

Origine et destination du soin medical

open access: yesOcula, 2019
Defining the user as both professional and beneficiary, I propose a systemic and participative modelling of project management. This means, in the field of medical care, that the patient is both at the beginning and at the end of the process and that he ...

Les exemples dans l’élaboration des démonstrations mathématiques : une approche sémantique et dialogique

open access: yesRecherches en Éducation, 2016
This paper addresses the roles of examples when dealing with mathematical proof in higher education. I use the distinction between semantic and syntactic approaches to get a first insight.

Epidermal Barriers [PDF]

open access: yesCold Spring Harbor Perspectives in Medicine, 2014
The epidermis functions as a physical barrier to the external environment and works to prevent loss of water from the skin. Numerous factors have been implicated in the formation of epidermal barriers, such as cornified envelopes, corneocytes, lipids, junctional proteins, proteases, protease inhibitors, antimicrobial peptides, and transcription factors.

Natural Barriers and Policy Barriers [PDF]

open access: yesSSRN Electronic Journal, 2020
This paper investigates whether "natural" trade barriers of a country due to geography and other factors outside the country's control stimulate more or less policy barriers such as tariffs. Our theory predicts that the politician's relative weight on private benefits over social welfare in a "protection-for-sale" setup depends on these "natural ...

Glutamate-mediated blood-brain barrier opening. implications for neuroprotection and drug delivery [PDF]

open access: yes, 2016
The blood-brain barrier is a highly selective anatomical and functional interface allowing a unique environment for neuro-glia networks. Blood-brain barrier dysfunction is common in most brain disorders and is associated with disease course and delayed ...

Fusion at deep subbarrier energies: potential inversion revisited [PDF]

open access: yes, 2008
For a single potential barrier, the barrier penetrability can be inverted based on the WKB approximation to yield the barrier thickness. We apply this method to heavy-ion fusion reactions at energies well below the Coulomb barrier and directly determine ...
