Krah, Alexander (author), Vogelaar, Timothy (author), de Jong, S.I. (author), Claridge, Jolyon K. (author), Bond, Peter J. (author), McMillan, D.G.G. (author)It is a conjecture that the ε subunit regulates ATP hydrolytic function of the F1Fo ATP synthase in bacteria. This has been proposed by the ε subunit taking an extended conformation, with a terminal helix probing into the central architecture of the hexameric catalytic domain, preventing ATP hydrolysis. The ε subunit takes a contracted...journal article 2023

Medeiros, R.P. (author), Costa, F.B. (author), Silva, K.M. (author), de Jesus Chavez, Jose (author), Popov, M. (author), Lima Junior, J.R. (author)Phasor-based differential protection is widely used as the main protection function of the power transformer due to its reliability and ability to discriminate internal from external faults and inrush currents. However, these methods present some delays due to phasor convergence during the fault occurrence and can fail during challenging...journal article 2022

Consorti Bussamra, B. (author)Targeting to improve the utilization of lignocellulosic residues in the ethanol processing industry, this work aimed to test if the product inhibition of the enzymatic hydrolysis could be relieved by extractive reaction using aqueous two-phase systems (ATPS). The performance of enzymatic hydrolysis in ATPS is not well defined in literature. In...doctoral thesis 2021

KOUROS, Michail (author)To ensure a safe power system which operates correctly, a proper grounding system is necessary to provide connections to the ground at specific points. A grounding system is generally designed: (1) to reduce voltages occurring in the grounding system for short circuit situations (at power frequency) to an acceptable level in terms of step and...master thesis 2020

Henderson, Ryan K. (author), de Valk, Sophie C. (author), Poolman, Bert (author), Mans, R. (author)Proton coupled transport of α-glucosides via Mal11 into Saccharomyces cerevisiae costs one ATP per imported molecule. Targeted mutation of all three acidic residues in the active site resulted in sugar uniport, but expression of these mutant transporters in yeast did not enable growth on sucrose. We then isolated six unique transporter...journal article 2020

(author)The enzymatic conversion of lignocellulosic material to sugars can provide a carbon source for the production of energy (fuels) and a wide range of renewable products. However, the efficiency of this conversion is impaired due to product (sugar) inhibition. Even though several studies investigate how to overcome this challenge, concepts on...journal article 2020

(author), Schippers, Jan C. (author), Kennedy, M.D. (author)A direct method for measuring adenosine-triphosphate (ATP) in seawater was developed recently, in which commercial reagents are added directly to seawater. However, calibration is required if seawater quality changes (such as changes in salinity, pH, Mg<sup>2+</sup>, Fe<sup>3+</sup>) as the seawater matrix interferes with ATP measurement. In...journal article 2019

(author)Aqueous two-phase systems (ATPS) can be applied to enzymatic reactions that are affected by product inhibition. In the biorefinery context, sugars inhibit the cellulolytic enzymes in charge of converting the biomass. Here, we present a strategy to select an ATPS (formed by polymer and salt) that can separate sugar and enzymes. This automated...journal article 2019

(author)Anaerobic industrial fermentation processes do not require aeration and intensive mixing and the accompanying cost savings are beneficial for production of chemicals and fuels. However, the free-energy conservation of fermentative pathways is often insufficient for the production and export of the desired compounds and/or for cellular growth...journal article 2018

Krah, Alexander (author), Zarco-Zavala, Mariel (author), McMillan, D.G.G. (author)ATP synthases catalyse the formation of ATP, the most common chemical energy storage unit found in living cells. These enzymes are driven by an electrochemical ion gradient, which allows the catalytic evolution of ATP by a binding change mechanism. Most ATP synthases are capable of catalysing ATP hydrolysis to varying degrees, and to prevent...review 2018

Agbemuko, Adedotun (author), van Meurs, Johannes (author), van Driel, W.D. (author)This chapter gives an extensive overview into the nature of the environment that luminaires and thus LEDs are subjected to during the event of a lightning stroke. Direct lightning stroke almost always results in instant damage for low-voltage connected devices, except in “extraordinary circumstances” where random components may survive. This is...book chapter 2018

Dedi Mahendra, Dedi (author)As the primary protection of high voltage (HV) and Extra high voltage (EHV) transmission networks, distance protection needs to operate properly under all possible fault conditions. It needs to operate as fast as possible for internal fault, while it also must be able to discriminate between the internal and the external faults to prevent...master thesis 2017
