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

open access: yesFEBS 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.

EXPERIMENTAL AND NUMERICAL INVESTIGATION OF SMALL AXIAL TURBINES

open access: yesTASK Quarterly, 2010
The authors conducted a series of experimental studies using a flow tunnel to determine the hydrodynamic characteristics of small axial turbines. The results obtained were confronted with the results obtained from the authors’ own numerical codes based ...

A Variable Data Fusion Approach for Electromechanical Impedance-Based Damage Detection

open access: yesSensors, 2020
There is continuing research in the area of structural health monitoring (SHM) as it may allow a reduction in maintenance costs as well as lifetime extension.

Probing cilia-driven flow in living embryos using femtosecond laser ablation and fast imaging [PDF]

open access: yes, 2009
Embryonic development strictly depends on fluid dynamics. As a consequence, understanding biological fluid dynamic is essential since it is unclear how flow affects development.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

NUMERICAL ANALYSIS OF HIGH-SPEED IMPULSIVE (HSI) NOISE OF PZL W3-A “SOKÓŁ” (FALCON) HELICOPTER MAIN ROTOR IN FORWARD FLIGHT

open access: yesTASK Quarterly, 2015
The paper presents the results of a numerical simulation of the flow and acoustic field generated by the PZL W3-A “Sokół” (Falcon) helicopter main rotor in high-speed forward flight conditions based on the URANS approach and the chimera overlapping ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

open access: yesFEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

open access: yesFEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

THERMO-MECHANICAL COUPLING BETWEEN THE FLOW OF STEAM AND DEFORMATION OF THE VALVE DURING START-UP OF THE 200MW TURBINE

open access: yesTASK Quarterly, 2001
The lifetime estimation of power station structures and components, subjected to fatigue loading, is essential for determining the moment of repair or replacement. Therefore the degradation behaviour and damage development within material should be very
