Rapid screening of staphylokinase protein variants using an unpurified cell‐free expression system

open access: yesFEBS Open Bio, EarlyView.
An unpurified cell‐free protein synthesis (CFPS) platform enables rapid functional screening of staphylokinase variants. Direct plasminogen‐activation assays performed in microplate format provide real‐time activity readouts, allowing rapid identification and ranking of variants with improved or reduced fibrinolytic activity without protein ...

Circumferential pressure distributions in a model labyrinth seal [PDF]

open access: yes, 1982
A research program to isolate and study leakage flow through labyrinth glands was initiated. Circumferential pressure distributions were measured in the labyrinth glands with geometry appropriate to the high pressure labyrinths in large steam turbines ...

Large‐scale bidirectional arrayed genetic screens identify OXR1 and EMC4 as modifiers of αSynuclein aggregation

open access: yesFEBS Open Bio, EarlyView.
Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

Natural vibration frequencies of delaminated composite beams

open access: yesComputer Assisted Methods in Engineering and Science, 2023
In the presented work a model of a layered, delaminated composite beam based on the finite elements method was introduced. In this model the beam was divided into finite elements, while the delamination was modelled using additional boundary conditions.

Solar energy collection system [PDF]

open access: yes, 1979
A fixed, linear, ground-based primary reflector having an extended curved sawtooth-contoured surface covered with a metalized polymeric reflecting material, reflects solar energy to a movably supported collector that is kept at the concentrated line ...

Adaptive locomotion of artificial microswimmers

open access: yes, 2019
Bacteria can exploit mechanics to display remarkable plasticity in response to locally changing physical and chemical conditions. Compliant structures play a striking role in their taxis behavior, specifically for navigation inside complex and structured

Expander selection for an on board ORC energy recovery system [PDF]

open access: yes, 2017
This paper deals with the comparison between volumetric expanders (screw, scroll and rotary vane) and an Inlet Forward Radial (IFR) micro turbine for the exploitation of an on board Organic Rankine Cycle (ORC) energy recovery system.

Mass spectrometry based identification of AMP‐O‐Tris generated by Thermococcus onnurineus Cas10

open access: yesFEBS Open Bio, EarlyView.
Isolated Thermococcus onnurineus Cas10 generates the noncanonical ATP‐derived product AMP‐O‐Tris while in Tris‐containing buffer as identified via mass spectrometry, revealing relaxed nucleophile selectivity under isolated conditions. These findings suggest that multiprotein Csm complex assembly restricts Cas10 reactivity toward canonical cyclic ...

Why have hydrostatic bearings been avoided as a stabilizing element for rotating machines [PDF]

open access: yes
The advantages are discussed of hydrostatic, high pressure bearings as providers of higher margin of stability to the rotor/bearing systems. It is apparent that deliberate use of hydrostatic bearing high pressure lubricated (any gas or liquid) can easily

Increasing of reliability of work of rotating machines of oil and gas industry [PDF]

open access: yes, 2013
The paper proposes two ways to improve the reliability of rotating machinery of oil and gas industry through the use of rolling bearings that allow evenly distribute the pressure of lubricating fluid to the surface of the ...
