Performance evaluation of biodegradable metalworking fluids for machining process [PDF]

, 2017
The widely use of metalworking fluids (MWFs) petroleum-based in the industry have a negative impact to the environment and human. Thus, various initiatives have been undertaken to develop bio-based MWFs especially from crude jatropha oil (CJO).

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

FEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Measurement of Wood Cutting Forces during Bandsawing Using Piezoelectric Dynamometer

Drvna Industrija, 2016
Optimization of wood cutting conditions can decrease the cutting forces, which directly relates to the energy consumption. The aim of this study was to measure cutting force components in bandsaw processing of green oak and beech wood at 90°-90° cutting ...

Experimental study of coated carbide tools behaviour: application for Ti-5-5-5-3 turning [PDF]

, 2011
The goal of this paper is to study the relation between the input data (conditions and geometry of cut) and answers (wear of tool, forces and cutting temperatures) when machining the Ti-5-5-5-3 alloy treated. This study has shown that the cutting process

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

FEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

FRF Estimation through Sweep Milling Force Excitation (SMFE) [PDF]

, 2016
Inaccurate machine dynamics characterization is thought to be one of the main sources of errors in current cutting stability models. For this reason, traditional dynamic characterization procedures have been called into question.

Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function

FEBS Open Bio, EarlyView.
We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...

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

FEBS 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.

Simulation of the mechanical process of gypsum cutting with picks

REM: International Engineering Journal
Several research works have been done to assess the effect of the cutting depth on the cutting forces when using picks. In this case, the cutting tests need im-portant equipment to cut rocks, to register the cutting force and to determine the cutting ...
