Discovery and engineering of an aldehyde tolerant 2-deoxy-d-ribose 5-phosphate aldolase (Dera) from pectobacterium atrosepticum
(MDPI, 2020-08)
DERA (2-Deoxy-D-ribose 5-phosphate aldolase) is the only known aldolase that accepts two aldehyde substrates, which makes it an attractive catalyst for the synthesis of a chiral polyol motif that is present in several ...
Tolerancia al aluminio en especies vegetales: mecanismos y genes
Agricultural production in the Colombian Orinoco is affected by the high aluminum content found in 4.5 million hectares. Genotypes of different species have acquired different levels of tolerance and signaling pathways ...
On the Design and Analysis of Fair Contact Plans in Predictable Delay-Tolerant Networks
(Institute of Electrical and Electronics Engineers, 2014-11)
Delay-tolerant networks (DTNs) have become a promising architecture for wireless sensor systems in challenged communication environments where traditional solutions based on persistent connectivity either fail or show ...

(Universidade Tecnológica Federal do ParanáGuarapuavaBrasilEngenharia MecânicaUTFPR, 2019-07-05)
This research investigated the behavior of two commercial steel drills - Dormer A100 standard edging steam-annealed and Dormer A002 cross-edged coated with TiN - in the drilling of an advanced high strength steel (AHSS), ...
Estudo sobre a utilização de dispositivos de fixação para usinagem fabricados pela tecnologia de modelagem por fusão e deposição
(Universidade Tecnológica Federal do ParanáGuarapuavaBrasilEngenharia MecânicaUTFPR, 2022-06-07)
Fixtures are commonly used in the manufacturing of complex parts, or in series production, but add cost and complexity to the process because they may require complex geometries and, therefore, demand machine time and ...
Reliability-based selection of manufacturing tolerance of journal bearings by means of adaptive kriging metamodel
(Universidad de Chile, 2021)
Uncertainties are present in any engineering system, from the modeling and design up to the manufacturing and performance. The performance of a system based on nominal design parameters may significantly differ from that ...
