Analysis of Torsional Vibration Characteristics of PDC Bit and Design of the Damping Tool

open access: yesShiyou jixie, 2017
In order to suppress the torsional vibration of the PDC bit, the torsion model of PDC bit was established.The force on the PDC cutter during rock breaking was analyzed to attain the relationship between WOB and torque.

DRILLING BIT PDC PLATES LIFETIME CONTROL

open access: yesИзвестия Томского политехнического университета: Инжиниринг георесурсов, 2021
The relevance of the research is caused by the fact that nowadays it will be impossible to explore the georesources if we don’t provide the drilling operations. A great part of the drilling operation is provided with the aid of PDC-bits that beyond that are used for drilling for oil and gas follow-up production.

Gel‐Amin for Improving Extracellular Recordings of Cardiomyocytes in a 3D Microphysiological System

open access: yesAdvanced Electronic Materials, EarlyView.
This work combines a conductive collagen‐based hydrogel with a laser‐cut and assembly technique to fabricate microphysiological systems that improve extracellular recordings of cardiomyocytes in 3D on microelectrode arrays. The inclusion of choline acrylate into GelMA imparts a higher electrical conductivity and improves the signal‐to‐noise ratio of on‐

Identification of histone deacetylase inhibitor targeting type I interferon and B‐cell abnormalities in systemic lupus erythematosus

open access: yesArthritis &Rheumatology, Accepted Article.
Objective Systemic lupus erythematosus (SLE) is characterized by increased type I interferon (IFN‐I) and autoantibody production. This study aimed to identify drugs that can inhibit both IFN‐I and autoantibody production. Methods We identified an inhibitor of IFN‐I production from a chemical library.

Comparison of different strategies to measure medication adherence via claims data in patients with chronic heart failure [PDF]

open access: yes, 2019
Medication adherence correlates with morbidity and mortality in patients with chronic heart failure (CHF), but is difficult to assess. We conducted a retrospective methodological cohort study in 3,808 CHF patients, calculating adherence as proportion of ...
