Influence of Structural Parameters of Arc GrooveK-wire on Bone Drilling

open access: yesJournal of Harbin University of Science and Technology, 2020
In orthopaedic surgery,bone drilling over 55 C will lead to bone tissue necrosis and even oxidation,affecting the effect of surgery. The drilling temperature can be effectively reduced by designing micro-structures such as chip grooves on the tip surface.

Performance analysis of a low-power-consumption electric arc welding machine constructed using cost effective materials [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2023
Electric arc welding is a widely used fusion welding method. Electric power is supplied to the primary winding of the transformer as the input, and due to induction, it is transferred to the secondary winding from which it will be utilized for welding.

The Redshift Distribution of Giant Arcs in the Sloan Giant Arcs Survey

open access: yes, 2011
We measure the redshift distribution of a sample of 28 giant arcs discovered as a part of the Sloan Giant Arcs Survey (SGAS). Gemini/GMOS-North spectroscopy provides precise redshifts for 24 arcs, and "redshift desert" constraints for the remaining four.

On significance of VLBI/Gaia position offsets

open access: yes, 2017
We have cross matched the Gaia Data Release 1 secondary dataset that contains positions of 1.14 billion objects against the most complete to date catalogue of VLBI positions of 11.4 thousand sources, almost exclusively active galactic nuclei.

Site Selective Antibody-Oligonucleotide Conjugation via Microbial Transglutaminase. [PDF]

open access: yes, 2019
Nucleic Acid Therapeutics (NATs), including siRNAs and AntiSense Oligonucleotides (ASOs), have great potential to drug the undruggable genome. Targeting siRNAs and ASOs to specific cell types of interest has driven dramatic improvement in efficacy and ...

Detrital-zircon geochronology and provenance of the Ocloyic synorogenic clastic wedge, and Ordovician accretion of the Argentine Precordillera terrane [PDF]

open access: yes, 2015
The Precordillera terrane in northwestern Argentina is interpreted to be anexotic (Laurentian) continental fragment that was accreted to western Gondwanaduring the Ordovician. One prominent manifestation of the subductionand collision process is a Middle?

Influence of Different Compensation Modes on Morphological and Electrical Characteristics of Secondary Arcs

open access: yesCSEE Journal of Power and Energy Systems
UHV transmission lines are usually equipped with high-voltage shunt reactors. These reactors and the resulting degree of compensation affect the voltage, current, and other electrical characteristics of secondary arcs.

The seismotectonic regime in Greece

open access: yesAnnals of Geophysics, 1967
Evidence is presented which favours the theory that the<br />earthquake activity in the area of Greece should bo ascribed to horizontal currents flowing off to the side of the secondary sedimentary arc, from a minor mantle current rising under the ...

Radioactive Ion Sources

open access: yes, 2014
This chapter provides an overview of the basic requirements for ion sources designed and operated in radioactive ion beam facilities. The facilities where these sources are operated exploit the isotope separation online (ISOL) technique, in which a ...

Activity-regulated cytoskeleton-associated protein/activity-regulated gene 3.1 (Arc/Arg3.1) enhances dendritic cell vaccination in experimental melanoma

open access: yesOncoImmunology, 2021
Dendritic cell (DC) vaccination has proven to be an effective and safe adjuvant for cancer immunotherapies. As the presence of DCs within the tumor microenvironment promotes adaptive antitumor immunity, enhancement of DC migration toward the tumor ...
