Standard and experimental drilling fluids’ effect on the response of the larvae of bivalve Hiatella sp. [PDF]
Behavior of the larvae of common genus of marine bivalve mollusk Hiatella sp. was tested at the presence of the standard drilling fluid and the water-based drilling fluid containing brown alga Saccharina latissima as biodegradable component.

Preliminary test on modified clays for seawater resistant drilling fluids [PDF]
The quality of a drilling fluid declines in salt water conditions. An engineered clay (HYPER clay) was developed for geosynthetic clay liners with enhanced resistance to aggressive conditions.

For the purpose of obtaining an effective emulsifier for high pH Lime-emulsion drilling fluid, the humic acid has been researched in our oaboratory, and it has been found that it is superior to other various surface active agents. In this paper the effect of the humic acid upon drilling fluid is described.

Drill fluid selection for the SUBGLACIOR probe: a review of silicone oil as a drill fluid [PDF]
AbstractAs part of the ICE&LASER/SUBGLACIOR projects, an innovative probe called SUBGLACIOR is developed with the aim of perforating the ice sheet down to depths of 3500 m in a single season and continuously measuring in situ the isotopic composition of the meltwater and the methane concentration in trapped gases.

Research of the pulsating flow of drilling fluid in the drill string
The object of research is the pulsating flow of drilling fluid in the drill string. One of the most problematic places is pressure loss due to friction forces distributed along the length of the flow and concentrated in its nodes (threaded joints and pipe bends).

Rad27/FEN1 prevents accumulation of Okazaki fragments and ribosomal DNA copy number changes
The budding yeast Rad27 is a structure‐specific endonuclease. Here, the authors reveal that Rad27 is crucial for maintaining the stability of the ribosomal RNA gene (rDNA) region. Rad27 deficiency leads to the accumulation of Okazaki fragments and changes in rDNA copy number.

Objective Foot orthoses are thought to improve pain by potentially modifying internal mechanical forces. To test this, we explored whether foot orthoses can modify patterns of bone marrow lesions (BMLs) in people with midfoot pain. Methods Forty‐two people were recruited with midfoot pain and MRI‐confirmed midfoot BMLs.
