“I'm not in love, so don't forget it; it's just a silly phase I'm going through”: On (not) falling in love during fieldwork in Southwest China

open access: yesAnthropology and Humanism, Volume 51, Issue 2, December 2026.
Abstract During fieldwork, anthropologists engage in emotional, social and economic exchanges with interlocutors, through which to better understand one's own positionality and that of others. When such exchanges occur with an interlocutor who becomes a romantic lover, these exchanges are filtered through desire, amplifying their psychological ...

Study on Dynamic Characteristics of drill String-drill Bit-rock System

open access: yesShiyou jixie, 2017
Drill bit, drill string and rock system as a whole, has coupled and interacted dynamic characteristics, which is neglected in most of researches. In view of this, considering the coupling of axial and lateral torsion of the lower drilling tool and the ...

Experimental methods in chemical engineering: Cyclic voltammetry—CV

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 11, Page 5776-5827, November 2026.
Abstract Cyclic voltammetry (CV) is a foundational electroanalytical technique for investigating redox behaviour and evaluating material performance across fields such as molecular electrochemistry, electrocatalysis, sensing, and energy storage. Despite its widespread use, a gap remains between formal electrochemical theory and the practical data ...

Feminist Temporalities of Agrarian‐Climate Crises: Synchronisation and the Afterlives of Speculation in India

open access: yesAntipode, Volume 58, Issue 6, November 2026.
ABSTRACT This paper brings a feminist temporal perspective to understandings of agrarian‐climate crises in monsoon‐dependent regions of India, examining how time operates as a site of material struggle and social differentiation. Drawing on ethnographic research in Vidarbha, it explores how farmers synchronise diverse temporalities to navigate ...

Optimal bit selection for large-diameter wellbore drilling in an ultra-deep well

open access: yesPetroleum Exploration and Development
To optimize the bit selection for large-diameter wellbore in the upper section of an ultra-deep well S-1, a full-well dynamic model integrating drill string vibration and bit rock-breaking was established and then verified using measured vibration data ...

The effectiveness of implementation intentions in children: A systematic review and meta‐analysis

open access: yesBritish Journal of Psychology, Volume 117, Issue 4, Page 1711-1758, November 2026.
Abstract Self‐regulation abilities in childhood are important for long‐term academic achievement and healthy development. As self‐regulatory abilities are still developing, ‘simple’ interventions are needed to foster self‐regulation. Implementation intentions are simple plans that could promote goal achievement in children.

EFFECT OF PDC BIT WEAR AND OPERATING PARAMETERS ON OIL-WELL DRILL-STRING DYNAMICS [PDF]

open access: yes, 2015
Drill-string vibrations reduces the drilling performance, the bit wear negative effects on the drill-string dynamics is one of the elements which limit reaching the optimum drilling performance due to vibrations caused by the bit wear and other factors ...

Drill String Dynamics in Deepwater Open-Loop Drilling of an Ultra-Shallow High-Build-Rate Horizontal Well

open access: yesJournal of Marine Science and Engineering
In deepwater open-loop drilling of ultra-shallow high-build-rate horizontal wells, the drill string spans the exposed seawater section, the mudline transition, and the constrained downhole section.
