Design and Exploitation Problems of Drill String in Directional Drilling

Acta Montanistica Slovaca, 2004
Drill string design for directional drilling requires accounting for a number of factors. First, types and expected values of loads should be determined. Then, elements of the drill string should be so selected as to enable realization of the plan at specified loads. Some of additional factors, e. g.

Labelling, Defining and Classifying the Active Ingredients in Oral Language Interventions for Children With or at Risk of Developmental Language Disorder: A Systematic Review and Qualitative Synthesis

International Journal of Language &Communication Disorders, Volume 61, Issue 4, July/August 2026.
ABSTRACT Background In recent years, there has been an increase in studies reporting on effective child language interventions for people with or at risk for (Developmental) Language Disorder ((D)LD). However, the translation of this evidence into practice has been impeded by under‐specified intervention reporting, specifically on what the active ...
