Primary cultures of chick osteocytes retain functional gap junctions between osteocytes and between osteocytes and osteoblasts [PDF]

open access: yes, 2008
The inaccessibility of osteocytes due to their embedment in the calcified bone matrix in vivo has precluded direct demonstration that osteocytes use gap junctions as a means of intercellular communication.

Modelling follow up time at a single-lane roundabout

open access: yesJournal of Traffic and Transportation Engineering (English ed. Online), 2014
The follow up time is an important parameter for estimating the entry capacity of roundabouts. However, its variability and contributing factors have long been ignored in the literatures.

Minding the Gap: Comparing Student and Instructor Experiences with Critical Reflection

open access: yesTeaching & Learning Inquiry: The ISSOTL Journal, 2021
Critical reflection (CR) is regarded as essential for learning in higher education. Many instructors want students to reflect deeply and critically, but lament perceived deficiencies in students’ value and understanding of CR.

Bridging the gap between educational research and educational practice: The need for critical distance [PDF]

open access: yes, 2007
The contributions to this special issue explore a range of different aspects of the relationship between research and practice in education. All start from the assumption that there is a gap between research and practice.

The Contribution to the Procedure of Capacity Determination at Unsignalized Priority-controlled Intersections

open access: yesPromet (Zagreb), 2004
The problem of minor vehicles crossing or merging into themajor stream at unsignalized priority-controlled intersections iswell-known. Numerous solutions involve various assumptionsconcerning the major headway distributions, number of majorlanes ...

Influence of multiple islands on the hysteresis and dynamics of a western boundary current perturbed by a mesoscale eddy at a gap

open access: yesFrontiers in Marine Science, 2023
The hysteresis of a western boundary current (WBC) flowing across a gap and the dynamics of the mesoscale eddy–WBC interaction with the presence of two islands in the gap are studied using a 1.5-layer ocean model.

Analyzing variations in spatial critical gaps at two-way stop controlled intersections using parametric and non-parametric techniques

open access: yesJournal of Traffic and Transportation Engineering (English ed. Online), 2021
At two-way stop controlled (TWSC) intersections drivers on minor stream are generally at risk because of the difficulty in judging safe gap between major stream vehicles.
