Cohesin gets pushed around ings of cohesin hold together sister chromatids. Armelle and colleagues now suggest that cohesin rings get pushed to their final resting places by transcription complexes. Cohesins are known to bind a heterochromatin protein at centromeres, but previous reports of cohesin localization on chromosome arms were incomplete. The authors did a comprehensive survey of four b...

The measurement of power output (PO) during cycling has led some manufacturers to develop mobile power meters. However, such devices have to provide a valid, sensitive and reproducible PO. This study aimed to determine the validity, sensitivity and reproducibility of the Stages and Garmin Vector during both laboratory and field cycling tests. The results demonstrate that the Stages and the Garm...

This experimental study investigated the comparative effects of non-negotiated pre-modified input, negotiation of input without output, and negotiation of input plus pushed output on EFL learners’ comprehension and production. Before starting the study, forty-three male and female adult students at intermediate level took the Preliminary English Test (PET) and 30 of the students who scored one ...

Ethiopian immigrants in South Africa are increasingly occupying informal trading space townships, rural areas and select central business districts across the country. This article documents experiences of migrants sector Africa. Theoretically, rests on concept everyday life. It draws data from interviews, focus group discussions observations carried out between October 2020 September 2021. sig...

A patent pending, energy based, method is presented for controlling a haptic interface system to ensure stable contact under a wide variety of operating conditions. System stability is analyzed in terms of the time domain definition of passivity. We define a "Passivity Observer" (PO) which measures energy flow in and out of one or more subsystems in real-time software. Active behavior is indica...

We hypothesized that reducing arterial O2 content ([Formula: see text]) by lowering the hemoglobin concentration ([Hb]) would result in a higher blood flow, as observed with a low [Formula: see text], and maintenance of O2 delivery. Seven young healthy men were studied twice, at rest and during two-legged submaximal and peak dynamic knee extensor exercise in a control condition (mean control [H...
