From line to dots: an improved computerised rod and frame system for testing subjective visual vertical and horizontal [PDF]
, 2010 Background Perception of subjective visual vertical (SVV) and horizontal (SVH) has traditionally been measured by rotating a mechanical rod either with or without a frame present. The computerised rod and frame (CRAF) system has previously only been used

About the continuous spectrum of vibrations of beam construction elements under high-frequency effects [PDF]
Инженерно-строительный журнал, 2012 In this paper the high-frequency vibrations of beam structural elements on the example of cantilever rod are analyzed. The purpose of this article is to show the existence of the boundary frequency, above which the structure behaves as a system with a ...

The Problem of Boundary Control of the Thermal Process in a Rod
Mathematics, 2023 This paper considers a rod with an insulated side surface, at the edges of which there is heat exchange with the external environment. It is assumed that the thermal process in the rod is controlled by the effect of the ambient temperature on the thermal

A Cambrian origin for vertebrate rods
eLife, 2015 Vertebrates acquired dim-light vision when an ancestral cone evolved into the rod photoreceptor at an unknown stage preceding the last common ancestor of extant jawed vertebrates (∼420 million years ago Ma).

Feministički pristup povijesti umjetnosti
A Priori, 2023 U ovom radu su iznešena stanovišta progresivnih feminističkih pionirki i njihovi kritički stavovi koji će osvijetliti put današnjoj ženi. Otkrivajući sudbinu žene kroz vrijeme muškog sistema neophodno je dati uvid u ženske vrijednosti koje su protkane u

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions
FEBS Letters, EarlyView.The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.
