About the continuous spectrum of vibrations of beam construction elements under high-frequency effects [PDF]

open access: yesИнженерно-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

open access: yesMathematics, 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

open access: yeseLife, 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

open access: yesA 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

Moda i semiotika roda

open access: yesEtnoantropološki Problemi, 2016
Odevanjem tela, oduvek je bilo moguće slati određene poruke okolini. Uostalom, o komunikacionoj sposobnosti odeće pisali su mnogi teoretičari. Simbolički potencijal odevnih formi vezivan je i za njihove drevne oblike. Savremene studije mode tumače odevni

From line to dots: an improved computerised rod and frame system for testing subjective visual vertical and horizontal

open access: yes, 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
