On Variation Mechanisms in Recurrent Nova IM Normae

open access: yesGalaxies, 2022
Light curves by Woudt and Warner (WW) of recurrent nova IM Nor show eclipse-like dips that they saw as too wide for eclipses alone, and interpreted as mainly a reflection effect due to irradiation of the companion (mass donor) star with some amplitude ...

The Effect of Angle and Shooting Position on the Accuracy of Close-Shooting in Team-Handball [PDF]

open access: yesمجلة الرافدين للعلوم الرياضية, 2006
: The Research aims at knowing the following: - Knowing the accuracy of close-shooting from various area (angle) and different position. - Knowing which position or area is more accurate than other, when close-shooting in team-handball is used.

Bearing Capacity of Closed and Open Ended Pipe Piles in Clayey Soil [PDF]

open access: yesEngineering and Technology Journal, 2016
This paper investigates the impact of close and open ended condition on the capacity of pipe piles installed in medium clayey soil using pressed or jacked and hammered techniques and tested under the effect of vertical static compression load.

Validation of a New Contactless and Continuous Respiratory Rate Monitoring Device Based on Ultra-Wideband Radar Technology

open access: yesSensors, 2021
Respiratory rate (RR) is typically the first vital sign to change when a patient decompensates. Despite this, RR is often monitored infrequently and inaccurately.

USING A SWEATING RESIDUUM/SOCKET INTERFACE SIMULATOR FOR THE EVALUATION OF SWEAT MANAGEMENT LINERS IN LOWER LIMB PROSTHETICS

open access: yesCanadian Prosthetics & Orthotics Journal, 2021
BACKGROUND: Lab-based simulators can help to reduce variability in prosthetics research. However, they have not yet been used to investigate the effects of sweating at the residuum-liner interface.

Assessment of reservoir response to flood conditions to optimize hydropower operations – Isimba HPP Uganda [PDF]

open access: yesE3S Web of Conferences, 2022
Lake Victoria is the largest tropical lake in the world and the source of river Nile, the longest river in the world. Due to prolonged precipitation above the average over the past two years, the lake water levels have increased surpassing the highest ...

Differential sensing with arrays of de novo designed peptide assemblies

open access: yesNature Communications, 2023
Differential sensing aims to mimic senses such as taste and smell through the use of synthetic receptors. Here, the authors show that arrays of de novo designed peptide assemblies can be used as sensor components to distinguish various analytes and ...

Experimental studies of electron affinity and work function from titanium on oxidised diamond (100) surfaces

open access: yesFunctional Diamond, 2022
Sub-monolayers of titanium were deposited onto oxidised (100) single-crystal diamond surfaces and annealed in vacuo at temperatures up to 1000 °C to find a temperature-stable termination procedure that produces a surface with Negative Electron Affinity ...

Resonance production in central pp collisions at the CERN Omega Spectrometer [PDF]

open access: yes, 2000
A study of resonance production in central pp collisions is presented as a function of several kinematical variables. In particular the difference in the transverse momentum (dPT) of the exchanged particles shows that undisputed qqbar mesons are ...

Exact Description of Rotational Waves in an Elastic Solid [PDF]

open access: yes, 2010
Conventional descriptions of transverse waves in an elastic solid are limited by an assumption of infinitesimally small gradients of rotation. By assuming a linear response to variations in orientation, we derive an exact description of a restricted ...
