A Study of Tribological Properties of Water-Based Ceria Nanofluids
(2013-03-01)This paper presents an investigation on the potential tribological properties of the water-based cerium dioxide nanofluids. The nanofluids with different nanoparticle concentrations were prepared in a materials laboratory. ... -
A study of two post-common envelope binary systems
(2005)We present intermediate-resolution, phase-resolved spectra of the close-binary systems EC 11575−1845 and V664 Cas, the central star of the planetary nebula HFG 1. Both systems have a very rich emission-line spectrum ... -
Study on behaviour and mechanism of Cu2+ ion release from Cu bearing antibacterial stainless steel
(2015-08-30)Cu bearing stainless steels (Cu SS) possess antibacterial ability due to the release of Cu<sup>2+</sup> ions. However, the release mechanism of Cu<sup>2+</sup> ions from the steel is still unclear. Therefore, the passive ... -
Study on characteristics of particulate emission of diesel aftertreatment with reciprocating flow
(2021-04-01)In this article, in order to optimize diesel aftertreatment system with periodically reciprocating flow (PRF), an experimental study is conducted to investigate its characteristics such as pollution emissions, regeneration ... -
A Study on the Ability of Different Non-Intrusive Sensors for Diagnosing Outdoor Insulator Defects
(2023-07-14)Insulators’ failures caused by any type of defect may result in serious technical and economic losses. In particular, contamination flashovers due to excessive pollution and humidity are one of the main problems encountered ... -
A study on the influence of Ni-Ti M-Wire in the flexural fatigue life of endodontic rotary files by using Finite Element Analysis
(2014-07-01)The aim of this paper is to analyze the cyclic performance of two different Ni-Ti endodontic rotary files made from different alloys under bending using Finite Element Analysis (FEA). When experimentation is not available, ... -
Study on thermal-hydraulic characteristics of novel channels for printed circuit heat exchanger using supercritical CO2
(2023-11-01)Two new types of printed circuit heat exchanger (PCHE) channels are proposed based on the typical airfoil fin PCHE channel proposed in literatures (standard channel) to further improve the thermal-hydraulic performances ... -
Study the role of silicon in strawberries and its possible role in control of strawberry powdery mildew
(2011)Silicon has been shown to control a number of diseases. The physical effect of silicon on strawberry plants is unknown. Omex SW7 is a silicon based wetter, which is used in the application of potassium bicarbonate for the ... -
A Study to Examine Patient Adherence to Wearing 24-Hour Forearm Thermoplastic Splints after Tendon Repairs
(2008)Adherence is believed to be essential in ensuring a successful clinical outcome. There is a paucity of research available investigating adherence and the effect of nonadherence in hand therapy. This study was conducted to ... -
A Study to understand lead-lag performance of Subject vs Rehabilitation System
(ACM Press, 2012-03-08)Robotic assistance in stroke rehabilitation is rapidly advancing based on the recent developments in robotics, haptic interfaces and virtual reality. GENTLE/S is a rehabilitation system that utilizes haptic and virtual ... -
Studying tacit food and eating practices using visual research and diary methods – Methodological symposium : The Diary/interview method: Researching Nutrition Information Seeking Behaviour
(2017-06-27)Research that aims to investigate tacit and mundane practices such as those relating to food and eating is increasingly making use of ‘non-traditional’ social scientific research methods. Visual research and diary methods ... -
Studying Taklamakan Aerosol properties with Lidar (STAPL)
(SPIE, 2013)By now, the global impacts of atmospheric dust have been well-established. Nevertheless, relevant properties such as size distribution, depolarization ratio, and even single-scattering albedo have been shown to vary ... -
Studying the late evolution of a radio-loud AGN in a galaxy group with LOFAR
(2018-03-11)Feedback by radio-loud active galactic nuclei (AGNs) in galaxy groups is not fully understood. Open questions include the duty cycle of theAGN, the spatial extent of the radio lobes, the effect they have on the intragroup ... -
Studying the spatially resolved Schmidt-Kennicutt law in interacting galaxies : The case of Arp 158
(2011-09)Context. Recent studies have shown that star formation in mergers does not seem to follow the same Schmidt-Kennicutt relation as in spiral disks, presenting a higher star formation rate (SFR) for a given gas column density. ... -
Studying the YMC population of M83: how long clusters remain embedded, their interaction with the ISM and implications for GC formation theories
(2015-05-01)The study of young massive clusters can provide key information for the formation of globular clusters, as they are often considered analogues. A currently unanswered question in this field is how long these massive clusters ... -
