Surface Modification of Silica Particles with Adhesive Functional Groups or Their Coating with Chitosan to Improve the Retention of Toothpastes in the Mouth
(2023-01-31)Silica is widely used in the oral care formulations to act as an abrasive and to give the products its distinct physical properties. In this study, silica particles were synthesized using a co-condensation of tetraethyl ... -
The surface modifications of multi-walled carbon nanotubes for multi-walled carbon nanotube/poly (ether ether ketone) composites
(2015-10-30)The effects of surface modifications of multi-walled carbon nanotubes (MWCNTs) on the morphology, dynamic mechanical and tribological properties of multi-walled carbon nanotube/poly(ether ether ketone) (MWCNT/PEEK) composites ... -
Surface Morphology Evolution Mechanisms of InGaN/GaN Multiple Quantum Wells with Mixture N2/H2-Grown GaN Barrier
(2017-05-16)Surface morphology evolution mechanisms of InGaN/GaN multiple quantum wells (MQWs) during GaN barrier growth with different hydrogen (H2) percentages have been systematically studied. Ga surface-diffusion rate, stress ... -
Surface roughness during depositional growth and sublimation of ice crystals
(2018-09-27)Ice surface properties can modify the scattering properties of atmospheric ice crystals and therefore affect the radiative properties of mixed-phase and cirrus clouds. The Ice Roughness Investigation System (IRIS) is a new ... -

Surfing the photon noise : New techniques to find low-mass planets around M dwarfs
(2013-02)The current precision radial velocities techniques to detect low mass planets in M dwarf are quickly reviewed. This includes high resolution spectroscopic observations made both in the optical and in the near infrared. We ... -
Surfing the Turbulence: Fluctuations in Self-Perceptions of Expertise in the Long Term Developmental Journeys of Expert-Like Male Sports Coaches
(2017-07-20)The aim of this study is to investigate how self-perceptions of expertise among sports coaches may develop, regress, and redevelop over time within the context of coaching, in light of recent reconceptualisations of ... -
The surgical treatment of rheumatoid arthritis : a new era?
(2014-10)There has been an in increase in the availability of effective biological agents for the treatment of rheumatoid arthritis as well as a shift towards early diagnosis and management of the inflammatory process. This article ... -
A surprising consistency between the far-infrared galaxy luminosity functions of the field and Coma
(2014-08-01)We present new deep images of the Coma Cluster from the ESA Herschel Space Observatory at wavelengths of 70, 100 and 160 μm, covering an area of 1.75 × 1.0 square degrees encompassing the core and south-west infall region. ... -
Surprisingly different starspot distributions on the near equal-mass equal-rotation-rate stars in the M dwarf binary GJ 65 AB
(2017-10-11)We aim to understand how stellar parameters such as mass and rotation impact the distribution of starspots on the stellar surface. To this purpose, we have used Doppler imaging to reconstruct the surface brightness ... -
Surrogacy Mothers Entitled To Leave
(2013-10-04)Report of the preliminary ruling of Advocate General Kokott in the Court of Justice of the European Union on CD v ST relating to the rights of commissioning mothers in a surrogacy arrangement to take maternity leave and ... -
Surround & Squash : The Interstellar Medium around Scorpius Centaurus OB2
(2018-11-13)Context. Feedback by massive stars shapes the interstellar medium and is thought to influence subsequent star formation. The details of this process are under debate. Aims. We exploited observational constraints on stars, ... -
A survey for post-common-envelope binary stars using GALEX and SDSS photometry
(2009)We report the first results of our programme to obtain multi-epoch radial velocity measurements of stars with a strong far-ultraviolet excess to identify post-common-envelope binaries (PCEBs). The targets have been identified ... -
A Survey of Access Control Models in Wireless Sensor Networks
(2014-06-20)Wireless sensor networks (WSNs) have attracted considerable interest in the research community, because of their wide range of applications. However, due to the distributed nature of WSNs and their deployment in remote ... -
A survey of adverse drug reaction reporting by hospital pharmacists to the Committee on Safety of Medicines - the role of pharmacy departments
(1999-09)Objectives - To identify: (1) how adverse drug reaction (ADR) reporting by hospital pharmacists is managed, (2) the education of pharmacy personnel on ADR reporting, (3) pharmacy personnel with a specific role in ADR ... -
A Survey of Current YouTube Video Characteristics
(2015-06-22)Given the impact of YouTube on Internet services and social networks, a healthy quantity of research has been conducted over the past few years. The majority of studies on traffic capture and evaluation were carried out ... -
