Suppression of star formation in early-type galaxies by feedback from supermassive black holes
(2006-08-24)Detailed high-resolution observations of the innermost regions of nearby galaxies have revealed the presence of supermassive black holes. These black holes may interact with their host galaxies by means of 'feedback' in ... -
Suppression of the postoperative neutrophil leucocytosis following neoadjuvant chemoradiotherapy for rectal cancer and implications for surgical morbidity
(2010)Objective: The extent to which neoadjuvant chemoradiotherapy for rectal cancer influences postoperative morbidity is controversial. This study investigated whether this treatment suppresses the normal perioperative ... -
Suppression of the soybean cyst nematode, Heterodera glycines, by short-term field cultivation and soil incorporation of mung bean.
(2020-08-31)Our previous study using pots reported that short-term growth of mung bean (Vigna radiata) may be useful to decrease the density of the soybean cyst nematode (SCN), Heterodera glycines, in soil. The objective of this study ... -
Suppression of the stellar enhancement factor and the reaction Rb-85(p, n)Sr-85
(2009-09)It is shown that a Coulomb suppression of the stellar enhancement factor occurs in many endothermic reactions at and far from stability. Contrary to common assumptions, reaction measurements for astrophysics with minimal ... -
Suppression of virus induced local lesions in plasmolysed leaf tissue
(1978-05-01)It has been demonstrated previously that protoplasts derived from leaves which normally respond in vivo to virus inoculation, with the formation of necrotic local lesions show no such response when inoculated in vitro [1]. ... -
Supraglacial ponds regulate runoff from Himalayan debris-covered glaciers.
(2017-12-16)Meltwater and runoff from 1 glaciers in High Mountain Asia is a vital freshwater resource for one fifth of the Earth’s population. Between 13% and 36% of the region’s glacierized areas exhibit surface debris cover and ... -
Surface Defect Classification for Hot-Rolled Steel Strips by Selectively Dominant Local Binary Patterns
(2019-02-11)Developments in defect descriptors and computer vision-based algorithms for automatic optical inspection (AOI) allows for further development in image-based measurements. Defect classification is a vital part of an ... -
Surface images of the short period contact binary AE Phe
(2004)We present high resolution Doppler images of the short period (P = 0.362 d) contact binary AE Phe. Using least squares deconvolution, we make use of the information content of the several thousand lines in each echelle ... -
Surface interactions and viability of coronaviruses
(2021-01-06)The recently emerged coronavirus pandemic (COVID-19) has become a worldwide threat affecting millions of people, causing respiratory system related problems that can end up with extremely serious consequences. As the ... -
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 ...
