Use of Carbonized Seed Hulls as Alternative to Bleaching Clay During Miscella Bleaching of Oils
Carbonized Seed Hulls Bleaching Clay During Miscella
2016/6/2
Soybean oil (SBO) was miscella bleached in hexane using carbonized hulls of Jojoba (Jo), Jatrova (Ja), Peanuts (PN) and Pistachios (P) as alternatives to bleaching clays. Evaluation of bleached crude ...
A Versatile Apparatus for the Bench Scale Bleaching and Deodorisation of Vegetable Oils
hexanal alkyl hydroperoxides heterolytic cleavage rapeseed oil bleaching
2015/12/30
A versatile isothermal glass apparatus provided with sintered glass on the bottom was designed for the bench scale adsorptive bleaching and deodorisation of vegetable oils. The stream of argon bubbles...
Coral Bleaching Independent of Photosynthetic Activity
Photosynthetic Activity Coral Bleaching
2015/12/11
The global decline of reef-building corals is due in part to
the loss of algal symbionts, or ‘‘bleaching,’’ during the
increasingly frequent periods of high seawater temperatures
[1, 2]. During ble...
The role of transcriptome resilience in resistance of corals to bleaching
heat stress coral bleaching transcriptomics resilience gene expression
2015/12/11
Wild populations increasingly experience extreme conditions as climate change
amplifies environmental variability. How individuals respond to environmental extremes
determines the impact of climat...
HANDS-ON OCEANOGRAPHY | A Classroom Activity Using Satellite Sea Surface Temperatures to Predict Coral Bleaching
HANDS-ON OCEANOGRAPHY Satellite Sea Surface Temperatures Predict Coral Bleaching
2015/7/3
Familiarize students with sea surface temperature (SST) and the use of satellites to remotely sense SST.Familiarize students with the effect of SST on coral health.
Photochemical bleaching of fluorescent dissolved organic matter in the subtropical North Pacific Ocean
marine humic-like fluorescent dissolved organic matter photobleaching solar irradiation size distribution hydrophobic/ hydrophilic properties Abbreviations: DIC dissolved in
2017/4/10
We examined the molecular weight distribution of the fluorescence intensity of FDOMM and dissolved organic carbon
(DOC) concentrations in the subtropical western North Pacific, in order to characteri...
Assessing the drivers of spatial variation in thermal forcing across a nearshore reef system and implications for coral bleaching
Assessing the drivers spatial variation thermal forcing across a nearshore reef system implications coral bleaching
2014/7/10
We examined the seasonal and spatial variability in the temperatures of nearshore reef waters over 19 months across Coral Bay at Ningaloo Reef, Western Australia. Local deviations in the mean daily te...
Electron-Irradiation and Photo-Excitation Darkening and Bleaching of Yb Doped Silica Fibers: Comparison
Ytterbium Doped Silica Fibers Photodarkening Electron Irradiation
2013/1/30
We report a comparative experimental study of the attenuation spectra transformations for a series of Yb doped alumino-germano silicate fibers with different contents of Yb3+ dopants, which arise as t...
Responses to iron limitation in two colonies of Stylophora pistillata exposed to high temperature: Implications for coral bleaching
Stylophora pistillata Responses coral bleaching
2014/4/8
Exposing the coral Stylophora pistillata to seawater depleted in available iron by complexation with the strong
chelator desferrioxamine B reduces the photosynthetic efficiency and alters the pigment...
Temperature-induced stress leads to bleaching in larger benthic foraminifera hosting endosymbiotic diatoms
Temperature-induced stress bleaching larger benthic foraminifera hosting endosymbiotic diatoms
2014/4/4
Physiological mechanisms of bleaching were studied on larger benthic foraminifera (LBF) hosting endosymbiotic diatoms. Amphistegina radiata, Heterostegina depressa, and Calcarina hispida were exposed ...
ECF Bleaching with Molybdenum Activated Acid Peroxide and its Impact on Eucalyptus Pulp Properties and Effluent Quality
Molybdenum Bleaching Eucalyptus Kraft Qulp Effluent Pulp Quality
2013/3/8
Acid hydrogen peroxide catalyzed with molybdenum (PMo stage) is effective to decrease pulp kappa number and potentially minimize chlorine dioxide demand in subsequent ECF bleaching. This study aimed a...
