The Removal of Fluoride Ions from Wastewater Produced During Uranium Recovery in Three Groups of Uranium Conversion Factory Scraps Using Chemical Precipitation Method [PDF]

open access: yesمجله علوم و فنون هسته‌ای, 2017
In the present research work, high concentration amounts of fluoride ions in nuclear waste produced during uranium recovery from the three groups of uranium conversion factory scraps (C36, C37, 56P) were removed by the chemical precipitation method.

Stability of PMR-polyimide monomer solutions [PDF]

open access: yes
The stability of alcohol solutions of norborneyl capped PMR-polyimide resins was monitored during storage at ambient and subambient temperatures. Chemical changes during storage were determined spectroscopically using nuclear magnetic resonance.

Interim report on the hydrologic features of the Green Swamp area in Central Florida [PDF]

open access: yes, 1961
The Green Swamp area in central Florida is another area where man is developing agricultural land from marginal land. Though the area is by no means as extensive as that of the Everglades, the present efforts for its development are similar to the ...

A reaction-diffusion model for the hydration/setting of cement

open access: yes, 1995
We propose a heterogeneous reaction-diffusion model for the hydration and setting of cement. The model is based on diffusional ion transport and on cement specific chemical dissolution/precipitation reactions under spatial heterogeneous solid/liquid ...

A thermochemical approach for calcium phosphate precipitation modeling in a pellet reactor [PDF]

open access: yes, 2003
A common pathway for P-recovery from wastewater is phosphate precipitation as calcium phosphates. In this paper, a thermodynamic model for phosphate precipitation is proposed based on various models of activity coefficients taking into account various ...

MiR‐513a promotes human erythroid differentiation by modulating c‐Jun

open access: yesFEBS Open Bio, EarlyView.
During early human erythropoiesis, miR‐513a promoted erythroid differentiation in primary human CD34+ hematopoietic stem‐progenitor cells and human TF‐1 erythroleukemic cells by indirectly decreasing c‐Jun and phospho‐c‐Jun expression, which are associated with increased GATA1 expression.

Ball-milling of Talc for Disposing Ni2+ Contaminated Sewage

open access: yesKuangchan zonghe liyong
In order to achieve the efficient removal of heavy metal nickel ions in water and simultaneously recover nickel secondary resources, the natural talc mineral was modified by simple ball-milling process and directly applied for the purification of nickel ...

The spatial variation of Asian dust and marine aerosol contributions to glaciochemical signals in central Asia [PDF]

open access: yes, 1992
Short-term (6 months to 17 years) glaciochemical records have been collected from several glacier basins in the mountains of central Asia. The spatial distribution of snow chemistry in central Asia is controlled by the influx of dust from the large ...

Large‐scale bidirectional arrayed genetic screens identify OXR1 and EMC4 as modifiers of αSynuclein aggregation

open access: yesFEBS Open Bio, EarlyView.
Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.
