Chemistry and source of the dissolved inorganic carbon of sediments porewater in Huixian karst wetland

Shuiwen dizhi gongcheng dizhi
The ecological environment of karst wetland is highly fragile, and both natural processes and human activities have led to the gradual deterioration of wetland water quality. However, the influence on the evolution of carbon remains unclear.

Illinois River Volunteer Monitoring [PDF]

, 2009
Understanding how water quality conditions change along a land use gradient and over time is important for sustainable watershed management. Therefore, a volunteer monitoring program was created to measure water chemistry at 37 established sites within ...

Cell wall target fragment discovery using a low‐cost, minimal fragment library

FEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Water destruction by X-rays in young stellar objects

, 2006
We study the H2O chemistry in star-forming environments under the influence of a central X-ray source and a central far ultraviolet (FUV) radiation field. The gas-phase water chemistry is modeled as a function of time, hydrogen density and X-ray flux. To

Behaviours of natural organic matter in membrane filtration for surface water treatment : a review [PDF]

, 2006
Membrane application in surface water treatment provides many advantages over conventional treatment. However, this effort is hampered by the fouling issue, which restricts its widespread application due to increases in hydraulic resistances, operational

Inhibiting stearoyl‐CoA desaturase suppresses bone metastatic prostate cancer by modulating cellular stress, mTOR signaling, and DNA damage response

FEBS Letters, EarlyView.
Bone metastasis in prostate cancer (PCa) patients is a clinical hurdle due to the poor understanding of the supportive bone microenvironment. Here, we identify stearoyl‐CoA desaturase (SCD) as a tumor‐promoting enzyme and potential therapeutic target in bone metastatic PCa.

Structure and stability of graphene nanoribbons in oxygen, carbon dioxide, water, and ammonia [PDF]

, 2010
We determine, by means of density functional theory, the stability and the structure of graphene nanoribbon (GNR) edges in presence of molecules such as oxygen, water, ammonia, and carbon dioxide.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Geochemical assessment of Simav geothermal field, Turkey

Revista Mexicana de Ciencias Geológicas, 2018
In this study, geochemical methods are used to reliably analyze and understand the Simav geothermal field whose thermal water is rich in terms of Na-HCO3-SO4 and is affected by groundwater which is low in Cl.
