A mixed integer optimization strategy for oil and gas production planning [PDF]

open access: yes, 2008
Oil and gas production is the cornerstone of the modern petrochemical industry, and its upstream as well as downstream processing provides many challenges to the process modeling, optimization and control areas.

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Technoeconomic evaluation of flared natural gas reduction and energy recovery using gas-to-wire scheme [PDF]

open access: yes, 2013
Most mature oil reservoirs or fields tend to perform below expectations, owing to high level of associated gas production. This creates a sub-optimal performance of the oil production surface facilities; increasing oil production specific operating ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Impact of Natural Gas Price Decontrol on Gas Supply, Demand and Prices [PDF]

open access: yes, 1982
Major analysis completed recently by the gas transmission and distribution industry concludes that available supplies of gas energy will fall into the range of 23-31 trillion cubic feet (Tcf) by the year 2000, as conventional gas production is ...

Hippo pathway at the crossroads of stemness and therapeutic resistance in breast cancer

open access: yesMolecular Oncology, EarlyView.
Dysregulation of the Hippo pathway drives nuclear accumulation of YAP/TAZ, activating stemness‐related transcriptional programs that sustain breast cancer stemness and fuel therapeutic resistance across subtypes, underscoring Hippo signaling as a targetable vulnerability. Figure created and edited with BioRender.com.
