Project design of an open pit colliery in Terkidag, Turkey [PDF]

Acta Montanistica Slovaca, 2010
In this manuscript, first of all, the status of Turkey in terms of energy production and consumption is given and the need to relyon domestic sources, namely lignite deposits, is emphasized rather than importing fuels from abroad.

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Planejamento agregado da produção ótimo com limite mínimo de estoque influenciado pelas incertezas de demanda Optimal aggregate production planning with minimum inventory limit affected by demand uncertainties

Gestão & Produção, 1995
O artigo trata da determinação de uma política ótima de decisão para um problema de planejamento da produção com restrições de estoque e produção. O horizonte de planejamento é finito, aproximadamente de 1 a 2 anos, com período de discretização mensal ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Compartilhamento da informação como elemento de coordenação da produção em cadeia de suprimento Information sharing as an element of production coordination in supply chains

Gestão & Produção, 2005
Este artigo estuda o planejamento da produção de uma cadeia de suprimento sob três cenários distintos de gestão e compartilhamento da informação, por meio de um modelo de otimização. No primeiro cenário são utilizadas somente as informações locais.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

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

FEBS 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 ...
