CONSTRUCTION ENGINEERING AND CONSTRUCTION MATERIALS

open access: yesEPRA International Journal of Multidisciplinary Research (IJMR), 2019
Construction Engineering is very important part of Civil Engineering. We can’t think about a good and stable structure without good quality of construction. And the construction materials is also play an important role for any construction work. Construction engineering is a professional discipline that deals with the designing, planning, construction ...

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

open access: yesFEBS 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.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Use of Strain-Hardening Cement-Based Composites (SHCC) for Retrofitting

open access: yesMATEC Web of Conferences, 2018
Strain-hardening cement-based composites (SHCC, or Engineered Cementitious Composites, ECC) were developed in the early 1990th and have been since then an object of numerous investigations which number increases every year.

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

open access: yesFEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Some durability aspects of hybrid alkaline cements

open access: yesMATEC Web of Conferences, 2014
Blended cements that contain a high content of fly ash and a low content of Portland cement typically suffer from low early strength development and long setting times. Recently, one method of overcoming these problems has been to use an alkali activator
