Serine-based β-lactamases of Class A, C and D all rely on a key water molecule to hydrolyze and inactivate β-lactam antibiotics. This process involves two conserved catalytic steps. In the first acylation step, the β-lactam antibiotic forms an acyl-en
This is why, when introducing chemical bonding, I refrain from lecture. Instead, the first day the students use wooden balls and sticks to build molecular models from different formulas (my Latin teacher is wincing;formulaeis the true plural). Through this experience, students learn that subscri...

(Evolution. 11 212–224)As early as 1957, Savile, an engineer, was able to examine the wings of birds to determine how the aerodynamics of the wings work. In particular, how does air flow over the wing? For any plane, air flows over the edges, causing turbulence that prevents lift. B...

11. What is the benefit of using My Shadow Poem Class 5 Notes? The benefit of using My Shadow Poem Class 5 Notes is that they break down the poem into easily understandable sections, helping students to thoroughly understand and enjoy the poem while preparing for exams....
A- My valentines day was sick. Helen and i woke up and went for a burrito, followed by a trip to oxfam where we found Edward Sissorhands. Then we went back home to watch it in bed. haha. we ended the night by going to a Male Bonding and Graffiti Island show at the lexington. ...
The chemical structure of the nanoparticle is critical to ensure its miscibility in the PLLA/PDLA matrix. The –OH and C=O groups in lignin enhance the mixing capability with PLLA/PDLA blends through hydrogen bonding [93]. Despite MWCNT in PLLA/PDLA blends being able to yield stereocomplex ...
