Accordingly, 1.83-m (6-feet) social distancing is advised to reduce the spread of the disease among humans. This is based on the assumption that no air circulation exists around people. However, it is not well investigated whether the ambient wind and relative humidity (RH) will cause SARS-...
Assess the relative strengths of acids and bases according to their ionization constants Rationalize trends in acid–base strength in relation to molecular structure Carry out equilibrium calculations for weak acid–base systemsThe relative strength of an acid or base is the extent to which it ionize...
For proteins of known structure, the relative enthalpic stability with respect to wild-type, ΔΔHU, can be estimated by direct computation of the folded and unfolded state energies. We propose a model by which the change in stability upon mutation can be predicted from all-atom molecular dynam...
What effect has a directional bond on the weight to volume ratio of in an atomic arrangement? Why do you think metals usually have higher densities than other materials? Why is the term molecular mass inappropriate for NaCl? Why is conservation of mass important to know for chemistry? Why...
The pellet was suspended in 10 ml of ice-cold homogenization medium (100 mM NaCl, 20 mM Na-HEPES, 10 mM EDTA, pH = 7.4) and homogenized on ice by two 30 sec strokes using a Polytron homogenizer (Ultra-Turrax; Janke & Kunkel GmbH & Co. KG, IKA-Labortechnik, Staufen...
Response to an agonist is affected by the system, mainly by the expression level of the receptor. Mass action law dictates that the relationship between occupancy and effect must be hyperbolic. Therefore, response to agonist according to the OM is described by Eq. (1), where EMAXis the maxim...
Here, we report the molecular mechanism of Hub1 action, which is independent of Snu66. We show that Hub1 contains a second functional surface, via which it binds to the DEAD-box helicase Prp5 that is involved in the early stage of spliceosome assembly. Hub1 is required for the formation...
For instance, during evaporation of water containing inorganic salts such as NaCl, salt concentration increases, and in the bulk phase, salt crystallization typically occurs upon reaching saturation. However, in small droplets, salt concentration can overcome the solubility limit and can push the ...
