Functional activity of peptide ion channels in tethered bilayer lipid membranes: Review
Electrochemical Science Advances, Volume 2, Issue 6, December 2022., 2022 Abstract Ion transport across biomembranes plays a major role in living cells. This fundamental function is normally carried out by molecules with both a hydrophobic and a hydrophilic side (amphiphilic molecules), which aggregate within the membrane forming a hydrophilic pore (the ion channel) permitting the selective translocation of permeant ions ...

General and mechanistic optimal relationships for tensile strength of doubly convex tablets under diametrical compression [PDF]
, 2014 We propose a general framework for determining optimal relationships for tensile strength of doubly convex tablets under diametrical compression. This approach is based on the observation that tensile strength is directly proportional to the breaking force and inversely proportional to a non-linear function of geometric parameters and materials ...

Preformulation Studies for Generic Omeprazole Magnesium Enteric Coated Tablets
BioMed Research International, 2015 Preformulation is an important step in the rational formulation of an active pharmaceutical ingredient (API). Micromeritics properties: bulk density (BD) and tapped density (TD), compressibility index (Carr’s index), Hauser’s ratio (H), and sieve analysis were performed in order to determine the best excipients to be used in the formulation development

Detection of Dangerous Magnetic Field Ranges from Tablets by Clustering Analysis [PDF]
arXiv, 2016 The paper considers the problem of the extremely low frequency magnetic field radiation generated by the tablet computers. Accordingly, the measurement of the magnetic field radiation from a set of tablets is carried out. Furthermore, the measurement results are analyzed and clustered according to the K-Medians algorithm to obtain different magnetic ...

Logistic Growth for the Nuzi Cuneiform Tablets: Analyzing Family Networks in Ancient Mesopotamia [PDF]
arXiv, 2013 We reconstruct the year of publication of each cuneiform tablet of the Nuzi society in ancient Mesopotamia. The tablets, are on land transaction, marriage, loan, slavery contracts etc. The number of tablets seem to increase by logistic growth until saturation.

Advanced Materials, EarlyView.The sidechain doped polymer is investigated to have great potential for pressure detection due to the advantages including molecular rearrangement and charge‐density perturbance induced by micro‐mechanical deformation. This sensor displayed low‐pressure detection limit of 0.7 Pa as well as a rapid response time of 18.8 ms, enabling multi‐mode motion ...
