The lipophilic dicarboxylic acid-dicarboxamide macrocycle 1 is an efficient carrier for calcium and potassium transport through a liquid membrane. The process involves competitive Ca2'/K' symport coupled to proton antiport in a pH gradient. It presents a very pronounced phenomenon of pH regulation of transport selectivity from preferential K+ transport to preferential Ca2' transport as the pH i...

A simple theory of the diamagnetic anisotropy of noncyclic planar groups of atoms with resonance structures (mobile electrons)leads to the value --5.36 x 10(-6) cm-g-sec electromagnetic units for the molar diamagnetic anisotropy of the peptide group.

We classify two types of finite groups with certain normality conditions, namely SSN groups and groups with all noncyclic subgroups normal. These conditions are key ingredients in the study of the multiplicative Jordan decomposition problem for group rings.

C hronic pelvic pain is defined in a variety of ways. a useful clinical definition of chronic pelvic pain is noncyclic pain that lasts six months or more; is localized to the pelvis, the anterior abdominal wall at or below the umbilicus, or the buttocks; and is of sufficient severity to cause functional disability or require medical care. other definitions do not require that the pain be noncyc...

Abstract The purpose of this short note is to present a correction the proof main result given in paper “ Equivalence existence best proximity points and pairs for cyclic noncyclic nonexpansive mappings ,” Demonstr. Math. 53 (2020), 38–43.

Noncyclic populations of microtine rodents may be limited within a relatively constant range of densities by generalist predators with a prey base sufficiently diverse to sustain them when rodents are scarce (generalist predator hypothesis). Collared lemmings (Dicrostonyx kilangmiutak) at Pearce Point, Northwest Territories, Canada, are noncyclic and limited to fairly constant low densities in ...
