Introduction: Calcium critical limit in pistachio plants is about 1.3 percent of plant dried material; magnesium critical limit in pistachio leaves is about 0.6 percent of plant dried material. To measure calcium and magnesium there are several methods in which three methods of titration and atomic absorption that are more common and used to libraries more in addition to ICP modern method are u...

It is well known [4, p. 265; 3] that the space 7,i[0, l] is not isomorphic with a conjugate space. At the other extreme, it is also well known that h is isometric with the conjugate space of Co. Each of these is an example of a space of all real-valued integrable functions over a measure space (T, p), a major difference between them being that the measure space underlying 7_i[0, l] has no atoms...

We introduce a topology T on the space U of uniformly discrete subsets of the Euclidean space. Assume that S in U admits a unique autocorrelation measure. The diffraction measure of S is purely atomic if and only if S is almost periodic in (U,T ). This result relates idealized quasicrystals to almost periodicity. In the context of ergodic point processes, the autocorrelation measure is known to...

The interest in mechanical properties of two-dimensional materials has emerged in light of new device concepts taking advantage of flexing, adhesion and friction. Here we demonstrate an effective method to measure adhesion of graphene atop highly ordered pyrolytic graphite, utilizing atomic-scale 'blisters' created in the top layer by neon atom intercalates. Detailed analysis of scanning tunnel...

The apparatus used in the experiment which is the subject of this communication is related to that named after Puccianti.' It consists essentially of identical tubes about 85 cm. long with optically plane parallel ends placed in the arms of an interferometer and filled to the same pressure with hydrogen. A powerful discharge was passed through one of the tubes while "white-light" fringes from a...

Let L be a linear space of real bounded random variables on the probability space (Ω,A, P0). A finitely additive probability P on A such that P ∼ P0 and EP (X) = 0 for each X ∈ L is called EMFA (equivalent martingale finitely additive probability). In this note, EMFA’s are investigated in case P0 is atomic. Existence of EMFA’s is characterized and various examples are given. Given y ∈ R and a b...

The time is the physical quantity that mankind could measure with the best accuracy, thanks to the properties of the atomic physics, as the present definition of time is based on atomic energy transitions. This short review gives some basic information on the heart of the measurement of time in the contemporary world, i.e. the atomic clocks, and some trends related.

The situation in which every quasi-measure extension of a given measure is σ-additive is characterized in the case of an atomic or two-valued measure. Subject Classifications: 28A12

Center foliations of partially hyperbolic diffeomorphisms may exhibit pathological behavior from a measure-theoretical viewpoint: quite often, the disintegration of the ambient volume measure along the center leaves consists of atomic measures. We add to this theory by constructing stable examples for which the disintegration is singular without being atomic. In the context of diffeomorphisms w...

We develop a temperature measurement of an atomic cloud based on the temporal correlations of fluorescence photons evanescently coupled into an optical nanofiber. We measure the temporal width of the intensity-intensity correlation function due to atomic transit time and use it to determine the most probable atomic velocity, hence the temperature. This technique agrees well with standard time-o...
