Relationships between trace elements and atherosclerosis
Science of The Total Environment, 1985The possible relationship between trace element (Al, As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Mo, Ni, Pb, Sb, Se, Zn) concentrations in various human tissues (heart, liver, kidney, aorta, rib and head hair) and cardiovascular diseases was studied on the basis of indications in the literature that trace elements may be directly or indirectly involved in ...

On the pressure-volume relationship in circulatory elements
Medical & Biological Engineering & Computing, 1982A generalisation of the equation used bySalazar (1964) to fit the pressure-volume relationship of normal human lungs between FRC and TLC is found to fit the pressure-volume relationship of a variety of circulatory elements. The equation contains only two fundamental physiologic parameters: one a compliance constant k and the other a maximum element ...

Relationships between elements of the Stokes matrix
Applied Optics, 1981Although there are sixteen elements of the Stokes matrix, they are constructed from basically four amplitudes and three phase differences. This of course implies that there exist nine independent relationships connecting the elements. These relationships are equalities for scattering by a single particle in a fixed orientation and in a fixed direction.

Elements of Pathological Love Relationships
Psychological Reports, 1983The present discussion specifies a number of elements which seem to be involved in functional and pathological relationships. Since the stability of such relationships may be attributable to the manner in which “love” is transacted and interchanged, it seems advisable for the clinician to utilize a more precise set of criteria against which both ...

Seminal trace elements and their relationship with sperm parameters
Andrologia, 2022Male reproductive problems may derive from many reasons including the environmental toxicants which may either intaken by occupational exposure, nutrition or bad air quality. The increased exposure to these substances due to rapid industrial development and technology has raised the questions: Is there a relationship between sperm parameters and these ...

The Elements of Lawlike Relationships
Journal of the Royal Statistical Society. Series A (General), 1968SUMMARY Much of what we know in science is as yet confused by uncertainty. But implicit in our observed phenomena are many lawlike relationships saying that if this occurs, so does that. The systematic uncovering of such relationships and their subsequent applications to practical problems are how science and how technology progress.

Major Element Relationships in Tektites
Nature, 1960THE chemical composition of tektites is a major factor to be considered when investigating theories of tektite origin. Many investigators have remarked on the similarity of the composition of tektites to certain types of sedimentary rocks, and this fact has been held to be indicative of a terrestrial origin.

Unpouching Peracarida relationships with ultraconserved elements
Molecular Phylogenetics and EvolutionAbstract Peracarida is a large group containing twelve orders of brooding crustaceans, including the large orders Amphipoda, Isopoda, Tanaidacea and Cumacea, and a series of smaller orders, some restricted to isolated habitats. The relationships of Peracarida have been disputed and no attempt has been made to use extensive taxon ...

Soil-Plant Relationships of Radioactive Elements
Health Physics, 1965Abstract The plant concentration of various radioactive elements, after they have been added to soils in water-soluble forms, may be several orders of magnitude higher or lower than the concentration in the soil. Those that are most readily absorbed are soluble in the soil or are isotopic with elements that have metabolic functions in the plant. Those

Some elements and their relationships in Ascaris suum
International Journal for Parasitology, 1976Abstract Analytical determinations for several elements in the tissues of Ascaris suum have been made at the University of London Reactor Centre by the method of activation analysis. Results are given in this paper for the concentrations of the elements iron, cobalt, zinc, caesium, silver, indium, cerium, scandium, selenium, antimony, rubidium ...
