The aim of this systematic review and meta‐analysis was to critically assess the published
literature related to community‐acquired viral co‐infections and COVID‐19 and to evaluate …

The substitution of a logarithmic variable in the Gaussian function yields a logarithmic probability
law (the normal phi curve) which has all the geometrical properties of the conventional …

Distinction is made between continuous and discontinuous variables in frequency distributions.
Histograms, frequency curves, and cumulative curves are discussed in relation to each …

Microcodium has been previously described as a mainly Cenozoic calcification pattern ascribed
to various organisms. A review of the available literature and our data reveal two peaks …

Earlier work on the abrasion of rock fragments in tumbling barrels is reviewed, and the main
principles are summarized. Most earlier work concerned one or another aspect of abrasion …

Glucosinolates (GLSs) are found in Brassica vegetables. Examples of these sources include
cabbage, Brussels sprouts, broccoli, cauliflower and various root vegetables (eg. radish …

A symbol for the negative logarithm of grain diameters to the base 2 is introduced as a device
for statistical computation. The advantages of the symbol are that it simplifies geometric …

Present methods of mechanical analysis are confined to rocks that can be separated into their
component grains. This restriction is partly removed by a new method in which correction …

Pebbles from glacial till, from an outwash terrace, and from a beach show characteristic
preferred orientations. Methods used in collecting and measuring the pebbles are described, …

The relation between permeability and the size parameters of unconsolidatedsand is
approached by considering sands as logarithmic frequency distributionshaving the basic …
