abstract- to study the effect of tree roots on increasing water infiltration in soil and also to determine and assess the coefficients of different infiltration models, some infiltration tests were performed in three tree plantation areas in badjgah, fars province with different soil textures (clay loam for pear plantation, sandy loam for grape plantation, loamy sand for pine trees). in each pl...

What should the goals of scientific inquiry be? What questions should scientists investigate, and how should our resources be distributed between different lines of investigation? Philip Kitcher has suggested that we should answer these questions by appealing to an ideal based on the consideration of hypothetical democratic deliberations under ideal circumstances. This paper examines possible a...

This special issue of Soil Science celebrates the enormous accomplishments made during the past century or more in the field of soil science, including some of the key articles published in Soil Science during its 90 years of existence. In this article, we focus on the contributions in soil physics, exemplified by the articles of Willard Gardner (1919) and John Philip (1957c), both of which are...

We study the class of functions called monodiffric of the second kind by Rufus Philip Isaacs. They are discrete analogues of holomorphic functions of one or two complex variables. Discrete analogues of the Cauchy–Riemann operator, of domains of holomorphy in one discrete variable, and of the Hartogs phenomenon in two discrete variables are investigated. Two fundamental solutions to the discrete...

The colon is a site where both local and systemic delivery of drugs can take place. Local delivery allows topical treatment of inflammatory bowel disease. However, treatment can be made effective if the drugs can be targeted directly into the colon, thereby reducing the systemic side effects. This review, mainly compares the primary approaches for CDDS (Colon Specific Drug Delivery) namely prod...

In a recent review, Gurr and colleagues have surveyed the threats from emerging and spreading fungal diseases both to crops and to wildlife (Nature (2012) 484, 186–194). While it is common that pathogenic viruses or bacteria and their hosts co-evolve in ways that enable the survival and relatively peaceful co-existence of both — as for instance with the zoonoses that became ‘childhood diseases’...
