this article is intended to be a survey on some combinatorial topics in group theory. the bibliography at the end is neither claimed to be exhaustive, nor is it necessarily connected with a reference in the text. i include it as i see it revolves around the concepts which are discussed in the text.

preformulation studies on transdermal dosage forms involve liberal use of animal skin for assessing the permeation characteristics of drugs, influence of permeation enhancers, optimizing the formulation variables etc. the restricted availability of animal skin due to concerns regarding prevention of cruelty to animals has generated considerable interest in developing polymeric films for use as ...

The paper begins with an objection to the DesireBased Reasons Model. The argument from reason-based desires holds that since desires are based on reasons (first premise), which they transmit but to which they cannot add (second premise), they cannot themselves provide reasons for action. In the paper I investigate an attack that has recently been launched against the first premise of this argum...

Most non-economists would question whether economists know anything about culture. Indeed, given some faculty meetings I’ve been through, I imagine they might go so far as to say economists are uncultured. Although the second sentiment probably does go too far, there is certainly merit to the first. In particular, with a few exceptions (notably Kreps, 1990; Crémer, 1993; Lazear, 1995; Hodgson, ...

We present a finite representation of all substitutable services P ′ of a given service P . We show that our approach can be used for at least two applications: (1) given a finite set of services P = {P1, ..., Pn}, we provide a representation of all services P ′ that can substitute every Pi ∈ P, and (2) given a service P ′′ that cannot substitute a service P , we find the most similar service P...

The effects of different kinds of biotic and abiotic stress on crops can be lessened through exogenous application of different biostimulant products. Although some of these products come from enzymatic hydrolysates derived from animal remains, the literature does not contain references to the use of enzymatic hydrolysates obtained from animal hemoglobin, specifi cally porcine blood. With the a...
