Roots of a citrus relative, Glycosmis pentaphylla (orangeberry), were shown to inhibit the growth and survival of larvae of the citrus root weevil Diaprepes abbreviatus. Roots of G. pentaphyllaincorporated into the diet of D. abbreviatus increasingly inhibited the growth of neonate larvae with increased concentration of roots, while roots from citrus rootstocks produced little inhibition. The d...

1. Introduction " ...each man possesses opinions about the future, which go by the general name of expectations... " (Plato, Laws 644c, 360 BC) Human behaviour is determined by expectations of future outcomes. While monetary policy discussions have focused almost exclusively on expectations about future inflation, the economic behaviour of households and businesses is driven by expectations abo...

The probability of a stochastic process to first breach an upper and/or a lower level is an important quantity for optimal control and risk management. We present those probabilities for regime switching Brownian motion. In the 2and 3-state model, the Laplace transform of the (single and double barrier) first-passage times is – up to the roots of a polynomial of degree 4 (respectively 6) – deri...

The herbicide cilluron containing cyhalofop-butyl (10%) is an active ingredient. Cyhalofop-butyl has low oral, dermal and inhalation toxicity. In the present study the antigenotoxic effects of Brassica oleracea L. var. italica was evaluated using Allium cepa root chromosomal aberration assay against ciluron. Three types of treatments were given to roots in pre-treatment roots were first treated...

2 Introduction Within the Principle and Parameters model of Universal Grammar (UG), double negatives, which I will henceforth refer to as Negative Concord (NC), have been argued to invoke a fundamental syntactic relation between the head and the specifier of a constituent. More precisely, it has been proposed that sentential negation universally projects a syntactic constituent conform to X' th...

W a revised, standardized set of protocols, the Roots of Human Sociality Project examined whether prior “anomalies” not predicted by any of the available social preference models would reappear in the second round of games played in fifteen small-scale cultures. If they did, we could be more confident that the initial results were robust and not artifacts of an inconsistent methodology. Further...

We identify a class of two-dimensional systems, which includes, for example, standard compressible ow, shallow water equations and nonlinear wave equations, for which a quasi-steady similarity reduction leads to change of type similar to steady transonic ow. For such systems, we outline a strategy for solving Riemann problems. In studying two-dimensional Riemann problems, we have noted a struct...

The leading excitations of the dilute AL model in regime 2 are considered using analytic arguments. The model can be identified with the integrable φ1,2 perturbation of the unitary minimal series ML,L+1. It is demonstrated that the excitation spectrum of the transfer matrix satisfies the same functional equations in terms of elliptic functions as the exact S-matrices of the φ1,2 perturbation do...

Plants are the important sources of drugs. Secondary metabolites are responsible for therapeutic propertiesin plants. Three compounds including (-)-hyoscyamine, its racemate atropine, and scopolamine (hyoscine) are the most famous tropane alkaloids in the Solanaceae familly. Nowadays, attempts to developthese alkaloids in biotechnological procedures which are principally based on the hairy root...
