Greenhouse studies were conducted to evaluate the effects of soil organic matter content and pH on initial residual weed control with flumioxazin by planting selected species in various lab-made field soils. Initial was determined seeds into soils treated (71 g ha−1). Seeds Echinochloa crus-galli (barnyard grass), Setaria faberi (giant foxtail), Amaranthus retroflexus (redroot pigweed), Abutilo...

Information on the impact of climate change growth weed species and their sensitivity to herbicides could help establish an efficient management strategy. Due excessive use acetolactate synthase (ALS)-inhibitor herbicides, resistance those is increasing globally. It is, thus, crucial find out whether efficacy these will in future due increase temperatures carbon dioxide concentration. Therefore...

Two new Erythrinan alkaloids, cristanines A and B (1, 2), were isolated from the bark of Erythrina crista-galli L. together with nine known Erythrinan alkaloids (3-5, 7-12) and an indole alkaloid (13). The structures of the compounds, cristanines A (1) and B (2), were elucidated by spectroscopic methods. Three of the twelve compounds isolated showed significant inhibitory activity on lipopolysa...

The potential application of in vitro embryo production (IVP) technologies partially depends on the development of reliable, repeatable and efficient techniques for recovery of oocytes from genetically valuable animals. While oocyte collection from living animals has been widely used in the bovine species, its exploitation in sheep has been limited (Galli et al., 2001). Most work reported in sh...

We present a new Monte Carlo algorithm for simulating quantum spin systems which is able to suppress the negative sign problem. This algorithm has only a linear complexity in the lattice size used for the simulation. A general description and a rigorous proof of its correctness is given. Its efficiency is tested on a simple 2-dimensional fermionic model. For this model we show that our algorith...
