Afghanistan is responsible for the majority of the world’s supply of poppy crops, which are often used to produce illegal narcotics like heroin. This paper presents an agent-based model that simulates policy scenarios to characterize how the production of poppy can be dampened and replaced with licit crops over time. The model is initialized with spatial data, including transportation network a...

Hypoxysordarin (1), a new sordarin derivative, was isolated from the fermentation broth of the facultative marine Hypoxylon croceum together with a new gamma-lactone, hypoxylactone (2) and sordarin (3). The structures were determined by spectroscopic methods. Sordarin (3) has previously been isolated from the terrestrial Sordaria araneosa (Sordariaceae). Like the parent compound hypoxysordarin ...

A major question in evolution and ecology is why biodiversity is so unevenly distributed across the planet. The most obvious and salient diversity pattern is the order-of-magnitude greater species richness in the tropics compared with the temperate zones. Superimposed on this latitudinal diversity gradient is a much more complex and intricate pattern of regional andmore local biodiversity hotsp...

The self-incompatibility response involves S allele-specific recognition between stigmatic S proteins and incompatible pollen. This response results in pollen inhibition. Defining the amino acid residues within the stigmatic S proteins that participate in S allele-specific inhibition of incompatible pollen is essential for the elucidation of the molecular basis of the self-incompatibility respo...

This study was carried out to determine the effects of diets containing different amounts of poppy seed meal (PSM) and yeast culture (S. cerevisiae) on performance and egg quality parameters of laying hens. A total of 160 laying hens, 40 weeks old, were divided into four groups of 40 hens each, which were in turn subdivided into four subgroups of 10 hens’ experimental replicates. The animals in...
