In Section 1 we will discuss multi-nucleon transfer reactions with light heavy ions, which can be thought of as competing with complete fusion at higher impact parameters. Quasi-elastic and multi-nucleon transfer reactions with the heaviest projectiles will be discussed in Section 2. In Section 3 we will cover recent developments...
Polyphenol oxidase (PPO) from d'Anjou pears was purified and some
molecular properties were studied. The extraction of PPO was
accomplished in the presence of the phenolic binder AG 2X-8 and Triton
X-100. Chlorophyll pigment was removed by chromatography resulting in
a clear, colorless enzyme extract. Three fractions of pear PPO...
Many pollination studies with honey bees have examined the effect of colony density on crop yield and yet overlook the effect of variation in the population size of these colonies. High colony density in northern highbush blueberry has been met with concerns from beekeepers who feel higher densities will intensify...
Conservation investment in management of at-risk species can be less costly than a delay-and-repair approach implemented after species receive legal protection. The United States Endangered Species Act candidate species designation represents an opportunity to implement proactive management to avoid future listing. Such efforts require substantial investments, and the challenge becomes...

Polyphenol oxidase (PPO) from strawberries was purified,
partially characterized, and used to study its role in the degradation
of anthocyanin pigments. The extraction method included the use of a
buffered solution containing the phenolic binders Polyclar AT and
Amberlite XAD-4. Addition of Triton X-100 resulted in an increase of
the...
INTRODUCTION
On approximately two thirds of the world’s arable land, phosphorus is a plant growth limiting nutrient (Lambers et al., 2013). Agriculture utilizes roughly 80% of the mined phosphate rock as fertilizer, with the remaining 20% being utilized in products such animal feed supplements, food preservatives, pesticides, fungicides, herbicides, water...
The greater sage-grouse, an iconic ground-dwelling bird of the West, has experienced significant population declines during the past 50 years from habitat loss. The U.S. Fish and Wildlife Service (FWS) designated sage grouse in 2010 as a candidate for listing under the Endangered Species Act (ESA).
In September 2015, the...
The northern Los Angeles basin is influenced by two structural styles: the west-trending compressional Transverse Ranges to the north, and the strike-slip Peninsular Ranges to the south. The interaction of these two structural styles has resulted in a complex fold fault belt at the northern margin of the Los Angeles...
